    STATE v. ASHBY—CONCURRENCE AND DISSENT
    MULLINS, J., concurring in part and dissenting in
    part. I respectfully disagree with part I of the majority
    opinion1 because, in my view, there is ample support
    in the record for the trial court’s factual finding that
    Kenneth Pladsen, Jr., was not acting as an agent of the
    state when he elicited certain incriminating statements
    from the defendant, Lazale Ashby. Accordingly, I would
    conclude that the trial court correctly denied the defen-
    dant’s motion to suppress those statements because the
    state did not obtain them in violation of the defendant’s
    sixth amendment right to counsel under Massiah v.
    United States, 
    377 U.S. 201
    , 
    84 S. Ct. 1199
    , 
    12 L. Ed. 2d 246
     (1964). I would therefore affirm the defendant’s
    convictions stemming from the December 1, 2002 mur-
    der of the victim.2
    Consistent with the majority of jurisdictions across
    the country, this court has recognized that an informant
    who obtains incriminating information from a defen-
    dant is not an agent of the state for purposes of Massiah
    unless the state had expressly or implicitly directed the
    informant to obtain information, or offered the infor-
    mant some type of benefit in exchange for information.
    See, e.g., State v. Swinton, 
    268 Conn. 781
    , 858, 
    847 A.2d 921
     (2004) (jailhouse informant was not state agent when
    he obtained information without having been directed
    to do so or offered reward). Pladsen’s testimony at
    the suppression hearing, which this court is bound to
    accept on appeal because the trial court explicitly cred-
    ited it, establishes that these requirements are not pres-
    ent in this case.
    Pladsen testified that, during his single meeting with
    Detective Andrew Weaver of the Hartford Police Depart-
    ment on January 5, 2007, (1) Weaver never instructed
    him to obtain information from or do ‘‘anything relative
    to’’ the defendant, (2) he and Weaver made no ‘‘agree-
    ment of any sort,’’ (3) it was not ‘‘implied’’ to him that
    he should obtain information, and (4) Weaver made
    ‘‘very clear’’ he was not offering any benefits or deals
    and, in fact, lacked the authority to do so. Pladsen fur-
    ther testified that his subsequent decision, made several
    months later, to obtain the incriminating statements
    from the defendant was one that he made ‘‘on [his]
    own,’’ rather than in response to any directive from
    Weaver, and that he did so on the ‘‘spur of the moment’’
    when ‘‘the opportunity presented itself . . . .’’ This tes-
    timony provides ample—if not overwhelming—support
    for the trial court’s finding that Pladsen was not a state
    agent.
    This case also lacks any of the other circumstances
    typically characteristic of an agency relationship. The
    state had no preexisting arrangement with Pladsen or
    any plan to use his services. Pladsen had no history of
    serving as an informant; indeed, Weaver was completely
    unaware of Pladsen until he reached out to Weaver
    and requested a meeting. Nor did the police have any
    involvement in or control over Pladsen’s activities. They
    were uninvolved in the placement of Pladsen in the cell
    next to the defendant, and Weaver’s single meeting with
    Pladsen occurred several months before Pladsen
    obtained the incriminating information from the defen-
    dant. During the intervening months, Weaver never
    communicated directly with Pladsen and did not direct
    or control his interactions with the defendant. Most
    important, no state official ever asked, directed or sug-
    gested that Pladsen obtain any information from the
    defendant. In light of this evidence, I simply do not see
    how the trial court’s finding that Pladsen was acting
    on his own initiative, rather than as an agent of the
    state, is not supported by substantial evidence.
    The majority does not dispute most of these points.
    Instead, it approaches the agency question from an
    entirely different road—one that, in my view, cannot
    be reconciled with this court’s prior cases. In so doing,
    the majority implicitly overrules or abrogates numerous
    of this court’s prior decisions addressing agency ques-
    tions in the context of sixth amendment and other con-
    stitutional claims. For instance, this court has long rec-
    ognized that a trial court’s agency determination is a
    factual question that must be upheld on appeal as long
    as it is supported by substantial evidence. Today, how-
    ever, the majority reverses that line of cases and con-
    cludes that it is a mixed question of law of fact subject
    to plenary review.
    Furthermore, and far more significant, the majority
    abandons this court’s long settled test for determining
    whether an informant acted as a state agent—a test
    requiring some showing that the police had expressly
    or impliedly asked for information or offered an induce-
    ment for obtaining it—in favor of a new standard under
    which the dispositive question is whether the police
    ‘‘knew or should have known’’ that the conversation
    with the informant ‘‘was likely to end in further deliber-
    ate elicitation.’’ I respectfully disagree with this new
    standard. In my view, it is based on a misreading of
    the United States Supreme Court’s decision in United
    States v. Henry, 
    447 U.S. 264
    , 
    100 S. Ct. 2183
    , 
    65 L. Ed. 2d 115
     (1980), a case widely regarded as largely
    irrelevant to the agency prong of Massiah, and is at odds
    with precedent from this court and other jurisdictions.
    Finally, even accepting the majority’s framing of the
    correct standard, I disagree that Weaver ‘‘knew or
    should have known’’ that his meeting with Pladsen, as
    opposed to Pladsen’s own preexisting desire to curry
    favor with the police, would have prompted Pladsen to
    attempt to elicit additional incriminating information
    from the defendant. In my view, the majority’s analysis
    reads more into the testimony at the suppression hear-
    ing than is appropriate, relies on factors that have lim-
    ited or no relevance to agency, and is based primarily on
    the majority’s own assumptions about what motivated
    Pladsen and how he interpreted his meeting with
    Weaver, some of which are undermined by Pladsen’s
    own testimony.
    To be sure, the majority raises some legitimate con-
    cerns about the way in which Weaver handled his inter-
    actions with Pladsen. In particular, Weaver asked Plad-
    sen if he would be willing to wear a wire sometime in
    the future in order to record his conversations with the
    defendant. Although Weaver never pursued the wire
    and made clear to Pladsen that he was not authorizing
    such a tactic and, in fact, lacked authority to proceed
    any further, such a statement, when considered in isola-
    tion, could arguably have suggested to Pladsen that
    additional incriminating information was desired. Ulti-
    mately, however, the significance the majority accords
    this statement is directly contradicted by Pladsen’s own
    testimony—which was credited by the trial court—that
    he had not been offered anything or directed to do
    anything, and that he obtained the information from
    the defendant, not as a result of anything Weaver had
    said to him, but on his own initiative.
    I
    APPLICABLE LEGAL PRINCIPLES
    I begin with the general principles governing the
    defendant’s claim. Under Massiah v. United States,
    supra, 
    377 U.S. 201
    , a defendant’s sixth amendment
    right to counsel is violated if a state agent deliberately
    elicits incriminating information from the defendant
    after formal charges have been brought and outside the
    presence of the defendant’s counsel. 
    Id.,
     205–206. ‘‘[T]he
    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.’’
    Maine v. Moulton, 
    474 U.S. 159
    , 171, 
    106 S. Ct. 477
    , 
    88 L. Ed. 2d 481
     (1985).
    To prevail on a Massiah claim, the defendant must
    demonstrate that the informant both (1) was acting as
    an agent of the state, and (2) ‘‘deliberately elicited’’ the
    incriminating statements from him. (Internal quotation
    marks omitted.) State v. Swinton, supra, 
    268 Conn. 855
    –56. Under this dual pronged analysis, ‘‘the agency
    inquiry is precedent to and distinct from determining
    whether [the] agent ‘deliberately elicits’ information.’’
    (Emphasis added.) Creel v. Johnson, 
    162 F.3d 385
    , 393
    (5th Cir. 1998), cert. denied, 
    526 U.S. 1148
    , 
    119 S. Ct. 2027
    , 
    143 L. Ed. 2d 1038
     (1999); see, e.g., State v. Swin-
    ton, 
    supra,
     855–56 (analyzing separately questions of
    agency and deliberate elicitation).
    In the present case, the state does not contest that
    Pladsen deliberately elicited information from the
    defendant. The sole issue is whether Pladsen was acting
    as an agent of the state when he did so. As I will explain;
    see part II of this opinion; there is ample support in
    the record for the trial court’s finding that he was not.
    A
    Standard of Review
    Before addressing the substantive agency question,
    however, I must note my disagreement with the majori-
    ty’s treatment of the trial court’s finding that Pladsen
    was not acting as an agent of the state as a question
    of law that is subject to plenary review. I would adhere
    to this court’s long line of decisions, all of which recog-
    nize that such determinations are factual findings that
    are entitled to deference on appeal.
    It is well settled in Connecticut that ‘‘[t]he issue of
    agency, even in a constitutional context, is primarily a
    question of fact . . . .’’ (Citations omitted.) State v.
    Alexander, 
    197 Conn. 180
    , 185, 
    496 A.2d 486
     (1985); see
    also State v. Swinton, supra, 
    268 Conn. 855
     (agency is
    ‘‘issue of fact’’). Ordinarily, this court cannot overturn
    factual findings unless they are clearly erroneous.
    ‘‘When, however, [a question of fact is essential to the
    resolution of a constitutional claim and] the credibility
    of the witnesses is not the primary issue, our customary
    deference to the trial court is tempered by the necessity
    for a scrupulous examination of the record to ascertain
    whether such a factual finding is supported by substan-
    tial evidence.’’ (Internal quotation marks omitted.) State
    v. Alexander, supra, 185.
    This ‘‘substantial evidence’’ standard of review, how-
    ever, although less deferential than the clearly errone-
    ous standard, does not amount to plenary review. See
    State v. Pinder, 
    250 Conn. 385
    , 421, 
    736 A.2d 857
     (1999)
    (‘‘the ‘substantial evidence’ language’’ is ‘‘inconsistent
    with the plenary review that we in fact conduct’’ when
    reviewing legal question of whether confession is volun-
    tary); see also State v. Johnson, 
    253 Conn. 1
    , 124–26, 
    751 A.2d 298
     (2000) (Schaller, J., dissenting) (scrupulously
    reviewing record for substantial evidence is more defer-
    ential than plenary review). In other words, we cannot
    disregard the trial court’s finding and make our own
    independent determination as to whether Pladsen was
    an agent of the state. Rather, the trial court’s conclusion
    is ‘‘entitled to deference so long as [it is] supported by
    substantial evidence . . . .’’ State v. Whitaker, 
    215 Conn. 739
    , 754, 
    578 A.2d 1031
     (1990). That is why this
    court has upheld findings that no agency relationship
    existed on appeal, even when the record revealed some
    evidence tending to show such a relationship. See State
    v. Alexander, supra, 
    197 Conn. 187
     (trial court’s finding
    that private citizen was not state agent was supported
    by substantial evidence despite extensive police
    involvement and encouragement because ‘‘[b]alanced
    against these factors’’ was evidence that ‘‘support[ed]
    the trial court’s conclusion’’); see also State v. Lasaga,
    
    269 Conn. 454
    , 466–67, 
    848 A.2d 1149
     (2004) (upholding
    finding of no agency relationship despite ‘‘conflicting
    testimony regarding whether the police had asked [the
    private citizen] to continue to provide them with more
    information’’).
    The majority acknowledges this ‘‘substantial evi-
    dence’’ limitation on our scope of review in passing but
    then proceeds to treat agency as a mixed question of
    law and fact, deferring only to the trial court’s subsid-
    iary factual findings, while reviewing de novo the
    court’s ultimate determination of whether those facts
    created an agency relationship.3
    This court, however, has uniformly recognized that
    the ultimate determination of agency is itself a factual
    finding; see State v. Swinton, supra, 
    268 Conn. 855
    ;
    State v. Alexander, supra, 
    197 Conn. 185
    ; that must be
    upheld on appeal as long as there is substantial evidence
    to support it. See State v. Betts, 
    286 Conn. 88
    , 101, 
    942 A.2d 364
     (2008) (‘‘there was substantial evidence to
    support the trial court’s conclusion that [the private
    actor] was not an agent of the police’’); State v. Lasaga,
    supra, 
    269 Conn. 466
     (‘‘our examination of the record
    reveals that there was substantial evidence for the trial
    court’s conclusion’’ that private actor was not state
    agent); State v. Alexander, supra, 185 (‘‘there was sub-
    stantial evidence for the trial court’s conclusion that
    [the private actor] was not acting as an agent of the
    state’’); see also State v. Betts, 
    supra,
     95 n.14 (emphasiz-
    ing that agency issues are correctly reviewed under
    substantial evidence rather than plenary standard).
    In footnote 19 of its opinion, the majority expressly
    disavows the substantial evidence method of review
    applied in these prior decisions—thereby rendering the
    conclusions reached in those decisions of virtually no
    precedential value—in favor of the de novo standard
    employed by many of the federal courts of appeals.4
    Although I welcome any tacit concession from the
    majority that the trial court’s determination that Plad-
    sen was not a state agent is supported by substantial
    evidence and would have to be upheld under that stan-
    dard, I see no compelling reason to take the drastic
    step of overturning this body of case law, particularly
    when neither party in the present case has explicitly
    asked us to do so, and when federal courts of appeals
    are split on the issue.5 See State v. McCleese, 
    333 Conn. 378
    , 412–13, 
    215 A.3d 1154
     (2019) (‘‘when no party has
    asked us to overrule precedent, we are particularly
    reluctant to address . . . much less disturb’’ such prec-
    edent).
    The majority’s use of a plenary standard of review
    colors its analysis in substantive ways. Rather than limit
    itself to the question of whether there is adequate sup-
    port in the record for the trial court’s finding, the major-
    ity bases its analysis largely on its own assumptions
    about Pladsen’s subjective motivations and how he
    likely interpreted his conversation with Weaver. For
    instance, the majority posits that Weaver’s meeting with
    Pladsen must have ‘‘indicate[d]’’ to Pladsen that the
    state wanted incriminating information about the defen-
    dant; that Pladsen must have ‘‘readily infer[red]’’ that
    the state only wanted verifiable evidence about this
    particular case, ‘‘such as a recording or writing’’; that
    their conversation suggested to Pladsen that the state
    would be willing to provide him with a benefit in
    exchange for information; and that the state’s decision
    not to object to Pladsen’s subsequent request for modifi-
    cation of his sentence ‘‘provided something objectively
    valuable [to Pladsen] in exchange for [his] coopera-
    tion.’’
    Pladsen, however, who was questioned extensively
    at the suppression hearing, never testified that he inter-
    preted his meeting with Weaver in the manner that the
    majority suggests. Nor did the trial court make any
    such factual findings. I, of course, acknowledge that
    our scrupulous review of the record ‘‘must take account
    of any undisputed evidence that does not support the
    trial court’s ruling . . . but that the trial court did not
    expressly discredit.’’ State v. Edmonds, 
    323 Conn. 34
    ,
    39, 
    145 A.2d 861
     (2016); see also State v. DeMarco, 
    311 Conn. 510
    , 520 and n.4, 
    88 A.3d 491
     (2014). This basic
    proposition does not, however, permit this court to
    draw its own factual inferences from the evidence and
    then use those inferred facts as the basis for reversing
    the trial court’s ultimate finding that Pladsen was not
    a state agent. The limited question before us is whether
    the trial court’s finding is supported by substantial evi-
    dence, not whether we, ourselves, would draw a differ-
    ent conclusion on the basis of that evidence.
    Indeed, a number of the majority’s assumptions about
    how Pladsen interpreted his meeting with Weaver are
    directly contradicted by Pladsen’s own testimony,
    which the trial court expressly credited.6 For instance,
    contrary to the majority’s supposition that the meeting
    confirmed in Pladsen’s mind that the state would treat
    him favorably in exchange for information about the
    defendant, Pladsen testified that Weaver made it ‘‘very
    clear’’ that he could offer no deals or benefits, and flatly
    denied that he and Weaver had reached any mutual
    understanding by ‘‘implication,’’ that anything had been
    ‘‘implied’’ to him, or that there was any ‘‘meeting of the
    minds . . . .’’ Further, any suggestion by the majority
    that Pladsen’s decision to elicit information from the
    defendant was spurred on by Weaver is hard to square
    with Pladsen’s testimony that, when he left the meeting,
    he did not necessarily intend to seek information from
    the defendant, and that his subsequent decision to do
    so (made several months later) was one that he made
    ‘‘on [his] own.’’
    Accordingly, I would adhere to this court’s prior deci-
    sions and review the trial court’s determination of
    agency only for substantial evidence. The majority’s
    resort to plenary review, in addition to its overruling
    of these prior cases, results in an analysis that is unteth-
    ered to the trial court’s factual findings and is based
    entirely on its own independent interpretation of the
    evidence. Such an approach invades the province of
    the trial court as principal fact finder. See, e.g., State v.
    Johnson, 
    supra,
     
    253 Conn. 124
     (Schaller, J., dissenting)
    (application of de novo rather than substantial evidence
    review to factual determination ‘‘invad[es] the province
    of the jury’’).
    B
    Legal Standard for Determining Agency
    I also disagree with the legal standard the majority
    applies for determining whether Pladsen was a state
    agent. Abandoning the multifactor test recognized in
    this court’s prior agency cases, the majority relies on
    United States v. Henry, 
    supra,
     
    447 U.S. 264
    , to conclude
    that Pladsen was a state agent because Weaver ‘‘knew
    or should have known’’ that the conversation with the
    informant ‘‘was likely to end in further deliberate elicita-
    tion.’’ I disagree with the majority’s adoption of this
    new standard. As case law from this court and other
    jurisdictions has recognized, agency depends not on
    what the officer knew or should have known, but on
    whether the officer’s conduct amounted to an express
    or implied request for information or offer of a benefit
    in exchange for information.
    As an initial matter, Henry is of limited import in the
    present case because it was decided in the context of
    the deliberate elicitation prong of Massiah, rather than
    the agency prong. Indeed, the agency relationship
    between the inmate and the government was clear and
    virtually undisputed in Henry. The inmate had been
    serving the government as a paid informant for more
    than one year pursuant to a contingency fee arrange-
    ment under which the government would compensate
    him only when he provided favorable information.7
    United States v. Henry, 
    supra,
     
    447 U.S. 270
    . Govern-
    ment officers directed the inmate to approach the defen-
    dant, who was housed in the same jail awaiting trial,
    and instructed him ‘‘not to initiate’’ any conversations
    with the defendant but to ‘‘be alert to any statements’’
    that the defendant might make about the crimes for
    which he was charged. Id., 266. Despite these instruc-
    tions, the inmate engaged the defendant in conversa-
    tions and extracted incriminating statements from him,
    which later were admitted against him at trial. Id., 266–
    67. The government paid the inmate for this assistance.
    Id., 266.
    The United States Supreme Court framed the issue
    as being ‘‘whether under the facts of this case a [g]overn-
    ment agent ‘deliberately elicited’ incriminating state-
    ments from [the defendant] within the meaning of Mas-
    siah.’’ Id., 270. In answering this question in the affirmative,
    the court relied on three factors: ‘‘First, [the informant]
    was acting under instructions as a paid informant for
    the [g]overnment; second, [the informant] was ostensi-
    bly no more than a fellow inmate of [the defendant];
    and third, [the defendant] was in custody and under
    indictment at the time he was engaged in conversation
    by [the informant].’’ Id. In response to the govern-
    ment’s argument that the informant had been specifi-
    cally instructed not to affirmatively seek information,
    the court made the following observation, which the
    majority seizes on in the present case: ‘‘Even if the
    [officer’s] statement that he did not intend that [the
    informant] would take affirmative steps to secure
    incriminating information is accepted, he must have
    known that such propinquity likely would lead to that
    result.’’ (Emphasis added.) Id., 271.
    I do not believe that Henry stands for the proposition
    that agency depends on whether the officer who meets
    with the informant ‘‘must have known’’ that their con-
    versation would cause the informant to later attempt
    to seek additional information from the defendant. See
    State v. Willis, 
    496 S.W.3d 653
    , 709 (Tenn. 2016)
    (Rejecting argument that ‘‘the defendant may establish
    that an informant was a government agent by a mere
    showing that the [s]tate ‘must have known that its agent
    was likely to obtain incriminating statements’ from the
    defendant without counsel present . . . . We must
    reject any test that would deem an informant to be a
    government agent simply because the government was
    aware or ‘must have known’ that the informant would
    likely receive incriminating statements from the defen-
    dant.’’), cert. denied,    U.S.    , 
    137 S. Ct. 1224
    , 
    197 L. Ed. 2d 466
     (2017).
    Indeed, as courts have consistently recognized,
    Henry says little about agency at all. The United States
    Supreme Court ‘‘essentially assumed the existence of
    agency’’ in Henry because the informant’s contingency

    ments had been deliberately elicited rather than the
    question of whether the informants were acting as gov-
    ernment agents’’) (overruled in part on other grounds

    ,
    1347–48 (D.C. Cir. 1990) (fact that informant was in
    custody, which was relied on as relevant factor in
    Henry, is irrelevant to agency); State v. Swinton, supra,
    
    268 Conn. 858
     (noting that Henry did not discuss
    agency); State v. Alexander, supra, 
    197 Conn. 184
    (‘‘Henry did not specifically address the question of
    agency’’). Thus, the majority’s reliance on Henry for the
    governing standard on agency questions in misplaced.
    Moreover, this court has never interpreted Henry as
    suggesting that an agency relationship depends on what
    the officer who met with the informant knew or should
    have known. Instead, this court explained in Alexander:
    ‘‘In Henry, the [c]ourt considered it critical that the
    informant, previously in the government’s paid employ
    in similar missions, was specifically contacted by the
    government and given his charge respecting the pro-
    curement of possibly incriminating information from
    [the defendant]. Also important to the Henry [c]ourt
    was the fact that the informant’s mission was on a
    [contingent fee] basis . . . thereby demonstrating a
    formal prearrangement . . . between [the] state and
    [the] informant . . . . From these circumstances the
    [c]ourt in Henry was able to characterize the informant
    as a [g]overnment agent expressly commissioned to
    secure evidence . . . from the accused.’’ (Citations
    omitted; internal quotation marks omitted.) State v.
    Alexander, supra, 
    197 Conn. 184
    , quoting Thomas v.
    Cox, supra, 
    708 F.2d 135
    ; see also State v. Swinton,
    supra, 
    268 Conn. 858
     (characterizing Henry as case in
    which ‘‘government officials . . . identified [a] specific
    [prisoner] from whom they wanted information and
    found [an informant] to retrieve that information’’).8
    Thus, it was the officers’ specific instructions to the
    informant and their preexisting fee arrangement with
    him—and not the officers’ constructive knowledge—
    that drove the United States Supreme Court’s agency
    analysis in Henry.
    Consistent with this interpretation of Henry, this
    court, in Alexander, established the following standard
    for addressing agency questions: ‘‘The existence of an
    agency relationship . . . turns [on] 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-moti-
    vated . . . whether the police have asked the infor-
    mant to obtain incriminating evidence and placed him
    in a position to receive it . . . and whether the informa-
    tion is secured as part of a government initiated, [preex-
    isting plan].’’ (Citations omitted.) State v. Alexander,
    supra, 
    197 Conn. 184
    –85. Since Alexander, this court
    has consistently relied on these factors as ‘‘the primary
    factors to be considered in determining when an other-
    wise private citizen has become an agent of the govern-
    ment.’’ State v. Gordon, 
    197 Conn. 413
    , 421, 
    504 A.2d 1020
     (1985); see 
    id.
     (relying on factors in context of
    sixth amendment right to counsel); see also State v.
    Betts, 
    supra,
     
    286 Conn. 89
    , 96 (fourth amendment search
    and seizure); State v. Lasaga, supra, 
    269 Conn. 463
    –64
    (fourth amendment search and seizure); State v. Swin-
    ton, 
    supra,
     
    268 Conn. 855
    –59 (sixth amendment right
    to counsel).
    As the Alexander factors indicate on their face, an
    agency analysis turns not on the officer’s constructive
    knowledge about the informant’s likely future conduct,
    but on whether the officer said or did anything that
    amounted to an express or implied request for informa-
    tion or offer of a reward for information. A review of
    this court’s sixth amendment cases demonstrates that,
    in the absence of these minimal requirements, there is
    no agency relationship.
    Alexander, this court’s leading agency decision in the
    sixth amendment context, is perhaps the most compel-
    ling example. In that case, the defendant was incarcer-
    ated while awaiting trial on arson charges. State v. Alex-
    ander, supra, 
    197 Conn. 181
    , 188. At the time, the victim,
    who had been implicated as an accomplice in that arson,
    was missing. Id., 181. James Papagolas, who had
    befriended both the defendant and the victim, encoun-
    tered two police officers by chance and informed them
    that he was planning to visit the defendant in jail. Id.,
    182, 186. Papagolas ‘‘agreed to contact the police if he
    heard anything about the victim.’’ Id., 186. During a
    subsequent visit, the defendant admitted to Papagolas
    that he had killed the victim. Id. Papagolas immediately
    informed the officers of the defendant’s confession. Id.
    After learning of the defendant’s admission, the offi-
    cers drove Papagolas to the jail on three subsequent
    occasions for additional visits with the defendant. Id.
    Each time, the officers waited for Papagolas outside
    the jail, and, on the ride home, Papagolas told them
    what he had learned from the defendant. Id. During
    the final visit, the defendant told Papagolas where the
    victim’s body was located. Id., 186–87. At his trial for
    the murder, the defendant moved to suppress the
    incriminating statements he made to Papagolas on the
    ground that they were elicited from him without his
    counsel present, in violation of Massiah. Id., 182–83.
    The trial court found that Papagolas was not acting as
    a state agent and admitted the statements. Id., 183.
    This court affirmed, concluding that there was ‘‘sub-
    stantial evidence’’ to support the trial court’s finding
    because, ‘‘[a]lthough the police may have supported
    and even encouraged Papagolas’ efforts to obtain infor-
    mation from the defendant, their involvement was not
    so extensive as to create an agency relationship.’’ Id.,
    185–86. This court acknowledged that ‘‘[t]he transporta-
    tion service provided by the police is the strongest
    evidence of a possible agency relationship’’ and that
    there was evidence that, ‘‘by the time of his final visit,
    Papagolas was motivated, at least in part, by a feeling
    of responsibility toward the police.’’ Id., 187. ‘‘There was
    also conflicting testimony about whether [the officers]
    ever asked Papagolas to go to the jail to get information
    as opposed to simply supporting his own decision to
    go there.’’ Id. Nonetheless, this court concluded that,
    ‘‘[i]n sum,’’ the record provided adequate support for the
    trial court’s finding because ‘‘[b]alanced against these
    factors, which tend to show police involvement, is the
    fact that the police neither initiated contact with Papa-
    golas nor directed his activities. Papagolas had no previ-
    ous affiliation with the police and was neither rewarded
    monetarily nor promised any favors in return for his
    cooperation.’’ Id.
    Given the officers’ extensive involvement with Papa-
    golas—they drove him to visit the defendant multiple
    times after learning he had elicited a confession from
    the defendant—they surely ‘‘knew or should have
    known’’ that their conduct would lead to Papagolas’
    attempt to elicit additional incriminating statements
    from the defendant. See State v. Betts, 
    supra,
     
    286 Conn. 98
     (‘‘[Alexander] illustrates how extensive police con-
    tact with a private citizen may be without creating an
    agency relationship’’). Nonetheless, this court upheld
    the trial court’s finding that Papagolas was not an agent
    of the state, demonstrating that agency does not depend
    on what the officers must have known but, rather, on
    whether they ‘‘directed [the informant’s] activities’’ or
    promised something ‘‘in return for [the informant’s]
    cooperation.’’9 State v. Alexander, supra, 
    197 Conn. 187
    .
    Indeed, as I will explain; see part II of this opinion;
    Alexander cannot be reconciled with the majority’s con-
    clusion in the present case.10
    This court also emphasized these baseline agency
    requirements in the jailhouse informant context in State
    v. Swinton, supra, 
    268 Conn. 781
    . In Swinton, an inmate
    assisted the police in multiple cases unrelated to the
    defendant. 
    Id.,
     852–53. While still serving as an infor-
    mant in one of those unrelated cases, the inmate had
    numerous conversations with the defendant, during
    which the defendant made incriminating statements.
    
    Id., 853
    . This court held that the inmate was not an
    agent of the state when he obtained these statements
    because the police had given him ‘‘no instructions what-
    soever . . . that he was to gather information about
    crimes . . . or that he would be rewarded if he pro-
    vided any such information.’’ (Internal quotation marks
    omitted.) 
    Id., 858
    . This court emphasized that, in the
    absence of any such directive or promise, ‘‘a trial court
    [correctly] may determine that an informant was not
    so much a government agent . . . as he was an entre-
    preneur who hoped to sell information to the govern-
    ment.’’ (Internal quotation marks omitted.) Id.; see also
    State v. Lasaga, supra, 
    269 Conn. 466
     (private citizen
    was not state agent when police promised him no favors
    in return for cooperation); State v. Gordon, supra, 
    197 Conn. 422
    –23 (private citizen was not state agent when
    there was no evidence to support claim of ‘‘implied
    exchange of promises [to] obtain information for the
    state’’ in exchange for benefit).
    Consistent with Alexander and Swinton, courts in
    other jurisdictions similarly recognize that some type
    of state directive or promise is an essential prerequisite
    to an agency relationship under Massiah. ‘‘Although
    there are some differences in the approaches of the
    various jurisdictions, they are unified by at least one
    common principle: to qualify as a government agent,
    the informant must at least have some sort of agreement
    with, or act under instructions from, a government offi-
    cial.’’ Manns v. State, 
    122 S.W.3d 171
    , 183–84 (Tex.
    Crim. App. 2003); see, e.g., United States v. Ocean, 
    904 F.3d 25
    , 33 (1st Cir. 2018) (‘‘[a] successful Massiah
    objection requires a defendant to show, at a bare mini-
    mum, that the person with whom he conversed had

    uted to the [s]tate if no promises are made for that

    of that individual’’ (emphasis omitted; internal quota-
    tion marks omitted)).11
    In adopting this new ‘‘must have known’’ standard
    from Henry, under which there need not be any show-
    ing that the officer expressly or tacitly asked for infor-
    mation or offered a benefit in exchange for it, the major-
    ity impliedly overrules all of this court’s aforementioned
    agency decisions, which had explicitly recognized these
    elements as the minimum requirements needed to
    establish an agency relationship under Massiah. In my
    view, this prior approach, which is fully consistent with
    decisions from other jurisdictions, ‘‘gives better guid-
    ance to law enforcement authorities’’ about ‘‘what they
    can or cannot do’’; United States v. LaBare, 
    191 F.3d 60
    , 65 (1st Cir. 1999); than the amorphous ‘‘must have
    known’’ test that the majority announces today.
    I would therefore adhere to the agency standard
    employed in this court’s prior decisions. With that stan-
    dard in mind, I turn to an analysis of the evidence in
    the present case.
    II
    ANALYSIS
    In my view, and in light of the authorities discussed
    in part I of this opinion, there is substantial evidence
    in the record to support the trial court’s finding that
    Pladsen was not acting as a state agent when he elicited
    the incriminating information from the defendant.
    Indeed, Pladsen’s testimony at the suppression hearing,
    which this court is bound to accept on appeal because
    the trial court credited it; see, e.g., State v. DeMarco,
    supra, 
    311 Conn. 519
    –20; is itself sufficient to support
    the trial court’s finding because it directly undermines
    the essential requirements of agency. Pladsen testified
    that he and Weaver entered into no ‘‘agreement of any
    sort,’’ including by ‘‘implication.’’12 Pladsen further testi-
    fied that Weaver did not offer him any benefits but had
    in fact made ‘‘very clear’’ that he ‘‘wasn’t allowed to
    make any deals’’ or ‘‘do anything’’ without authorization
    from the Office of the State’s Attorney.13 See, e.g.,
    United States v. Johnson, 
    4 F.3d 904
    , 912 (10th Cir.
    1993) (there was no agency relationship when govern-
    ment indicated it was offering no benefit in exchange
    for information), cert. denied,

     (1994), and cert. denied sub
    nom. Carroll v. United States,

    ,

     (1994), and cert. denied sub
    nom. Nottingham v. United States, 
    510 U.S. 1123
    , 
    114 S. Ct. 1081
    , 
    127 L. Ed. 2d 398
     (1994); Commonwealth
    v. Foxworth, supra, 
    473 Mass. 158
     (jailhouse informant
    was not state agent when police told him they lacked
    authority to enter into any agreements with him and
    that no promises were being made).
    Furthermore, Pladsen testified that Weaver did not
    direct him to take any action relative to the defendant
    and that he decided to elicit the incriminating informa-
    tion on his own accord:
    ‘‘[The Prosecutor]: With respect to any of those
    actions . . . up to the point when [the defendant] gave
    you the [note] or even [when] subsequently talking to
    [the defendant] again this week, did Detective Weaver
    ever direct you to do anything relative to [the defen-
    dant]?
    ‘‘[The Prosecutor]: You did this on your own?
    ‘‘[Pladsen]: Yes.
    ***
    ‘‘[Defense Counsel]: Did you talk to Detective Weaver
    about different ways to obtain information from [the
    defendant]?
    ‘‘[Pladsen]: No. No, not at all.
    ‘‘[Defense Counsel]: Did Detective Weaver ever speak
    to you about getting information from [the defendant]
    by asking him questions about his cases?
    ‘‘[Pladsen]: No. He never told me to ask [the defen-
    dant] questions about his cases.’’ (Emphasis added.)
    In fact, Pladsen testified that, when he asked Weaver
    if he should obtain information from the defendant,
    Weaver told him to ‘‘just wait’’ until he could speak to
    the Office of the State’s Attorney to determine how, or
    if, to proceed. Despite this admonishment, and despite
    not having communicated directly any further with
    Weaver for several months, Pladsen took it upon him-
    self to convince the defendant to write a note containing
    details about the crime under the guise that Pladsen
    would use it to discredit Weaver as a trial witness.
    Regarding his decision to seek the note, Pladsen testi-
    fied:
    ‘‘[Defense Counsel]: And was it your testimony that
    it was your idea to try to get [the defendant] to write
    something down?
    ‘‘[Pladsen]: Yes. It was. It was kind of a spur of the
    moment type of thing. It wasn’t like I planned on like
    doing it, but the opportunity presented itself, so I took
    advantage of it if you want to say.’’
    Pladsen’s testimony conclusively demonstrates that
    he did not elicit the information in response to any
    express or implied agreement with or directive from
    Weaver. Rather, Pladsen obtained the information on
    his own initiative, or, as Pladsen put it, ‘‘on [his] own,’’
    as a ‘‘spur of the moment’’ decision he made when ‘‘the
    opportunity presented itself . . . .’’ This testimony
    alone permitted the trial court to find that Pladsen ‘‘was
    not so much a government agent . . . as he was an
    entrepreneur who hoped to sell information to the gov-
    ernment.’’ (Internal quotation marks omitted.) State v.
    Swinton, supra, 
    268 Conn. 858
    ; see also United States v.
    Birbal, 
    supra,
     
    113 F.3d 346
     (‘‘[t]he [s]ixth [a]mendment
    rights of a talkative inmate are not violated when a
    jailmate acts in an entrepreneurial way to seek informa-
    tion of potential value, without having been deputized
    by the government to question that defendant’’); United
    States v. York, supra, 
    933 F.2d 1356
     (Massiah is not
    violated when ‘‘an individual, acting on his own initia-
    tive, deliberately elicits incriminating information’’
    (internal quotation marks omitted)).
    Moreover, the state’s minimal contact with Pladsen
    and lack of control over his activities provides even
    further support for the trial court’s finding that he was
    not acting as an agent of the state. See Thomas v. Cox,
    supra, 
    708 F.2d 137
     (single meeting between inmate
    and officer, at which officer instructed inmate to listen
    but not to ask questions, did not demonstrate ‘‘requisite
    degree of . . . ongoing cooperation between [the]
    state and [the] witness required to implicate the state’’14
    (internal quotation marks omitted)). Indeed, the police
    involvement in the present case was far less extensive
    than the officer provided ‘‘transportation service’’ that
    this court held was insufficient to establish agency in
    State v. Alexander, supra, 
    197 Conn. 186
    –87. See part
    I B of this opinion.
    Pladsen and Weaver had a single meeting on January
    5, 2007. The police did not seek out Pladsen. It was
    Pladsen who initiated the meeting by representing in
    his December 27, 2006 letter to Weaver that he had
    incriminating information he wanted to provide. Plad-
    sen had no history of serving as an informant, and
    Weaver was completely unaware of Pladsen until
    receiving his letter. The police also did not put Pladsen
    in a position to obtain information from the defendant.
    They were uninvolved in placing Pladsen in the cell
    next to the defendant, and no one instructed Pladsen
    to cultivate a relationship with him. Moreover, following
    their meeting, Weaver had no control over whether, or
    how, Pladsen interacted with the defendant. See, e.g.,
    United States v. Li, 
    55 F.3d 325
    , 328 (7th Cir. 1995)
    (cooperating witness was not government agent when
    ‘‘[t]he evidence demonstrated no government control
    over [the witness’] actions; most importantly, there was
    no control over [the witness’] decision to arrange a
    meeting with [the defendant]’’); United States v. Sur-
    ridge, 
    687 F.2d 250
    , 255 (8th Cir.) (there was no Massiah
    violation when ‘‘[the] police do nothing to direct or
    control or involve themselves in the questioning’’), cert.

    , 
    103 S. Ct. 465
    , 
    74 L. Ed. 2d 614
    (1982).
    I recognize that, as the majority points out, there
    were certain aspects of Weaver’s meeting with Pladsen
    that could serve as evidence of the existence of an
    implied agency relationship. See, e.g., Ayers v. Hudson,
    
    623 F.3d 301
    , 311–12 (6th Cir. 2010) (agency may be
    established through implicit conduct because, other-
    wise, ‘‘the [s]tate [could] accomplish with a wink and
    a nod what it cannot do overtly’’ (internal quotation
    marks omitted)); Commonwealth v. Foxworth, supra,
    
    473 Mass. 158
     (‘‘[a]n agency relationship may arise other
    than by express agreement, and may evolve . . . by
    implication from the conduct of the parties’’ (internal
    quotation marks omitted)). Specifically, Weaver told
    Pladsen that the police were ‘‘always interested’’ in and
    would ‘‘listen’’ to verifiable information, asked Pladsen
    if he would be willing to wear a wire at some point in the
    future, and left Pladsen with his contact information.
    In light of the entire record, however, these facts
    do not justify overturning the trial court’s finding that
    Pladsen was not a state agent. First, none of these
    statements or actions amounts to an express or implied
    request for information or offer of a benefit.15 Second,
    and most important, Pladsen’s testimony demonstrates
    that he did not interpret Weaver’s actions as tacitly
    suggesting that he should obtain information from the
    defendant or that he would receive a benefit for doing
    so.16 Pladsen testified that he and Weaver had no mutual
    understanding or ‘‘meeting of the minds,’’ and that
    ‘‘there was nothing implied . . . there was no implica-
    tion, and there was no contractual agreement of any
    sort.’’ Pladsen further testified that Weaver never told
    him to ask the defendant questions about Weaver’s
    cases or to ‘‘do anything relative to’’ the defendant, that
    he obtained the information from the defendant ‘‘on
    [his] own,’’ and that Weaver had made it ‘‘very clear’’
    that he ‘‘couldn’t do anything’’ or offer any benefits.17
    Whether this court believes Pladsen’s testimony that
    Weaver had not implied to him that he would receive
    a benefit in exchange for information is beside the point.
    The trial court credited Pladsen’s testimony, and this
    court must defer to that credibility assessment on
    appeal.18 I see nothing in the record to suggest that
    Pladsen’s testimony that he and Weaver entered into no
    express or implied quid pro quo was false or mistaken.
    Indeed, Weaver’s account of the meeting was fully con-
    sistent with Pladsen’s account in this regard.19
    On the basis of this evidence—Pladsen’s testimony
    that he was acting on his own initiative rather than in
    response to an express or implied agreement with or
    directive from the state, and the absence of any signifi-
    cant police involvement or control—there is substantial
    evidence in the record to support the trial court’s finding
    that Pladsen was not acting as an agent of the state
    when he elicited the incriminating information from the
    defendant.20
    III
    THE MAJORITY’S ANALYSIS
    Even accepting the majority’s premise that agency
    depends on whether Weaver ‘‘knew or should have
    known’’ that his meeting with Pladsen was likely to
    cause Pladsen to attempt to elicit additional information
    from the defendant, I disagree that such a standard
    has been satisfied in the present case. As previously
    explained, Weaver gave Pladsen no directives and
    offered him no rewards, and even ignored his calls in
    the months following their meeting. Nor is there any
    evidence that Pladsen ever informed Weaver that he
    intended to obtain information from the defendant. This
    is a far cry from Henry, in which the government had
    a long-standing agreement with the informant to pay
    him only when he obtained favorable information and
    specifically directed the informant to approach the
    defendant and to attempt to obtain incriminating state-
    ments.21 See United States v. Henry, 
    supra,
     
    447 U.S. 266
    , 270.
    In concluding otherwise, the majority contends, first,
    that Pladsen’s meeting with Weaver ‘‘appears to have
    focused Pladsen’s efforts’’ on this particular case, as
    opposed to the defendant’s other then pending criminal
    matters. I disagree that this is a fair inference on this
    record. Neither Weaver nor Pladsen testified to this
    effect. Although they discussed the defendant’s case
    during their meeting, there is no evidence that Weaver
    was the one to bring it up or that the information Plad-
    sen had hoped to convey to Weaver during this meeting
    concerned only unrelated cases.
    To the contrary, the record suggests that the opposite
    inference is far more reasonable. Pladsen’s letter to
    Weaver dated December 27, 2006, stated that Pladsen
    had ‘‘some information that could be very useful to
    [him] and one of [his] cases.’’ The investigation of the
    victim’s murder was one of Weaver’s cases, and Weaver
    testified at the suppression hearing that, during their
    meeting, Pladsen provided him with information that
    Pladsen had already obtained about the victim’s mur-
    der. This strongly suggests that the ‘‘information’’ Plad-
    sen offered to provide to Weaver in the letter concerned
    this case.22 Moreover, Weaver testified that Pladsen had
    asked whether he would receive a benefit if he provided
    information ‘‘about the [victim’s] investigation,’’ sug-
    gesting that Pladsen was the one to broach the topic.
    On this same point, the majority goes on to conclude
    that Pladsen’s discussion with Weaver must have sug-
    gested to Pladsen that ‘‘the state was principally inter-
    ested in objectively verifiable forms of evidence regard-
    ing the defendant’s involvement in this particular case,
    such as a recording or writing,’’ and that, ‘‘[a]lthough
    Weaver made no explicit requests during this meeting,
    the handwritten note that Pladsen ultimately produced
    during the state’s case-in-chief mirrored those require-
    ments precisely.’’ The majority appears to suggest that
    the similarities between what Pladsen and Weaver dis-
    cussed, and what Pladsen ultimately obtained, indicate
    that Weaver had specifically requested that information.
    I disagree.
    The note hardly ‘‘mirror[s]’’ what Pladsen and Weaver
    discussed in their meeting; it may be consistent with
    what was discussed, but only on the most general of
    levels, i.e., it concerned this case and was ‘‘verifiable’’
    in that it was handwritten by the defendant, as opposed
    to being based on Pladsen’s word alone. This does not
    evidence the existence of an agency relationship. If
    Weaver had mentioned a specific detail in the case,
    such as the type of weapon used in the murder, and
    Pladsen returned with information about that specific
    detail, it might have suggested that Weaver had
    requested that information. See Ayers v. Hudson, 
    supra,
    623 F.3d 315
    –16 (inferring agency relationship when
    informant ‘‘knew exactly what questions to ask [the
    defendant] regarding the details of the murder’’ after
    meeting with police). Nothing of the sort occurred here;
    Pladsen and Weaver discussed the victim’s case in only
    general terms. In any event, Pladsen’s testimony at the
    suppression hearing forecloses any claim that Weaver
    suggested that he obtain any information, verifiable or
    otherwise, from the defendant. See part II of this opin-
    ion.
    Second, the majority places substantial significance
    in the fact that Pladsen ‘‘sought assurance from Weaver
    that a benefit would be made available in exchange for
    his cooperation.’’ The fact that Pladsen hoped or even
    expected to receive a benefit, however, did not render
    him an agent. ‘‘We must not confuse speculation about
    [an informant’s] motives for assisting the police for
    evidence that the police promised [the informant] con-
    sideration for his help or, otherwise, bargained for his
    active assistance. [The informant’s] motives alone can-
    not make him an agent of the police even if the police
    knew and understood that his motives probably were
    self-serving and related to getting police cooperation
    in his own case.’’ Lightbourne v. Dugger, 
    829 F.2d 1012
    ,
    1021 (11th Cir. 1987), cert. denied, 
    488 U.S. 934
    , 
    109 S. Ct. 329
    , 
    102 L. Ed. 2d 346
     (1988). Indeed, ‘‘most inmates
    who provide information to law enforcement officials
    harbor the hope that their service will not go unre-
    warded. . . . That inmates realize there is a market for
    information about crime does not make each inmate
    who enters the market a government agent.’’ (Citation
    omitted.) United States v. York, supra, 
    933 F.2d 1357
    ;
    see also State v. Swinton, supra, 
    268 Conn. 858
    –59.
    Relatedly, the majority appears to suggest that
    Weaver encouraged Pladsen’s hope of receiving a bene-
    fit. As the basis for this assertion, the majority contends
    that, although Weaver told Pladsen that he could not
    offer any deals or benefits, Weaver ‘‘(1) informed Plad-
    sen 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.’’ I
    disagree.
    Even if Weaver had said these things to Pladsen,
    which is not clearly borne out by the record,23 it would
    not change the analysis. Courts have addressed similar
    statements and held that, without more, they do not
    establish agency. See, e.g., United States v. Taylor, 
    800 F.2d 1012
    , 1015 (10th Cir. 1986) (statements to jailhouse
    informant that information about cooperation would
    be ‘‘passed on’’ to appropriate authorities were insuffi-
    cient to demonstrate agency in absence of agreement
    or offer of benefit (internal quotation marks omitted)),
    cert. denied, 
    484 U.S. 838
    , 
    108 S. Ct. 123
    , 
    98 L. Ed. 2d 81
     (1987); Commonwealth v. Foxworth, supra, 
    473 Mass. 157
    –58 (there was no implied agency, despite
    police statements to jailhouse informant that informa-
    tion provided would be forwarded to officials with deal-
    making capacity, when police made no express or
    implied promises).
    If anything, the record reflects that Pladsen was
    merely acting in accordance with his own long-standing
    desire to curry favor with law enforcement when he
    elicited the statements from the defendant. In August,
    2006, months before meeting with Weaver, Pladsen
    began cultivating a relationship with the defendant for
    the specific purpose of using that relationship to coax
    the defendant into divulging incriminating information
    that he could then provide to law enforcement in
    exchange for favorable treatment. Once Pladsen did so,
    he initiated the meeting with Weaver, hoping Weaver
    could help him secure a reduction in the twenty-five
    year sentence he was serving for assaulting a prison
    guard.
    Far from encouraging that hope, Weaver made
    ‘‘clear’’ to Pladsen that he could not provide him with
    any deals or benefits. Pladsen testified that this admon-
    ishment had the effect of discouraging any hope or
    expectation that he would receive anything in exchange
    for his cooperation. See footnote 17 of this opinion and
    accompanying text. Moreover, Pladsen testified—and
    the trial court credited—that he obtained the informa-
    tion from the defendant on his own accord. Accordingly,
    it is pure speculation to conclude, on this record, that
    ‘‘the animating force for securing [the] information
    [was] . . . attributable to the [state]’’; Schmitt v. True,
    
    387 F. Supp. 2d 622
    , 640 (E.D. Va. 2005), aff’d sub nom.
    Schmitt v. Kelly, 
    189 Fed. Appx. 257
     (4th Cir.), cert.
    denied, 
    549 U.S. 1028
    , 
    127 S. Ct. 577
    , 
    166 L. Ed. 2d 425
     (2006); rather than to Pladsen’s own preexisting,
    subjective hope that he might obtain a benefit. Pladsen
    conducted himself exactly the same way before his
    meeting with Weaver as he did after it.
    Third, the majority contends that the fact that the
    state did not object to Pladsen’s subsequent attempt to
    obtain a reduction in his sentence is relevant because
    it amounts to the provision of a benefit. Under the
    specific circumstances of the present case, I disagree.
    To have any bearing on the agency analysis, the benefit
    must have ‘‘already been promised at the time the infor-
    mant elicited the information; if not, later receipt of a
    benefit is of no consequence.’’ Manns v. State, supra,
    
    122 S.W.3d 188
    ; see also Creel v. Johnson, supra, 
    162 F.3d 393
     (decision of police not to prosecute was irrele-
    vant to agency because there was no evidence that
    ‘‘anyone promised . . . not to pursue [the] charges in
    exchange for [the informant’s] assistance’’ (emphasis
    added)); Lightbourne v. Dugger, 
    supra,
     
    829 F.2d 1020
    –21 (agreement to assist informant in obtaining
    bail did not create agency relationship because it was
    not made until after informant elicited incriminating
    statements); Commonwealth v. Foxworth, supra, 
    473 Mass. 158
    –59 (fact that informant received favorable
    treatment was irrelevant to agency ‘‘[in the absence of]
    evidence that such treatment had been promised in
    exchange for information yet to be obtained’’).
    Although I agree with the majority that the subse-
    quent receipt of a benefit can, under some circum-
    stances, serve as circumstantial evidence that an agency
    relationship previously had existed, or that the benefit
    previously had been offered, the record in this case
    forecloses any such inference. Pladsen’s testimony at
    the suppression hearing, which, again, this court must
    accept because the trial court credited it, was that
    Weaver offered him no benefits during their January 5,
    2007 meeting. Weaver testified to the same effect.
    Weaver and Pladsen had no further direct communica-
    tions until months later, after Pladsen had obtained
    the note.
    Moreover, Pladsen testified at the defendant’s trial
    that he was not expecting to receive a benefit because
    Weaver had disclaimed any authority to provide him
    with any benefit. See footnote 17 of this opinion. This
    evidence demonstrates that any benefit Pladsen ulti-
    mately received for his assistance had not been offered
    to him before he elicited the incriminating information
    from the defendant. In fact, this evidence strongly sug-
    gests that the state’s decision to provide Pladsen with
    a benefit had not even been made until after he obtained
    the statements. Accordingly, Pladsen’s later receipt of
    a benefit does not provide any evidence of agency.
    Finally, the majority relies on the fact that the defen-
    dant was incarcerated when Pladsen elicited the incrim-
    inating statements from him. The majority cites the
    United States Supreme Court’s observation in United
    States v. Henry, 
    supra,
     
    447 U.S. 274
    , that ‘‘the mere fact
    of custody imposes pressures on the accused; confine-
    ment may bring into play subtle influences that will
    make him particularly susceptible to the ploys of under-
    cover [g]overnment agents.’’ The fact of custody, how-
    ever, although relevant to the deliberate elicitation
    prong of a Massiah claim, has no bearing on the thresh-
    old question of agency, which focuses not on the sus-
    ceptibility of the defendant to ploys, but on the ‘‘extent
    of police involvement with the informant.’’ State v. Alex-
    ander, supra, 
    197 Conn. 184
    .
    Indeed, the United States Supreme Court clarified in
    a footnote that ‘‘the fact of custody bears on whether
    the [g]overnment ‘deliberately elicited’ the incriminat-
    ing statements from [the defendant].’’ United States v.
    Henry, 
    supra,
     
    447 U.S. 274
     n.11. Relying on this foot-
    note, the United States Court of Appeals for the District
    of Columbia held that ‘‘it is of no moment that the incrim-
    inating conversations took place while the accused was
    incarcerated’’ because the fact of custody is relevant
    only to the question of deliberate elicitation and ‘‘does
    not bear [on] the anterior question whether th[e] [infor-
    mant] was acting on behalf of the [g]overnment [which]
    depends solely [on] whether he was acting [on] the
    instruction of a government official.’’ United States v.
    Watson, 
    supra,
     
    894 F.2d 1347
    –48; see also United States
    v. Johnson, 
    196 F. Supp. 2d 795
    , 855, 860 (N.D. Iowa
    2002) (fact that defendant was in custody demonstrated
    deliberate elicitation but was not relevant to agency),
    rev’d on other grounds, 
    338 F.3d 918
     (8th Cir. 2003);
    Wallace v. Price, Docket No. 99-231, 
    2002 WL 31180963
    ,
    *68 and n.54 (W.D. Pa. October 1, 2002) (fact of custody
    relates to ‘‘the mental state of the defendant, his vulner-
    ability while incarcerated, his susceptibility to artifice,
    and the likelihood that he will expose incriminating
    information to others,’’ none of which is relevant to
    agency); State v. Willis, supra, 
    496 S.W.3d 714
     (fact
    of incarceration ‘‘do[es] not bear on the question of
    whether [the informant] was acting as a government
    agent’’).24 The fact that the defendant was in custody
    when Pladsen elicited the incriminating information
    from him, although pertinent to whether the statements
    were deliberately elicited, is simply not relevant to the
    question of whether Pladsen was an agent of the state.
    For these reasons, I see no basis in the record to
    conclude that Weaver knew or should have known that
    his meeting with Pladsen or his subsequent telephone
    call with him; see footnote 20 of this opinion; as opposed
    to Pladsen’s obvious own preexisting desire to provide
    the police with information in exchange for leniency,
    was likely to result in Pladsen’s seeking further informa-
    tion from the defendant. Accordingly, I would not con-
    clude that Pladsen was a state agent, even under the
    majority’s new formulation of the agency standard.
    IV
    CONCLUSION
    In summary, courts should always scrutinize law
    enforcement’s dealings with jailhouse informants to
    ensure that the state is not circumventing criminal
    defendants’ sixth amendment rights by ‘‘a wink and a
    nod . . . .’’ Ayers v. Hudson, 
    supra,
     
    623 F.3d 312
    . At
    the same time, not every encounter between the police
    and an inmate establishes an agency relationship so as
    to render inadmissible any incriminating information
    that the inmate subsequently obtains from the defen-
    dant. ‘‘[A]ll citizens . . . have a duty to report informa-
    tion about criminal activities, and [although] the [s]ixth
    [a]mendment may limit the government’s ability to
    encourage such reporting behavior, the government
    should not be required to actively discourage such
    behavior either.’’ (Emphasis in original; internal quota-
    tion marks omitted.) State v. Willis, supra, 
    496 S.W.3d 713
    ; see also United States v. Johnson, supra, 
    4 F.3d 912
     (‘‘we decline to handicap legitimate investigations
    by assuming that any time the government is
    approached by a would-be informant and eventually
    uses evidence obtained by that informant, an implicit
    agency relationship is established’’); United States v.
    Malik, 
    680 F.2d 1162
    , 1165 (7th Cir. 1982) (rejecting
    argument that ‘‘[g]overnment must go to extraordinary
    lengths to protect defendants from their own loose
    talk’’).
    Under today’s decision, which holds that the trial
    court was required to find agency even though the state
    did not affirmatively request information from Pladsen
    or offer any benefit in exchange for that information,
    virtually every inmate who seeks out a state official to
    provide information will be regarded as having become
    an agent of the state unless the official responds with
    complete silence or affirmatively dissuades the inmate
    from seeking further information.25 See Thomas v. Cox,
    supra, 
    708 F.2d 137
     (declining to find agency on basis
    of single meeting between police and inmate at which
    no offers or promises were made, because ‘‘[t]o do so
    would be in practical effect to establish the principle
    that any voluntary proffer of inmate informer assistance
    not met with silence or actually repudiated by state
    officials would make inadmissible any inculpatory dis-
    closures . . . subsequently made by an accused,’’
    which neither Henry nor sixth amendment requires).
    In my view, this stretches Massiah too far.
    For the foregoing reasons, I would conclude that the
    trial court’s finding that Pladsen was not acting as an
    agent of the state is supported by substantial evidence.
    Accordingly, I respectfully dissent in part.
    1
    I agree with and join parts II and III of the majority opinion.
    2
    I have reviewed the numerous other claims of error that the defendant
    has raised in the present case; see footnote 2 of the majority opinion; and
    conclude that none of them warrants a reversal of any of his convictions,
    either because they lack merit, or because they constitute harmless error.
    With respect to the trial court’s improper failure to instruct the jury on
    third-party culpability; see part III of the majority opinion; I would conclude
    that, assuming without deciding that such errors are subject to the constitu-
    tional harmless error standard; see State v. Arroyo, 
    284 Conn. 597
    , 614, 
    935 A.2d 975
     (2007); the error was harmless beyond a reasonable doubt. The
    absence of the instruction did not preclude the defendant from advancing
    his third-party culpability defense, as evidence of third-party culpability—
    DNA from unknown individuals found on the victim and around her apart-
    ment—was admitted into evidence at trial, and defense counsel argued
    during closing argument that one of these unknown individuals could have
    killed the victim. Further, the state’s case against the defendant was strong.
    Among other things, the defendant’s DNA was found on the vaginal swab
    taken from the victim and he provided a written, sworn statement to the
    police in which he confessed in detail to having stabbed and strangled the
    victim. See footnote 5 of the majority opinion and accompanying text.
    3
    After referencing the substantial evidence test, the majority observes in
    the very next sentence that, ‘‘to the extent that the resolution of [the agency]
    question calls for application of the controlling legal standard to the histori-
    cal facts, it presents a . . . question of law . . . which [this court reviews]
    de novo.’’ (Internal quotation marks omitted.) As support for this proposition,
    the majority quotes State v. Castillo, 
    329 Conn. 311
    , 322–23, 
    186 A.3d 672
    (2018), a decision addressing whether the defendant was in custody for
    purposes of a fifth amendment claim, which is an issue that, unlike the
    issue of agency, has long been recognized as a mixed question of law and
    fact subject to de novo review.
    4
    As a justification for its departure from this court’s prior cases, the
    majority notes that ‘‘questions of law abound in [the] context’’ of an agency
    analysis. See footnote 19 of the majority opinion. But Alexander and its
    progeny were not incorrect in applying substantial evidence review merely
    because the question of agency involves the application of a legal standard.
    Many disputed issues require a legal standard to be applied to underlying
    facts, yet are not treated as questions of law subject to de novo review.
    See, e.g., Ferndale Dairy, Inc. v. Geiger, 
    167 Conn. 533
    , 537–38, 
    356 A.2d 91
     (1975) (‘‘it [was] a question of fact to be determined by the jury in applying
    established legal principles whether the manner in which the [defendant’s]
    car was operated and brought to a stop was the proximate cause of the
    accident’’).
    5
    There also are federal courts of appeals that, consistent with Connecticut
    case law, treat the ultimate finding of agency as a question of fact. See
    United States v. Li, 
    55 F.3d 325
    , 328 (7th Cir. 1995); United States v. Van
    Scoy, 
    654 F.2d 257
    , 261 (3d Cir.), cert. denied, 
    454 U.S. 1126
    , 
    102 S. Ct. 977
    ,
    
    71 L. Ed. 2d 114
     (1981).
    6
    The trial court rejected the defendant’s claim that Pladsen’s testimony
    at the suppression hearing should be discounted in light of his extensive
    criminal history and mental health issues. Instead, the trial court observed
    that his testimony was ‘‘intelligent and responsive . . . .’’ The trial court
    then found: ‘‘[T]he court had sufficient evidence to assess the credibility of
    Pladsen’s hearing testimony, and the court did credit Pladsen’s testimony.’’
    7
    The majority’s characterization of Henry as a case in which the informant
    ‘‘previously had been paid for providing information,’’ fails to adequately
    capture how clear and indisputable the agency relationship was in that case.
    The informant in Henry had not merely been paid for information in the
    past; he also was subject to a formal, ongoing agreement with government
    officials under which he would be compensated if, and only if, he provided
    information that proved to be favorable. See United States v. Henry,

    The majority suggests that Alexander was overruled by the United States
    Supreme Court’s subsequent decision in Maine v. Moulton, 
    supra,
     
    474 U.S. 171
    , which recognized the police’s ‘‘affirmative obligation’’ not to circumvent
    defendants’ sixth amendment right to counsel. I disagree. As with Henry,
    Moulton involved a clear and indisputable case of agency and was decided
    solely on the basis of the ‘‘deliberate elicitation’’ prong of Massiah. The
    informant in Moulton had entered into an agreement to assist the police
    in their investigation in exchange for leniency and, acting under police
    instruction, secretly recorded a series of conversations between him and
    his codefendant. 
    Id.,
     163–64. The sole question in that case was whether
    the informant had not ‘‘deliberately elicited’’ the statements because the
    codefendant, rather than the informant, had been the one to initiate the
    conversations. 
    Id.,
     174–75. Because agency was not at issue, Moulton neither
    overruled nor abrogated this court’s discussion of agency principles in Alex-
    ander. See Creel v. Johnson, supra, 
    162 F.3d 393
     (defendant’s ‘‘reliance on
    Moulton [for applicable agency standard] is misplaced because Moulton,
    which involved a clear case of agency, addressed the different issue of
    whether the prohibition on using undisclosed agents to ‘deliberately elicit’
    information extended to [when] the accused initiates contact with the
    agent’’); United States v. Li, supra, 
    55 F.3d 328
     (reference in Moulton to
    government’s ‘‘affirmative obligation’’ to preserve sixth amendment rights
    did not affect agency analysis because agency was not at issue); Common-
    wealth v. Murphy, 
    448 Mass. 452
    , 460, 
    862 N.E.2d 30
     (2007) (‘‘[a]gency was
    not a contested issue in . . . Moulton’’ (citation omitted)); State v. Willis,
    supra, 
    496 S.W.3d 709
     and n.19 (Moulton addressed only deliberate elicitation
    and was irrelevant to agency); Manns v. State, 
    122 S.W.3d 171
    , 179 (Tex.
    Crim. App. 2003) (‘‘Moulton . . . adds little to the present discussion
    [regarding agency]’’).
    10
    In addition to concluding that Alexander was overruled by Moulton;
    see footnote 9 of this opinion; the majority writes Alexander off as being
    of ‘‘limited utility’’ in the present case because the informant in Alexander
    (1) had not been offered anything in exchange for his cooperation, and
    (2) was not an inmate. Neither of these factors provides a valid basis for
    distinguishing Alexander. Although it is true that the informant in Alexander
    was offered no reward in exchange for information, the same is true of
    Pladsen in the present case. Weaver testified that he offered Pladsen no
    benefits or deals. Similarly, Pladsen testified that Weaver had offered him
    no benefits and, in fact, told him that he lacked authority to do so, and the
    trial court credited that testimony. This court cannot second-guess that
    credibility determination on appeal. See part III of this opinion.
    I also disagree that Alexander is inapplicable merely because the infor-
    mant in that case was not an inmate. As I explain more fully in part III of
    this opinion, courts have consistently recognized that, although the fact
    of incarceration is relevant to whether the statements were ‘‘deliberately
    elicited,’’ it is not relevant to whether the informant was an agent. See, e.g.,
    United States v. Watson, 
    supra,
     
    894 F.2d 1347
    –48.
    Moreover, I do not subscribe to the view that the informant in Alexander
    had less of an incentive to cooperate with the police than Pladsen (or the
    average jailhouse informant) and, thus, could not as easily become an agent
    of the state, merely because he was not incarcerated. Although inmates
    have obvious incentives to obtain information from fellow inmates to provide
    to the police, individuals who are not incarcerated often have strong incen-
    tives of their own to cooperate with law enforcement. See State v. Bruneau,
    
    131 N.H. 104
    , 110, 
    552 A.2d 585
     (1988) (Souter, J.) (observing that inducement
    giving rise to agency relationship under Massiah ‘‘may derive its force from
    any one of a wide variety of [third-party] interests: the good citizen may
    respond from a sense of civic obligation, while the common informer may
    be looking for prosecutorial leniency or even payment in cash’’). Indeed,
    there was evidence that this was especially true of the informant in Alexan-
    der, who was friends with the missing victim that the defendant had admitted
    to murdering, and whose visits with the defendant admittedly were ‘‘moti-
    vated, at least in part, by a feeling of responsibility toward the police.’’ State
    v. Alexander, supra, 
    197 Conn. 182
    , 187. I would not provide incarcerated
    defendants with diminished sixth amendment protections merely because
    the informant who seeks information from them is not a fellow inmate.
    11
    The majority cites a number of cases that, in its view, support the
    proposition that the ‘‘must have known’’ standard from Henry governs the
    agency analysis. I respectfully disagree with the majority’s characterization
    of these cases. Although a number of them discuss Henry, none of them
    holds, as the majority does today, that an informant becomes a government
    agent merely because the police ‘‘must have known’’ that their conversation
    with an informant might result in that informant’s seeking information from
    the defendant. Rather, consistent with the case law cited in the body of this
    opinion, these cases all recognize that the critical inquiry is whether the
    informant was acting pursuant to an express or implied agreement with
    police. See Ayers v. Hudson, 
    623 F.3d 301
    , 310–16 (6th Cir. 2010) (observing
    that agency may be established with evidence of either explicit directive to
    obtain information or ‘‘implied agreement,’’ and concluding that agency had
    been demonstrated by evidence showing that informant and police ‘‘were
    working in conjunction with each other’’ to elicit information from defen-
    dant); Randolph v. California,

    Massiah and concluding that informant acted as state agent when police
    had returned him to cell that he shared with defendant after he had met

    defendant, because evidence demonstrated that state ‘‘made a conscious
    decision to obtain [the informant’s] cooperation and that [the informant]
    consciously decided to provide that cooperation’’); Matteo v. Superinten-

    Pladsen testified:
    ‘‘[Defense Counsel]: When Detective Weaver gave you his business card
    with the numbers you described, is it correct it was your understanding
    that if you were to obtain any information about [the defendant] that you
    were to contact him?
    ‘‘[Pladsen]: I don’t think that would be a proper way of saying it because
    that implies that we had some type of an agreement. What I would say
    that what [Weaver] did was hey . . . if you want to contact me again,
    because like I told you some of the time when he was up there we just kind
    of talked about . . . different things like . . . he was telling me about the
    Internet because I’ve never seen the Internet . . . I don’t know what that’s
    about. So he was kind of friendly, but it could have been for just a casual
    conversation. There was nothing implied one way or the other. It’s not
    saying he would come up and b[e] my friend. I’m not saying that either, but
    I’m saying it wasn’t implied one way or the other. There was no implication
    and there was no contractual agreement of any sort.
    ‘‘[Defense Counsel]: Didn’t have a meeting of the minds?
    ‘‘[Pladsen]: Right. . . . There’s no meeting of the minds, no.’’ (Empha-
    sis added.)
    13
    Likewise, Weaver testified that he made ‘‘clear’’ to Pladsen that he lacked
    authority to enter into any deals or offer any benefits of any kind.
    14
    In this case, the question of whether an officer’s instruction to ‘‘listen
    but not ask questions’’ is sufficient to create an agency relationship is not
    at issue. Unlike the officer in Thomas, Weaver did not instruct Pladsen to
    listen for information, or to do anything relative to the defendant. Weaver
    testified that he merely told Pladsen that he ‘‘would be willing to listen’’ to
    any information Pladsen wanted to provide. The present case thus, presents
    an even weaker case for agency than the one rejected by the United States
    Court of Appeals for the Fourth Circuit in Thomas. See footnotes 15 and
    18 of this opinion.
    15
    Any reliance on Weaver’s statement that the police were ‘‘always inter-
    ested’’ in and would ‘‘listen’’ to verifiable information as proof of agency is
    especially dubious because it is not even clear that Weaver made this state-
    ment in reference to information Pladsen might obtain in the future, as
    opposed to information Pladsen had already obtained but was withholding
    from Weaver. Weaver testified that he had the impression that Pladsen ‘‘knew
    more’’ about the victim’s murder than he had let on during their meeting.
    16
    Even if Pladsen had subjectively believed that any of Weaver’s state-
    ments constituted requests for information, it is unclear that such a belief,
    alone, would have created an agency relationship. See Fairbank v. Ayers,
    
    650 F.3d 1243
    , 1256 (9th Cir. 2011) (‘‘even if [the informant] subjectively
    believed that the officer’s statement [that he was looking for the murder
    weapon] was a request [for that information], this does not constitute the
    requisite state involvement’’), cert. denied, 
    565 U.S. 1276
    , 
    132 S. Ct. 1757
    ,
    
    182 L. Ed. 2d 558
     (2012).
    17
    Weaver’s admonishment that he lacked authority to provide any deals
    or benefits evidently had an impact on Pladsen. At the defendant’s trial, a
    few days after the suppression hearing, Pladsen testified:
    ‘‘[Defense Counsel]: And am I correct that as you sit there now today,
    you’re still hoping for some sort of benefit?
    ‘‘[Pladsen]: No. [Weaver] made it perfectly clear to me that he’s not author-
    ized to do anything of the [sort] on that.’’
    18
    I note that courts have frequently held that, in the absence of an express
    or implied agreement, generalized instructions to listen for information are
    insufficient to demonstrate agency. See, e.g., State v. Alexander, supra, 
    197 Conn. 186
     (‘‘[t]he police had simply asked [the informant] to let them know
    if he heard anything . . . [and] that request alone did not create an agency
    relationship’’); see also Thomas v. Cox, supra, 
    708 F.2d 137
     (admonition to
    ‘‘ ‘keep your ears’ open or to ‘listen but don’t ask’ ’’ was insufficient to
    establish agency ‘‘with no express or implicit quid pro quo undergirding
    it’’). As I have emphasized; see footnote 14 of this opinion; the facts of the
    present case fall even further short of establishing agency than those at
    issue in these prior decisions because Weaver did not instruct Pladsen to
    listen for information (or to do anything at all) but merely said that he
    generally would be willing to listen to whatever information Pladsen was
    willing to provide.
    19
    The majority relies on the Superior Court’s decision in State v. Howell,
    Superior Court, judicial district of New Britain, Docket No. CR-05-222048-
    S (January 30, 2007) (Sheldon, J.), but that case is nothing like the present
    case. First, the Superior Court in Howell, as a trial court viewing the evidence
    on a clean slate, was required to conduct a plenary review of the evidence
    and independently determine whether the informant was a state agent. In
    the present case, however, our appellate review of the trial court’s finding
    that Pladsen was not an agent is far more circumscribed, both by the substan-
    tial evidence rule and by the trial court’s credibility findings. Second, the
    facts of Howell are distinguishable. In Howell, during a telephone conversa-
    tion with the informant, the officer affirmatively instructed the informant
    to listen to incriminating information the defendant was providing, and even
    told the informant that their conversation had made him an agent of the
    state. See 
    id.
     There are no such facts in the present case.
    20
    The majority contends that, even if Pladsen had not become a state
    agent as a result of his January 5, 2007 meeting with Weaver, ‘‘surely, such
    a relationship would have been established after Pladsen offered, and the
    state affirmatively accepted,’’ the note that Pladsen elicited from the defen-
    dant. Footnote 34 of the majority opinion. After Pladsen read the note to
    Weaver over the telephone, Pladsen was confronted by the defendant, who
    was angry that Pladsen had given the note to Weaver and asked Pladsen
    to falsely claim authorship of the note. The majority contends that the
    elicitation of this statement itself constitutes a Massiah violation that inde-
    pendently justifies a reversal of the defendant’s convictions. 
    Id.
     I disagree.
    There is no evidence that Weaver said or did anything during that call
    with Pladsen to suggest that he wanted Pladsen to obtain any additional
    information from the defendant. Weaver merely accepted the information
    Pladsen provided to him, which does not establish agency. See State v.
    Willis, 
    supra,
     
    496 S.W.3d 712
    –13 (‘‘[t]he government’s willing acceptance of
    information provided . . . by an . . . informant did not make the infor-
    mant the government’s agent under the [s]ixth [a]mendment’’ (internal quota-
    tion marks omitted)); Manns v. State, supra, 
    122 S.W.3d 189
     (government’s
    ‘‘accept[ance] [of] the information [the informant] had to offer’’ was insuffi-
    cient to establish agency).
    21
    I respectfully disagree with the majority’s suggestion that ‘‘Weaver told
    Pladsen that he was interested in hearing new evidence relating to the
    victim’s death . . . .’’ I see no evidence of any such statement in the record.
    Although Weaver asked if Pladsen would be willing to wear a wire sometime
    in the future should the Office of the State’s Attorney authorize such an
    operation, this is hardly the same thing as telling Pladsen that he himself
    was ‘‘interested in hearing new evidence’’ about the victim’s death. Again,
    Pladsen’s own testimony at the suppression hearing demonstrates he did
    not interpret Weaver’s comment in this manner. See part II of this opinion.
    22
    The majority contends that Pladsen’s December 27, 2006 letter to Weaver
    ‘‘referenced only unrelated criminal charges.’’ Although the majority is cor-
    rect in noting that certain other references in the letter concerned unrelated
    cases; see footnote 30 of the majority opinion; there is no indication that
    Pladsen’s reference to ‘‘information that might be very useful’’ was not
    related to this case.
    23
    I disagree with the majority that the record reflects that Weaver made
    either of these statements to Pladsen. As to the first statement, Weaver
    testified that he never mentioned to Pladsen anything about what the Office
    of the State’s Attorney ‘‘could or could not do’’ in terms of approving deals
    or offering benefits.
    As to the second statement, the record is, at best, unclear as to whether
    Weaver told Pladsen that he would convey any information he received to
    the Office of the State’s Attorney. Pladsen testified that Weaver did not make
    any such statement. Weaver testified to similar effect but was somewhat
    equivocal. He testified:
    ‘‘[Defense Counsel]: Did you indicate to . . . Pladsen that you would
    report any information you got from him to the [Office of the State’s Attor-
    ney]?
    ‘‘[Weaver]: No.
    ‘‘[Defense Counsel]: Didn’t make that clear to him?
    ‘‘[Weaver]: No. I didn’t tell him that, if you tell me something right now,
    I’m going to go back and tell the [Office of the State’s Attorney]. I listened
    to what he had to say.
    ‘‘[Defense Counsel]: Isn’t it a fact that you indicated to him that any
    contact you had with him would have to be reported to [the Office of the
    State’s Attorney]?
    ‘‘[Weaver]: I did tell him that because I wanted to make sure that the
    [Office of the State’s Attorney] knew that I was having contact with someone
    about an ongoing case they’re investigating, so I thought it was important.
    ‘‘[Defense Counsel]: All right. So you made him generally aware that any
    contact you had and any information received would go to the [Office of
    the State’s Attorney]?
    ‘‘[Weaver]: Yes.’’
    24
    Although the Third Circuit Court of Appeals suggested that custody is
    relevant to the agency analysis in Matteo v. Superintendent, SCI Albion,
    
    171 F.3d 877
    , 894–95 (3d Cir.), cert. denied sub nom. Matteo v. Brennan,

     (1999), this aspect of Matteo
    has been widely criticized as being based on a misreading of Henry. See
    United States v. Johnson, supra, 
    196 F. Supp. 2d 855
    , 860 (generally relying
    on Matteo but noting that ‘‘[t]he court in Matteo may have gone too far’’
    when it considered custody as relevant to agency); Wallace v. Price, supra,

    that [this factor was] pertinent to the question of agency, rather than the
    question of interrogation or deliberate elicitation.’’ (Citation omitted.)).
    25
    I endorse the majority’s assurance in footnote 24 of its opinion that
    some affirmative action on the part of the state is necessary in order to
    establish an agency relationship. I find it difficult, however, to reconcile
    this assurance with the majority’s analysis in the present case, which relies
    in substantial part on innocuous statements Weaver made to Pladsen, as
    well as on Weaver’s failure to affirmatively dissuade Pladsen from seeking
    further information.
