[¶ 1] Nаthaneal K. Nightingale appeals from a judgment of conviction of one count of murder, 17-AM.R.S. § 201(1)(A) (2011), and one count of manslaughter (Class A), 17-A M.R.S. § 203(1)(A) (2011), entered in the trial court (Anderson, J.) following a jury trial. Nightingale argues that the court erred in denying his motion to suppress a confession, other statements, and physical evidence found as a result of the statements. We affirm the judgment.
I. FACTS AND PROCEDURAL HISTORY
[¶ 2] Michael L. Miller and Valerie J. Miller were shot and killed in their home in Webster Plantation on November 28, 2009. At some point in the investigation, it was determined that Nightingale was either the last person or one of the last persons to be at the Millers’ home. The police cоntacted Nightingale to see whether he would be willing to take a polygraph test after Nightingale told the police that a woman came to the Millers’ house just as he was leaving. Nightingale agreed and drove himself to the Criminal Investigation Division located at the Dorothea Dix building on Hogan Road in Bangor, arriving at the scheduled time on December 11, 2009. The room in which the examination was conducted was about ten by twelve feet, with a polygraph chair, additional chairs for the two detectives who participated, and a table for the equipment. To exit the room, Nightingale would have needed to walk past one or both officers who participated.
[¶ 3] Maine State Police Supervisor Warren Ferland conducted the polygraph examination. The entire process lasted just over nine hours and was captured on video files that were admitted at the motion hearing.
[¶ 4] The process was divided into three sections. The first was the pre-test interview, which started at about 10:30 a.m. The first part is designed to determine whether the person being tеsted is suitable for testing based on his or her medical and psychological condition. The second part, consisting of polygraph data collection, started at 12:42 p.m. and lasted until 1:42 p.m. The third section was the post-test interview, which began at 2:20 p.m., after the first extended break. At about 3:40 p.m., Ferland was joined by Detective Dale Keegan. They took a second break at 4:30 p.m. When Nightingale returned, Ferland offered him a drink, which he declined. The third break was at about 6:15 p.m.
[¶ 5] During the third break, they gave Nightingale a sandwich and then resumed at about 7:10 p.m. Ferland testified that he “went over Miranda again” with Nightingale. Again, Nightingale told Ferland and Keegan that he understood his rights and wanted to continue to talk. Keegan testified that he and Ferland pointed out the inconsistencies in Nightingale’s story. Ferland testified that just before 7:35 p.m., he told Nightingale that he knew that Nightingale “was the one who actually took the lives of Mr. and Mrs. Miller. And at that point is when he told me that he thought that, you know, he should have an attorney.” Ferland then terminated the interview. Ferland testified that Nightingale said that he wanted to talk with some family members and would be back in contact with Keegan the next day.
[¶ 6] Ferland testified that he told Nightingale “throughout the process several times” that he was “not under arrest, he was free to leave at any time, he could stop the process any time he wanted to and, you know, that he was going to be going home that night.” The two officers were not dressed in uniform and were not visibly armed. There was no confrontation or raised voices, and there were no threats or promises.
[¶ 7] During the post-test interview, Ferland and Keegan suggested to Nightingale that they potentially had satellite photography of his car at the Millers’ home; had DNA test results showing that Nightingale’s DNA was on a doorknob and a locking mechanism at the Millers’ home, which was significant because it appeared that the last person out had locked the door; had found flakes of Nightingale’s skin on the Millers’ bodies; and had recovered fingerprint or DNA evidence on money that the detectives told Nightingale they had seized from his father. These were “realistic bluffs” and untrue.
[¶ 8] Approximately three hours after the nine-hour interrogation ended, law enforcement received information that Nightingale had confessed to his mother and a friend. Keegan testified that at about 10:30 p.m., his supervisor asked him to check on Nightingale’s welfare because Nightingale’s friend “was concerned that he may be suicidal.” Keegan called Nightingale on the telephone. According to Keegan, Nightingale seemed “very calm ... too calm, if you will,” and told Keegan that he would meet with him the next day. In spite of this, Keegan and Detective Darrin Crane went to and entered Nightingale’s residence, which was his mother’s home, in order to initiate contact with him again. A third officer remained outside. Although there was testimony at the hearing that Nightingale had ingested several crushed Percocet pills, a narcotic, after the nine-hour interrogation, Nightingale’s ability to comprehend the subsequent interrogation at his residence is not at issue in this appeal. An audio recording and a
[¶ 9] Keegan admitted that although concern for Nightingale’s well-being, based on the report of suicide risk, was the primary reason for contacting Nightingale, a secondary purpose was to talk with Nightingale in light of his confessions to others. Keegan also admitted that he was the one to initiate the questioning on the topic of Nightingale’s confession to his mother and his friend. After confirming that Nightingale had spoken to his mother and friend, Keegan asked whether Nightingale had told them “that one [killing] was an accident and one was on purpose.” Nightingale responded in the affirmative. The State concedes that Nightingale was in custody shortly after the two officers entered his residence and therefore the initial statements are inadmissible.
[¶ 10] Keegan then read Nightingale his Miranda rights, after which Nightingale made further and more detailed incul-patory statements. At the outset of the post-Miranda questioning, Keegan referred back to Nightingale’s pre-Miranda statements, and got Nightingale to confirm that he had previously said he was “responsible for this” and that “one was an accident and one was on purpose.” It is evident in the transcript that Keegan was interrupted by the arrival of Nightingale’s mother as he was going over the Miranda warnings. He did not obtain an express waiver before getting Nightingale’s post-warning confession. He obtained the waiver at the end of the in-home interrogation.
[¶ 11] After Nightingale confessed, he told the police that he had taken the Millers’ safe and some other things to a camp belonging to his mother and stepfather, and he agreed to take the officers there. At the camp, the officers found a safe and a bag with some items in it, all belonging to the Millers.
[¶ 12] Nightingale was indicted in December 2009 on two counts of murder. He moved to suppress all statements he made during the polygraph interview, all statements made during the interrogation at his residence, and the physical evidence seized at the camp. The court granted the motion only as to the pre-warning statements made during the interrogation at Nightingale’s residence, and denied the motion as to (1) the statements Nightingale made during the interrogation at the Criminal Investigation Division, (2) the post-warning statements he made during the interrogation at his residence, and (3) the physical evidence seized after the post-warning statements.
[¶ 13] A six-day jury trial was held in May 2011. An audio file of the post-warning statement from the in-home interrogation was admitted in evidence at trial. The jury returned a verdict of guilty of the lesser-included offense of manslaughter on count one for the death of Michael Miller and guilty of murder on count two for the death of Valerie Miller. In September 2011, the court entered a judgment of conviction on both counts and sentenced Nightingale to concurrent terms of fifteen years on count one and forty years on count two, with no time suspended and no probation.
II. DISCUSSION
[¶ 14] Nightingale argues that he was in custody for purposes of Miranda v. Arizona,
A. Custody
[¶ 15] Nightingale argues that he was in custody at the Criminal Investigation Division on December 11 when he underwent the polygraph exam and the questioning leading up to it and following it. “We review the denial of a motion to suppress for clear error as to factual findings and de novo as to issues of law.” State v. Gould,
[¶ 16] In State v. Bridges,
[¶ 17] Here, Nightingale voluntarily participated in the interview after police asked whether he would be willing to undergo a polygraph examination. Nightingale drove himself to the Criminal Investigation Division. During the nine-hour interview, Nightingale was given the Miranda warnings twice. He was in a relatively small room with two unarmed detectives, dressed in street clothes. The officers told Nightingale at the beginning and end of the interview that he was free to terminate the interview at any time. He took breaks for food and to smoke. He appeared calm throughout the interview.
[¶ 18] Although there are factors that could support the conclusion that Nightingale was in custody, in particular the duration of the interrogation, see State v. Michaud,
B. The Shatzer Rule
[¶ 19] In Shatzer, the U.S. Supreme Court set a “minimum fourteen-day waiting period between the time the suspect is released from custody and when the police can reinitiate interrogation after the suspect initially invoked his or her right to counsel” pursuant to Miranda. State v. Knowlton,
C. Two-Step Interrogation
[¶ 20] Nightingale argues that his post-warning statements at his home should have been suppressed because the police employed a two-step interrogation procedure — that is, Keegan elicited a confession from Nightingale, administered Miranda, and then obtained a post-warning confession. The United States Supreme Court has addressed this “Miranda-m-the-middle” situation in two seminal cases: Oregon v. Elstad,
[¶ 21] Elstad was convicted of burglary. Elstad,
I sat down with Mr. Elstad and I asked him if he was aware of why Detective McAllister and myself were there to talk with him. He stated no, he had no idea why we were there. I then asked him if he knew a person by the name of Gross, and he said yes, he did, and also added that he heard that there was a robbery at the Gross house. And at that point I told Mr. Elstad that I felt he was involved in that, and he looked at me and stated, “Yes, I was there.”
Id. Elstad was transported to the sheriffs headquarters, given Miranda warnings for the first time about one hour later, waived his rights, and gave a full confession. Id.
[¶ 22] The Court held that “there is no warrant for presuming coercive effect
[I]n any such inquiry, the finder of fact must examine the surrounding circumstances and the entire course of police conduct with respect to the suspect in evaluating the voluntariness of his statements. The fact that a suspect chooses to speak after being informed of his rights is, of course, highly probative. We find that the dictates of Miranda and the goals of the Fifth Amendment proscription against use of compelled testimony are fully satisfied in the circumstances of this case by barring use of the unwarned statement in the ease in chief. No further purpose is served by imputing “taint” to subsequent statements obtained pursuant to a voluntary and knowing waiver. We hold today that a suspect who has once responded to unwarned yet uncoercive questioning is not thereby disabled from waiving his rights and confessing after he has been given the requisite Miranda warnings.
Id. The Court rejected the argument that to cure the Miranda violation the police must tell the suspect that his prior statement may not be used against him. Id. at 316,
[¶ 23] The facts at issue in Seibert differed significantly from those in Elstad in terms of police conduct. Seibert was convicted of murdering a mentally ill teenager in a fire deliberately set to destroy the dead body of Seibert’s disabled son in order to conceal the son’s bedsores that indicated that Seibert had neglected him before he died in his sleep. Seibert,
[¶ 24] The plurality in Seibert suggested that the following factors are relevant in determining whether confessions elicited after “midstream” Miranda warnings are admissible:
the completeness and detail of the questions and answers in the first round of interrogation, the overlapping content of the two statements, the timing and setting of the first and the second, the continuity of police personnel, and the degree to which the interrogator’s questions treated the second round as continuous with the first.
Id. at 615,
The unwarned interrogation was conducted in the station house, and the*1066 questioning was systematic, exhaustive, and managed with psychological skill. When the police were finished there was little, if anything, of incriminating potential left unsaid. The warned phase of questioning proceeded after a pause of only 15 to 20 minutes, in the same place as thе unwarned segment. When the same officer who had conducted the first phase recited the Miranda warnings, he said nothing to counter the probable misimpression that the advice that anything Seibert said could be used against her also applied to the details of the inculpatory statement previously elicited. In particular, the police did not advise that her prior statement could not be used.... The impression that the further questioning was a mere continuation of the earlier questions and responses was fostered by references back to the confession already given. It would have been reasonable to regard the two sessions as parts of a continuum, in which it would have been unnatural to refuse to repeat at the second stage what had been said before. These circumstances must be seen as challenging the comprehensibility and efficacy of the Miranda warnings to the point that a reasonable person in the suspect’s shoes would not have understood them to convey a message that she retained a choice about continuing to talk.
Id. at 616-17,
[¶ 25] Justice Kennedy’s concurrence in Seibert focuses on whether the two-step questioning process was a “deliberate” or “intentional” tactic by the police to undermine Miranda. Id. at 620-21,
[¶ 26] Under Justice Kennedy’s analysis, if the police deliberately used a two-step process, the question would then be whether curative measures made the Miranda warnings effective:
Curative measures should be designed to ensure that a reasonable person in the suspect’s situation would understand the import and effect of the Miranda warning and of the Miranda waiver. For example, a substantial break in time and circumstances between thе prewarn-ing statement and the Miranda warning may suffice in most circumstances, as it allows the accused to distinguish the two contexts and appreciate that the interrogation has taken a new turn. Alternatively, an additional warning that explains the likely inadmissibility of the prewarning custodial statement may be sufficient.
Id. at 622,
[¶ 27] The majority of the federal circuit courts have adopted the reasoning of Justice Kennedy’s concurrence, requiring an initial inquiry into the deliberateness of the two-step procedure, as controlling. See, e.g., United States v. Williams,
[¶ 28] Several circuits have not yet decided the issue of which Seibert test governs. See, e.g., United States v. Widi,
[¶ 29] We have previously described the holding in Seibert as standing for the proposition that “when the police delay giving a Miranda warning until after confession in a strategic effort to coerce the confession, the police misconduct may sufficiently taint all of the individual’s statements, notwithstanding later warnings, and suppression is required.” State v. Dodge,
[¶ 30] Here, the State conceded that Nightingale was in custody and subject to interrogation when the detectives first arrived at his mother’s home on the evening of the polygraph, and аs a result, the trial court suppressed all statements Nightingale made before Miranda warnings were given to him. The trial court found that the detectives had mixed motives when they arrived at the home. One purpose was to check on the status of Nightingale, in light of reports of possible suicide plans, and the other purpose was to take a statement from him after reports that he confessed to his mother and girlfriend. First, we note that Nightingale had been given his Miranda warnings twice, the most recent approximately five hours earlier. Second, in light of the suicide reports, the detectives were concerned about Nightingale’s sаfety. Events were moving rapidly when the detectives first arrived at the home in the late evening hours. After carefully reviewing the record, the trial court found that the detectives’ actions did not reflect a deliberate strategy to use “Mirawda-in-the-middle.” We find no error in its determinations.
D. Voluntariness
[¶ 31] Nightingale next argues that the use of deception by the police during the nine-hour interrogation rendered his in-home, post-warning confession involuntary. Nightingale does not contest the admission of any statements made during the nine-hour interrogation.
[¶ 32] The standard of review is clear error as to the factual findings and de novo as to the law. See State v. Lavoie,
[¶ 33] To be voluntary, a confession must be the “free choice of a rational mind,” “fundamentally fair,” and “not a product of coercive police conduct.” Id. (quotation marks omitted). The requirement that a statement be voluntary stems from the Fifth Amendment right against self-incrimination and the Fourteenth Amendment right to due process. Dickerson v. United States,
both extеrnal and internal factors, such as: the details of the interrogation; duration of the interrogation; location of the interrogation; whether the interrogation was custodial; the recitation of Miranda warnings; the number of officers involved; the persistence of the officers; police trickery; threats, promises or inducements made to the defendant; and the defendant’s age, physical and mental health, emotional stability, and conduct.
[¶ 34] In State v. Lavoie,
[¶ 35] In State v. Gould,
[¶ 36] The court herе found with respect to the first interrogation that the detectives’ false statements about the evidence did not have any appreciable effect on Nightingale, as he “largely deflected” their questioning and “proceeded through the interrogation undaunted.” In holding Nightingale’s later statements at his home voluntary, the court also considered that (1) there was no deliberate attempt to circumvent Miranda; (2) it is likely that Nightingale’s confessions to his mother and his friend made him recognize “the futility in making statements to police that were inherently inconsistent with the statements investigating authorities had obtained from third-party sourcеs”; (3) he was resigned that there was sufficient evidence to arrest him; (4) he was calm,
E. Fruit of the Poisonous Tree
[¶ 37] Finally, Nightingale argues that the physical evidence obtained as a result of his statements should have been suppressed as the fruits of constitutional violations. Because Nightingale’s post-warning statements were voluntary, the court did not err in admitting the physical fruits of those statements. See United States v. Patane,
F. Conclusion
[¶ 38] The court did not err in denying Nightingale’s motion to suppress as to his post-warning confession and the physical evidence obtained as a result.
The entry is:
Judgment affirmed.
Notes
. We note again that the results of polygraph tests are completely inadmissible because they have "non-existent value when it comes to determining credibility." State v. Harnish,
. In Seibert, the plurality characterized the “question-first” practice as popular in law enforcement; at least until the decision in Seibert, this interrogation method was actually departmental policy in many places, and a national police training organization trained law enforcement officers in the technique.
