    MARCOS MERCADO v. COMMISSIONER OF
    CORRECTION
    (AC 39802)
    Alvord, Keller and Prescott, Js.
    Syllabus
    The petitioner, who had been convicted of murder, felony murder, and
    robbery in the first degree, sought a writ of habeas corpus, claiming
    that his trial counsel had provided ineffective assistance by, inter alia,
    failing to object to the use of testimony elicited from the petitioner on
    cross-examination and from his former girlfriend, B, in the state’s rebut-
    tal, regarding whether the petitioner had acknowledged to B that he
    had committed certain crimes in the past. The petitioner also claimed
    that his trial counsel was ineffective in failing to object to evidence
    pertaining to the petitioner’s possession of a certain assault rifle seized
    incident to his arrest, and failing to present testimony from a firearms
    expert to prove that the assault rifle was not the murder weapon. The
    habeas court rendered judgment denying the habeas petition on the
    ground that the petitioner had failed to establish that trial counsel’s
    claimed errors prejudiced him and, thereafter, denied the petition for
    certification to appeal, and the petitioner appealed to this court. Held
    that the habeas court did not abuse its discretion in denying the petition
    for certification to appeal, as the petitioner failed to show that there
    was a reasonable probability that but for trial counsel’s alleged unprofes-
    sional errors, the result of the proceeding would have been different:
    it was unlikely that the preclusion of the challenged evidence would
    have changed the result of the petitioner’s criminal trial when viewed
    in the context of the overwhelming amount of evidence against the
    petitioner, including his voluntary confession to the police that he shot
    the victim with the assault rifle that he retrieved from the trunk of
    his vehicle and that he took the victim’s game console, which was
    corroborated by forensic evidence and the testimony of, inter alia, the
    state’s experts and B, and the petitioner could not show that if his trial
    counsel had presented the evidence of his own firearms expert, the
    result of his criminal trial would have been different, as the petitioner
    failed to show that such an expert would have offered any opinions in
    addition or contrary to those of the state’s expert at his criminal trial;
    furthermore, the petitioner could not prevail on his claim that his trial
    counsel had provided ineffective assistance by failing to object to the
    state’s recalling of B on rebuttal and to adequately preserve that issue
    for purposes of appellate review, as the testimony of the petitioner’s
    criminal defense expert at the habeas trial established only that this
    court did not review the petitioner’s claim on direct appeal because it
    was not preserved for appeal, and in the absence of expert testimony
    that this court would have reversed the petitioner’s conviction had trial
    counsel preserved the record for appeal, the petitioner had provided
    no basis from which a court could find a reasonable probability that
    the result of his appeal would have been different.

    Opinion
    ALVORD, J. The petitioner, Marcos Mercado, appeals
    from the denial of his petition for certification to appeal
    from the judgment of the habeas court denying his
    petition for a writ of habeas corpus. On appeal, the
    petitioner claims that the habeas court abused its dis-
    cretion in denying his petition for certification to appeal
    and improperly rejected his claim that his trial counsel
    rendered ineffective assistance. Specifically, the peti-
    tioner claims that his trial counsel rendered ineffective
    assistance by failing: (1) to take appropriate measures
    at trial to preclude the introduction of evidence of the
    petitioner’s prior commission of crimes; (2) to take
    appropriate measures to preclude, or failing to call an
    expert to challenge, the state’s introduction of firearms
    and ballistics evidence; and (3) to adequately preserve
    an issue for appellate review. We conclude that the
    habeas court did not abuse its discretion in denying
    the petition for certification to appeal. Accordingly, we
    dismiss the appeal.
    The following facts, as set forth by this court on the
    petitioner’s direct appeal, are relevant to our resolution
    of the petitioner’s claims. ‘‘On December 26, 2007, the
    Southington police went to the apartment of the victim,
    Thomas Szadkowski, at 81 Academy Street to check on
    his welfare, as he had not reported to work that day.
    The police found the victim in his kitchen, lying dead
    of a gunshot wound. During their search of the victim’s
    apartment, the Southington and state police observed
    a number of open windows on the screen of the victim’s
    computer. One window depicted an America Online
    instant message exchange between the [petitioner] and
    the victim, which took place between approximately
    8:45 and 9:45 p.m. on December 24, 2007.
    ‘‘The instant message screen revealed that the victim
    had invited the [petitioner] to his apartment. Another
    open screen displayed the [petitioner’s] photograph and
    profile. The [petitioner] accepted the invitation and
    drove to the victim’s apartment. After the [petitioner]
    and the victim engaged in a sexual act, the [petitioner]
    retrieved a gun from his motor vehicle, returned to
    the victim’s apartment and shot him. When he left the
    apartment, the [petitioner] took the victim’s Xbox 360
    game console (Xbox). On December 26, 2007, the [peti-
    tioner] gave the Xbox to a former girlfriend, Laurel
    Brooks, as a gift for her younger brother. The [peti-
    tioner] was arrested at his home in New Britain on
    December 30, 2007. He subsequently signed a written
    statement and confessed, during a videotaped inter-
    view, to having shot the victim.1’’ (Footnote in original.)

     (2012).
    The court appointed Attorneys Christopher D. Eddy
    and Kenneth W. Simon to represent the petitioner. In
    a substitute long form information, the state charged the
    petitioner with murder in violation of General Statutes
    § 53a-54a, felony murder in violation of General Statutes
    § 53a-54c, and robbery in the first degree in violation
    of General Statutes § 53a-134 (a) (2). After a trial, the
    jury found the petitioner guilty of all three counts. The
    trial court, Espinosa, J., merged the felony murder con-
    viction into the murder conviction and sentenced the
    petitioner to a total effective sentence of seventy years
    incarceration on the murder and robbery charges. The
    petitioner appealed from the judgment of conviction,
    which this court affirmed. See id., 100, 107. The peti-
    tioner then petitioned for certification to our Supreme
    Court, which that court denied. State v. Mercado, 
    307 Conn. 943
    , 
    56 A.3d 951
     (2012).
    On March 3, 2016, the petitioner filed a third amended
    petition for a writ of habeas corpus, in which he alleged
    the ineffective assistance of his trial counsel. Specifi-
    cally, as summarized by the habeas court in its memo-
    randum of decision, the petitioner claimed that his trial
    counsel provided him with ineffective assistance by
    ‘‘failing to object, exclude, or move to limit the use of
    testimony elicited from the petitioner on cross-exami-
    nation and from Laurel Brooks, in the state’s rebuttal,
    regarding whether the petitioner had acknowledged to
    Brooks having committed robberies in the past . . .
    failing to object, exclude, or move to limit the use of
    evidence pertaining to the petitioner’s possession of
    a .223 caliber [AR-15] Bushmaster assault rifle seized
    incident to his arrest . . . failing to present testimony
    from a firearms expert to prove that [the] Bushmaster
    rifle was not the murder weapon; and . . . failing to
    investigate adequately the possibility that Richard Diaz
    was the real culprit.’’2
    A trial commenced before the habeas court, Sfer-
    razza, J., on October 3, 2016. The court heard testimony
    from Lieutenant Joseph Rainone, a Waterbury police
    officer who testified at the petitioner’s criminal trial as
    a firearms expert for the state; Dr. Albert Harper, a
    firearms expert; Attorneys Eddy and Simon; Diaz; Car-
    men Baez, an investigator for the Office of the Public
    Defender; Attorney Sebastian DeSantis, a Connecticut
    criminal defense attorney; and the petitioner.
    After trial, in a written memorandum of decision
    dated October 13, 2016, the habeas court denied the
    petition for a writ of habeas corpus. The court deter-
    mined that the petitioner had failed to establish that trial
    counsel’s claimed errors prejudiced him. The petitioner
    then filed a petition for certification to appeal, which
    the habeas court denied. This appeal followed.
    ‘‘Faced with a habeas court’s denial of a petition for
    certification to appeal, a petitioner can obtain appellate
    review of the dismissal of his petition for habeas corpus
    only by satisfying the two-pronged test enunciated by
    our Supreme Court in Simms v. Warden, 
    229 Conn. 178
    , 
    640 A.2d 601
     (1994), and adopted in Simms v.
    Warden, 
    230 Conn. 608
    , 612, 
    646 A.2d 126
     (1994). First,
    [the petitioner] must demonstrate that the denial of
    his petition for certification constituted an abuse of
    discretion. . . . Second, if the petitioner can show an
    abuse of discretion, he must then prove that the deci-
    sion of the habeas court should be reversed on the
    merits. . . . A petitioner may establish an abuse of dis-
    cretion by demonstrating that the issues are debatable
    among jurists of reason . . . [the] court could resolve
    the issues [in a different manner] . . . or . . . the
    questions are adequate to deserve encouragement to
    proceed further. . . . In determining whether the
    habeas court abused its discretion in denying the peti-
    tioner’s request for certification, we necessarily must
    consider the merits of the petitioner’s underlying claims
    to determine whether the habeas court reasonably
    determined that the petitioner’s appeal was frivolous.’’

    ing the petition for certification to appeal. Our standard
    of review of a habeas court’s judgment on ineffective
    assistance of counsel claims is well settled. In a habeas
    appeal, this court cannot disturb the underlying facts
    found by the habeas court unless they are clearly erro-
    neous, but our review of whether the facts as found by
    the habeas court constituted a violation of the petition-
    er’s constitutional right to effective assistance of coun-
    sel is plenary.’’ (Internal quotation marks omitted.)

    lishing that (1) counsel’s representation fell below an
    objective standard of reasonableness, and (2) counsel’s
    deficient performance prejudiced the defense because
    there was a reasonable probability that the outcome of

    .
    The petitioner contends on appeal that the habeas
    court abused its discretion in denying his petition for
    certification to appeal because his trial counsel ren-
    dered ineffective assistance in three respects. He first
    claims that trial counsel was ineffective in ‘‘failing to
    take appropriate measures to preclude the admission
    of the highly prejudicial evidence of Mr. Mercado’s prior
    commission of crimes.’’ Specifically, he argues that trial
    counsel ‘‘did not adequately object’’ when the state elic-
    ited testimony from the petitioner at his criminal trial
    regarding statements he allegedly made to Brooks about
    committing crimes in the past,3 and ‘‘did not adequately
    object’’ when the state recalled Brooks on rebuttal.4
    The petitioner’s second claim is that trial counsel
    was ineffective in failing to take appropriate measures
    to preclude, or failing to call an expert to challenge, the
    state’s introduction of firearms and ballistics evidence.
    Specifically, he argues that trial counsel did not ‘‘take
    appropriate measures to preclude the introduction of
    highly prejudicial irrelevant evidence, including the .223
    caliber AR-15 Bushmaster assault [rifle] seized from
    [the petitioner’s] home, two .22 caliber bullets, and ref-
    erences to a conversion kit which would not have ren-
    dered the AR-15 Bushmaster capable of firing .22 caliber
    bullets.’’ He further argues that trial counsel was inef-
    fective in failing to introduce expert testimony to estab-
    lish that ‘‘the conversion kit the state alleged Mr.
    Mercado possessed did not render the .223 caliber AR-
    15 Bushmaster weapon capable of firing the fatal bul-
    let.’’ The petitioner contends that these errors ‘‘provided
    a basis for the jury to convict the [petitioner] on side
    issues.’’
    Finally, and closely related to his first claim, the peti-
    tioner claims that by failing to object to the state’s
    recalling of Brooks on rebuttal, trial counsel ‘‘failed to
    adequately preserve [the] issue for purposes of appel-
    late review.’’ He notes that, on direct appeal of his
    conviction to this court, this court declined to review
    his claims related to the admission of Brooks’ testimony
    because ‘‘the issue had not been properly preserved
    by trial [counsel] during the criminal proceeding.’’ See
    footnote 4 of this opinion. He contends that ‘‘his convic-
    tion would have been overturned had trial [counsel]
    preserved the issue properly.’’ We address the petition-
    er’s claims together.
    ‘‘Because the court determined that the petitioner
    had not proven that he was prejudiced by the perfor-
    mance of his trial counsel, our focus on review is
    whether the court correctly determined the absence of
    prejudice.’’ Weinberg v. Commissioner of Correction,
    
    112 Conn. App. 100
    , 108, 
    962 A.2d 155
    , cert. denied, 
    291 Conn. 904
    , 
    967 A.2d 1221
     (2009). ‘‘With respect to the
    prejudice component of the Strickland test, the peti-
    tioner must demonstrate that counsel’s errors were so
    serious as to deprive the [petitioner] of a fair trial, a
    trial whose result is reliable. . . . It is not enough for
    the [petitioner] to show that the errors had some con-
    ceivable effect on the outcome of the proceedings. . . .
    Rather, [t]he [petitioner] must show that there is a rea-
    sonable probability that, but for counsel’s unprofes-
    sional errors, the result of the proceeding would have
    been different. A reasonable probability is a probability
    sufficient to undermine confidence in the outcome.
    . . . When a [petitioner] challenges a conviction, the
    question is whether there is a reasonable probability
    that, absent the errors, the fact finder would have had a
    reasonable doubt respecting guilt.’’ (Internal quotation
    marks omitted.) 
    Id., 107
    .
    We conclude that the habeas court did not abuse its
    discretion in denying the petition for certification to
    appeal. The petitioner failed to satisfy his burden of
    showing a reasonable probability that had trial counsel
    objected to the complained of evidence, or presented
    the testimony of a firearms expert, the fact finder would
    have had a reasonable doubt respecting guilt. Notably,
    the petitioner presented no support for his contention
    that ‘‘the jury did not consider the evidence overwhelm-
    ing’’ beyond the fact that the jury deliberated for four
    days before reaching a verdict.5 Upon review, nothing
    in the record suggests that but for the claimed errors
    of trial counsel, the result of the trial would have
    been different.6
    We note that ‘‘[t]he strength of the state’s case is a
    significant factor in determining whether an alleged
    error caused prejudice to the petitioner. The stronger
    the case, the less probable it is that a particular error
    caused actual prejudice.’’ (Internal quotation marks
    omitted.) Weinberg v. Commissioner of Correction,
    supra, 
    112 Conn. App. 115
    . As the habeas court rightfully
    concluded, the state’s case against the petitioner
    included an ‘‘overwhelming’’ amount of forensic evi-
    dence and testimony to support a finding of guilt. That
    evidence included: (1) physical evidence at the crime
    scene that ‘‘largely corresponded’’ with details supplied
    by the petitioner in his voluntary confession;7 (2)
    Brooks’ testimony that the petitioner brought her an
    Xbox, without its box, on December 26, 2007, which
    she later gave to Detective Jay Suski of the Southington
    Police Department; (3) testimony of Officer Michael
    David Kahn, a systems administrator for the town of
    Southington, that Xbox serial numbers are unique to
    each unit; (4) Detective Suski’s testimony that the serial
    number on the Xbox seized from Brooks’ home matched
    the serial number listed on a receipt seized from the
    victim’s home; (5) Brooks’ testimony that when the
    petitioner visited her on December 26, he was exhibiting
    strange behavior, including physically shaking; (6)
    Brooks’ testimony that during that visit, the petitioner
    told her he had ‘‘done something,’’ and that ‘‘there was
    a witness, but there’s not anymore,’’ and then asked
    ‘‘how come it doesn’t bother him’’; (7) Lieutenant Rai-
    none’s testimony that upon comparing a .22 caliber
    bullet recovered in the petitioner’s backyard, where
    the petitioner engaged in target shooting, with the .22
    caliber bullet removed from the victim’s head, he deter-
    mined that the two bullets were fired from the same
    gun; (8) Lieutenant Rainone’s testimony that, although
    the .223 caliber AR-15 seized from the petitioner’s home
    was incapable of firing a .22 caliber bullet, it could be
    modified to fire a .22 caliber bullet; (9) evidence that
    demonstrated that the petitioner had access to both .22
    caliber firearms, as well as adapters capable of allowing
    the seized AR-15 to fire a .22 caliber bullet; (10) images
    of messages exchanged between screen names associ-
    ated with the petitioner and the victim,8 showing that
    the petitioner had communicated with the victim on
    the evening of December 24, 2007, and arranged to
    meet at the victim’s home; (11) forensic analysis of the
    petitioner’s and the victim’s computers confirming that
    communication occurred between the petitioner and
    the victim on December 24, 2007; (12) testimony of
    Diaz, whom the petitioner attempted to portray as the
    perpetrator of the crimes here, regarding his verifiable
    alibi on Christmas Eve, 2007;9 and (13) Diaz’ testimony
    that when he visited the petitioner while the petitioner
    was incarcerated prior to his trial, the petitioner con-
    fessed to him that ‘‘he did it.’’
    Perhaps most significantly, the petitioner also volun-
    tarily confessed to killing the victim and then taking
    his Xbox.10 In a voluntary statement given to Lieutenant
    James P. Wardwell of the New Britain Police Depart-
    ment, the petitioner confessed to communicating with
    the victim on the evening of December 24, 2007, via
    America Online instant messenger, arranging to meet
    the victim at the victim’s home so that the petitioner
    could perform a sexual act on the victim, visiting the
    victim’s home soon after arranging the meeting, per-
    forming the agreed upon sexual act on the victim, and
    then shooting the victim with an AR-15 that he retrieved
    from the trunk of his vehicle. As the habeas court noted,
    that confession was video recorded. At the petitioner’s
    criminal trial, both an audio-visual recording and a tran-
    script of the confession were admitted as full exhibits.
    When considered in light of the petitioner’s detailed,
    and largely corroborated confession, it is difficult to
    imagine how trial counsel’s claimed errors caused him
    to suffer prejudice. See Lewis v. Commissioner of Cor-
    rection, 
    89 Conn. App. 850
    , 866, 
    877 A.2d 11
     (agreeing
    with habeas court’s conclusion that even if trial counsel
    should have objected to witness’ testimony regarding
    petitioner’s post-Miranda silence, petitioner was not
    prejudiced as result of counsel’s failure to do so because
    state had already elicited testimony that petitioner
    twice confessed to killing victim), cert. denied, 
    275 Conn. 905
    , 
    882 A.2d 672
     (2005).
    We agree with the habeas court that the inculpatory
    evidence against the petitioner was ‘‘overwhelming and
    rooted in the petitioner’s voluntary confession, which
    the jury had . . . occasion to review visually and audi-
    bly. The specifics of that confession were corroborated
    in every salient respect by forensic evidence and testi-
    mony. The purported deficiencies of defense counsel
    were truly insignificant when weighed against the evi-
    dence that supported the jury’s verdict.’’ Viewed in the
    context of this overwhelming amount of evidence
    against him, it is unlikely that preclusion of the chal-
    lenged evidence would have changed the result of the
    petitioner’s criminal trial. See, e.g., Arthur v. Commis-
    sioner of Correction, 
    162 Conn. App. 606
    , 624, 
    131 A.3d 1267
     (‘‘we conclude on the basis of our review of the
    evidence that the petitioner cannot demonstrate preju-
    dice because the [challenged] evidence was not signifi-
    cant to the state’s case’’), cert. denied, 
    323 Conn. 915
    ,
    
    149 A.3d 496
     (2016); cf. Eubanks v. Commissioner of
    Correction, 
    166 Conn. App. 1
    , 21, 
    140 A.3d 402
     (‘‘the
    failure of the petitioner’s trial counsel to object to the
    admission of [the witness’] . . . testimony on hearsay
    grounds prejudiced the petitioner because when the
    corroborating evidence is viewed in the absence of the
    substantive use of that testimony, there is very little
    evidence to support the petitioner’s conviction’’), cert.
    granted, 
    323 Conn. 911
    , 
    149 A.3d 980
     (2016).
    It is also unlikely that had trial counsel presented the
    testimony of a firearms expert, the jury would have had
    a reasonable doubt concerning guilt.11 As the habeas
    court concluded: ‘‘The prosecution’s own expert testi-
    fied before the jury that the Bushmaster, in the condi-
    tion in which it was found, could not have fired the
    deadly shot. Both the fatal bullet and the bullet recov-
    ered from the petitioner’s backyard were fired out of
    the same barrel, but that barrel was not the one present
    on the Bushmaster found at the petitioner’s residence.’’
    (Emphasis in original.) On the basis of this, the court
    found that ‘‘[t]he jury was completely educated by the
    state’s expert to the precise facts about which a defense
    expert might testify.’’
    We agree with the habeas court’s determination that,
    because the petitioner failed to show that an expert
    would have offered any opinions in addition or contrary
    to those of the state’s expert at his criminal trial, he
    could not show that if trial counsel had presented the
    evidence of his own expert, the result of his criminal
    trial would have been different. The petitioner, there-
    fore, failed to show that he was prejudiced by trial
    counsel’s failure to present cumulative expert testi-
    mony. See, e.g., Hall v. Commissioner of Correction,
    supra, 
    152 Conn. App. 610
     (‘‘[b]ecause the videotape
    was merely cumulative of the testimony of numerous
    eyewitnesses who identified the petitioner as the [per-
    petrator], the petitioner cannot show that as a result
    of his trial counsel’s deficient performance, there
    remains a probability sufficient to undermine confi-
    dence in the verdict that resulted in his appeal’’ [internal
    quotation marks omitted]); Weinberg v. Commissioner
    of Correction, supra, 
    112 Conn. App. 108
     (affirming
    habeas court’s conclusion that petitioner had failed to
    demonstrate that he was prejudiced by trial counsel’s
    failure ‘‘to disprove adequately that the knife seized
    from the petitioner’s apartment could have caused the
    victim’s wounds,’’ on the basis that petitioner’s evidence
    at habeas trial regarding knife ‘‘was not substantively
    different from the evidence trial counsel elicited from
    the medical examiner during the underlying criminal
    trial’’); Madagoski v. Commissioner of Correction, 
    104 Conn. App. 768
    , 775-76, 
    936 A.2d 247
     (2007) (concluding
    that petitioner failed to demonstrate that fact finder
    would have reasonable doubt as to petitioner’s guilt
    if trial counsel had interviewed and called potential
    witness, because ‘‘his testimony, at most, would have
    been cumulative of other evidence’’), cert. denied, 
    286 Conn. 905
    , 
    944 A.2d 979
     (2008).
    Finally, with respect to the petitioner’s claim that
    trial counsel failed to preserve an issue for appeal, the
    petitioner has failed to satisfy his burden of showing a
    reasonable probability that, had trial counsel objected
    to Brooks’ testimony, his conviction would have been
    overturned on appeal. The habeas court rejected the
    petitioner’s argument that but for trial counsel’s alleged
    errors, the outcome of his appeal would have been
    different. The petitioner, in his brief to this court, argues
    that he has shown prejudice by pointing to the trial
    court’s ‘‘threshold determination in granting the [peti-
    tioner’s] motion in limine that the evidence was indeed
    prejudicial,’’ and ‘‘the expert legal testimony introduced
    at the habeas trial.’’ Upon review of the record, how-
    ever, it is clear that Attorney DeSantis’ testimony to
    which the petitioner refers establishes only that this
    court did not review the petitioner’s claim on direct
    appeal because it was not preserved for appeal, which
    is not in dispute.
    A further review of Attorney DeSantis’ testimony
    reveals that he testified only that a reasonably compe-
    tent attorney would have objected to the state’s attempt
    to ask the petitioner about his ‘‘other crimes’’ conversa-
    tion with Brooks, which, if sustained, would have had
    the effect of precluding ‘‘other crimes testimony’’ from
    Brooks. He further testified that if the objection were
    overruled, it would have preserved the record for
    appeal. At no time did Attorney DeSantis testify that
    had trial counsel preserved the record for appeal, this
    court would have reversed the petitioner’s conviction.
    Therefore, in light of the fact that the petitioner has
    provided no basis from which a court could find a
    reasonable probability that the result of his appeal
    would have been different, we agree with the habeas
    court’s finding that the petitioner failed to prove that
    he was prejudiced by this claimed error.
    Simply put, even if we were to determine that trial
    counsel’s performance was deficient, in light of our
    review of the record and the sheer strength of the state’s
    case against the petitioner, we conclude that the peti-
    tioner’s claim that the result of his criminal proceedings
    would have been different is highly speculative at best.12
    The petitioner has failed to demonstrate that the issues
    raised are debatable among jurists of reason, that a
    court could resolve the issues in a different manner, or
    that the questions deserve encouragement to proceed
    further. Accordingly, the habeas court did not abuse
    its discretion in denying the petition for certification
    to appeal.
    The appeal is dismissed.
    In this opinion the other judges concurred.

    ‘‘The [petitioner] filed a motion to suppress his statements claiming that
    they were the product of police intimidation and coercion and therefore
    were not voluntary. The court denied the motion to suppress. Before the
    jury, the [petitioner] testified that his written and videotaped statements
    were not the truthful product of his free will. He agreed to sign the statements
    to provide the police with the information they wanted in order to end the
    police questioning.’’ State v. Mercado, 
    139 Conn. App. 99
    , 101 n.3, 
    54 A.3d 633
    , cert. denied,

    On January 1, 2008, Brooks gave a voluntary statement to Detective Jay
    Suski of the Southington Police Department, in which she stated: ‘‘Marcos
    has talked to me in the past about committing crimes. He’s talked about
    wanting to do robberies. He would give me details about how he would tie
    people up or break into their home when they weren’t home.’’
    4
    Before the state called Brooks to testify during its case-in-chief, trial
    counsel filed a motion in limine to preclude her from ‘‘testifying concerning
    the [petitioner’s] alleged past about committing crimes.’’ (Internal quotation
    marks omitted.) State v. Mercado, supra, 
    139 Conn. App. 102
    . Trial counsel
    argued that the probative value of such testimony would be outweighed by
    its prejudicial effect. 
    Id.
     The trial court granted the motion in limine with
    respect to the state’s direct examination of Brooks, finding that ‘‘the preju-
    dice outweighs the probative value with respect to the statement that [the
    petitioner] has talked to me [Brooks] in the past about committing crimes.’’
    (Internal quotation marks omitted.) 
    Id.,
     102–103. The court, however, explic-
    itly noted that ‘‘the motion is granted with respect to the testimony on direct
    examination. If the defense on cross-examination opens the door or upon
    cross-examination of the [petitioner], then this would not—the court’s
    order doesn’t apply.’’ (Emphasis added; internal quotation marks omitted.)
    
    Id., 103
    .
    The state offered Brooks’ testimony in conformity with the court’s order.
    
    Id.
     On cross-examination of the petitioner, the state requested permission
    from the court to question the petitioner about whether he had made these
    statements to Brooks. 
    Id.,
     103–104. Trial counsel objected, arguing that the
    probative value of the petitioner’s statements were outweighed by their
    prejudicial effect. 
    Id., 104
    . The court overruled the objection, and the state
    questioned the petitioner about these statements. 
    Id.
     The petitioner denied
    making the statements. 
    Id.
     During its rebuttal case, the state recalled Brooks,
    and elicited testimony regarding these statements. 
    Id.
     Trial counsel did not
    object to recalling Brooks or her resulting testimony. 
    Id.,
     104–105.
    On direct appeal to this court, the petitioner claimed that (1) the trial
    court abused its discretion by permitting the prosecutor to cross-examine
    him about prior misconduct that did not fall within the exception governing
    admissibility of prior misconduct evidence contained in § 4-5 (b) of the 2009
    edition of the Connecticut Code of Evidence, now § 4-5 (c), and (2) the
    prosecutor’s ‘‘deliberate violation’’ of the court’s ruling on the motion in
    limine while examining Brooks on rebuttal warranted reversal of his convic-
    tion. See id., 100, 105. With respect to the first claim, this court concluded
    that because trial counsel objected to the state eliciting this testimony only
    on the basis that the evidence was more prejudicial than probative, not that
    it constituted inadmissible prior misconduct, the claim was not preserved
    for appeal. Id., 104, 106–107. With respect to the second claim, this court
    concluded that because trial counsel did not object to the state’s examination
    of Brooks on rebuttal, seek to have her rebuttal testimony stricken, or request
    a limiting or curative instruction, that claim was likewise unpreserved for
    appeal. Id., 105–106. This court declined to review those unpreserved eviden-
    tiary claims and affirmed the judgment of the trial court. Id., 107.
    5
    The petitioner argues that ‘‘the record reveals the jury considered Brooks’
    testimony central to its determination of guilt since the jury sought portions
    of her testimony played back.’’ The record reveals that the jury did in fact
    request that one segment of Brooks’ testimony be played back during its
    deliberations but, as stated by the trial court, requested only: ‘‘Can we hear
    Laurel Brooks’ initial testimony March 3rd. That’s number one. Number
    two: Can we see the letter that Marcos wrote to Laurel?’’ (Emphasis added.)
    The first request related to Brooks’ testimony during the state’s case-in-
    chief, and the second referred to a letter that was marked for identification
    during the trial. The court accommodated the first request, but denied
    the second. Notably, Brooks did not testify during the state’s case-in-chief
    regarding the petitioner’s prior commission of crimes; she did so only when
    the state recalled her on rebuttal. The record does not reflect that the
    jury, at any time, requested playback of Brooks’ testimony on rebuttal. We
    therefore reject this argument as unsupported by the record.
    6
    In his brief to this court, the petitioner repeatedly refers to the trial
    court’s ‘‘threshold determination’’ that the evidence regarding his alleged
    statements to Brooks was prejudicial. He argues that ‘‘[t]he criminal trial
    court as a threshold matter determined the prejudice to the [petitioner] of
    this evidence outweighed its probative value in granting [trial counsel’s]
    motion in limine to preclude this evidence. Therefore, this evidence has
    already been deemed prejudicial by the judge who actually presided over
    the criminal trial.’’ According to the petitioner, ‘‘the prejudicial nature of
    the evidence has been established.’’
    The petitioner appears to conflate a determination by the trial court that
    a piece of evidence is prejudicial with a determination of prejudice, in the
    context of an ineffective assistance claim, pursuant to Strickland. As the
    petitioner correctly notes, ‘‘[e]vidence is prejudicial when it tends to have
    some adverse effect upon a defendant beyond tending to prove the fact or
    issue that justified its admission into evidence.’’ (Internal quotation marks
    omitted.) State v. Reynolds, 
    152 Conn. App. 318
    , 326, 
    97 A.3d 999
    , cert.
    denied, 
    314 Conn. 934
    , 
    102 A.3d 85
     (2014). In the context of an ineffective
    assistance claim, however, for a petitioner to satisfy his burden of proving
    that he was prejudiced by counsel’s deficient performance, ‘‘[i]t is not enough
    for the [petitioner] to show that the errors had some conceivable effect on
    the outcome of the proceedings. . . . Rather, [t]he [petitioner] must show
    that there is a reasonable probability that, but for counsel’s unprofessional
    errors, the result of the proceeding would have been different.’’ (Internal
    quotation marks omitted.) Weinberg v. Commissioner of Correction, supra,
    
    112 Conn. App. 107
    . These inquiries are distinct. We therefore reject the
    petitioner’s argument that prejudice was established at the trial court
    because the court granted his motion in limine.
    7
    For example, in the petitioner’s voluntary statement to Lieutenant James
    P. Wardwell, the petitioner confessed to shooting the victim a single time
    ‘‘around his face,’’ dragging the victim’s body from the living room to the
    kitchen, covering the victim’s face with a cloth, and pouring ‘‘soap or some-
    thing’’ all around the victim’s body. Those details were corroborated by
    evidence that the victim died of a single shot to the head, which went from
    front to back, a ‘‘contact transfer blood pattern blood-like stain’’ between
    the living room and kitchen, what appeared to be a pillow burned over the
    face of the victim, and ‘‘an Arm and Hammer-type of liquid, blue liquid that
    was poured on the [victim],’’ as well as the laundry detergent bottle recovered
    near the victim’s body.
    8
    In the petitioner’s voluntary statement to Lieutenant James P. Wardwell,
    he admitted to using the screen name ‘‘Marcos Mercado, Jr.’’
    9
    Specifically, at the criminal trial, Diaz testified that on December 24,
    2007, he went to church with his wife and his daughter around 6 p.m.
    Because it was Christmas Eve, the church was full of other parishioners.
    Following the church service, he, his wife, and his daughter celebrated
    Christmas Eve with his mother-in-law and father-in-law at their house. He,
    his wife, and his daughter returned to their apartment in Southington around
    1 a.m. on Christmas morning.
    His testimony at the habeas trial was largely consistent with his prior
    testimony at the criminal trial. The habeas court found Diaz’ testimony to
    be ‘‘very credible, including his statement that his cousin, the petitioner,
    admitted to him that he killed the victim.’’ ‘‘[T]his court does not retry the
    case or evaluate the credibility of the witnesses. . . . Rather, we must defer
    to the [trier of fact’s] assessment of the credibility of the witnesses based
    on its firsthand observation of their conduct, demeanor and attitude. . . .
    The habeas judge, as the trier of facts, is the sole arbiter of the credibility of
    witnesses and the weight to be given to their testimony.’’ (Internal quotation
    marks omitted.) Mourning v. Commissioner of Correction, 
    169 Conn. App. 444
    , 455, 
    150 A.3d 1166

    10
    As we have noted, before his criminal trial, the petitioner moved to
    suppress his confession, claiming that it was not voluntary. See footnote 1
    of this opinion. The court denied the motion to suppress. State v. Mercado,
    supra, 
    139 Conn. App. 101
     n.3. The petitioner subsequently testified before
    the jury that his written and videotaped statements ‘‘were not the truthful
    product of his free will,’’ and ‘‘[h]e agreed to sign the statements to provide
    the police with the information they wanted in order to end the police
    questioning.’’ 
    Id.
     The jury obviously did not credit his version of events. As
    the habeas court noted, ‘‘the petitioner makes no claim that [the evidence
    of his confession] was inadmissible evidence at his criminal trial.’’
    11
    In his voluntary statement to Lieutenant Wardwell, the petitioner
    claimed that he shot the victim with the .223 caliber AR-15 that the police
    seized from his house at the time of his arrest. He claimed that he used an
    adapter, which modified the AR-15 to allow it to shoot .22 caliber bullets.
    At the criminal trial, the unmodified AR-15 was entered into evidence as a
    full exhibit. The state’s firearms expert, Lieutenant Rainone, testified that,
    in its unmodified condition, the AR-15 was incapable of firing the .22 caliber
    bullet that killed the victim. Trial counsel did not call a firearms expert.
    At the petitioner’s habeas trial, Lieutenant Rainone again testified that
    the AR-15 admitted at the petitioner’s criminal trial, in its unmodified condi-
    tion, was incapable of firing the .22 caliber bullet that killed the victim. The
    petitioner presented the testimony of a firearms expert, Dr. Harper, who
    testified, consistent with Lieutenant Rainone’s testimony, that the AR-15
    admitted at the petitioner’s criminal trial was incapable of firing a .22 caliber
    bullet. He further testified that even if the AR-15 was modified to fire a .22
    caliber bullet, the two bullets recovered from the victim’s head and the
    petitioner’s backyard could not have been fired from the AR-15 in the condi-
    tion in which it was seized, unless the barrel was changed. Dr. Harper
    testified that, with respect to the issue of the murder weapon, he agreed
    with Lieutenant Rainone’s testimony that the AR-15 seized and entered into
    evidence at the petitioner’s criminal trial did not fire the .22 caliber bullet
    that killed the victim.
    When trial counsel was questioned about the admission of the AR-15 at
    the petitioner’s criminal trial, Attorney Eddy testified that trial counsel
    engaged a firearms expert, but that expert ‘‘came to the same conclusion
    as Lieutenant Rainone,’’ so trial counsel made the tactical decision to allow
    the state to introduce the AR-15. This allowed trial counsel to argue to the
    jury that the gun recovered from the petitioner’s home was not the murder
    weapon, even according to the state’s own expert. Attorney Simon testified
    that trial counsel hired a firearms expert, but that his opinions were ‘‘not
    particularly helpful.’’ He testified that he argued to the jury that the seized
    AR-15 was not the murder weapon, and that trial counsel thought that such
    an argument was ‘‘as good as it got’’ for the petitioner.
    12
    In support of his argument that his counsel’s deficient performance
    prejudiced him, the petitioner repeatedly cites to this court’s decision in
    State v. Coccomo, 
    115 Conn. App. 384
    , 
    972 A.2d 757
     (2009), rev’d, 
    302 Conn. 664
    , 
    31 A.3d 1012
     (2011). He contends that, in Coccomo, this court ‘‘over-
    turned a conviction on the basis that the prejudicial impact on the defendant
    of the evidence outweighed its probative value.’’
    In Coccomo, the defendant was convicted of three counts of manslaughter
    in the second degree with a motor vehicle, three counts of misconduct with
    a motor vehicle, and one count of operating a motor vehicle while under
    the influence of intoxicating liquor or drugs. State v. Coccomo, supra, 
    115 Conn. App. 385
    –86. On direct appeal, the defendant argued that the trial
    court improperly admitted consciousness of guilt evidence which was more
    prejudicial than probative. Id., 386, 401. This court agreed, and concluded
    that the trial court abused its discretion in admitting the challenged evidence,
    and that because the state’s case was not very strong, ‘‘the admission of
    the prejudicial evidence . . . likely tipped the scale in favor of the state.’’
    Id., 402. This court reversed the judgment of conviction and remanded the
    case for a new trial. Id.
    The petitioner’s reliance on Coccomo is misplaced for several reasons,
    the most obvious of which being that, on appeal to our Supreme Court,
    that court reversed the judgment of this court and remanded the case for
    affirmance of the judgment of conviction. State v. Coccomo, 
    302 Conn. 664
    ,
    697, 
    31 A.3d 1012
     (2011).
