delivered the opinion of the court:
Defendant, Mary Braggs, was charged in the circuit court of Cook County with two counts of first degree murder for the deaths of Connie Hall and Donald Rudolph. After refusing to conduct a hearing on defendant’s pending motion to suppress statements, the circuit court determined that defendant was unfit to stand trial due to the severity of her mental retardation. The court thereafter conducted a discharge hearing, found the State’s evidence sufficient to establish defendant’s guilt beyond a reasonable doubt, and remanded defendant to the Department of Mental Health and Developmental Disabilities for a period of five years. Defendant appealed.
The appellate court reversed and remanded. People v. Braggs,
On remand, the circuit court conducted a hearing on defendant’s motion to suppress, hearing testimony from the investigating detective, a psychiatrist, a clinical psychologist, and an assistant State’s Attorney who had interviewed defendant after she was formally arrested. The court ultimately ruled defendant was not competent to waive her Miranda rights, and consequently granted defendant’s motion with respect to statements made to the assistant State’s Attorney after defendant’s arrest. However, the court did not suppress an inculpatory statement defendant allegedly made to detectives shortly before she was formally arrested, concluding that defendant was not then in custody, there was no evidence of police coercion or misconduct, and the statement was, therefore, admissible. The circuit court determined that a new discharge hearing was not necessary and reinstated the original order committing defendant to the Department of Mental Health. Defendant again appealed.
The appellate court reversed and remanded, stating:
“[W]hen the trial court ruled that Braggs’ statements to the police were admissible because she was not in custody and Miranda was inapplicable, it was in error. Likewise, the court’s ruling that, in the absence of police coercion or the defendant being in custody, the fact that Braggs was mentally handicapped was to be considered only as to the weight to be given her statements and not as to whether those statements were inadmissible, was in error. The court should have considered whether Braggs’ statement to the detectives was voluntary in a state-law sense based upon the totality of the circumstances. [Citation.] One of the factors that the court should have considered was whether Braggs’ mental retardation deprived her of ‘the capacity to understand the meaning and effect of the confession.’ [Citation.] This is particularly important in the present case, where the trial court found the defendant was incapable of waiving her rights under Miranda due to her diminished mental capacity.”335 Ill. App. 3d 52 , 65.
The appellate court remanded the cause for a new hearing on defendant’s motion to suppress, directing the circuit court to conduct a new discharge hearing thereafter.
We granted the State’s petition for leave to appeal (177 Ill. 2d R. 315), and we now affirm, with modification, the judgment of the appellate court. We begin with a recitation of the evidence adduced at the suppression hearing.
Chicago police detective Edward Winstead testified that he investigated the deaths of Donald Rudolph and Connie Hall. The victims’ bodies were both found in a first-floor apartment located on South Prairie Avenue in Chicago on April 28, 1993. Although officers initially thought that Rudolph had been beaten to death, it was later determined that Rudolph died as a result of strangulation. Hall died as a result of multiple stab wounds. During the course of the investigation, Winstead began looking for defendant.
On May 7, 1993, Survilla Cameron contacted Win-stead and informed him that defendant lived with her. Cameron represented herself to be defendant’s sister and guardian; however, Winstead admitted he never saw any documentation to substantiate Cameron’s claim. After Cameron indicated that Winstead could speak with defendant, Winstead transported defendant and Cameron to Area One and questioned her. Prior to questioning, Cameron informed Winstead that defendant was “mentally incompetent.” Winstead admitted one could “clearly see that she was mentally deficient.” Cameron agreed to help Winstead in his interrogation of defendant, but cautioned him that defendant was “slow.” Winstead did not advise defendant of her Miranda rights. The interrogation took place in an interview room with another detective present.
Winstead testified he had difficulty communicating with defendant in that “sometimes she wouldn’t answer questions,” and other times she was “very slow in answering.” In Winstead’s own words: “She would be very slow in answering. And her sister would then kind of repeat the question or if Mary Braggs seemed to be paying attention to me she would then answer to her sister.” If defendant responded, she would generally direct her answers to Cameron, and Cameron would then “tell [Winstead] what [defendant] was saying.” However, Winstead testified he could hear defendant as she spoke. During the interrogation, Cameron acted as an intermediary for Winstead. Defendant’s answers were responsive to Winstead’s questions in the sense that defendant would respond to questions repeated by Cameron and first posed by Winstead.
Winstead summarized the substance of defendant’s statements from the hour-long interrogation. According to Winstead, defendant told him that she was in the apartment on South Prairie Avenue when two black males came to the door. Defendant overheard an argument and hid in the closet. When she came out, defendant saw Hall dead in the bedroom. Defendant said Hall had been stabbed and was wearing white. Defendant said Rudolph was in the front room. He had been hit in the head with a wrench and had been strangled to death. Win-stead testified that defendant’s description was “very accurate as to how the victims died and where they were found.” Following the interrogation, Winstead took defendant and Cameron home.
On the morning of May 9, Winstead again questioned defendant, this time at Cameron’s apartment. As in all of the interviews, Cameron was present. Detective James Redmond was also present. Winstead said defendant was still very slow in answering questions, or she might not answer at all, but during this second interrogation, she at least spoke directly to him most of the time. Winstead testified he went to question defendant, a mere two days after the first interrogation, “to see if [he] could get a little bit more information, if she recalled more about the two black males who came to the door and the argument.” Winstead testified that defendant told him one of the men was named Ron and he was a friend of Cleo. Defendant described the other man as a tall black male. Winstead testified that the investigation revealed Ron Thomas was an acquaintance of Cleo and the victims, and when Winstead located him he was with a tall black male named Mike.
Later that same afternoon, Winstead picked up defendant and Cameron and took them to Area One. Win-stead spoke to defendant in an interview room. He indicated, as previously, it took defendant a long time to answer questions. “Often times [sic] she would put her head down and say T don’t know.’ ” Winstead showed defendant photographs of Ron Thomas and Mike. Defendant quickly identified the photograph of Mike as being the tall black male. Winstead said she was at first uncertain of the identity of Ron Thomas, then she positively identified him. Winstead testified that when he informed defendant the men were at the police station, defendant changed her story. Defendant then said that these were not the two men who came to the apartment and that it was two different men. Defendant reiterated that two men came to the door and she hid in the closet.
Winstead testified that on that same afternoon he took defendant and Cameron to the scene of the murders. Defendant pointed out where the two bodies were found. Winstead testified that her account was consistent with where the bodies were found by the police. Defendant then showed Winstead the closet where she hid. Win-stead testified he examined the closet and defendant “couldn’t have possibly fit in there.” Winstead then took defendant and Cameron home, having questioned defendant at three different locations over the course of the day.
On May 12, Winstead transported defendant and Cameron to the polygraph unit of the Chicago police department. Although defendant was cooperative, the polygraph examination was inconclusive because defendant did not register enough emotion. Again, defendant was returned to Cameron’s apartment. Cameron and defendant subsequently changed residences.
On June 25, 1993, Winstead picked up defendant and Cameron from their new apartment and again took them to Area One for questioning. Prior to the questioning, Winstead informed Cameron that the police were looking at defendant as a potential suspect. Despite the State’s representation otherwise, the record is silent as to whether that information was communicated to defendant. Winstead, another detective, defendant, and Cameron were present in the interview room. Winstead advised defendant of her Miranda warnings from a standard form without additional explanation. Defendant made no verbal response; she merely nodded her head in an affirmative manner. Although Winstead could not remember her exact words, he recalled that Cameron said something to the effect of: “he’s telling you that you don’t have to talk to me and that you’re not going to be in trouble or something.” Defendant nodded her head in agreement and “seemed to understand what her sister was saying.” Defendant never verbally indicated that she understood, and she did not sign a waiver form. Indeed, it is unclear to what extent defendant ever responded to, or communicated with Winstead. He acknowledged that Cameron “initially” acted as an “interpreter,” and it is obvious from the foregoing testimony that she was still acting in that capacity on June 25, 1993, despite Win-stead’s suggestion to the contrary: “After a while, after I talked to [defendant] somewhat, I could begin to understand or she’d answer me or she wouldn’t.” The record does not indicate whether Winstead’s questions to defendant were suggestive or leading, or whether they called for a narrative response.
Although the transcript of the suppression hearing does not reveal the substance of statements defendant made during the June 25 interview, the testimony of another detective from the discharge hearing indicated that defendant said she and Connie Hall were in an apartment together on April 28, 1993, when Donald Rudolph returned. Rudolph was drunk and struck both defendant and Hall. Defendant then knocked Rudolph down and he struck his head. Hall became upset, accusing defendant of killing Rudolph, and defendant then stabbed Hall a number of times in her upper body. Following the hour-long interview, defendant was placed under arrest. An assistant State’s Attorney arrived at the police station and again advised defendant of her Miranda warnings.
Dr. Philip Pan, a psychiatrist, testified for the defense. On May 16, 1996, Pan diagnosed the defendant as having moderate mental retardation and determined defendant was unfit to stand trial. He noted that four other psychiatrists had reached the same conclusion. In 1996, Pan concluded it was not likely that defendant could be restored to fitness anytime in the near future. On August 31, 1999, Pan again evaluated defendant. Dr. Pan testified that defendant was unfit for trial and would not become fit in the future. Pan also rendered his opinion that defendant was incapable of understanding Miranda warnings.
By way of explanation, Dr. Pan testified that defendant could give simple answers to questions she understood, but she was not capable of abstract thinking. Although she knew she was born in 1941, defendant told Dr. Pan, in the course of his 1999 interview, that she was 29 years old. Her thinking was “idiosyncratic,” meaning that she was often “not on the same page” as the person questioning her. She would frequently answer questions in a completely irrelevant manner. When asked the meaning of her right to remain silent, she responded that she already had an attorney. When Pan asked her what it meant that anything she said could be used against her in a court of law, she responded, “he know I didn’t do those two crimes. That is something I didn’t do.”
Dr. Linda Wertzel, a clinical psychologist, also testified for the defense. Wertzel had examined defendant in 1994 and testified to her findings. Wertzel concluded that defendant was mentally retarded with an IQ of 54. Wertzel described her observations of defendant at that time:
“[S]he was flat and passive, kind of emotionally blunted, no affect. She was overweight. She was — her clothing was dirty. Her hygiene was very poor. She was picking at her skin and nails and nose and ears. She was nonspontaneous in her speech.”
Defendant could provide only “simple answers to direct questions and really did not provide a narrative of information.” She stated her age to be 29. Testing revealed that defendant functioned, mathematically, at a kindergarten level. Defendant was unsure if she had ever gone to school. She could not read or write.
Wertzel administered a test designed to measure a person’s ability to express thoughts accurately and coherently and to comprehend what other people say. She determined that defendant could only express herself at a “very simple childish level” and she could not comprehend more than a one-step command. Wertzel said the test involved asking the subject to touch colored shapes in sequence. Wertzel first asked defendant to touch a red square (one-step command), then asked her to touch a red square and a yellow circle in sequence (two-step command). Defendant could not get beyond the one-step command. Defendant was inconsistent in her ability to identify shapes correctly. She displayed impairment on both motor speed and motor dexterity tests. She could not accurately draw and number the face of a clock.
When asked the meaning of various Miranda warnings, defendant either said she did not know or she offered an irrelevant or inappropriate response. Eventually, defendant became frustrated and the interview was terminated. As a result of her 1994 examination of defendant, Wertzel concluded that defendant was illiterate, mentally retarded, “only minimally able to care for her basic daily needs, her comprehension of her current circumstances was marginal, and she was unable to understand her Miranda rights.”
Wertzel examined defendant again in October 1999 and concluded she remained unable to understand her Miranda warnings. Dr. Wertzel testified that defendant’s behavior was “pretty similar” to her first encounter with defendant. Defendant “acted as though she had only been in jail for about a week.” She identified Kennedy as president of the United States. Wertzel administered the Peabody Picture Vocabulary Test, in which the subject is shown a picture and is asked to name activities or pastimes represented therein. Defendant scored the age equivalent of a five-year-old. After her 1999 examination of defendant, Wertzel again concluded it was “highly unlikely” that defendant ever had the ability to comprehend or waive Miranda rights.
Wertzel described defendant as “sort of like a child, *** unsure of what is real and what is imagined, what is an actual memory, what is told to them.” Moreover, she stated that defendant does not tolerate stress very well and is “suggestible.” Wertzel described more than one instance where she was able to lead defendant in the questioning to get the information desired.
In rebuttal, the State called Assistant State’s Attorney Stan Gonsalves. Gonsalves testified he went to Area One on June 25, 1993, to interview defendant. Prior to meeting defendant, detectives told Gonsalves defendant was “a little slow.” Gonsalves advised defendant of her Miranda warnings. Gonsalves said defendant was “just quiet at that point.” Defendant did not respond verbally when she was asked if she understood her rights. Defendant nodded her head affirmatively after Gonsalves finished giving her the Miranda warnings. Cameron was in the room, but did not say anything. Gonsalves testified that defendant was responsive to his questions during the interrogation, but he conceded that communicating with defendant was “difficult” and “slow.” The record does not indicate whether Gonsalves’ questions to defendant were suggestive or leading, or whether they called for a narrative response.
After hearing testimony in this matter, the circuit court rendered its ruling. The judge’s initial statements indicate that he believed the issue in this case was the same as that presented in People v. Bernasco,
Citing Colorado v. Connelly,
The court concluded that defendant was in custody following her statement to the Winstead and she did not knowingly and intelligently waive her Miranda rights. In so ruling, the court relied upon the uncontroverted testimony of Pan and Wertzel, and that of law enforcement personnel who observed defendant’s actions and demeanor during periods of interrogation. The court specifically mentioned “the testimony of Winstead about how she acted and [Assistant] State’s Attorney Gonsalves that she did not respond verbally [when] given her rights. She merely stood silent.”
Based upon the uncontested testimony of the witnesses, the court suppressed the statement defendant made to Assistant State’s Attorney Gonsalves following her arrest. The court, however, denied defendant’s motion with respect to any statements made before defendant was in custody.
On appeal, the State posits a single issue: whether defendant’s final “statement” or “confession” to Win-stead — which, on the basis of the trial court’s ruling, the State assumes was noncustodial — was “constitutionally voluntary because it was given without police coercion” — a second assumption based upon conclusions the trial court drew from undisputed facts. Defendant continues to argue, inter alia, that defendant was in custody when she gave the allegedly inculpatory statement to Detective Winstead and that she did not effectively waive her Miranda rights. The State disputes the former contention, but not the latter.
We begin our analysis by identifying the relevant standard of review and the burden of proof. A court of review will accord great deference to the trial court’s factual findings, and will reverse those findings only if they are against the manifest weight of the evidence; however, the court will review de novo the ultimate question posed by the legal challenge to a trial court’s ruling on a motion to suppress. People v. Sorenson,
In this case, the trial court determined that defendant was unable to effectively waive her Miranda rights, based upon the unrefuted testimony of the doctors who had examined her and law enforcement personnel who observed her actions and demeanor. Consequently, the trial court granted the defendant’s motion to suppress as to statements allegedly made by defendant after she was formally arrested. The court denied defendant’s motion with respect to her earlier statement to Winstead only because the court believed she was not “in custody” for purposes of Miranda at that time. Since defendant continues to argue that she was in custody when she was interrogated by Winstead at the police station on June 25, 1993, we first address the custodial issue.
The determination of whether a defendant is “in custody” for Miranda purposes involves “[t]wo discrete inquiries ***: first, what were the circumstances surrounding the interrogation; and second, given those circumstances, would a reasonable person have felt he or she was not at liberty to terminate the interrogation and leave.” Thompson v. Keohane,
When examining the circumstances of interrogation, the following factors have been found relevant in determining whether a statement was made in a custodial setting: the location, time, length, mood, and mode of the interrogation, the number of police officers present, the presence or absence of the family and friends of the accused, any indicia of formal arrest, and the age, intelligence, and mental makeup of the accused. See People v. Lucas,
As we consider the age, intelligence, and mental makeup of the accused — and an investigating officer’s awareness and exploitation of those characteristics — in our examination of the circumstances surrounding the interrogation, so those factors are analytically intertwined with the reasonable-person prong of the custodial question. Indeed, other courts have incorporated these factors into the reasonable-person standard itself in varied circumstances involving investigatory interaction between the police and citizens. See United States v. Zapata,
The justification for incorporating general and readily discernible characteristics of the subject-actor into the reasonable-person standard logically must apply in this situation as well. If, as is the case, we are concerned with what a reasonable person “in the defendant’s shoes” (see Lucas,
Recognizing this principle, the Ninth Circuit Court of Appeals has suggested the applicable standard should indeed be modified in this context, where a juvenile is concerned, to reflect what a reasonable juvenile would have thought in defendant’s position. Alvarado v. Hickman,
“ ‘Given these facts, a reasonable juvenile in E.L.’s position would not have believed that the officers had curtailed his freedom of movement to a degree associated with formal arrest.’ ” (Emphasis in original.) Alvarado,316 F.3d at 848 , quoting Erving L.,147 F.3d at 1248 .
The Alvarado court then observed, “When we survey the landscape of state court decisions, we note that every jurisdiction that has squarely addressed the issue has ruled that juvenile status is relevant to the ‘in custody’ determination, either as a factor in the totality of circumstances test, or by way of modification to the reasonable person standard.” (Emphasis added.) Alvarado,
The same rationale that requires modification of the reasonable person standard to take into account the general characteristics of juveniles also militates in favor of such a modification where the mentally retarded are concerned. “[Mjental retardation may have a significant impact on an individual who finds himself involved with the criminal justice system, particularly in the context of confessions and interrogations. *** Many mentally retarded people may be less likely to withstand police coercion or pressure due to their limited communication skills, their predisposition to answer questions so as to please the questioner rather than to answer the question accurately, and their tendency to be submissive.” L. Entzeroth, Putting the Mentally Retarded Criminal Defendant to Death: Charting the Development of a National Consensus to Exempt the Mentally Retarded from the Death Penalty, 52 Ala. L. Rev. 911, 917 (2001). See also P. Hourihan, Earl Washington’s Confession: Mental Retardation and the Law of Confessions, 81 Va. L. Rev. 1471, 1473 (1995) (“Mentally retarded persons are more susceptible to coercion, more likely to confess falsely, and less likely to understand their rights than people of normal intellectual ability”). Just as they are more susceptible to police coercion during a custodial interrogation, the mentally retarded are also more susceptible to the impression that they are, in fact, in custody in the first instance. The circumstances of the instant case amply demonstrate the point.
Including the initial interrogation of June 25, 1993, defendant was questioned by police six times before she was formally arrested: four times at a police facility, once at her home and once at the scene of the crime. The police enlisted the aid and consent of Cameron — who apparently represented herself to be defendant’s sister and legal guardian — in order to question defendant. Cameron acted as a translator of sorts and actually facilitated the police interrogation. Her role in the process of interrogation is not what we characterize as that of a family member concerned with defendant’s welfare. It is not evident from the record that defendant ever verbally assented to police interrogation. On every occasion that she was questioned outside her home, the police transported defendant. Two detectives were always present during the interrogations. Although it is not clear from the record whether defendant was present when Winstead advised Cameron that defendant was a suspect, even a mentally retarded suspect might well have regarded herself as such after Winstead had expressed disbelief of her version of events and had asked her to take a polygraph examination. We also note that Winstead for the first time read defendant her Miranda rights on June 25, something he had not done in previous encounters. We have no doubt whatsoever that a reasonable person with defendant’s mental capacity would have believed he or she was in custody and not free to leave the police station.
In fact, our research has disclosed a case involving similar circumstances, a person of apparently normal intelligence, and a determination that the interrogation was custodial. In United States v. Wauneka,
Like Wauneka, the defendant in this case was repeatedly taken by officers to a law enforcement facility and questioned. As in Wauneka, the instant defendant was never told she could leave the station when she wished; she was taken home by the police when they were finished with her. By the time of the encounter on June 25, the atmosphere of the interrogation had turned accusatory: defendant had taken a polygraph examination and had been designated a suspect by Winstead. However, defendant, unlike Wauneka, is mentally retarded. She was only at the police station because her purported guardian/sister agreed to police requests that she accompany them there. Her options, no doubt, seemed very limited indeed.
Under the circumstances, a reasonable person with defendant’s mental capacity would not have felt free to leave. In this case, the police knowingly exploited defendant’s mental retardation. While the custody inquiry may not “place upon the police the burden of anticipating the frailties or idiosyncracies of every person whom they question” (Berkemer,
Having determined that Winstead’s interrogation of defendant on June 25 was custodial, we now address the question of whether defendant knowingly and intelligently waived her Miranda rights. Custodial interrogation is, of course, inherently coercive and “ ‘trades on the weakness of individuals.’ ” Dickerson v. United States,
However, evidence of a defendant’s limited mental or intellectual capacity at the time of a confession, alone, does not establish that he or she was incapable of waiving Miranda rights. Limited intellectual capacity is one of several factors to be considered in this regard. People v. Foster,
Nevertheless, “[w]aiver of a constitutional right is valid only if it is clearly established that there was ‘an intentional relinquishment or abandonment of a known right ***.’ ” People v. Johnson,
A valid waiver of Miranda rights must be knowingly and intelligently made. Bernasco,
It is all too obvious, as the trial court concluded, that the defendant in this case did not knowingly and intelligently waive her Miranda rights. The State does not even attempt to argue that point. Winstead advised defendant of her Miranda warnings from a standard form without additional explanation. Defendant made no verbal response; she merely nodded her head in an affirmative manner. Winstead later recalled that Cameron told defendant something to the effect of: “He’s telling you that you don’t have to talk to me and that you’re not going to be in trouble or something.” Defendant nodded her head in agreement and “seemed to understand what her sister was saying.” Defendant never verbally indicated that she understood, and she did not sign a waiver form. Indeed, it is unclear to what extent defendant ever responded to, or communicated with, Winstead. He acknowledged that Cameron “initially” acted as an “interpreter,” and it is obvious from his testimony that she was still acting in that capacity on June 25, 1993, despite Winstead’s suggestion to the contrary: “After a while, after I talked to [defendant] somewhat, I could begin to understand or she’d answer me or she wouldn’t.” That statement is hardly a testament to an acceptable level of communication and understanding between Win-stead and defendant. The record does not indicate whether Winstead’s questions to defendant were suggestive or leading, or whether they called for a narrative response.
Assistant State’s Attorney Gonsalves testified that he advised defendant of her Miranda warnings, and she was “just quiet at that point.” Defendant did not respond verbally when she was asked if she understood her rights. Defendant simply nodded her head affirmatively after Gonsalves finished giving her the Miranda warnings. Cameron was in the room, but did not say anything. Gonsalves testified that defendant was responsive to his questions during the interrogation, but he conceded that communicating with defendant was “difficult” and “slow.” The record does not indicate whether Gonsalves’ questions to defendant were suggestive or leading, or whether they called for a narrative response. It does not appear from the record that defendant had any prior experience with the criminal justice system.
Dr. Philip Pan characterized defendant’s mental impairment as moderate mental retardation. He determined her condition was profound to a degree that she was unfit to stand trial. He noted that four other psychiatrists had reached the same conclusion. Pan rendered his opinion that defendant was incapable of understanding Miranda warnings. He noted that her thinking was “idiosyncratic,” meaning she was often “not on the same page” as the person questioning her. She would frequently answer questions in a completely irrelevant manner.
Dr. Linda Wertzel, a clinical psychologist, examined defendant in 1994 and testified to her findings. Wertzel concluded that defendant was mentally retarded with an IQ of 54. Wertzel stated that defendant could provide only “simple answers to direct questions and really did not provide a narrative of information.” Defendant functioned, mathematically, at a kindergarten level. Defendant was unsure if she had ever gone to school. She could not read or write. Wertzel determined that defendant could only express herself at a “very simple childish level” and she could not comprehend more than a one-step command. Defendant’s comprehension of her circumstances was marginal, and she was unable to understand her Miranda rights.
Wertzel examined defendant again in October of 1999 and concluded defendant remained unable to understand her Miranda warnings. Wertzel then administered the Peabody Picture Vocabulary Test to defendant. Defendant scored the age equivalent of a five-year-old. After her 1999 examination of defendant, Wertzel determined it was “highly unlikely” that defendant ever had the ability to comprehend or waive Miranda rights. Wertzel described defendant as “sort of like a child, *** unsure of what is real and what is imagined, what is an actual memoiy, what is told to them.” Moreover, she stated that defendant does not tolerate stress very well and is “suggestible.” Wertzel described more than one instance where she was able to lead defendant in the questioning to get the response desired.
The uncontroverted testimony in this case demonstrates that defendant did not knowingly and intelligently waive her Miranda rights. No other conclusion is possible based on the evidence adduced at the suppression hearing. Defendant was subjected to repeated interrogation that was actually facilitated by her purported sister/guardian. By repeatedly taking defendant where they wanted, when they wanted, the police reinforced their authority and control over her. Defendant apparently had no prior experience with the criminal justice system. She was clearly a suspect by the time she took a polygraph test and was thereafter questioned on June 25, 1993. The experts who testified were unanimously of the opinion that defendant was incapable of understanding and waiving her Miranda rights. Aside from the State’s testimony regarding defendant’s ambiguous nods, there was no evidence even suggesting that defendant waived her rights. In fact, the minimal level of communication between law enforcement officials and the defendant throughout the investigation of this case is a matter of great concern to this court and should have been to the officers involved, who proceeded to repeatedly question defendant despite her obvious impairment and vulnerability. We note that the degree of defendant’s mental impairment is comparable to that of the defendants in Bernasco and People v. Robinson,
It has been said that “a system of criminal law enforcement which comes to depend on the ‘confession’ will, in the long run, be less reliable and more subject to abuses than a system which depends on extrinsic evidence independently secured through skillful investigation.” Escobedo v. Illinois,
Both confessions defendant allegedly gave on June 25, 1993, were made under circumstances custodial in nature. As defendant was incapable of knowingly and intelligently waiving her Miranda rights, both statements should have been suppressed. We express no opinion regarding the admissibility of statements defendant may have made prior to that date. The State’s argument on appeal concerns only defendant’s “confession to the detectives.” We, therefore, affirm the judgment of the appellate court insofar as we reverse and remand for further suppression proceedings and a new discharge hearing. We modify the appellate court’s judgment to the extent that we limit the scope of any further suppression proceedings to statements defendant may have made prior to June 25, 1993.
Given our disposition, we need not reach the issue upon which the appellate court disposed of this case. We may affirm the result below on any basis that is supported by the record. People v. Huff,
For the reasons stated, we affirm the judgment of the appellate court as modified and remand to the circuit court for further proceedings consistent with this opinion.
Affirmed as modified; cause remanded.
