    SUMMARY
    March 7, 2019
    2019COA30
    No. 16CA0750, People v. Gonzales — Evidence — Requirement
    of Authentication or Identification — Audio Recordings
    In a case involving the submission of a voicemail as evidence,
    the division addresses the standards for authenticating an audio
    recording under CRE 901 and declines to follow People v. Baca,
    
    2015 COA 153
    , to the extent that it purports to establish an
    exclusive rule for the authentication of a voice recording.
    The division concludes that CRE 901, which governs the
    authentication of evidence in Colorado courts, requires a flexible,
    factual inquiry to determine under the facts of each case whether a
    reasonable jury could determine that the proffered evidence is what
    its proponent claims. The division states that, in making this
    determination, the trial court necessarily has broad discretion to
    consider a variety of factors and circumstances and must consider
    all relevant circumstances that bear on whether a recording is what
    it purports to be.
    Applying this analysis, the division concludes that the trial
    court did not abuse its discretion in admitting the contested
    voicemail.
    The division also concludes that the trial court did not abuse
    its discretion in admitting a photograph of the defendant’s bare
    torso and arms that showed the defendant’s tattoos.

    for Plaintiff-Appellee
    Megan A. Ring, Colorado State Public Defender, Karen N. Taylor, Deputy State
    Public Defender, Denver, Colorado, for Defendant-Appellant
    ¶1    This case addresses the standards for authenticating an audio
    recording under CRE 901. Defendant, Daniel J. Gonzales, appeals
    his convictions for first degree murder with intent and after
    deliberation, first degree felony murder, abuse of a corpse, stalking,
    arson, burglary, and aggravated robbery. He claims that the trial
    court did not comply with the authentication rules prescribed by a
    division of this court in People v. Baca, 
    2015 COA 153
    , when it
    admitted a voicemail purportedly left by Gonzales for his murder
    victim.
    ¶2    We reject Gonzales’s claim because, to the extent Baca
    purports to establish an exclusive rule for the authentication of a
    voice recording, we decline to follow it. We also conclude that when
    the flexible principles of authentication set forth in CRE 901 are
    applied, the voicemail was properly authenticated. Finally, we
    conclude that the trial court properly admitted a photograph
    depicting him shirtless, which exhibited two tattoos on his arms.
    Having rejected all of Gonzales’s claims on appeal, we affirm.
    I.    Relevant Facts and Procedural History
    ¶3    The evidence admitted at trial, particularly the full confession
    Gonzales made to the police, established the following facts.
    1
    Gonzales grew up down the street from the victim and from a young
    age was sexually attracted to the victim. When he was about
    eighteen, Gonzales and a friend broke into the victim’s house. The
    friend stole a TV and a VCR while Gonzales hunted for clues in the
    house that the victim was gay. Gonzales also stole some of the
    victim’s clothing.
    ¶4    Gonzales eventually moved away from the victim’s
    neighborhood, but his interest in the victim did not disappear.
    Years later, Gonzales returned to the victim’s house, breaking in
    through the back door. After gaining entry, Gonzales grabbed a
    large knife from the kitchen and waited a substantial period of time
    for the victim to return. When he did, Gonzales repeatedly stabbed
    him in the neck, killing him. Gonzales then sexually assaulted the
    victim’s dead body and attempted, unsuccessfully, to set the house
    on fire to destroy the evidence. Gonzales fled the scene with a
    credit card, debit card, and cash that he had taken from the
    victim’s wallet. He was arrested a short time later in Florida.
    ¶5    At trial, the prosecution presented a video recording of
    Gonzales’s confession, as well as other evidence. The jury convicted
    Gonzales of all charges, the court sentenced him to life in prison
    2
    without the possibility of parole plus forty-eight years, and he now
    appeals.
    II.   The Trial Court Did Not Abuse Its Discretion When It Admitted
    the Voicemail
    ¶6     Gonzales first argues that the trial court erred in admitting a
    voicemail allegedly left by Gonzales for the victim because the
    prosecution did not properly authenticate the recording of the
    voicemail under the test set out in Baca, ¶ 30.
    ¶7     We review a trial court’s evidentiary rulings for an abuse of
    discretion. Davis v. People, 
    2013 CO 57
    , ¶ 13. A trial court abuses
    its discretion if its ruling is manifestly arbitrary, unreasonable, or
    unfair, or if its ruling is based on an erroneous view of the law.
    People v. Hard, 
    2014 COA 132
    , ¶ 22.
    A.   Additional Factual Background
    ¶8     After the police completed their crime scene analysis, the
    victim’s sister went to the house to put the victim’s affairs in order.
    She found a microcassette audiotape along with documents related
    to an earlier burglary of the victim’s house. On the tape, a man
    says that he has the victim’s pajamas and jeans. He also says that
    he is going to return those items to the victim, but not the other
    3
    items that were stolen. The sister listened to the tape and,
    recognizing its value, gave it to the police.
    ¶9     At trial, one of the detectives who had interviewed Gonzales
    after his arrest testified that he had also watched the video of that
    interview and had compared Gonzales’s voice in the interview to the
    voice on the tape. The detective testified that the voice on the tape
    sounded like Gonzales’s voice. On that basis, the prosecutor
    argued that the tape recording had been properly authenticated.
    Gonzales objected to the admission of the tape recording of the
    voicemail on authentication grounds, but the trial court overruled
    the objection.
    B.    Analysis
    ¶ 10   In Baca, a division of this court held that
    [i]f no witness with independent knowledge of
    the content of the [recording] can verify the
    accuracy of the recorded conversation, the
    proponent must instead present a witness who
    can verify the reliability of the recording
    process, by establishing the factors laid out in
    Alonzi: the competency of the recorder, the
    reliability of the recording system, the absence
    of any tampering with the recording, and the
    identification of the speakers.
    4
    Baca, ¶ 30 (citing Alonzi v. People, 
    198 Colo. 160
    , 163, 
    597 P.2d 560
    , 562 (1979)). In so doing, the division appears to have
    established an exclusive rule, regardless of the factual
    circumstances presented, to authenticate an audio recording. 1
    ¶ 11    In devising its exclusive test for the authentication of an audio
    recording, the division relied on the Colorado Supreme Court’s
    Alonzi decision (and other authorities) that predated the supreme
    court’s adoption of the Colorado Rules of Evidence. Baca, ¶¶ 26-28,
    30.
    ¶ 12    The Attorney General argues that Baca was wrongly decided
    and is inconsistent with the language and underlying purpose of
    CRE 901. To the extent that Baca holds that the only way an audio
    ———————————————————————
    1 In People in Interest of M.V., 
    2018 COA 163
    , a different division of
    this court relied, in part, on People v. Baca, 
    2015 COA 153
    , to
    determine whether a video recording was authentic.
    5
    recording can be authenticated is to meet one of the two
    alternatives stated in Baca, 2 we agree with the Attorney General.3
    1.   CRE 901 Does Not Prescribe Exclusive Tests for the
    Authentication of Evidence; Instead, CRE 901 Requires Trial
    Courts to Consider All the Circumstances Surrounding the
    Evidence
    ¶ 13   “The burden to authenticate ‘is not high — only a prima facie
    showing is required,’ and ‘a district court’s role is to serve as a
    gatekeeper in assessing whether the proponent has offered a
    satisfactory foundation from which the jury could reasonably find
    that the evidence is authentic.’” People v. Glover, 
    2015 COA 16
    ,
    ———————————————————————
    2 Even if Baca’s holding is tethered to its specific facts — a jailhouse
    telephone recording offered by a defendant in a criminal case — it
    may be too broad. As the present case well illustrates, there will be
    innumerable factual situations that are impossible to anticipate in
    which the Baca test may prove too rigid. We cannot exclude the
    possibility that there will exist some factual circumstances that
    would provide sufficient authentication of a jailhouse recording
    without meeting the requirements of Baca.
    3 Our holding creates a division split on this question. Unless and
    until the supreme court resolves the division conflict, the district
    courts may choose which of the conflicting decisions of the court of
    appeals to follow. See C.A.R. 35(e) (“Opinions designated for official
    publication must be followed as precedent by all lower court judges
    in the state of Colorado.”); see also People v. Valdez, 
    2014 COA 125
    ,
    ¶ 27 (stating that when the law is unsettled, in this case because of
    a split among divisions of the court of appeals, the trial court’s
    alleged error with respect to the law cannot constitute plain error).
    6
    ¶ 13 (quoting United States v. Hassan, 
    742 F.3d 104
    , 133 (4th Cir.
    2014)).
    ¶ 14   CRE 901, not common law decisions that predate the adoption
    of the Colorado Rules of Evidence, governs the authentication of
    evidence in Colorado courts. See People v. Ramirez, 
    155 P.3d 371
    ,
    374-75 (Colo. 2007) (The Colorado Rules of Evidence “govern the
    admissibility of expert testimony”; prior to the adoption of these
    rules, “admissibility of expert testimony was governed by common
    law.”).
    ¶ 15   There is only one rule stated in CRE 901. “The requirement of
    authentication or identification as a condition precedent to
    admissibility is satisfied by evidence sufficient to support a finding
    that the matter in question is what its proponent claims.” CRE
    901(a). The balance of CRE 901 is a series of “illustrations,” not
    black-letter rules. Subsection (b) explicitly states that the examples
    given are “[b]y way of illustration only, and not by way of
    limitation.”
    ¶ 16   Notably, one such illustration states that “[i]dentification of a
    voice, whether heard firsthand or through mechanical or electronic
    transmission or recording, by opinion based upon hearing the voice
    7
    at any time under circumstances connecting it with the alleged
    speaker” is consistent with the authentication requirements in CRE
    901(a). CRE 901(b)(5). In our view, this illustration does not
    establish that a voice recording can always be authenticated by a
    voice identification alone. 4 But this illustration, along with the
    others included in CRE 901(b), does demonstrate that the relevant
    considerations in authenticating a voice recording are not limited to
    those set out in Baca.
    ¶ 17   The Baca division relied heavily on a decision by the Colorado
    Supreme Court that predated the adoption of the Colorado Rules of
    Evidence. Baca, ¶¶ 26-27, 29 (citing Alonzi, 198 Colo. at 163, 
    597 P.2d at 562
    ). Alonzi, in turn, “note[d] with approval the test set out
    in United States v. Biggins, 
    551 F.2d 64
     (5th Cir. 1977),” which is
    similar to the test established in Baca. 198 Colo. at 163, 
    597 P.2d at 562
    . But, in a portion of Biggins not quoted by the supreme
    court in Alonzi (and not noted by the Baca division), the Fifth
    Circuit also stated, “[i]f the trial judge independently determines
    ———————————————————————
    4 As we read Baca, for purposes of its first alternate authentication
    method, the identification of a voice alone is insufficient to
    authenticate a recording.
    8
    that the recording accurately reproduces the auditory evidence,
    however, his discretion to admit the evidence is not to be sacrificed
    to a formalistic adherence to the standard we establish.” 
    551 F.2d at 67
    .
    ¶ 18   Moreover, there is a real question whether the portion of Alonzi
    relied on by the Baca division was dictum. As stated by the
    supreme court, the precise question presented in Alonzi was
    whether the proponent of an audio recording was required to prove
    a chain of custody. Alonzi, 198 Colo. at 163, 
    597 P.2d at 562
    . The
    supreme court held that a chain of custody was not always
    required. 
    Id.
     Having definitively answered the question raised by
    the appellant, the court nevertheless addressed other matters not
    necessary to its decision. 
    Id.
    ¶ 19   Even if the supreme court’s statements in Alonzi regarding the
    required methods to authenticate an electronic recording constitute
    a holding of the court, and not dictum, the source of authority for
    both Alonzi and the Colorado Rules of Evidence is the same — the
    Colorado Supreme Court. See Colo. Const. art. VI, § 21; Forma Sci.,
    Inc. v. BioSera, Inc., 
    960 P.2d 108
    , 116 (Colo. 1998) (“The Colorado
    Rules of Evidence were adopted under this court’s rule-making
    9
    powers articulated in the Colorado Constitution.”). When the
    Colorado Supreme Court exercises its constitutional authority and
    adopts a rule of procedure or evidence that conflicts with an earlier
    opinion of that court, the later precedent or rule controls, not the
    former. See Ramirez, 155 P.3d at 374-75.
    ¶ 20   Neither the language of CRE 901 nor its underlying purpose
    supports the prescription of two exclusive methods to authenticate
    a voice recording. As noted above, CRE 901 does not set forth any
    categorical or exclusive rules. To the contrary, the very structure of
    CRE 901 eschews such categorical rules. As a division of this court
    stated in Glover, ¶ 25 (quoting Tienda v. State, 
    358 S.W.3d 633
    , 639
    (Tex. Crim. App. 2012)), in the context of authenticating records
    from Facebook or another social networking website, “jurisdictions
    across the country have recognized that electronic evidence may be
    authenticated in a number of different ways consistent with Federal
    Rule 901 and its various state analogs.”
    ¶ 21   We agree that CRE 901 contemplates a flexible, factual inquiry
    to determine under the facts of each case whether a reasonable jury
    could determine that the proffered evidence “is what its proponent
    claims.” Glover, ¶ 12. In making this determination, the trial court
    10
    necessarily has broad discretion to consider a variety of factors and
    circumstances.
    ¶ 22   In some cases, under some circumstances, particularly when
    there is a colorable claim that a recording has been altered, the
    factors discussed in Baca may be highly pertinent to the
    authenticity determination. In other cases, the factors identified by
    Baca may be inapplicable or unnecessary.
    ¶ 23   The deficiencies of such a categorical rule are illustrated by
    the facts in State v. Smith, 
    540 P.2d 424
     (Wash. 1975). In that
    murder case, the victim took the precaution of carrying a tape
    recorder with him while keeping an appointment with the murderer.
    Id. at 426. During the victim’s autopsy, the authorities found the
    tape recording. Id. Despite the fact that the recording did not
    satisfy categorical common law rules for authentication similar to
    those adopted in Baca, the Washington Supreme Court held that
    the recording was admissible on the basis of scientific testimony
    and other evidence corroborating its accuracy and completeness.
    Id. at 429.
    ¶ 24   Or, take the hypothetical situation where a serial killer keeps
    an oral diary of his activities. After the killer’s arrest, the police find
    11
    the oral diary in his residence. No recording equipment is found in
    the house. A police detective who has interviewed the killer testifies
    that the voice on the tape is that of the defendant. As we read
    Baca, the diary would be inadmissible even though, under the
    circumstances, the recording would be highly probative and reliable
    evidence of the crimes.
    ¶ 25   Other courts, applying their versions of Fed. R. Evid. 901,
    have rejected the common law standards typified by Alonzi, Biggins,
    and Baca in favor of a more flexible approach.5 For example, the
    Michigan Supreme Court concluded that Michigan’s adoption of
    Fed. R. Evid. 901 abrogated the more specific common law
    reliability of recording process factors, in favor of a more flexible
    approach. People v. Berkey, 
    467 N.W.2d 6
    , 10-12 (Mich. 1991); see
    also Angleton v. State, 
    971 S.W.2d 65
    , 68-69 (Tex. Crim. App. 1998)
    (en banc) (same, applying Texas equivalent of CRE 901); State v.
    ———————————————————————
    5 When the Colorado Supreme Court adopted the Colorado Rules of
    Evidence, CRE 901 was substantively identical to Fed. R. Evid. 901.
    Thus, interpretations of Fed. R. Evid. 901 are highly persuasive in
    our interpretation of CRE 901. See People v. Short, 
    2018 COA 47
    ,
    ¶ 41. In 2011, many of the Federal Rules of Evidence were
    rewritten in more contemporary language, but no substantive
    changes were intended. Fed. R. Evid. 901 advisory committee’s
    note to 2011 amendments.
    12
    Jackson, 
    54 P.3d 739
    , 742-43 (Wash. Ct. App. 2002)
    (acknowledging reliability of recording process factors but holding
    that those factors are not the exclusive determinants of
    authenticity).
    ¶ 26   As the Eighth Circuit has observed, “[p]rivate use of recording
    equipment has become widespread,” and therefore specific factors
    relating to the reliability of the recording process “should be applied
    in a practical light to assure the reliability of the recorded material,”
    rather than in a “mechanical or wooden” manner. United States v.
    O’Connell, 
    841 F.2d 1408
    , 1420 (8th Cir. 1988). The same court
    noted that recordings discovered by the police should not “be
    subject to the same requirements [that courts] apply when a
    government agent or informant initiates a conversation knowing
    that it is to be recorded.” Id.; see also Angleton, 
    971 S.W.2d at 68
    (“[T]he government does not have to prove when, where, how, and
    by whom tape recordings were made, when those recordings were
    recovered from the defendant or an alleged co-defendant, were not
    created as a result of government involvement, were not tampered
    with, and the defendant is identified as a speaker on the tape.”).
    13
    ¶ 27   Similarly, authoritative treatises addressing Fed. R. Evid. 901
    have recognized that the rule establishes flexible procedures for
    determining the authenticity of an electronic recording. See, e.g., 8
    Michael H. Graham, Handbook of Federal Evidence § 901:5,
    Westlaw (8th ed. database updated Nov. 2018) (“The specific
    requirements for authentication of sound recordings vary depending
    upon the circumstances.”); 5 Christopher B. Mueller & Laird C.
    Kirkpatrick, Federal Evidence § 9:14, Westlaw (4th ed. database
    updated July 2018) (“[M]ost courts refuse to be pinned down to the
    [common law] approach and favor greater flexibility in assessing
    authenticity of recorded evidence.”); 31 Charles A. Wright & Victor
    J. Gold, Federal Practice and Procedure § 7110, Westlaw (1st ed.
    database updated Nov. 2018) (“[I]n the case of telephone
    communications the trier of fact undoubtedly is familiar with the
    device and well aware of the potential for problems, thus alleviating
    the need for a detailed foundation.”). 6
    ———————————————————————
    6 2 Kenneth S. Broun, McCormick on Evidence § 216 n.29, Westlaw
    (7th ed. database updated June 2016), describes strict rules similar
    to the ones adopted in Baca, but then refers to People v. Sangster, 
    8 N.E.3d 1116
     (Ill. App. Ct. 2014) “[f]or an example of a more relaxed
    foundation.” McCormick then contrasts the approach in Sangster
    with the approach in People v. Baca, 
    2015 COA 153
    .
    14
    ¶ 28   The Alonzi court was legitimately concerned about falsification
    of electronic recordings. See Alonzi, 198 Colo. at 163-64, 
    597 P.2d at 562
    . There is no question that the alteration of electronic
    recordings, whether audio or video, is more of a risk today than
    when Alonzi was decided in 1979. See Bruce E. Koenig & Douglas
    S. Lacey, Forensic Authentication of Digital Audio and Video Files, in
    Handbook of Digital Forensics of Multimedia Data and Devices 133
    (Anthony T. S. Ho & Shujun Li eds., 2015).
    ¶ 29   Developments in computer technology and software enable
    almost any owner of a personal computer with the necessary
    knowledge and software to falsely edit recordings. 
    Id.
     But, the fact
    that the falsification of electronic recordings is always possible does
    not, in our view, justify restrictive rules of authentication that must
    be applied in every case when there is no colorable claim of
    alteration. See People v. Sangster, 
    8 N.E.3d 1116
    , 1127 (Ill. App.
    Ct. 2014) (“[N]either at trial nor before [the appellate court] did
    Sangster make a colorable claim that the recording was other than
    authentic or accurate.”).
    15
    ¶ 30   Thus, the trial court must consider all relevant circumstances
    that bear on whether a recording is what it purports to be. 7 When a
    plausible claim of falsification is made by a party opposing the
    introduction of a recording, the court may and usually should apply
    additional scrutiny (including, when appropriate, the Baca factors)
    to make the preliminary determination entrusted to the trial court:
    Could a reasonable jury determine that the thing offered into
    evidence is what it purports to be?
    2.    Application
    ¶ 31   Applying this flexible approach of CRE 901 to the voicemail in
    this case, we conclude that the trial court properly made a
    preliminary finding that it was what it purported to be. There was
    no claim by Gonzales that the recording was falsified or
    manipulated in any way. The recording was found in the decedent’s
    house by his sister after the premises were released to her by the
    police. A police officer who interrogated Gonzales at length testified
    that Gonzales’s voice was heard on the voicemail. These
    uncontested facts were sufficient to support a CRE 901 finding that
    ———————————————————————
    7 CRE 104 provides that in making preliminary determinations such
    as authenticity, the court is not bound by the rules of evidence.
    16
    the voicemail was what the prosecutor purported it to be — a
    voicemail left by Gonzales for the victim. The ultimate
    determinations of whether the voicemail was authentic and the
    weight, if any, to be given to it were exclusively for the jury to
    determine. See People in Interest of A.C.E-D., 
    2018 COA 157
    , ¶ 43;
    Glover, ¶ 13.
    ¶ 32   Accordingly, the trial court did not abuse its discretion in
    admitting the voicemail.
    III.   The Trial Court Correctly Admitted the Photograph of
    Gonzales’s Tattoos
    ¶ 33   In his only other contention of error, Gonzales argues that the
    trial court abused its discretion in admitting a photograph showing
    Gonzales’s tattoos because it was both irrelevant and highly
    prejudicial. We disagree on both fronts.
    ¶ 34   All relevant evidence is admissible unless prohibited by
    constitution, statute, or court rule. CRE 402; Kaufman v. People,
    
    202 P.3d 542
    , 552 (Colo. 2009). Evidence is relevant if it makes the
    existence of any fact of consequence more or less probable. CRE
    401. But, even relevant evidence may be excluded “if its probative
    value is substantially outweighed by the danger of unfair prejudice.”
    17
    CRE 403. Evidence is unfairly prejudicial if it has “some undue
    tendency to suggest a decision on an improper basis, commonly an
    emotional basis, such as bias, sympathy, hatred, contempt,
    retribution, or horror.” People v. Cardenas, 
    2014 COA 35
    , ¶ 52
    (quoting People v. Fasy, 
    813 P.2d 797
    , 800 (Colo. App. 1991)).
    ¶ 35   The photograph at issue shows Gonzales shirtless with two
    tattoos on his inner forearms clearly visible. The tattoo on one arm
    says “CHUBBY,” and the tattoo on the other says “CHASER.” No
    other tattoos are visible in the photograph.
    ¶ 36   “Evidence of a defendant’s tattoos may be relevant to that
    defendant’s intent and motive.” Id. at ¶ 51. The photograph was
    relevant to prove Gonzales’s motive. Gonzales said during his police
    interview that he was attracted to heavyset men. The photograph
    corroborates that statement and supports the prosecution’s theory
    that Gonzales targeted the victim because his body type was
    consistent with Gonzales’s preferred body type.
    ¶ 37   Gonzales argues that the photograph was highly prejudicial
    because from it the jury could have inferred that Gonzales chased
    chubby men with the intention of doing them harm, rather than
    because he was sexually attracted to them. But once relevance is
    18
    established, the inferences drawn from that evidence are solely for
    the jury to draw, not an appellate court. See People v. Summit, 
    132 P.3d 320
    , 324 (Colo. 2006). Under CRE 403, an appellate court
    assumes the maximum probative value of relevant evidence and the
    minimum prejudicial value. People v. Gibbens, 
    905 P.2d 604
    , 607
    (Colo. 1995). Applying that rule here, the trial court acted well
    within its discretion in admitting the photograph. Gonzales
    admitted both that he was he was attracted to larger men and that
    he killed a person who fit that physical description. On these facts,
    the jury was entitled to consider the probative value of the tattoos. 8
    IV.   Conclusion
    ¶ 38   The judgment of conviction is affirmed.
    JUDGE TOW concurs.
    JUDGE TAUBMAN specially concurs.

    8 Gonzales also claims that it was unnecessary for the jury to see
    his bare torso. But Gonzales does not explain, and we cannot
    discern, how the image of his bare torso might incite such “bias,
    sympathy, hatred, contempt, retribution, or horror” that it would
    render the admission of this evidence improper or prejudicial.

    2014 COA 35

    JUDGE TAUBMAN, specially concurring.
    ¶ 39   Although the majority declines to follow People v. Baca, 
    2015 COA 153
    , 
    378 P.3d 780
    , “to the extent Baca purports to establish
    an exclusive rule for the authentication of a voice recording,” I do
    not share that interpretation. Supra ¶ 2. As a member of the Baca
    division, I agreed with its analysis, and I still do. I also agree with
    much of the majority’s analysis in this case and its conclusion that
    the microcassette recording that appeared to have the voice of
    defendant, Daniel J. Gonzales, was properly admitted.
    ¶ 40   While some language in Baca suggests that the division
    intended to establish an exclusive rule for the authentication of
    voice recordings, the Baca division acknowledged that CRE 901(a)
    sets forth a broad standard for the authentication of evidence,
    including voice recordings. In Baca, the division held that to
    authenticate a voice recording, a witness had to show independent
    knowledge of the content of a telephone call or an ability to verify
    the accuracy of the recording process. That test was especially
    appropriate under the facts in that case, which involved the
    admissibility of a telephone conversation between a jail inmate and
    his mother. In those circumstances, undoubtedly, many inmates
    20
    made telephone calls, thereby making it necessary to ensure the
    identity of the callers to authenticate the phone conversation.
    ¶ 41   Here, in contrast, the court was concerned with the
    admissibility of a microcassette recording found by the victim’s
    sister in the victim’s home. In that situation, there was a reduced
    likelihood of improper authentication of Gonzales’s voice.
    ¶ 42   Accordingly, because I agree that the results in both Baca and
    this case were correct, I specially concur.
