    STATE OF CONNECTICUT v. JOHN
    MARSHALL SPENCE
    (AC 36471)

    Opinion
    ALVORD, J. The defendant, John Marshall Spence,
    appeals from the trial court’s judgment of conviction,
    rendered after a jury trial, of possession of child pornog-
    raphy in the first degree in violation of General Statutes
    § 53a-196d (a) (1).1 On appeal, the defendant claims that
    the trial court committed error by (1) ‘‘denying the
    defendant’s motion to suppress his statements’’ made
    to the police prior to his formal arrest; (2) ‘‘giving a
    constructive possession instruction that treated a com-
    puter as the equivalent of a premises’’; and (3) ‘‘permit-
    ting the state to offer rebuttal evidence on matters that
    it knew were at issue during the case-in-chief.’’ We
    affirm the judgment of the trial court.
    The following facts, which the jury reasonably could
    have found, and procedural history are relevant to this
    appeal. The state police began investigating the defen-
    dant’s activities when they received a tip that a person
    with a Connecticut Internet protocol (IP) address was
    downloading child pornography over peer-to-peer file
    sharing networks.2 Using a computer program tailored
    for law enforcement, the state police accessed the iden-
    tified IP address and downloaded images of child por-
    nography. The state police applied for and were granted
    an ex parte order to require the Internet service provider
    to reveal the name and street address associated with
    the identified IP address. The state police then obtained
    a search warrant for the defendant’s home.
    On June 13, 2012, state troopers and local police
    executed a search and seizure warrant at the defen-
    dant’s home at 34 May Street in Fairfield. Police entered
    the home shortly after 6 a.m. and found the defendant,
    his wife, three children, and mother-in-law in the single
    family residence. At that time, the lead investigator,
    state police Detective David Aresco, asked the defen-
    dant if he could explain why the state police were in
    his home. In response, the defendant asked if ‘‘he could
    speak with Detective Aresco in private.’’ Once outside,
    the defendant received a Miranda warning and then
    provided an oral and written statement acknowledging
    that he had downloaded more than 150 images and
    videos of child pornography and that he had exclusive
    control of the computer where the files were stored.
    Before the defendant’s trial began, he moved to sup-
    press the statements he made to the state police on the
    day his home was searched. On September 6, 2013, the
    trial court conducted a hearing on the motion. Ulti-
    mately, the trial court denied the motion and the defen-
    dant was convicted by a jury of possession of child
    pornography in the first degree. This appeal followed.
    Additional facts will be set forth as necessary.
    I
    The defendant claims on appeal that the trial court
    improperly denied his motion to suppress his state-
    ments to the police on the day the search warrant was
    executed at his home. Specifically, the defendant argues
    that when the police entered his home and gathered
    together the residents in one room, based on the circum-
    stances, a reasonable person in his situation would
    believe he was in custody. Accordingly, he claims that
    the police should have provided a Miranda warning
    before they asked any questions. Prior to trial, the defen-
    dant sought to suppress his initial response to Detective
    Aresco asking if he could speak to the detective ‘‘in
    private.’’ He also sought to suppress the oral and written
    statements he made after receiving Miranda warnings.
    The defendant argued that the lack of a Miranda warn-
    ing prior to his initial request to speak with the police
    in private tainted the statements that followed. We con-
    clude that the trial court did not err by denying the
    motion to suppress and allowing the statements to be
    admitted as evidence.
    The following additional facts that the trial court
    reasonably could have found are relevant to the defen-
    dant’s claim. The search warrant was executed at the
    defendant’s home at approximately 6:10 a.m. on June
    13, 2012. Eight to ten state troopers and police officers
    entered the home. The officers were wearing standard
    issue side arms, bulletproof vests, and clothes that iden-
    tified that they were law enforcement. The defendant
    was sleeping on the second floor when the police
    arrived. After the police conducted a protective sweep
    of the rooms in the home, they gathered the entire
    family into the kitchen or dining room area. Without
    issuing a Miranda warning, Aresco informed the resi-
    dents that he was investigating a computer crime and
    then asked the defendant if he could explain why the
    police were in his home. The defendant responded by
    asking if they could speak in private. The defendant
    therefore was brought outside to an unmarked police
    car. He was advised of his Miranda rights and signed
    a waiver notice to confirm that he was aware of his
    rights. The defendant was questioned and Aresco
    recorded notes and prepared a written statement. The
    three page written statement was read back to the
    defendant. After rereading it and making corrections,
    the defendant signed the statement and initialed each
    page. The questioning lasted for approximately one and
    one-half hours and the defendant was allowed to take
    a cigarette break. The court held a hearing on the
    motion to suppress that included testimony from Are-
    sco and another state trooper who was involved with
    the execution of the search warrant at the defendant’s
    home. The court denied the defendant’s motion after
    concluding that the defendant was not in custody when
    he initially responded to Aresco’s inquiry.
    ‘‘[O]ur standard of review of a trial court’s findings
    and conclusions in connection with a motion to sup-
    press is well defined. A finding of fact will not be dis-
    turbed unless it is clearly erroneous in view of the
    evidence and pleadings in the whole record . . . .
    [When] the legal conclusions of the court are chal-
    lenged, we must determine whether they are legally and
    logically correct and whether they find support in the
    facts set out in the memorandum of decision . . . .’’

    We first consider whether the court properly found
    that the defendant was not in custody at the time the
    statements in issue were made. ‘‘In order to determine
    the [factual] issue of custody, however, we will conduct
    a scrupulous examination of the record . . . in order
    to ascertain whether, in light of the totality of the cir-
    cumstances, the trial court’s finding is supported by
    substantial evidence. . . . The ultimate inquiry as to
    whether, in light of these factual circumstances, a rea-
    sonable person in the defendant’s position would
    believe that he or she was in police custody of the
    degree associated with a formal arrest . . . calls for
    application of the controlling legal standard to the his-
    torical facts [and] . . . therefore, presents a . . .
    question of law . . . over which our review is de novo.
    . . . In other words, we are bound to accept the factual
    findings of the trial court unless they are clearly errone-
    ous, but we exercise plenary review over the ultimate
    issue of custody.’’ (Citation omitted; internal quotation

    311 Conn. 182
    , 197,
    
    85 A.3d 627
     (2014).
    ‘‘[T]he Fifth Amendment privilege [against self-
    incrimination] is available outside of criminal court pro-
    ceedings and serves to protect persons in all settings
    in which their freedom of action is curtailed in any
    significant way from being compelled to incriminate
    themselves. We have concluded that without proper
    safeguards the process of in-custody interrogation of
    persons suspected or accused of crime contains inher-
    ently compelling pressures which work to undermine
    the individual’s will to resist and to compel him to speak
    where he would not otherwise do so freely.’’ Miranda

    , 
    16 L. Ed. 2d 694
     (1966). ‘‘Two threshold conditions must be
    satisfied in order to invoke the warnings constitution-
    ally required by Miranda: (1) the defendant must have
    been in custody; and (2) the defendant must have been
    subjected to police interrogation. . . . [A]lthough the
    circumstances of each case must certainly influence a
    determination of whether a suspect is in custody for
    purposes of receiving Miranda protection, the ultimate
    inquiry is simply whether there is a formal arrest or
    restraint on freedom of movement of the degree associ-
    ated with a formal arrest.’’ (Internal quotation marks

    304 Conn. 383
    , 416, 
    40 A.3d 290
     (2012).
    ‘‘As used in . . . Miranda [and its progeny], custody
    is a term of art that specifies circumstances that are
    thought generally to present a serious danger of coer-
    cion. . . . In determining whether a person is in cus-
    tody in this sense . . . the United States Supreme
    Court has adopted an objective, reasonable person test
    . . . the initial step [of which] is to ascertain whether,
    in light of the objective circumstances of the interroga-
    tion . . . a reasonable person [would] have felt [that]
    he or she was not at liberty to terminate the interroga-
    tion and [to] leave.’’ (Citations omitted; internal quota-
    tion marks omitted.) State v. Mangual, supra, 
    311 Conn. 193
    .
    ‘‘[N]ot all restrictions on a suspect’s freedom of action
    rise to the level of custody for Miranda purposes; in
    other words, the freedom-of-movement test identifies
    only a necessary and not a sufficient condition for
    Miranda custody. . . . Rather, the ultimate inquiry is
    whether a reasonable person in the defendant’s position
    would believe that there was a restraint on [her] free-
    dom of movement of the degree associated with a for-
    mal arrest. . . . Any lesser restriction on a person’s
    freedom of action is not significant enough to implicate
    the core fifth amendment concerns that Miranda
    sought to address.’’ (Citations omitted; footnote omit-
    ted; internal quotation marks omitted.)

    After reviewing state and federal cases concerning
    custody, our Supreme Court compiled a nonexclusive
    ‘‘list of factors to be considered in determining whether
    a suspect was in custody for purposes of Miranda [in
    circumstances involving the interrogation of a suspect
    during a police search of his residence]: (1) the nature,
    extent and duration of the questioning; (2) whether
    the suspect was handcuffed or otherwise physically
    restrained; (3) whether officers explained that the sus-
    pect was free to leave or not under arrest; (4) who
    initiated the encounter; (5) the location of the interview;
    (6) the length of the detention; (7) the number of offi-
    cers in the immediate vicinity of the questioning; (8)
    whether the officers were armed; (9) whether the offi-
    cers displayed their weapons or used force of any other
    kind before or during questioning; and (10) the degree
    to which the suspect was isolated from friends, family
    and the public.’’ 
    Id., 197
    .
    A
    An application of the factors enumerated in Mangual
    to the facts of this case informs our conclusion that
    the trial court properly concluded that a reasonable
    person in the defendant’s position would not have
    believed that he was in police custody of the degree
    associated with a formal arrest. On the basis of the
    facts that the trial court reasonably could have found,
    the police presence did not overwhelm the defendant
    to the point that a reasonable person would believe
    that he was in custody.
    Any questioning that occurred in the defendant’s
    home was informal in nature and short in duration.
    Aresco advanced a general question that introduced his
    presence in the home. The defendant did not answer
    the question. Instead, he effectively put off any discus-
    sion by requesting to speak with the investigators in
    private. While inside the home, the defendant was not
    handcuffed or restrained. The surroundings were famil-
    iar to the defendant. He was in an open area of the
    home, and he was surrounded by his family including
    other adults. While there were as many as ten police
    officers in the home assisting with the execution of the
    search warrant, they were not brandishing their
    weapons.
    Considering the totality of the circumstances, the trial
    court properly determined that the defendant was not
    in custody and therefore a Miranda warning was not
    required. We do note that Aresco did initiate the ques-
    tioning and the defendant was not informed by police
    that he was free to leave. These two Mangual factors
    weigh in favor of a custodial environment, however, a
    consideration of the remaining factors applied to this
    case compels the conclusion that a reasonable person
    in the defendant’s position would not have believed
    that he was in police custody of the degree associated
    with formal arrest.
    The circumstances in this case did not create the
    police dominated atmosphere that existed in Mangual.
    In that case our Supreme Court determined that when
    police officers conducted a drug raid by brandishing
    handguns and rifles in a small apartment, they created
    a police dominated atmosphere that would cause a rea-
    sonable person to believe that he was in police custody
    even though there had not been a formal arrest.3 State
    v. Mangual, supra, 
    311 Conn. 199
    –202. Here, the officers
    in the defendant’s home were not brandishing weapons.
    A similar number of law enforcement officers were
    present here as in Mangual, however, that case involved
    a small apartment whereas this was a residential home.
    See 
    id., 201
    . Finally, the questioning in Mangual was
    more extensive; there the defendant and her daughters
    were confined to a couch and there were no other adults
    present. See 
    id.,
     186–87, 201–202. The police dominated
    atmosphere described in Mangual was not present in
    this case. Therefore, no Miranda warning was required.
    B
    The defendant also claims that the trial court should
    have suppressed the statements he made to police after
    he received and acknowledged a Miranda warning. The
    defendant argues that the Mirandized interrogation
    was tainted by the alleged unconstitutional questioning
    that occurred in his home because it was a continuation
    of the same event. Because we already have determined
    that during the interaction in the home a reasonable
    person in the defendant’s position would not have
    believed that he was in police custody of the degree
    associated with formal arrest, the defendant’s argument
    for suppressing the subsequent Mirandized statement
    fails. The record shows that the defendant received a
    Miranda warning before he gave his full statement to
    Aresco and another trooper in their police car. The
    defendant has not proffered any other evidence to sug-
    gest that the defendant’s waiver of his right to remain
    silent was involuntary. The trial court’s denial of the
    defendant’s motion to suppress was legally and logically
    correct and supported by the facts set out in the memo-
    randum of decision. We conclude that the trial court
    properly denied the motion to suppress the defen-
    dant’s statements.
    II
    The defendant also claims on appeal that the trial
    court erroneously instructed the jury on constructive
    possession. The trial court instructed the jury that it
    could infer that the defendant possessed the images of
    child pornography if it found that the defendant had
    control of the computer that contained the images. The
    defendant argues that the trial court was required to
    instruct the jury that it could infer possession of pornog-
    raphy only if it found that the defendant had control
    over the computer and the premises within which it
    was found. We disagree. The trial court was not required
    to include an instruction regarding control of the prem-
    ises. Moreover, it was not reasonably possible that the
    jury was misled by the court’s instruction.
    The following additional facts are relevant to the
    defendant’s claim. During the course of the trial, Detec-
    tive Aresco testified that one computer was removed
    from the defendant’s home as a result of the execution
    of the search warrant on June 13, 2012. The computer
    was found in the defendant’s bedroom, and he told
    police that he kept it under his bed. The defendant lived
    in the home with his wife, three children, and his wife’s
    parents. Aresco testified that other computers also were
    found in the home and examined for child pornography,
    but only the defendant’s computer was found to contain
    the illicit images. In his statement to the state police,
    the defendant stated that his computer was password
    protected and ‘‘I am the only person that has that com-
    puter—that uses that computer.’’
    Prior to the instruction being read to the jury, defense
    counsel objected to the language of the instruction
    because it did not require the jury to find that the defen-
    dant also had exclusive control of the home where the
    computer was located: ‘‘It should be [control over the]
    premises and computer because of the nature of a com-
    puter you can be in exclusive possession of it, yet leave
    it in a common area, and if that common area is not
    exclusively yours, then someone else has access [to]
    it.’’ The trial court overruled the objection.
    At the close of the trial, the court instructed the
    jury regarding constructive possession: ‘‘The state has
    submitted evidence in order to show that the defendant
    had control over the computer where the video files
    were found. Control of the computer gives rise to the
    inference of unlawful possession. And the mere access
    by others is insufficient to defeat this inference. If it is
    proven that the defendant is the exclusive owner of the
    computer where the video files were found, then you
    may infer that he controlled the computer. However,
    when it is shown that ownership or use of the computer
    is not exclusive, you may no longer make this inference.
    The ability to control the computer must be established
    by independent proof.’’ The court also instructed the
    jury that in order to convict the defendant, they were
    required to find beyond a reasonable doubt that he
    ‘‘knowingly possessed the child pornography.’’
    We review instructional impropriety to determine
    ‘‘whether it is reasonably possible that the jury was
    misled. . . . In determining whether the jury was mis-
    led, [i]t is well established that [a] charge to the jury
    is not to be critically dissected for the purpose of dis-
    covering possible inaccuracies of statement, but it is
    to be considered rather as to its probable effect upon
    the jury in guiding [it] to a correct verdict in the case.
    . . . The charge is to be read as a whole and individual
    instructions are not to be judged in artificial isolation
    from the overall charge. . . . The test to be applied to
    any part of a charge is whether the charge, considered
    as a whole, presents the case to the jury so that no
    injustice will result. . . . The charge must be consid-
    ered from the standpoint of its effect on the jury in
    guiding [it] to a proper verdict. . . .
    ‘‘Our review of the defendant’s claim of instructional
    error requires that we examine the court’s entire charge
    to determine whether it was reasonably possible that
    the jury could have been misled by the omission of the
    requested instruction. While a request to charge that is
    relevant to the issues in a case and that accurately
    states the applicable law must be honored, a [trial] court
    need not tailor its charge to the precise letter of such
    a request. . . . As long as [the instructions] are correct
    in law, adapted to the issues and sufficient for the guid-
    ance of the jury . . . we will not view the instructions
    as improper.’’ (Citation omitted; internal quotation
    marks omitted.) State v. Conyers,

    ,
    472–73, 
    127 A.3d 1077
     (2015).
    To be convicted of possession of child pornography
    in the first degree, the jury must find that the defendant
    knowingly possessed the contraband. General Statutes
    § 53a-196d (a) (1). ‘‘Possess, as defined in § 53a-3 (2),
    means to have physical possession or otherwise to exer-
    cise dominion or control over tangible property. . . .
    Our jurisprudence elucidating this definition teaches
    that such possession may be actual or constructive.
    . . . Nevertheless, [b]oth actual and constructive pos-
    session require a person to exercise dominion and con-
    trol over the [contraband] and to have knowledge of
    its presence and character. . . . Actual possession
    requires the defendant to have had direct physical con-
    tact with the [contraband]. . . . Typically, the state
    will proceed under a theory of constructive possession
    when the [contraband is] not found on the defendant’s
    person at the time of arrest, but the accused still exer-
    cises dominion and control. . . . In this regard, [t]he
    essence of exercising control is not the manifestation
    of an act of control but instead it is the act of being in
    a position of control coupled with the requisite mental
    intent. In our criminal statutes involving possession,
    this control must be exercised intentionally and with
    knowledge of the character of the controlled object.’’

    295 Conn. 902
    , 
    988 A.2d 878
     (2010).
    The court’s instruction included an explanation of
    each of the elements the jury had to find present in
    order to convict the defendant of the alleged crime.4
    Finding control of the home in this case is not a require-
    ment to infer possession of the contraband when the
    contraband is contained within another object, here the
    computer, that itself could be controlled and secured
    through the use of a password. ‘‘To mitigate the possibil-
    ity that innocent persons might be prosecuted for . . .
    possessory offenses . . . it is essential that the state’s
    evidence include more than just a temporal and spatial
    nexus between the defendant and the contraband. . . .
    While mere presence is not enough to support an infer-
    ence of dominion or control, where there are other
    pieces of evidence tying the defendant to dominion and
    control, the [finder of fact is] entitled to consider the
    fact of [the defendant’s] presence and to draw infer-
    ences from that presence and the other circumstances
    linking [the defendant] to the crime.’’ (Internal quota-
    tion marks omitted.) State v. Smith,

    , cert. denied, 
    278 Conn. 906
    , 
    897 A.2d 100
     (2006). It was not necessary for the jury to
    find that the defendant controlled the premises in order
    to infer that he possessed the child pornography.
    The court’s failure to include the language regarding
    ‘‘control of the premises’’ could not have reasonably
    misled the jury. The defendant argues that the instruc-
    tion the trial court delivered to the jury improperly
    modified this state’s model instruction by substituting
    ‘‘computer’’ for ‘‘premises.’’ Of course, varying the
    wording of the model instruction does not mean that
    the instruction provided was an incorrect statement of
    the law. Regarding possession, our criminal model jury
    instructions provide in relevant part: ‘‘A complete
    instruction on possession may require explanations of
    constructive possession and nonexclusive possession
    if relevant to the case. Tailor this instruction
    according to the specific allegations of possession.’’

    The court’s instruction was proper because a reason-
    able jury could make a rational conclusion that if the
    defendant had control of the computer, then he had
    possession of its contents. ‘‘[I]t is a function of the jury
    to draw whatever inferences from the evidence or facts
    established by the evidence it deems to be reasonable
    and logical. . . . Because [t]he only kind of an infer-
    ence recognized by the law is a reasonable one . . .
    any such inference cannot be based on possibilities,
    surmise or conjecture. . . . It is axiomatic, therefore,
    that [a]ny [inference] drawn must be rational and
    founded upon the evidence. . . . However, [t]he line
    between permissible inference and impermissible spec-
    ulation is not always easy to discern. When we infer,
    we derive a conclusion from proven facts because such
    consideration as experience, or history, or science have
    demonstrated that there is a likely correlation between
    those facts and the conclusion. If that correlation is
    sufficiently compelling, the inference is reasonable. But
    if the correlation between the facts and the conclusion
    is slight, or if a different conclusion is more closely
    correlated with the facts than the chosen conclusion,
    the inference is less reasonable. At some point, the
    link between the facts and the conclusion becomes so
    tenuous that we call it speculation. When that point is
    reached is, frankly, a matter of judgment.’’ (Internal
    quotation marks omitted.) State v. Billie, 
    123 Conn. App. 690
    , 696, 
    2 A.3d 1034
     (2010).
    The substance of the charge allowed the jury to infer
    that the defendant had possessed child pornography if
    it found that the defendant had exclusive control of the
    computer. On the basis of the evidence presented, the
    jury reasonably could have concluded that the defen-
    dant was the only person with control and access to
    the password protected computer that contained child
    pornography. Therefore, this instruction was both rea-
    sonable and logical. The constantly changing nature
    of technology and crime require that judges have the
    flexibility to adapt model jury instructions to the facts
    of a case. Read as a whole, the trial court’s instruction
    adequately explained to the jury each of the elements
    required before a person may be convicted of posses-
    sion of child pornography in the first degree. It was not
    reasonably possible that the jury was misled by the
    instruction regarding possession. The defendant, there-
    fore, was not deprived of a fair trial on the basis of
    improper jury instructions.

    Finally, the defendant claims that the trial court
    abused its discretion when it allowed the state to pre-
    sent rebuttal evidence concerning the clock settings on
    the defendant’s computer. Although the state had the
    opportunity to present this evidence during its case-in-
    chief, the evidence in question became relevant only
    when the defendant opened the door by presenting an
    alibi defense that he was working when the porno-
    graphic images were downloaded. The trial court did
    not abuse its discretion by allowing the state to present
    its rebuttal evidence.
    The following additional facts are relevant to the
    defendant’s claim. During the presentation of the state’s
    case-in-chief, defense counsel cross-examined Detec-
    tive Aresco about the dates and times that the porno-
    graphic images were downloaded to the defendant’s
    computer. Defense counsel provided Aresco with a
    copy of the state police computer analysis report that
    had been generated following an examination of the
    defendant’s computer. Using the report to refresh his
    memory, Aresco read the dates and times captured in
    the report for when specific files were downloaded.5
    On redirect examination, Aresco testified that based on
    his training, the report’s recorded download time was
    not reliable evidence.6 On recross-examination, Aresco
    testified that the file download times captured in the
    report may have been off by at least two hours from
    the time when the files were actually downloaded by
    the defendant because Aresco observed that the clock
    in the computer was set to the Pacific time zone.7 The
    next day, after the state rested and prior to the defense
    presenting any witnesses, the state informed the court
    that following his testimony, Aresco had further
    reviewed file download times and found that his testi-
    mony regarding a two hour difference in time was incor-
    rect. Aresco was now prepared to testify that when
    he examined the computer he observed a nine hour
    difference between the clock in the defendant’s com-
    puter and the ‘‘actual time.’’8 The state informed the
    court and defense counsel that Aresco would be pre-
    sented as a rebuttal witness. The defendant objected
    to any rebuttal testimony regarding the time to which
    the clock in the computer was set because he consid-
    ered it to be new forensic evidence that was available
    to the state before it rested its case. The trial court
    deferred making a ruling on the objection so it could
    consider the defendant’s argument.
    The defendant then called as his first witness a man-
    ager from the bus company where he was employed.
    The manager testified to the dates and times when the
    defendant drove his bus route. The defendant sought
    to establish that he was driving a bus at the time that
    the child pornography images were downloaded to his
    computer. This theory was predicated on Aresco’s ear-
    lier testimony regarding when each illicit image was
    downloaded to the defendant’s computer.
    After the defendant rested his case, the trial court
    found that the defendant would not be prejudiced by
    rebuttal testimony from Aresco because the defendant
    had been given notice of the state’s claim that the time
    recorded on the computer was inaccurate.9 Aresco
    returned to the witness stand and testified that he had
    been mistaken in his prior testimony and that he had
    observed a nine hour difference between the time on
    the clock in the defendant’s computer and the ‘‘actual
    time.’’10 The defendant cross-examined Aresco about
    why his testimony changed and the difference in time.
    ‘‘The admission of rebuttal evidence ordinarily is
    within the sound discretion of the trial court. In consid-
    ering whether a trial court has abused its discretion,
    appellate courts view such a trial court ruling by making
    every reasonable presumption in favor of the decision
    of the trial court.’’ (Internal quotation marks omitted.)

    ‘‘[R]ebuttal evidence is that which refutes the evi-
    dence presented by the defense. . . . When a defen-
    dant offers evidence in his defense, it is appropriate
    for the state to offer evidence to refute it, if possible.’’

     (1996).
    ‘‘Generally, a party who delves into a particular subject
    during the examination of a witness cannot object if
    the opposing party later questions the witness on the
    same subject. . . . The party who initiates discussion
    on the issue is said to have opened the door to rebuttal
    by the opposing party. . . . The doctrine of opening
    the door cannot, of course, be subverted into a rule for
    injection of prejudice. . . . The trial court must care-
    fully consider whether the circumstances of the case
    warrant further inquiry into the subject matter, and
    should permit it only to the extent necessary to remove
    any unfair prejudice which might otherwise have
    ensued from the original evidence. . . . Thus, in mak-
    ing its determination, the trial court should balance the
    harm to the state in restricting the inquiry with the
    prejudice suffered by the defendant in allowing the
    rebuttal.’’ (Internal quotation marks omitted.) State v.
    Brown, 
    309 Conn. 469
    , 479, 
    72 A.3d 48
     (2013).
    On the basis of our review, we conclude that the trial
    court did not abuse its discretion by permitting the
    state to recall the pertinent witness to clarify an earlier
    representation as to when child pornography was down-
    loaded to the defendant’s computer. The testimony was
    proper rebuttal evidence. The defendant was on notice
    of the timing issue and was able to cross-examine the
    witness on rebuttal. See State v. Cavell, supra, 
    235 Conn. 728
     (state forensic analysis that was not relevant during
    case-in-chief was allowed as rebuttal evidence). The
    state was not required to prove the timing of when
    the child pornography was downloaded, only that the
    defendant was in possession of it. It was the defense
    that made relevant the computer recorded download
    times.
    It is true that the state could have determined the
    exact discrepancy between the clock in the computer
    and the actual time prior to the presentation of its case-
    in-chief, but the topic became relevant only when the
    defendant raised the issue during cross-examination of
    Aresco. In this case, the defendant opened the door to
    the issue of download times in order to lay the founda-
    tion for the later testimony of the defendant’s employer,
    who would assert that the defendant was working at
    the time when the images allegedly were downloaded.
    The defendant never filed a notice of an alibi defense
    that would have informed the state of this theory. There-
    fore, prior to the cross-examination of Aresco, it was
    reasonable for the state to believe that the timing of
    the image downloads was not relevant to the trial and
    not a topic that required the presentation of evidence.
    Following the defendant’s cross-examination of Are-
    sco, the state took immediate steps to determine the
    actual temporal discrepancy and informed the trial
    court and the defendant that it would seek to introduce
    rebuttal evidence. Prior to presenting his defense, the
    defendant was aware that the state was prepared to
    offer rebuttal evidence regarding the computer time.
    The defendant did not seek a continuance to afford
    himself time to address the state’s additional evidence.
    The trial court was within its discretion to allow the
    state to refute the testimony presented by the
    defendant.
    The judgment is affirmed.
    In this opinion the other judges concurred.

    General Statutes § 53a-196d (a) provides in relevant part: ‘‘A person is
    guilty of possessing child pornography in the first degree when such person
    knowingly possesses (1) fifty or more visual depictions of child pornogra-
    phy . . . .’’

    During the trial, state police Detective David Aresco described peer-to-
    peer file sharing: ‘‘A peer-to-peer file share network is a network that facili-
    tates the transfer of digital files from one user to another user. When I say
    one user, I mean one computer user signed onto the network . . . .’’

    In Mangual, the police made a ‘‘show of force that included drawn
    handguns [and] one or more rifles . . . .’’ Id., 200.

    ‘‘[I]n summary, the state must prove beyond a reasonable doubt that
    the defendant possessed child—that one, the defendant possessed child
    pornography, two, he was aware of the nature and contents of the material,
    and three, it consisted of fifty or more visual depictions. If you unanimously
    find the state has proved beyond a reasonable doubt each of the elements
    of the crime of possessing child pornography in the first degree, then you
    shall find the defendant guilty.’’
    5
    The words ‘‘created’’ and ‘‘downloaded’’ were used interchangeably dur-
    ing the trial. Both were references to the date and time recorded by the
    computer when an image was added to the defendant’s computer hard drive.
    6
    ‘‘[The Prosecutor]: [Detective Aresco] [y]ou referenced before the file
    created time, and you gave an explanation as to what that means. But in
    your experience and training in this particular area, does that have any
    significant value in your investigation?
    ‘‘[The Witness]: No, sir. . . .
    ‘‘[The Prosecutor]: And why is that, sir?
    ‘‘[The Witness]: Those times are not reliable.
    ‘‘[The Prosecutor]: And why is that?
    ‘‘[The Witness]: Because it’s capturing that time from the time that is set
    on the computer . . . . That time is coming off of whatever time [the defen-
    dant’s computer] was presently set at when that file was created or any file
    is created. And I have no way of verifying what time a particular computer
    was set at. No forensic examiner would come up here and testify to the
    reliability of times because they can be manipulated.’’
    7
    ‘‘The time was off. It was set to Pacific time and I did the calculation,
    I believe it was two hours off to the actual time.’’ Aresco stated that he
    could testify about the setting of the clock in the computer only as of the
    date when he examined the computer, not any previous date when the files
    were actually downloaded. His review of the clock in the computer occurred
    two weeks prior to the defendant’s trial in September, 2013.
    8
    ‘‘[A]ctual time’’ is the phrase that Aresco used throughout his testimony
    to differentiate between the time he observed on the clock in the computer
    and the time on the day when he was examining the computer.
    9
    The court stated: ‘‘[T]he defense certainly knew the state’s claim would
    be that the time was off. Maybe not specifically the exact time differential,
    but that did come out through the redirect of the forensic examiner. So,
    they were on notice of that. And then prior to calling specifically the defense
    witness, the state, although it didn’t have to, certainly put the defense on
    notice that they had gone back and checked the exact time differential, and
    it was greater than either Pacific time or two hours, which was the testimony
    based on recollection, and was actually nine hours.
    ‘‘So, given that, I don’t believe the defendant was prejudiced. This is an
    issue that obviously the defense raised. I understand why the defense raised
    it. But the state should be able to respond to it. And I don’t believe there
    was—there’s prejudice by calling the witness to rebut that testimony.’’
    10
    ‘‘[The Witness]: I checked the time of the computer, the imaged computer
    just to make sure that my testimony as far as, you know, me believing that
    it was two hours off was accurate.
    ‘‘[The Prosecutor]: Okay. And what did you do with respect to that issue?
    ‘‘[The Witness]: I actually turned on the laptop computer that I used to
    make the demos. And that laptop computer contained the imaged hard drive,
    the hard drive that we seized the day of the search warrant. So, I turned
    on the computer and I checked the time.
    ‘‘[The Prosecutor]: And what did you find with respect to checking the
    time?
    ‘‘[The Witness]: I found that the time was actually nine hours and twenty-
    two minutes off, meaning the time of the computer was nine hours and
    twenty-two minutes ahead of the actual time.’’
