    (SC 19024)

    on the brief, was William A. Adsit, assigned counsel,
    for the appellant (defendant).

    Opinion
    PALMER, J. The defendant, Dickie E. Anderson, Jr.,
    was charged in separate informations with the murders
    of Rene Pellegrino and Michelle Comeau in violation
    of General Statutes § 53a-54a (a). After the trial court
    granted the state’s motion to consolidate the cases
    based on the cross admissibility of the evidence, the
    jury found the defendant guilty of the murder of Pelle-
    grino but was unable to reach a verdict in the Comeau
    case. The trial court therefore declared a mistrial in
    that case and subsequently sentenced the defendant to
    sixty years imprisonment for the murder of Pellegrino.
    On appeal from the judgment of conviction in the Pelle-
    grino case,1 the defendant claims that the trial court
    abused its discretion in consolidating the cases for trial
    because the state had failed to meet its burden of estab-
    lishing either that the evidence was cross admissible
    or that the defendant would not be substantially preju-
    diced by the joinder. We disagree and, accordingly,
    affirm the judgment of the trial court.
    The following facts, which the jury reasonably could
    have found, and procedural history are relevant to our
    analysis of the defendant’s claims. On June 25, 1997, the
    police discovered the naked body of an adult Caucasian
    female in the travel portion of a rural roadway in the
    town of Waterford. The body had been posed, with
    knees bent, feet together and arms outstretched. No
    clothing or jewelry was found in the vicinity of the
    body. The victim was later identified as Pellegrino, a
    known prostitute from the New London area who
    recently had been released from prison. Pellegrino’s
    body was transported to the Office of the Chief Medical
    Examiner, where the medical examiner performing the
    autopsy determined her cause of death to be ‘‘asphyxia
    by neck compression,’’ with evidence of both manual
    and ligature strangulation. Pellegrino, who was seven-
    teen weeks pregnant at the time of her death, also
    had sustained occipital trauma, and her blood tested
    positive for cocaine. A vaginal swab taken from Pelle-
    grino contained DNA from an unknown male, which
    was subsequently entered into a national DNA database
    (DNA database). After several months, the investigation
    into the Pellegrino murder went cold.
    On May 1, 1998, the police located the naked body
    of another adult Caucasian female in the travel portion
    of a rural roadway in the town of Franklin, close to the
    Norwich line. The victim’s body was found with her
    arms and legs outstretched. The first witnesses to dis-
    cover the body reported seeing a vehicle parked next
    to the victim that sped off as the witnesses approached.
    No clothing or jewelry was found in the vicinity of the
    body. The decedent was later identified as Michelle
    Comeau, a convicted prostitute from the Norwich area
    who recently had been released from prison. The medi-
    cal examiner determined Comeau’s cause of death to
    be ‘‘asphyxia by neck compression,’’ with evidence of
    both manual and ligature strangulation. Comeau’s blood
    also tested positive for cocaine, and, like Pellegrino, she
    had sustained occipital trauma. As with the Pellegrino
    murder investigation, the investigation into Comeau’s
    murder went cold after several months.
    In 2008, authorities, through the DNA database,
    matched the unknown DNA from Pellegrino’s vaginal
    swab to the defendant, who subsequently was inter-
    viewed by the police. At first, the defendant denied
    knowing Pellegrino. After he was informed of the DNA
    match, however, the defendant admitted to having had
    sexual intercourse with Pellegrino the evening before
    and the morning of her death. According to the defen-
    dant, he gave Pellegrino crack cocaine in exchange for
    sex. Two witnesses, Arthur Moore and Toni Wilson,
    implicated the defendant in Pellegrino’s death. Moore,
    who was the defendant’s cellmate at Osborne Correc-
    tional Institution, reported to the police that the defen-
    dant told him that he had strangled a woman named
    Rene at his sister’s house after having sex with her
    because the woman was being loud and demanding
    money. According to Moore, the defendant told him
    that he left the woman’s body on a road in Waterford
    and that he would not have killed her if he had known
    that she was pregnant. Wilson, the defendant’s former
    girlfriend and the mother of two of his children,
    informed the police that, in 1998, in a very emotional
    state, the defendant had confessed to killing a woman
    after having sex with her. According to Wilson, the
    woman had demanded payment for the sexual encoun-
    ter, and the defendant did not want to pay, so they
    fought, and he killed her.
    When questioned about the Comeau murder, the
    defendant initially denied knowing Comeau but eventu-
    ally admitted that she had been a frequent visitor at the
    home of his father, Dickie Anderson, Sr., in the city of
    Norwich, and that, on the day of her death, he had
    exposed his penis to her in a bathroom at his father’s
    house. The defendant described himself to the police
    as a ‘‘trick artist’’ who traded crack cocaine for sex
    with prostitutes. The defendant denied killing Comeau,
    however, or ever having had sexual intercourse with
    her. Two witnesses, Tanya Anderson, the defendant’s
    sister, and Moore, the defendant’s former cellmate,
    implicated the defendant in Comeau’s murder. Moore
    reported to the police that the defendant had told him
    that a woman with whom he was having sexual relations
    overdosed on drugs while they were together and that
    he disposed of her body in Franklin. Tayna Anderson
    reported to the police that, after Comeau’s murder, the
    defendant told her that he had been sexually intimate
    with a woman whose body was found on a road in
    Norwich and that he had met the woman at their
    father’s house.
    On June 1, 2010, the defendant was arrested and
    charged in an information with the murder of Pelle-
    grino. On September 1, 2010, the defendant was charged
    in a separate information with the murder of Comeau.
    On November 21, 2011, the defendant filed a motion
    for a speedy trial in the Comeau case, and, shortly
    thereafter, on December 3, 2011, the state filed a motion
    to consolidate the cases based, in part, on the cross
    admissibility of the evidence. In a memorandum of law
    in support of its motion, the state argued, inter alia,
    that the evidence would be cross admissible to prove
    the identity of the killer based on the signature nature
    of the crimes and to show a common scheme or plan.
    Specifically, the state maintained that the murders
    shared a sufficient number of unique characteristics to
    support an inference that the same person had commit-
    ted both crimes in furtherance of an overall plan,
    namely, ‘‘to murder prostitutes and display their dead
    bodies for others to find.’’
    With respect to the signature nature of the crimes,
    the state’s memorandum of law set forth twenty-nine
    similarities between the murders, which may be sum-
    marized as follows: the crimes took place ten months
    apart in New London County during warm weather
    months; the victims’ naked bodies were found in the
    travel portion of a rural roadway approximately fifteen
    miles apart; the victims knew each other; there was
    evidence of posing in both cases; both victims were
    Caucasian and had dark hair; both victims were prosti-
    tutes who had recently been released from prison; no
    clothing or jewelry was found in the vicinity of either
    body; both victims were known to use crack cocaine
    and had cocaine in their blood at the time of death;
    both victims resided in New London County; both vic-
    tims knew the defendant; both victims were killed on
    a week night; both victims were killed in a location
    other than where their bodies were discovered; both
    victims were strangled with a ligature; both victims
    sustained occipital trauma; and the defendant admitted
    to having sexual encounters with both victims on the
    day of their murders.
    In an oral ruling following a hearing on the state’s
    motion for consolidation, the trial court granted the
    motion. Thereafter, the court granted the defendant’s
    motion for articulation of the ruling and issued a memo-
    randum of decision explaining its reasons for consol-
    idating the cases. In its memorandum of decision, the
    court stated that joinder was appropriate under the
    factors set forth in State v. Boscarino, 
    204 Conn. 714
    ,
    720–24, 
    529 A.2d 1260
    (1987),2 because the cases
    involved easily distinguishable factual scenarios, the
    trial would not be long or overly complex, and the
    allegations in both cases, although serious, were not
    so shocking or brutal that there was any risk that one
    case would be tainted by the shocking or brutal nature
    of the other. The court further concluded that joinder
    was also appropriate because the evidence was cross
    admissible to prove the defendant’s identity based on
    the signature nature of the crimes. In support of this
    conclusion, the court explained that ‘‘[e]ach of the char-
    acteristics of the crimes, when viewed in isolation,
    [was] not necessarily distinctive. When viewed as a
    whole, however, the characteristics reveal[ed] a distinc-
    tive combination of factors, one that strongly sug-
    gest[ed] a modus operandi inherent in the activities of
    but one perpetrator.’’
    On January 16, 2012, the defendant filed a motion to
    sever the trials in light of this court’s then recent deci-
    sion in State v. Payne, 
    303 Conn. 538
    , 
    34 A.3d 370
    (2012),3 in which we overruled our prior case law adopt-
    ing a presumption in favor of joinder in criminal cases
    and imposed on the state the burden of establishing
    either that the evidence was cross admissible or that
    the defendant would not be unduly prejudiced by join-
    der upon application of the Boscarino factors. See 
    id., 547–50. At
    the hearing on the defendant’s motion to
    sever, defense counsel argued that Payne required the
    court to conduct an adversarial hearing, similar to a
    suppression hearing, at which the state would be
    required to prove by a preponderance of the evidence
    that the evidence was cross admissible. The trial court
    rejected this contention, stating that Payne did not ‘‘in
    any way indicate that [the court] needs [to hold] an
    evidentiary hearing before it can [join cases for trial].
    . . . I see nothing in the case that mandates an eviden-
    tiary hearing. It would be virtually a trial before a trial.’’
    The court further stated that, although Payne had elimi-
    nated the presumption in favor of joinder, there was
    nothing in Payne to suggest that this court intended to
    alter the customary procedure by which joinder ordi-
    narily occurs, which, the court observed, the state had
    followed in the present case by filing a memorandum
    of law and an accompanying offer of proof in support
    of its motion for consolidation. The court therefore
    concluded: ‘‘Clearly, the presumption of joinder no
    longer exist[s] [after] . . . Payne . . . . Payne . . .
    expressly state[s] that . . . on a motion [for] join[der],
    the state has the burden . . . to show by a preponder-
    ance of the evidence either that the evidence in the
    case is cross admissible or that the defendant would
    not be unfairly prejudiced in regard to the Boscarino
    factors. I’ll state for the record that [the] court has
    found that the state has, in fact, by a preponderance
    of the evidence, established both that the evidence is
    cross admissible and that there is no unfair prejudice
    in regard to the Boscarino factors.’’
    After a joint trial of both the Comeau and Pellegrino
    cases, the jury found the defendant guilty of the Pelle-
    grino murder but could not reach a verdict in the Com-
    eau case. The trial court rendered judgment in accor-
    dance with the jury verdict in the Pellegrino case and
    declared a mistrial in the Comeau case.
    On appeal from the judgment of conviction in the
    Pellegrino case, the defendant claims that the trial court
    failed to hold the state to its burden, under State v.
    
    Payne, supra
    , 
    303 Conn. 547
    –50, of establishing either
    that the evidence in the two cases was cross admissible
    or that the defendant would not be unduly prejudiced
    by joinder of the cases under the Boscarino factors.
    Although the defendant’s claim with respect to the cross
    admissibility issue is not crystal clear, he appears to
    argue that the state was required but failed to adduce
    actual testimony to provide a proper evidentiary basis
    for its offer of proof. The defendant argues that, instead
    of making such a showing, the state submitted a memo-
    randum of law containing ‘‘[a] laundry list of alleged
    similarities between the two cases,’’ unsupported by
    any testimony or evidence, and, further, that the trial
    court should not have treated that submission as a
    ‘‘legitimate’’ offer of proof. We agree with the state that
    its offer of proof was sufficient for purposes of its claim
    that the evidence was cross admissible and that the
    trial court did not abuse its discretion in granting the
    state’s motion for consolidation on the basis of the
    cross admissibility of the evidence. We therefore need
    not engage in an evaluation of the Boscarino factors.
    We first address the defendant’s contention that the
    trial court improperly treated the state’s memorandum
    of law in support of its motion for consolidation as an
    offer of proof for purposes of deciding that motion.
    We previously have stated that ‘‘[o]ffers of proof are
    allegations by the attorney . . . in which he represents
    to the court that he could prove them if granted an
    evidentiary hearing. . . . The purpose of an offer of
    proof has been well established by our courts. First, it
    informs the court of the legal theory under which the
    evidence is admissible. Second, it should inform the
    trial [court] of the specific nature of the evidence so that
    the court can judge its admissibility. Third, it creates a
    record for appellate review. . . . Additionally, an offer
    of proof should contain specific evidence rather than
    vague assertions and sheer speculation.’’ (Citation omit-
    ted; internal quotation marks omitted.) State v. Marti-
    nez, 
    295 Conn. 758
    , 771, 
    991 A.2d 1086
    (2010). As we
    previously indicated, in its memorandum of law the
    state identified twenty-nine factual similarities between
    the two murders, which it argued were sufficiently
    unusual and distinctive as to warrant a reasonable infer-
    ence that the same person had committed both crimes.
    Contrary to the defendant’s contention, these alleged
    similarities were not ‘‘vague assertions’’ based on ‘‘sheer
    speculation.’’ Indeed, a review of the record reveals
    that all of the allegations were taken directly from the
    arrest warrant affidavits in both cases and that those
    affidavits set forth in considerable detail the evidence
    that the police had collected over the course of their
    nearly ten year investigation into the murders of both
    Pellegrino and Comeau, including the medical examin-
    er’s findings, crime scene evidence, witness statements,
    and the defendant’s own incriminating statements. This
    information, together with the state’s arguments in sup-
    port of joinder, was more than sufficient to apprise the
    court of the specific nature of the evidence that the
    state intended to present at trial, and why, in the state’s
    view, the evidence in the two cases was, in fact,
    cross admissible.
    To the extent that the defendant contends that an
    offer of proof to establish cross admissibility under
    Payne must be presented by way of an evidentiary
    hearing at which the state presents actual testimony,
    we reject that claim. As we have explained, ordinarily,
    an offer of proof, although evidentiary in nature, may
    consist of statements or submissions by counsel, and
    that approach was fully adequate for purposes of the
    present case. Of course, if a defendant were to call into
    question the factual validity of the state’s offer of proof,
    the trial court would be required to address the disputed
    issue and, if the court deemed it necessary to resolve
    the dispute, conduct an evidentiary hearing for that
    purpose. No such factual challenge to the state’s offer
    of proof, however, occurred in the present case.4
    We turn, therefore, to the defendant’s claim that the
    trial court abused its discretion in granting the state’s
    motion for consolidation because the state failed to
    demonstrate that the evidence was cross admissible.
    The following legal principles guide our analysis of this
    claim. ‘‘[I]n deciding whether to [join informations] for
    trial, the trial court enjoys broad discretion, which, in
    the absence of manifest abuse, an appellate court may
    not disturb.’’ (Internal quotation marks omitted.) State
    v. LaFleur, 
    307 Conn. 115
    , 158, 
    51 A.3d 1048
    (2012).
    ‘‘[W]hen charges are set forth in separate informations,
    presumably because they are not of the same character,
    and the state has moved in the trial court to join the
    multiple informations for trial, the state bears the bur-
    den of proving that the defendant will not be substan-
    tially prejudiced by joinder pursuant to Practice Book
    § 41-19.’’ State v. 
    Payne, supra
    , 
    303 Conn. 549
    –50. On
    appeal, however, the burden shifts to the defendant ‘‘to
    show that joinder was improper by proving substantial
    prejudice that could not be cured by the trial court’s
    instructions to the jury . . . .’’ (Internal quotation
    marks omitted.) State v. 
    LaFleur, supra
    , 158.
    In Payne, ‘‘[t]his court . . . revisited the principles
    that govern our review of a trial court’s ruling on a
    motion for joinder. As we clarified in [Payne], a trial
    court’s ruling on a motion for joinder of multiple infor-
    mations for trial implicates Practice Book § 41-19 . . .
    [which] provides that [t]he judicial authority may, upon
    its own motion or the motion of any party, order that
    two or more informations, whether against the same
    defendant or different defendants, be tried together. A
    long line of cases establishes that the paramount con-
    cern is whether the defendant’s right to a fair trial will
    be impaired. Therefore, in considering whether joinder
    is proper, this court has recognized that, [when] evi-
    dence of one incident would be admissible at the trial
    of the other incident, separate trials would provide the
    defendant no significant benefit. . . . Under such cir-
    cumstances, the defendant would not ordinarily be sub-
    stantially prejudiced by joinder of the offenses for a
    single trial. . . . Accordingly, we have found joinder
    to be proper [when] the evidence of other crimes or
    uncharged misconduct [was] cross admissible at sepa-
    rate trials. . . . [When] evidence is cross admissible,
    therefore, our inquiry ends.’’ (Citations omitted; foot-
    note omitted; internal quotation marks omitted.) 
    Id., 154–55; see
    also State v. Crenshaw, 
    313 Conn. 69
    , 84,
    
    95 A.3d 1113
    (2014) (‘‘[w]e consistently have found join-
    der to be proper if we have concluded that the evidence
    of other crimes or uncharged misconduct would have
    been cross admissible at separate trials’’ [internal quota-
    tion marks omitted]).
    ‘‘As a general rule, evidence of guilt of other crimes
    is inadmissible to prove that a defendant is guilty of
    the crime charged against him. . . . The rationale of
    this rule is to guard against its use merely to show
    an evil disposition of an accused, and especially the
    predisposition to commit the crime with which he is
    now charged. . . . The fact that such evidence tends
    to prove the commission of other crimes by an accused
    does not render it inadmissible if it is otherwise relevant
    and material. . . . Such evidence is admissible for
    other purposes, such as to show intent, an element
    [of] the crime, identity, malice, motive or a system of
    criminal activity. . . .
    ‘‘Our analysis of whether evidence of the uncharged
    misconduct is admissible is two-pronged. First, the evi-
    dence must be relevant and material to at least one of
    the circumstances encompassed by the exceptions to
    the propensity rule. Second, the probative value of such
    evidence must outweigh the prejudicial effect of the
    other crimes evidence.’’ (Citations omitted; internal
    quotation marks omitted.) State v. Figueroa, 
    235 Conn. 145
    , 161–62, 
    665 A.2d 63
    (1995).
    ‘‘The first threshold for the use of evidence of other
    crimes or misconduct on the issue of identity is that
    the methods used be sufficiently unique to warrant a
    reasonable inference that the person who performed
    one misdeed also did the other. . . . [I]n proffering
    other crime evidence [t]o prove other like crimes by
    the accused so nearly identical in method as to earmark
    them as the handiwork of the accused . . . much more
    is demanded than the mere repeated commission of
    crimes of the same class, such as repeated burglaries
    or thefts. The device used must be so unusual and
    distinctive as to be like a signature. . . . In order to
    determine if this threshold criterion for admissibility
    has been met, [the court] must examine the proffered
    evidence and compare it to the charged offenses.’’ (Cita-
    tions omitted; internal quotation marks omitted.) 
    Id., 163. Applying
    these principles to the present case, we
    have no hesitation in concluding that the trial court did
    not abuse its discretion in joining the Pellegrino and
    Comeau cases for trial based on the cross admissibility
    of the evidence in each case. The similarities between
    the victims (both women were prostitutes and drug
    users), the geographic and temporal proximity of the
    murders (the crimes were committed ten months apart
    within a fifteen miles radius), the victims’ cause of death
    (both women were strangled manually and with a liga-
    ture), and the extremely unusual and degrading manner
    in which the victims’ bodies were disposed of after
    death (completely naked in the travel portion of a rural
    roadway), are, standing alone, distinctive enough char-
    acteristics to warrant an inference that the same person
    committed both crimes. Indeed, what the killer did with
    the victims’ bodies after the murders—placing them in
    the middle of a road in the apparent hope that they
    would be discovered immediately—is itself sufficiently
    unusual as to suggest a type of signature. In addition, H.
    Wayne Carver II, the chief medical examiner, testified at
    trial that, out of the more than 6000 autopsies he has
    performed or supervised in his career, he could recall
    only three cases in which the victims presented with
    evidence of both manual and ligature strangulation, and
    the Pellegrino and Comeau murders were two of those
    cases. Moreover, Edward T. McDonough, the former
    deputy chief medical examiner and the medical exam-
    iner who performed the autopsies on both Pellegrino
    and Comeau, similarly testified that the Pellegrino and
    Comeau murders were the only cases he could recall
    that had involved both manual and ligature strangu-
    lation.
    As the state maintains, however, numerous other
    commonalities bring into sharp relief the signature
    nature of the crimes. As we previously indicated, both
    women were murdered shortly after being released
    from prison, both women were killed in a location other
    than where their bodies were found, both women sus-
    tained occipital trauma, both women had ingested
    cocaine immediately prior to death, no clothing or jew-
    elry was found in the vicinity of either body, there was
    evidence that both women frequented the home of the
    defendant’s father, and the defendant admitted to hav-
    ing had a sexual encounter with each victim on the
    day of each murder. These additional factors, when
    considered together with the aforementioned factors,
    underscore the propriety of the trial court’s decision
    to join the cases for trial.
    Accordingly, we find no merit in the defendant’s con-
    tention that the trial court abused its discretion in join-
    ing the cases for trial because some of the similarities
    between the murders—for example, both women were
    prostitutes, both women used crack cocaine, and both
    women resided in New London County—were not suffi-
    ciently unique or distinctive as to warrant an inference
    that the murders were committed by the same person.
    Indeed, even if we agreed with the defendant’s charac-
    terization of this evidence as commonplace, ‘‘[t]he fact
    that some of the similarities between the offenses [are]
    . . . relatively common occurrences when standing
    alone does not . . . negate the uniqueness of the
    offenses when viewed as a whole. It is the distinctive
    combination of actions [that] forms the signature or
    modus operandi of the crime . . . and it is this criminal
    logo [that] justifies the inference that the individual
    who committed the first offense also committed the
    second.’’ (Citations omitted; internal quotation marks
    omitted.) State v. 
    Figueroa, supra
    , 
    235 Conn. 164
    . We
    therefore conclude that, even though some of the
    shared characteristics of the murders were not espe-
    cially unique when viewed in isolation, the distinctive
    combination of elements fully justified an inference that
    the same person had committed both crimes.
    We also find no merit in the defendant’s contention
    that the trial court abused its discretion in consolidating
    the cases because many of the alleged similarities were
    not proven at trial. Specifically, the defendant argues
    that it was never proven that Pellegrino and Comeau
    knew one another, that Comeau knew the defendant,
    that Comeau’s body was posed or in the process of
    being posed at the time of discovery, that the murders
    occurred in warm weather months, that the bodies were
    discovered in rural areas, or that the victims both had
    dark hair. We do not agree with the defendant’s charac-
    terization of the evidence presented at trial. As the state
    maintains, and as a review of the record confirms, the
    state adduced evidence of all but two of the alleged
    similarities, namely, that the victims knew one another
    and that they had dark hair.5 But even if the state’s
    evidence fell short in some respects, it would not alter
    our conclusion regarding the propriety of the trial
    court’s decision to join the cases for trial because, as we
    recently have explained in addressing a similar claim, ‘‘it
    is well established that the trial court, in making the
    discretionary, pretrial decision to join multiple cases,
    rules on whether the evidence could be admissible, not
    whether the evidence actually is admitted. . . .
    Because the decision to join two cases occurs prior to
    the introduction of evidence, the trial court must make
    its decision on the basis of potential admissibility rather
    than what actually transpires at trial. It would not make
    sense for a reviewing court to overturn the trial court’s
    discretionary, pretrial decision to consolidate solely on
    the ground that the parties did not ultimately introduce
    the evidence at trial.’’ (Citation omitted; emphasis omit-
    ted.) State v. 
    Crenshaw, supra
    , 
    313 Conn. 89
    . Similarly,
    it would make no sense for this court to set aside a
    trial court’s pretrial decision to consolidate solely
    because the state ultimately failed to prove some of the
    facts alleged to be cross admissible when the evidence
    that was adduced was sufficient to support the determi-
    nation that the evidence was cross admissible.
    We also disagree with the defendant that the trial
    court abused its discretion in joining the cases for trial
    because some of the alleged similarities were duplica-
    tive of one another. Specifically, the defendant argues
    that the state’s separate allegations that the homicides
    took place approximately fifteen miles apart, that they
    took place in the same county, and that both victims
    resided in New London County, are really just another
    way of saying that the homicides occurred in ‘‘roughly
    the same geographic area.’’ (Internal quotation marks
    omitted.) The defendant also argues that the allegations
    that both victims ‘‘ ‘were known to use crack cocaine’ ’’
    and ‘‘ ‘had cocaine in their blood when their bodies
    were found’ ’’ are also duplicative because ‘‘the use of
    cocaine . . . [is] a necessary condition of . . . having
    cocaine in one’s system . . . .’’ We do not agree that
    these allegations are duplicative. As the state maintains,
    it does not necessarily follow that a victim who uses
    crack cocaine will also have cocaine in her system at
    the time of her death. The fact that she does, however,
    is relevant not only for what it reveals about the victim’s
    drug habits, but also for what it reveals about the modus
    operandi of the killer, in particular, the methods he may
    use to target or lure his victims. Similarly, the fact that
    both Pellegrino’s and Comeau’s bodies were found
    approximately fifteen miles apart and the fact that they
    both resided and were killed in New London County
    are not necessarily duplicative in the context of proving
    a signature crime. Although these facts may seem to
    support but a single proposition concerning geographic
    proximity, each one adds to the distinctive mosaic of
    common occurrences that ultimately combine to justify
    the inference of a signature crime. Finally, even if we
    were to agree that one or more of the allegations con-
    tained in the state’s offer of proof were duplicative,
    the other nonduplicative allegations were sufficient to
    justify an inference of modus operandi. Accordingly,
    the defendant cannot prevail on his claim that the trial
    court abused its discretion in consolidating the Pelle-
    grino and Comeau cases for trial on the basis of the
    cross admissibility of the evidence in the two cases.6
    The judgment is affirmed.
    In this opinion the other justices concurred.

    The defendant appealed directly to this court from the judgment of the
    trial court pursuant to General Statutes § 51-199 (b).

    In Boscarino, this court ‘‘identified several factors that a trial court
    should consider in deciding whether a severance [or denial of joinder]
    may be necessary to avoid undue prejudice resulting from consolidation of
    multiple charges for trial. These factors include: (1) whether the charges
    involve discrete, easily distinguishable factual scenarios; (2) whether the
    crimes were of a violent nature or concerned brutal or shocking conduct
    on the defendant’s part; and (3) the duration and complexity of the trial.
    . . . If any or all of these factors are present, a reviewing court must decide
    whether the trial court’s jury instructions cured any prejudice that might
    have occurred.’’ (Internal quotation marks omitted.) State v. LaFleur,

    Although our decision in Payne was officially released on January 24,
    2012, and the defendant filed his motion, which was based on that decision,
    one week earlier, on January 17, 2012, a preliminary version of our decision
    in Payne had been released to the public on the Judicial Branch website
    on or before January 17, 2012.
    4
    In Payne, we explained that the state must ‘‘prov[e], by a preponderance
    of the evidence,’’ either that the evidence is cross admissible or that the
    defendant will not be unfairly prejudiced in accordance with Boscarino.
    State v. 
    Payne, supra
    , 
    303 Conn. 550
    . The defendant suggests that this
    language supports his contention that an evidentiary hearing is required
    whenever the state seeks to join multiple informations for trial. The defen-
    dant misapprehends our holding in Payne, in which we concluded only that
    the state bears the burden of establishing that joinder is proper. See 
    id. 5 We
    note, however, that there was evidence that both Pellegrino and
    Comeau had frequented the home of the defendant’s father.
    6
    We note that the defendant also claims that the trial court improperly
    denied his motion to dismiss in the Comeau case for lack of a speedy trial.
    As we previously indicated, the trial court declared a mistrial in the Comeau
    case after the jury was unable to reach a verdict in that case. Although
    neither party has raised the issue of whether the trial court’s denial of the
    defendant’s motion to dismiss constitutes a final judgment for purposes of
    appeal, we must address the issue because it implicates this court’s subject
    matter jurisdiction. See, e.g., State v. Curcio, 
    191 Conn. 27
    , 30, 
    463 A.2d 566
    (1983) (‘‘[b]ecause our jurisdiction over appeals . . . is prescribed by stat-
    ute, we must always determine the threshold question of whether the appeal
    is taken from a final judgment before considering the merits of the claim’’).
    It is well established that ‘‘[t]he principal statutory prerequisite to invoking
    our jurisdiction is that the ruling from which an appeal is sought must
    constitute a final judgment. See General Statutes §§ 51-197a and 52-263.
    . . . We cannot hear appeals from preliminary rulings of the trial court
    . . . . Piecemeal appeals, particularly in criminal proceedings, are not only
    outside [of] our jurisdiction, but also contravene the long-standing case law
    of this state and the United States.’’ (Internal quotation marks omit-
    ted.) State v. Rhoads, 
    122 Conn. App. 238
    , 243, 
    999 A.2d 1
    , cert. denied, 
    298 Conn. 913
    , 
    4 A.3d 836
    (2010). Moreover, it is well established that, ‘‘[i]n a
    criminal proceeding, there is no final judgment until the imposition of a
    sentence.’’ (Emphasis omitted; internal quotation marks omitted.) 
    Id. This court
    previously has recognized that the denial of a motion to dismiss for
    lack of a speedy trial is not a final judgment for purposes of appeal. See, e.g.,
    State v. Fielding, 
    296 Conn. 26
    , 36, 
    994 A.2d 96
    (2010); State v. Spendolini, 
    189 Conn. 92
    , 93, 
    454 A.2d 720
    (1983); State v. Lloyd, 
    185 Conn. 199
    , 207, 
    440 A.2d 867
    (1981). Although some narrowly defined exceptions to the final
    judgment rule exist in the civil context, ‘‘[w]e have been disinclined . . .
    to extend the privilege of an interlocutory appeal in criminal cases beyond
    the double jeopardy circumstance. This reluctance stems principally from
    our concern that to allow such appeals would greatly delay the orderly
    progress of criminal prosecutions in the trial court . . . .’’ (Internal quota-
    tion marks omitted.) State v. Alvarez, 
    257 Conn. 782
    , 796, 
    778 A.2d 938
    (2001). In the present case, the defendant does not explain why he is entitled
    to review of his speedy trial claim in the absence of a final judgment in the
    Comeau case, and, accordingly, we adhere to our prior practice of declining
    to review such claims for want of subject matter jurisdiction.
    We note, however, that the defendant also argues that the alleged speedy
    trial violation in the Comeau case caused him prejudice in the Pellegrino
    case, presumably because, if there had been no such purported speedy trial
    violation, the cases would have been tried separately, and, consequently,
    the jury in the Pellegrino case would never have learned about the Comeau
    murder. The defendant’s argument fails to account for the fact that the cases
    were tried together because the evidence would have been cross admissible
    if they had been tried separately. Accordingly, even if there was a speedy
    trial violation in the Comeau case, it could not possibly have prejudiced the
    defendant in the Pellegrino case because the evidence relating to Comeau’s
    murder nevertheless would have been admissible in the Pellegrino case. Cf.
    State v. 
    Crenshaw, supra
    , 
    313 Conn. 89
    (when evidence is cross admissible,
    joinder does not prejudice defendant ‘‘as the proper remedy for improper
    joinder is the granting of two new, separate trials, during which the parties
    ostensibly would be free to introduce the contested evidence in both cases
    in any event’’).
