    STATE OF CONNECTICUT v. LAZALE ASHBY
    (SC 18190)
    Robinson, C. J., and Palmer, McDonald, D’Auria,
    Mullins, Kahn and Ecker, Js.*
    Syllabus
    Convicted of the crimes of capital felony, murder, felony murder, sexual
    assault in the first degree, kidnapping in the first degree, and burglary
    in the first degree in connection with the stabbing and strangulation of
    the victim in her apartment, the defendant appealed to this court. The
    police arrested the defendant when his DNA profile was matched to
    DNA taken from the victim’s vaginal swab, and, after the defendant was
    confronted with that evidence, he gave the police a written confession.
    Evidence presented at trial established that a second, unidentified male
    also contributed to the DNA on the victim’s vaginal swab, and unidenti-
    fied male DNA also was discovered on the doorframe of the victim’s
    bedroom and in saliva found on the victim’s shoulder. Prior to the
    defendant’s trial, P, a jailhouse informant who was incarcerated with
    the defendant, wrote a letter to W, a detective with the Hartford Police
    Department, indicating that he had information about the defendant
    that would be useful to W and referencing an unrelated criminal case
    pending against the defendant. W subsequently met with P at the prison,
    where they discussed the defendant’s involvement in the victim’s death,
    whether P might receive a benefit for providing additional information,
    and whether P would be willing to wear a wire. When W did not contact
    P again after the meeting, P informed the defendant of the meeting, and
    the defendant devised a ruse intended to undermine W’s credibility in
    anticipation of W’s testimony at trial. A few days before the state was
    to rest its case, P contacted W and informed W of the defendant’s ruse,
    and the state notified the defense that it intended to call P as a witness.
    The defendant filed a motion to suppress P’s testimony, which the trial
    court denied, concluding that P had not been acting as an agent of the
    state when he elicited information from the defendant. Thereafter, the
    defendant requested an instruction on third-party culpability in connec-
    tion with the presence of the unidentified male DNA found in and on
    the victim’s body and at the crime scene, but the trial court declined
    to give that instruction. On appeal from the judgment of conviction, the
    defendant claimed that the state violated his sixth amendment right
    to counsel by using P as an agent to deliberately elicit incriminating
    statements from the defendant, there was insufficient evidence to sup-
    port his conviction of burglary in the first degree, and the trial court
    improperly declined to provide a third-party culpability instruction to
    the jury in light of the unidentified male DNA discovered in and on the
    victim’s body and at the crime scene. Held:
    1. The trial court improperly denied the defendant’s motion to suppress
    P’s testimony in violation of the defendant’s sixth amendment right to
    counsel because P was acting as an agent of the state when he deliber-
    ately elicited incriminating statements from the defendant, and, accord-
    ingly, the judgment of conviction was reversed and the case was
    remanded for a new trial: although there was no express or formal
    agreement between P and W, in light of the totality of the circumstances,
    P’s efforts to elicit incriminating statements from the defendant were
    fairly attributable to the state, as the meeting between P and W empha-
    sized what useful, incriminating information P might obtain as a result
    of his future assistance and specifically focused on P’s efforts to obtain
    information from the defendant, possibly through wearing a wire or by
    other means, about his specific involvement in the victim’s death rather
    than his involvement in unrelated criminal cases; moreover, P and W
    discussed P’s interest in receiving a benefit in exchange for his coopera-
    tion, W indicated that the state’s attorney would have to approve any
    such deal, and, after P testified at the defendant’s trial, the state in fact
    provided P with his desired benefit by agreeing not to object to P’s
    attempt to secure a sentence modification, which P and W had discussed
    during their meeting; furthermore, the psychological pressures inherent
    in confinement, along with P’s lengthy consecutive sentences, provided
    P with a strong incentive to cooperate with the state, W never directed
    P to cease eliciting information from the defendant or to avoid conversa-
    tions with the defendant until the state’s attorney had approved of P’s
    cooperation with W, and the state either knew or should have known
    that W’s meeting with P was likely to result in further elicitation of
    information from the defendant.
    (One justice concurring in part and dissenting in part)
    2.This court declined the defendant’s invitation to overrule its holding in
    State v. Allen (
    216 Conn. 367
    ), and, accordingly, the defendant could
    not prevail on his claim that the evidence was insufficient to establish
    that he remained unlawfully in the victim’s apartment for purposes of
    his conviction of burglary in the first degree; contrary to the defendant’s
    assertion that Allen improperly conflates the burglary elements of intent
    and unlawful remaining, that case stands for the narrow proposition
    that the state may prove an unlawful remaining on the premises, for
    purposes of first degree burglary, by proffering evidence that a defendant
    has engaged in conduct on the premises that was likely to terrorize the
    occupants, and the defendant advanced no argument that his conduct
    in the victim’s apartment was unlikely to terrorize the victim; moreover,
    this court’s narrow reading of Allen was bolstered insofar as the Appel-
    late Court has consistently restricted its application of Allen to cases
    in which the state has presented evidence that the defendant engaged
    in conduct likely to terrorize occupants, and the fact that the legislative
    history of recent amendments to the burglary statutes strongly indicated
    that the legislature has acquiesced in this court’s decision in Allen coun-
    seled strongly against overruling Allen in favor of a more restrictive
    statutory interpretation of the relevant statutory ((Rev. to 2001) §§ 53a-
    100 (b) and 53a-101 (a) (2)) language; furthermore, variations among
    jurisdictions with respect to the law of burglary and license to remain
    did not justify departing from the weighty considerations attendant to
    stare decisis.
    3. The trial court abused its discretion by declining to provide a third-party
    culpability instruction to the jury, as the defendant established a direct
    connection between a third person and the charged offenses; the evi-
    dence reasonably supported an instruction on third-party culpability,
    as unidentified male DNA was recovered directly from the victim’s body
    and from the blood covered doorframe of her bedroom, rather than
    from the periphery of the crime scene, and the DNA on the victim’s
    shoulder would have existed only for a limited duration and was not
    otherwise explained by the record.

    Procedural History
    Substitute information charging the defendant with
    three counts of the crime of kidnapping in the first
    degree, two counts of the crime of capital felony, and
    one count each of the crimes of murder, felony murder,
    sexual assault in the first degree, and burglary in the
    first degree, brought to the Superior Court in the judicial
    district of Hartford and tried to the jury before
    Espinosa, J.; verdict of guilty; thereafter, during the
    penalty phase of the proceedings, the jury found that
    the existence of aggravating factors outweighed the
    mitigating factors, and the court rendered judgment of
    guilty in accordance with the verdict and imposed the
    death penalty on each count of capital felony and terms
    of imprisonment on the remaining counts, from which
    the defendant appealed to this court; subsequently, the
    trial court, Dewey, J., granted in part the defendant’s
    postjudgment motion for an evidentiary hearing but
    denied the relief requested; thereafter, the trial court,
    Baldini, J., resentenced the defendant on each count
    of felony murder to a term of life imprisonment without
    the possibility of release. Reversed; new trial.

    Opinion
    ROBINSON, C. J. The principal issue in this appeal
    is whether the state violated its affirmative obligation
    under Massiah v. United States, 
    377 U.S. 201
    , 206, 
    84 S. Ct. 1199
    , 
    12 L. Ed. 2d 246
     (1964), and its progeny to
    respect and preserve an invocation of the right to coun-
    sel under the sixth amendment to the United States
    constitution by using a jailhouse informant, Kenneth
    Pladsen, Jr., to deliberately elicit certain incriminating
    statements from the defendant, Lazale Ashby. The
    defendant, who was convicted of several crimes in con-
    nection with a murder in the city of Hartford on the
    night of December 1, 2002, appeals1 from the underlying
    judgment, raising numerous claims of error. For the
    reasons that follow, we conclude that the defendant’s
    constitutional right to counsel was violated and, accord-
    ingly, that he is entitled to a new trial on all counts.
    With respect to the defendant’s other claims, we con-
    clude that (1) he is not entitled to a judgment of acquittal
    on the charge of burglary in the first degree in violation
    of General Statutes (Rev. to 2001) § 53a-101 (a) (2) on
    the ground of insufficient evidence, and (2) the trial
    court improperly declined to provide a third-party cul-
    pability instruction to the jury in light of certain uniden-
    tified male DNA discovered at the crime scene.2
    The record reveals the following relevant facts and
    procedural history. On December 1, 2002, the victim3
    was living with her two year old daughter on the second
    floor of a three story apartment building located on
    Zion Street in Hartford. At approximately 7 p.m. that
    evening, Yvette Davila, who lived in an apartment on
    the third floor, invited the victim’s daughter upstairs to
    watch Rudolph the Red-Nosed Reindeer on television.
    The victim went upstairs about one-half hour later, left
    her daughter with Davila, and never returned. Although
    Davila made several attempts to contact the victim over
    the hours that followed, those efforts proved unsuccess-
    ful. Davila’s husband, Daniel Roman, went downstairs
    the following morning, noticed that a door to the vic-
    tim’s apartment was ajar, and stepped into the victim’s
    kitchen. Once inside, Roman saw the victim’s naked
    body lying on the floor of an adjacent bedroom. Roman
    then went back upstairs to his apartment, where he
    and Davila called the police at 7:17 a.m.
    The evidence offered at trial indicates that the victim
    died as the result of strangulation. Specifically, an exam-
    ination of the body revealed petechial hemorrhages and
    neck abrasions consistent with the use of an irregular
    ligature. The victim had also sustained several nonfatal
    injuries, including numerous stab wounds to her back.
    Forensic evidence did not establish an exact time of
    death, but the presence of rigor mortis indicated that
    the victim had been dead for hours by the time the
    paramedics arrived that morning. A significant amount
    of blood was found in both the kitchen and the bed-
    room.
    The police subsequently developed an unspecified
    lead and, as a result of that information, were able to
    obtain a warrant for a sample of the defendant’s DNA
    to test against several samples collected from the crime
    scene. Those tests revealed that the defendant and an
    unidentified male were contributors to certain DNA
    profiles developed from the victim’s vaginal swab. On
    September 3, 2003, the defendant, who was eighteen
    years old at the time, was arrested by the police. He
    waived his Miranda4 rights and then was questioned
    at length. Although the defendant initially denied know-
    ing or having sex with the victim, he ultimately gave a
    written confession after being confronted with the
    results of the testing that had been performed on the
    victim’s vaginal swab.5
    The operative information in the present case con-
    tained nine counts, including two counts of capital fel-
    ony; General Statutes (Rev. to 2001) § 53a-54b (5) and
    (6); one count of murder; General Statutes § 53a-54a
    (a); one count of felony murder; General Statutes (Rev.
    to 2001) § 53a-54c; one count of sexual assault in the
    first degree; General Statutes § 53a-70 (a) (1); three
    counts of kidnapping in the first degree; General Stat-
    utes § 53a-92 (a) (2) (A), (B) and (C); and one count
    of burglary in the first degree. General Statutes (Rev.
    to 2001) § 53a-101 (a) (2). The defendant pleaded not
    guilty, and a trial commenced on May 8, 2007.6 On June
    27, 2007, a jury returned a verdict finding the defendant
    guilty on all counts. The trial court subsequently ren-
    dered a judgment of conviction in accordance with the
    jury’s verdict.7 This appeal followed. See footnote 1 of
    this opinion.
    I
    We begin with the defendant’s claim that the state
    violated his right to counsel under the sixth amend-
    ment.8 Pladsen, a jailhouse informant who was incarcer-
    ated with the defendant prior to and during the defen-
    dant’s trial, testified that the defendant had asked him
    to participate in a ruse intended to undermine the credi-
    bility of Andrew Weaver, a detective with the Hartford
    Police Department. The defendant sought to suppress
    that testimony pursuant to Massiah v. United States,
    
    supra,
     
    377 U.S. 201
    , and its progeny, arguing that Plad-
    sen had deliberately elicited incriminating statements
    while acting as an agent of the police. On appeal, the
    defendant claims that the trial court incorrectly con-
    cluded that no agency relationship existed and, as a
    result, improperly denied his motion to suppress Plad-
    sen’s testimony pursuant to Massiah. In response, the
    state contends that the trial court’s conclusion was cor-
    rect, and, therefore, the defendant’s motion to suppress
    was properly denied. We agree with the defendant.
    The record reveals the following additional undis-
    puted facts relating to Pladsen’s involvement in the
    present case. On December 27, 2006, Pladsen wrote a
    letter to Weaver. At that time, Pladsen was an inmate at
    Northern Correctional Institution (Northern) in Somers
    and interacted with the defendant on a regular basis.9
    That letter stated, among other things, that Pladsen had
    information about the defendant that could prove ‘‘very
    useful’’ to Weaver, that Pladsen was scheduled to be
    paroled to serve a separate fifty-five year sentence in
    Iowa, and that Pladsen would be extradited back to
    Connecticut after serving that sentence. The letter refer-
    enced certain individuals involved in another criminal
    case that was pending against the defendant and
    included the following invitation: ‘‘You want my help,
    come [and] see me [and] we’ll talk.’’ The letter stated
    that Pladsen was not seeking a transfer to another cor-
    rectional institution, a sentence reduction, or ‘‘anything
    like that.’’
    In response to Pladsen’s letter, Weaver scheduled a
    meeting that was held in a private office at Northern
    on January 5, 2007. During that meeting, Weaver and
    Pladsen spoke specifically about the defendant’s
    involvement in the victim’s death. Pladsen did not con-
    vey any detailed information but, instead, provided only
    general facts to show that ‘‘he might know something.’’
    At some point during that conversation, Weaver
    inquired whether Pladsen would be willing to wear a
    wire.10 Pladsen initially expressed some concern but
    ultimately agreed. Pladsen also asked whether he would
    benefit in some way from providing information about
    the defendant.11 Weaver said that any ‘‘deals’’ or plans
    to use a wire would have to be approved by the Office
    of the State’s Attorney and that he would get back to
    Pladsen.12 Pladsen said that he understood. Weaver then
    added that the police are ‘‘always interested’’ in gather-
    ing information about criminal matters from reliable
    sources and that he would be willing to listen to, and
    subsequently verify, anything Pladsen had to say.
    Weaver also made Pladsen generally aware that the
    defendant’s trial was imminent and that the Office of the
    State’s Attorney would be told any relevant information.
    Weaver then told Pladsen that, because of his criminal
    record and history, his word ‘‘[w]asn’t going to be good
    enough . . . .’’
    The Office of the State’s Attorney subsequently
    advised Weaver to take no further action with respect
    to Pladsen. As a result, Weaver did not follow up with
    Pladsen as Weaver had promised. Over the months that
    followed, a corrections officer contacted Weaver on a
    few occasions to let him know that Pladsen wanted to
    speak again. On May 17, 2007, Weaver asked a correc-
    tions officer to inform Pladsen that ‘‘nothing . . . had
    changed’’ and that Weaver would try to be in touch
    again soon.13
    Pladsen testified that he eventually told the defendant
    about the meeting with Weaver. Pladsen stated that the
    defendant had then made a plan for Pladsen to feed
    Weaver information about the case so that the state
    would call Pladsen as a witness. According to Pladsen,
    he was then supposed to lie on the stand and say that
    he had received that information from Weaver. Pladsen
    testified that he asked the defendant to write the infor-
    mation down and that the defendant had created a one
    page note as a result. On May 28, 2007, a few days
    before the state was scheduled to rest its case, Weaver
    received multiple telephone calls indicating that Plad-
    sen wanted to get in touch again. Pladsen testified that
    Weaver called him the following day to ask what infor-
    mation Pladsen had. Pladsen then read Weaver the note
    over the telephone.14
    The state immediately notified the defense of its
    intention to call Pladsen as a witness and disclosed
    a copy of a five page report by Weaver detailing the
    preceding events. On May 30, 2007, the defendant filed
    a motion seeking to suppress Pladsen’s testimony pur-
    suant to, inter alia, the sixth amendment. The following
    day, the trial court commenced an evidentiary hearing
    outside of the presence of the jury. During that hearing,
    Weaver and Pladsen testified about the nature of their
    conversations and the various events leading up to the
    creation of the note. In particular, Pladsen testified that
    he had acted on his own accord and that Weaver had
    not promised him anything.
    At the close of the evidentiary hearing, the trial court
    orally denied the defendant’s motion to suppress Plad-
    sen’s testimony.15 In a subsequent, written memoran-
    dum of decision, the trial court concluded that Pladsen
    was not acting as an agent of the state. In reaching that
    conclusion, the trial court expressly found Pladsen’s
    testimony to be credible. The trial court reasoned: ‘‘Tes-
    timony demonstrated that Pladsen and Weaver had no
    contact prior to January, 2007, and that Pladsen initiated
    the first contact. There is no evidence to suggest that
    the state, at any point, had a plan to enlist Pladsen’s
    help in obtaining incriminating evidence from the defen-
    dant or had made an agreement with Pladsen to obtain
    such evidence. In fact, all [the] evidence indicates that
    there was no plan or agreement. Likewise, there is no
    evidence to suggest that . . . any . . . law enforce-
    ment agency was involved in the decision to house
    Pladsen near the defendant. Weaver never instructed
    Pladsen to obtain incriminating evidence about the
    defendant but, in fact, told him that any action would
    require prior approval by the [Office of the State’s Attor-
    ney]. Weaver was advised not to pursue the matter
    and never initiated further contact with Pladsen. When
    Weaver later contacted Pladsen, it was only in response
    to multiple messages requesting a return call. In addi-
    tion, Weaver made no promises or offers to Pladsen
    and told him that he had no authority to do so. Finally,
    the defendant continued to discuss the details of his
    case with Pladsen, even after he knew that Pladsen had
    met with Weaver.’’
    After the trial court denied the defendant’s motion
    to suppress, the following evidence was presented to
    the jury. Pladsen testified that he was an inmate at
    Northern, again recounted the defendant’s ruse to dis-
    credit Weaver, and identified a particular exhibit sub-
    mitted by the state as the note that the defendant had
    written.16 Although Pladsen was subjected to extensive
    cross-examination regarding his criminal history, men-
    tal health, and possible motives, he testified that he
    was receiving absolutely no benefit in exchange for his
    testimony. The state then presented testimony from a
    handwriting expert, Greg Kettering, who concluded that
    there was ‘‘no doubt’’ that the note shared a common
    authorship with known samples of the defendant’s writ-
    ing. The note was then admitted into evidence as a full
    exhibit over the defendant’s objection. The contents of
    that note stated, among other things, that the author
    had ‘‘used the bloody tank top on the floor to strangle
    [the victim], and that’s the murder weapon.’’17
    Pladsen subsequently filed a motion in the Superior
    Court seeking modification of a twenty-five year sen-
    tence he had received for an assault on a corrections
    officer.18 The state consented to a hearing on that
    motion, which was held on December 23, 2016, pursuant
    to General Statutes § 53a-39 (b). At that hearing, the
    state represented that Pladsen’s motion for a sentence
    modification ‘‘was made . . . in the spirit of what
    [Senior Assistant State’s Attorney John] Fahey had indi-
    cated to . . . Pladsen, that [the state] would make the
    court aware of what [Pladsen] had done . . . .’’ See
    footnote 17 of this opinion. Although the state con-
    sented to the hearing, it took no position on whether
    Pladsen’s motion should be granted. After listening to
    testimony from the corrections officer who Pladsen had
    assaulted, the trial court in that case denied Pladsen’s
    motion.
    On appeal, the defendant claims that the trial court
    improperly denied his motion to suppress Pladsen’s
    testimony. Specifically, the defendant claims that his
    sixth amendment right to counsel was violated when
    the state used Pladsen as an agent to deliberately elicit
    incriminating statements. In order to obtain relief on
    such a claim, a defendant must prove the following:
    ‘‘(1) the [s]ixth [a]mendment right to counsel has
    attached; (2) the individual seeking information from
    the defendant is a government agent acting without the
    defendant’s [counsel] being present; and (3) that agent
    deliberately elicit[s] incriminating statements from the
    defendant.’’ (Internal quotation marks omitted.) Hen-

    268 Conn. 781
    , 854, 
    847 A.2d 921
     (2004).
    The defendant’s presentation of this claim, which
    focuses on the question of agency, turns on the follow-
    ing general themes: ‘‘(1) Weaver’s encouragement . . .
    of Pladsen, (2) Pladsen’s agreement to provide evidence
    and wear a wire, and (3) the state’s failure to take any
    action to call off Pladsen . . . .’’ The defendant asserts
    that ‘‘[t]he trial court’s and [the] state’s constrained
    view of agency as requiring explicit instruction, or as
    requiring that the informant adhere to a preexisting
    plan . . . is unsupported . . . [by] the case law’’ and
    that the state ‘‘knew or should have known that Weav-
    er’s interaction with Pladsen created a situation likely
    to induce [the defendant] into unknowingly giving
    uncounseled, incriminating statements to a person who
    had agreed to help the state obtain evidence . . . .’’
    In response, the state argues that the trial court cor-
    rectly concluded that Pladsen was not acting as an agent
    of the government. The state supports this argument
    by pointing to several of the same facts relied on by
    the trial court. Specifically, the state highlights (1) the
    absence of specific plans or instructions, (2) the fact
    that Pladsen appeared to be self-motivated, (3) Weav-
    er’s statement that he could not personally approve
    any plans or deals, and (4) the fact that Weaver never
    followed up with Pladsen after their initial meeting.
    The state concedes, as it must, that the defendant’s
    sixth amendment right to counsel attached well before
    Pladsen’s involvement. See, e.g., Kirby v. Illinois, 
    406 U.S. 682
    , 689–90, 
    92 S. Ct. 1877
    , 
    32 L. Ed. 2d 411
     (1972).
    Likewise, the state advances no argument that Pladsen’s
    actions fell short of deliberate elicitation. See, e.g., Kuh-
    lmann v. Wilson, 
    477 U.S. 436
    , 459, 
    106 S. Ct. 2616
    , 
    91 L. Ed. 2d 364
     (1986). Finally, the state does not claim the
    absence of prejudice or otherwise invoke the harmless
    error doctrine. See, e.g., United States v. Miller, 
    116 F.3d 641
    , 667–69 (2d Cir. 1997), cert. denied, 
    524 U.S. 905
    , 
    118 S. Ct. 2063
    , 
    141 L. Ed. 2d 140
     (1998), and cert.
    denied sub nom. Arroyo v. United States, 
    524 U.S. 905
    ,
    
    118 S. Ct. 2063
    , 
    141 L. Ed. 2d 140
     (1998). Thus, the sole
    issue with respect to this claim on appeal is whether
    Pladsen was acting as an agent of the state when he
    elicited incriminating statements from the defendant.
    ‘‘It is well settled that, [w]hen reviewing a trial court’s
    denial of a motion to suppress, [a] finding of fact will
    not be disturbed unless it is clearly erroneous in view
    of the evidence and pleadings in the whole record
    . . . . [W]hen a question of fact is essential to the out-
    come of a particular legal determination that implicates
    a defendant’s constitutional rights . . . and the credi-
    bility of witnesses is not the primary issue, our custom-
    ary deference to the trial court’s factual findings is
    tempered by a scrupulous examination of the record
    to ascertain that the trial court’s factual findings are
    supported by substantial evidence.’’ (Internal quotation

    tional context, is primarily a question of fact . . . .’’

     (1985). Nonetheless, to the extent
    that the resolution of that question ‘‘calls for application
    of the controlling legal standard to the historical facts,’’
    it ‘‘presents a . . . question of law . . . which [this
    court reviews] de novo.’’19 (Internal quotation marks
    omitted.) State v. Castillo, 
    329 Conn. 311
    , 322–23, 
    186 A.3d 672
     (2018). Such a review ‘‘is not limited to the
    facts the trial court actually found in its decision on
    the defendant’s motion to suppress. Rather, [this court]
    may also consider undisputed facts established in the
    record, including the evidence presented at trial.’’ Id.,
    340 (D’Auria, J., dissenting). ‘‘[I]n particular, [this
    court] must take account of any undisputed evidence
    that does not support the trial court’s ruling in favor
    of the state but that the trial court did not expressly
    discredit.’’ State v. Edmonds, 
    323 Conn. 34
    , 39, 
    145 A.3d 861
     (2016).
    ‘‘[T]he United States Supreme Court has held that a
    state violates the sixth amendment when, acting
    through an undisclosed agent, it ‘deliberately elicit[s]’
    incriminating statements from an accused ‘after he [has]
    been indicted’ and his right to counsel has attached.’’
    State v. Swinton, supra, 
    268 Conn. 855
    , quoting Massiah
    v. United States, supra, 
    377 U.S. 206
    . The general nature
    of this constitutional duty is clear: ‘‘[T]he [s]tate [has]
    an affirmative obligation to respect and preserve the
    accused’s choice to seek [the] assistance [of counsel].’’
    (Emphasis added.) Maine v. Moulton, 
    474 U.S. 159
    , 171,

    88 L. Ed. 2d 481
     (1985).20
    Cases from the United States Supreme Court estab-
    lishing this line of sixth amendment jurisprudence do
    not directly address the question of agency. A review
    of those decisions does, however, provide necessary
    context. In Massiah v. United States, supra, 
    377 U.S. 202
    –203, law enforcement officers installed a radio
    transmitter inside of a vehicle belonging to a cooperat-
    ing codefendant. While the defendant in that case was
    free on bail, he made incriminating statements inside
    of the vehicle that were later admitted into evidence
    over his objection at trial. Id., 203. The Supreme Court
    concluded that these facts amounted to an indirect
    interrogation and that federal agents, therefore, had
    violated the sixth amendment.21 Id., 206.
    Like the present case, United States v. Henry, 
    447 U.S. 264
    , 
    100 S. Ct. 2183
    , 
    65 L. Ed. 2d 115
     (1980), involves
    government interactions with a jailhouse informant. In
    that case, federal law enforcement officers contacted
    an inmate who previously had been paid for providing
    information. 
    Id., 266, 270
    . That informant indicated that
    he had been assigned to the same cellblock as the defen-
    dant and several other federal prisoners. 
    Id., 266
    . ‘‘The
    [officer] told him to be alert to any statements made
    by the federal prisoners, but not to initiate any conversa-
    tion with or [to] question [the defendant] regarding the
    [crime at issue].’’ 
    Id.
     Notwithstanding these instruc-
    tions, the informant subsequently engaged the defen-
    dant in a series of conversations about the crime at
    issue, which caused the defendant to make certain
    incriminating statements. 
    Id., 267
    . The informant
    recounted those statements at trial, and the defendant
    subsequently was convicted. 
    Id.
     The government argued
    on appeal that, although the informant had asked the
    defendant questions, no sixth amendment violation
    occurred because the informant had disobeyed instruc-
    tions. 
    Id.,
     269–71. The Supreme Court rejected that argu-
    ment, concluding that, because of the informant’s his-
    tory and proximity to the defendant, the officer ‘‘must
    have known that such propinquity likely would lead to
    that result.’’ 
    Id., 271
    . The court then recounted ‘‘the
    powerful psychological inducements’’ attendant to con-
    finement: ‘‘[T]he mere fact of custody imposes pres-
    sures on the accused; confinement may bring into play
    subtle influences that will make him particularly sus-
    ceptible to the ploys of undercover [g]overnment
    agents.’’ 
    Id., 274
    . On these grounds, the court concluded
    that the government had violated the defendant’s consti-
    tutional rights by ‘‘intentionally creating a situation
    likely to induce [the defendant] to make incriminating
    statements without the assistance of counsel . . . .’’22
    
    Id., 274
    .
    Finally, in Maine v. Moulton, 
    supra,
     
    474 U.S. 159
    ,
    a cooperating codefendant wore a wire to a meeting
    requested by the defendant. 
    Id., 164
    . As in Henry, the
    informant was affirmatively instructed not to question
    the defendant. 
    Id., 165
    . Notwithstanding that instruc-
    tion, the informant prompted the defendant to make
    certain incriminating statements. 
    Id., 166
    . Some of those
    statements were admitted at trial, and the defendant
    subsequently was convicted. 
    Id., 167
    . Before examining
    the facts of the case before it, the court characterized
    the right at issue as follows: ‘‘Once the right to counsel
    has attached and been asserted, the [s]tate must of
    course honor it. This means more than simply that the
    [s]tate cannot prevent the accused from obtaining the
    assistance of counsel. The [s]ixth [a]mendment also
    imposes on the [s]tate an affirmative obligation to
    respect and preserve the accused’s choice to seek this
    assistance. We have on several occasions been called
    upon to clarify the scope of the [s]tate’s obligation in
    this regard, and have made clear that, at the very least,
    the prosecutor and police have an affirmative obligation
    not to act in a manner that circumvents and thereby
    dilutes the protection afforded by the right to counsel.’’23
    (Footnote omitted.) 
    Id.,
     170–71.
    In Moulton, the state advanced an argument on
    appeal that the sixth amendment had not been violated
    because the meeting had been initiated by the defendant
    rather than by the state. 
    Id., 174
    . The Supreme Court
    rejected that argument, concluding that the defendant
    had an affirmative right ‘‘to rely on counsel as a
    ‘medium’ between him and the [s]tate.’’ 
    Id., 176
    ; see
    also 
    id.,
     170–71 n.6. Thus, the court concluded that
    ‘‘knowing exploitation by the [s]tate of an opportunity
    to confront the accused without counsel being present
    is as much a breach of the [s]tate’s obligation not to
    circumvent the right to the assistance of counsel as is
    the intentional creation of such an opportunity. Accord-
    ingly, the [s]ixth [a]mendment is violated when the
    [s]tate obtains incriminating statements by knowingly
    circumventing the accused’s right to have counsel pres-
    ent in a confrontation between the accused and a state
    agent.’’ 
    Id., 176
    . As it had in Henry, the court then held
    that this standard had been met, concluding that, in
    light of the undisputed facts, the state ‘‘must have
    known’’ that the informant would elicit incriminating
    statements. 
    Id., 177
    .
    Some general principles can be drawn from these
    Supreme Court cases. First, although the state’s affirma-
    tive obligation primarily requires it to refrain from tak-
    ing action, it does not follow that a court conducting
    a sixth amendment analysis must ignore opportunities
    for the state that came to pass by chance. Thus, the
    court found a constitutional violation in United States v.
    Henry, 
    supra,
     
    447 U.S. 268
    , even though the informant’s
    housing in the same cellblock as the defendant in that
    case had not been prearranged by the government. The
    fact that the defendant requested the meeting in Maine
    v. Moulton, 
    supra,
     
    474 U.S. 174
    –76, likewise did not
    preclude a constitutional violation. Second, because of
    the pressures attendant to physical custody, the risk of
    infringement of the right to counsel is more acute in
    the jailhouse setting. See United States v. Henry, 
    supra, 274
    . Third, a rule requiring direct proof that the govern-
    ment knowingly violated the defendant’s right to coun-
    sel sets the bar too high to protect that right. See Maine
    v. Moulton, 
    supra,
     176 n.12; see also State v. Diaz, 
    302 Conn. 93
    , 120, 
    25 A.3d 594
     (2011) (Palmer, J., concur-
    ring) (‘‘[I]t is difficult for a defendant to demonstrate
    the existence of an ‘implicit understanding’ between
    the state and an informer that the latter will, in fact,
    receive a benefit for his or her testimony. In fact, it is
    likely to be impossible for the defendant to demonstrate
    the existence of such an understanding between the
    state and its witness.’’ (Emphasis in original.)). It will
    suffice to show that, in light of the totality of the circum-
    stances, the state ‘‘must have known’’ that its actions
    likely would lead to the deliberate elicitation of incrimi-
    nating statements.24 United States v. Henry, 
    supra, 271
    .
    Although these United States Supreme Court cases
    explored the bounds of deliberate elicitation, lower
    courts examining the question of agency—including
    this court—have frequently looked to those decisions
    for guidance. See, e.g., State v. Alexander, supra, 
    197 Conn. 184
    ; see also Ayers v. Hudson, 
    623 F.3d 301
    ,
    310–16 (6th Cir. 2010) (applying ‘‘must have known’’
    standard from Henry and invoking state’s affirmative
    obligation from Moulton in case in which deliberate
    elicitation was conceded by governemnt); Randolph v.
    People,

    , 1144 (9th Cir. 2004) (‘‘Henry
    makes clear that it is not the government’s intent or
    overt acts that are important; rather, it is the ‘likely
    . . . result’ of the government’s acts’’); Matteo v. Super-
    intendent, SCI Albion,

    The United States Supreme Court has yet to articulate
    a test for determining agency under Massiah. Other
    courts, however, have confronted that question directly.
    Decisions of this court, in particular, provide some ini-
    tial instruction in this regard. ‘‘There is no [bright-line]
    test for determining when a private citizen is acting as
    an agent of the police.’’ State v. Alexander, supra, 
    197 Conn. 183
    . ‘‘The existence of an agency relationship
    . . . turns upon a number of factual inquiries into the
    extent of police involvement with the informant. Those
    inquiries include the following: whether the police have
    promised the informant a reward for his cooperation
    or whether he is self-motivated . . . whether the police
    have asked the informant to obtain incriminating evi-
    dence and placed him in a position to receive it . . .
    and whether the information is secured as part of a
    government initiated, [preexisting] plan.’’ (Internal quo-
    tation marks omitted.) State v. Swinton, supra, 
    268 Conn. 855
    –56; accord State v. Marshall, 
    882 N.W.2d 68
    ,
    91 (Iowa 2016) (‘‘[I]t seems clear . . . that agency
    under Massiah does not rely too heavily on traditional
    principles of private contract or agency law, but instead
    seems closer to the doctrine of state action. The ques-
    tion, for constitutional purposes, is whether the actions
    of an informant may be fairly attributed to the state.’’),
    cert. denied,      U.S.    , 
    137 S. Ct. 829
    ,

     (2017).
    The facts underlying State v. Swinton, supra, 
    268 Conn. 781
    , serve as a useful starting point. In that case,
    a jailhouse informant, who previously had provided
    information to the police in unrelated cases, overheard
    the defendant making death threats against certain wit-
    nesses. 
    Id.,
     852–53. The informant later met with the
    police, told them about the defendant’s statements, and
    entered into a formal agreement with the state to serve
    as a ‘‘ ‘listening post.’ ’’ Id., 853. After the informant
    returned to prison, the defendant made further incrimi-
    nating statements. Id. The trial court found that the
    nature of the informant’s relationship had changed
    when he entered into a formal agreement with the
    police. Id., 853–54. Specifically, the trial court found
    that, before the meeting, there was ‘‘no evidence what-
    soever that the police had instructed [the informant] to
    gather information about [the defendant’s] case, about
    crimes in general, or about any other case in particular,
    nor [was] there any evidence that the police had indi-
    cated to [the informant] that he would be rewarded
    in any way by providing information . . . .’’ (Internal
    quotation marks omitted.) Id., 857. This court agreed,
    noting that, although the informant had assisted the
    police previously and ‘‘had some expectation that he
    would benefit from providing information . . . there
    was no evidence that the government had directed or
    steered the informant toward the defendant.’’ Id., 858.
    Neither the trial court in that case nor this court, how-
    ever, had any difficulty concluding that the informant
    was a government agent after entering into a formal
    agreement with the state.26 Id., 859.
    Cases from other jurisdictions help to draw the line
    between entrepreneur and agent more precisely. The
    United States Court of Appeals for the Second Circuit,27
    for example, has held that ‘‘[a]n informant becomes a
    government agent vis-à-vis a defendant when the infor-
    mant is instructed by the police to get information about
    [that] particular defendant.’’ (Internal quotation marks
    omitted.) United States v. Whitten, 
    610 F.3d 168
    , 193
    (2d Cir. 2010); see also United States v. LaBare, 
    191 F.3d 60
    , 65 (1st Cir. 1999); Moore v. United States, 
    178 F.3d 994
    , 999 (8th Cir.), cert. denied,

    , 
    120 S. Ct. 356
    , 
    145 L. Ed. 2d 278
     (1999).28
    Other courts have looked at the government’s rela-
    tionship with the informant more broadly and examined
    the record for, among other things,29 evidence of prom-
    ises or the provision of some benefit. See Thompson v.
    Davis, 
    916 F.3d 444
    , 455 (5th Cir. 2019) (‘‘[t]o determine
    whether an informant was a government agent for pur-
    poses of a Massiah claim, the court asks whether the
    informant was promised, reasonably led to believe, or
    actually received a benefit in exchange for soliciting
    information from the defendant . . . and whether he
    acted pursuant to instructions from the [s]tate, or other-
    wise submitted to the [s]tate’s control’’); United States
    v. Johnson, 
    supra,
     
    4 F.3d 910
    –11 (agency may be sup-
    ported by express or implied quid pro quo); see also
    Ayers v. Hudson, 
    supra,
     
    623 F.3d 311
     (‘‘although direct
    written or oral instructions by the [s]tate to a jailhouse
    informant to obtain evidence from a defendant would
    be sufficient to demonstrate agency, it is not the only
    relevant factor’’); Depree v. Thomas, 
    supra,
     
    946 F.2d 793
    –94 (‘‘[t]here is, by necessity, no bright-line rule for
    determining whether an individual is a government
    agent for purposes of the sixth amendment right to
    counsel’’).
    Courts have reached a general consensus that an
    agency relationship may be established through either
    implicit or explicit conduct. See State v. Marshall,
    supra, 
    882 N.W.2d 91
     (citing cases). Indeed, requiring a
    defendant to produce admissible evidence of an explicit
    agreement, promise, or instruction as a predicate to
    relief would substantially diminish the protections
    afforded under Massiah. See Ayers v. Hudson, 
    supra,
    623 F.3d 312
     (‘‘[t]o hold otherwise would allow the
    [s]tate to accomplish ‘with a wink and a nod’ what it
    cannot do overtly’’). Requiring proof of formal arrange-
    ments is also in tension with the affirmative obligation
    to protect a defendant’s right to counsel imposed by the
    United States Supreme Court. See Maine v. Moulton,
    
    supra,
     
    474 U.S. 171
    .
    The trial court in the present case correctly deter-
    mined that the record does not evince an express or
    formal agreement between Pladsen and Weaver. How-
    ever, this is also not a case in which the state met
    with a jailhouse informant only after the incriminating
    statements had been elicited. See, e.g., State v. Swinton,
    supra, 
    268 Conn. 857
    . Accordingly, we must determine
    whether Pladsen’s conduct after meeting with Weaver
    was, in light of all the facts presented, fairly attributable
    to the state. See United States v. Henry, 
    supra,
     
    447 U.S. 270
    ; State v. Marshall, supra, 
    882 N.W.2d 91
    . Although
    the question is a close one in this case, we believe that,
    on balance, Pladsen’s efforts to procure incriminating
    statements from the defendant during the course of the
    underlying trial were not the result of mere ‘‘luck or
    happenstance . . . .’’ Maine v. Moulton, 
    supra,
     
    474 U.S. 176
    . Rather, we conclude that those efforts are fairly
    attributable to the state.
    First, the meeting between Pladsen and Weaver
    placed a significant emphasis on what useful informa-
    tion Pladsen might obtain as the result of his future
    assistance. Indeed, Pladsen did not convey any informa-
    tion of importance to Weaver during their initial meeting
    at Northern. Instead, the two discussed the possibility
    that Pladsen could elicit, and perhaps record, addi-
    tional incriminating statements from the defendant at
    some later point in time. Although the state is correct
    to note that Weaver conditioned any formal plans on
    approval by the Office of the State’s Attorney, the con-
    tent of this particular conversation indicates, at the very
    least, that the prospect of such assistance would be
    considered.
    Second, the meeting at Northern appears to have
    focused Pladsen’s efforts on producing a particular type
    of evidence. Pladsen’s letter to Weaver offered to pro-
    vide information against the defendant but referenced
    only unrelated criminal charges.30 During the meeting
    that followed, Weaver and Pladsen expressly discussed
    the defendant’s involvement in the victim’s death.
    Weaver asked Pladsen if he would be comfortable wear-
    ing a wire, plainly stated that the police were ‘‘always
    interested’’ in verifiable information from reliable
    sources, and then left Pladsen with his contact informa-
    tion. In this context, one could readily infer that the
    state was principally interested in objectively verifiable
    forms of evidence regarding the defendant’s involve-
    ment in this particular case, such as a recording or
    writing. Although Weaver made no explicit requests
    during this meeting, the handwritten note that Pladsen
    ultimately produced during the state’s case-in-chief mir-
    rored those requirements precisely.31
    Third, Pladsen clearly sought assurance from Weaver
    that a benefit would be made available in exchange for
    his cooperation. See footnote 11 of this opinion. Weaver
    said that he could not personally make any promises,
    but his response (1) informed Pladsen that the Office
    of the State’s Attorney would have to approve any ‘‘deals,’’
    and (2) made Pladsen ‘‘generally aware’’ of the fact that
    ‘‘any information received’’ would be conveyed to the
    Office of the State’s Attorney. Weaver said that he would
    be willing to listen to anything Pladsen had to say, and
    Pladsen said that he understood. Although Weaver did
    not connect these dots in explicit terms, the presence
    of such express language is not necessarily required
    for the reasons stated previously. See State v. Arroyo,
    
    292 Conn. 558
    , 568, 
    973 A.2d 1254
     (2009) (‘‘the expecta-
    tion of a [r]eward for testifying is a systemic reality . . .
    even where the informant has not received an explicit
    promise of a reward’’ (citation omitted; internal quota-
    tion marks omitted)), cert. denied, 
    559 U.S. 911
    , 
    130 S. Ct. 1296

    175 L. Ed. 2d 1086
     (2010); see also McBeath v.
    Commonwealth, 
    244 S.W.3d 22
    , 33–34 (Ky. 2007) (there
    was some evidence that informant acted with expecta-
    tion of future benefit when officer responded to infor-
    mant’s inquiry by stating ‘‘ ‘[t]hat’s up to the prosecu-
    tor’ ’’).
    The fact that the state did not object to Pladsen’s
    attempt to pursue a modification of his twenty-five year
    sentence is also relevant.32 As we noted previously, Plad-
    sen’s testimony indicates that this precise exchange was
    discussed during his meeting with Weaver at Northern.
    Indeed, the state does not appear to contest that, as a
    factual matter, Pladsen ultimately was permitted to
    seek a sentence modification as the result of his assis-
    tance in the present case. Although Pladsen’s efforts in
    that regard ultimately proved unsuccessful, the state’s
    forbearance of its unilateral right to veto such a pro-
    ceeding in its entirety pursuant to § 53a-39 (b) provided
    something objectively valuable in exchange for Plad-
    sen’s cooperation. Cf. United States v. Brink, 
    39 F.3d 419
    , 423 n.5 (3d Cir. 1994). In the sixth amendment
    context, the provision of such an actual benefit in
    exchange for an informant’s cooperation serves as at
    least some evidence of agency. See United States v.
    Johnson, 
    supra,
     
    4 F.3d 910
    –11; United States v. York,
    
    933 F.2d 1343
    , 1358 (7th Cir.) (overruled on other
    grounds by Wilson v. Williams,

    103 S. Ct. 465
    , 
    74 L. Ed. 2d 614
     (1982).
    Finally, the sixth amendment concerns in the present
    case must be viewed in light of the defendant’s confine-
    ment. As the United States Supreme Court has noted,
    ‘‘the mere fact of custody imposes pressures on the
    accused; confinement may bring into play subtle influ-
    ences that will make him particularly susceptible to
    the ploys of undercover [g]overnment agents.’’ United
    States v. Henry, 
    supra,
     
    447 U.S. 274
    ; see Matteo v. Super-
    intendent, SCI Albion, 
    supra,
     
    171 F.3d 895
    ; see also
    Illinois v. Perkins, 
    496 U.S. 292
    , 307, 
    110 S. Ct. 2394
    , 
    110 L. Ed. 2d 243
     (1990) (Marshall, J., dissenting) (‘‘Custody
    works to the [s]tate’s advantage in obtaining incriminat-
    ing information. The psychological pressures inherent
    in confinement increase the suspect’s anxiety, making
    him likely to seek relief by talking with others.’’). In
    this context, ‘‘the government has long been on notice
    that the use of prison informants risks treading on the
    constitutional rights of an accused . . . .’’ United
    States v. Stevens, 
    83 F.3d 60

     (1996).33
    To summarize, Weaver met with Pladsen and
    expressed an interest in obtaining verifiable evidence of
    incriminating statements from this particular defendant
    regarding this particular case. Although there was no
    ‘‘agreement,’’ ‘‘contract,’’ ‘‘mutual understanding,’’ or
    ‘‘meeting of the minds,’’ the two expressly discussed
    Pladsen’s desire for a benefit in exchange for his cooper-
    ation in the present case, and, in fact, the state actually
    provided such a benefit to Pladsen after the desired
    evidence was produced. Although the record does not
    evince any particular ‘‘plan’’ or ‘‘instruction,’’ Weaver
    knew from the initial letter that Pladsen had strong
    incentives to cooperate as the result of his incarceration
    and consecutive sentences, had already gained the
    defendant’s trust, and was in a uniquely strong position
    to question the defendant at length. After Weaver told
    Pladsen that he was interested in hearing new evidence
    relating to the victim’s death—by, for example, sug-
    gesting the use of a wire—additional control would
    have been superfluous. We conclude that the state
    either knew or should have known that such a conversa-
    tion was likely to end in further deliberate elicitation.34
    Notwithstanding the eventual likelihood of such
    efforts by Pladsen, very little was done to protect the
    defendant’s sixth amendment rights. During the meet-
    ing at Northern, Weaver could have expressly instructed
    Pladsen to cease deliberately eliciting information from
    the defendant or to avoid conversations regarding the
    present case until the Office of the State’s Attorney
    could provide guidance on how to proceed. Although
    the Office of the State’s Attorney ultimately instructed
    Weaver not to pursue this avenue, that fact was never
    communicated to Pladsen. Weaver’s general admoni-
    tion that any plans or deals would have to be formally
    approved, the impact of which is unclear; see footnote
    12 of this opinion; was ‘‘a far cry from the express
    and appropriate warnings’’ that should have been given.
    State v. Howell, Superior Court, judicial district of New
    Britain, Docket No. CR-05-222048-S (January 30, 2007)
    (Sheldon, J.).35 On the basis of the record presently
    before us, we simply cannot conclude that the state
    has satisfied its affirmative obligation under Massiah
    and its progeny to respect and preserve the defendant’s
    invocation of his constitutional right to counsel. See
    Maine v. Moulton, 
    supra,
     
    474 U.S. 171
    .
    The trial court’s remaining findings of historical fact
    do not alter this analysis. Although Pladsen was housed
    with the defendant by chance, that same fact was of
    no moment in United States v. Henry, 
    supra,
     
    447 U.S. 268
    . Likewise, the fact that Pladsen initiated contact
    with the police does not diminish the possibility that
    the state subsequently took advantage of the opportu-
    nity that contact created. See Maine v. Moulton, 
    supra,
    474 U.S. 176
     (‘‘knowing exploitation by the [s]tate of
    an opportunity to confront the accused without counsel
    being present is as much a breach of the [s]tate’s obliga-
    tion not to circumvent the right to the assistance of
    counsel as is the intentional creation of such an oppor-
    tunity’’). Finally, although the defendant’s subjective
    knowledge that Pladsen was speaking with Weaver may
    be relevant to an analysis of waiver; see United States
    v. Henry, 
    supra, 273
    ; the question of agency must be
    resolved by an examination of the facts relating to the
    nature of the relationship between the state and the
    defendant’s interrogator.36
    For the foregoing reasons, we conclude that a scrupu-
    lous examination of the undisputed facts contained
    within the record of the present case establishes that
    the defendant has satisfied his burden of demonstrating
    the existence of an agency relationship under Massiah.
    The trial court’s denial of the motion to suppress Plad-
    sen’s testimony was, therefore, improper. As a result,
    the defendant is entitled to a new trial.
    II
    The defendant next claims that there is insufficient
    evidence that he had ‘‘remain[ed] unlawfully’’ in the
    victim’s apartment, as required to sustain a conviction
    on the charge of burglary in the first degree under
    General Statutes (Rev. to 2001) § 53a-101 (a) (2).37 The
    defendant’s sole argument in support of this claim is
    that State v. Allen, 
    216 Conn. 367
    , 382, 
    579 A.2d 1066
    (1990), should be overruled because it ‘‘impermissibly
    merges the [element] of remaining unlawfully and the
    intent to commit a crime’’ by holding that proof of any
    indoor criminal act satisfies both elements. The state
    agrees with the defendant’s reading of Allen but never-
    theless argues that its holding should be allowed to
    stand as settled law. We conclude, however, that the
    holding of that case stands for the far narrower proposi-
    tion that the state may prove an unlawful remaining by
    producing evidence that a defendant has engaged in
    conduct that was likely to terrorize occupants. State v.
    Allen, supra, 382–84. For the reasons that follow, we
    decline the defendant’s invitation to overrule that hold-
    ing.
    Although this claim is framed as a question of eviden-
    tiary sufficiency, the issue presented relates to the
    proper construction of this state’s burglary statutes and,
    more particularly, the scope of the phrase ‘‘enters or
    remains unlawfully . . . .’’ General Statutes (Rev. to
    2001) § 53a-101 (a). The question of whether our con-
    struction of that statutory language in Allen should be
    overruled raises an issue of law that is subject to plenary
    review. See, e.g., State v. Salamon, 
    287 Conn. 509
    , 529,
    
    949 A.2d 1092
     (2008); see also, e.g., Spiotti v. Wolcott,
    
    326 Conn. 190
    , 195, 
    163 A.3d 46
     (2017).
    ‘‘The doctrine of stare decisis counsels that a court
    should not overrule its earlier decisions unless the most
    cogent reasons and inescapable logic require it.’’ (Inter-
    nal quotation marks omitted.) Commission on Human
    Rights & Opportunities v. Sullivan, 
    285 Conn. 208
    , 216,
    
    939 A.2d 541
     (2008). ‘‘In evaluating the force of stare
    decisis, our case law dictates that we should be espe-
    cially wary of overturning a decision that involves the
    construction of a statute. . . . When we construe a
    statute, we act not as plenary lawgivers but as surro-
    gates for another policy maker, [that is] the legislature.
    In our role as surrogates, our only responsibility is to
    determine what the legislature, within constitutional
    limits, intended to do. Sometimes, when we have made
    such a determination, the legislature instructs us that
    we have misconstrued its intentions. We are bound by
    the instructions so provided. . . . More often, how-
    ever, the legislature takes no further action to clarify
    its intentions. Time and again, we have characterized
    the failure of the legislature to take corrective action
    as manifesting the legislature’s acquiescence in our con-
    struction of a statute. . . . Once an appropriate inter-
    val to permit legislative reconsideration has passed
    without corrective legislative action, the inference of
    legislative acquiescence places a significant jurispru-
    dential limitation on our own authority to reconsider
    the merits of our earlier decision.’’ (Internal quotation
    marks omitted.) 
    Id.,
     216–17.
    We begin by setting forth the relevant statutory lan-
    guage. General Statutes (Rev. to 2001) § 53a-101 (a) (2)
    provides in relevant part that ‘‘[a] person is guilty of
    burglary in the first degree when he enters or remains
    unlawfully in a building with intent to commit a crime
    therein and . . . in the course of committing the
    offense, he intentionally, knowingly or recklessly
    inflicts or attempts to inflict bodily injury on anyone.’’38
    General Statutes (Rev. to 2001) § 53a-100 (b), in turn,
    provides that ‘‘[a] person ‘enters or remains unlawfully’
    in or upon premises when the premises, at the time of
    such entry or remaining, are not open to the public and
    when the actor is not otherwise licensed or privileged
    to do so.’’39
    In State v. Allen, supra, 
    216 Conn. 379
    , this court
    considered whether there was sufficient evidence to
    support a conviction of burglary in the first degree. In
    addressing that claim, we began by noting that the
    phrase ‘‘licensed or privileged’’ was ‘‘meant as a unitary
    phrase, rather than as a reference to two separate con-
    cepts.’’ (Internal quotation marks omitted.) 
    Id., 380
    .
    Drawing from a previous Appellate Court decision, we
    explained: ‘‘A license in real property is defined as a
    personal, revocable, and unassignable privilege, con-
    ferred either by writing or parol, to do one or more
    acts on land without possessing any interest therein.’’
    (Emphasis in original; internal quotation marks omit-
    ted.) 
    Id.,
     quoting State v. Grant, 
    6 Conn. App. 24
    , 29,
    
    502 A.2d 945
     (1986).
    In Allen, the evidence showed that the defendant had
    entered the subject premises, a condominium, with an
    accomplice who had a key. State v. Allen, supra, 
    216 Conn. 381
    . The defendant was then led upstairs where
    the occupant of the home was tied up, unclothed, and
    gagged. 
    Id.,
     381–82. Although the victim looked to the
    defendant for assistance, none was given. 
    Id.
     Instead,
    the defendant stole some of the victim’s property and
    watched while his accomplice choked the victim. 
    Id., 382
    . On the basis of these facts, this court rejected the
    defendant’s claim that there was insufficient evidence
    of an unlawful remaining. 
    Id.
     Specifically, we reasoned
    that, ‘‘even if the defendant initially entered the victim’s
    condominium lawfully, it is clear that consent to remain
    was implicitly withdrawn and thus that the [defendant]
    unlawfully remained within the meaning of the statute.’’
    (Internal quotation marks omitted.) 
    Id.
    In Allen, this court distinguished State v. Thomas,
    
    210 Conn. 199
    , 204, 
    554 A.2d 1048
     (1989), a case that
    involved a convenience store robbery. We indicated
    that the holding of Thomas—namely, that ‘‘a defendant
    does not lose his status as a member of the public by
    manifesting a criminal intent’’—was relevant only in
    cases in which the premises were held ‘‘ ‘open to the
    public’ ’’ and, therefore, did ‘‘not apply to a private
    dwelling that requires the continued consent of its occu-
    pant.’’40 State v. Allen, supra, 
    216 Conn. 383
    –84. We
    then reiterated that the purpose of the statutory phrase
    ‘‘enters or remains unlawfully’’ is ‘‘to make clear that
    only the kind of entry or remaining [that] is likely to
    terrorize occupants is prohibited by the crime of bur-
    glary.’’ (Internal quotation marks omitted.) 
    Id., 384
    . In
    Allen, we readily concluded that ‘‘the element of terror
    was present’’ and that ‘‘seeing the victim naked, gagged,
    and tied up on the floor, and seeing [his accomplice]
    threaten, strike and choke the victim while the victim,
    in terror, looked for help, all clearly indicated to the
    defendant that, even if there were consent for his ini-
    tially entering the condominium, it had been [implicitly]
    withdrawn.’’ 
    Id.
    The defendant in the present case suggests that Allen
    ‘‘conflate[s] the elements of intent and unlawful remain-
    ing.’’ Specifically, the defendant asserts that our reason-
    ing in that case implies that ‘‘a person’s license to be
    on the property is revoked simply because he commits
    a crime inside the premises . . . .’’ Put differently, the
    defendant claims that, under Allen, ‘‘every person who
    commits a crime while inside a building also commits
    a burglary . . . .’’ The defendant argues that, instead,
    this court should restrict unlawful remaining to surrep-
    titious conduct.41 In presenting these arguments, the
    defendant relies on case law from other jurisdictions,
    this state’s plain meaning rule, as embodied in General
    Statutes § 1-2z, and various cannons of statutory con-
    struction.
    Neither Allen nor its progeny, however, supports the
    defendant’s interpretation of this court’s reasoning.
    Indeed, that case was expressly dependent on the vic-
    tim’s sense of terror. Broadening the holding of that
    case to reach any indoor criminal act would not only
    dispense with that requirement but also with the need
    for any occupants at all. Although such facts are not
    always required for the commission of a burglary; com-
    pare General Statutes § 53a-102 (a) (occupancy is
    required for burglary in second degree) with General
    Statutes § 53a-101 (a) (3) (occupancy is not required for
    burglary in first degree); or for a finding of an unlawful
    remaining itself; see footnote 40 of this opinion; the
    fact that the defendant’s presence was ‘‘likely to terror-
    ize’’ the victim in Allen was indispensable to our conclu-
    sion that any existing license or privilege to remain
    had been implicitly revoked. (Internal quotation marks
    omitted.) State v. Allen, supra, 
    216 Conn. 384
    .
    This narrower reading of Allen is bolstered by the
    fact that the Appellate Court has consistently restricted
    its application to cases in which the state has presented
    evidence that the defendant engaged in conduct likely
    to terrorize occupants. See, e.g., State v. Marsan, 
    192 Conn. App. 49
    , 53–54, 56–61,

    cited, and our research has not discovered, any appel-
    late authority extending the holding of Allen beyond
    this context.
    The fact that our legislature has declined to express
    any disagreement with this line of cases over the course
    of nearly three decades counsels strongly against over-
    ruling Allen in favor of a more restrictive statutory
    interpretation. See, e.g., Commission on Human Rights
    & Opportunities v. Sullivan, 
    supra,
     
    285 Conn. 216
    –17.
    This is especially true because the legislature has made
    unrelated amendments to the relevant statutory scheme.
    See Stuart v. Stuart, 
    297 Conn. 26
    , 47, 
    996 A.2d 259

    lated amendments in the same statute’’ (internal quota-
    tion marks omitted)). Specifically, our legislature passed
    a series of comprehensive amendments to this state’s
    burglary statutes in 2008 that not only retained the
    phrase ‘‘enters or remains unlawfully’’ in § 53a-101 (a)
    and the existing statutory definition set forth in § 53a-
    100 (b), but also added several new instances of that
    exact same statutory phrase. Public Acts, Spec. Sess.,
    January, 2008, No. 08-1, §§ 1, 2 and 4. We may presume
    that the legislature was aware of Allen and its progeny
    when doing so. See, e.g., R.C. Equity Group, LLC v.
    Zoning Commission, 
    285 Conn. 240
    , 257 n.20, 
    939 A.2d 1122
     (2008).
    The defendant’s various arguments do not warrant
    the opposite result. The defendant, citing § 1-2z, encour-
    ages this court to abandon the existing line of cases
    and to begin the process of statutory construction anew.
    We decline to do so. See, e.g., Kasica v. Columbia, 
    309 Conn. 85
    , 93–94 and n.10, 
    70 A.3d 1
     (2013) (in interpre-
    ting statutory text, this court is bound by our prior
    constructions of statute); Hummel v. Marten Trans-
    port, Ltd., 
    282 Conn. 477
    , 501, 
    923 A.2d 657
     (2007)
    (enactment of § 1-2z did not overrule existing case law).
    Although an argument in favor of overruling established
    precedent may well be strengthened by tension with a
    statute’s plain meaning, we can discern no such conflict
    in the present case. When a building is not open to the
    public, the relevant statutory inquiry turns on whether
    a defendant was ‘‘licensed or privileged’’ to remain.
    General Statutes (Rev. to 2001) § 53a-100 (b). The hold-
    ing of Allen, which merely stated the standard for prov-
    ing the absence of such a license or privilege in a partic-
    ular factual setting, is facially consistent with that
    requirement. Finally, the defendant’s argument that
    Allen results in statutory surplusage because it dis-
    penses with the element of an unlawful entry or
    remaining is logically dependent on the premise that
    any indoor criminal conduct necessarily gives rise to
    an implicit revocation. Because, as we previously indi-
    cated, the holding in Allen extends only to conduct
    by a defendant that is ‘‘likely to terrorize occupants’’;
    (internal quotation marks omitted) State v. Allen, supra,
    
    216 Conn. 384
    ; the distinct elements of the crime of
    burglary remain.
    The defendant is correct that intermediate appellate
    courts in New York have declined to conclude that viop
    lent conduct gives rise to an implicit revocation of a
    defendant’s license or privilege to remain. See People
    v. Bowen, 17 App. Div. 3d 1054, 1055, 
    794 N.Y.S.2d 203
    , appeal denied, 
    5 N.Y.3d 759
    , 
    834 N.E.2d 1264
    , 
    801 N.Y.S.2d 254
     (2005); People v. Konikov, 160 App. Div.
    2d 146, 152–53,

    , 
    564 N.E.2d 680
    , 
    563 N.Y.S.2d 70
     (1990). The
    conclusion reached in Allen, however, is consistent with
    the law in states other than New York. See Davis v.
    State, 
    737 So. 2d 480
    , 484 (Ala. 1999) (‘‘[E]vidence of
    a struggle giving rise to the inference of an unlawful
    remaining is supplied by [the defendant’s] choice to kill
    by a [less than instantaneous] technique of strangula-
    tion and by his use of three nonfatal stab wounds to
    the victim’s lower back. Based on the circumstances
    suggested by the evidence, the jury reasonably could
    have found that [the defendant], from the point at which
    he began committing his criminal acts, ‘remain[ed]
    unlawfully’ in [the victim’s] home with the intent to
    commit a crime.’’); Sparre v. State, 
    164 So. 3d 1183
    , 1200–
    1201 (Fla.) (defendant’s invitation to premises was
    ‘‘effectively rescinded’’ when victim began attempting
    futilely to defend herself from fatal attack), cert. denied,

    State v. Walker, 
    600 N.W.2d 606
    , 610 (Iowa 1999) (vic-
    tim’s begging and resistance to assault amounted to
    implicit revocation of defendant’s license to remain).
    Notwithstanding common origins, modern burglary law
    often differs significantly between jurisdictions. See
    Quarles v. United States,        U.S.     , 
    139 S. Ct. 1872
    ,
    1879, 
    204 L. Ed. 2d 200
     (2019). Such variations are,
    without more, generally insufficient to overcome the
    weighty considerations attendant to stare decisis.42 See,
    e.g., Graham v. Commissioner of Transportation, 
    330 Conn. 400
    , 420, 
    195 A.3d 664
     (2018).
    In light of the foregoing, we decline the defendant’s
    invitation to overrule Allen and its progeny. The defen-
    dant advances no argument on appeal that the conduct
    at issue in the present case was unlikely to terrorize
    the victim. As a result, the defendant’s sufficiency of
    the evidence claim relating to the crime of burglary in
    the first degree must fail.
    III
    Finally, we address the defendant’s claim of instruc-
    tional error because we conclude that the issue of third-
    party culpability is likely to arise on remand. The defen-
    dant contends that a third-party culpability instruction
    was reasonably supported by the evidence relating to
    unidentified male DNA discovered on the victim’s vagi-
    nal swab, her shoulder, and her bedroom doorframe.
    In response, the state argues that this evidence was
    insufficient to support such an instruction.43 Specifi-
    cally, the state argues that this evidence establishes
    only that ‘‘the victim may have socialized, done drugs,
    and had sex with various men in the days preceding
    her death’’ and, therefore, fails to establish a direct
    connection ‘‘between any particular third party and the
    crimes against the victim . . . .’’
    The following additional facts and procedural history
    are relevant to our discussion of this claim. Carll Ladd,
    the supervisor of the DNA section of the state forensic
    laboratory, testified at trial that a particular test had
    indicated that both the defendant and a second, uniden-
    tified male were contributors to DNA on the victim’s
    vaginal swab.44 Ladd also testified that the defendant
    was excluded as a contributor to certain unidentified
    male DNA in saliva discovered on the victim’s shoul-
    der.45 Finally, Ladd testified that the defendant also was
    excluded as a contributor to certain unidentified male
    DNA discovered at the location of a transfer bloodstain
    on the victim’s bedroom doorframe.46 Ladd testified that
    he did not know precisely when any of this male DNA
    was deposited.
    The defendant’s revised request to charge included
    the following proposed instruction regarding evidence
    of third-party involvement: ‘‘You are hereby instructed
    that a defendant may offer proof [that] indicates that
    a third party, and not the defendant, committed some
    of the acts for which the defendant is on trial. The
    defendant must, however, show some evidence which,
    if believed, tends to directly connect a third party to
    said acts. The primary object of the third-party suspect
    testimony is not to prove the guilt of the third party
    but to raise a reasonable doubt about the guilt of the
    defendant. In the present case, you have heard evidence
    concerning the presence of the DNA of a person or
    persons other than [the defendant] and [the victim] at
    the scene of the crime. If that evidence leaves you with
    a reasonable doubt as to [the defendant’s] guilt, you
    must find him not guilty.’’47
    The state objected to this proposed instruction at a
    charging conference held on June 12, 2007. In response,
    defense counsel asserted that such an instruction was
    warranted by ‘‘the forensics’’ proffered at trial, citing
    State v. Cerreta, 
    260 Conn. 251
    , 260–62, 
    796 A.2d 1176
    (2002). After hearing arguments, the trial court con-
    cluded that the defendant had failed to establish entitle-
    ment to a third-party culpability instruction.
    ‘‘In determining whether the trial court improperly
    refused a request to charge, [w]e . . . review the evi-
    dence presented at trial in the light most favorable to
    supporting the . . . proposed charge. . . . A request
    to charge [that] is relevant to the issues of [a] case and
    [that] is an accurate statement of the law must be given.
    . . . If, however, the evidence would not reasonably
    support a finding of the particular issue, the trial court
    has a duty not to submit it to the jury. . . . Thus, a
    trial court should instruct the jury in accordance with
    a party’s request to charge [only] if the proposed instruc-
    tions are reasonably supported by the evidence.’’ (Inter-
    nal quotation marks omitted.) State v. Schovanec, 
    326 Conn. 310
    , 318–19, 
    163 A.3d 581
     (2017). This court has
    previously stated that ‘‘the very standards governing
    the admissibility of [third-party] culpability evidence
    also should serve as the standards governing a trial
    court’s decision of whether to submit a requested [third-
    party] culpability charge to the jury.’’ State v. Arroyo,
    
    284 Conn. 597
    , 608–609, 
    935 A.2d 975
     (2007).
    We note that, although Arroyo did not expressly state
    a particular standard of review for claims of instruc-
    tional error related to third-party culpability, this court
    has previously reviewed such claims under an abuse
    of discretion standard. See State v. Schovanec, supra,

    266 Conn. 364
    ,
    422, 
    832 A.2d 14
     (2003) (‘‘[w]e review a trial court’s
    refusal to give a child credibility instruction for abuse
    of discretion because that instruction is not for the
    statement of any rule of law but for a cautionary com-

    tion on flight, as well as the content of such an instruc-
    tion, if given, should be left to the sound discretion of
    the trial court’’).
    The admissibility of third-party culpability evidence
    is generally ‘‘governed by the rules relating to relevancy.
    . . . Relevant evidence is evidence having any ten-
    dency to make the existence of any fact that is material
    to the determination of the proceeding more probable
    or less probable than it would be without the evidence.
    . . . [E]vidence that establishes a direct connection
    between a third party and the charged offense is rele-
    vant to the central question before the jury, namely,
    whether a reasonable doubt exists as to whether the
    defendant committed the offense. Evidence that [raises]
    only a bare suspicion that a third party, rather than
    the defendant, committed the charged offense [is not]
    relevant to the jury’s determination.’’ (Internal quota-
    tion marks omitted.) State v. Schovanec, supra, 
    326 Conn. 319
    ; see also State v. Baltas, 
    311 Conn. 786
    , 810,
    
    91 A.3d 384
     (2014) (‘‘in explaining the requirement that
    the proffered evidence establish a direct connection to
    a third party, rather than raise merely a bare suspicion
    regarding a third party, we have stated [that] [s]uch
    evidence is relevant, exculpatory evidence, rather than
    merely tenuous evidence of [third-party] culpability’’
    (internal quotation marks omitted)).
    ‘‘[I]n some cases, the location of [physical] evidence
    at a particular crime scene will give rise to a reasonable
    inference that the evidence was left at the scene by a
    perpetrator of the crime, such as when the relationship
    between the evidence and crime scene is close and
    direct . . . .’’ (Citation omitted.) State v. West,

    , 626–27,

    , 
    126 S. Ct. 775
    , 
    163 L. Ed. 2d 601
     (2005). This nexus,
    however, necessarily attenuates with distance. See id.,
    627 (concluding that evidence discovered ‘‘at the
    periphery of the crime scene’’ lacked probative value).
    A comparison of our decisions in Cerreta and West is
    illustrative of this principle.
    In State v. Cerreta, supra, 
    260 Conn. 253
    , this court
    considered a claim that third-party culpability evidence
    was improperly excluded in violation of the defendant’s
    right to present a defense under the sixth and fourteenth
    amendments to the United States constitution. The vic-
    tim in that case, a seventy-four year old woman, died
    from asphyxia after being bound with a sock in her
    mouth. Id., 254. The defendant, who had been charged
    with murder, sought to introduce forensic evidence con-
    nected to the crime scene. Id., 253. Specifically, the
    defendant submitted evidence indicating that hairs
    found on both the victim’s body and the ligatures used
    to bind her had not come from him. Id., 257–59. The
    defendant also sought to introduce evidence that finger-
    prints from a third party had been discovered on various
    personal effects strewn about the victim’s body. Id., 254,
    259. The trial court excluded these pieces of forensic
    evidence on relevancy grounds. Id., 259. On appeal, the
    defendant claimed that the proffered evidence should
    have been admitted because it ‘‘was relevant to the
    question of whether someone [else had] committed the
    crime . . . charged.’’ Id. The state responded by
    arguing, among other things, that the forensic evidence
    stopped short of ‘‘conclusively exonerating the defen-
    dant’’; id., 260; and was irrelevant ‘‘because it was
    impossible to determine exactly when the hair and fin-
    gerprints were left where the police discovered them.’’
    Id., 263.
    This court agreed with the defendant, concluding that
    it could ‘‘discern no reasonable basis for concluding
    that the exculpatory evidence the defendant sought to
    introduce was irrelevant.’’ Id., 262. Specifically, we held
    that ‘‘[e]vidence that a third party’s hair and fingerprints
    were found at the crime scene [raised] more than a
    bare suspicion that someone other than the defendant
    may have committed the crime. Rather, the excluded
    evidence established a direct connection between the
    unidentified source of hair and fingerprints and the
    scene of the murder. Such evidence meets the threshold
    requirement that it directly connect a third party to the
    crime.’’48 Id., 263. We then rejected the state’s arguments
    to the contrary: ‘‘The hair and fingerprints were recov-
    ered not from the periphery of the crime scene but from
    the victim’s body, the ligatures used to bind her hands
    and feet, and the personal effects on and around her
    body. This evidence was central to the only contested
    issue at trial: the identity of the perpetrator. Although
    it may be the case that this evidence would not have
    exonerated the defendant unequivocally, such is not
    the standard for relevance. All that must be shown is
    that the evidence tends to support the conclusion for
    which it is offered, even if it does so only to a slight
    degree.’’ Id.
    By contrast, in State v. West, 
    supra,
     
    274 Conn. 610
    ,
    this court concluded that the trial court did not abuse
    its discretion by excluding certain forensic evidence
    recovered from a crime scene. The defendant in that
    case, who was charged with murder, sought to intro-
    duce evidence eliminating her as the source of unidenti-
    fied latent prints discovered in the victim’s home on a
    second floor bathroom door and on the doorjamb of a
    first floor bedroom. Id., 609, 623. The defendant claimed
    ‘‘that the unidentified . . . [prints were] relevant, and
    therefore admissible, because that evidence established
    that a person or persons other than the defendant were
    present in those areas of [the] home where the intruder
    had gone after entering . . . namely, the second floor
    and the first floor master bedroom.’’ Id., 626. We
    rejected that argument, concluding that the prints could
    have been ‘‘made weeks, months or even years before’’
    the crimes at issue. Id. We noted that, although the
    location of such evidence can ‘‘give rise to a reasonable
    inference that the evidence was left at the scene by
    a perpetrator . . . when the relationship between the
    evidence and crime scene is close and direct,’’ the prints
    at issue in that case ‘‘were located at the periphery of
    the crime scene, where . . . they may have been left
    by any number of invitees . . . .’’ Id., 626–27. We
    remarked that, ‘‘[b]ecause the nexus between the prints
    and the crime scene [was] so attenuated, and because
    there [were] so many likely explanations for the prints
    aside from the mere possibility that they were left by
    an unidentified perpetrator, the evidence of the prints
    [was] lacking in probative value.’’49 Id., 627. Accordingly,
    this court concluded that the trial court did not abuse
    its discretion by excluding the unidentified prints that
    the defendant had sought to admit. Id.
    The evidence forming the basis of the defendant’s
    request for a third-party culpability instruction in the
    present case was, of course, admitted into evidence
    and placed before the jury.50 The trial court’s initial
    decision to admit that evidence does not, however, nec-
    essarily compel the issuance of a third-party culpability
    instruction as a matter of law.51 ‘‘Whether a defendant
    has sufficiently established a direct connection between
    a third party and the crime with which the defendant
    has been charged is necessarily a fact intensive inquiry.’’
    State v. Baltas, supra, 
    311 Conn. 811
    . A trial court must
    make that decision on the basis of the totality of the
    evidence actually admitted at trial. See State v. Mar-
    shall, 
    114 Conn. App. 178
    , 187, 
    969 A.2d 202
     (noting
    fluid nature of trials), cert. denied, 
    292 Conn. 911
    , 
    973 A.2d 661
     (2009).
    In order to determine whether the evidence actually
    admitted during the course of the defendant’s trial would
    have supported a third-party culpability instruction, we
    look to the context surrounding it and the guiding prin-
    ciples set forth in Cerreta and West. See State v. Arroyo,
    supra, 
    284 Conn. 608
    –609. It cannot be said that two of
    the DNA samples found on the victim’s body—namely,
    the samples from her vaginal swab and from the saliva
    on her shoulder—were recovered from the periphery
    of the crime scene. Like the hair in Cerreta, that evi-
    dence was recovered directly from the victim’s body.
    It is important to note that context, and not proxim-
    ity alone, is necessary to establish a direct connection
    between forensic evidence and a third party to the crime.
    In the present case, for example, Ladd gave a ‘‘general
    estimate’’ that the unidentified male DNA found on the
    victim’s vaginal swab could have lasted for up to three
    days. Given this longer time frame, the unidentified
    male DNA on the victim’s vaginal swab, in and of itself,
    would have been insufficient to require a third-party
    culpability instruction as a matter of law. The male DNA
    on the victim’s shoulder, however, would have existed
    for a more limited duration and was not otherwise
    explained by the record. Finally, the unidentified male
    DNA on the doorframe of the victim’s bedroom was
    recovered from a location that was, undisputedly, cov-
    ered in the victim’s blood during the commission of the
    crimes charged. That fact readily distinguishes it from
    the prints on the doorjamb in West.
    The state argues that the evidence of the unidentified
    male DNA discovered at the crime scene was wholly
    irrelevant because ‘‘there was no evidence as to when
    any of that DNA had been deposited or to whom it
    belonged.’’ The fact that both the source of the DNA and
    the exact time that it was deposited remained unknown
    does not, however, require a conclusion that the evi-
    dence was irrelevant. Indeed, this court readily con-
    cluded that the evidence at issue in Cerreta was admissi-
    ble, notwithstanding the absence of proof regarding
    those same facts. See State v. Cerreta, supra, 
    260 Conn. 263
     (‘‘The state took the position . . . that the
    excluded evidence was unreliable, and therefore irrele-
    vant, because it was impossible to determine exactly
    when the hair and fingerprints were left where the
    police discovered them. We find no merit in this argu-
    ment.’’).
    Viewing all of the evidence contained in the record
    in the light most favorable to supporting the proposed
    charge; see, e.g., State v. Schovanec, supra, 
    326 Conn. 318
    ; we conclude that the defendant satisfied the thresh-
    old requirement of establishing a direct connection
    between at least some of the unidentified male DNA
    discovered in the victim’s apartment and the various
    crimes alleged. Because the DNA on the victim’s shoul-
    der and the bedroom doorframe would have reasonably
    supported an instruction on third-party culpability, we
    conclude that the trial court abused its discretion by
    declining to provide such an instruction to the jury.52
    The judgment is reversed and the case is remanded
    for a new trial.
    In this opinion PALMER, McDONALD, D’AURIA,
    KAHN and ECKER, Js., concurred.

    The defendant appealed directly to this court pursuant to General Stat-
    utes § 51-199 (b) (4).
    2
    The defendant has raised more than two dozen additional claims on
    appeal. These claims relate to, inter alia, isolated evidentiary rulings, the
    posttrial discovery of evidence, and certain inadvertent mistakes or omis-
    sions. Still other claims arise from various tactical decisions. In light of the
    information contained in the record and the positions adopted by the parties
    in their briefs, we are unable to conclude that such claims are likely to
    arise on remand. Accordingly, we decline to review those claims in the
    present appeal.

    In accordance with our policy of protecting the privacy interests of the
    victims of sexual assault, we decline to identify the victim or others through
    whom the victim’s identity may be ascertained. See General Statutes § 54-
    86e; see also, e.g., State v. Weatherspoon, 
    332 Conn. 531
    , 536 n.3, 
    212 A.3d 208

    The defendant’s statement indicated that the victim had attacked him
    in the kitchen with a knife. The defendant stated that the resulting struggle
    moved to the bedroom and that the victim had eventually asked, ‘‘[w]hat
    do you want sex?’’ The defendant allegedly said yes and then had unprotected
    sex with the victim. The defendant stated that, after they were done, the
    victim attacked him again with the knife. The defendant stated that he then
    stabbed the victim, that she stopped moving, and that he left her face
    down on the bed. After a police officer noted that there was no mention of
    strangulation, the defendant amended his statement to include the fact that
    he had used his hands to get the victim to stop making noise.
    Several factual discrepancies between this account and the physical evi-
    dence discovered at the crime scene were noted at trial and, indeed, remain
    contested in the present appeal. The extent to which the defendant’s memory
    may have been impaired by drug use, both on the night of the victim’s death
    and during his interrogation, also remains disputed.
    6
    General Statutes (Rev. to 2001) § 53a-54b (5) and (6) proscribe, respec-
    tively, murder during the course of a kidnapping and murder during the
    course of sexual assault in the first degree. Because the defendant was
    charged with these capital offenses, the guilt and penalty phases of the trial
    were bifurcated pursuant to General Statutes (Rev. to 2001) § 53a-46a, as
    amended by Public Acts 2001, No. 01-151, §§ 1 and 2.
    7
    Although the defendant was originally sentenced to death on the capital
    felony counts, he was subsequently resentenced to a term of life imprison-
    ment without the possibility of release on those charges. See, e.g., State v.
    Peeler, 
    321 Conn. 375
    , 377, 
    140 A.3d 811
     (2016); State v. Santiago, 
    318 Conn. 1
    , 85–86, 
    122 A.3d 1
     (2015).

    A defendant’s right to counsel under the sixth amendment is made appli-
    cable to the states through the due process clause of the fourteenth amend-
    ment to the United States constitution. See, e.g., State v. Leconte, 
    320 Conn. 500
    , 505 n.2, 
    131 A.3d 1132
     (2016).
    9
    The record indicates that Pladsen and the defendant occupied cells
    close to one another and typically participated in recreation outside of the
    presence of other inmates.
    10
    Although the state’s brief appears to contest whether Weaver made an
    affirmative request, the trial court’s factual findings, Pladsen’s testimony,
    and the state’s own arguments at trial indicate, at the very least, that the
    topic of using a wire was broached by Weaver.
    11
    Pladsen testified that he had specifically asked Weaver about the possi-
    bility of receiving a sentence modification. Weaver testified that Pladsen
    did not expressly mention what kind of benefit he was seeking.
    12
    The record contains conflicting indications regarding the impact of
    Weaver’s statement. For example, Pladsen testified that, during this meeting,
    he had told Weaver that he ‘‘would try’’ to get more information from the
    defendant and that Weaver had not dissuaded him from doing so. Pladsen
    also testified that he continued his general ‘‘effort to obtain information
    from [the defendant]’’ after the meeting with Weaver. On another occasion,
    Pladsen testified: ‘‘I remember telling [Weaver that] I don’t mind going back
    trying to get some more information in the meantime, and I remember him
    saying, well just let me run it by the . . . state’s attorney first and let’s see
    [how] this wire pans out, and he never got back to me.’’ Finally, Pladsen
    testified that his decision to ask the defendant to write a note was a ‘‘spur
    of the moment type of thing . . . .’’ In light of these discrepancies, we are
    unable to agree with the assertion of the concurring and dissenting justice
    that the record contains ‘‘[no] evidence that Pladsen ever informed Weaver
    that he intended to obtain information from the defendant.’’ Pladsen’s testi-
    mony on this point was simply inconsistent.
    13
    In light of the messages both into and out of Northern, we respectfully
    disagree with the contention of the concurring and dissenting justice that
    ‘‘Weaver never communicated directly with Pladsen’’ in the months following
    their meeting at Northern.
    14
    Pladsen also testified that the defendant became angry later that day
    about the fact that the note had been given to the prosecution. Pladsen
    testified that he had told the defendant that the note must have been discov-
    ered in the trash and that the defendant had then asked him to claim
    authorship.
    15
    The trial court file contains an incorrect notation by the clerk indicating
    that the defendant’s motion to suppress Pladsen’s testimony was granted.
    16
    Pladsen also recounted the defendant’s reaction to the state’s discovery
    of the note and the conversation that followed. See footnote 14 of this opin-
    ion.
    17
    Following the defendant’s conviction, the trial court held an evidentiary
    hearing pursuant to State v. Floyd, 
    253 Conn. 700
    , 732, 
    756 A.2d 799
     (2000),
    in order to explore whether the state had, yet failed to disclose, an agreement
    with Pladsen at the time of trial, in violation of Brady v. Maryland, 
    373 U.S. 83
    , 
    83 S. Ct. 1194
    , 
    10 L. Ed. 2d 215
     (1963). During that hearing, the lead
    prosecutor at the defendant’s trial, Senior Assistant State’s Attorney John
    Fahey, testified that he had made no deals with Pladsen at the time of trial
    and that they had not discussed the possibility of a sentence modification.
    Fahey testified that he had promised Pladsen only that he would, ‘‘if ever
    requested, as a commissioner of the Superior Court, make known to a judge
    [the] good, bad and indifferent . . . .’’
    Two other witnesses testified at that hearing about the interactions
    between Fahey and Pladsen. The first of those witnesses, a corrections
    officer who had been assaulted by Pladsen, Karen Stratton White, testified
    that Fahey had visited her in 2015 to discuss modification of the twenty-
    five year sentence that had resulted from that assault. White testified that,
    during that discussion, she received the impression that Fahey wanted her
    ‘‘to go along with Pladsen having [a sentence modification] hearing’’ and
    that Fahey had ‘‘given his word’’ because Pladsen ‘‘had helped him with that
    other case.’’ The second witness, Pladsen’s mother, Judy Yvonne Pladsen,
    testified that she had spoken with Fahey at the time of the defendant’s trial
    and that he had ‘‘guaranteed’’ her that the court would modify her son’s
    sentence in exchange for providing testimony against the defendant. In
    rejecting the defendant’s Brady claim, however, the trial court expressly
    declined to credit the testimony of these two witnesses, stating that ‘‘[n]either
    was in a position to either confirm or deny the existence of any agreement.’’
    18
    Records of that proceeding are the proper subject of judicial notice.
    See, e.g., Shirley P. v. Norman P., 
    329 Conn. 648
    , 660, 
    189 A.3d 89
     (2018).
    19
    We note that this approach is consistent with the standard of review
    applied to the agency prong of Massiah by the majority of the federal courts
    of appeals. See, e.g., United States v. Ocean, 
    904 F.3d 25
    , 33 (1st Cir. 2018)

     (1981).
    The concurring and dissenting justice contends that this court’s observa-
    tion in State v. Alexander, supra, 
    197 Conn. 185
    , that agency is ‘‘primarily
    a question of fact’’ compels the application of the substantial evidence
    standard of review to the trial court’s ultimate conclusion on the question of
    agency. This court, however, also has characterized the deliberate elicitation
    prong in a similar manner. See State v. Swinton, supra, 
    268 Conn. 856
     (‘‘[t]he
    second issue of fact is whether [the informant] ‘deliberately elicited’ the
    defendant’s statements’’). Cases from the United States Supreme Court leave
    little room for doubt that questions of law abound in that context. In United
    States v. Henry, 
    447 U.S. 264
    , 268–69, 
    100 S. Ct. 2183
    , 
    65 L. Ed. 2d 115
    (1980), for example, the court did not even mention, much less afford
    deference to, the trial court’s ultimate conclusion on the question of deliber-
    ate elicitation.
    20
    The concurring and dissenting justice concludes that this precept is
    irrelevant to the question of agency under Massiah because that precise
    issue was not disputed in Moulton. See footnote 9 of the concurring and
    dissenting opinion. We, however, agree with those federal courts of appeals
    that read this language as a broader, guiding principle in this unique constitu-
    tional context and, accordingly, decline to cabin its import to cases examin-
    ing deliberate elicitation. See Ayers v. Hudson, 
    623 F.3d 301
    , 316 (6th Cir.
    2010); United States v. Johnson, 
    4 F.3d 904

     (1994).
    21
    In reaching this conclusion, the United States Supreme Court rejected
    an argument that the statements should be admissible because the police
    were merely fulfilling their duty to continue an investigation. Massiah v.
    United States, supra, 
    377 U.S. 206
    . Although the court recognized that such
    continuing investigations may be proper, it nonetheless concluded that the
    defendant’s own incriminating statements ‘‘could not constitutionally be
    used by the prosecution as evidence against him at his trial.’’ (Emphasis
    in original.) Id., 207.
    22
    Justice Blackmun authored a vigorous dissent asserting that the majority
    effectively had ignored the fact that the informant had been explicitly
    instructed not to ask any questions and that, by using phrases such as ‘‘ ‘must
    have known’ ’’ and ‘‘ ‘likely,’ ’’ the majority had ‘‘fundamentally restruc-
    ture[d]’’ Massiah to include even ‘‘ ‘negligent’ ’’ elicitation. United States v.
    Henry, 
    supra,
     
    447 U.S. 278
    –80 (Blackmun, J., dissenting).
    23
    Indeed, the court asked, ‘‘what use is a defendant’s right to effective
    counsel at every stage of a criminal case if, while he is held awaiting trial,
    he can be questioned in the absence of counsel until he confesses?’’ (Internal
    quotation marks omitted.) Maine v. Moulton, 
    supra,
     
    474 U.S. 171
    , quoting
    Spano v. New York, 
    360 U.S. 315
    , 326, 
    79 S. Ct. 1202
    , 
    3 L. Ed. 2d 1265
     (1959)
    (Douglas, J., concurring).
    24
    We agree with the concurring and dissenting justice that the state’s
    foreknowledge of deliberate elicitation is alone insufficient to give rise to
    an agency relationship. Simply put, such a test could result in a constitutional
    violation without any state action. See State v. Marshall, 
    882 N.W.2d 68
    , 91
    (Iowa 2016), cert. denied,         U.S.     , 
    137 S. Ct. 829
    , 
    197 L. Ed. 2d 68
    (2017). We emphasize that some action by the state is always required in
    this context; the question of whether such actions suffice to create an agency
    relationship, in turn, must be determined by examining whether, in light of
    the surrounding context, the state must have known that its own conduct
    was likely to result in an infringement of the defendant’s sixth amendment
    right to counsel. See Ayers v. Hudson, 
    623 F.3d 301
    , 311 (6th Cir. 2010)
    (‘‘[i]t is not the government’s intent or overt acts that are important; rather,
    it is the likely . . . result of the government’s acts’’ (internal quotation
    marks omitted)). In cases in which the state chooses to act, its affirmative
    obligation requires it to do so in a manner that ‘‘respect[s] and preserve[s]
    the accused’s choice to seek [the] assistance [of counsel].’’ Maine v. Moulton,
    
    supra,
     
    474 U.S. 171
    .
    25
    The concurring and dissenting justice’s reliance on Cox to support the
    proposition that Henry is irrelevant to the question of agency is, therefore,
    inapt. It is also worth noting that, although the concurring and dissenting
    justice is correct that a case from the United States Court of Appeals for
    the Fifth Circuit has declined to adopt language from Henry as governing
    the question of agency, the precise passage that court declined to engraft
    looks very similar to the test proposed by the concurring and dissenting
    justice. See Creel v. Johnson, 
    162 F.3d 385
    , 393 (5th Cir.1998) (‘‘[C]iting
    to [Henry], [the defendant] argues that we should consider whether [the
    informant] ‘was charged with the task of obtaining information from an
    accused.’ Henry involved . . . a clear case of agency, and the [c]ourt only
    considered if the agent [was] ‘charged with the task of obtaining information
    from an accused’ to determine whether the agent ‘deliberately elicited’ the
    information. [The defendant’s argument fails because] the agency inquiry
    is precedent to and distinct from determining whether an agent ‘deliberately
    elicits’ information.’’).
    26
    In State v. Swinton, supra, 
    268 Conn. 855
    , we cited a previous decision
    of this court, State v. Alexander, supra, 
    197 Conn. 185
    , for the applicable
    legal standard governing the question of agency. In Alexander, this court
    concluded that there was substantial evidence to support the trial court’s
    factual finding that an agency relationship was absent when the police drove
    a private citizen who lacked a driver’s license to meet with the defendant
    in jail on two occasions. 
    Id.,
     186–87. Although our decision in that case
    noted some level of facilitation and encouragement by the police; id.; the
    informant in that case was not incarcerated, and there was no evidence
    that he actually received anything in exchange for his cooperation. 
    Id.,
     187
    and n.4. Finally, we note that our decision in Alexander predated the United
    States Supreme Court’s pronouncement that, under Massiah, the ‘‘police
    have an affirmative obligation not to act in a manner that circumvents and
    thereby dilutes the protection afforded by the right to counsel.’’ Maine v.
    Moulton, 
    supra,
     
    474 U.S. 171
    . In light of these distinctions, our decision in
    Alexander is of limited utility in the present case.
    A Superior Court case, State v. Howell, Superior Court, judicial district
    of New Britain, Docket No. CR-05-222048-S (January 30, 2007) (Sheldon,
    J.), contains a more instructive set of facts. In that case, the defendant was
    arrested, charged with murder, and held in lieu of bond. 
    Id.
     The informant
    in that case, a fellow inmate, began interacting with the defendant in the
    prison recreation area. 
    Id.
     During a series of conversations there, the defen-
    dant remarked that his charges related to the disappearance of a prostitute
    and made certain incriminating statements. 
    Id.
     The informant subsequently
    called the police to discuss the defendant, and a detective asked, in particu-
    lar, if the defendant had said anything about the body. 
    Id.
     The informant
    responded that, although the defendant had not said anything yet, the conver-
    sations would likely ‘‘ ‘lead up to that.’ ’’ 
    Id.
     The detective affirmatively
    instructed the informant not to press the defendant for information but
    also implied that the informant should continue listening, stating: ‘‘[I]f [the
    defendant’s] offering shit you know just.’’ 
    Id.
     The informant then returned
    to the recreation area and elicited further incriminating statements from
    the defendant. 
    Id.
    The detective spoke to the informant again the following day. ‘‘This conver-
    sation began with a lengthy lecture by the [d]etective to [the informant]
    about the legal consequences of his continuing cooperation with the investi-
    gation in light of the fact that the defendant was formally charged with
    murder and had an attorney appointed to represent him. According to the
    [d]etective, [the informant] had become an agent of the [s]tate with respect
    to the police investigation of [the] death and disappearance [of the victim]
    when they first spoke on the telephone the day before. Thus, the [d]etective
    told him, he could not ask the defendant any questions on the subject of
    [the victim] . . . and he could not agree with the defendant, or even nod
    his head, if the defendant ever spoke about her.’’ (Citation omitted.) 
    Id.
     At
    trial, the state sought to admit the incriminating statements made by the
    defendant both before and after the informant’s first contact with the
    police. 
    Id.
    The trial court in that case concluded that, notwithstanding certain evi-
    dence indicating that the informant had provided information to the police
    regarding certain other cases, there was no evidence of an agency relation-
    ship before the first telephone call. 
    Id.
     The trial court also found, however,
    that an agency relationship had been established when, ‘‘upon completing
    his short phone call . . . [with] the [d]etective . . . and learning that the
    [d]etective was very interested in what the defendant might ultimately tell
    him, [the informant] returned to the recreation area to hear whatever else
    the defendant was ready to say.’’ 
    Id.
     The trial court opined that the detective’s
    admonition not to ‘‘ ‘press’ ’’ the defendant was ‘‘a far cry from the express
    and appropriate warnings’’ given the following day and that the informant’s
    actions after the first telephone call amounted to deliberate elicitation. 
    Id.
    Accordingly, the trial court in that case suppressed the evidence regarding
    the statements made by the defendant after the informant’s first contact
    with the police. 
    Id.
    27
    Because this issue relates to a question arising under the federal constitu-
    tion, case law from the Second Circuit is entitled to significant weight. See,
    e.g., Gleason v. Smolinski, 
    319 Conn. 394
    , 444 n.41, 
    125 A.3d 920
     (2015).
    28
    Although this approach has been described as a bright-line rule requiring
    government instruction as a predicate to relief under Massiah; see D. Kirsch,
    Note, ‘‘The Prosecutor Circumvents the Sixth Amendment Right to Counsel
    with a Simple ‘Wink and Nod,’ ’’ 
    69 Mo. L. Rev. 553
    , 560–61 (2004); its origins
    may be traced back to cases weighing various factors. See, e.g., United
    States v. Birbal, 
    113 F.3d 342
    , 346 (2d Cir.), cert. denied, 
    522 U.S. 976
    , 
    118 S. Ct. 433
    , 
    139 L. Ed. 2d 333
     (1997); Stano v. Butterworth, 
    51 F.3d 942
    , 977
    (11th Cir. 1995), cert. denied sub nom. Stano v. Singletary, 
    516 U.S. 1122
    ,
    
    116 S. Ct. 932
    , 
    133 L. Ed. 2d 859
     (1996); Brooks v. Kincheloe, 
    848 F.2d 940
    ,
    944–45 (9th Cir. 1988).
    29
    For largely pragmatic reasons, courts have often hesitated to articulate
    an exhaustive list of factors in this context. See, e.g., People v. Cardona,
    
    41 N.Y.2d 333
    , 335, 
    360 N.E.2d 1306
    , 
    392 N.Y.S.2d 606
     (1977) (‘‘we decline
    to subscribe to any ironclad rules as to when agency exists since the niceties
    of rule-complying form could easily mask the substance of a true agency
    relationship’’).
    30
    The concurring and dissenting justice contests this reading. See footnote
    22 of the concurring and dissenting opinion. This letter, which was marked
    as an exhibit for identification purposes, provides in relevant part: ‘‘I have
    some information that could be very useful to you and one of your cases.
    . . . I know all about Nashon and Valentino and so on. . . . You want my
    help, come [and] see me [and] we’ll talk. . . .’’ Nashon and Valentino are
    individuals related to a different criminal case then pending against the
    defendant. Indeed, as the trial court in the present case itself noted, ‘‘the
    initial letter was not about [the victim]; [Pladsen] wanted to give information
    about [the defendant’s] other crimes.’’
    31
    Although it is not entirely clear from the record whether Pladsen
    expressly indicated that he would be continuing his efforts to obtain informa-
    tion from the defendant; see footnote 12 of this opinion; that fact would
    have become apparent to the state no later than May 29, 2007, the day
    the note was given to Weaver. Pladsen’s testimony at trial indicates that,
    notwithstanding this fact, the defendant was returned to Northern later that
    same day where he made additional incriminating statements to Pladsen.
    Specifically, Pladsen testified at trial that the defendant was upset that the
    state had found the note and had asked him to claim authorship. See foot-
    notes 14 and 16 of this opinion.
    32
    We note that the record contains some evidence indicating that the
    state had expressly agreed to permit a sentence modification shortly before
    Pladsen testified in the present case. See footnote 17 of this opinion. The
    trial court, however, declined to find that evidence to be credible in ruling
    on a related postjudgment claim.
    33
    The concurring and dissenting justice concludes that the defendant’s
    incarceration ‘‘is simply not relevant to the question of whether Pladsen
    was an agent of the state.’’ We recognize that a circuit split exists on this
    particular point of law and that, as a result, the position of the concurring
    and dissenting justice is supported by relevant case law. Compare Matteo
    v. Superintendent, SCI Albion, 
    supra,
     
    171 F.3d 895
     (concluding that, ‘‘[c]er-
    tainly, the ‘special pressures’ of custody were present’’), with United States
    v. Watson, 
    894 F.2d 1345
    , 1347 (D.C. Cir. 1990) (‘‘it is of no moment that
    the incriminating conversations took place while the accused was incarcer-
    ated’’). Nonetheless, we disagree. The circumstances attendant to the defen-
    dant’s incarceration, such as the undisputed fact that he recreated alone
    with Pladsen, must be considered when evaluating the ‘‘likely . . . result
    of the government’s acts.’’ (Internal quotation marks omitted.) Ayers v.
    Hudson, 
    supra,
     
    623 F.3d 311
    . As a result, we find the reasoning of the United
    States Court of Appeals for the Third Circuit in Matteo, on balance, more
    persuasive.
    34
    Even if Pladsen’s initial private meeting with Weaver did not result in
    agency, surely, such a relationship would have been established after Pladsen
    offered, and the state affirmatively accepted, evidence specifically relating
    to the defendant’s involvement in the victim’s death. It is undisputed, how-
    ever, that Pladsen was returned to Northern after producing the note, had
    another conversation with the defendant about the present case, and was
    subsequently called by the state to testify as to that conversation. See
    footnotes 14, 16 and 31 of this opinion. Because the state has conceded
    both deliberate elicitation and harmless error in the present appeal, this
    fact alone would have been sufficient to warrant reversal of the defendant’s
    conviction.
    35
    Although the presence of such prophylactic steps does not necessarily
    preclude sixth amendment infirmity; Maine v. Moulton, 
    supra,
     
    474 U.S. 165
    ;
    United States v. Henry, 
    supra,
     
    447 U.S. 266
    –67; the state’s failure to employ
    these measures in the present case undoubtedly increased the likelihood
    of infringement of the defendant’s constitutional rights.
    36
    To conclude otherwise would allow jailhouse informants to exclude
    themselves from consideration as a state actor simply by pretending to be
    a double agent. The fact that a defendant who falls victim to such a ruse
    may himself be seeking to gain some measure of unfair advantage is irrele-
    vant. The state’s affirmative obligation to avoid infringement of the right to
    counsel precludes such gamesmanship. See Maine v. Moulton, 
    supra,
     
    474 U.S. 171
    .
    37
    We address this claim because it seeks relief in the form of a judgment
    of acquittal. See, e.g., State v. Padua, 
    273 Conn. 138
    , 178–79, 
    869 A.2d 192
     (2005).
    38
    Although the operative information charged the defendant with both
    unlawfully entering and remaining, the state’s evidence and arguments per-
    tain solely to the latter. See State v. Belton, 
    190 Conn. 496
    , 500, 
    461 A.2d 973
    (1983) (‘‘[t]o enter unlawfully contemplates an entry [that] is accomplished
    unlawfully, [whereas] to remain unlawfully contemplates an initial legal
    entry [that] becomes unlawful at the time that the actor’s right, privilege or
    license to remain is extinguished’’). Indeed, the state’s brief notes that, at
    trial, it proceeded under the theory ‘‘that, because the victim was acquainted
    with the defendant and because there were no signs of forced entry, [the
    victim] likely willingly permitted [the defendant] to enter her apartment.’’
    39
    The trial court gave the following instructions to the jury with respect
    to this element: ‘‘[T]he state must prove beyond a reasonable doubt that the
    defendant entered unlawfully or, regardless of how the defendant entered,
    he remained there unlawfully. A person enters or remains unlawfully in or
    upon premises when the premises, at the time of such entry or remaining,
    are not open to the public and when the defendant is not otherwise licensed
    or privileged to do so. It does not matter how an intruder may actually have
    entered; if he did so without license, he has entered unlawfully. Even if a
    person entered a building lawfully, that is, he had the right or had been
    given permission and the right had been terminated or the permission with-
    drawn by someone who had a right to terminate or withdraw it, you may
    find unlawfully remaining as the basis of burglary.’’
    40
    In Thomas, the state argued that the jury could have inferred an unlawful
    remaining from the fact that the defendant had ‘‘manifested an intent to
    carry out a criminal purpose’’ while inside of the convenience store. State
    v. Thomas, 
    supra,
     
    210 Conn. 207
    . In rejecting that argument, this court relied
    on a comment by the Commission to Revise the Criminal Statutes, which
    provides in relevant part: ‘‘ ‘The purpose of this definition is to make clear
    that only the kind of entry or remaining which is likely to terrorize occupants
    is prohibited by the crime of burglary. Thus, when the building is, at the
    time, open to the public, or the actor is otherwise licensed or privileged to
    be there, the element of terror is missing and the requirement is not met.’ ’’
    (Emphasis added.) 
    Id.,
     quoting Commission to Revise the Criminal Statutes,
    Penal Code Comments, Connecticut General Statutes (1969) pp. 52–53,
    reprinted in Conn. Gen. Stat. Ann. § 53a-100 (West 2012), commission com-
    ment, p. 16.
    41
    The paradigm of such an unlawful remaining occurs when a defendant
    enters a business when it is open to the public and then stays past closing.
    See State v. Allen, supra, 
    216 Conn. 384
     (‘‘A enters an office building during
    business hours—a lawful entry since the building is open to the public—
    and remains, perhaps hidden, after the building is closed, with intent to
    steal. A is guilty of burglary.’’ (Internal quotation marks omitted.)).
    42
    The defendant relies on State v. Clark, 
    48 Conn. App. 812
    , 
    713 A.2d 834
    ,
    cert. denied, 
    245 Conn. 921
    , 
    717 A.2d 238
     (1998), as an example of the
    absurd results that would occur in the absence of a bright-line rule requiring
    surreptitious conduct. In that case, the victim was sexually assaulted in her
    own kitchen by an uninvited assailant. Id., 814, 824. The defendant argues
    that, ‘‘[i]f the conduct [at issue in Clark] had occurred outdoors, [the defen-
    dant in that case] would not have been guilty of the class B felony of burglary,
    but only of the class D felony of third degree sexual assault. Clearly the
    legislature did not intend for there to be such a disparity in the sentence a
    person could receive simply because the crime was committed indoors as
    opposed to outdoors.’’
    It is, however, well established that such intrusions into the home cause
    a unique form of injury that has traditionally been punished as a separate
    and distinct offense under the law of this state. See, e.g., State v. Little, 
    194 Conn. 665
    , 675–76, 
    485 A.2d 913
     (1984). In the absence of constitutional
    infirmity, concerns regarding the penalty affixed by statute to the crime of
    burglary are appropriately addressed to the legislature. See, e.g., Washington
    v. Commissioner of Correction, 
    287 Conn. 792
    , 828, 
    950 A.2d 1220
     (2008)
    (acknowledging ‘‘the legislature’s authority to define crimes and [set] appro-
    priate penalties’’).
    43
    We note that the state also contends that any error in this regard was
    harmless and that the parties disagree on the burden of proof attendant to
    such an analysis. See State v. Arroyo, 
    284 Conn. 597
    , 614, 
    935 A.2d 975
    (2007) (declining to consider whether constitutional or nonconstitutional
    standard of harmless error review applies to improper omission of third-
    party culpability instruction). Because we address this claim as an issue
    likely to arise on remand, we need not address questions of harmless error
    in the present appeal.
    44
    Although testimony offered at trial indicated that the victim had unpro-
    tected vaginal intercourse with a particular man the night before her death,
    no evidence was introduced to demonstrate that that man was the source
    of the unknown male DNA on victim’s vaginal swab.
    45
    Ladd indicated that this saliva came from a different source than other
    male DNA found on a condom from the victim’s bedroom. In light of certain
    posttrial evidence linking the condom to another man; see footnote 44 of
    this opinion; it is reasonable to deduce that neither that man nor the defen-
    dant was the source of the male DNA discovered on the victim’s shoulder.
    We note that, although both the state and the defendant make the same
    inference in briefing various issues in the present appeal, this information
    was not available to the trial court when it instructed the jury.
    46
    With respect to this sample, Ladd testified that the victim was a major
    contributor and that the unidentified male was a minor contributor.
    47
    We note that the current revision of the model criminal jury instructions
    contains similar language. See Connecticut Criminal Jury Instructions 2.6-
    10, available at https://www.jud.ct.gov/JI/Criminal/Criminal.pdf (last visited
    August 5, 2020).
    48
    In reaching this conclusion, this court noted: ‘‘The restrictions placed
    on [third-party] culpability evidence are concerned primarily with reliability
    and, in essence, seek to ensure that a defendant does not introduce tenuous
    evidence of [third-party] culpability in an attempt to divert from himself the
    evidence of guilt. . . . Those same concerns do not exist . . . where the
    evidence the defendant [seeks] to introduce [is] reliable, physical evidence
    that had undergone the rigors of forensic analysis.’’ (Citations omitted.)
    State v. Cerreta, supra, 
    260 Conn. 262
    , citing State v. Hernandez, 
    224 Conn. 196
    , 202, 
    618 A.2d 494
     (1992) (evidence of threat by third party), and State
    v. Echols, 
    203 Conn. 385
    , 392–94, 
    524 A.2d 1143
     (1987) (evidence that third-
    party lookalike committed similar crime in same vicinity).
    49
    This evidence stood in contrast to an unidentified print lifted from a
    gasoline filled soda bottle that had been used in the commission of the
    underlying crime that, we noted, had been properly admitted during the
    course of the underlying trial. State v. West, 
    supra,
     
    274 Conn. 616
    , 627 n.29.
    50
    We note that the trial court ‘‘is in the best position to view the evidence
    in the context of the entire case and has wide discretion in making its
    evidentiary rulings.’’ State v. Schovanec, supra, 
    326 Conn. 320
    ; see also State
    v. Walsh, 
    67 Conn. App. 776
    , 790, 
    789 A.2d 1031
    , cert. denied, 
    260 Conn. 906
    , 
    795 A.2d 546
     (2002). Like the decision of whether to give a third-party
    culpability instruction, a trial court’s decision as to the admissibility of
    ‘‘[third-party] inculpatory evidence will be reversed on appeal only if the
    court has abused its discretion or an injustice appears to have been done.’’
    (Internal quotation marks omitted.) State v. West, 
    supra,
     
    274 Conn. 626
    .
    51
    For example, a trial court that exercises its discretion to admit forensic
    evidence demonstrating the presence of a third party at a crime scene
    nonetheless may act within its discretion by declining to give a third-party
    culpability instruction in the event the evidence actually admitted at trial
    falls short of proving a direct connection. Put differently, the fact that the
    trial court’s predicate evidentiary rulings may have benefited the defendant
    does not compel the conclusion that its ultimate decision to withhold an
    instruction was error. Cf. State v. Schovanec, supra, 
    326 Conn. 316
    –17, 323.
    52
    We emphasize that the question of whether the evidence actually admit-
    ted in any new trial will reasonably support a third-party culpability instruc-
    tion must be vested, in the first instance, to the sound discretion of the trial
    court. See, e.g., State v. Jackson, 
    supra,
     
    304 Conn. 424
    .
