OPINION
Before BRYNER, C.J., COATS, J., and ANDREWS, Superior Court Judge.*
PER CURIAM.
Jacob B. Kochutin, Jr., was convicted by a jury of one count of murder in the first degree and one count of sexual abuse of a minor in the first degree. Kochutin appeals, contending that the trial court erred in refusing to suppress statements that the police obtained from him as a result of custodial interrogation occurring in the absence of his counsel. Kochutin also pled no contest to a separate charge of sexual abuse of a minor in the first degree, reserving his right to appeal the trial court’s refusal to suppress the testimony of the alleged victim. On appeal, Kochutin claims that testimony, which was obtained as the result of improper custodial interrogation, should have been suppressed. We reverse Kochutin’s convictions for murder and the related charge of sexual abuse; we remand for further proceedings on the charge of sexual abuse to which Kochutin pled no contest.
[300]*300FACTS
The parties have stipulated to the relevant facts. Seven-year-old T.T. disappeared from his home on St. Paul Island sometime between June 24 and June 26, 1984. An extensive search produced no trace of T.T. Approximately thirteen months later, on July 25, 1985, T.T.’s body was discovered in a trunk in the St. Paul home of Kochutin’s uncle. An autopsy revealed that T.T. had been dead for approximately a year and that he apparently died from repeated stabbings. The condition of T.T.’s clothing indicated that he had been sexually abused.
Kochutin, who resided on St. Paul Island when T.T. disappeared, was a suspect in the child’s death. When T.T.’s body was found, Kochutin was imprisoned at the Palmer Correctional Center, serving a sentence for unrelated offenses. The day after T.T.’s body was discovered, prison officials noticed that Kochutin missed two meals, appeared to be agitated, and began using the inmates’ pay phone more than usual. Suspecting that news of T.T.’s discovery may have triggered Kochutin’s behavior and fearing a possible escape attempt, officials moved Kochutin from the minimum custody portion of the institution into a more secure administrative segregation unit. Prison officials also contacted the Alaska State Troopers in Palmer and advised them of Kochutin’s behavior and his transfer to administrative segregation. Eleven days later, on August 6, 1985, Ko-chutin was transferred from the Palmer Correctional Center to the even more secure administrative segregation unit at the Cook Inlet Pretrial Facility in Anchorage. The transfer was again based on the fear that, as a murder suspect, Kochutin might attempt to escape.
In the meantime, Alaska State Trooper Rollie Port, who was working on T.T.’s murder investigation, became interested in interviewing Kochutin. Kochutin was one of several people whom Port regarded as a suspect. Port consulted with the Anchorage District Attorney’s Office about the possibility of interrogating Kochutin, but was instructed on August 9, 1985, to refrain from any contact with Kochutin until the state had researched the legality of a jailhouse interview. Port was told that he would hear back from the district attorney’s office within about two weeks.
On August 12 or 13, 1985, however, while Port awaited word from the district attorney’s office, Kochutin telephoned Assistant Public Defender William F. Morse, who had been representing him on several cases since May 1, 1984, including the charges for which he was imprisoned. Ko-chutin asked Morse why he was transferred to the Cook Inlet Pretrial Facility.
Morse made several inquiries in response to Kochutin’s request and learned that Ko-chutin had been transferred because he was a suspect in the recently discovered St. Paul homicide. On August 13, 1985, Morse called Port and asked him to refrain from speaking with Kochutin unless Morse was present. Port told Morse that he planned to be in Anchorage the following day and wanted to arrange an interview with Ko-chutin then. Morse said that he would visit Kochutin in jail and call Port back.
The next day, August 14, 1985, Morse visited Kochutin and spoke with him about Port’s request for an interview. After the visit, Morse notified Port and the Anchorage District Attorney’s Office by telephone that Kochutin was not interested in speaking with the authorities about the homicide investigation. On August 15, 1985, Morse wrote a letter to Port and the district attorney’s office, confirming that Kochutin did not want to speak with the authorities. In the letter, Morse indicated that he would let investigators know if Kochutin changed his mind.
Approximately a week later, the state arrested another St. Paul resident, Xeno-font Emanoff, on charges of sexually abusing T.T. shortly before the child’s disappearance in June of 1984. The police had focused on Emanoff as another possible suspect in T.T.’s homicide. When Emanoff was arraigned in St. Paul after being arrested on Augu'st 23, the St. Paul magistrate appointed Morse to represent Ema-noff, since Morse had been handling the St. [301]*301Paul calendar for the public defender agency-
When Emanoff was indicted in Anchorage several days later for the sexual abuse of T.T., the district attorney’s office objected to Emanoff s representation by the public defender agency noting that Morse’s representation of Kochutin in connection with the pending homicide investigation posed a potential conflict. On September 5, 1985, the superior court, after holding a hearing, granted the state’s motion to disqualify the public defender agency and ordered the appointment of conflict counsel for Emanoff.
For the balance of 1985, the state made no further effort to contact Kochutin. At some point that fall, Kochutin was transferred from his placement in administrative segregation at the Cook Inlet Pretrial Facility, and by December of 1985 he was back in normal institutional placement as a sentenced prisoner at the Hiland Mountain Correctional Facility.
The investigation of T.T.’s homicide remained unresolved. By the summer of 1986, the Alaska State Troopers were anxious to wrap the case up. The list of suspects had narrowed to Kochutin, Ema-noff, and two other men; all four were incarcerated in the Anchorage area. Ema-noff’s trial for sexually abusing T.T. was scheduled for September of 1986. The troopers and the district attorney’s office both thought it desirable to charge Ema-noff or eliminate him as a homicide suspect before his sexual abuse trial.
On August 13, 1986, exactly a year after first being told that Morse represented Ko-chutin in connection with T.T.’s homicide, Trooper Robert Stevenson and Port met with the district attorney and discussed the status of the investigation. By that time, Kochutin was incarcerated at the Sixth Avenue jail in Anchorage, still serving a sentence for unrelated offenses. The district attorney and Port both believed that Ko-chutin might be willing to speak with them without Morse present, but both felt that no interview would be possible if they notified Morse first. After checking Kochu-tin’s status and learning that he had no pending or unresolved criminal charges against him, the district attorney advised the troopers to contact Kochutin in jail and attempt to interview him without first notifying Morse.
Stevenson visited Kochutin at the Sixth Avenue jail later that same day. As planned, Morse was given no notice of the interview. Stevenson advised Kochutin of his Miranda1 rights and reminded him that he had an attorney, Morse, and could request Morse’s assistance if he so wished. Kochutin, however, agreed to speak with Stevenson. In the course of the August 13 interview, Kochutin agreed to submit to a polygraph test the next day.
The next day, Stevenson transported Ko-chutin to trooper headquarters in Anchorage and placed him in the custody of Trooper Paul Burke, a polygraph examiner. Burke proceeded to interview Kochutin and perform a polygraph test. Although Ko-chutin was given information concerning the polygraph and signed a form regarding liability of the polygraph examiner, he was not readvised of his Miranda rights by Burke. During the polygraph test, Kochu-tin denied involvement in T.T.’s homicide. Upon completion of the test, Burke concluded that Kochutin had been deceptive; he relayed his conclusions to Port.
By the time Port learned the results of the polygraph test, Kochutin had been returned to the Sixth Avenue jail. Port had Kochutin brought back to trooper headquarters for an additional interview. When Kochutin arrived, Port confronted him with the polygraph results. Port did not readvise Kochutin of his rights, mistakenly believing that Burke had done so prior to the polygraph test. In the course of the interview with Port, Kochutin admitted “accidently” stabbing T.T. and placing his body in a trunk.
A day later, August 15, Port and Stevenson jointly interviewed Kochutin. They gave Kochutin his Miranda warnings at the outset of the interview, and Kochutin [302]*302again consented to an interview. Kochutin made further incriminating statements.
On August 18, Port again interviewed Kochutin, once more advising him of his rights before beginning the interrogation. In this interview, Kochutin acknowledged sexually molesting T.T. before killing him. Kochutin said he got angry at T.T. because the boy resisted; Kochutin stabbed T.T. when he tried to run away. During this interview, Kochutin also admitted sexually abusing another boy, M.T.
Port conducted a final interview with Ko-chutin on August 20, 1986. Prior to the interview, Port and the district attorney had become aware that Kochutin was not readvised of his Miranda rights before the August 14 polygraph test and follow-up interview. They prepared an augmented Miranda warning, hoping to remove any taint resulting from the failure to readvise Kochutin. In addition to the usual Miranda warning, Port advised Kochutin of the possibility that his prior incriminating statements might not be admissible in evidence against him. Port emphasized that if Kochutin agreed to a further interview, he should do so because he wanted to talk to the police and not simply because he had already made incriminating statements. Kochutin agreed to the additional interview and again described the sexual abuse and murder of T.T. as he had on August 18.
Within a week, the state charged Kochu-tin with the murder and sexual abuse of T.T., as well as with sexual abuse of M.T. Only after the formal charges were filed was the public defender agency informed that Kochutin had been contacted in jail and interviewed by the troopers.
The sexual abuse charge relating to M.T. was severed from the two charges dealing with T.T. As to the charges involving T.T., Kochutin moved to dismiss the indictment and to suppress the statements that he had given to the troopers. He argued that the police-initiated interviews of August 13, 14, 15, 18, and 20 were impermissible because they occurred in the absence of Morse, his counsel, and violated Kochutin’s decision not to speak with the authorities about the T.T. homicide, which he communicated through Morse to both the district attorney’s office and the troopers a year previously. Kochutin further argued that, even assuming the police interviews were not per se impermissible, the failure to give Miranda warnings before the polygraph test and the post-polygraph interview on August 14 mandated suppression of all the statements that he made that day and in subsequent interviews.
Superior Court Judge Victor D. Carlson denied the dismissal and suppression motions. Judge Carlson found that Morse’s August, 1985, attempt to invoke Kochutin’s right to remain silent and to have counsel present during interrogation was ineffective and premature because the attempted invocation was not personally made by Ko-chutin, and occurred before any actual custodial interrogation began. Judge Carlson further determined that it was unnecessary to readvise Kochutin of his Miranda rights on August 14, 1986, since he had already been advised of his rights on August 13, and had consented to an interview. Kochu-tin was subsequently tried before a jury and convicted of the murder and sexual abuse charges involving T.T.
Kochutin separately moved to suppress the testimony of the victim, M.T., in the sexual abuse case that had been severed from the charges relating to T.T. Advancing the same arguments he used in the case involving T.T., Kochutin alleged that his August 20 confession as to M.T. was unlawfully obtained. Kochutin argued that the police had obtained M.T.’s testimony as a direct result of that confession. He thus maintained that M.T.’s testimony was suppressible under the fruit-of-the-poisonous-tree doctrine. Judge Carlson, adopting his ruling in the T.T. case, denied Kochu-tin’s motion to suppress. In so doing, however, Judge Carlson expressed the view that the fruit-of-the-poisonous-tree doctrine would have been applicable to M.T.’s testimony if Kochutin’s August 20 confession had been unlawfully obtained. Upon receiving Judge Carlson’s ruling, the parties stipulated that the suppression issue was dispositive, and Kochutin entered a plea of no contest, reserving his right to appeal.
[303]*303DISCUSSION
On appeal, Kochutin argues that Judge Carlson erred in denying his suppression motion. Kochutin’s principal argument is that the August 13 through 20, 1986, interviews were impermissible under the rule of Miranda v. Arizona, 384 U.S. 436, 86 S.Ct. 1602, 16 L.Ed.2d 694 (1966), and Edwards v. Arizona, 451 U.S. 477,101 S.Ct. 1880, 68 L.Ed.2d 378 (1981).
In Miranda, the United States Supreme Court found that police interrogation of persons in custody chilled the exercise of the right against self-incrimination, as guaranteed by the fifth and fourteenth amendments to the United States Constitution. To protect this right, the Court required the police to give certain warnings before questioning a person in custody. Among the rights included in the mandatory warnings is the right to consult an attorney and to have the attorney present during interrogation. Under Miranda, when a suspect requests an attorney during custodial interrogation, all questioning must cease until an opportunity to consult with counsel has been provided.
In Edwards, 451 U.S. at 484-85, 101 S.Ct. at 1884-85, the Supreme Court expanded the Miranda rule. Edwards adopted a prophylactic rule holding that once a suspect invokes the right under Miranda to consult with counsel, and thereby terminates an interrogation, the police are barred from any subsequent effort to initiate further interrogation until the suspect has been given the opportunity to consult with counsel. Under the per se rule of Edwards, police-initiated reinterro-gation is prohibited even when the suspect, upon being recontacted, expressly waives his Miranda rights.
Kochutin argues that the Edwards rule applies to his case. He points out that he was in custody at the Palmer Correctional Center in July of 1985, when T.T.’s body was discovered. Because he was a suspect in the murder, he was subjected to additional restraints, first in administrative segregation at Palmer, and later by being transferred to administrative segregation at the Cook Inlet Pretrial Facility. At that point, Kochutin consulted with his attorney, who made it clear to the district attorney’s office and the troopers that he represented Kochutin in connection with the pending investigation and that Kochutin wished to invoke his Miranda rights to remain silent and to have counsel present.
Kochutin emphasizes that the state was clearly aware of and accepted the fact that Morse was representing him, since it moved to disqualify Morse and the public defender agency from representing Ema-noff, another potential suspect in the murder of T.T., on grounds of conflict. Kochu-tin further points out that, from the time Morse invoked his right to remain silent in August of 1985, until the police initiated the first contact with him in jail a year later, on August 13, 1986, he remained in continuous custody. Kochutin asserts that, as long as he remained in continuous custody after invoking his Miranda rights, Edwards precluded the police from initiating any further contact without Morse, his attorney, being present.
The state acknowledges, in response, that Judge Carlson was mistaken in rejecting Kochutin’s Edwards argument on the ground that Kochutin’s attempt to assert his Miranda rights had been premature and was not personally made. The state concedes that Kochutin could properly assert his Miranda rights through counsel rather than personally and that the assertion could properly be made in anticipation of custodial interrogation instead of at the outset of an actual interview. The state’s concession on this score certainly appears to be well founded. See, e.g., Michigan v. Jackson, 475 U.S. 625, 106 S.Ct. 1404, 89 L.Ed.2d 631 (1986); United States v. Wolf, 879 F.2d 1320 (6th Cir.1989); Cervi v. Kemp, 855 F.2d 702, 706-07 (11th Cir. 1988).
The state nevertheless insists that Edwards is inapplicable to Kochutin’s case. According to the state, Edwards requires only that a prisoner be given the opportunity to consult with counsel; once a person is afforded the opportunity to consult with an attorney, the Edwards prohibition ceases [304]*304to apply, and the police may again initiate contact.
Whatever force this argument might once have had, it is now clearly untenable. After the state filed its brief in the present ease, the United States Supreme Court issued its decision in Minnick v. Mississippi, — U.S.-, 111 S.Ct. 486, 112 L.Ed.2d 489 (1990), expressly rejecting the narrow reading of Edwards that the state here proposes. In Minnick, the Court held that the right to counsel under Miranda and Edwards includes not only an opportunity to consult with an attorney, but also the opportunity to have the attorney present during any custodial interrogation. Thus, according to the Court in Min-nick, once a suspect invokes the right under Miranda to consult with counsel, the police are flatly precluded from initiating any further contact unless the person’s attorney is present.
The state further argues, however, that even if Edwards is not narrowly read, it remains inapplicable to Kochutin’s case. According to the state, Edwards applies only to suspects who remain in continuous custody after making an initial request to consult with counsel. See, e.g., United States ex rel. Espinoza v. Fairman, 813 F.2d 117, 122, 124-27 (7th Cir.1987). The state points out that in Kochutin’s case, the challenged interviews occurred a full year after Morse had asserted Kochutin’s right to remain silent; although Kochutin was technically still in custody, he was apparently confined as a sentenced prisoner serving a term for unrelated offenses. Kochu-tin was not in detention for T.T.’s homicide, and the district attorney took the precaution of ascertaining that he had no other cases pending. The state contends that Kochutin’s status as a sentenced prisoner and the amount of time that elapsed after he invoked his right to remain silent removed his case from the Edwards rule.
Although the dissent in this case finds the state’s argument persuasive, we do not. The United States Supreme Court made it clear in Minnick that Edwards adopted a “bright-line” rule that can be easily understood and predictably applied. Ill S.Ct. at 90-92. Exceptions to the Edwards rule should not be carved out lightly. The exception to Edwards that the state proposes in this case is simply an argument that Edwards ought not to apply to Kochutin’s situation, even though Kochutin undeniably invoked his Miranda rights and was thereafter subjected to police-initiated custodial reinterrogation without counsel present. This type of fact-specific analysis is precisely the type of uncertain case-by-case adjudication that the bright-line rule in Edwards is meant to avoid.
Moreover, the state’s proposed Edwards exception presupposes that the Edwards rule applies only to suspects who remain in continuous custody after invoking their Miranda rights. The “continuous custody” requirement that the state relies on appears to have first been articulated by the court in Fairman, 813 F.2d at 124-27. Although, as the dissent in this case notes, this requirement seems to have been generally accepted by federal appellate courts, it has never been definitively ruled on by the United States Supreme Court, and was not expressly adopted in Edwards.
In any event, Kochutin actually did remain in continuous custody between August of 1985, when he first invoked his Miranda rights, and August of 1986, when Stevenson contacted him at the Sixth Avenue jail without notifying Morse. Not only did Kochutin remain continuously in custody, but the subject of the police-initiated questioning in Morse’s absence was precisely that to which Kochutin originally invoked his Miranda rights.
We find nothing in Edwards or in subsequent decisions of the Supreme Court to indicate that Edwards should be relaxed by the mere passage of time. Nor are we persuaded that Kochutin’s status as a sentenced prisoner removes his case from coverage of the Edwards rule.2 The fact that [305]*305Kochutin was not being detained in connection with T.T.’s homicide seems immaterial, since the United States Supreme Court has made it clear that Edwards applies even when police seek to question a suspect about charges other than those for which the suspect was arrested and as to which the suspect first invoked the right to remain silent. See Arizona v. Roberson, 486 U.S. 675, 108 S.Ct. 2093, 100 L.Ed.2d 704 (1988).
As evidenced by the fact that the troopers deemed it necessary to advise Ko-chutin of his Miranda rights, the interviews that occurred at the Sixth Avenue jail and at trooper headquarters in August of 1986 plainly amounted to custodial interrogation. Under the circumstances, it appears that the Edwards rule was applicable. Under Edwards, the police-initiated interviews were impermissible because they occurred without notice to Morse and without Morse’s presence. As a result, Kochutin’s apparent willingness to waive his Miranda rights is inconsequential.
Even if Edwards were not strictly applicable in this case, we would be inclined to find that, under the totality of the circumstances, Kochutin’s Miranda waivers were not voluntary. The state bears the burden of proving the validity of a Miranda waiver and the voluntariness of a confession by a preponderance of the evidence. State v. Ridgely, 732 P.2d 550, 554-55 (Alaska 1987); Giacomazzi v. State, 633 P.2d 218, 222 n. 4 (Alaska 1981). While this court is bound by the trial court’s findings of historical fact, we decide the ultimate issue of voluntariness independently, without deference to the trial court’s conclusion. The decision is one that must be based on the totality of circumstances in each case. Ridgely, 732 P.2d at 555-56.
In the present case, we accept the trial court’s findings of historical fact, which were largely the product of a stipulation between the parties. It is undisputed that Kochutin affirmatively sought out Morse’s assistance after being placed in administrative segregation as a suspect in T.T.’s homicide. Having consulted with Morse, Kochutin decided that he did not desire to be questioned by the authorities; he communicated his wishes through Morse and clearly indicated that Morse would notify the authorities if he changed his mind. Thereafter, the troopers, in concert with the Anchorage District Attorney, specifically decided to bypass Morse and obtain an interview with Kochutin alone, in jail. They did so knowing full-well that on prior occasions when Kochutin had been interviewed by the police in the absence of counsel he had waived his Miranda rights and confessed to unrelated crimes. It is clear from the record that the district attorney and the troopers believed it likely that they would be able to obtain a statement from Kochutin if they could interview him without his attorney present, and unlikely if they could not.
In deciding Miranda, the United States Supreme Court emphasized that giving the required Miranda warnings would not in itself assure the voluntariness of any subsequent interrogation. The Court cautioned:
If the interrogation continues without the presence of an attorney and a state[306]*306ment is taken, a heavy burden rests on the government to demonstrate that the defendant knowingly and intelligently waived his privilege against self-incrimination and his right to retained or appointed counsel. This Court has always set high standards for proof for the waiver of constitutional rights, and we reassert those standards as applied to in-custody interrogation. Since the state is responsible for establishing the isolated circumstances under which the interrogation takes place and has the only means of making available corroborated evidence of warnings given during incommunicado interrogation, the burden is rightly on its shoulders.
An express statement that the individual is willing to make a statement and does not want an attorney followed closely by a statement could constitute a waiver. But a valid waiver will not be presumed simply from the silence of the accused after warnings are given or simply from the fact that the confession was in fact eventually obtained.
384 U.S. at 475, 86 S.Ct. at 1628 (citations omitted). In the present ease, considering the totality of the circumstances, we find that the state has failed to meet its heavy burden of showing a voluntary Miranda waiver.
We do not hold that a person who requests counsel during a custodial interrogation may never afterward voluntarily waive his Miranda rights in the absence of counsel. We do hold, however, that on the particular facts of this case, Kochutin’s Miranda rights were violated. Here, as we have noted, Kochutin clearly communicated to the authorities his personal belief that he could not adequately protect his rights unless counsel was present with him during the interrogation pertaining to the T.T. homicide. The state affirmatively acknowledged Morse’s role in representing Kochutin. In the face of Kochutin’s clear communication, and while Kochutin remained incarcerated, the authorities nevertheless sought to interview him in Morse’s absence, in jail, on the precise issue as to which Kochutin had initially invoked his Miranda rights. When they reinitiated contact with Kochutin, the troopers had no information indicating that Kochutin was desirous of contacting them or that he had any reason to change his mind with respect to his previously expressed decision to decline a police interview.
We are particularly troubled that Kochu-tin’s interrogation took place at the direction of the Anchorage District Attorney, despite his awareness that Kochutin had been represented by Morse in connection with the investigation of T.T.’s death. Judge Carlson found that, under the circumstances, the prosecutor violated the Alaska Code of Professional Responsibility, Disciplinary Rule 7-104(A)(l), which provides, in relevant part:
(A) During the course of his representation of a client a lawyer shall not:
(1) Communicate or cause another to communicate on the subject of the representation with a party he knows to be represented by a lawyer in that matter unless he has the prior consent of the lawyer representing such other party or is authorized by law to do so.
Judge Carlson declined to suppress Kochu-tin’s confession on this basis alone, finding that suppression was not an appropriate remedy for violation of the disciplinary rule.
Although we are inclined to agree that a violation of this disciplinary rule will not necessarily trigger the sanction of suppression, we consider the violation in this case significant because of its relevance on the issue of voluntariness. In our view, the willingness of the district attorney to violate the disciplinary rule by knowingly bypassing Kochutin’s counsel underscores the authorities’ awareness that Kochutin would have been unlikely to waive his Miranda rights if given the opportunity to speak with Morse. This in turn provides a strong indication that the troopers and the district attorney believed that, to obtain a statement from Kochutin, they would have to interrogate him in a setting in which it was unlikely that he would be able to make an informed and intelligent decision as to his own best interests. If this is true, then it is difficult to see how Kochutin can real[307]*307istically be said to have knowingly, intelligently, and voluntarily waived his fifth amendment rights.
Under these peculiar circumstances, we decline to find that Kochutin’s unexplained willingness to waive the presence of counsel was voluntary. Accordingly, we conclude that the superior court erred in denying the motion to suppress Kochutin’s statements. To reiterate, our holding is based on two alternative grounds. First, we conclude that the police-initiated interrogations of Kochutin were impermissible under the rule of Edwards. Second, even if Edwards is inapplicable, we find, under the totality of the circumstances, that Ko-chutin did not knowingly, intelligently, and voluntarily waive his Miranda rights.
Although our decision necessitates reversal of Kochutin’s conviction for the murder and sexual abuse of T.T., we must separately consider his conviction for the sexual abuse of M.T. The specific issue presented is whether M.T.’s proposed testimony against Kochutin is subject to suppression as a fruit of Kochutin’s improper interrogation.
Kochutin admitted sexually abusing M.T. during his interview with Port on August 18, 1986. Prior to that time, the troopers had apparently interviewed M.T. in connection with T.T.’s disappearance and had asked if M.T. was ever sexually abused by Kochutin. M.T. had evidently denied any sexual abuse. After Kochutin told Port that he had sexually abused M.T., Port traveled to St. Paul Island for an additional interview with M.T. M.T. initially denied sexual contact with Kochutin, but after Port told him that Kochutin had confessed, M.T. confirmed that sexual contact had occurred.
In moving for suppression below, Kochu-tin claimed that M.T.’s testimony resulted directly from his improperly obtained confessions and was therefore suppressible under the fruit-of-the-poisonous-tree doctrine. Judge Carlson denied Kochutin’s motion based on the conclusion that the authorities did not act improperly in obtaining Kochu-tin’s confession. The judge went on to find, hypothetically, that M.T.’s testimony would have been subject to the fruit-of-the-poisonous-tree doctrine had Kochutin’s confession been illegally obtained.
On appeal, Kochutin again claims that M.T.’s testimony must be suppressed as the fruit of the improper interrogations. However, Kochutin advances this claim in a single, eonelusory paragraph that cites no supporting authority whatsoever. In response, the state has presented a forceful argument, supported by substantial authority, casting serious doubt on the question of whether M.T.'s testimony should be subject to suppression.3 Kochutin has not addressed the state’s arguments in his reply brief.
Given Kochutin’s failure to cite or discuss any authority for his claim that M.T.’s testimony should be suppressed, and his failure to respond to the contrary argument and authorities relied on by the state, we find that this issue has not been adequately briefed. Moreover, it appears that, because this issue was presented to the [308]*308trial court without an evidentiary hearing, on stipulated facts, the factual record currently before this court does not permit a meaningful decision as to whether M.T.’s testimony should be suppressed.
From our review of case law in the area, it appears that proper resolution of this issue may hinge on particular circumstances, such as: the role played by Kochu-tin’s statements in inducing M.T.’s cooperation; the length of time between Kochu-tin’s statements and the discovery of M.T.’s testimony; the extent to which M.T. was known to the police as a potential victim of sexual abuse prior to Kochutin’s statements; the degree of free will exercised by M.T. in agreeing to testify; and, the time, place, and manner of any questioning of M.T. by the troopers. See, e.g., People v. Briggs, 709 P.2d 911, 918 (Colo.1985); State v. Childress, 35 Wash.App. 314, 666 P.2d 941, 943 (1983).
The conclusory attention given by Ko-chutin to this issue in his briefs may be the result of the peculiar procedural manner in which this issue was presented to the superior court. Kochutin’s motion to suppress M.T.’s testimony seems to have been made in anticipation of a plea of no contest under Oveson v. Anchorage, 574 P.2d 801 (Alaska 1978), and Cooksey v. State, 524 P.2d 1251 (Alaska 1974). Judge Carlson had evidently already ruled against Kochutin on the primary question of whether the police had violated Kochutin’s Miranda rights by interrogating him in the absence of counsel. Judge Carlson appears to have been asked to consider the fruit-of-the-poisonous-tree issue only as a secondary, hypothetical matter.
The state, in its brief, suggests that one appropriate remedy on this issue might be to remand to the superior court for additional fact finding. Under the circumstances, we agree that the issue must be remanded for reconsideration by the superior court after a full evidentiary hearing concerning the circumstances surrounding M.T.’s complaint and after more complete briefing on the issue by the parties.
