    STATE OF CONNECTICUT v. DANTE
    ALEXANDER HUGHES
    (SC 20268)
    Robinson, C. J., and McDonald, D’Auria,
    Kahn, Ecker and Keller, Js.
    Syllabus
    Convicted of the crimes of manslaughter in the first degree with a firearm
    and criminal possession of a firearm in connection with the shooting
    death of the victim, the defendant appealed to this court, claiming that
    the state had failed to satisfy its burden of disproving his claim of self-
    defense beyond a reasonable doubt and that the trial court improperly
    had denied his motion for a new trial on the ground of juror misconduct.
    While the defendant and his girlfriend, K, were drinking and socializing
    at a bar, they began to argue, and K struck the defendant in the face
    with a beer bottle. K then left the bar with the keys to their vehicle,
    and the defendant followed her. At the request of a bartender, several
    patrons, including the victim, went outside to check on K. As K was
    seated in the driver’s seat of the couple’s vehicle, the defendant punched
    her in the face. The victim and another patron pulled the defendant
    away from K, and the defendant and the victim started to argue. Another
    patron intervened, and the situation appeared to have calmed down,
    but, moments later, the defendant shot the victim three times with a
    gun that he had removed from the vehicle and then fled the scene.
    Shortly thereafter, the defendant fled to Canada. At trial, the defendant
    asserted that he had acted in self-defense and offered his account of
    the events. He testified, inter alia, that, at the time of the shooting, he
    thought that the victim was reaching for a gun because the victim
    had threatened him and had reached into the waistband of his pants.
    Following his conviction, the defendant filed a motion for a new trial on
    the ground of juror misconduct after learning that, during deliberations,
    a juror, J, had consulted a dictionary for the definition of ‘‘manslaughter.’’
    Following a hearing, at which the jurors, including J, were individually
    questioned, the trial court, relying on the standard set forth in State v.
    Johnson (
    288 Conn. 236
    ), denied the defendant’s motion, concluding
    that no actual prejudice had resulted from J’s misconduct. Held:
    1. The state presented sufficient evidence to satisfy its burden of disproving
    the defendant’s claim of self-defense beyond a reasonable doubt, there
    having been ample evidence to support a finding that, at the time of
    the shooting, the defendant did not subjectively or reasonably believe
    that the victim was about to draw a gun and to use deadly physical
    force against him: the evidence provided a reasonable basis for the jury
    to find that the victim was not armed and never acted in a violent or
    menacing manner toward the defendant and that, from the victim’s
    perspective, the confrontation had deescalated and appeared to be
    resolved just before the shooting; moreover, the jury was free to discredit
    the defendant’s version of events and to credit the testimony of the other
    witness and reasonably could have rejected the defendant’s dubious
    explanation that he had retrieved his loaded gun, moments before shoot-
    ing the victim, to safeguard it rather than to use it to shoot the victim;
    furthermore, the jury could have given weight to the fact that, prior to
    the defendant’s interview with the police, he never claimed to have
    acted in self-defense and the fact that, when he finally did so, he gave
    inconsistent accounts, and there was significant consciousness of guilt
    evidence from which the jury was free to infer that the defendant knew
    that his conduct was wrongful.
    2. This court concluded that the presumption of prejudice articulated in
    Remmer v. United States (
    347 U.S. 227
    ) applies when a defendant demon-
    strates that a juror consulted a dictionary definition of a material term
    that substantively differed from the legal definition of that term provided
    by the trial court, thereby shifting the burden to the state to prove that
    the exposure to the definition was harmless beyond a reasonable doubt;
    in the present case, the defendant established his entitlement to the
    presumption of prejudice, as the dictionary definition that the juror
    consulted was of an essential legal term and it differed materially from
    the trial court’s definition of the elements of manslaughter.
    3. The trial court properly denied the defendant’s motion for a new trial,
    that court having correctly concluded that the juror misconduct caused
    no actual prejudice to the defendant, and, accordingly, the state’s burden
    of proving that the misconduct was harmless necessarily was met: this
    court was not persuaded by the defendant’s contention that the trial
    court applied an incorrect legal standard simply because it framed its
    inquiry into the juror misconduct in terms of the misconduct’s effect
    on the jurors’ impartiality, as it was apparent that that court ascribed
    the proper, broader meaning to the term impartiality and that it used
    the term to encompass the critical questions relevant to a proper inquiry
    into the matter; moreover, the record clearly established that there was
    no reasonable possibility that any member of the jury relied on the
    dictionary definition to the defendant’s detriment in reaching the verdict,
    as the trial court credited J’s testimony that he had relied on only
    the court’s instruction defining manslaughter and that the dictionary
    definition of manslaughter did not influence his decision in the case,
    and the other jurors credibly testified that their impartiality remained
    unaffected by any potential exposure to the extrinsic dictionary defini-
    tion, which dispelled any concern about their ability to be fair and
    impartial; furthermore, the trial court’s conclusion was bolstered by the
    fact that the misconduct occurred before the court specifically directed
    the jury not to consult the dictionary and to rely exclusively on the
    elements noted in the court’s instruction on the crime of manslaughter,
    and it was reasonable to presume that the jurors followed the court’s
    instructions.

    Procedural History
    Substitute informations charging the defendant with
    the crimes of murder and criminal possession of a fire-
    arm, brought to the Superior Court in the judicial dis-
    trict of New London, where the murder charge was
    tried to the jury before Jongbloed, J.; verdict of guilty
    of the lesser included offense of manslaughter in the
    first degree with a firearm; thereafter, the charge of
    criminal possession of a firearm was tried to the court,
    Jongbloed, J.; finding of guilty; judgment of guilty in
    accordance with the jury’s verdict and the court’s find-
    ing; subsequently, the court denied the defendant’s
    motion for a new trial, and the defendant appealed this
    court. Affirmed.

    Opinion
    KELLER, J. Following a jury trial, the defendant,
    Dante Alexander Hughes, was convicted of manslaugh-
    ter in the first degree with a firearm in violation of
    General Statutes § 53a-55a, after the jury found him not
    guilty of murder but rejected his claim of self-defense.
    In a subsequent trial to the court, the defendant was
    found guilty of criminal possession of a firearm in viola-
    tion of General Statutes § 53a-217 in connection with
    the same incident. On appeal,1 the defendant claims
    that the evidence presented at trial was insufficient
    to disprove, beyond a reasonable doubt, any of the
    elements of self-defense because the state failed to pres-
    ent affirmative evidence that discredited the defen-
    dant’s testimonial account of the incident. The defen-
    dant also claims that the trial court improperly denied
    his motion for a new trial on the ground of juror miscon-
    duct, specifically, a juror’s consultation of a dictionary
    definition of ‘‘manslaughter,’’ because the court applied
    an incorrect legal standard and misallocated the burden
    of proof. We affirm the judgment of conviction.
    The record reveals the following facts, which the jury
    reasonably could have found, and procedural history.2
    In the early morning hours of December 11, 2016, the
    defendant and his girlfriend, Latoya Knight, stopped for
    a drink at Ryan’s Pub, a neighborhood bar in Groton,
    after Knight picked the defendant up from work in the
    couple’s Nissan Armada. Knight was already intoxicated
    when the couple arrived at the pub. While the defendant
    and Knight were inside the pub, the defendant engaged
    in a friendly conversation with two other patrons, John
    Hoyt and then the victim, Joseph Gingerella.
    At some point, the defendant and Knight started
    arguing. Knight slapped a beer bottle out of the defen-
    dant’s hand, picked it up, and hit him in the face with
    it. She then demanded the keys to the Armada and
    stormed outside through the pub’s side door with the
    keys in hand. When the defendant went to follow her,
    the pub’s bartender, Rachel Smith, tried to stop him
    because she could see that he was angry and told him
    not to hurt Knight. The defendant pushed Smith away
    and continued to follow Knight. Smith then asked
    Andrew Flynn, another patron, Hoyt, and the victim to
    check on Knight.
    When the defendant reached the Armada, Knight was
    sitting in the driver’s seat. The defendant opened the
    door and punched Knight multiple times in the face,
    causing her nose to bleed. Hoyt and the victim then
    approached the Armada, positioned themselves on
    either side of the defendant, and attempted to stop the
    assault. Hoyt put his hands underneath the defendant’s
    arms and tried to pull him away. The victim also tried
    to pull the defendant away from Knight and yelled,
    ‘‘[y]ou’re not gonna hit her like that! . . . [Y]ou’re not
    gonna put your hand[s] on her!’’ The defendant and
    the victim continued arguing, and Flynn intervened by
    extending his arms between the two of them and telling
    them to ‘‘chill.’’
    Another pub patron observing the incident, Elvira
    Gonzalez, saw both Flynn and the victim gesture with
    their hands for the defendant to calm down. Smith, who
    had gone outside to tell everyone to calm down, saw
    Flynn gesture to her that everything was okay. Seconds
    later, several witnesses present at the scene heard mul-
    tiple gunshots fired, but no one saw the defendant pull
    the trigger or observed the victim immediately before
    he was fatally shot.3 After Hoyt heard the shots, he
    turned around to see what had happened and saw the
    defendant holding a gun and the victim lying on the
    ground, shielding himself with his hand up. The defen-
    dant then fled the scene.
    The defendant went to his home, changed his clothes,
    and made phone calls to his two brothers, his sister, and
    his mother. Thereafter, one of the defendant’s brothers
    picked him up and drove him to the Norwich home of
    their uncle, Shelton Rawls. The defendant told Rawls
    that he had shot someone after telling that person to
    mind his own business and to leave him and Knight
    alone, and that he thought he had killed this person.
    He asked Rawls to cut his hair, and Rawls then cut
    off the defendant’s green dreadlocks. The defendant’s
    other brother met the defendant at Rawls’ house later
    that morning to give the defendant a new prepaid cell
    phone. Before turning off the subscriber phone that he
    had been using, the defendant sent a text message to
    his work supervisor that stated, ‘‘[n]ot coming in for a
    long time . . . .’’
    The defendant made arrangements to be driven to
    Boston, Massachusetts, by one of his brother’s friends
    and decided to make his way across the Canadian bor-
    der from there. While heading to Canada, the defendant
    called several family members using the prepaid phone
    but used a function on the phone that prevents the
    person receiving the call from seeing the phone number
    of the person who is calling. The defendant made a
    stop at Niagara Falls, New York, and threw the gun that
    he had used to shoot the victim into the Niagara River.
    Afterward, he walked across a bridge into Canada,
    where he was detained by Canadian border agents.
    Nine days after the shooting, Groton police detectives
    drove to Canada, took custody of the defendant, and
    brought him back to Connecticut, where he was placed
    under arrest. Groton detectives subsequently interro-
    gated the defendant. For most of the approximately
    two hour interrogation, the defendant denied any
    involvement in the shooting. He falsely claimed that he
    had left the area before the shooting occurred and had
    no idea how it happened. He also falsely claimed that
    he did not own a gun, had fought with Knight outside
    the pub but no one intervened, had left the pub after
    calling a cab to take him to the bus station, had cut his
    hair in Buffalo, New York, because he had an upcoming
    job interview, and had traveled to Canada for enjoy-
    ment. At one point, when the interrogating officers
    urged the defendant to tell them the real story because
    they already knew that he had shot the victim, he
    responded, ‘‘[y]ou got no cameras.’’ Approximately one
    hour and forty minutes into the interrogation, the defen-
    dant admitted that he had shot the victim but claimed
    to have done so in self-defense. He claimed that the
    victim had started to pull up his shirt, and the defendant
    ‘‘thought [that the victim] was reaching for something
    . . . that he was going for a gun.’’ He stated that he
    was trying to protect himself and was ‘‘not trying to
    kill [the victim].’’ He also indicated that he ‘‘didn’t know
    [that the victim] didn’t have nothin’.’’
    In two substitute informations, the defendant was
    charged with murder in violation of General Statutes
    § 53a-54a (a) and criminal possession of a firearm. At
    trial, the defendant asserted a defense of self-defense.
    The state disputed that the defendant had acted in self-
    defense but also argued that he was not entitled to the
    defense because he had a duty to retreat.4 At the close
    of evidence, pursuant to the state’s request, the trial
    court instructed the jury on both murder and the lesser
    included offense of manslaughter in the first degree
    with a firearm. The court also instructed the jury on
    its obligation to consider whether the defendant acted
    in self-defense, if it found the defendant guilty of
    either crime.
    The jury found the defendant guilty of manslaughter
    in the first degree with a firearm, and the court there-
    after found the defendant guilty of criminal possession
    of a firearm. The court rendered judgment in accor-
    dance with the verdict and its finding, and imposed a
    total effective sentence of fifty years of imprisonment,
    execution suspended after forty-five years, followed by
    five years of probation.
    Following his conviction, the defendant filed a
    motion for a new trial on the ground of juror miscon-
    duct, after learning that, during deliberations, a juror
    had consulted a dictionary for the definition of ‘‘man-
    slaughter.’’ The trial court recognized that misconduct
    had occurred but, following a hearing, denied the
    motion, concluding that no actual prejudice resulted
    from the misconduct. This appeal followed. Additional
    facts and procedural history will be set forth as neces-
    sary.
    I
    The defendant’s first claim is that he is entitled to
    an acquittal on the charge of manslaughter in the first
    degree with a firearm because the state failed to meet
    its burden, pursuant to General Statutes § 53a-12 (a),
    of disproving, beyond a reasonable doubt, any of the
    elements of his self-defense claim. He contends that
    the state was obligated to present affirmative evidence
    to discredit his testimonial account of what occurred
    at the precise moment of the shooting. Specifically, he
    claims that the state failed (1) to present affirmative
    evidence that the victim did not make a gesture that
    the defendant could reasonably have believed was as
    an attempt to reach for a deadly weapon, or (2) to
    establish the statutory disqualification for self-defense
    of failure to retreat. The state asserts that it can, and
    did, satisfy its burden of persuasion through direct and
    circumstantial evidence proving that the defendant did
    not reasonably believe that the victim was about to use
    deadly physical force against him. We agree with the
    state. Therefore, we need not consider the state’s alter-
    native claim that, even if the defendant had held such
    a belief, the jury reasonably could have concluded that
    he had a duty to retreat.
    The defendant did not raise this insufficiency claim in
    the trial court, but his unpreserved claim is nonetheless
    reviewable under State v. Golding, 
    213 Conn. 233
    , 239–
    40, 
    567 A.2d 823
     (1989), as modified by In re Yasiel R.,
    
    317 Conn. 773
    , 781, 
    120 A.3d 1188
     (2015). We have
    previously recognized that ‘‘any defendant found guilty
    on the basis of insufficient evidence has been deprived
    of a constitutional right, and would therefore necessar-
    ily meet the four prongs of Golding.’’5 (Internal quota-
    tion marks omitted.) State v. Revels, 
    313 Conn. 762
    , 777,
    
    99 A.3d 1130
     (2014), cert. denied, 
    574 U.S. 1177
    , 
    135 S. Ct. 1451
    , 
    191 L. Ed. 2d 404
     (2015). Because there is no
    independent significance of a Golding analysis in this
    context, we review an unpreserved sufficiency of the
    evidence claim as though it had been preserved. See
    State v. Adams, 
    225 Conn. 270
    , 276 n.3, 
    623 A.2d 42
    (1993).
    We begin with the theory of self-defense advanced
    by the defendant and then turn to the relevant legal
    principles. The defendant offered the following account
    in his testimony. The defendant was assaulting Knight
    inside the Armada while Hoyt and the victim were trying
    to pull him off of her. During the struggle between the
    defendant and the victim, the victim called him a ‘‘bitch
    ass’’ and an offensive racial epithet, and also stated that
    he would ‘‘F [him] up . . . .’’ The defendant did not
    have a gun on him at that time but retrieved his Glock
    nine millimeter pistol from the overhead console of the
    Armada and placed it in his pocket when he saw that
    Knight was starting the Armada in an attempt to leave.
    He did so because he was concerned that, given Knight’s
    intoxicated state, the police might stop the Armada and,
    in turn, discover the gun. The gun was already loaded
    and cocked when the defendant removed it from the
    Armada. The defendant then started to walk away from
    the Armada, while Hoyt and the victim remained with
    Knight. When he got one or two parking spaces past
    the Armada, where it was kind of dark, he had an ‘‘urge’’
    to turn around and, upon doing so, saw the victim
    approximately fifteen feet away. The victim said noth-
    ing, but he reached into his waistband. The defendant
    thought that the victim was going to shoot him, so the
    defendant ‘‘came up and just shot.’’ The defendant was
    unsure whether any bullets actually struck the victim.
    On cross-examination, the defendant admitted that,
    after the shooting, he had contacted relatives, changed
    his appearance (clothes and hair), switched cell phones,
    tried to conceal the source of his outgoing calls, and
    gone to Canada. He also admitted that he gets ‘‘fired
    up’’ when people lay hands on him. In explaining why
    Knight deserved the beating that he had inflicted on
    her, he stated, ‘‘you know, you just take nothing from
    nobody. Once somebody puts their hands on you, you
    know, you have [a] right to defend yourself.’’
    We assess this evidence, as well as the other evidence
    adduced by the state, pursuant to the following princi-
    ples. ‘‘Under our Penal Code, self-defense, as defined
    in [General Statutes] § 53a-19 (a) . . . is a defense,
    rather than an affirmative defense. See General Statutes
    § 53a-16.’’ (Citation omitted.) State v. Clark, 
    264 Conn. 723
    , 730, 
    826 A.2d 128
     (2003). Whereas an affirmative
    defense requires the defendant to establish his claim by
    a preponderance of the evidence; see General Statutes
    § 53a-12 (b); a properly raised defense places the burden
    on the state to disprove the defendant’s claim beyond
    a reasonable doubt. See General Statutes § 53a-12 (a).
    ‘‘Consequently, a defendant has no burden of persua-
    sion for a claim of self-defense; he has only a burden
    of production. That is, he merely is required to introduce
    sufficient evidence to warrant presenting his claim of
    self-defense to the jury. . . . Once the defendant has
    done so, it becomes the state’s burden to disprove the
    defense beyond a reasonable doubt.’’ (Citation omitted;
    internal quotation marks omitted.) State v. Clark, supra,
    730–31. ‘‘As these principles indicate, therefore, only
    the state has a burden of persuasion regarding a self-
    defense claim . . . .’’ (Internal quotation marks omit-
    ted.) State v. O’Bryan, 
    318 Conn. 621
    , 631, 
    123 A.3d 398
     (2015).
    Because the state bears the burden of disproving self-
    defense, the standard for reviewing claims of insuffi-
    cient evidence in conjunction with a defense of justifica-
    tion such as self-defense is essentially the same standard
    used when examining claims relating to insufficient proof
    of the elements of a charged offense. See State v. Revels,
    supra, 
    313 Conn. 778
    . ‘‘A party challenging the validity of
    the jury’s verdict on grounds that there was insufficient
    evidence to support such a result carries a difficult
    burden.’’ (Internal quotation marks omitted.) State v.
    Rhodes, 
    335 Conn. 226
    , 233, 
    249 A.3d 683
     (2020). In
    reviewing the sufficiency of evidence, we apply a two
    part test. ‘‘First, we construe the evidence in the light
    most favorable to sustaining the verdict. Second, we
    determine whether upon the facts so construed and
    the inferences reasonably drawn therefrom the [jury]
    reasonably could have concluded that the cumulative
    force of the evidence established guilt beyond a reason-
    able doubt . . . .’’ (Internal quotation marks omitted.)
    State v. Allan, 
    311 Conn. 1
    , 25, 
    83 A.3d 326
     (2014). In
    doing so, we are mindful that ‘‘the trier of fact is not
    required to accept as dispositive those inferences that
    are consistent with the defendant’s innocence. . . .
    The trier [of fact] may draw whatever inferences from
    the evidence or facts established by the evidence it
    deems to be reasonable and logical.’’ (Internal quotation
    marks omitted.) State v. Drupals, 
    306 Conn. 149
    , 158,
    
    49 A.3d 962
     (2012). ‘‘[W]e do not ask whether there is
    a reasonable view of the evidence that would support
    a reasonable hypothesis of innocence. We ask, instead,
    whether there is a reasonable view of the evidence
    that supports the [jury’s] verdict of guilty.’’ (Internal
    quotation marks omitted.) State v. Rhodes, supra, 229.
    ‘‘[I]t does not diminish the probative force of the evi-
    dence that it consists, in whole or in part, of evidence
    that is circumstantial rather than direct.’’ (Internal quo-
    tation marks omitted.) State v. Niemeyer, 
    258 Conn. 510
    , 517, 
    782 A.2d 658
     (2001). Thus, in the present case,
    we construe the evidence and all the reasonable infer-
    ences drawn therefrom in the light most favorable to
    supporting the jury’s rejection of the defendant’s defense.
    Section 53a-19 sets forth the narrow circumstances
    in which a person is justified in using deadly physical
    force on another person in self-defense. Under § 53a-
    19 (a), ‘‘a person may justifiably use deadly physical
    force in self-defense only if he reasonably believes both
    that (1) his attacker is using or about to use deadly
    physical force against him, or is inflicting or about to
    inflict great bodily harm, and (2) that deadly physical
    force is necessary to repel such attack. . . . [T]he test
    a jury must apply . . . is a subjective-objective one.
    The jury must view the situation from the perspective
    of the defendant . . . [but] . . . the defendant’s belief
    ultimately must be found to be reasonable.’’6 (Internal
    quotation marks omitted.) State v. Reddick, 
    174 Conn. App. 536
    , 552, 
    166 A.3d 754

    Thus, with regard to the first requirement of self-
    defense, the jury must make two separate affirmative
    determinations for the defendant’s claim of self-defense
    to succeed. The jury must determine whether, on the
    basis of all of the evidence presented, the defendant in
    fact believed that the victim was about to use deadly
    physical force.7 See, e.g., State v. Prioleau, 
    235 Conn. 274
    , 286, 
    664 A.2d 743
     (1995). This initial determination
    typically requires the jury to assess the veracity of wit-
    nesses, often including the defendant, and to determine
    whether the defendant’s account of his belief is in fact
    credible. 
    Id.
     If the jury determines that the defendant
    did not believe that the victim was about to use deadly
    physical force when the defendant employed deadly
    force, the defendant’s self-defense claim must fail. 
    Id., 287
    . Even if the jury finds that the defendant may have
    held such a belief, if that belief was not objectively
    reasonably, the self-defense claim must fail. See 
    id.
    It bears emphasizing that, in making these determina-
    tions, the trier of fact is entitled to believe or disbelieve
    all, part, or none of any witness’ testimony, and the fact
    that certain evidence is not controverted does not mean
    that it must be credited. See State v. DeMarco, 
    311 Conn. 510
    , 520 n.4, 
    88 A.3d 491
     (2014); State v. Brown,
    
    299 Conn. 640
    , 648, 
    11 A.3d 663
     (2011); E. Prescott,
    Tait’s Handbook of Connecticut Evidence (6th Ed.
    2019) § 6.23.8, p. 378. The credibility of a witness may
    be impeached by showing, inter alia, that the witness
    is biased due to having an interest in the matter; see
    Conn. Code Evid. § 6-5; or that the witness made a prior
    inconsistent statement. See Conn. Code Evid. § 6-10.
    These well established principles disprove the defen-
    dant’s contention that, in the absence of affirmative
    evidence from at least one other witness of what hap-
    pened between the defendant and the victim in the
    moments immediately before the defendant fired his
    gun, the jury must accept the defendant’s testimony in
    determining whether he reasonably believed that the
    victim was reaching for a gun, thereby justifying his use
    of deadly physical force on the victim. This argument
    ignores the fact that the jury was free to reject the
    defendant’s testimony as to his belief after considering
    any other evidence, including other portions of the
    defendant’s testimony and his prior statements, that
    was inconsistent with his self-defense claim. The jury
    similarly was free to discredit the defendant’s version
    of the events immediately preceding and following the
    shooting and, instead, could have credited the testi-
    mony of the other witnesses. When presented with con-
    flicting accounts, the jury is not required to accept the
    testimony and inferences offered on behalf of the defen-
    dant. See, e.g., State v. James E., 
    154 Conn. App. 795
    ,
    815, 
    112 A.3d 791
     (2015) (evidence was sufficient to
    disprove self-defense beyond reasonable doubt), aff’d,
    
    327 Conn. 212
    , 
    173 A.3d 380
     (2017).
    The defendant’s argument mistakenly assumes that
    his testimony was the only evidence presented to the
    jury that was relevant to his claim of self-defense. As
    we explain more fully hereinafter, it was not. Although
    the jury is not free to merely disbelieve the defendant
    and to conclude that the opposite of what he said was
    true; see Ventura v. East Haven, 
    330 Conn. 613
    , 641–42,
    
    199 A.3d 1
     (2019); State v. Alfonso, 
    195 Conn. 624
    , 634,
    
    490 A.2d 75
     (1985); the jury may reject his self-defense
    claim if other evidence and reasonable inferences
    drawn therefrom undermine the credibility of his
    account. See State v. Grasso, 
    189 Conn. App. 186
    , 212–
    13, 
    207 A.3d 33
    , cert. denied, 
    331 Conn. 928
    , 
    207 A.3d 519
     (2019) (evidence of blackmail by victim and its
    effect on defendant supports jury’s rejection of self-
    defense claim, even though only victim and defendant
    were present when shooting occurred); State v. Cruz,
    
    75 Conn. App. 500
    , 519, 
    816 A.2d 683
     (2003) (defendant’s
    argument, based mostly on his own testimony, that only
    reasonable conclusion jury could have reached was that
    he acted in self-defense ‘‘relates to witness credibility,
    not sufficiency of the evidence’’), aff’d, 
    269 Conn. 97
    ,
    
    848 A.2d 445
     (2004).
    Having reviewed the evidence in its entirety, and con-
    struing it in the light most favorable to sustaining the
    verdict, we conclude that there was a rational view of
    the evidence that proved beyond a reasonable doubt
    that, at the time of the shooting, the defendant did not
    reasonably believe that the victim was about to use
    deadly physical force against him.
    The evidence provided an ample basis for the jury
    to find that the victim was not in fact armed and never
    acted in a violent or menacing manner toward the defen-
    dant. No weapon was found on or near the victim after
    the shooting.8 The defendant did not claim that the
    victim ever mentioned having a gun or any other
    weapon. None of the witnesses to the events occurring
    outside the pub, including the victim’s nearby compan-
    ions, heard the victim threaten the defendant or use
    the language the defendant described.9 The victim
    attempted to pull the defendant away from Knight but
    never attempted to inflict any physical injury on the
    defendant. Flynn testified that the argument between
    the defendant and the victim ‘‘didn’t seem too serious.’’
    The evidence also provided a reasonable basis for
    the jury to find that, from the victim’s perspective, the
    confrontation had deescalated and then appeared to
    have been resolved just before the shooting. Gonzalez
    saw both Flynn and the victim gesture with their hands
    for the defendant to calm down and observed what she
    characterized as a peaceful conversation. After Smith
    went outside to tell everyone to calm down so that she
    would not have to call the police, Flynn gestured to
    her that everything was okay, and she returned inside.
    Flynn, Smith, and Gonzalez turned away from observing
    the defendant and the victim, and headed back toward
    the pub because they believed that the situation had
    been amicably resolved. According to the testimony of
    Knight, Hoyt, Smith, and Gonzalez, there was no cause
    for the victim to become further agitated. Knight was
    safe, and the effort undertaken by the victim and his
    friends to defend her had concluded. The defendant
    had begun to walk away. The collective force of this
    evidence provided a persuasive basis for the jury to
    conclude that, even if it were to accept the defendant’s
    assertion that the victim moved his hand in the vicinity
    of the waistband of his pants, there was no reasonable
    basis for the defendant to believe that the victim was
    about to draw a gun.
    The jury also reasonably could have rejected the dubi-
    ous explanation that the defendant gave for retrieving
    his loaded gun, moments before firing three shots at
    the victim. If the defendant actually had been concerned
    about the consequences of Knight’s driving while intoxi-
    cated and being found in possession of an illegal fire-
    arm, the most effective course of action would have
    been to withhold the keys to the Armada in the first
    place or to take them back from her, not to retrieve
    the gun from the console. His choice of action and its
    timing left the jury free to infer that the defendant had
    retrieved the gun not to safeguard it but to use it.
    The jury also could have given weight to the fact that,
    prior to his video-recorded interview with the police
    approximately nine days after the shooting, the defen-
    dant never claimed to have acted in self-defense. He
    admitted that he had never suggested it to the relatives
    and friends with whom he spoke after the shooting.
    Instead, he told Rawls, hours after the shooting, that
    he had shot and possibly killed someone after that per-
    son had interceded in an argument between the defen-
    dant and Knight and the defendant told him to mind
    his own business. Rawls inferred from what he had
    been told that the victim must not have heeded the
    defendant’s direction. When the defendant finally
    claimed to have acted in self-defense, he gave inconsis-
    tent accounts, in his police interview and at trial, of the
    particulars.
    Finally, the jury’s verdict was supported by signifi-
    cant consciousness of guilt evidence. In the self-defense
    context, such evidence ‘‘tend[s] to show that the defen-
    dant believed that what he had done was not merely
    an act of self-defense, but [was] something that was
    considered wrong in the eyes of the law.’’ State v.
    Thomas, 
    50 Conn. App. 369
    , 384, 
    717 A.2d 828
     (1998),
    appeal dismissed, 
    253 Conn. 541
    , 
    755 A.2d 179
     (2000).
    After shooting the victim, the defendant attempted to
    disguise himself by changing his appearance, fled the
    state, and then attempted to flee the country. He also
    attempted to conceal his whereabouts and to destroy
    evidence. The jury was free to reject his explanations
    for these actions and to infer that he was deliberately
    eluding the police to avoid prosecution for conduct he
    knew was wrongful. See State v. Ferrara, 
    176 Conn. 508
    , 516–18, 
    408 A.2d 265
     (1979).
    In its totality, the evidence provides ample support
    for the jury to conclude that the defendant did not
    believe, subjectively or reasonably, that the victim was
    about to draw a gun on him. Rather, the evidence sup-
    ports the jury’s reasonable conclusion that, when the
    defendant fired his gun at the victim, he was still pro-
    pelled by the rage he had just unleashed on Knight and
    angry about the victim’s interference in his business. We
    therefore conclude that there was sufficient evidence
    to disprove the defendant’s claim of self-defense beyond
    a reasonable doubt.
    II
    The defendant also claims that the trial court improp-
    erly denied his motion for a new trial on the ground of
    juror misconduct. He contends that the court’s conclu-
    sion that he suffered no actual prejudice from a juror’s
    consultation of a dictionary definition of ‘‘manslaugh-
    ter’’ rested on an incorrect legal standard and a misallo-
    cation of the burden of proof. We conclude that the
    trial court properly denied the defendant’s motion for
    a new trial.
    The record reveals the following additional relevant
    facts. In its final instructions to the jury, the trial court
    set forth the elements that the state was required to
    prove to establish murder or, alternatively, manslaugh-
    ter in the first degree with a firearm if it found the
    defendant not guilty of murder, as well as the elements
    of self-defense to consider should it find the defendant
    guilty of either offense. With respect to manslaughter,
    the court provided the statutory elements—that the
    defendant must have (1) engaged in conduct that cre-
    ated a grave risk of death, (2) acted recklessly, (3) acted
    under circumstances evincing an extreme indifference
    to human life, and (4) caused the death of the victim.10
    See General Statutes § 53a-55 (a) (3). The court also
    instructed the jury not to ‘‘look up anything on the
    Internet or make any private investigations of any kind,’’
    an instruction it had given numerous times during trial.
    It did not, however, reiterate an instruction given at the
    commencement of jury selection, almost one month
    earlier, that the jury should not look up any terms in
    a dictionary.11
    On the second day of deliberations, the jury sent a
    note asking the court to clarify certain aspects of the
    murder instruction and ‘‘whether it is permissible to
    look up the word manslaughter in the dictionary.’’ The
    court consulted with counsel and, with their agreement,
    instructed the jury that it ‘‘should use the definition of
    the specific charge of manslaughter as explained by its
    elements in [the court’s] instructions and not look up
    anything in any outside sources, including the diction-
    ary.’’12
    The following day, on July 26, 2018, the jury of twelve
    unanimously found the defendant guilty of manslaugh-
    ter in the first degree with a firearm. The jurors were
    individually polled, and each juror unequivocally
    affirmed his or her agreement with the verdict.
    On July 31, 2018, one of the jurors, D.M.,13 engaged
    in a postverdict conversation with courthouse staff. In
    that conversation, D.M. mentioned that one of the other
    jurors had looked up the definition of manslaughter in
    a dictionary. This information was reported to the trial
    court, which then scheduled a hearing to determine
    whether the jury, or any member thereof, had in fact
    looked up the definition of manslaughter in a dictionary,
    and what impact, if any, that action may have had on
    the jury’s deliberations.14
    Prior to the hearing, counsel agreed to the questions
    that would be posed by the court to each juror. In
    accordance with that agreement, each juror was ques-
    tioned as to whether the dictionary definition of man-
    slaughter had been raised during deliberations, and, if
    so, when this occurred; whether any outside informa-
    tion had affected the juror’s ability to sit fairly and
    impartially; whether any outside information had affected
    the juror’s ability to follow the court’s instructions; and
    whether the juror had considered only the evidence
    presented in the courtroom and only the court’s instruc-
    tions. After each juror was questioned, counsel was
    given the opportunity to propose follow-up questions.
    Although a few jurors recalled hearing a discussion
    about such a definition, they indicated that the discus-
    sion had been promptly shut down and that this incident
    had prompted the jury’s note to the court. Those jurors
    also testified that no dictionary had been brought into
    the jury room and that either no definition had been read
    aloud or they could not recall any dictionary definition.
    Each of the twelve jurors affirmed that no outside infor-
    mation had affected the juror’s ability to sit fairly and
    impartially, that no outside information had affected
    the juror’s ability to follow the court’s instructions, and
    that the juror had considered only the evidence pre-
    sented in the courtroom and only the court’s instruc-
    tions.
    One juror, J.B., admitted in the following exchange,
    however, that he had consulted a dictionary to obtain
    a definition of manslaughter:
    ‘‘The Court: . . . [I]t has come to the court’s atten-
    tion that there may have been a reference to or a discus-
    sion regarding a dictionary definition of manslaughter.
    . . . [W]hat can you tell us about that in terms of your
    knowledge of that?
    ‘‘[J.B.]: My knowledge of it, I had a general idea what
    manslaughter was, and I looked it up in the dictionary
    and [came] up with a definition.
    ‘‘The Court: All right. And then was that something
    you mentioned?
    ‘‘[J.B.]: Absolutely.
    ‘‘The Court: Yes. All right. . . . [D]o you recall
    whether that was before in time or after the note
    came out?
    ‘‘[J.B.]: That was before.
    ‘‘The Court: All right. So . . . after the note came
    out and the answer was received to the note that you
    were to consider the definition that the court provided
    . . . without going into any of the specific mental pro-
    cesses of the jury’s deliberation . . . did that outside
    information or any outside information affect your abil-
    ity to sit fairly and impartially as a juror in this case?
    ‘‘[J.B.]: Yeah, it did. I mean, the—it wasn’t the out-
    come I wanted, I could tell you that, but I mean, it is
    what it is, I think.
    ‘‘The Court: I guess my question is, you’ve indicated
    that you looked up the definition.
    ‘‘[J.B.]: Yep.
    ‘‘The Court: And you mentioned it. Then the jury sent
    out the note.
    ‘‘[J.B.]: Yep.
    ‘‘The Court: And the jury was given instructions from
    the court at that time. And those instructions were to
    consider only the definition that the court provided.
    ‘‘[J.B.]: Correct.
    ‘‘The Court: And my question is, did you follow the
    court’s instructions?
    ‘‘[J.B.]: I did.’’
    In response to the court’s next questions—whether
    that outside information, the dictionary definition,
    affected J.B.’s ability to sit fairly and impartially as a
    juror in the case and whether he considered information
    outside of the evidence in the courtroom and the court’s
    instructions in this case—J.B. started to address his
    own thought process and the vote count on the charges
    at a certain point in the deliberations. The trial court
    interrupted J.B. and emphasized that he should not
    reveal anything about any juror’s mental process in
    reaching a verdict.15 The inquiry then continued:
    ‘‘The Court: . . . [S]o, without going into that, my
    question is really whether any outside information, and
    you’ve indicated that you did have some outside infor-
    mation, and then you were told to . . . consider only
    the definition that the court provided, so my question
    is, did you in fact—did any outside information affect
    your ability to fairly and impartially decide this case?
    ‘‘[J.B.]: No.
    ‘‘The Court: And then, did you in fact consider—or
    did any outside information affect your ability to follow
    the court’s instructions in this case?
    ‘‘[J.B.]: No. I mean, I don’t know. I believe I settled.
    That’s what I believed. You know what I mean?
    ‘‘The Court: All right. I think I understand what
    you’re saying.
    ‘‘[J.B.]: Yes.
    ‘‘The Court: And, I guess lastly, were you able to
    consider and limit your consideration only to the evi-
    dence in the case, as well as the court’s instructions?
    ‘‘[J.B.]: Yes.’’
    After defense counsel requested follow-up questions
    to ascertain what J.B. had reviewed and why, the court
    elicited the following additional information. J.B. had
    looked up the definition of manslaughter in a Webster’s
    Dictionary, which he recalled defined the term as ‘‘tak-
    ing a man’s life without forethought or malice . . . .’’
    J.B. indicated that the ‘‘without forethought’’ aspect of
    the definition was important for the other jurors to
    know because it confirmed J.B.’s prior understanding
    of manslaughter to mean ‘‘an accidental thing.’’ This
    exchange then ensued:
    ‘‘The Court: All right. And are you telling us that
    the reason you looked it up was because it seemed
    inconsistent with what you had thought or—
    ‘‘[J.B.]: Sort of.
    ‘‘The Court: All right. I don’t want to put any words
    into your mouth.
    ‘‘[J.B.]: I mean, yeah. I mean, I just wanted to have
    an actual definition of what it was and—
    ‘‘The Court: All right. And then the court explained
    that you needed to use the definition that the court had
    provided.
    ‘‘[J.B.]: After that, I had done that, correct.
    ‘‘The Court: And that was afterward?
    ‘‘[J.B.]: Yes.
    ‘‘The Court: And did you follow the court’s instruc-
    tions?
    ‘‘[J.B.]: I mean, basically, I did.’’
    The defendant thereafter filed a motion for a new
    trial on the ground of prejudicial juror misconduct. The
    trial court denied the motion, concluding that ‘‘no actual
    prejudice resulted from the conduct’’ at issue. The court
    relied on the standard articulated in State v. Johnson,
    
    288 Conn. 236
    , 
    951 A.2d 1257
     (2008), in which this court
    emphasized the limitations on postverdict inquiry of
    jurors and then observed: ‘‘[O]nce a verdict has been
    reached, the proper inquiry does not involve a determi-
    nation of what conclusions the jurors actually drew
    but, rather, of whether the jurors were aware of or
    actually exposed to [extrinsic material], whether it
    affected their ability to be impartial and whether it was
    of such a nature that it probably rendered the juror[s]
    unfair or partial.’’ (Emphasis in original; internal quota-
    tion marks omitted.) 
    Id.,
     262–63.
    The trial court then applied these three inquiries to
    the present case. It first found that exposure to the
    dictionary definition was limited to one juror and that,
    with regard to the other jurors’ awareness, their
    responses credibly dispelled any concern that J.B.’s
    actions had tainted them. Second, the court found that
    the jurors’ credible assurances that their impartiality
    remained unaffected by any potential exposure to the
    extrinsic dictionary definition dispelled any concern
    about the jurors’ ability to be impartial. With respect
    to J.B. specifically, the court found that some of his
    answers were nonresponsive but interpreted those
    comments to simply reflect J.B.’s frustration that he
    had compromised to reach consensus with other jurors.
    The court found that J.B.’s subsequent answers dis-
    pelled any concerns of impartiality. Finally, the court
    found that the nature of the information was not of
    the sort to compel a finding of prejudice. The court
    concluded that our appellate case law did not deem
    reference to a dictionary inherently prejudicial. It also
    found no prejudice under the particular facts of this
    case because ‘‘utilization of [the] dictionary definition
    [of manslaughter] would be inconsistent with the actual
    verdict reached,’’ given the difference between that defi-
    nition and the statutory definition that the jury applied.16
    In considering the second and third Johnson inquiries,
    the court also relied on the black letter principle that,
    ‘‘[i]n the absence of a clear indication to the contrary,
    [the court] must presume that the jury followed [the
    court’s] instruction.’’ State v. Asherman, 
    193 Conn. 695
    ,
    737–38, 
    478 A.2d 227
     (1984), cert. denied, 
    470 U.S. 1050
    ,
    
    105 S. Ct. 1749
    , 
    84 L. Ed. 2d 814
     (1985). The trial court
    rejected the defendant’s reliance on case law from other
    jurisdictions, concluding that each case was factually
    distinguishable.
    In his appeal to this court, the defendant’s challenge
    to the legal standard applied by the trial court has sev-
    eral threads. We glean three distinct points. First, the
    defendant contends that the trial court incorrectly
    relied on the impartiality standard in State v. Johnson,
    
    supra,
     
    288 Conn. 262
    –63, because the misconduct in
    the present case is not of the type that raises concerns
    of juror partiality. He asserts that the trial court, instead,
    should have considered whether the extrinsic informa-
    tion interfered with J.B.’s ability to judge the case solely
    on the basis of the definition provided by the court,
    and whether the verdict was influenced by J.B.’s argu-
    ments in deliberations in reliance on the dictionary
    definition. Second, the defendant contends that the trial
    court improperly placed the burden on him to prove
    prejudice. Although there is a split of authority in other
    jurisdictions with respect to this issue, he contends
    that this court’s case law suggests that we follow the
    jurisdictions that would apply a presumption of preju-
    dice, which in turn would require the state to prove
    that there was no reasonable possibility that J.B.’s con-
    sultation of a dictionary influenced the verdict. Third,
    the defendant contends that the trial court improperly
    failed to determine that the state did not meet this
    burden. He asserts that this conclusion is compelled
    either by the testimony adduced at the hearing or under
    various objective tests applied by other jurisdictions to
    assess prejudice under such circumstances.17
    The state questions the defendant’s preservation of
    some of these issues but contends that, in any event,
    the trial court unambiguously allocated the burden of
    proof to the state, consistent with the state’s acknowl-
    edgment during the hearing on the motion for a new
    trial that a presumption of prejudice applied and that
    it had the burden to prove that there was no prejudice.
    The state further contends that it met this burden of
    proof no matter which test is applied.18
    Insofar as the defendant’s claims bear on the proper
    legal standard, they are subject to plenary review. See,
    e.g., Hartford v. CBV Parking Hartford, LLC, 
    330 Conn. 200

    (misallocation of burden of proof). Insofar, however,
    as they challenge the trial court’s assessment of the
    credibility of the jurors’ testimony at the hearing inquir-
    ing into the alleged misconduct, or the reasonableness
    of inferences drawn from such testimony, we review
    such assessments under the abuse of discretion stan-
    dard. See, e.g., State v. Dixon, 
    318 Conn. 495
    , 506–507,
    
    122 A.3d 542
     (2015); State v. Small, 
    242 Conn. 93
    , 113,
    
    700 A.2d 617
     (1997). See generally State v. Newsome,
    
    238 Conn. 588
    , 628, 
    682 A.2d 972
     (1996) (motion for
    new trial based on allegations of juror misconduct ‘‘is
    addressed to the sound discretion of the trial court and
    is not to be granted except on substantial grounds’’
    (internal quotation marks omitted)).
    We agree with the defendant, and the state’s conces-
    sion, that J.B.’s consultation of a dictionary definition
    of manslaughter was presumptively prejudicial under
    the circumstances in the present case and that the state
    bore the burden of proving that this juror misconduct
    was harmless. We do not share the state’s confidence
    that the trial court necessarily allocated the burden of
    proof to the state, as this matter was not expressly
    decided in the court’s decision on the defendant’s
    motion.19 Nonetheless, if the court correctly determined
    that the facts demonstrated that the defendant suffered
    no actual prejudice from the juror misconduct, the
    state’s burden of proof would be met.20 See State v.
    Berrios, 
    320 Conn. 265
    , 299, 
    129 A.3d 696
     (2016) (con-
    cluding that state overcame presumption of prejudice
    by proof that jurors’ impartiality was not affected by
    third-party contact); see also United States v. Olano,
    
    507 U.S. 725
    , 739, 
    113 S. Ct. 1770
    , 
    123 L. Ed. 2d 508
    (1993) (‘‘There may be cases [in which] an intrusion
    should be presumed prejudicial . . . but a presump-
    tion of prejudice as opposed to a specific analysis does
    not change the ultimate inquiry: Did the intrusion affect
    the jury’s deliberations and thereby its verdict?’’ (Cita-
    tions omitted.)). We conclude that the trial court’s deter-
    mination is supported by the law and the record in
    this case.
    A
    Our analysis is guided by the following principles.
    ‘‘Under the constitution of Connecticut, article first, § 8,
    and the sixth amendment to the United States constitu-
    tion, the right to a trial by jury guarantees to the crimi-
    nally accused a fair trial by a panel of impartial, indiffer-
    ent jurors.’’ (Internal quotation marks omitted.) State

    also Morgan v. Illinois,

    112 S. Ct. 2222
    , 
    119 L. Ed. 2d 492
     (1992). A necessary component
    of the right to an impartial jury is the right to have the
    jury decide the case ‘‘solely on the basis of the evidence
    and arguments given [it] in the adversary arena after
    proper instructions on the law by the court.’’ State v.
    Rodriguez, 
    210 Conn. 315

     (1989);
    see also Hughes v. Borg,

    , 700 (9th Cir.
    1990) (‘‘[s]tate defendants have a federal constitutional
    right to an impartial jury and jurors have a correlative
    duty to consider only the evidence that is presented in
    open court’’).
    ‘‘Consideration of extrinsic evidence is jury miscon-
    duct and has been found to be sufficient to violate the
    constitutional right to a trial by an impartial jury.’’ State
    v. McCall, 
    187 Conn. 73
    , 80, 
    444 A.2d 896
     (1982). Most
    courts treat a juror’s exposure to any extra-record infor-
    mation, whether relating to the facts or the law in the
    case, as a form of extrinsic evidence or influence. See,
    e.g., United States v. Pagán-Romero,

    tion obtained through juror consultation of a dictionary
    is generally considered to be extrinsic information and

    to assure a defendant a fair trial, not a perfect one.
    . . . [T]he constitution does not require a new trial
    every time a juror has been placed in a potentially
    compromising situation . . . [because] it is virtually
    impossible to shield jurors from every contact or influ-
    ence that might theoretically affect their vote.’’ (Internal
    quotation marks omitted.) State v. Tomasko,

     (1997); see also State v. Asherman,
    supra, 
    193 Conn. 736
     (‘‘Juror misconduct [that] results
    in substantial prejudice to the defendant is not to be
    tolerated. But not every irregularity in a juror’s conduct
    compels reversal. The dereliction must be such as to
    deprive the defendant of the continued, objective and
    disinterested judgment of the juror, thereby foreclosing
    the accused’s right to a fair trial.’’ (Internal quotation
    marks omitted.)). ‘‘The question is whether . . . the
    misconduct has prejudiced the defendant to the extent
    that he has not received a fair trial. . . . The defendant
    has been prejudiced if the misbehavior is such to make
    it probable that the juror’s mind was influenced by it
    so as to render him or her an unfair and prejudicial
    juror.’’ (Citation omitted; internal quotation marks omit-
    ted.) State v. Newsome, supra, 628.
    Although these principles are broadly accepted,
    courts are divided on whether exposure to certain
    extrinsic influences should be deemed presumptively
    prejudicial and, if so, whether such a presumption shifts
    the burden to the state to prove the harmlessness of
    the misconduct. See State v. Berrios, supra, 
    320 Conn. 284
    –92. This divide largely turns on whether the court
    has concluded that the presumption of prejudice articu-
    lated in Remmer v. United States, 
    347 U.S. 227
    , 229, 
    74 S. Ct. 450
    , 
    98 L. Ed. 654
     (1954) (Remmer presumption),
    a jury tampering case, retains its vitality or whether the
    court has interpreted subsequent United States
    Supreme Court case law to indicate that the due process
    holding in Remmer only entitles the defendant to a
    hearing, at which he bears the burden of proving actual
    prejudice. Although this court seemed to endorse the
    latter view in one case; see State v. Johnson, 
    supra,
     
    288 Conn. 254
    ; we expressly left this issue open in several
    other cases because the party claiming the presumption
    could not prevail, even if the burden of proof shifted
    to the state. See State v. Berrios, supra, 282–83 (noting
    that uncertainties resulting from post-Remmer cases
    created inconsistencies in our own case law and cit-
    ing cases).
    In State v. Berrios, supra, 
    320 Conn. 266
    –67, we finally
    weighed in on this issue. In that case, the defendant
    had moved for a mistrial after a juror reported that the
    defendant’s mother had made comments about the case
    to the juror during a trial recess. 
    Id., 269
    ; see footnote
    24 of this opinion. The trial court denied the defendant’s
    motion following a hearing at which the jurors were
    questioned about the contact and its effect. 
    Id.,
     269–73.
    We held that ‘‘the Remmer presumption is still good
    law with respect to external interference with the jury’s
    deliberative process via private communication, con-
    tact, or tampering with jurors that relates directly to
    the matter being tried.’’ (Footnote omitted.) 
    Id., 292
    .
    We explained that the defendant bears an initial burden
    of proving that the Remmer presumption applied,
    through proof that an extrajudicial contact or communi-
    cation occurred and that the contact or communication
    pertained to the matter before the jury. 
    Id.,
     293–94. We
    further explained that ‘‘the Remmer presumption is not
    conclusive. The burden rests heavily on the government
    to establish that the contact was harmless’’; (internal
    quotation marks omitted) 
    id., 294
    ; meaning that ‘‘there
    was no reasonable possibility that the tampering or
    misconduct affected the [jurors’] impartiality.’’ (Internal
    quotation marks omitted.) 
    Id.
    Although the holding in Berrios was limited to an
    extrinsic influence initiated by a third party, several
    factors indicate that the Remmer presumption also
    should apply in cases in which the extrinsic influence
    is brought to bear by a juror, at least in some such
    cases. We made a point in Berrios of favorably citing
    the position of the United States Court of Appeals for
    the Second Circuit that it is ‘‘well-settled that any extra-
    record information of which a juror becomes aware is
    presumed prejudicial’’; (internal quotation marks omit-
    ted) 
    id., 287
    ; as well as that of other jurisdictions that
    apply a presumption of prejudice to ‘‘serious, or not
    innocuous claims of external influence, such as jury
    tampering, bribery, or use of extra-record evidence.’’
    (Internal quotation marks omitted.) 
    Id.,
     288–89. One of
    the cases we favorably cited applied a presumption of
    prejudice to a juror’s use of a dictionary; see 
    id., 288
    ,
    citing United States v. Lawson, 
    677 F.3d 629
     (4th Cir.),
    cert. denied sub nom. Hutto v. United States, 
    568 U.S. 889
    , 
    133 S. Ct. 393
    , 
    184 L. Ed. 2d 162
     (2012); see also
    United States v. Lawson, 
    supra, 645
     (‘‘[the Remmer]
    presumption likewise is applicable when a juror uses
    a dictionary or similar resource to research the defini-
    tion of a material word or term at issue in a pending
    case’’). The court in Lawson observed that there is a
    split of authority as to whether a juror’s consultation
    of a dictionary is presumptively prejudicial that mirrors
    the jurisdiction’s view of the vitality of the Remmer
    presumption. United States v. Lawson, 
    supra, 645
    .
    We also observe that, even among those jurisdictions
    that do not view jurors’ consultation of a dictionary to
    be inherently prejudicial as a general matter, courts
    have recognized that an exception may exist when
    jurors are exposed to a dictionary definition of a mate-
    rial term that is manifestly inconsistent with the one
    provided by the court. See, e.g., United States v. Pagan-
    Romero, supra, 
    894 F.3d 447
    –48 (‘‘In general, the use
    of a dictionary will pose a qualitatively less serious risk
    of harm [than exposure to facts that could be used as
    evidence]. . . . Of course, exceptions to this general
    approach may arise, in cases where, for example, the
    dictionary definition was contrary to, or confusingly
    inconsistent with, the instructions, where the jurors
    confirmed that they had actually relied on the mis-
    leading definition, or where the court made an inade-
    quate effort to inquire into the impact of the taint.’’
    (Citation omitted.)). See generally Ryser v. State, supra,
    
    453 S.W.3d 42
     (discussing cases); annot., 
    35 A.L.R.4th 626
    , 631, 653, §§ 2[b] and 5[b] (1985) (same).
    Our lone ‘‘dictionary’’ case is not to the contrary. In
    State v. Asherman, supra, 
    193 Conn. 736
    , this court set
    forth the general proposition that ‘‘[c]onsideration of
    extrinsic evidence is presumptively prejudicial because
    it implicates the defendant’s constitutional right to a
    fair trial before an impartial jury. . . . But unless the
    nature of the misconduct on its face implicates his
    constitutional rights the burden is on the appellant to
    show that the error of the trial court is harmful.’’ (Cita-
    tions omitted.) We concluded in Asherman that the
    defendant was not prejudiced as a result of a juror’s
    consultation of a dictionary. Id., 737. In that case, nota-
    bly, the dictionary had been consulted for the meaning
    of a generic term, ‘‘inference,’’ which the trial court
    used but did not specifically define in its instructions,
    and the defendant’s concern that the jury could inter-
    pret one of the dictionary definitions to allow it to base
    inferences on speculation was alleviated by the trial
    court’s instructions regarding the use of inferences. Id.
    We adopted the logic that some other courts have fol-
    lowed; see footnote 21 of this opinion; under which
    definitions in a standard dictionary are assumed to be
    common knowledge and, thus, constitute knowledge
    that jurors are presumed to possess in the absence of
    an indication to the contrary. See State v. Asherman,
    supra, 737. See generally State v. Harris, 
    340 S.C. 59
    , 64,
    
    530 S.E.2d 626
     (2000) (‘‘[c]ourts have almost uniformly
    found no prejudice to the defendant when the dictionary
    definition did not vary from the ordinary meaning of
    the words or from the meaning contained in the trial
    court’s instructions’’). We had no occasion to consider
    whether a presumption of prejudice should apply when
    jurors consider a dictionary definition of a material
    term that directly conflicts with the legal definition
    provided by the trial court.
    We agree with those jurisdictions that have con-
    cluded that a presumption of prejudice applies if the
    defendant can demonstrate that a juror consulted a
    dictionary and was thereby exposed to a definition of
    a material term that substantively differed from the legal
    definition provided by the court, shifting the burden
    to the state to prove that this exposure was harmless
    beyond a reasonable doubt. See United States v. Law-
    son, supra, 
    677 F.3d 645
    –46 (holding that Remmer pre-
    sumption applies when juror uses dictionary to research
    definition of ‘‘a material word or term at issue in a
    pending case’’ and that it was of particular concern

    that addressed contested element of offense); United

    B
    Mindful of these principles, we turn to the particular
    claims raised by the defendant. We agree with the defen-
    dant that he established his entitlement to the presump-
    tion of prejudice. The dictionary definition that J.B.
    consulted was of an essential legal term, and it differed
    materially from the trial court’s definition of the ele-
    ments of manslaughter. The dictionary purportedly
    defined manslaughter as the taking of a life ‘‘without
    forethought or malice,’’ whereas the elements provided
    by the court required proof of recklessness and extreme
    indifference to human life. As we previously indicated,
    although we cannot say with certainty whether the trial
    court imposed the burden on the state to prove that
    consultation of the dictionary was harmless, the state’s
    burden necessarily would be met if the trial court cor-
    rectly determined that the evidence established that this
    conduct caused no actual prejudice to the defendant.
    To resolve this issue, we begin with the defendant’s
    contention that the trial court applied an incorrect legal
    standard. Specifically, he contends that the court’s
    application of the standard from State v. Johnson, 
    supra,
    288 Conn. 262
    –64, was incorrect because jurors’ consul-
    tation of a dictionary does not implicate concerns about
    the jurors’ impartiality but, rather, the possible misuse
    of the definition in reaching a verdict. We are not per-
    suaded that the trial court applied an incorrect legal
    standard simply because it framed its inquiry in terms
    of the misconduct’s effect on the jurors’ impartiality.
    As we previously indicated, the right to have a jury
    decide the case solely on the basis of the evidence
    presented and the court’s instructions on the law is
    subsumed under the right to a fair and impartial jury.
    See State v. Rodriguez, supra, 
    210 Conn. 325
    ; see also
    Hughes v. Borg, 
    supra,
     
    898 F.2d 700
    . Although we agree
    that, in light of the term’s common meaning and in the
    absence of any context suggesting a different meaning,
    a juror likely would interpret a question asking about
    their ability to be impartial as one inquiring about any
    bias they might have against the defendant,22 we are
    satisfied that the trial court ascribed the proper, broader
    meaning to the term. The trial court’s questions were
    not limited to those concerning impartiality but specifi-
    cally concerned whether a dictionary definition of man-
    slaughter had been consulted or raised, whether any
    outside information had affected the jurors’ ability to
    follow the court’s instructions, and whether the jurors
    considered only the evidence presented and the court’s
    instructions. It is apparent, therefore, that the trial court
    used the term impartiality to encompass those critical
    questions.
    We agree with the defendant that, when jurors have
    improperly consulted a dictionary to obtain a definition
    of a legal term, the ultimate inquiry is whether there is
    ‘‘a [reasonable] possibility that the extrinsic material
    could have affected the verdict.’’ (Internal quotation
    marks omitted.) United States v. Steele, 
    supra,
     
    785 F.2d 746
    ; see United States v. Weiss,

    Cir.), cert. denied,

    ,

    ,

    ;

    ; see also State v.
    Rhodes, 
    248 Conn. 39
    , 49 n.16, 
    726 A.2d 513
     (1999) (‘‘the
    critical consideration . . . is not whether prejudice
    may be assumed from [exposure to such information],
    but, rather, whether, under the specific facts of the
    case, any such impropriety actually affected the ver-
    dict’’). The trial court effectively concluded in the pres-
    ent case that no such possibility existed when it found
    that J.B. credibly testified that he had relied on only
    the trial court’s instruction defining manslaughter and
    that the dictionary definition of manslaughter did not
    influence his decision in the case.
    The defendant challenges the propriety of this conclu-
    sion but does so on the basis of the record, not as a
    matter of law.23 Specifically, the defendant argues that
    the trial court could not properly credit J.B.’s ultimate
    answers because there was other evidence indicating
    that J.B. in fact did rely on the dictionary definition of
    manslaughter in the jury deliberations: J.B. recalled the
    dictionary definition more than one month after trial;
    he initially gave equivocal responses to the court’s ques-
    tions about relying on the dictionary and only gave the
    ‘‘ ‘right’ ’’ answers after the court steered him in that
    direction; and his conduct had been sufficiently egre-
    gious that, weeks later, another juror reported to court
    staff that a juror had consulted an outside dictionary
    during deliberations. The defendant further argues that,
    because the court could not properly credit J.B.’s
    responses indicating that he did not rely on the diction-
    ary definition of manslaughter, the court also could
    not assume that J.B.’s arguments to other jurors were
    unaffected by this taint. Because the trial court is not
    permitted to ask the other jurors questions that would
    gauge the influence of J.B.’s arguments on them, the
    defendant asserts that the court was required to con-
    sider how a typical, hypothetical juror would be affected
    by the difference between the definitions. See footnote
    17 of this opinion (setting forth tests identified by defen-
    dant).
    We conclude that, although perhaps the trial court
    reasonably could have drawn the inferences advanced
    by the defendant, it was not compelled to do so. ‘‘[T]he
    trial judge is uniquely qualified to appraise the probable
    effect of information on the jury, the materiality of the
    extraneous material, and its prejudicial nature.’’ (Inter-
    nal quotation marks omitted.) State v. Rodriguez, supra,
    
    210 Conn. 331
    . This court must defer to the credibility
    assessment of the trial court, which has had the oppor-
    tunity to observe first hand each juror’s demeanor and
    attitude and, therefore, is in the best position to judge
    his or her credibility and draw inferences therefrom.
    See State v. Dixon, supra, 
    318 Conn. 506
    . The testimony
    of the jurors that each was, or would be, fair and impar-
    tial, although not determinative, is significant, and ‘‘[we]
    are not inclined to disregard the statements of those
    jurors . . . as inevitably suspect.’’ (Internal quotation
    marks omitted.) State v. Rodriguez, supra, 330; see also
    United States v. Gillespie, 
    61 F.3d 457
    , 460 (6th Cir.
    1995) (‘‘[T]he court should determine whether the jury
    actually used the dictionary definition to reach [its]
    verdict. . . . [A] juror’s declaration at the hearing
    exploring these questions is not inherently suspect.’’).
    No doubt ‘‘[t]he nature and quality of the juror’s assur-
    ances is of paramount importance; the juror must be
    unequivocal about his or her ability to be fair and impar-
    tial.’’ (Internal quotation marks omitted.) State v. Ber-
    rios, supra, 
    320 Conn. 296
    . Although this court may
    review the transcript to ascertain whether it reveals
    textual evidence of equivocation, ‘‘[e]valuation of any
    equivocation evinced in tone or manner remains in the
    province of the trial judge.’’ 
    Id.,
     296–97.
    Some of J.B.’s responses could be viewed as equivo-
    cal or nonresponsive. Part of the problem in characteriz-
    ing those responses is J.B.’s repeated efforts to interject
    his thoughts about the case and tentative votes by the
    jury—both of which were forbidden matters that the
    trial court was assiduously attempting to avoid. The
    trial court, therefore, reasonably attempted to secure
    unequivocal answers to its questions.
    In State v. Berrios, supra, 
    320 Conn. 265
    , in which
    we applied a presumption of prejudice to a third party’s
    improper contact with a juror midtrial; 
    id., 294
    ; we
    concluded that the trial court did not abuse its discre-
    tion in denying the defendant’s motion for a mistrial
    because the state had proved that this contact was
    harmless beyond a reasonable doubt through the jurors’
    testimonial assurances that the impermissible contact
    did not affect their impartiality or their ability to decide
    the case based solely on the evidence admitted at trial.
    
    Id., 296
    . We observed that the trial court’s discretion
    to credit these assurances was reasonable because the
    jurors’ testimony was unequivocal and supported by
    other facts in the record.24 See 
    id.,
     296–99.
    Stricter scrutiny may be warranted when jurors are
    asked postverdict whether they acted impartially and
    in accordance with the court’s instructions, especially
    when the question is posed to a juror who has commit-
    ted misconduct. See State v. Dixon, supra, 
    318 Conn. 507
     (‘‘[t]he trial court’s assessment of the juror’s assur-
    ances, [although] entitled to deference, must be realistic
    and informed by inquiries adequate in the context of the
    case to ascertain the nature and import of any potential
    juror bias’’ (internal quotation marks omitted)); see
    also, e.g., State v. Holt, 
    79 S.D. 50
    , 53, 
    107 N.W.2d 732
    (1961) (trial court properly relied on jurors’ affidavits
    stating that their use of dictionary for terms relevant
    to lesser included offenses did not influence their ver-
    dict to overcome presumption of prejudice given that
    verdict on principal charge eliminated consideration of
    lesser included offenses). In the present case, the trial
    court’s conclusion is bolstered by the fact that the mis-
    conduct occurred before the court specifically directed
    the jury not to consult the dictionary and to rely exclu-
    sively on the elements in the court’s manslaughter
    instruction. The court’s initial charge to the jury did not
    include such a pointed instruction, and it is reasonably
    possible that J.B. did not recall the court’s specific
    prohibition on consulting dictionaries from jury selec-
    tion approximately one month earlier. See footnote 11
    of this opinion. The fact that other jurors sent the note
    to the court to shut down any further efforts by J.B.
    to discuss the dictionary definition suggests that they
    would have alerted the court, before the verdict was
    rendered, if J.B.’s comments suggested that he contin-
    ued to rely on the dictionary definition after the court
    responded to the note. The jury deliberated until the day
    after the court responded to the note, without further
    incident. Cf. Jordan v. Brantley, 
    589 So. 2d 680
    , 682
    (Ala. 1991) (‘‘[t]he evidence reflects that the jury had
    not been able to reach a verdict until the dictionary
    was used’’). Under these circumstances, it is reasonable
    to presume that the jurors followed the court’s instruc-
    tions. See, e.g., State v. Rodriguez, supra, 
    210 Conn. 333
     (‘‘[t]he jury, in the absence of a fair indication to
    the contrary, is presumed to have followed the instruc-
    tions of the court’’ (internal quotation marks omitted)).
    The trial court correctly concluded that the juror
    misconduct caused no actual prejudice to the defen-
    dant. The record clearly establishes that there was no
    reasonable possibility that any member of the jury relied
    on the dictionary definition to the defendant’s detriment
    in reaching the verdict. The state proved that the mis-
    conduct was harmless beyond a reasonable doubt. The
    trial court therefore properly denied the defendant’s
    motion for a new trial.25
    The judgment is affirmed.
    In this opinion the other justices concurred.
    * November 23, 2021, the date that this decision was released as a slip
    opinion, is the operative date for all substantive and procedural purposes.
    1
    The defendant appealed directly to this court pursuant to General Stat-
    utes § 51-199 (b) (3).
    2
    The defendant does not challenge his conviction of criminal possession
    of a firearm. We therefore limit the facts to those relevant to the manslaughter
    conviction.
    3
    An autopsy performed by a state medical examiner revealed that the
    victim sustained three gunshot wounds: to his left shoulder, to his left leg,
    and to his torso, in the abdominal area. The bullets that caused the shoulder
    and leg wounds entered the victim’s body from the back. The sequence of
    the gunshots could not be determined.
    4
    ‘‘[A] person is not justified in using deadly physical force upon another
    person if he or she knows that he or she can avoid the necessity of using
    such force with complete safety . . . by retreating . . . .’’ General Statutes
    § 53a-19 (b) (1).
    5
    In order to prevail on an unpreserved claim, a defendant must show that
    (1) the record is adequate to review the alleged claim of error, (2) the claim
    is of constitutional magnitude alleging the violation of a fundamental right,
    (3) the alleged constitutional violation exists and deprived the defendant
    of a fair trial, and (4) if the claim is subject to harmless error analysis, the
    state has failed to demonstrate harmlessness beyond a reasonable doubt.
    See, e.g., In re Yasiel R., supra, 
    317 Conn. 779
    , 781. A claim is reviewable
    if the first two prongs are met; the second two prongs involve a determination
    of whether the defendant may prevail. See 
    id.,
     779 n.6.
    6
    Although our case law typically states this subjective-objective frame-
    work in connection with challenges to the second requirement regarding
    the degree of force necessary to respond; see, e.g., State v. O’Bryan, supra,
    
    318 Conn. 632
    ; State v. Saunders, 
    267 Conn. 363
    , 373, 
    838 A.2d 186
    , cert.
    denied, 
    541 U.S. 1036
    , 
    124 S. Ct. 2113
    , 
    158 L. Ed. 2d 722
     (2004); State v.
    Clark, supra, 
    264 Conn. 732
    ; the fact that both requirements are premised
    on a reasonable belief makes this framework equally applicable to the first
    requirement, which is the focus of the parties’ arguments in the present
    case. See Burke v. Mesniaeff, 
    334 Conn. 100
    , 128, 
    220 A.3d 777
     (2019).
    7
    Although the self-defense statute also permits this defense when the
    defendant reasonably believes that he is at risk of great bodily harm; see
    General Statutes § 53a-19 (a) (2); the defendant’s theory in the present case
    is that he believed that the victim was drawing a gun.
    8
    Although the availability of the defense of self-defense does not depend
    on whether the victim was in fact using or about to use deadly physical
    force because it is the defendant’s belief that is material; see, e.g., State v.
    Clark, supra, 
    264 Conn. 732
    ; the presence of a weapon would lend support
    to the defendant’s belief.
    9
    Knight was not a particularly helpful witness to either side. The police
    interviewed her on two occasions. Both interviews were video-recorded. In
    the first interview, which took place a few hours after the incident in ques-
    tion, Knight stated that she knew nothing about what had happened and
    that she was alone in the Armada until she tried to leave the pub’s parking
    lot. The second interview took place a few days later, after she was charged
    with interfering with the police investigation. Knight acknowledged that she
    had been less than truthful during the first interview. When Knight testified
    at trial, her recollection of the events at issue was poor, and the state
    introduced portions of both of her video-recorded statements to the police
    as prior inconsistent statements under State v. Whelan, 
    200 Conn. 743
    , 753,
    
    513 A.2d 86
    , cert. denied, 
    479 U.S. 994
    , 
    107 S. Ct. 597
    , 
    93 L. Ed. 2d 598
     (1986).
    10
    The court also instructed the jury that the state was required to prove
    that the defendant used a firearm to cause the victim’s death. See General
    Statutes § 53a-55a.
    11
    At the commencement of jury selection, the court provided the following
    admonishment to prospective jurors: ‘‘Please do not do any legal research
    into any of the issues involved in this case. Please don’t look up anything
    on the Internet, any terms in the dictionary, review any medical textbooks
    or look up the statutes which might be at issue here. . . . I will instruct
    you as to the definitions of any terms you need to know, and the lawyers
    will elicit from the witnesses any explanations of terms or principles which
    the lawyers believe will be necessary in your deliberations.’’ In its instruc-
    tions at the commencement of trial two weeks later, the court also admon-
    ished the jury that ‘‘[i]t is your duty to accept the law and to follow it as I
    give it to you, whether or not you agree with it.’’
    12
    Although the jury’s note reasonably may have been interpreted to imply
    that no juror had yet consulted a dictionary, the present case demonstrates
    that the better practice under these circumstances would be for the trial
    court to conduct an inquiry to confirm that no such action had been taken.
    Had the court done so in the present case, it could have considered whether
    to excuse the juror who had in fact already consulted the dictionary and
    to replace him with an alternate juror. See, e.g., State v. Klafta, 
    73 Haw. 109
    , 123, 
    831 P.2d 512
     (1992).
    13
    The jurors are referred to by their initials to protect their privacy inter-
    ests. See, e.g., State v. Osimanti, 
    299 Conn. 1
    , 30 n.28, 
    6 A.3d 790
     (2010).
    14
    When a trial court is presented with allegations of juror misconduct in
    a criminal case, it must conduct, on the record, an inquiry into the allegations.
    See State v. Brown, 
    235 Conn. 502
    , 526, 
    668 A.2d 1288
     (1995). The nature
    of such an inquiry lies within the trial court’s discretion and may vary from
    a preliminary inquiry of counsel to a full evidentiary hearing. See id., 529.
    If the court determines that an evidentiary hearing is warranted, it has wide
    discretion in deciding how to conduct the hearing to determine the nature
    and effect of information that comes to a juror improperly and its potential
    effect on the entire jury if it learns of it. See id. There is no claim in the
    present case that the procedure was in any way deficient or improper.
    15
    We have omitted J.B.’s comments that reveal aspects of his, or any other
    juror’s, deliberative process. The trial court’s questions clearly were not
    aimed at eliciting such information, and the trial court properly disregarded
    any such statements in its decision on the defendant’s motion. See Aillon
    v. State, 
    168 Conn. 541
    , 551–52, 
    363 A.2d 49
     (1975); see also Practice Book
    § 42-33.
    16
    It is unclear what the trial court meant by this comment. Nonetheless,
    as we explain in this opinion; see footnote 25 of this opinion; the differences
    in the definitions could not have prejudiced the defendant under the circum-
    stances of the present case.
    17
    The defendant identifies three tests applicable to the present circum-
    stances, which he characterizes as follows: (1) a ‘‘[d]efinitional’’ test, which
    compares the statutory requirement or legal definition provided by the trial
    court to the dictionary definition and assesses whether application of the
    dictionary definition could have been harmful to the defendant; see, e.g.,
    Commonwealth v. Wood, 
    230 S.W.3d 331
    , 333–34 (Ky. App. 2007); State v.
    Abell, 
    383 N.W.2d 810
    , 812–13 (N.D. 1986); (2) a ‘‘typical juror’’ test, which,
    in recognition of the fact that the trial court is precluded from eliciting
    evidence regarding the actual effect of the extrinsic information on the
    jurors, applies an objective, multifactor test to determine whether there is
    a reasonable possibility that the extrinsic information influenced the verdict
    to the defendant’s detriment; see, e.g., People v. Harlan, 
    109 P.3d 616
    , 625–26
    (Colo.), cert. denied, 
    546 U.S. 928
    , 
    126 S. Ct. 399
    , 
    163 L. Ed. 2d 277
     (2005);
    and (3) the ‘‘Mayhue’’ test; see Mayhue v. St. Francis Hospital of Wichita,
    Inc., 
    969 F.2d 919
     (10th Cir. 1992), which sets forth a multifactor, nonexclu-
    sive test to assess prejudice from jurors’ use of dictionary definitions. 
    Id., 924
    ; see also United States v. Lawson, 
    677 F.3d 629
    , 646–51 (4th Cir.)
    (applying Mayhue factors), cert. denied sub nom. Hutto v. United States,
    
    568 U.S. 889
    , 
    133 S. Ct. 393
    , 
    184 L. Ed. 2d 162
     (2012).
    Although this court previously has indicated that the effect of juror miscon-
    duct or external influences would be assessed under an objective test; see
    Sawicki v. New Britain General Hospital, 
    302 Conn. 514
    , 523–24, 
    29 A.3d 453
     (2011); State v. Johnson, 
    supra,
     
    288 Conn. 263
     n.26; see also State v.
    Berrios, 
    320 Conn. 265
    , 287 and n.20, 
    129 A.3d 696
     (2016) (citing with
    approval objective standard of Second Circuit Court of Appeals); we have
    not yet had occasion to adopt any particular test.
    18
    Because we conclude that the trial court properly relied on the jurors’
    testimony, we need not consider whether the defendant is entitled to review
    of his claim regarding the various objective tests he proposes. Insofar as
    the state suggests that the defendant is not entitled to review of his claim
    that the trial court improperly placed the burden of proof on him, we see
    no preservation problem in light of the state’s concession before the trial
    court that it had the burden of proof.
    19
    Although we apply a presumption that the trial court properly allocated
    the burden of proof when the court’s decision is silent on that matter; see
    Bisson v. Wal-Mart Stores, Inc., 
    184 Conn. App. 619
    , 630 n.11, 
    195 A.3d 707
    (2018); the decision in the present case has statements that appear to conflict
    on this matter without resolving that conflict. We acknowledge that these
    ambiguities in the trial court’s decision are a reflection of a lack of clarity
    in our own case law. The trial court quoted this court’s case law stating
    that, ‘‘[i]f . . . the trial court is not at fault for the alleged juror misconduct
    . . . [the] defendant . . . bears the burden of proving that actual prejudice
    resulted from the misconduct’’; (internal quotation marks omitted) State v.
    Roman, 
    320 Conn. 400
    , 409, 
    133 A.3d 441
     (2016); as well as case law stating
    that ‘‘[c]onsideration of extrinsic evidence is presumptively prejudicial
    . . . .’’ State v. Asherman, supra, 
    193 Conn. 736
    .
    20
    We underscore that the court’s decision potentially could satisfy either
    standard because it rested on evidence that the court credited, not the
    defendant’s failure to present evidence.
    21
    This is not to say that courts have uniformly approached this issue.
    Some courts distinguish extrinsic information that may be relied on to decide
    the facts of the case from information that implicates the law in the case.
    Compare United States v. Cheyenne, 
    855 F.2d 566
    , 568 (8th Cir. 1988) (factual
    and legal information do not raise same concerns), with United States v.
    Lawson, 
    677 F.3d 629
    , 645–46 (4th Cir.) (many of same concerns arise when
    juror uses dictionary as when juror consults with third party), cert. denied
    sub nom. Hutto v. United States, 
    568 U.S. 889
    , 
    133 S. Ct. 393
    , 
    184 L. Ed. 2d 162
     (2012). Some courts distinguish between information obtained from a
    ‘‘standard’’ dictionary, deeming it reflective of common meaning that jurors
    may be presumed to know and thus not extrinsic information, and informa-
    tion obtained from a legal dictionary. See, e.g., Rutland v. State, 
    60 So. 3d 137
    , 144 (Miss. 2011); see also Ryser v. State, supra, 
    453 S.W.3d 41
    .
    22
    See, e.g., American Heritage College Dictionary (4th Ed. 2007) p. 694
    (defining ‘‘impartial’’ to mean ‘‘[n]ot partial or biased; unprejudiced’’).
    23
    It is significant that the defendant does not contend either that the trial
    court should not have inquired about whether the jurors used the dictionary
    definition (i.e., outside information) in their deliberations or that negative
    responses to such inquiries are per se an improper consideration. See State
    v. Suschank, 
    595 S.W.2d 295
    , 298 (Mo. App. 1979) (because defendant did
    not object to questioning of jury after verdict, trial court could properly
    consider testimony of jurors in determining prejudicial effect of use of
    dictionary). Some jurisdictions do not permit the trial court to inquire
    whether the jurors actually relied on the definition in deciding the case,
    viewing such questions as intruding on the deliberative process. See, e.g.,
    State v. Duncan, 
    3 Kan. App. 2d 271
    , 275, 
    593 P.2d 427
     (1979) (‘‘[i]t is not
    permissible to inquire whether . . . the dictionary definition of ‘assault’
    was given weight by the jury’’); Commonwealth v. Wood, 
    230 S.W.3d 331
    ,
    333 (Ky. App. 2007) (court should consider juror testimony concerning any
    overt acts of misconduct but not ‘‘secret thoughts of jurors’’). In such cases,
    the court would proceed to an objective inquiry as to whether consideration
    of the definition would affect the verdict of a typical juror.
    24
    The testimony adduced at the hearing in Berrios established that the
    defendant’s mother had approached one of the jurors during a recess from
    presentation of evidence, that she had made a negative comment about the
    truthfulness of one of the state’s witnesses, and that all of the jurors became
    aware of that contact. See State v. Berrios, supra, 
    320 Conn. 269
    –70. The
    trial court rejected the defendant’s suggestion that the impropriety was
    extraordinarily prejudicial because it could lead jurors to suspect that the
    defendant had instigated the jury tampering and had done so in an effort
    to cause a mistrial, which would cause the jurors to regard him unfavorably
    in their deliberations. 
    Id., 277, 299
    . In concluding that the trial court properly
    could credit the jurors’ assurances that they could be impartial despite the
    improper contact, we pointed to the fact that J, the juror who was
    approached by the defendant’s mother, had reported the incident to the
    court, whereas, ‘‘[h]ad the actions of the defendant’s mother left [J] inclined
    to be less than fair and impartial toward the defendant, [J] likely would have
    kept that information to himself in an attempt to ensure that he remained
    on the jury to vote to convict the defendant.’’ (Internal quotation marks
    omitted.) 
    Id.,
     297–98. We also noted that, because jurors J and L had
    expressed understanding for the actions of the defendant’s mother, given
    her obvious concern for the defendant’s future, such expressions supported
    the trial court’s determination that the jurors were not biased against the
    defendant as a result of his mother’s actions. 
    Id., 298
    .
    25
    We note that the defendant would not be entitled to a new trial even
    if the trial court should have discounted the jurors’ assurances. See United
    States v. Chanthadara, 
    230 F.3d 1237
    , 1251 (10th Cir. 2000) (‘‘prejudice
    presumed, even if not cured by subsequent instructions and juror assurances
    of impartiality, may be proven harmless if the government can establish
    there was overwhelming evidence of the defendant’s guilt’’), cert. denied,
    
    534 U.S. 992
    , 
    122 S. Ct. 457
    , 
    151 L. Ed. 2d 376
     (2001). The defendant’s
    complaint is that the dictionary definition of manslaughter omitted two
    elements of the statutory definition—that he must have acted recklessly
    and under circumstances evincing an extreme indifference to human life. See
    General Statutes § 53a-55 (a) (3). These elements, however, were effectively
    uncontested. It was undisputed that the defendant fired his gun multiple
    times at the victim in a dark parking lot where others were present. Defense
    counsel conceded during his closing argument that the jury could find the
    defendant guilty of either murder or manslaughter but that such a finding
    was immaterial because the state could not prove that he had not acted in
    self-defense. See State v. Singleton, 
    292 Conn. 734
    , 749, 
    974 A.2d 679
     (2009)
    (‘‘self-defense is a justification for engaging in otherwise criminal conduct’’
    (emphasis omitted; internal quotation marks omitted)). The defendant can-
    not, therefore, establish prejudice. See, e.g., United States v. Cheyenne, 
    855 F.2d 566
    , 568 (8th Cir. 1988) (no prejudice when dictionary definition was
    not relevant to only disputed issue); State v. Duncan, 
    3 Kan. App. 2d 271
    ,
    275, 
    593 P.2d 427
     (1979) (‘‘[w]e agree that the difference in definitions is
    substantial, but the evidence of [the] defendant’s guilt of aggravated assault
    . . . was overwhelming if not irrefutable’’); cf. State v. Padua, 
    273 Conn. 138
    , 167, 
    869 A.2d 192
     (2005) (‘‘a jury instruction that improperly omits an
    essential element from the charge constitutes harmless error if a reviewing
    court concludes beyond a reasonable doubt that the omitted element was
    uncontested and supported by overwhelming evidence, such that the jury
    verdict would have been the same absent the error’’ (emphasis omitted;
    internal quotation marks omitted)).
