Opinion
After a jury trial, the defendant, Solomon Boyd, was convicted of murder in violation of General Statutes § 53a-54a. The trial court rendered judgment in accordance with the verdict, and the defendant now appeals 1 from the judgment of conviction. The defendant claims that the trial court improperly: (1) denied his motion to suppress certain evidence on the ground that it was seized in violation of his rights under the fourth amendment to the United States constitution 2 and article first, § 7, of the Connecticut constitution; 3 (2) admitted evidence of uncharged misconduct; (3) admitted evidence that the defendant had invoked his right to remain silent in violation of his rights under the fifth amendment to the United States constitution; 4 and (4) failed to give a special credibility instruction on the testimony of an informing witness. We conclude that, although the defendant had a legitimate expectation of privacy in his cell phone, the automobile exception to the constitutional requirement for a search warrant applied under New York law. We also reject *711 the defendant’s other claims. Accordingly, we affirm the judgment of conviction.
The jury reasonably could have found the following facts. In 2001 and early 2002, the defendant lived in Mamaroneck, New York, with his girlfriend, Melissa Gagliardi. The defendant was a drug dealer. Carlos Barradas, the victim, spent a large amount of time at the defendant’s apartment, where he helped the defendant with his drug business. In return, the defendant provided drugs to the victim. The victim also purchased drugs from the defendant on an almost daily basis.
In early January, 2002, a gold bracelet belonging to the defendant was missing from the apartment. The defendant believed that the victim had stolen the bracelet and became upset with him. On the night of January, 16, 2002, at approximately 10 p.m., the defendant told Gagliardi that he and the victim were going to go to Mount Vernon, New York, to buy drugs. The defendant and the victim took the victim’s car. Instead of driving to Mount Vernon, however, they drove to Norwalk. They arrived at an area near the intersection of Merritt Street and Chestnut Street at approximately 11:48 p.m. The defendant then shot the victim with a .45 caliber semiautomatic gun. The victim exited from the car and tried to flee, but a fence blocked his way. The defendant, who also had exited the car, shot the victim again. The victim then entered and exited the car again in an attempt to escape from the defendant. The defendant ultimately shot the victim several times in front of the car, where the victim fell. Police arrived at the scene within minutes of the shooting and found the victim still alive. They took him to Norwalk Hospital where he was pronounced dead at 12:15 a.m.
Later that morning, when the defendant arrived back at his apartment in Mamaroneck, he was wearing a woman’s sweatshirt. Gagliardi asked him where he had *712 acquired it, and the defendant told her that he had needed to change his clothes in order to get rid of “ ‘evidence’ ”or“ ‘gun’s powder.’ ” At some point, Gagliardi asked the defendant where the victim was and the defendant told her that he had killed him by shooting him multiple times. He also indicated that his cousin, Kevin Thomas, had been present during the murder.
In March, 2004, the defendant was arrested and charged with murder. After a trial, the jury found him guilty of murder and the trial court rendered judgment in accordance with the verdict. This appeal followed.
I
We first address the defendant’s claim that the trial court improperly denied his motion to suppress certain evidence that he claims was seized without a valid search warrant in violation of his rights under the fourth amendment to the United States constitution and article first, § 7, of the Connecticut constitution. We conclude that the evidence was admissible under the automobile exception to the constitutional requirement for a search warrant.
The following undisputed facts are relevant to this claim. In January and February, 2002, the Mamaroneck police department was investigating the defendant for suspected drug sales. On February 1,2002, Joseph Comblo, a detective with the Mamaroneck police department, executed a search warrant in connection with the investigation. Both the warrant and. the affidavit attached to the warrant were captioned: “FOR THE PREMISES AND PERSONS OF: SOLOMON BOYD, 627 MAMARONECK AVENUE, MAMARONECK, NEW YORK, APARTMENT # 3 . . . AND FOR THE PERSON OF SOLOMON BOYD AND ANY PERSON THEREIN.” The body of the search warrant stated: “You are therefore commanded ... to make an immediate search of 627 Mamaroneck Ave. . . . Mamaroneck, New York *713 ... for crack cocaine and cocaine, narcotics paraphernalia, including but not limited to plastic bags, records of ownership or use of this location, including trace evidence, records of narcotics transactions, any safe and its contents, computers, computer programs, computer data, and [United States] [c]urrency used to purchase crack cocaine and cocaine . . . .”
Because the Mamaroneck police were aware that the Norwalk police department was investigating the defendant in connection with the victim’s murder, Robert Holland, a sergeant with the Mamaroneck police department, invited Arthur Weisgerber and Charles Chrzanowski, detectives with the Norwalk police department, to accompany the Mamaroneck police during the search of the defendant’s apartment. The Mamaroneck police department executed the warrant at approximately 7:45 p.m. on February 8, 2002. Weisgerber and Chrzanowski arrived at the apartment after the search had begun. They did not participate in the search, but remained in the kitchen of the apartment. 5 They attended the search in the hope that, while the Mamaroneck police were searching for drugs, they would find in plain view evidence related to the victim’s murder, such as a gun, ammunition or bloody clothes. The Mamaroneck police found crack cocaine, drug paraphernalia, a scale, a razor blade and a computer in the apartment. Gagliardi was present during the search and the police arrested her on drug charges. The police found no evidence related to the murder.
During the search, Holland received a radio call that other Mamaroneck police officers had stopped the defendant nearby as he was returning to the apartment *714 in his car. Holland and Weisgerber went to the location where the defendant had been stopped. By the time they arrived, the other police officers already had arrested the defendant for drug offenses on the basis of the evidence seized at the apartment. Holland and Weisgerber noticed a cell phone on the passenger seat of the car that the defendant had been driving.
Later that night, Weisgerber and Chrzanowski went to the Mamaroneck police station to interview Gagliardi about the murder. While they were waiting to interview Gagliardi, Andy Genovese, a detective with the Mamaroneck police department, was at his desk nearby, scrolling through the numbers on the cell phone that had been taken from the defendant’s car. 6 Genovese announced several telephone numbers that he had found on the cell phone, including the cell phone’s subscriber number. Chrzanowski recorded the number in his notes.
Thereafter, Weisgerber prepared and executed a search warrant on Sprint Spectrum L.P., the wireless telecommunications company that serviced the cell phone for the telephone records related to the cell phone. The cell phone records revealed that the account for the cell phone was in the defendant’s name. The records also showed that, in the hour before the victim’s murder, calls from and to the cell phone had been routed through a series of telecommunications towers progressing in a northeasterly direction from Mamaroneck to Norwalk. A number of cell phone calls that had been made and received minutes before the murder had been routed through a tower located approximately five blocks north of the murder scene. The cell phone records further showed that, beginning minutes after the murder, a number of calls from and to the cell phone *715 had been routed through a series of towers progressing in a southwesterly direction from Norwalk to Mamaroneck.
In addition, the cell phone records revealed that, shortly after the murder, several calls originating with the cell phone had been made to the telephone of Sally Williams, who is Gagliardi’s mother. Gagliardi’s cousin, Joanne Gentile, who was one of the defendant’s drug customers, was living with Williams at that time. Gentile testified at trial that the defendant had called her in a panicked state on the night of the murder and had asked her to go to his apartment to tell Gagliardi to call him or to answer his telephone calls. Gagliardi testified that, after Gentile came to the apartment, she answered the telephone and the defendant asked her to call his sister to ask her to provide him with an alibi. The defendant also asked Gagliardi to say that he had been at his sister’s house getting his hair done or that he had been at home with Gagliardi. Gagliardi refused and hung up the telephone.
Before trial, the defendant filed a motion to suppress the cell phone records and any other evidence to which the police had been led as the result of seizing the cell phone. At the suppression hearing, Holland testified that, although the warrant did not specifically authorize the police to seize cell phones, the Mamaroneck police department considered cell phones to constitute drug paraphernalia and records, which were covered by the warrant. Gagliardi testified that, when the Norwalk police interviewed her on the night of the search, she knew the defendant’s cell phone number and that the carrier for the cell phone was “Sprint.” The defendant testified about the circumstances surrounding certain statements that he had made after his arrest for murder, but he did not testify regarding the cell phone.
The defendant argued at the suppression hearing that the cell phone was not covered by the search warrant *716 because the warrant authorized a search only of the defendant’s apartment, not his person. He further argued that the seizure of the cell phone was not valid under any of the exceptions to the fourth amendment warrant requirement. The state argued that, because the search warrant referred to the defendant’s person, it was not limited to his apartment. It further argued that, even if the search warrant did not authorize the seizure and search of the cell phone, the search was valid under the automobile exception to the constitutional requirement for a warrant, the search incident to lawful arrest exception, the doctrine of exigent circumstances and the inevitable discovery doctrine.
The trial court concluded that the search warrant had authorized the seizure and search of the cell phone because it authorized the search of the defendant for evidence of drug activity and the evidence presented at the suppression hearing showed that the Mamaroneck police had seized the cell phone on the basis of their experience that cell phones contain such information. The trial court further concluded that, even if the search warrant had not authorized the seizure and search of the cell phone, the inevitable discovery doctrine applied because Weisgerber and Chrzanowski would have learned the cell phone number from Gagliardi when they interviewed her on the night of the search if Genovese had not revealed the number to them. Accordingly, the trial court denied the defendant’s motion to suppress all evidence developed as the result of the seizure of the cell phone.
The defendant now claims that the trial court improperly determined that the search warrant authorized the seizure and search of the cell phone and that, even if the warrant did not authorize the search, the inevitable discovery doctrine applied. The state disputes these claims and claims as alternate grounds for affirmance that the defendant had no reasonable expectation of *717 privacy in his cell phone number and that the search was valid under both the automobile exception and the search incident to arrest exception. Finally, the state claims that, even if the search was unconstitutional, the admission of the evidence related to the cell phone was harmless. We conclude that the defendant had a reasonable expectation of privacy in the contents of his cell phone, but that the search of the cell phone was valid under the automobile exception. Accordingly, we need not address the defendant’s claims that the trial court improperly concluded that the search warrant authorized the search of the cell phone and that the inevitable discovery doctrine applied.
We begin with the standard of review for a motion to suppress. “It is axiomatic that [ujnder the exclusionary rule, evidence must be suppressed if it is found to be the fruit of prior police illegality.” (Internal quotation marks omitted.)
State
v.
Santos,
*718 A
We first consider the state’s claim that the trial court’s denial of the defendant’s motion to suppress may be affirmed on the alternate ground that the defendant had no reasonable expectation of privacy in the contents of his cell phone under the fourth amendment. 7 We disagree.
“The touchstone to determining whether a person has standing to contest an allegedly illegal search is whether that person has a reasonable expectation of privacy in the invaded place. . . . Absent such an expectation, the subsequent police action has no constitutional ramifications. ... In order to meet this rule of standing ... a two-part subjective/objective test must be satisfied: (1) whether the [person contesting the search] manifested a subjective expectation of privacy with respect to [the invaded premises]; and (2) whether that expectation [is] one that society would consider reasonable. . . . This determination is made on a case-by-case basis. . . . Whether a defendant’s actual expectation of privacy ... is one that society is prepared to recognize as reasonable involves a fact-specific inquiry into all the relevant circumstances.” (Citations omitted; internal quotation marks omitted.)
State
v. Hill,
“The courts have identified a number of factors indicating that a person’s expectation of privacy in a particular place is one that society is not prepared to recognize as reasonable.”
State
v.
Mooney,
218 Conn.
*719
85, 96,
“[Although the inquiry in determining whether there is a reasonable expectation of privacy involves an inquiry into the particular place invaded, when the search is of a [container] the principal ‘place’ for fourth amendment purposes is the interior of the [container] and its contents.”
State
v.
Mooney,
supra,
The state argues that the defendant failed to establish that he had a reasonable expectation of privacy in the contents of his cell phone because he presented no evidence that he owned it. The state further argues that, even if the defendant owned the cell phone, mere ownership or possession is not sufficient to establish a reasonable expectation of privacy; see
United States
v.
Salvucci,
The evidence presented at the suppression hearing established that the police seized the cell phone from the passenger seat of the car that the defendant had been driving. Gagliardi testified that the defendant possessed a cell phone at the time of the search. In addition, the cell phone records themselves indicated that the cell phone belonged to the defendant. Finally, the defendant’s exclusive possession is implicit in the state’s claim that the cell phone records showed that the defendant had traveled to Norwalk on the night of the murder and that the defendant had been in possession of the cell phone that night.
8
Accordingly, we conclude that
*721
the trial court reasonably could have concluded that the defendant owned the cell phone and exercised exclusive control over it, and that he therefore had a reasonable expectation that others would not have access to it without his permission. We conclude, therefore, that he had a reasonable expectation of privacy in the cell phone. Cf.
State
v.
Sealy,
supra,
*722
The state also claims, however, that even if the defendant owned and controlled the cell phone, he failed to establish that he had a reasonable expectation of privacy in the cell phone number because he presented no evidence that he had made any attempt to keep it private. In support of this claim, the state relies on
United States
v.
Fierros-Alavarez, 547
F. Sup. 2d 1206 (D. Kan. 2008). In that case, the court concluded that, because the defendant had lawful possession and control of his cell phone when it was seized and searched by the police, he had a subjective expectation of privacy in it. Id., 1210. The court also concluded, however, that the defendant had no reasonable expectation of privacy in the cell phone’s recent call directory showing the numbers that the defendant had called from the cell phone because he had provided that information to third parties. Id., 1210-11. In support of this conclusion, the court relied on
Smith
v.
Maryland,
We do not find the court’s reasoning in
Fierros-Alavarez
to be persuasive. In
Smith
and
Forrester,
the government had not obtained the dialed telephone numbers and e-mail addresses from an item or area in which
*723
the defendant had a reasonable expectation of privacy, but had obtained the information from, respectively, the telephone company and the Internet provider. See
Smith
v. Maryland, supra,
B
We next address the state’s alternate ground for affirmance that the seizure of the cell phone and the search of its contents were valid under the automobile exception to the warrant requirement under the fourth amendment to the United States constitution. The state contends that, although the search would have been unconstitutional under article first, § 7, of the Connecticut constitution if conducted in Connecticut by Connecticut police; see
State
v.
Miller,
At the outset, we address the defendant’s contention that the record is not adequate for review of the state’s claimed alternate ground for affirmance because the trial court did not make factual findings regarding the applicability of the automobile exception. We disagree. The trial court found that the cell phone was on the front passenger seat of the defendant’s car when he was arrested. The court also expressly found that it was not clear when the cell phone had been seized from *725 the car on the basis of the evidence presented at the suppression hearing, but that the cell phone was in the possession of the Mamaroneck police when they returned to the police station. Finally, the trial court found that “the Norwalk police were not implicated in the determination of the [cell phone] number; it was solely the Mamaroneck police who did so.” As we discuss subsequently in this opinion, we conclude that these factual findings are sufficient for this court to determine whether the state met its burden of proving the automobile exception to the warrant requirement.
Accordingly, we turn to a review of the law governing the automobile exception to the constitutional requirement for a warrant. “Under both the federal and the state constitutions, the police must first obtain a warrant before conducting a search, unless an exception to the warrant requirement applies.” (Internal quotation marks omitted.)
State
v.
Smith,
“In
Carroll
v.
United States,
*726 hi Miller, this court rejected what it characterized as a request to expand the automobile exception to permit “a warrantless automobile search that is conducted after the automobile has been impounded at a police station.” 11 Id., 383. The court reasoned that, because the exception is justified only by “the inherent mobility of automobiles and the latent exigency that that mobility creates”; id., 384-85; and because those circumstances no longer exist after the automobile has been impounded, “a warrantless automobile search supported by probable cause, but conducted after the automobile has been impounded at the police station, violates article first, § 7, of the Connecticut constitution.” Id., 386-87.
In the present case, the state does not dispute that, if Connecticut police had seized and searched the defendant’s cell phone in this state, the search would have been unconstitutional under Miller and, therefore, the evidence would have been inadmissible. Thus, the state implicitly concedes that the evidence would not support a finding that the police seized the cell phone when they arrested the defendant, and that it must therefore be presumed that they seized the cell phone from the defendant’s car after it was impounded at the police station. The state argues, however, that, because the evidence was obtained in New York by New York police officers in compliance with New York law, the exclusionary rule does not bar its admission merely because the search would have violated this state’s constitutional law if it had occurred in this state. We agree with the state that: (1) the legality of the search was governed by New York law; and (2) under New York law, the search was legal.
*727
We first consider whether the legality of the search should be determined under Connecticut law or New York law. The majority of courts that have considered the issue have concluded that “it does not offend the constitutional principles of a forum jurisdiction to allow the transfer of criminal evidence from the officers of another jurisdiction to those of the forum when the evidence has been obtained lawfully by the former without any assistance by the latter,” even when the search would have been illegal in the forum jurisdiction.
12
State
*728
v.
Mollica,
Like these courts, this court previously has recognized that “[t]he purpose of the exclusionary rule is not to redress the injury to the privacy of the search victim .... Instead, the rule’s prime purpose is to deter future unlawful police conduct and thereby effectuate the guarantee of the [fjourth [a]mendment against unreasonable searches and seizures .... Application of the rule is thus appropriate in circumstances in which this purpose is likely to be furthered.” (Internal quotation marks omitted.)
Payne
v.
Robinson,
The defendant contends, however, that even if the exclusionary rule ordinarily does not apply to evidence that was lawfully obtained in another jurisdiction when the official conduct at issue would have been illegal in this state, the exclusionary rule does apply when the
*730
officers from the other jurisdiction acted as agents for officers of this state. In support of this contention, the defendant relies on
Lustig
v.
United States,
We need not decide in the present case, however, whether participation by officials of this state in a search that is legal in the search jurisdiction, but which would be illegal in this state, renders the evidence inadmissible in this state and, if so, what level of participation by this state’s officials is required, because, upon a careful review of the record, we conclude that the trial court’s finding that “the Norwalk police were not implicated in the determination of the cell phone number; it was solely the Mamaroneck police who did so,” was supported by substantial evidence. The evidence shows that Norwalk police were not present while the Mamaroneck police engaged in conduct that the defendant claims would have been unconstitutional if conducted by Connecticut officials, namely, the seizure of
*732
the defendant’s cell phone after his automobile was impounded. Moreover, there was no evidence that the Norwalk police had any knowledge that the Mamaroneck police intended to engage in such conduct or that they had influenced the Mamaroneck police in any way.
15
In addition, although the Norwalk police were present in the police station when Genovese searched the contents of the cell phone and announced the cell phone number, they were there to interview Gagliardi, not to obtain information about the search from the Mamaroneck police. Indeed, there was no evidence that the Norwalk police knew that the Mamaroneck police had seized the cell phone, that they would search its contents or that they would announce their findings. We conclude, therefore, that there was no evidence to support a conclusion that the Norwalk police had intended to violate the state constitution by “circuitous and indirect methods.”
Byars
v.
United States,
supra,
We turn, therefore, to that question. Under New York constitutional law, “when the occupant of an automobile is arrested, the very circumstances that supply probable cause for the arrest may also give the police probable cause to believe that the vehicle contains contraband, evidence of the crime, a weapon or some means of escape. If so, a warrantless search of the vehicle is authorized ... as a search falling within the automobile exception to the warrant requirement . . . .”
People
v.
Blasich,
supra,
*735 The defendant in the present case does not dispute that, on the basis of the evidence that the Mamaroneck police found in his apartment, they had probable cause to arrest him for drug offenses. The trial court found that the cell phone was visible on the front seat of the defendant’s car when he was arrested and that the Mamaroneck police consider cell phones to constitute drug paraphernalia and records because they are likely to contain information about drug transactions. 18 Because the police had probable cause to believe that the defendant was selling drugs, because the defen *736 dant’s cell phone was visible in the defendant’s car when the police arrested him and because the police had probable cause to believe that the cell phone contained evidence of drug activity, we conclude that the police had probable cause to seize and search the contents of the cell phone under the automobile exception as applied in New York.
In addition, as we have indicated, the New York Court of Appeals has held that the automobile exception “is equally applicable whether the search is conducted at the time and place where the automobile was stopped or whether, instead, the vehicle is impounded and searched after removal to the police station . . . .”
People
v.
Blasich,
supra,
II
The defendant next claims that the trial court improperly admitted evidence of uncharged misconduct. We disagree.
The following facts and procedural history are relevant to this claim. Before trial, the state filed amotion in limine seeking to introduce evidence that the defendant previously had engaged in misconduct that was similar to the charged conduct in this case. The defendant filed *737 a motion to exclude the evidence. At the suppression hearing, the state presented an offer of proof in the form of testimony by Gentile that the defendant had driven her to the same location in Norwalk where the victim had been murdered and had threatened her with harm. Specifically, Gentile testified that, in December, 2001, 19 after she had stolen money and cocaine from the defendant, the defendant told her that he wanted to go with her to the Bronx to obtain more drugs for his drug business. Gentile got into a car with the defendant and the defendant’s cousin, Thomas, who was driving. Instead of driving south toward the Bronx, however, Thomas drove north toward Connecticut. At some point, the defendant pointed a gun at Gentile and placed handcuffs on her. After they entered Connecticut, Thomas stopped the car in an area where there were warehouses and a gate with two bars. The defendant then questioned Gentile about the theft of his money and his drugs. When Gentile refused to admit that she had stolen them, the defendant stated that he was going to get some gas and bum Gentile. He then got out of the car, left the area and returned with a can of gas. He then left again. Some time later, he called Thomas’ cell phone, and Thomas told Gentile that the defendant was at her house with Gagliardi and Williams and he wanted Gentile to tell them to give him the money. Gentile did so. The defendant returned to the car a couple of hours later and they drove to Port Chester, where Gentile was released.
In April, 2005, Gentile told Weisgerber about the incident. Weisgerber brought Gentile to several locations in Norwalk to see if she could identify the location where the defendant had brought her. Gentile did not *738 recognize the first three locations, but recognized the fourth one. Weisgerber then took Gentile around the comer from that location and told her that the police had found the victim there.
During argument on the state’s motion in limine, the state argued that Gentile’s testimony was relevant to the issue of identity because the defendant’s treatment of Gentile was so similar to the perpetrator’s treatment of the victim. The state agreed, however, that it would not elicit testimony about the defendant’s threat to use gasoline to bum Gentile. The defendant argued that the evidence was highly prejudicial to the defendant in that it tended to show that the defendant had a propensity to engage in this type of conduct and that the incident with Gentile was not sufficiently similar to the murder to come within the exception to the bar on propensity evidence for signature crimes. The trial court concluded that the conduct was sufficiently similar to be probative on the issue of identity and that its probative value outweighed its prejudicial effect. Accordingly, it granted the state’s motion to admit the evidence.
At trial, Gentile testified substantially in accordance with her offer of proof testimony at the suppression hearing, with the exception that she did not testify about the defendant’s threat to bum her with gasoline. The trial corut immediately cautioned the jury that the evidence was being introduced solely for the purpose of proving the identity of the perpetrator, not to show that the defendant was a person of bad character or had a propensity to commit crime. The court further instructed the jury that, if it determined that the uncharged misconduct was not similar to the charged conduct, it could not consider it for any purpose. The trial court repeated these instructions to the jury in its final jury charge. 20
*739 The defendant now claims that the trial court improperly admitted Gentile’s testimony about the defendant’s misconduct toward her because the conduct was not sufficiently similar to establish identity. We agree with the defendant that the trial court improperly admitted the evidence. We also conclude, however, that its admission was harmless.
Our standard of review for evidentiary claims is well settled. “To the extent [that] a trial court’s admission of evidence is based on an interpretation of the Code of Evidence, our standard of review is plenary. For example, whether a challenged statement properly may be classified as hearsay and whether a hearsay exception properly is identified are legal questions demanding plenary review.”
State
v.
Saucier,
“As a general rule, evidence of . . . other crimes is inadmissible to prove that a defendant is guilty of the crime charged against him.
22
. . . The rationale [for] this rule is to guard against its use merely to show an evil disposition of an accused, and especially the predisposition to commit the crime with which he is now charged. . . . The fact that such evidence tends to prove the commission of other crimes by an accused does not render it inadmissible [however] if it is otherwise relevant and material. . . . Such evidence is admissible for other purposes, such as to show intent, an element [of] the crime, identity, malice, motive or a system of criminal activity.” (Citations omitted; internal quotation marks omitted.)
State
v.
Figueroa,
“The first threshold for the use of evidence of other crimes or misconduct on the issue of identity is that the methods used be sufficiently unique to warrant a reasonable inference that the person who performed one misdeed also did the other. . . . McCormick points out that in proffering other crime evidence [t]o prove other like crimes by the accused so nearly identical in method as to earmark them as the handiwork of the accused . . . much more is demanded than the mere repeated commission of crimes of the same class, such as repeated burglaries or thefts. The device used must be so unusual and distinctive as to be like a signature.”
*741
(Citation omitted; internal quotation marks omitted.)
State
v.
Figueroa,
supra,
“[T]he fact that some of the similarities between the offenses were legal or relatively common occurrences when standing alone does not . . . negate the uniqueness of the offenses when viewed as a whole. It is the distinctive combination of actions which forms the signature or modus operandi of the crime . . . and it is this criminal logo which justifies the inference that the individual who committed the first offense also committed the second. . . . The process of construing an inference of [ijdentity . . . consists usually in adding together a number of circumstances, each of which by itself might be a feature of many objects, but all of which together make it more probable that they coexist in a single object only. Each additional circumstance reduces the chances of there being more than one object so associated.” (Citations omitted; internal quotation marks omitted.) Id., 164.
In the present case, the state argues that the misconduct evidence was sufficiently similar to the murder to establish that the defendant was the perpetrator because both Gentile and the victim were customers of the defendant’s drug business; the defendant was angry at both Gentile and the victim because he believed that they had stolen from him; the defendant used the same ruse to lure Gentile and the victim to accompany him; the defendant brought both Gentile and the victim to the same place; and Thomas had accompanied the defendant during both incidents.
As we have indicated, however, evidence of other misconduct is admissible
only
for the purpose of raising an inference that “the person who performed one misdeed also did the other.” (Internal quotation marks omitted.) Id., 163. Thus, misconduct evidence is admissible
only
to show that the defendant, rather than
*742
another person, committed the charged crime. Regardless of how similar the uncharged misconduct is to the charged conduct, the uncharged misconduct may not be used to prove that, because the defendant committed the same type of conduct before, he committed the charged conduct. See
State
v.
Vorhees,
In the present case, it is obvious that the jury could not have concluded that a person other than the defendant had been angry with the victim because of the theft of the defendant’s bracelet and had tricked the victim into accompanying him on a drive on the night *743 of the murder. Rather, if it disbelieved the evidence tending to prove those facts, it could have concluded only that the conduct did not occur. Thus, the state was not using the similarity between the defendant’s prior conduct with Gentile and the defendant’s conduct with the victim to show the defendant, and not another person, had engaged in that conduct toward the victim, but to corroborate the evidence that he had engaged in that conduct by showing that he previously had engaged in extremely similar misconduct. As we have indicated, the evidence was not admissible for that purpose. We conclude, therefore, that the trial court improperly admitted the evidence.
We must determine, therefore, whether the improper admission of the misconduct evidence was harmful. “When an improper evidentiary ruling is not constitutional in nature, the defendant bears the burden of demonstrating that the [impropriety] was harmful. ... [A] nonconstitutional [impropriety] is harmless when an appellate court has a fair assurance that the [impropriety] did not substantially affect the verdict.” (Citation omitted; internal quotation marks omitted.)
State
v.
Orr,
We conclude that the admission of the misconduct evidence was harmless. First, Gentile’s misconduct testimony did not cast the defendant in a significantly worse light than the other evidence presented at trial. Both Gagliardi and Gentile testified that the defendant ran a drug selling business. Moreover, contrary to the defendant’s claim that the misconduct evidence was the only evidence tending to show that the defendant was a violent person, Gagliardi testified that she had discovered in December, 2001, that the defendant carried a gun. The defendant told her at that time that he needed the gun for protection. Gagliardi also testified that the defendant had told her that he had shot the victim multiple times.
*744 Second, the jury had before it other strong evidence of the defendant’s guilt. Again, Gagliardi testified that the defendant had confessed to her on the morning following the murder that he had killed the victim by shooting him multiple times and that he had asked her to provide him with an alibi. Gagliardi’s testimony also showed that the defendant had a motive to kill the victim. In addition, the cell phone records provided strong evidence that the defendant had been in the area of Norwalk where the murder occurred at the time of the murder and corroborated the testimony that he had spoken by telephone to Gagliardi and Gentile shortly after the murder.
Third, the trial court forcefully instructed the jury that it could not use the evidence to infer that the defendant had a bad character or that he had a propensity to commit criminal acts both immediately after Gentile’s misconduct testimony and during its final instructions. Under these circumstances, we have a fan-assurance that the misconduct evidence did not substantially affect the verdict.

We next address the defendant’s claim that the trial court violated his fifth amendment right to remain silent when it admitted evidence that he had invoked that right during questioning by the police. He further claims that the state violated his fifth amendment right when it commented on that evidence during closing arguments. We disagree.
The following facts and procedural history are relevant to our resolution of this claim. On March 29, 2004, Weisgerber and Andrew Gail, a lieutenant with the Nor-walk police department, interviewed the defendant regarding the victim’s murder. Before trial, the defendant filed a motion to suppress the statements that the defendant made during this interview on the ground *745 that the defendant had made the statements without having been properly advised of his Miranda rights, 24 and that he had made them involuntarily. The defendant testified concerning the interview at the February 28, 2006 suppression hearing, and the state introduced the written police report of the interview. The trial court denied the motion to suppress on March 2, 2006. 25
At trial, the prosecutor started to question Weisgerber about the interview and the police report and the defendant objected. The trial court excused the jury and noted that the statements that the defendant had made during the interview had been the subject of the defendant’s motion to suppress, which the court had denied. The trial court acknowledged, however, that the defendant had reserved his right to object to the admission of the statements on grounds that he had not raised in the motion to suppress. Accordingly, it held a conference in chambers during which it heard the parties’ arguments and ruled on the portions of the written police report about which Weisgerber would be permitted to testily.
After the conference in chambers, the parties returned to the courtroom and defense counsel placed on the record her objections to the court’s rulings. With respect to the defendant’s statement in the written police report that he was not ready to share his opinion about who had committed the murder, defense counsel objected to its admission on the ground that the defendant was entitled to invoke his right to remain silent. She also objected to the admission of the defendant’s statement that Weisgerber had “asked a very good question” because it was intertwined with his statement that he was not going to discuss the crime scene, which *746 the trial court had excluded as an invocation of the defendant’s rights. Defense counsel further objected to the admission of the defendant’s statements that he was not willing to divulge information because the police were not going to release him, claiming that the statements were invocations of his right to remain silent.
Thereafter, the prosecutor continued his examination of Weisgerber. Weisgerber testified that, at the beginning of the interview, he advised the defendant of his Miranda rights. The defendant waived those rights and Weisgerber asked him when he had learned about the victim’s death and when he had last seen the victim. The defendant said that he could not recall. Weisgerber then asked the defendant whether he was willing to answer questions at that time or if he would prefer to answer them at another time. The defendant responded that there would be plenty of time to talk later. When Weisgerber responded that this would be his only opportunity to talk to the police, the defendant responded that there was no hurry to discuss details. After answering several more questions, the defendant stated that the police had arrested the wrong person. When Weisgerber asked why he had made that statement, the defendant responded that he did not want to answer the question at that time because he knew that the police would not release him that night.
Weisgerber further testified that the defendant initially had declined Weisgerber’s request that he give a written statement about the night of the murder, but ultimately indicated that he would like to provide one. The defendant repeatedly denied in his written statement that he had hurt the victim. The defendant then asked Weisgerber whether he believed that the defendant had murdered the victim, and Weisgerber replied that he did. Weisgerber testified that the defendant’s *747 demeanor did not change when Weisgerber made this statement.
Weisgerber further testified that, after the defendant answered several more questions, Weisgerber asked him whether he had ever been to Norwalk. The defendant responded that he had family in Connecticut, but that he would not speak about his family. Weisgerber testified that he then asked the defendant if he had gone to Norwalk with the victim and the defendant answered that he had not. Weisgerber again asked the defendant if he had gone to Norwalk with the victim on the night of the murder, and the defendant stated twice that “that was a very good question.” Defense counsel then interrupted Weisgerber and asked for “one moment with counsel.” The prosecutor then asked Weisgerber to continue his testimony and Weisgerber stated that the defendant had advised him that, “at that point he was not going to speak about the crime scene.” The trial court asked defense counsel whether she objected to this testimony, and she indicated that she had no objection.
Weisgerber then testified that, shortly after stating that he was not going to talk about the crime scene, the defendant asked to go to the bathroom. Upon his return, he indicated that he knew the truth about the murder. When the prosecutor asked Weisgerber whether the defendant had been willing to tell the police what he knew at that point, Weisgerber responded that he had not. The prosecutor then asked why the defendant had been unwilling to talk to the police and Weisgerber stated that the defendant had said that he wanted to speak to counsel first. Defense counsel again interrupted and stated that the trial court had granted the defendant’s motion to exclude that portion of the written report of the interview. After conferring with counsel, the trial court directed the jury to “completely disregard” Weisgerber’s testimony that the defendant *748 was not going to tell the police what he knew about the murder without talking to an attorney first.
The next day, the defendant filed a motion for mistrial claiming that the state had violated the trial court’s ruling excluding the defendant’s statement that he would not tell the police what he knew about the murder until he talked to an attorney. She argued that the testimony suggested that the defendant had been “trying to hide something” by invoking his constitutional rights. The prosecutor conceded that Weisgerber inadvertently had violated the court’s order, but argued that the defendant had not been prejudiced. The trial court concluded that the defendant had not been prejudiced by Weisgerber’s brief reference to the defendant’s request for counsel and denied the defendant’s motion for a mistrial.
During closing arguments, the prosecutor referred to the statements made by the defendant during the March 29,2004 interview. The prosecutor stated, “isn’t it interesting that [the defendant] doesn’t want to talk about where he was on the night [of the] murder nor what he did?”
The defendant now claims that the admission of Weisgerber’s testimony about these matters violated his fifth amendment rights under
Doyle
v.
Ohio,
We first address the defendant’s claim that the trial court improperly allowed Weisgerber to testify that the defendant had stated repeatedly that he did not want to tell the police what he knew about the murder. “In
Doyle .
. . the United States Supreme Court held that the impeachment of a defendant through evidence of his silence following his arrest and receipt of
Miranda
warnings violates due process. The court based its holding [on] two considerations: First, it noted that silence in the wake of
Miranda
warnings is insolubly ambiguous and consequently of little probative value. Second and more important[ly], it observed that while it is true that the
Miranda
warnings contain no express assurance that silence will carry no penalty, such assurance is implicit to any person who receives the warnings. In such circumstances, it would be fundamentally unfair and a deprivation of due process to allow the arrested person’s silence to be used to impeach an explanation subsequently offered at trial.” (Internal quotation marks omitted.)
State
v.
Bell,
Doyle
is not applicable, however, when the defendant has waived his right to remain silent. See
State
v.
Talton,
In the present case, the defendant waived his Miranda rights and told the police that he could not recall how he had learned of the victim’s death or when he had last seen the victim. He also stated that the police had arrested the wrong person and that he knew the truth about the murder. In addition, he gave a written statement in which he repeatedly denied that he had hurt the victim. Interspersed among these exculpatory statements, the defendant also made statements that he was not yet ready to tell the police everything that he knew about the murder and that he was not willing to discuss the crime scene. 26 He did not ask the police to end the interrogation, however, or indicate that he was reluctant to answer any inquiries until the point that he stated that he wanted to speak to an attorney, at which point the police ended the interview. Accordingly, we conclude that the defendant had not invoked his right to remain silent by stating that he was not yet ready to discuss everything that he knew about the murder and, therefore, Weisgerber’s testimony about those statements did not violate Doyle? 27 See id., 296 *751 (when defendant refused to divulge certain information about crime to police, but “did not ask that the interrogation be ended or indicate reluctance to answer other inquiries” defendant failed to invoke fifth amendment right to remain silent).
We next address the defendant’s claim that the admission of Weisgerber’s testimony that the defendant initially declined to give a written statement violated
Doyle.
This claim was not preserved at trial and the defendant therefore seeks review under
State
v.
Golding,
The following additional facts are relevant to our resolution of this claim. When the prosecutor asked Weisgerber whether the defendant had been willing to give a written statement, Weisgerber responded that the defendant had declined to do so. The prosecutor then asked, “A written statement?”, thereby suggesting that he was surprised by Weisgerber’s answer. When Weisgerber repeated his response, the prosecutor asked, “Did there come [any time] where [the defendant] decided he wanted to put something down in writing?” and Weisgerber answered affirmatively. It is
*752
clear, therefore, that the prosecutor had elicited Weisgerber’s testimony that the defendant had initially declined to give a written statement in an attempt to explain the process by which the police had obtained the defendant’s written statement, not to raise an inference that the defendant had been reluctant to cooperate with the police. “We have held that evidence of a defendant’s silence that is . . . presented to show the investigative effort made by the police and the sequence of events as they unfolded, is not inadmissible under
Doyle
. . . .”
State
v. Jones,
We next address the defendant’s claim that Weisgerber’s testimony that the defendant’s demeanor did not change when Weisgerber told him that he believed that he had murdered the victim violated
Doyle.
Because this claim was not preserved at trial, we review it under
Golding.
In support of this claim, the defendant relies on this court’s decision in
State
v.
Plourde,
In the present case, we have already concluded that the defendant did not invoke his constitutional right to remain silent until he asked for an attorney, at which point the interview was terminated. We conclude, therefore, that Weisgerber’s testimony about the defendant’s demeanor when Weisgerber said that he believed that the defendant was guilty was not inadmissible under Plourde.
We next consider whether Weisgerber’s testimony that the defendant had refused to provide any more information about the murder to the police until he spoke with an attorney violated Doyle. As we have indicated, although the trial court had ruled that Weisgerber would not be permitted to give this testimony, it concluded that the testimony did not violate the defendant’s constitutional rights because it was inadvertent, brief, isolated and had not prejudiced the defendant.
This court held in
State
v.
Hull,
Finally, we address the defendant’s claim that the prosecutor violated
Doyle
when he commented on the defendant’s silence during closing arguments. We conclude that the prosecutor did not violate
Doyle
by stating “isn’t it interesting that [the defendant] doesn’t want to talk about where he was on the night [of the] murder nor what he did” because, as we have already concluded, the defendant had not invoked his constitutional right to remain silent before stating that he did not want to provide details about the night of the murder. Because the defendant chose to talk to the police, any statements that he made properly could be used against him. See
State
v.
Talton,
supra,
IV
Lastly, we address the defendant’s claim that the trial court inadequately instructed the jury regarding the credibility of Gagliardi’s testimony. Specifically, he claims that the trial court should have given the cautionary instruction for jailhouse informants, as required by
State
v.
Patterson,
*755 The following additional facts are relevant to our resolution of this claim. Gagliardi testified at trial that, after she was arrested for drug offenses as the result of the search of the defendant’s apartment, the Norwalk police interviewed her at the Mamaroneck police station. She gave two statements to the police that night. In the first statement, Gagliardi told police that the defendant had been angry because he believed that the victim had stolen his bracelet, that the defendant and the victim had left the defendant’s apartment together on the night of the murder, that the victim never returned to the apartment and that Gagliardi previously had found a gun in the defendant’s jacket. After a break, the police informed Gagliardi that the defendant was not taking responsibility for the drugs that had been seized from his apartment. Gagliardi testified that this upset her and, because she was upset, she gave a second statement indicating that the defendant had told her that he had shot the victim and that the defendant had asked her to provide an alibi. Gagliardi testified that she had received no benefit from the state in exchange for her testimony. She also testified that the drug charges against her had been reduced to misdemeanor charges, that she had served no time in jail 30 and that she was not testifying at trial because the charges had been reduced to a misdemeanor. She further testified that she was not on probation and that, if she had not testified at the defendant’s trial, there would have been no danger that the New York authorities would attempt to imprison her on the drug charges.
The defendant submitted a request to charge requesting that the trial court give a special credibility instruction regarding Gagliardi’s testimony.
31
As legal authority for the charge, the defendant stated: “The
*756
charge is a compilation of the motive and accomplice charges approvingly cited in [D. Borden & L. Orland, 5 Connecticut Practice Series: Criminal Jury Instructions (4th Ed. 2007) § 3.10, pp. 192-93], and a number of Connecticut cases as follows:
State
v.
Cooper,
The trial court specifically instructed the jury that Gagliardi was an informing witness and that the jury could consider whether she had motives for testifying other than truthfully. 32 It did not instruct the jury that *757 Gagliardi’s testimony must be viewed with “particular scrutiny and weighed . . . with greater care than the testimony of an ordinary witness,” as requested by the defendant.
The defendant now claims that he was entitled to a special credibility instruction in accordance with
State
v.
Patterson,
supra,
The judgment is affirmed.
In this opinion the other justices concurred.
Notes
The defendant appealed directly to this court pursuant to General Statutes § 51-199 (b) (3).
The fourth amendment to the United States constitution provides: “The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.”
Article first, § 7, of the Connecticut constitution provides: “The people shall be secure in their persons, houses, papers and possessions from unreasonable searches or seizures; and no warrant to search any place, or to seize any person or things, shall issue without describing them as nearly as may be, nor without probable cause supported by oath or affirmation.”
The fifth amendment to the United States constitution provides in relevant part that “[n]o person . . . shall be compelled in any criminal case to be a witness against himself . . . .”
Weisgerber testified that he and Chrzanowski were in the kitchen of the apartment while the Mamaroneck police conducted the search. Although Holland testified that Weisgerber and Chrzanowski remained outside the apartment, we assume for purposes of this opinion that they were inside the apartment during part of the search.
The record is unclear as to when the cell phone had been seized from the car and who had seized it. Weisgerber testified, however, that he believed that the cell phone was still on the front seat of the vehicle when it was brought to the Mamaroneck police station.
The trial court did not rule explicitly on the question of whether the defendant had a reasonable expectation of privacy in his cell phone or its contents, but implicitly concluded that he did when the court concluded that the cell phone was covered by the search warrant.
The United States Supreme Court has held that the fact that a defendant had a possessory interest in an item that was sufficient to prove a possessory offense is not necessarily sufficient to establish that the defendant had a reasonable expectation of privacy in the item. See
United States
v.
Salvucci,
supra,

United States
v.
Zavala,

Quon
v.
Arch Wireless Operating Co.,
Before this court’s decision in
Miller,
the United States Supreme Court had concluded in
Chambers v. Maroney,
See
D’Antorio
v.
State,
Lustig, Gambino
and
Byars
involved the so-called “ ‘silver platter’ ” doctrine. See
United States
v.
Janis,
A number of state courts have reached this conclusion. See
State
v.
Cauley,
supra,
Indeed, if the Norwalk police had intended to obtain the cell phone, they could have asked the Mamaroneck police to seize it from the defendant’s automobile when he was arrested.
Under federal constitutional law, when an occupant has been arrested and there is reason to believe that the automobile contains evidence related to the offense of arrest, a search of the automobile is valid under the search incident to arrest exception. See
Arizona
v.
Gant,
A number of courts have analogized cell phones to closed containers and concluded that a search of their contents is, therefore, valid under the automobile exception or the exception for a search incident to arrest. See
United States
v.
Rocha,
United States District Court, Docket No. 06-40057-01-RDR (D. Kan. October 2, 2008) (automobile exception);
United States
v.
James,
United States District Court, Docket No. 1:06CR134 CDP,
In
United States
v.
Murphy,
“Finally, [the defendant’s] argument must be rejected because to require police officers to ascertain the storage capacity of a cell phone before conducting a search would simply be an unworkable and unreasonable rule. It is unlikely that police officers would have any way of knowing whether the text messages and other information stored on a cell phone will be preserved or be automatically deleted simply by looking at the cell phone. . . . Rather, it is very likely that in the time it takes for officers to ascertain *735 a cell phone’s particular storage capacity, the information stored therein could be permanently lost.” (Citation omitted.) Id., 411.
Moreover, we do not believe that the New York Court of Appeals would be persuaded by the reasoning of the court in
Park
that a search of the contents of a cell phone is not valid under the automobile exception because the search is not necessary to preserve the safety of police officers or to prevent the concealment or destruction of evidence, because the New York court has held that a primary justification for the exception is the reduced expectation of privacy in automobiles. See
People
v.
Blasich,
supra,
Indeed, the trial court expressly found that “[t]he [cell] phone was seized base[d] upon the experience of the police that it contained evidence of drug activity.” The defendant contends that this finding was clearly erroneous because the Mamaroneck “police never obtained search warrants for cell phones but automatically seized them in narcotics cases and searched them in the hopes that it would help in their investigations.” Even if we assume that the police are required to specify cell phones when requesting authority to seize records of drug activities, however, the fact that the Mamaroneck police customarily did not ask for such authority does not mean that they would not receive it if they asked for it based on their experience that cell phones are likely to contain such records. Holland testified at the suppression hearing that the police customarily seized cell phones to determine whether calls had been made to persons who were known to be drug users or drug dealers. We conclude, therefore, that the trial court’s finding was supported by the record.
Gentile testified at the suppression hearing that these events occurred in December, 2002. She also testified, however, that they occurred before she met with Norwalk police in February, 2002. At trial, Gentile testified that the events occurred in December, 2001.
The trial court charged the jury that “[t]he evidence offered by the state of prior acts of misconduct of the defendant is not being admitted to prove the bad character of the defendant or the defendant’s tendency to commit *739 criminal acts. Such evidence is being admitted solely to show or establish the identity of the person who committed the crime which is the subject of this trial.
“You may not consider such evidence as establishing a predisposition on the part of the defendant to commit any of the crimes charged or to demonstrate a criminal propensity. You may consider such evidence if you believe it and further find it logically, rationally, and conclusively supports the issue for which it is being offered by the state, but only as it may bear here on the issue of identity. You have [to] independently assess the similarities between the offense involving . . . Gentile and this offense.
“On the other hand, if you do not believe such evidence or even if you do, [if] the offenses are not similar in their circumstances, if you find that there’s not logically, rationally, and conclusively support [for the] issue for which it is being offered by the state, namely, identity of the person who committed the matter, the homicide of [the victim] . . . [t]hen you may not consider that particular testimony of . . . Gentile for any purpose.
“You may not consider evidence of prior misconduct, except for the limited purpose of . . . attempting to prove identity, because it may predispose your mind uncritically to believe that the defendant [may be] guilty of the offense here charged, merely because of the alleged prior misconduct. So for this reason, you may consider the . . . Gentile evidence only on the issue, that particular portion of her testimony, only as it bears on . . . identity and for no other purpose.”
Conn. Code Evid. § 4-5 (b) provides in relevant part: “Evidence of other crimes, wrongs or acts of a person is admissible ... to prove . . . identity • • • •”
See Conn. Code Evid. § 4-5 (a) (“[ejvidence of other crimes, wrongs or acts of a person is inadmissible to prove the bad character or criminal tendencies of that person”).
In Missouri, the admission of propensity evidence has been found to violate the defendant’s state constitutional right to be tried for the offense for which he was indicted.
State
v.
Vorhees,
supra,
See
Miranda
v.
Arizona,
The trial court later issued a written memorandum of decision explaining its decision. The defendant does not challenge this ruling on appeal.
Defense counsel expressly stated that she did not object to Weisgerber’s testimony that, after the defendant told Weisgerber that his question whether the defendant had been in Norwalk with the victim on the night of the murder was a very good one, the defendant stated that he was not going to discuss the crime scene. The defendant’s objection to that testimony was, therefore, waived.
The defendant cites several cases for the proposition that a defendant may reassert his right to remain silent after waiving it by refusing to respond to any more questions. He also cites several cases for the proposition that, when a defendant answers general questions by the police but refuses to discuss the crime, he has invoked his right to remain silent. Those cases *751 are inapposite in the present case because the defendant did not refuse to answer questions about the crime until he asked for an attorney, at which point the police ended the interview.
Under
Golding,
“a defendant can prevail on a claim of constitutional error not preserved at trial only if all of the following conditions are met: (1) the record is adequate to review the alleged claim of error; (2) the claim is of constitutional magnitude alleging the violation of a fundamental right; (3) the alleged constitutional violation clearly exists and clearly deprived the defendant of a fair trial; and (4) if subject to harmless error analysis, the state has failed to demonstrate harmlessness of the alleged constitutional violation beyond a reasonable doubt. In the absence of any one of these conditions, the defendant’s claim will fail.”
State
v.
Golding,
supra,
During argument on the defendant’s motion for amistrial, the prosecutor explained to the trial court that he had had only about ten minutes to review the court's rulings on the police report with Weisgerber before he testified. When the prosecutor asked Weisgerber during his testimony why the defendant had not been willing to divulge what he knew about the murder, he expected that Weisgerber would testify that the defendant did not want to *754 talk because the police were not going to release him that night, not that he wanted to speak with an attorney first.
Gagliardi could not remember if she had pleaded guilty to the misdemeanor drug charges.
The defendant submitted the following request to charge: “In this matter it can clearly be said that the credibility of . . . Gagliardi, state’s informant, is a pivotal issue for you to consider.
*756 “An informer is one who claims to have heard another defendant make an admission about his case.
“In considering and weighing the testimony of an informer, you will test it by those rules of probability or improbability by which human conduct and the motives impelling or influencing people to do certain things are usually applied. You may consider his/her appearance and demeanor as a witness, the reasons she gave for telling the story to the state authorities, and among these tests, to consider whether any motive has appeared or any reason is apparent why she should seek to fasten so grave a crime upon the accused, if her story is untrue. The presence or absence of a motive is often an important factor to consider in a determination of the truth or falsity of a story. You may consider any promises that were made by a person in authority and the circumstances under which the informer’s statement was made to any person in authority. You can also consider whether [her] complaint is retaliatory in nature and a response to her position that [the defendant] refused to exonerate her for illegally possessing narcotics.
“In other words, the testimony of an informer who provides evidence against a defendant must be reviewed with particular scrutiny and weighed by you with greater care than the testimony of an ordinary witness.
“Whether the informer’s testimony has been affected by interest or prejudice against the defendant is exclusively for you to determine.”
The trial court instructed the jury that “[a]n informing witness is one who claims to have heard the defendant make an admission about his case. In this case you may consider whether . . . Gagliardi was an informing witness and whether she had any special interest in the matter.
“In considering and weighing the testimony of an informing witness, you will test it by those rules of probability and improbability by which human conduct in the motives impelling or influencing people to do certain things are usually applied. You may consider her appearance [and] demeanor as a witness, the reasons she gave for telling what she did to the state authorities, and among these tests to consider whether any motive has appeared for her to inform the authorities other than truthfully. It is for you to decide *757 what credibility you will give . . . Gagliardi. Like all other questions of credibility, this is a question you must decide based on all the evidence presented to you.”

v.
Cooper,

Even on appeal, the defendant has cited no cases in which
Patterson
has been applied to the testimony of a witness who had not been incarcerated with the defendant. Rather, he contends that we should expand

to apply to any witness who may have received a promise from the police or the prosecutor in exchange for his or her testimony. In
