    STATE OF CONNECTICUT v. ADA MANGUAL
    (SC 18842)
    Rogers, C. J., and Norcott, Palmer, Zarella, Eveleigh and Vertefeuille, Js.*
    Argued December 4, 2012—officially released March 4, 2014
    Alice Osedach, assistant public defender, for the
    appellant (defendant).
    Leon F. Dalbec, Jr., senior assistant state’s attorney,
    with whom, on the brief, were Brian Preleski, state’s
    attorney, and Brett J. Salafia, assistant state’s attorney,
    for the appellee (state).
    Opinion
    PALMER, J. A jury found the defendant, Ada Mangual,
    guilty of possession of narcotics with the intent to sell
    by a person who is not drug-dependent in violation
    of General Statutes § 21a-278 (b), and possession of
    narcotics with the intent to sell within 1500 feet of a
    public school in violation of General Statutes § 21a-278a
    (b), following a police investigation that culminated in
    the seizure of a quantity of heroin from the defendant’s
    home pursuant to a duly authorized search warrant.
    The trial court rendered judgment in accordance with
    the jury verdict and imposed a total effective sentence
    of eight years imprisonment. On appeal to the Appellate
    Court, the defendant challenged, inter alia, the trial
    court’s denial of her motion to suppress certain state-
    ments, claiming that those statements had been
    obtained in violation of her rights under the fifth and
    fourteenth amendments to the United States constitu-
    tion when a police officer questioned her during the
    execution of the search warrant without first advising
    her of her rights under Miranda v. Arizona, 
    384 U.S. 436
    , 
    86 S. Ct. 1602
    , 
    16 L. Ed. 2d 694
    (1966).1 The Appellate
    Court rejected the defendant’s claim upon concluding
    that the trial court properly determined that the defen-
    dant was not in custody for purposes of Miranda at
    the time of the police questioning and that, as a result,
    Miranda warnings were not required. See State v. Man-
    gual, 
    129 Conn. App. 638
    , 642, 648–49, 
    21 A.3d 510
    (2011). The Appellate Court therefore affirmed the judg-
    ment of the trial court; 
    id., 651; and
    we granted the
    defendant’s petition for certification to appeal, limited
    to the following issue: ‘‘Did the Appellate Court properly
    conclude that the defendant was not in custody for
    purposes of Miranda when a police officer interrogated
    her during the execution of a search warrant on her
    residence?’’ State v. Mangual, 
    302 Conn. 916
    , 
    27 A.3d 368
    (2011). We agree with the defendant that she was
    in custody when the officer questioned her and, conse-
    quently, that the police were required to advise her in
    accordance with Miranda. Because we also agree with
    the defendant that the Miranda violation was not harm-
    less beyond a reasonable doubt, we conclude that the
    defendant is entitled to a new trial. We therefore reverse
    the judgment of the Appellate Court.
    The opinion of the Appellate Court sets forth the
    following facts that are relevant to the defendant’s
    claim. ‘‘In January, 2008, Officer John Blackmore of
    the New Britain [P]olice [D]epartment (department)
    received information from a confidential informant that
    heroin was being sold from an apartment in a multifam-
    ily residence located on North Street in [the city of] New
    Britain. After receiving this information, the department
    began surveillance of the apartment. In addition to sur-
    veillance, the department also used confidential infor-
    mants to make three controlled purchases of heroin
    from the apartment. On the basis of information gath-
    ered from these investigative activities, the department
    suspected that three individuals, including a Hispanic
    male named ‘Bebo’ and a woman named ‘Ada,’ were
    selling heroin from the apartment.
    ‘‘Blackmore obtained a search and seizure warrant
    for the apartment, which the police executed on Febru-
    ary 5, 2008. In executing the warrant, Blackmore and
    [three] other officers [who were equipped with hand-
    guns, tactical vests, and at least one rifle] entered the
    multifamily residence and proceeded to the apartment,
    while Officer Gerald Hicks . . . and two other uni-
    formed officers remained outside. After reaching the
    apartment, an officer knocked on the front door and
    advised the occupants of the warrant. The defendant
    answered the door and allowed the officers [to enter,
    some of whom did so with their weapons drawn]. Upon
    entry, the officers [removed the defendant’s dog from
    the four room apartment and guided] the defendant and
    [her three daughters] into the living room area.2 [All
    four occupants were ordered to remain on the couch
    in the living room and were kept under police observa-
    tion for the duration of the search.]
    ‘‘After the apartment was secured, Hicks [and the
    two other officers] proceeded inside. Without issuing
    a Miranda warning [or informing the defendant
    whether she was under arrest or merely being detained
    temporarily until the officers completed the search],
    Hicks asked the defendant ‘if there [were] any drugs
    or weapons in the apartment.’ ’’ (Footnotes altered.)
    State v. 
    Mangual, supra
    , 
    129 Conn. App. 640
    –41. ‘‘The
    defendant answered ‘yes’ and informed [Hicks] that
    ‘[there were] drugs in the bedroom.’ Thereafter, the
    defendant led Hicks to her bedroom . . . [where she]
    pointed [to a] can of hairspray’’; 
    id., 643; that
    was
    ‘‘located on her dresser and stated that it contained
    heroin. After removing the can’s false bottom, Hicks
    discovered 235 packets of heroin.3 The defendant was
    placed under arrest.’’4 (Footnote added.) 
    Id., 641. Prior
    to trial, the defendant filed a motion to suppress
    her statements in response to Hicks’ inquiry on the
    ground that she had not been advised of her Miranda
    rights before being questioned.5 After an evidentiary
    hearing on the motion, the trial court determined that
    the defendant was not in custody when Hicks ques-
    tioned her and, consequently, that the police were not
    required to issue Miranda warnings. In support of its
    brief oral ruling, the trial court stated that, ‘‘although
    [the defendant] was confined to a certain area,’’ she
    was not handcuffed, and the police ‘‘had every right to
    secure the apartment and . . . to ensure their safety
    by . . . making everyone stay where they were.’’ In
    accordance with this ruling, Hicks was permitted to
    testify at trial that the defendant had told him that there
    were drugs in her bedroom and that she had led him
    to the hairspray can on her dresser that contained those
    drugs. The jury subsequently found the defendant guilty
    of possession of narcotics with the intent to sell by a
    person who is not drug-dependent and possession of
    narcotics with the intent to sell within 1500 feet of a
    public school.
    On appeal to the Appellate Court, the defendant
    claimed, inter alia, that the trial court improperly denied
    her motion to suppress because she was in custody
    when Hicks questioned her without first issuing
    Miranda warnings.6 State v. 
    Mangual, supra
    , 129 Conn.
    App. 642. The Appellate Court rejected the defendant’s
    claim, concluding that she had not demonstrated, as
    Miranda requires, ‘‘that a reasonable person in the
    defendant’s position would have believed that she was
    in police custody of the degree associated with [a] for-
    mal arrest.’’ 
    Id., 647. In
    reaching this determination, the
    Appellate Court observed that Hicks’ questioning was
    limited in scope and duration, the defendant was in the
    familiar surroundings of her apartment, she was not
    restrained physically, and she had not been threatened
    or told that she was under arrest. 
    Id., 647–48. The
    Appel-
    late Court also relied on Michigan v. Summers, 
    452 U.S. 692
    , 
    101 S. Ct. 2587
    , 
    69 L. Ed. 2d 340
    (1981); see
    State v. 
    Mangual, supra
    , 648; in which the United States
    Supreme Court held that, for purposes of the fourth
    amendment, police executing a search warrant for a
    home may detain the occupants during the search;
    Michigan v. 
    Summers, supra
    , 705; and observed that
    the detention of the respondent in that case was ‘‘sub-
    stantially less intrusive’’ than an arrest. (Internal quota-
    tion marks omitted.) 
    Id., 702. On
    the basis of this
    distinction between a formal arrest and the detention
    of the occupant of a home incident to the execution of
    a search warrant, the Appellate Court reasoned that ‘‘a
    defendant is normally not in custody, and . . .
    Miranda warnings are not required, when he or she is
    detained during the execution of a search warrant.’’
    State v. 
    Mangual, supra
    , 648. The Appellate Court ulti-
    mately concluded that ‘‘the trial court did not make any
    factual findings that would lead [the Appellate Court]
    to conclude that the defendant was subject to greater
    constraints on her freedom of movement than those
    normally occurring during the execution of a search
    . . . warrant.’’ 
    Id. On appeal
    to this court following our grant of certifi-
    cation, the defendant claims that (1) the Appellate Court
    incorrectly concluded that the trial court properly had
    denied her motion to suppress because, contrary to
    the conclusion of those courts, she was in custody for
    purposes of Miranda when Hicks questioned her, and
    (2) the resulting use of her statements by the state
    constituted harmful error requiring a new trial. We
    agree with both of the defendant’s contentions.
    I
    We first address the defendant’s claim that she was
    entitled to suppression of her statements because she
    had not been advised of her Miranda rights before
    Hicks elicited those statements, even though she was
    in police custody at that time. We agree that she was
    in custody, and, therefore, the police were required to
    administer Miranda warnings prior to any questioning.7
    The following principles concerning the requirement
    of Miranda warnings govern our analysis of the defen-
    dant’s claim. Although ‘‘[a]ny [police] interview of [an
    individual] suspected of a crime . . . [has] coercive
    aspects to it’’; Oregon v. Mathiason, 
    429 U.S. 492
    , 495,
    
    97 S. Ct. 711
    , 
    50 L. Ed. 2d 714
    (1977); only an interroga-
    tion that occurs when a suspect is in custody ‘‘heightens
    the risk’’ that statements obtained therefrom are not
    the product of the suspect’s free choice. Dickerson v.
    United States, 
    530 U.S. 428
    , 435, 
    120 S. Ct. 2326
    , 147 L.
    Ed. 2d 405 (2000). This is so because ‘‘the coercion
    inherent in custodial interrogation blurs the line
    between voluntary and involuntary statements . . . .’’
    
    Id. Thus, the
    court in Miranda was concerned ‘‘with
    protecting defendants against interrogations that take
    place in a police-dominated atmosphere, containing
    inherently compelling pressures [that] work to under-
    mine the individual’s will to resist and to compel him
    to speak [when] he would not otherwise do so freely
    . . . Miranda v. 
    Arizona, supra
    , 
    384 U.S. 445
    , 467
    . . . .’’ (Internal quotation marks omitted.) State v. Des-
    Laurier, 
    230 Conn. 572
    , 577–78, 
    646 A.2d 108
    (1994).
    ‘‘By adequately and effectively appris[ing] [a suspect]
    of his rights and reassuring the suspect that the exercise
    of those rights must be fully honored, the Miranda
    warnings combat [the] pressures inherent in custodial
    interrogations. Miranda v. Arizona, [supra, 467]. In so
    doing, they enhance the trustworthiness of any state-
    ments that may be elicited during an interrogation.’’8
    (Internal quotation marks omitted.) In re Terrorist
    Bombings of United States Embassies in East Africa,
    
    552 F.3d 177
    , 202 (2d Cir. 2008); see also State v. Barrett,
    
    205 Conn. 437
    , 447, 
    534 A.2d 219
    (1987) (Miranda warn-
    ings ‘‘significantly enhance [a suspect’s] opportunity
    to make a knowing, intelligent and voluntary decision
    whether to speak or remain silent’’). Consequently,
    ‘‘police officers are not required to administer Miranda
    warnings to everyone whom they question’’; Oregon v.
    
    Mathiason, supra
    , 
    429 U.S. 495
    ; rather, they must pro-
    vide such warnings only to persons who are subject to
    custodial interrogation. See, e.g., Miranda v. 
    Arizona, supra
    , 444. To establish entitlement to Miranda warn-
    ings, therefore, the defendant must satisfy two condi-
    tions, namely, that (1) he was in custody when the
    statements were made, and (2) the statements were
    obtained in response to police questioning.9 E.g., State
    v. Britton, 
    283 Conn. 598
    , 604, 
    929 A.2d 312
    (2007).
    Because the state does not challenge the defendant’s
    contention that her statements were made in response
    to Hicks’ questioning, the issue we must decide in the
    present case is whether the defendant was in custody
    when that questioning occurred.10
    To resolve that issue, we first must consider what it
    means to be in custody for purposes of Miranda, a
    task that quite accurately has been characterized as
    ‘‘slippery . . . .’’ Oregon v. Elstad, 
    470 U.S. 298
    , 309,
    
    105 S. Ct. 1285
    , 
    84 L. Ed. 2d 222
    (1985). ‘‘As used in
    . . . Miranda [and its progeny], ‘custody’ is a term of
    art that specifies circumstances that are thought gener-
    ally to present a serious danger of coercion.’’ Howes v.
    Fields,        U.S.      , 
    132 S. Ct. 1181
    , 1189, 
    182 L. Ed. 2d
    17 (2012). ‘‘In determining whether a person is in
    custody in this sense’’; id.; the United States Supreme
    Court has adopted an ‘‘ ‘objective, reasonable person
    test’ ’’; State v. 
    Britton, supra
    , 
    283 Conn. 604
    ; ‘‘the initial
    step [of which] is to ascertain whether, in light of the
    objective circumstances of the interrogation, Stans-
    bury v. California, 
    511 U.S. 318
    , [323, 
    114 S. Ct. 1526
    ,
    
    128 L. Ed. 2d 293
    ] (1994) . . . a reasonable person
    [would] have felt [that] he or she was not at liberty to
    terminate the interrogation and [to] leave. Thompson
    v. Keohane, 
    516 U.S. 99
    , 112 [
    116 S. Ct. 457
    , 
    133 L. Ed. 2d
    383] (1995).’’ (Internal quotation marks omitted.)
    Howes v. 
    Fields, supra
    , 1189. ‘‘Determining whether an
    individual’s freedom of movement [has been] curtailed,
    however, is simply the first step in the analysis, not the
    last. Not all restraints on freedom of movement amount
    to custody for purposes of Miranda. [Accordingly, the
    United States Supreme Court has] decline[d] to accord
    talismanic power to the freedom-of-movement inquiry,
    Berkemer [v. McCarty, 
    468 U.S. 420
    , 437, 
    104 S. Ct. 3138
    ,
    
    82 L. Ed. 2d 317
    (1984)], and [has] instead asked the
    additional question [of] whether the relevant environ-
    ment presents the same inherently coercive pressures
    as the type of station house questioning at issue in
    Miranda.’’11 (Internal quotation marks omitted.) Howes
    v. 
    Fields, supra
    , 1189–90.
    Of course, the clearest example of custody for pur-
    poses of Miranda occurs when a suspect has been
    formally arrested. As Miranda makes clear, however,
    custodial interrogation includes questioning initiated
    by law enforcement officers after a suspect has been
    arrested or ‘‘otherwise deprived of his freedom of action
    in any significant way.’’ (Emphasis added.) Miranda
    v. 
    Arizona, supra
    , 
    384 U.S. 444
    . Thus, not all restrictions
    on a suspect’s freedom of action rise to the level of
    custody for Miranda purposes; in other words, ‘‘the
    freedom-of-movement test identifies only a necessary
    and not a sufficient condition for Miranda custody.’’
    Maryland v. Shatzer, 
    559 U.S. 98
    , 112, 
    130 S. Ct. 1213
    ,
    
    175 L. Ed. 2d 1045
    (2010). Rather, the ‘‘ultimate inquiry’’
    is whether a reasonable person in the defendant’s posi-
    tion would believe that there was a ‘‘restraint on [her]
    freedom of movement of the degree associated with
    a formal arrest.’’12 (Internal quotation marks omitted.)
    Thompson v. 
    Keohane, supra
    , 
    516 U.S. 112
    . Any lesser
    restriction on a person’s freedom of action is not signifi-
    cant enough to implicate the core fifth amendment con-
    cerns that Miranda sought to address.
    With respect to the issue of whether a person in the
    suspect’s position reasonably would have believed that
    she was in police custody to the degree associated with
    a formal arrest, ‘‘no definitive list of factors governs
    [that] determination,’’ which must be based on ‘‘the
    circumstances of each case . . . .’’ (Internal quotation
    marks omitted.) State v. Jackson, 
    304 Conn. 383
    , 416,
    
    40 A.3d 290
    (2012). ‘‘Because, however, the [court in]
    Miranda . . . expressed concern with protecting
    defendants against interrogations that take place in a
    police-dominated atmosphere containing [inherent]
    pressures [that, by their very nature, tend] to undermine
    the individual’s [ability to make a free and voluntary
    decision as to whether to speak or remain silent] . . .
    circumstances relating to those kinds of concerns are
    highly relevant on the custody issue.’’ (Internal quota-
    tion marks omitted.) 
    Id., 416–17. In
    other words, ‘‘in
    order to determine how a suspect [reasonably] would
    have gauge[d] his freedom of movement, courts must
    examine all of the circumstances surrounding the inter-
    rogation.’’ (Internal quotation marks omitted.) Howes
    v. 
    Fields, supra
    , 
    132 S. Ct. 1189
    . Although this court
    has not been called on to decide whether the totality
    of the circumstances surrounding the execution of a
    search warrant at a suspect’s home rendered the atmo-
    sphere police-dominated for purposes of Miranda, the
    Appellate Court has addressed that issue; see State v.
    Read, 
    132 Conn. App. 17
    , 20–23, 
    29 A.3d 919
    , cert.
    denied, 
    303 Conn. 916
    , 
    33 A.3d 740
    (2011); and we pre-
    viously have considered whether a suspect was in cus-
    tody when he invited the police into his home and
    willingly agreed to speak to them. See State v. Kirby,
    
    280 Conn. 361
    , 394–96, 
    908 A.2d 506
    (2006); see also
    State v. Johnson, 
    241 Conn. 702
    , 719–20, 
    699 A.2d 57
    (1997) (defendant voluntarily met with police in his
    father’s residence). A review of these and related cases
    from this state, as well as federal and sister state cases
    involving the interrogation of a suspect during a police
    search of his residence, reveals the following nonexclu-
    sive list of factors to be considered in determining
    whether a suspect was in custody for purposes of
    Miranda: (1) the nature, extent and duration of the
    questioning; (2) whether the suspect was handcuffed
    or otherwise physically restrained; (3) whether officers
    explained that the suspect was free to leave or not
    under arrest; (4) who initiated the encounter; (5) the
    location of the interview; (6) the length of the detention;
    (7) the number of officers in the immediate vicinity of
    the questioning; (8) whether the officers were armed;
    (9) whether the officers displayed their weapons or
    used force of any other kind before or during ques-
    tioning; and (10) the degree to which the suspect was
    isolated from friends, family and the public.
    Finally, we set forth the standard of review. ‘‘The trial
    court’s determination of the historical circumstances
    surrounding the defendant’s interrogation [entails] find-
    ings of fact . . . which will not be overturned unless
    they are clearly erroneous. . . . In order to determine
    the [factual] issue of custody, however, we will conduct
    a scrupulous examination of the record . . . in order
    to ascertain whether, in light of the totality of the cir-
    cumstances, the trial court’s finding is supported by
    substantial evidence. . . . The ultimate inquiry as to
    whether, in light of these factual circumstances, a rea-
    sonable person in the defendant’s position would
    believe that he or she was in police custody of the
    degree associated with a formal arrest . . . calls for
    application of the controlling legal standard to the his-
    torical facts [and] . . . therefore, presents a . . .
    question of law . . . over which our review is de novo.’’
    (Citations omitted; internal quotation marks omitted.)
    State v. 
    Jackson, supra
    , 
    304 Conn. 417
    . In other words,
    we are bound to accept the factual findings of the trial
    court unless they are clearly erroneous, but we exercise
    plenary review over the ultimate issue of custody.
    With these principles in mind, we turn to the merits
    of the defendant’s claim that she was in custody when
    Hicks questioned her and, therefore, that her statements
    must be suppressed because she was not given Miranda
    warnings. As we have explained, that issue requires us
    to determine, first, whether a reasonable person in the
    defendant’s position would have believed that she was
    free to leave the apartment while the police were exe-
    cuting the search warrant. If the answer to that question
    is yes, the inquiry is over because the defendant cannot
    establish custody for purposes of Miranda. If, however,
    the answer is no, we proceed to the second step of
    the inquiry, which asks whether that same reasonable
    person also would have believed that the police
    restraint on her freedom of action was akin to the
    restraint associated with a formal arrest.
    With respect to the reasonableness of the defendant’s
    belief that she was not free to leave, we agree that her
    subjective understanding was objectively reasonable.13
    Indeed, Hicks acknowledged that, in fact, the defendant
    was not free to leave, and, although she was not
    expressly so informed, the conduct of the police was
    fully consistent with her belief. Put differently, there is
    nothing in the conduct of the police that reasonably
    would have caused her to think otherwise. We need
    not address this issue further, however, in light of our
    determination that, for the reasons discussed herein-
    after, a reasonable person in the defendant’s position
    also would have believed that her freedom of action was
    restricted to the degree associated with a formal arrest.
    Several key factors support the defendant’s con-
    tention that the conduct of the police gave rise to an
    atmosphere of police domination that caused the defen-
    dant to reasonably believe that she was in police cus-
    tody during the search of her apartment. First, the police
    initiated contact with the defendant. ‘‘[W]hen the con-
    frontation between the suspect and the criminal justice
    system is instigated at the direction of law enforcement
    authorities, rather than the suspect, custody is more
    likely to exist.’’ United States v. Griffin, 
    922 F.2d 1343
    ,
    1351 (8th Cir. 1990). In the present case, the defendant
    did not invite the officers into her apartment; rather,
    they entered under the authority of a search warrant,
    an inherently coercive and intimidating police action.
    A wholly unexpected and highly intrusive law enforce-
    ment initiative of this sort is likely to be especially
    alarming when, as in the present case, the suspect is
    confronted by a large contingent of armed officers. Not
    surprisingly, Hicks acknowledged that the defendant
    did, indeed, appear concerned and startled by the
    unfolding events.
    Second, officers brandished their weapons upon
    announcing themselves to the defendant and entering
    her apartment. Although the defendant does not ques-
    tion the propriety of this conduct, an occupant of the
    apartment reasonably would associate such a display
    of force with the compulsion routinely employed by
    police when effecting an arrest. See, e.g., United States
    v. Hashime, 
    734 F.3d 278
    , 283–84 (4th Cir. 2013) (defen-
    dant, who was awakened at gunpoint to find his house
    ‘‘occupied by a flood of armed officers,’’ was deemed
    to be in custody during execution of search warrant);
    United States v. Craighead, 
    539 F.3d 1073
    , 1078, 1085
    (9th Cir. 2008) (defendant was in custody during execu-
    tion of search warrant by eight armed officers, some
    of whom unholstered their weapons in defendant’s pres-
    ence); United States v. Colonna, 
    511 F.3d 431
    , 436 (4th
    Cir. 2007) (defendant reasonably believed that he was
    in custody during execution of search warrant at his
    home when officers ‘‘awakened [him] at gunpoint and
    [kept him] guarded at all times’’); Moss v. State, 
    823 P.2d 671
    , 671–72, 675 (Alaska App. 1991) (defendant
    was in custody when officers in raid gear with weapons
    drawn detained him in his residence incident to execu-
    tion of search warrant); State v. Chevre, Minnesota
    Court of Appeals, Docket No. C5-99-1707 (Minn. App.
    August 8, 2000) (defendant was found to be in custody
    during execution of search warrant at his home after
    he ‘‘was confronted at gunpoint at night by a number
    of police officers as a part of a narcotics investigation’’);
    State v. Burdick, 
    186 Or. App. 460
    , 462, 464, 
    63 P.3d 1190
    (2003) (defendant was in custody after police forcibly
    entered his home with search warrant and ordered him
    and other occupants onto floor at gunpoint); Wass v.
    Commonwealth, 
    5 Va. App. 27
    , 34, 
    359 S.E.2d 836
    (1987)
    (police had defendant in custody when execution of
    search warrant was marked by ‘‘armed display of man-
    power at his home’’). In the present case, numerous
    police officers approached the defendant’s residence
    with a show of force that included drawn handguns,
    one or more rifles, and tactical vests, and, then, upon
    entering the apartment, those officers prohibited the
    defendant from leaving or otherwise moving about the
    apartment. In such circumstances, it was reasonable
    for the defendant to perceive such an imposing display
    of authority as a clear indication that the police intended
    to assume and maintain full control over her and her
    daughters. See, e.g., Moss v. 
    State, supra
    , 675 (‘‘[in]
    conclud[ing] that [the defendant] was in custody during
    the police questioning’’ at his home during execution
    of search warrant, court ‘‘emphasize[d] the fact that
    the police entered [his] residence at gunpoint and con-
    trolled his movements and [those of] the other residents
    at least at the beginning of the search’’).
    Another factor that supports a finding of custody is
    the number of law enforcement personnel involved in
    the execution of the search warrant. A total of seven
    officers participated in the search of the defendant’s
    residence, a police presence that is particularly signifi-
    cant in view of the fact that the defendant’s apartment
    consisted of only four rooms. As the Ninth Circuit Court
    of Appeals has stated, ‘‘the presence of a large number
    of visibly armed law enforcement officers goes a long
    way [toward] making the suspect’s home a police-domi-
    nated atmosphere.’’ United States v. 
    Craighead, supra
    ,
    
    539 F.3d 1085
    ; see also United States v. Revels, 
    510 F.3d 1269
    , 1270, 1277 (10th Cir. 2007) (custodial interroga-
    tion of defendant occurred when seven officers from
    two different agencies entered his home to execute
    search warrant); United States v. Mittel-Carey, 
    493 F.3d 36
    , 39–40 (1st Cir. 2007) (defendant was in custody
    when eight officers executed search warrant in his
    home). In addition, there is an increased likelihood that
    a reasonable person in the defendant’s position would
    have been intimidated by the considerable police pres-
    ence because many, if not all, of the officers were in
    the living room with the defendant when Hicks ques-
    tioned her.
    The fact that the police exercised complete control
    over the defendant and her surroundings before, during
    and after Hicks’ questioning of her is a fourth consider-
    ation that tends to establish custody. Immediately upon
    entering the apartment, the officers ordered the defen-
    dant and her three daughters to go to the living room,
    where they were required to remain, under guard.
    ‘‘[T]he likely effect on a suspect of being placed under
    guard during questioning, or told to remain in the sight
    of interrogating officials, is to associate these restraints
    with a formal arrest.’’ United States v. 
    Griffin, supra
    ,
    
    922 F.2d 1350
    –51. This exercise of total control over
    the defendant stands in stark contrast to the far more
    relaxed environment that is a hallmark of interrogations
    in a suspect’s home that have been found to be noncus-
    todial. For example, in State v. 
    Read, supra
    , 132 Conn.
    App. 17, the Appellate Court concluded that the defen-
    dant was not in custody during the execution of a search
    warrant when, after being told that he was ‘‘free to come
    and go as [he] pleased,’’ he strolled, unaccompanied,
    around the property and, in fact, repeatedly left the
    searched premises to visit a nearby general store. (Inter-
    nal quotation marks omitted.) 
    Id., 21. In
    the present
    case, the defendant was confined to a couch in the
    living room, where she was kept under constant police
    observation and prohibited from moving about the
    apartment.
    Finally, the police never provided the defendant with
    an explanation of the nature, purpose, or likely duration
    of her detention. At the very least, the circumstances
    of the entry and search by the police were sufficiently
    coercive and disquieting that the defendant reasonably
    would have been concerned about how long she would
    be detained and how she and her daughters otherwise
    would be treated by the police. Indeed, the fact that
    the police told the defendant nothing about whether
    or when she might be released could have led her to
    presume that her situation was not likely to change
    anytime soon.14
    In this and several other important respects, the cir-
    cumstances in which the defendant found herself are
    vastly different from those of other lawful seizures that
    have been deemed to be noncustodial for purposes of
    Miranda, the most commonplace of which is an ordi-
    nary traffic stop.15 ‘‘Two features of an ordinary traffic
    stop mitigate the danger that a person questioned will
    be induced to speak [when] he would not otherwise do
    so freely . . . . First, [the] detention of a motorist pur-
    suant to a traffic stop is presumptively temporary and
    brief. . . . [Therefore, a] motorist’s expectations,
    when he sees a [police cruiser’s] light[s] flashing behind
    him, are that he will be obliged to spend a short period of
    time answering questions and waiting while the officer
    checks his license and registration, that he may then
    be given a citation, but that in the end he most likely
    will be allowed to continue on his way. . . .
    ‘‘Second, circumstances associated with the typical
    traffic stop are not such that the motorist feels com-
    pletely at the mercy of the police. . . . [Specifically]
    the typical traffic stop is public, at least to some degree.
    Passersby, on foot or in other cars, witness the interac-
    tion of [the] officer and motorist. This exposure to pub-
    lic view both reduces the ability of an unscrupulous
    policeman to use illegitimate means to elicit self-incrim-
    inating statements and diminishes the motorist’s fear
    that, if he does not cooperate, he will be subjected to
    abuse. The fact that the detained motorist typically is
    confronted by only one or at most two policemen fur-
    ther mutes his sense of vulnerability.’’ (Citations omit-
    ted; footnotes omitted; internal quotation marks omit-
    ted.) Berkemer v. 
    McCarty, supra
    , 
    468 U.S. 437
    –38.
    None of these mitigating considerations factored into
    the circumstances surrounding the detention of the
    defendant in the present case. The defendant had no
    way of knowing that she was being detained only tempo-
    rarily, and, consequently, she had no reason to know
    or expect that her status as a detainee would end upon
    the conclusion of the search. Moreover, seven armed
    officers participated in the search, which took place
    in a setting free from public view, where the police
    exercised complete control over the defendant and her
    daughters. Under the circumstances, there simply is no
    reason why she would not have felt extremely vulnera-
    ble and ‘‘completely at the mercy of the police.’’ 
    Id., 438. The
    officers easily could have told the defendant
    that she was not under arrest and that she was being
    detained merely for the duration of the search. Although
    not necessarily determinative of the custody issue,
    ‘‘[t]he most obvious and effective means of demonstra-
    ting that a suspect has not been taken into custody
    . . . is for the police to inform the suspect that an
    arrest is not being made and that the suspect may termi-
    nate the interview at will.’’16 (Citation omitted; internal
    quotation marks omitted.) United States v. 
    Griffin, supra
    , 
    922 F.2d 1349
    ; see also Howes v. 
    Fields, supra
    ,
    
    132 S. Ct. 1193
    (fact that police told suspect that he
    was free to leave and terminate interview was ‘‘[m]ost
    important’’ consideration for purposes of custody deter-
    mination under Miranda); State v. Greenfield, 
    228 Conn. 62
    , 71 n.10, 
    634 A.2d 879
    (1993) (‘‘[o]ften, an
    important factor distinguishing a consensual encounter
    from a seizure is whether the police expressly informed
    the [suspect] that he was free to leave at the outset of
    the interview’’); cf. United States v. 
    Craighead, supra
    ,
    
    539 F.3d 1087
    (‘‘[i]f a law enforcement officer informs
    the suspect that he is not under arrest, that statements
    are voluntary, and that he is free to leave at any time,
    this communication greatly reduces the chance that a
    suspect will reasonably believe he is in custody’’).
    When, however, a detained suspect is not so informed
    but, instead, is kept in the dark about the purpose and
    duration of the detention, he is far more likely to view
    his seizure by the police as the functional equivalent
    of an arrest. See Moss v. 
    State, supra
    , 
    823 P.2d 674
    (‘‘[e]specially when force is used or a display of weap-
    ons is made, a person who has been [detained] and
    placed in the effective custody—albeit temporary—of
    the police . . . will certainly understand that he has
    been placed in custody, but he may not understand the
    temporary nature of the seizure unless it is explained’’).
    Even if a suspect is merely confused or unclear as to
    her custodial status, she may feel compelled to submit
    to police questioning for fear that her refusal to cooper-
    ate will reduce her chances for release or other favor-
    able treatment. See, e.g., Illinois v. Perkins, 
    496 U.S. 292
    , 296–97, 
    110 S. Ct. 2394
    , 
    110 L. Ed. 2d 243
    (1990)
    (suspect questioned by law enforcement officers under
    coercive circumstances may ‘‘feel compelled to speak
    by the fear of reprisal for remaining silent or in the
    hope of more lenient treatment should he [cooperate]’’).
    It is true that a number of factors militate against a
    finding that the defendant in the present case was in
    custody. In particular, she was not handcuffed, the
    police did not threaten her or tell her that she was
    under arrest, and the questioning, which was brief, took
    place in her own home. For the following reasons, how-
    ever, we are not persuaded that these factors outweigh
    the coercive features of the defendant’s detention.
    Perhaps the most significant consideration favoring
    the state’s claim that the defendant was not in custody
    is the fact that the questioning took place in the familiar
    surroundings of the defendant’s apartment. We recog-
    nize that an encounter with police is generally less likely
    to be custodial when it occurs in a suspect’s home. See,
    e.g., Miranda v. 
    Arizona, supra
    , 
    384 U.S. 449
    –50 (‘‘[the
    suspect] is more keenly aware of his rights and more
    reluctant to tell of his indiscretions or criminal behavior
    within the walls of his home’’ [internal quotation marks
    omitted]); United States v. 
    Hashime, supra
    , 
    734 F.3d 284
    (‘‘courts are generally less likely to characterize
    . . . interrogations in familiar settings like the home
    [as custodial]’’). ‘‘Miranda, however, does not allow
    for a simple in-home [versus] out-of-home dichotomic
    analysis.’’ United States v. Cavazos, 
    668 F.3d 190
    , 194
    (5th Cir. 2012). ‘‘More important than the familiarity of
    the surroundings [in his home] where [the defendant]
    was being [questioned] is the degree to which the police
    dominated the scene.’’ Sprosty v. Buchler, 
    79 F.3d 635
    ,
    641 (7th Cir.), cert. denied, 
    519 U.S. 854
    , 
    117 S. Ct. 150
    ,
    
    136 L. Ed. 2d 95
    (1996); see also United States v. 
    Griffin, supra
    , 
    922 F.2d 1354
    –55 (‘‘[q]uestioning [that] occurs
    in the suspect’s own home may provide a margin of
    comfort, but . . . the setting of the interrogation is not
    so important to the inquiry as the question of police
    domination of that setting’’). Consequently, ‘‘when
    applying Miranda to the task of sorting a [noncustodial]
    in-home interrogation from a custodial one, [a court
    must consider] the extent to which the circumstances
    of the interrogation turned the otherwise comfortable
    and familiar surroundings of the home into a police-
    dominated atmosphere.’’ (Internal quotation marks
    omitted.) United States v. 
    Craighead, supra
    , 
    539 F.3d 1083
    .
    When a large contingent of armed police officers
    forcibly enter a suspect’s residence under the official
    authority of a search warrant and detain the suspect
    during the search, that residence is no longer a bastion
    of privacy and security; rather, it has been transformed,
    albeit lawfully, into a hub of law enforcement activity
    directed against the suspect. Consequently, ‘‘it is not
    difficult to envision that a suspect’s sense of captivity
    can actually be intensified by the intrusive and intim-
    idating environment created when agents of the law
    take control of a person’s private residence.’’ United
    States v. 
    Griffin, supra
    , 1355 n.15. ‘‘[A] reasonable per-
    son interrogated inside his own home may [not under-
    stand that] he is truly free to terminate the interrogation
    if his home is crawling with law enforcement agents
    conducting a warrant-approved search. He may not feel
    that he can successfully terminate the interrogation if
    he knows that he cannot empty his home of his interro-
    gators until they have completed their search.’’ (Internal
    quotation marks omitted.) United States v. 
    Craighead, supra
    , 1083. We therefore agree with the defendant
    that the facts and circumstances surrounding the police
    encounter in the present case ‘‘belie any conclusion
    that [the defendant’s] home, [at the time] of the ques-
    tioning at issue, was the traditional comfortable envi-
    ronment that . . . normally would [be] consider[ed] a
    neutral location for questioning.’’ United States v. Rev-
    
    els, supra
    , 
    510 F.3d 1275
    –76.
    The state also argues that, because the defendant
    was not handcuffed, she reasonably could not have
    believed that she was in custody to the degree associ-
    ated with a formal arrest. As the state maintains,
    ‘‘[h]andcuffs are generally recognized as a hallmark of
    a formal arrest.’’ United States v. Newton, 
    369 F.3d 659
    ,
    676 (2d Cir.), cert. denied, 
    543 U.S. 947
    , 
    125 S. Ct. 371
    ,
    
    160 L. Ed. 2d 262
    (2004); see also United States v.
    Maguire, 
    359 F.3d 71
    , 79 (1st Cir. 2004) (‘‘the use of
    handcuffs . . . [is] one of the most recognizable indi-
    cia of traditional arrest’’ [internal quotation marks omit-
    ted]). As we previously have explained, however, no
    one factor in a custody analysis is outcome determina-
    tive. See Howes v. 
    Fields, supra
    , 
    132 S. Ct. 1189
    .
    Although the defendant was not handcuffed, the highly
    coercive atmosphere of the police entry and search,
    including the large and intimidating police presence,
    the severe limitation placed on the defendant’s freedom
    of movement, and the failure of the police to explain
    to her the temporary nature of her detention lead us
    to conclude that the defendant reasonably would have
    believed that she was in custody even though the police
    did not use handcuffs.
    In further support of its argument that the defendant
    was not in custody, the state also relies on the facts
    that the police did not tell her that she was under arrest,
    they did not threaten her, and the questioning was brief.
    Although the police never advised the defendant that
    she was under arrest, they also never told her that
    she was not under arrest, and their conduct—the same
    conduct that caused the defendant, reasonably and cor-
    rectly, to believe that she was not free to leave—con-
    veyed a clear message of complete, unfettered and
    temporally indefinite police control. The police also
    did not threaten the defendant, but the circumstances
    surrounding the search were themselves threatening
    and intimidating. Similarly, although the questioning
    itself was neither prolonged nor intimidating, it was
    the coercive environment in which Hicks queried the
    defendant that reasonably caused her to believe that
    she was in custody. We therefore reject the state’s con-
    tention that the several noncoercive elements of Hicks’
    questioning obviated the need for Miranda warnings.17
    Although we conclude that the defendant’s constitu-
    tional rights were violated when Hicks questioned the
    defendant without first issuing Miranda warnings, it
    bears emphasis that her detention during the execution
    of the search warrant was reasonable for purposes of
    the fourth amendment. As the United States Supreme
    Court held in Michigan v. 
    Summers, supra
    , 
    452 U.S. 692
    ,
    ‘‘for [f]ourth [a]mendment purposes . . . a warrant to
    search for contraband founded on probable cause
    implicitly carries with it the limited authority to detain
    the occupants of the premises while a proper search
    is conducted.’’ (Footnote omitted.) 
    Id., 705; see
    also 
    id., 702 (explaining
    that interests of officer safety, preven-
    tion of flight, and preservation of evidence are served
    by permitting police to detain occupant during execu-
    tion of search warrant for his residence). It also is
    settled, however, that ‘‘whether an individual detained
    during the execution of a search warrant has been . . .
    seized for [f]ourth [a]mendment purposes and whether
    that individual is ‘in custody’ for Miranda purposes are
    two different issues’’; United States v. Kim, 
    292 F.3d 969
    , 976 (9th Cir. 2002); because ‘‘[c]ustody for Miranda
    purposes requires a greater restraint on freedom than
    seizure under the [f]ourth [a]mendment.’’18 United
    States v. 
    Cavazos, supra
    , 
    668 F.3d 193
    ; see also United
    States v. 
    Newton, supra
    , 
    369 F.3d 673
    (‘‘[the] court . . .
    has specifically rejected [f]ourth [a]mendment reason-
    ableness as the standard for resolving Miranda custody
    challenges’’). Thus, ‘‘[a]lthough some detentions not ris-
    ing to the level of a formal arrest may be reasonable
    within the meaning of the [f]ourth [a]mendment, those
    same detentions may nonetheless create the custodial
    situation in which Miranda was designed to operate.’’
    United States v. Rev
    els, supra
    , 
    510 F.3d 1274
    .
    Furthermore, the fact that the fourth amendment per-
    mits the police to detain a suspect while executing a
    search warrant in her home does not alter the coercive
    effect of that detention, especially when the suspect is
    not informed that the detention is temporary. ‘‘[I]n many
    cases, when law enforcement agents conduct an in-
    home interrogation while conducting a lawful search
    of the home, physical control of the suspect will be
    necessary to preserve evidence and [to] protect the
    safety of the agents. The fact that these precautions
    may be necessary to the success of the lawful search
    does not lessen their tendency to make a reasonable
    person believe he is in custody.’’ United States v. Craig-
    
    head, supra
    , 
    539 F.3d 1086
    . We also agree that, ‘‘[i]f the
    . . . [officers’] actions were necessary for evidence
    preservation and officer safety, then [Hicks] could have
    chosen to postpone the interrogation until a [noncusto-
    dial] moment . . . or to [administer Miranda warn-
    ings]. Either step would have protected both the
    defendant’s constitutional rights and the officers’ legiti-
    mate law enforcement needs.’’ United States v. Mittel-
    
    Carey, supra
    , 
    493 F.3d 40
    .
    We note, finally, that the state relies on language in
    Michigan v. 
    Summers, supra
    , 
    452 U.S. 692
    , to support
    its contention that Hicks’ questioning of the defendant
    was noncustodial. In Summers, the court, in explaining
    why the police did not violate the fourth amendment
    when they detained the respondent, George Summers,
    during the execution of a search warrant at his home,
    observed that Summers’ detention in that case was
    ‘‘substantially less intrusive’’ than an arrest. (Internal
    quotation marks omitted.) 
    Id., 702. In
    the state’s view,
    the Appellate Court correctly concluded that this com-
    ment by the court in Summers establishes that a suspect
    is ordinarily not in custody when she is detained inci-
    dent to the execution of a search warrant. See State v.
    
    Mangual, supra
    , 
    129 Conn. App. 648
    . The state also
    agrees with the Appellate Court that the trial court’s
    determination on the issue of custody must be upheld
    because the trial court made no factual findings to sup-
    port the conclusion that the defendant was subject to
    any greater limitations on her freedom of movement
    than those normally occurring when a search warrant
    is executed. See 
    id. We disagree
    with this analysis for several reasons.
    First, Summers is a fourth amendment case that had
    nothing to do with the question of when a suspect is
    in custody for purposes of Miranda. Second, because
    the court’s decision in Summers says very little about
    the circumstances surrounding Summers’ detention, we
    cannot discern whether and, if so, to what extent, the
    court considered those circumstances in concluding
    that the restraint on Summers’ liberty was less than
    that of a formal arrest. Finally, as we have explained,
    courts invariably have looked to the facts of the particu-
    lar case to determine whether, in light of all relevant
    circumstances, the suspect detained in his home was
    in custody for purposes of Miranda. Indeed, the United
    States Supreme Court consistently has emphasized that
    the fact specific issue of custody must be decided on
    the basis of the court’s consideration of the totality of
    the circumstances surrounding the interrogation. See,
    e.g., J. D. B. v. North Carolina,     U.S.     , 
    131 S. Ct. 2394
    , 2402, 
    180 L. Ed. 2d 310
    (2011); Howes v. 
    Fields, supra
    , 
    132 S. Ct. 1189
    ; Thompson v. 
    Keohane, supra
    ,
    
    516 U.S. 112
    . Accordingly, we reject any suggestion
    that the defendant was not in custody for purposes of
    Miranda merely because she was lawfully detained
    inside her apartment during the execution of the
    search warrant.
    II
    Having determined that the trial court and the Appel-
    late Court improperly concluded that the police were
    not required to advise the defendant of her Miranda
    rights prior to eliciting statements from her, we next
    must address the state’s claim that the admission of
    those statements into evidence was harmless beyond
    a reasonable doubt. For the reasons that follow, we are
    not persuaded that the state can meet that demand-
    ing standard.
    The state claims that its reliance on the defendant’s
    statements had no bearing on the outcome of the trial
    because the other evidence of guilt was compelling.
    The defendant maintains that, although the heroin was
    discovered in the hairspray can found in her bedroom,
    her statements to Hicks constituted the only direct evi-
    dence that she knew that the heroin was in the hairspray
    can, and, further, the indirect or circumstantial evi-
    dence of her knowledge was not strong.
    The following additional facts were adduced at trial
    and are relevant to this issue. In January and February,
    2008, the defendant and her children resided with Jesus
    Ortiz, who shared a bedroom with the defendant, and
    Dionices Flores, known as ‘‘Bebo,’’ who slept in a sepa-
    rate room in the apartment. The confidential informants
    who had participated in controlled purchases of heroin
    from inside the apartment reported buying the drugs
    from Hispanic males only, and one such informant spe-
    cifically identified a Hispanic male named ‘‘Bebo’’ as the
    person from whom he had purchased heroin. Another
    informant, however, told police that he had witnessed
    a woman named ‘‘Ada’’ sell heroin, and that he believed
    that she was responsible for the drug sales in the
    apartment.19
    During the search of the bedroom that the defendant
    and Ortiz had shared, investigating officers discovered
    the following items in addition to the hairspray can
    containing heroin: (1) separate pieces of mail addressed
    to the defendant, Ortiz and Flores; (2) a police scanner;
    (3) state social services cards for Jeffrey Moctezuma
    and Dionices Flores-Garcia; (4) more than $400 in cash;
    (5) a cell phone; and (6) two notebooks containing
    names, addresses and numbers. At some point during
    the search, Flores arrived, and the officers arrested him
    for possession of narcotics. The police also arrested
    the defendant and found her in possession of a cell
    phone and two $20 bills that had been used by one of
    the confidential informants to purchase heroin from
    inside the apartment.20
    At trial, the defendant testified that the can of hairsp-
    ray and the drugs found therein belonged to Flores,
    who sometimes would keep his belongings in her room.
    The defendant also testified that she did not know who
    owned the police scanner or the notebook, and that
    the notations in the notebook were not in her handwrit-
    ing. She further stated that Ortiz owned one of the cell
    phones found by the police and that the other belonged
    to one of her daughters. In addition, the defendant
    claimed that the money seized from her bedroom came
    from several legitimate sources, in particular, wages
    that she had earned from her job at a restaurant, pro-
    ceeds from workers’ compensation and personal injury
    claims, and Flores’ share of the rent and living expenses,
    which he paid to the defendant in cash every two weeks.
    One of the defendant’s daughters also testified at trial
    and corroborated certain aspects of the defendant’s
    testimony, including the defendant’s contention that the
    hairspray can was owned by Flores. Finally, during
    closing argument to the jury, the state twice under-
    scored the significance of the defendant’s response to
    Hicks’ questions.
    ‘‘If statements taken in violation of Miranda are
    admitted into evidence during a trial, their admission
    must be reviewed in light of the harmless error doctrine.
    . . . [W]hether an error is harmful depends on its
    impact on the trier of fact and the result of the case.
    . . . This court has held in a number of cases that when
    there is independent overwhelming evidence of guilt,
    a constitutional error would be rendered harmless
    beyond a reasonable doubt. . . . When an [evidentiary]
    impropriety is of constitutional proportions, the state
    bears the burden of proving that the error was harmless
    beyond a reasonable doubt. . . . [W]e must examine
    the impact of the evidence on the trier of fact and the
    result of the trial. . . . If the evidence may have had
    a tendency to influence the judgment of the jury, it
    cannot be considered harmless. . . . That determina-
    tion must be made in light of the entire record [including
    the strength of the state’s case without the evidence
    admitted in error].’’ (Citations omitted; internal quota-
    tion marks omitted.) State v. Mitchell, 
    296 Conn. 449
    ,
    459–60, 
    996 A.2d 251
    (2010).
    The defendant was convicted of possessing narcotics
    with the intent to sell. ‘‘[T]o prove illegal possession of
    a narcotic substance, it is necessary to establish that
    the defendant knew the character of the substance,
    knew of its presence and exercised dominion and con-
    trol over it. . . . [When] . . . the [narcotics are] not
    found on the defendant’s person, the state must proceed
    on the theory of constructive possession, that is, posses-
    sion without direct physical contact. . . . [When] the
    defendant is not in exclusive possession of the premises
    where the narcotics are found, it may not be inferred
    that [the defendant] knew of the presence of the narcot-
    ics and had control of them, unless there are other
    incriminating statements or circumstances tending to
    buttress such an inference.’’ (Internal quotation marks
    omitted.) State v. Bruno, 
    293 Conn. 127
    , 136, 
    975 A.2d 1253
    (2009).
    We agree with the defendant that the state cannot
    demonstrate beyond a reasonable doubt that the
    improper admission of the defendant’s statements was
    harmless because those statements were the only direct
    and definitive evidence of the defendant’s knowledge
    that there was heroin in her bedroom. Evidence
    adduced at trial, if credited, tended to establish that
    Flores, who resided in the apartment with the defen-
    dant, exercised exclusive possession of and control
    over the drugs. For example, the defendant testified that
    the hairspray can belonged to Flores. The defendant and
    her daughter also testified that Flores sometimes left
    his belongings in the defendant’s room. This testimony
    was corroborated by the fact that Flores’ mail and his
    state social services card were found in the defendant’s
    bedroom. From the search warrant affidavit, the jury
    was aware that a confidential informant told the police
    that he had bought heroin from a person in the apart-
    ment named ‘‘Bebo,’’ Flores’ nickname, who matched
    Flores’ description. In addition, the defendant testified
    that Flores paid her in cash for his share of the rent
    and living expenses, thereby providing a plausible
    explanation for why she was found to possess the two
    $20 bills that were used by one of the confidential infor-
    mants to purchase drugs from a Hispanic male, presum-
    ably Flores, inside the apartment. Although we acknow-
    ledge that, according to the search warrant affidavit that
    had been admitted into evidence, one of the confidential
    informants reported seeing a woman in the apartment
    named ‘‘Ada’’ selling heroin, this hearsay statement was
    not subject to cross-examination and can hardly be
    characterized as powerful evidence of the defendant’s
    guilt, especially because none of the informants actually
    purchased heroin from the defendant. Finally, the rela-
    tive importance of the defendant’s statements to the
    state’s case is reflected in the fact that the state twice
    referred to the statements during closing arguments.
    Thus, although Hicks’ testimony about the defen-
    dant’s statements constituted overwhelming evidence
    of the defendant’s knowledge that heroin was concealed
    in the hairspray can found in her bedroom, in the
    absence of those statements, it would not have been
    irrational or far-fetched for the jury to harbor a reason-
    able doubt with respect to that knowledge requirement.
    We therefore cannot say that the defendant’s statements
    had no tendency to influence the judgment of the jury
    with respect to its resolution of the case. Accordingly,
    the improper admission into evidence of those state-
    ments was not harmless beyond a reasonable doubt.
    The judgment of the Appellate Court is reversed and
    the case is remanded to that court with direction to
    reverse the judgment of the trial court and to remand
    the case to that court for a new trial.
    In this opinion the other justices concurred.

    Under Miranda, if police question a suspect who is in custody, any
    statements made by the suspect in response to the questioning will be
    suppressed unless, prior to the questioning, the suspect is advised that he
    ‘‘has a right to remain silent, that any statement he does make may be used
    as evidence against him, and that he has a right to the presence of an
    attorney, either retained or appointed.’’ Miranda v. 
    Arizona, supra
    , 
    384 U.S. 444
    . The fundamental purpose of Miranda warnings, which, as the United
    States Supreme Court has reaffirmed, are constitutionally mandated; see
    Dickerson v. United States, 
    530 U.S. 428
    , 432, 444, 
    120 S. Ct. 2326
    , 147 L.
    Ed. 2d 405 (2000); is to ensure ‘‘that [an] individual [subjected to custodial
    police interrogation] is accorded his privilege under the [f]ifth [a]mendment
    to the [United States] [c]onstitution not to be compelled to incriminate
    himself.’’ Miranda v. 
    Arizona, supra
    , 439. The fifth amendment privilege
    against self-incrimination is made applicable to the states through the due
    process clause of the fourteenth amendment to the United States constitu-
    tion. See, e.g., Malloy v. Hogan, 
    378 U.S. 1
    , 6, 
    84 S. Ct. 1489
    , 
    12 L. Ed. 2d
    653 (1964). The ‘‘[f]ailure to administer Miranda warnings creates a
    presumption of compulsion’’ that is ‘‘irrebuttable for purposes of the prosecu-
    tion’s case in chief . . . .’’ Oregon v. Elstad,

    , 307, 
    105 S. Ct. 1285
    , 
    84 L. Ed. 2d 222
    (1985).

    The defendant’s daughters were nineteen, sixteen and thirteen years of
    age, respectively, when the police executed the search warrant.
    3
    The record does not indicate how long it took the police to complete
    the search after discovering the heroin in the defendant’s bedroom. We also
    note that all seven officers participated in the execution of the search
    warrant. Some of the officers were in police uniform; the other officers
    wore tactical vests identifying them as members of the department.
    4
    The opinion of the Appellate Court also sets forth the following testimony
    that the defendant adduced in support of her motion to suppress. ‘‘[T]he
    defendant called [her sixteen year old daughter, who was present when the
    search was conducted]. [The daughter] testified that during the execution
    of the search warrant, the officers denied her requests to use the [bathroom]
    and to have the defendant sit in the living room area with the other occupants.
    In addition, she claimed that the officers removed the defendant’s pit bull
    dog from the apartment and in doing so ‘put [a] gun in the dog’s face . . . .’
    Finally, [the daughter] testified that she did not feel free to leave the apart-
    ment while the officers were executing the search warrant.
    ‘‘The defendant offered the following [additional] testimony in support
    of her motion. When the police entered the apartment, they were carrying
    rifles and did not inform her that they had a search and seizure warrant.
    She asked to sit next to her daughters and to use the bathroom, but the
    officers denied both requests. She admitted that the officers did not place
    her in handcuffs but testified that she did not feel free to leave the apartment
    or to ask the officers to leave.’’ State v. 
    Mangual, supra
    , 
    129 Conn. App. 643
    . The trial court made no reference to this testimony, which the state
    disputed in certain material respects. We therefore do not consider it for
    purposes of this appeal.
    5
    The defendant sought to suppress ‘‘any response’’ that she allegedly
    gave to Hicks as a result of the questioning. This includes both her verbal
    acknowledgment that there were drugs in the apartment as well as her
    conduct in leading the police to the heroin secreted in the hairspray can in
    the bedroom. For the reasons set forth hereinafter, the defendant is entitled
    to suppression of that expressive conduct, both verbal and nonverbal, in
    response to Hicks’ questioning. See, e.g., Pennsylvania v. Muniz, 
    496 U.S. 582
    , 589, 
    110 S. Ct. 2638
    , 
    110 L. Ed. 2d 528
    (1990) (fifth amendment protects
    individuals from compulsion to provide state with testimonial communica-
    tions that ‘‘explicitly or implicitly . . . relate a factual assertion or disclose
    information’’ [internal quotation marks omitted]); People v. Hoffman, 
    84 Ill. 2d
    480, 490, 
    419 N.E.2d 1145
    (1981) (‘‘the act of leading [an] officer to the
    place where the pistol was found was conduct of a testimonial nature and,
    in the absence of Miranda warnings, testimony concerning that fact should
    have been suppressed’’); State v. Wethered, 
    110 Wash. 2d 466
    , 471, 
    755 P.2d 797
    (1988) (‘‘[when] a police officer’s questioning or requests induce a
    suspect to hand over or reveal the location of incriminating evidence, such
    [a] nonverbal act may be testimonial in nature; the act should be suppressed
    if done while in custody in the absence of Miranda warnings’’). All references
    in this opinion to the defendant’s statements include both her verbal and
    nonverbal conduct.
    We also note that the defendant asserts, in passing, that the police likely
    would not have discovered the heroin hidden in the hairspray can if the
    defendant had not alerted police to its existence. The defendant, however,
    has raised no claim that the heroin itself should be suppressed as a fruit
    of the Miranda violation. Indeed, a statement that is obtained in violation of
    Miranda does not require suppression of the physical fruits of the suspect’s
    unwarned but otherwise voluntary statements. See, e.g., United States v.
    Patane, 
    542 U.S. 630
    , 636–37, 
    124 S. Ct. 2620
    , 
    159 L. Ed. 2d 667
    (2004);
    United States v. Parker, 
    549 F.3d 5
    , 10 (1st Cir. 2008), cert. denied, 
    556 U.S. 1160
    , 
    129 S. Ct. 1688
    , 
    173 L. Ed. 2d 1050
    (2009).
    6
    The defendant also claimed that the trial court violated her constitutional
    right to present a defense by excluding evidence that another resident of
    the apartment, Dionices Flores, known as ‘‘Bebo,’’ had pleaded guilty to
    possession of the heroin discovered in her bedroom. State v. 
    Mangual, supra
    , 
    129 Conn. App. 649
    . The Appellate Court determined that the record
    was inadequate for review of the claim and therefore declined to consider
    it. 
    Id. That claim
    is not at issue in the present appeal.
    7
    The defendant does not assert that her rights under article first, § 8, of
    the Connecticut constitution were violated. Rather, her claim is limited to
    the protections afforded under the fifth and fourteenth amendments to the
    United States constitution. Accordingly, our analysis is also limited to those
    federal constitutional provisions.
    8
    Thus, even ‘‘patently voluntary statements taken in violation of Miranda
    must be excluded from the prosecution’s case . . . .’’ (Emphasis omitted.)
    Oregon v. Elstad, 
    470 U.S. 298
    , 307, 
    105 S. Ct. 1285
    , 
    84 L. Ed. 2d 222
    (1985).
    9
    The defendant bears the burden of establishing custodial interrogation.
    E.g., State v. Jackson, 
    304 Conn. 383
    , 417, 
    40 A.3d 290
    (2012).
    10
    We note that, at trial, the defendant testified that she had not made any
    statements to Hicks. In view of the fact that the state takes a contrary
    position, the defendant nevertheless is entitled to seek to have Hicks’ testi-
    mony suppressed because the jury would be free to consider that testimony
    unless, of course, it is excluded under Miranda. To be sure, Miranda is
    not a license to commit perjury, and statements obtained in violation of
    Miranda, if not the product of improper police coercion, are admissible for
    impeachment purposes. See, e.g., Harris v. New York, 
    401 U.S. 222
    , 225–26,
    
    91 S. Ct. 643
    , 
    28 L. Ed. 2d 1
    (1971); State v. Burge, 
    195 Conn. 232
    , 250–51,
    
    487 A.2d 532
    (1985). The issue in the present case, however, is whether the
    trial court properly permitted the state to use the defendant’s statements
    in its case-in-chief.
    11
    Thus, in Berkemer, the court concluded that a motorist who is subject
    to an ordinary traffic stop generally will not be deemed to be in custody
    for purposes of Miranda even though ‘‘few motorists would feel free either
    to disobey a directive to pull over or to leave the scene of a traffic stop
    without being told they might do so.’’ Berkemer v. 
    McCarty, supra
    , 
    468 U.S. 436
    . Although the court acknowledged that even a routine traffic stop
    ‘‘significantly curtails the ‘freedom of action’ of the driver and the passen-
    gers’’; id.; it explained that, because the brief detention typically associated
    with such stops, like the brief detention for investigative purposes permitted
    under Terry v. Ohio, 
    392 U.S. 1
    , 30, 
    88 S. Ct. 1868
    , 
    20 L. Ed. 2d 889
    (1968)
    (if police officer has reasonable and articulable suspicion that criminal
    activity may be afoot, officer may briefly stop suspicious person and make
    reasonable inquiries aimed at confirming or dispelling his suspicions), is
    ‘‘comparatively nonthreatening’’ and ‘‘noncoercive,’’ Miranda warnings are
    not required for ‘‘detentions of [that] sort’’ unless the police engage in
    conduct further limiting the freedom of action of the person detained to a
    degree akin to that of a formal arrest. Berkemer v. 
    McCarty, supra
    , 440.
    12
    Thus, ‘‘a free-to-leave inquiry reveals only whether the person questioned
    was seized. . . . Because seizure is a necessary prerequisite to Miranda
    . . . it makes sense for a court to begin any custody analysis by asking
    whether a reasonable person would have thought he was free to leave the
    police encounter at issue. If the answer is yes, the Miranda inquiry is at
    an end; the challenged interrogation did not require advice of rights. On the
    other hand, if a reasonable person would not have thought [that he was]
    free to leave, additional analysis is required because, as Berkemer v.
    McCarty, [supra, 
    468 U.S. 439
    –40] instructs, not every seizure constitutes
    custody for purposes of Miranda. . . . In such cases, a court must ask
    whether, in addition to not feeling free to leave, a reasonable person would
    have understood his freedom of action to have been curtailed to a degree
    associated with formal arrest. . . . Only if the answer to this second ques-
    tion is yes was the person in custody for practical purposes . . . and entitled
    to the full panoply of protections prescribed by Miranda. Berkemer v.
    McCarty, [supra, 440].’’ (Citations omitted; internal quotation marks omit-
    ted.) United States v. Newton, 
    369 F.3d 659
    , 672 (2d Cir.), cert. denied,

    125 S. Ct. 371
    , 
    160 L. Ed. 2d 262
    (2004).
    We note that, although this court frequently has defined custody for
    purposes of Miranda as a restraint on the suspect’s freedom of movement
    to a degree associated with a formal arrest, we have not always clearly
    distinguished that ultimate inquiry from the threshold determination of
    whether a reasonable person in the suspect’s position would feel free to
    terminate the questioning and leave. Specifically, we sometimes have
    appeared to conflate those two distinct inquiries by suggesting that a suspect
    who demonstrates that she reasonably believed that she was not free to
    leave necessarily satisfies the second, ultimate step in the analytic process,
    namely, that the restraint on her freedom of movement was tantamount to
    that of a formal arrest. See, e.g., In re Kevin K., 
    299 Conn. 107
    , 127, 128, 
    7 A.3d 898
    (2010) (explaining that, ‘‘in determining whether Miranda rights
    are required, the only relevant inquiry is whether a reasonable person in
    the defendant’s position would believe that he or she was in police custody
    of the degree associated with a formal arrest,’’ but characterizing ‘‘[t]he
    ultimate determination of whether a defendant was subjected to a custodial
    interrogation’’ as depending on whether ‘‘a reasonable person [would] have
    felt he or she was not at liberty to terminate the interrogation and [to] leave’’
    [internal quotation marks omitted]); State v. Kirby, 
    280 Conn. 361
    , 393, 394,
    
    908 A.2d 506
    (2006) (same). Indeed, on occasion, we have recited the test
    for custody solely in terms of the suspect’s reasonable belief that he was
    not free to leave. See, e.g., State v. Mullins, 
    288 Conn. 345
    , 363, 
    952 A.2d 784
    (2008) (stating that, in determining whether suspect is in custody for
    purposes of Miranda, ‘‘[t]he trial court first makes a factual determination
    of the circumstances surrounding the alleged interrogation and then applies
    those facts to an objective test as to whether a reasonable person would
    have felt that he or she was not at liberty to leave’’); State v. Canales, 
    281 Conn. 572

    288 Conn. 836
    , 844 n.5, 
    955 A.2d 43
    (2008) (‘‘the test for determining custody
    for Miranda purposes is the same in all material respects as the test that
    this court uses to determine whether an individual [has been] seized, that
    is, whether a reasonable person in the defendant’s position would have
    believed that he was not free to leave’’). To the extent that these cases have
    failed to recognize the distinction between the two separate steps that
    comprise the test for determining custody for purposes of Miranda, we
    take this opportunity to underscore the constitutional significance of that dis-
    tinction.
    13
    We emphasize that the test for whether an interrogation was custodial is
    an objective one. ‘‘[T]he subjective views harbored by either the interrogating
    officers or the person being questioned are irrelevant. . . . The test, in
    other words, involves no consideration of the actual mindset of the particular
    suspect subjected to police questioning.’’ (Citation omitted; internal quota-
    tion marks omitted.) J. D. B. v. North Carolina,           U.S.     ,

    Of course, when the police entered the apartment and confronted the
    defendant, they could not have told her that she necessarily would be free
    to leave upon completion of the search because, before conducting the
    search, the police did not know whether she ultimately would be arrested.
    They could have told the defendant, however, that, at that time, she was
    not under arrest and that she was being detained solely for the purpose of
    the safe and efficient execution of the search warrant.

    Another such seizure is the Terry stop. Terry v. Ohio,

    16
    Although this factor invariably has been treated as an important one
    for purposes of determining custody, many courts have concluded that,
    under the circumstances of the particular case, advising the suspect that
    he was not under arrest and was free to leave was insufficient to support
    a conclusion that he was not in custody for purposes of Miranda, even
    when the questioning was conducted in the suspect’s home. See, e.g., United
    States v. 
    Hashime, supra
    , 
    734 F.3d 284
    (‘‘[T]o the extent that law enforcement
    told [the defendant] that he did not have to answer questions and was
    free to leave, that by itself does not make the interrogation [noncustodial].
    Although a statement that the individual being interrogated is free to leave
    may be highly probative of whether, in the totality of the circumstances, a
    reasonable person would have reason to believe he was in custody, such a
    statement is not . . . sufficient in and of itself to show a lack of custody.’’
    [Internal quotation marks omitted.]); United States v. Cavazos, 
    668 F.3d 190
    , 195 (5th Cir. 2012) (‘‘The [g]overnment places significant emphasis on
    the fact that the agents informed [the defendant] that the interview was
    [noncustodial]. Such statements, while clearly relevant to a Miranda analy-
    sis, are not a talismanic factor. . . . [Rather] [t]hey must be analyzed for
    their effect on a reasonable person’s perception [at the time they are made],
    and weighed against opposing facts.’’ [Citations omitted; internal quotation
    marks omitted.]); United States v. 
    Craighead, supra
    , 
    539 F.3d 1088
    (‘‘The
    mere recitation of the statement that the suspect is free to leave or terminate
    the interview . . . does not render an interrogation [noncustodial] per se.
    We must consider the delivery of these statements in the context of the
    scene as a whole.’’ [Emphasis in original.]).
    17
    The state asserts that the defendant’s detention was akin to a Terry
    stop; Terry v. Ohio, 
    392 U.S. 1
    , 30, 
    88 S. Ct. 1868
    , 
    20 L. Ed. 2d 889
    (1968);
    which, as we previously noted; see footnote 11 of this opinion; has been
    deemed noncustodial for purposes of Miranda. Under the circumstances
    of the present case, we disagree with the state’s contention. Ordinarily, a
    Terry stop is made by one or perhaps two officers, frequently in public
    view. When an officer approaches and questions a suspect in accordance
    with Terry, most often, it will be apparent to the suspect that the officer’s
    inquiries are preliminary to more formal action, if any. Thus, although a
    Terry stop entails a curtailment of the suspect’s freedom of movement that
    is not slight or trivial, such a stop, like a traffic stop, has been characterized
    as ‘‘comparatively nonthreatening’’ and ‘‘noncoercive . . . .’’ Berkemer v.
    
    McCarty, supra
    , 
    468 U.S. 440
    . In marked contrast, the circumstances sur-
    rounding the search in the present case—including the fact that it was
    conducted out of public view by a large contingent of armed officers, none
    of whom informed the defendant of the duration of her detention—leads
    us to conclude that that search and Hicks’ questioning were conducted in
    a coercive and intimidating environment.

    The jury learned about the controlled purchases of heroin by the confi-
    dential informants because, at trial, the defense introduced the search war-
    rant affidavit into evidence. The informants did not testify at the suppression
    hearing or at trial.
    20
    The state introduced conflicting testimony about where the police dis-
    covered the buy money and the two cell phones. Neither testimonial inconsis-
    tency, however, bears on our determination of whether the improper
    admission of the defendant’s statements was harmful.
