    TAWANDA SHEFFIELD, STEVEN D. LEWIS, and ALLEN BUTLER, APPELLANTS,
    v.
    UNITED STATES, APPELLEE.
    Appeals from the Superior Court
    of the District of Columbia
    (CF1-24022-09, CF1-18224-09, & CF1-28939-08)
    (Hon. William M. Jackson, Trial Judge)
    (Argued June 5, 2014                                     Decided March 12, 2015)
    Michael L. Spekter for appellant Tawanda Sheffield.
    Sydney J. Hoffmann for appellant Steven D. Lewis.
    Thomas T. Heslep for appellant Allen Butler.
    David P. Saybolt, Assistant United States Attorney, with whom Ronald C.
    Machen Jr., United States Attorney, and Elizabeth Trosman, Elizabeth H. Danello,
    and Kevin Flynn, Assistant United States Attorneys, were on the brief, for appellee.
    Before WASHINGTON, Chief Judge, THOMPSON, Associate Judge, and
    NEBEKER, Senior Judge.
    NEBEKER, Senior Judge: In this consolidated appeal, appellants Allen Butler
    and Steven D. Lewis appeal from their convictions for the lesser-included offense
    2
    of second-degree murder while armed (D.C. Code § 22-2403, -4502) and various
    accompanying weapon convictions. Appellant Tawanda Sheffield also appeals her
    convictions for two counts of obstruction of justice (D.C. Code § 22-722 (a)(6))
    and one count of perjury (D.C. Code § 22-2402 (a)(1)). Appellants raise ten issues
    on appeal, asserting violations of their Fourth Amendment rights, Miranda rights,
    and confrontation rights, and also asserting, among other claims, Brady violations,
    improper rebuttal testimony, a prejudicial jury demonstration, and insufficient
    evidence to support the various convictions. We have limited our consideration to
    the stronger issues presented, and any arguments not directly addressed are deemed
    to not warrant such treatment, especially not reversal of any convictions on this
    record on appeal. For the reasons stated below, we affirm in part and remand for
    vacatur of one of Sheffield’s obstruction of justice convictions and adjustment of
    Sheffield’s sentence as may be necessary.
    I. Factual Overview
    A. The Murder and Bloody Pants Evidence
    On December 11, 2008, around 8:00 a.m., in the District of Columbia,
    Butler and Lewis forcefully entered the home of Franklin Johnson, a known drug
    3
    dealer, in an attempted robbery.    The home, a short drive away from Prince
    George’s County Hospital, was occupied by Johnson; the sister of Johnson’s
    girlfriend, Donna Galloway; Johnson’s one-year-old child; and two other children,
    J.B. (age five), and L.B. (age six).    Butler and Lewis, wearing black masks
    covering all but their eyes, forced their way into the home. Once inside, the men
    began shooting, killing Johnson and wounding J.B. Butler was also shot in his leg
    during the encounter. Forensic analysis revealed that Johnson was shot ten times
    at close range, and the bullets recovered were consistent with having been fired by
    two guns. Butler and Lewis fled the scene in a burgundy mini-van with Georgia
    tags.
    At 8:37 a.m., Butler was admitted to Prince George’s County Hospital for
    treatment of a gunshot wound to his leg. During the course of treatment, the
    Hospital staff removed his pants and placed them in a hospital biohazard bag by
    Butler’s bed. Pursuant to Maryland law, see Md. Code Ann., Health–Gen.
    § 20-703, the Hospital staff contacted the Prince George’s County Police
    Department (PGPD) to report the “walk-in shooting victim” and two PGPD
    detectives responded to the Hospital to investigate the shooting.      During the
    investigation, Butler presented different accounts of how he had been shot, first
    claiming to be a victim of a robbery and then that he had been shot by his friend’s
    4
    boyfriend. As a result, the investigation was transferred back and forth between
    the first PGPD detectives to respond and the PGPD robbery suppression team.
    PGPD investigators ultimately asked Butler to join them in canvassing the
    area of the alleged crime. While Butler was in the process of being discharged,
    PGPD Detective Gurry retrieved the bag of clothes by Butler’s bed, walked to the
    car, and placed the bag in the trunk of the car. Detective Gurry then drove to the
    entrance of the Hospital and Detective Pettus came out pushing Butler in a
    wheelchair. Although Butler claims that he twice asked for his clothes back, the
    trial court did not credit this testimony.1 For over one and one-half hours the
    detectives canvassed the area of Butler’s alleged encounter, but Butler was not able
    to direct the detectives to the scene of the alleged shooting. Finally, the detectives
    drove Butler to the PGPD District III station, where he was picked up by
    Lavangela Smith, the woman who had rented the burgundy mini-van used in the
    get-away and with whom Butler lived and had an intimate relationship. PGPD
    detectives logged Butler’s clothes into PGPD property, where they remained until
    the following day when they were released to the homicide detectives from the
    Metropolitan Police Department (MPD) who were investigating the D.C.
    1
    The trial court’s finding regarding Butler’s testimony is important to our
    discussion, infra, of the detectives’ lawful access to Butler’s clothing with regard
    to the plain view doctrine.

    murder. On December 14, 2008, Butler was arrested, pursuant to a warrant, in
    connection with the murder of Johnson. Later, in 2009, DNA testing of Butler’s
    pants revealed the presence of Butler’s blood and Johnson’s blood. On February
    12, 2009, Lewis was also arrested.
    B. Obstruction of Justice and Perjury Convictions
    There was evidence that Butler had asked appellant Sheffield to provide an
    alibi. On December 11, at 12:45 a.m. there were two calls between Butler and
    Sheffield. Then, at 4:38 p.m. Sheffield texted appellant Butler’s cousin, Tarik
    Butler, “I guess use me but its ok I’m a soldier.” Later that night there was a third
    call between appellant Butler and Sheffield.         Additionally, Damon White, a
    government jail house informant, testified that Butler told him that he had spoken
    with two sisters, appellant Sheffield and Keisha Sheffield, who were going to
    testify before the grand jury on his behalf. Keisha Sheffield later testified before
    the grand jury that Butler had asked her and her sister to provide an alibi by
    testifying that they all were at a club together at the time of the murder.
    On December 13, 2008, MPD detectives contacted appellant Sheffield and
    asked her to come to their headquarters for an interview. Sheffield voluntarily
    6
    provided a videotaped statement in which she asserted that the night before the
    murder she had driven Butler to her home in Riverdale, Maryland around 11:45
    p.m., and that Butler had remained with her until he left the next morning, around
    9:30 a.m. On October 15, 2009, Sheffield repeated this assertion before a grand
    jury, maintaining this account despite being presented with evidence establishing
    that at 8:37 a.m. on December 11, 2008, Butler was at Prince George’s County
    Hospital being treated for his gunshot wound.
    C. Brady Disclosures and Young Rebuttal
    At trial Butler introduced a stipulation explaining that on December 11,
    2008, six-year-old L.B.—an eyewitness to Johnson’s shooting—told police that he
    recognized one of the assailants as “Gangsta,” whom he had previously seen with
    the decedent in the Parkwood area, but that this information was not disclosed to
    the defense until April 8, 2011. The stipulation also stated that L.B.’s description
    of Gangsta was disclosed on April 21, 2011, and that L.B.’s videotaped statement
    was disclosed on April 28, 2011. On June 3, 2011, after trial had begun, the
    government notified the defense that police had discovered a man named Gary
    Young, Jr., who went by the nickname “Gangsta” and was an associate of Johnson
    at the time of his death. The government called Young and, with the court’s
    7
    permission, asked him to put on the black ski mask recovered from Lewis and
    stand next to a redacted photo of Lewis wearing the black mask, to show that the
    two men looked similar and that L.B. could easily have confused one man for the
    other.
    II. Analysis
    A. Butler’s Motion to Suppress the Clothing, the DNA Results, and His
    Statements to Police
    Butler argues that we should vacate his conviction for the lesser-included
    offense of second-degree murder while armed2 and various accompanying weapon
    convictions because the trial court erred by failing to suppress (1) his seized
    clothing, (2) the forensic test results showing Johnson’s blood on his pants, and (3)
    his statements to police. The trial court concluded that the “seizure [fell] within
    the meaning of the Fourth Amendment,” but that it was reasonable under the plain
    view exception to the warrant requirement or, alternatively, that Butler consented
    2
    We find no merit to Butler’s argument that it was error to instruct the jury
    on second-degree murder as a lesser-included offense of felony murder while
    armed because the jury could reasonably acquit Butler of felony murder by finding
    that he did not commit the underlying burglary felony, which is consistent with
    Butler’s defense theory that he was at Johnson’s home simply to buy drugs. There
    was sufficient evidence from which the jury could find that Butler formed the
    intent to kill on impulse while in Johnson’s home.
    8
    to the search by falsely claiming to be a gunshot victim. Additionally, the trial
    court held that once the police lawfully had the pants in their possession, they had
    a right to transfer the pants to D.C. police and conduct forensic testing without a
    warrant. Finally, the trial court found that Butler’s statements were a “voluntary”
    and “intelligent waiver of his Miranda rights” because Butler had “initiated
    statements to the officers and [ ] was not prompted in any way.”
    Our review of “a trial court’s ruling on a motion to suppress tangible
    evidence requires that the facts and all reasonable inferences therefrom must be
    viewed in favor of sustaining the trial court’s ruling.” Holt v. United States, 
    675 A.2d 474
    , 478 (D.C. 1996) (internal citation and quotation marks omitted). The
    trial court’s determination of probable cause is a conclusion of law that we review
    de novo. Prince v. United States, 
    825 A.2d 928
    , 931 (D.C. 2003). We review the
    trial court’s finding that Butler initiated discussion with police for clear error.
    See Morris v. United States, 
    728 A.2d 1210
    , 1219 (D.C. 1999).
    1. The Seizure of Butler’s Clothing
    The facts surrounding this issue present two ways of resolving it. One is that
    the Fourth Amendment is not implicated due to the fact that the PGPD viewed
    9
    Butler not as a criminal suspect, but a victim of a shooting. If the Amendment is
    not implicated, there is no occasion to deal with the Amendment’s requirement that
    a warrant based on probable cause was necessary. The other way to resolve the
    issue is to hold or assume that the Amendment is implicated, and that a warrant
    was either required or that an exception to the requirement applies. Either way, the
    result would be the same: the constable did not blunder and the trial judge did not
    err in denying the motion to suppress. To assume that the Amendment is
    implicated leads to a conundrum: what could be the probable cause for a warrant,
    as Butler was not then a criminal suspect for any offense, including a false
    report. Thus, no warrant could issue and the pants remain corroborative evidence
    of the reported robbery and assault. It is unnecessary even to consider, as the trial
    judge did, that Butler’s report amounted to a waiver because the elements of a
    waiver are not present. Nor, as we will see, would a warrant be necessary when
    the PGPD transferred the pants to MPD.
    Assuming that the Fourth Amendment did apply, the trial court did not err in
    admitting the evidence. In 
    Holt, supra
    , we upheld investigators’ initial search of
    the appellant’s clothing in a public hospital and the subsequent seizure of the
    clothing incident to his lawful arrest. 675 A.2d at479-81. Just as in this case, the
    appellant in Holt was voluntarily admitted to a public hospital with a gunshot
    10
    wound, during treatment his clothing was removed and placed in a bag in his room,
    and there was no indication that he asked to secure his clothes in a locker. 
    Id. at 480.
    The police inspected Holt’s clothing to determine that it was consistent with a
    lookout description call to police, and subsequently seized the clothing incident to
    arrest. 
    Id. at 477-78.
    We held that the search was lawful as the appellant “had no
    reasonable expectation of privacy in the appearance of his publicly worn clothing”
    under the circumstances. 
    Id. at 480-81
    (quoting Katz v. United States, 
    389 U.S. 347
    , 361 (1967) (alteration in original) (“‘[W]hat a person knowingly exposes to
    the public . . . is not a subject of Fourth Amendment protection’ because the
    exposure withdraws any expectation of privacy.”)). Other courts have upheld
    similar searches, finding that there is no reasonable expectation of privacy in
    personal effects in an emergency room. See, e.g., People v. Sutherland, 
    415 N.E.2d 1267
    , 1271 (Ill. App. Ct. 1980); State v. Smith, 
    559 P.2d 970
    , 976 (Wash.
    1977) (en banc); Wagner v. Hedrick, 
    383 S.E.2d 286
    , 291-92 (W. Va. 1989).
    The reasoning in Holt alone, however, will not suffice to uphold the officers’
    collection of Butler’s clothing in this case because the Fourth Amendment protects
    against unreasonable seizures of property in which the individual has a possessory
    interest, even if a privacy or liberty interest is not at issue. For the purposes of the
    Fourth Amendment, a “‘seizure’ of property occurs when there is some meaningful
    11
    interference with an individual’s possessory interests in that property.” United
    States v. Jacobsen, 
    466 U.S. 109
    , 113 (1984). Although we have previously held
    that a party seeking to suppress evidence unlawfully seized “must first prove that
    he had a legitimate expectation of privacy in . . . the item seized,” In re B.K.C., 
    413 A.2d 894
    , 899 (D.C. 1980), subsequent United States Supreme Court decisions
    have contrarily held that the Fourth Amendment protects against unreasonable
    seizures of property even when a privacy or liberty interest is not at issue, see, e.g.,
    United States v. Jones, 
    132 S. Ct. 945
    , 952 (2012) (“[T]he Katz reasonable-
    expectation-of-privacy test has been added to, not substituted for, the common-law
    trespassory test.”); United States v. Flores-Montano, 
    541 U.S. 149
    , 154-55 (2004);
    United States v. Padilla, 
    508 U.S. 77
    , 80-81 (1993); Soldal v. Cook Cnty., Ill.,
    
    506 U.S. 56
    , 65-66 (1992).
    In 
    Soldal, supra
    , the Supreme Court noted that none “of the Court’s prior
    cases supports the view that the Fourth Amendment protects against unreasonable
    seizures of property only where privacy or liberty is also implicated,” explaining
    that “the absence of a privacy interest notwithstanding, ‘[a] seizure of the article
    . . . would obviously invade the owner’s possessory 
    interest.’” 506 U.S. at 65-66
    (alterations in original) (quoting Horton v. California, 
    496 U.S. 128
    , 134 (1990));
    see also 
    Flores-Montano, supra
    , 541 U.S. at 154 (“[T]he Fourth Amendment
    12
    ‘protects property as well as privacy.’”) (quoting 
    Soldal, supra
    , 506 U.S. at 62);
    United States v. Jones, 
    625 F.3d 766
    , 770 (D.C. Cir. 2010) (same); United States v.
    Davis, 
    657 F. Supp. 2d 630
    , 636 (D. Md. 2009) (“[T]o challenge a seizure, a
    defendant need only establish that the seizure interfered with his constitutionally
    protected possessory interests. The infringement of privacy rights, while often a
    precursor to a seizure of property, is not necessary to such challenge.”), aff’d, 
    690 F.3d 226
    (4th Cir. 2012); Jones v. State, 
    648 So. 2d 669
    , 675 (Fla. 1994) ( “[E]ven
    if we were to find that Jones’[s] privacy interests were in no way compromised,
    there clearly was a meaningful interference with his constitutionally protected
    possessory rights when his effects were seized without a warrant.”); People v.
    Hayes, 
    584 N.Y.S.2d 1001
    , 1002 (N.Y. Sup. Ct. 1992) (concluding that the
    defendant’s property rights were violated when his belongings were removed from
    a hospital without a warrant). Therefore, despite our holding in Holt that an
    individual entering a public hospital with a gunshot wound has no reasonable
    expectation of privacy in their appearance, we recognize Butler’s separate
    possessory interest in his clothes and address for the first time whether under these
    circumstances a seizure of such property violates the Fourth Amendment.
    It is undisputed that Butler’s clothing was removed from his hospital room
    without a warrant. Warrantless seizures are “subject to only a few specifically
    13
    established and well-delineated exceptions.”3 
    Katz, supra
    , 389 U.S. at 357; see
    also, e.g., Martin v. United States, 
    952 A.2d 181
    , 186 (D.C. 2008). However, the
    “plain view” exception to the warrant requirement “permits law enforcement to
    seize objects if (1) the officer is lawfully present in the location where the
    observation is made[;] (2) the officer has lawful access to the item[;] and
    (3) the object’s incriminating nature is immediately apparent,” 
    Davis, supra
    ,
    657 F. Supp. 2d at 637; see also 
    Horton, supra
    , 496 U.S. at 136-37;
    Porter v. United States, 
    37 A.3d 251
    , 256-57 (D.C. 2012), or it is clear to the law
    enforcement officer that the object is or contains evidence of a crime, United States
    v. Pindell, 
    336 F.3d 1049
    , 1055 (D.C. Cir. 2003). The discovery of evidence in
    plain view need not be inadvertent. 
    Horton, supra
    , 496 U.S. at 130. In the instant
    case, these plain view criteria are satisfied, even though the incriminating nature of
    the bloody pants was not as immediately apparent as their evidentiary value in
    relation to Butler’s original claim that he was a victim.
    First, the police were lawfully in Butler’s hospital room on official business
    to investigate a reported shooting because they were contacted by the hospital staff
    to report the “walk-in shooting victim” and later returned to investigate the crime
    3
    The trial court relied on a theory of plain view and alternatively implied
    consent to justify the seizure. We affirm without relying on the ground of consent.
    14
    reported by Butler. Second, the officers had lawful access to Butler’s clothing
    because, as we held in 
    Holt, supra
    , there is no expectation of privacy in clothing in
    a public hospital where one’s appearance upon arrival is 
    public. 675 A.2d at 48
    .
    The officers, therefore, did not invade Butler’s privacy interest by noting Butler’s
    bloody clothes in the biohazard bag by his bed.
    Finally, the importance of Butler’s clothing was immediately apparent
    because the officers had “probable cause to believe that [it] contained evidence of a
    crime.” 
    Pindell, supra
    , 336 F.3d at 1055. “[W]hen a container is not closed, or
    transparent, or when its distinctive configuration proclaims its contents, the
    container supports no reasonable expectation of privacy and the contents can be
    said to be in plain view.” 
    Davis, supra
    , 657 F. Supp. 2d at 638 (internal citation
    and quotation marks omitted). Additionally, “[t]he circumstances under which an
    officer finds the container may add to the apparent nature of its contents.” 
    Id. Detective Gurry
    testified that he regularly responded to gunshot wound calls at
    hospitals and that it was standard practice to ask for the hospital bag containing the
    victim’s property. The detectives knew that Butler had a gunshot wound in his leg,
    an area of the body that is usually covered by clothing, and that he was claiming to
    be the victim of a shooting. They photographed Butler’s bleeding wound, saw the
    red biohazard bag containing his bloody clothing by his bed, and were told by the
    15
    nurse and Butler that the bag contained Butler’s clothes. It was readily apparent
    that the bloody clothes were evidence of a crime, regardless of whether Butler was
    a victim or a suspect. We conclude, therefore, that if Butler’s pants were seized
    while he was a patient at Prince George’s County Hospital, the seizure was lawful
    pursuant to the plain view exception to the warrant requirement.4
    2. The Search Yielding Johnson’s DNA
    The extraction of blood from Butler’s clothing and the subsequent forensic
    testing of the blood are both searches subject to scrutiny under the Fourth
    Amendment.      The Supreme Court has held in several instances that “the
    government’s use of scientific technology to reveal information that is not visible
    to the naked eye or routinely exposed to the public constitutes a search.”
    See 
    Davis, supra
    , 657 F. Supp. 2d at 644 (listing the Court’s technology cases).
    4
    Because the assumed seizure was lawful, there is no merit to Butler’s
    assertion that transfer of his clothes from PGPD to MPD violated his Fourth
    Amendment rights. To hold otherwise would nonsensically submit lawfully
    obtained evidence to redundant Fourth Amendment assessments at each point of
    transfer between governmental units. As the Ninth Circuit has explained, a
    warrant requirement for transfers would cause “complex procedural barriers to
    cooperation between state and federal law enforcement authorities” and is
    unnecessary because “examination by another law enforcement agency is not a
    sufficiently distinct intrusion into the defendants’ privacy to trigger the
    requirements of the Fourth Amendment.” United States v. Romero, 
    585 F.2d 391
    ,
    396 (9th Cir. 1978).
    16
    However, the Court has held more specifically that “clothing or other belongings
    may be seized upon arrival of the accused at the place of detention and later
    subjected to laboratory analysis,” the results of which are admissible at trial.
    United States v. Edwards, 
    415 U.S. 800
    , 804 (1974).                In upholding the
    reasonableness of these types of searches, the Court explained that “it is difficult to
    perceive what is unreasonable about the police’s examining and holding as
    evidence those personal effects of the accused that they already have in their lawful
    custody.” 
    Id. at 806.
    The D.C. Circuit, in a pre-1971 case binding on this court, see M.A.P.
    v. Ryan, 
    285 A.2d 310
    , 312 (D.C. 1971), similarly affirmed a warrantless search
    and seizure incident to arrest where police seized defendant’s clothing and
    conducted forensic testing of the clothing at the Federal Bureau of Investigation to
    reveal paint chips and other debris from the crime scene, see Robinson v. United
    States, 
    283 F.2d 508
    , 509-10 (D.C. Cir. 1960). The court explained that the search
    and seizure were “proper, since probable cause [of guilt] had already appeared, and
    appellants were validly under arrest.” 
    Id. at 509.
    Although Edwards and Robinson
    were decided in the context of a search and seizure incident to a lawful arrest, the
    same rationale applies with equal force in this case of a plain-view seizure in
    17
    which Butler’s arrest nonetheless preceded the testing of his assumed lawfully
    seized clothes.5
    The additional privacy considerations that usually arise in cases involving
    DNA testing are not present in this case. The blood samples were collected from
    Butler’s lawfully seized pants and therefore did not require any bodily intrusion.
    This distinguishes the case from those in which DNA collection requires “the type
    of ‘severe, though brief, intrusion upon cherished personal security’ that is subject
    to constitutional scrutiny.” Cupp v. Murphy, 
    412 U.S. 291
    , 295 (1973) (quoting
    Terry v. Ohio, 
    392 U.S. 1
    , 24-25 (1968)) (holding that scraping dried blood from
    underneath the suspect’s fingernails constituted such a search).       Additionally,
    while DNA results identifying both Butler and Johnson were admitted into
    evidence, Butler argues that it was the tests yielding DNA from Johnson that were
    the “crucial link in obtaining the conviction.” Having established that Butler’s
    clothing was lawfully seized, it is absurd that Butler would have any legitimate
    expectation of privacy in the decedent’s blood on his pants that would warrant
    suppression of the victim’s DNA at trial. As to Butler’s DNA evidence, as a
    detainee his expectation of privacy “necessarily [is] of a diminished scope” and the
    5
    Butler was arrested pursuant to an arrest warrant three days after PGPD
    seized his clothing and well before any testing of his pants commenced in 2009.
    18
    Supreme Court has upheld the analysis of an arrestee’s DNA as a form of
    identification that is reasonable under the Fourth Amendment. Maryland v. King,
    
    133 S. Ct. 1958
    , 1978 (2013) (quoting Bell v. Wolfish, 
    441 U.S. 520
    , 557 (1979)).6
    Courts most often decide Fourth Amendment questions by a traditional
    method of matching the facts of previously reported decisions with facts of the
    pending case. This is true whether the pending decision favors the defendant or the
    government. Such an approach, like a river course or electricity, is one of taking
    the path of least resistance. While case matching may be helpful in deciding
    reasonableness of police conduct, when we have so many published decisions
    going both ways on similar questions of reasonableness, it seems that judges often
    decide which ones to follow based on subjective, rather than objective,
    reasonableness. But we cannot avoid recognizing that reasonableness is the
    overarching and underlying principle for these decisions. In this opinion we do a
    fair amount of case matching, but on these unique facts (feigning victimhood,
    discovery of its falsity, plain view of the tell-tale pants, and convergence of inter-
    police department investigations) we find nothing unreasonable in the police
    6
    No claim is presented here that the DNA testing went to matters other than
    identification so as to intrude upon Butler’s privacy interest in information about
    medical conditions, hidden traits, or similar information that can be gleaned from
    DNA.
    19
    reaction to any or all of what was done. In sum, the search and assumed seizure of
    Butler’s clothing did not violate his Fourth Amendment rights.
    3. Butler’s Statements to Police
    Butler argues that it was error for the trial court to deny his motion to
    suppress the statements he made to the officers who drove him to be processed at
    the central cellblock, alleging that he was in medical distress and that he should
    have been re-advised of his rights under Miranda v. Arizona, 
    384 U.S. 436
    (1966),
    pursuant to Edwards v. Arizona, 
    451 U.S. 477
    (1981). The prophylactic rule of
    
    Edwards, supra
    , does not apply when “the accused himself initiates further
    communication, exchanges, or conversations with the 
    police.” 451 U.S. at 485
    ; see
    also Rhode Island v. Innis, 
    446 U.S. 291
    , 300-01 (1980) (“[T]he Miranda
    safeguards come into play whenever a person in custody is subjected to either
    express questioning or its functional equivalent”). After considering all of the
    evidence, the trial court found that Butler’s statements were a “voluntary” and
    “intelligent waiver of his Miranda rights” because he was “clearheaded and did not
    appear to be under any type of distress or disoriented,” and that there was no
    coercive conduct or even interrogation by police during the drive. In fact, the court
    found that Butler had “initiated statements to the officers, and [ ] was not prompted
    20
    in any way,” when he told the officer “there were some things he wanted to get off
    his chest.” On the facts found by the trial court, which Butler does not allege were
    clearly erroneous, we find that Butler’s claim lacks merit and we affirm the trial
    court’s denial of the motion to suppress. See Bean v. United States, 
    17 A.3d 635
    ,
    638-39 (D.C. 2011) (“‘[A]ny factual finding anchored in credibility assessments
    derived from personal observations of the witnesses is beyond appellate reversal
    unless those factual findings are clearly erroneous.’”) (quoting Stroman v. United
    States, 
    878 A.2d 1241
    , 1244 (D.C. 2005)).
    B. Butler’s Claim that Dr. Pierre-Louis’s Expert Testimony Violated His
    Confrontation Rights
    Butler claims for the first time on appeal that his confrontation rights were
    violated by the expert testimony of Dr. Pierre-Louis, the District’s Chief Medical
    Examiner, arguing that she did not perform the autopsy herself and some of her
    expert opinions were derived from reading the autopsy report and notes. “When a
    defendant fails to object to the admission of certain testimony, and then further
    develops that testimony on cross-examination, he will not be heard to argue on
    appeal that its admission constituted reversible error.”       Sobin v. District of
    Columbia, 
    494 A.2d 1272
    , 1275 (D.C. 1985). Dr. Pierre-Louis was qualified as an
    expert in the field of forensic pathology and she testified that she had reviewed the
    21
    autopsy file, which was not offered into evidence, and would be offering her own
    independent conclusions. Butler’s counsel stated that he did not object to the
    expert using the autopsy report and drawing her own conclusions and did not raise
    any hearsay objections to particular testimony or confrontation objections. In fact,
    during cross-examination Butler’s counsel elicited the expert’s testimony on the
    number of wounds and bullets recovered from Johnson’s body, evidence of soot
    and stippling indicating shots fired at close range, and he relied on this testimony
    during closing argument.       Butler cannot contest Dr. Pierre-Louis’s expert
    testimony, when he failed to object, further developed it on cross-examination, and
    relied on it during closing arguments. 
    Id. In any
    case, Butler cannot demonstrate
    whether Dr. Pierre-Louis relied on the autopsy report or autopsy photographs, and
    neither this court nor the Supreme Court has decided whether autopsy reports are
    testimonial; Butler therefore cannot show plain error. See Euceda v. United States,
    
    66 A.3d 994
    , 1012 (D.C. 2013).
    C. Butler and Lewis’s Asserted Brady Violations
    Butler and Lewis claim that the trial court abused its discretion by denying
    their motions for mistrial based on two asserted violations of Brady v. Maryland,
    
    373 U.S. 83
    (1963). We reverse a trial court’s denial of motion for mistrial “only
    22
    if it appears irrational, unreasonable, or so extreme that the failure to reverse would
    result in a miscarriage of justice.” Coleman v. United States, 
    779 A.2d 297
    , 302
    (D.C. 2001) (internal citation and quotation marks omitted). Whether an appellant
    has established a Brady violation is a mixed question of fact and law, and we
    therefore review the trial court’s legal conclusions de novo and its findings of fact
    for clear error. Miller v. United States, 
    14 A.3d 1094
    , 1120 (D.C. 2011) (quoting
    United States v. Joseph, 
    996 F.2d 36
    , 39 (3d Cir. 1993)).
    As to the first asserted Brady violation regarding L.B.’s identification of one
    of the shooters as Gangsta, the government concedes that the identification was
    inadvertently not disclosed until about six weeks before trial. Butler and Lewis,
    however, did not move for a continuance and it was not until June 2, 2011—during
    the second week of trial—that they moved for a mistrial on the ground that they
    had searched for Gangsta with no success. The trial court denied the motion,
    finding that the late disclosure could have been remedied by a continuance to
    permit further investigation, and ordered the government to identify the steps it had
    taken to identify Gangsta and further steps it could take.
    The trial court did not abuse its discretion by denying the motion given
    Butler’s and Lewis’s strategic decisions to not request a continuance before trial
    23
    and their failure to establish any resulting prejudice. During its opening statement,
    the government did not make any mention of Gangsta and it told the jury that they
    would not hear from any eyewitness to the murder who could identify the shooters.
    By contrast, Butler’s and Lewis’s opening statements, defense theories, and closing
    arguments made use of the Brady information by refuting the government’s
    assertion that there were no eyewitnesses who could identify the shooters and
    alleging police bias.
    Butler’s and Lewis’s second asserted Brady violation is the mid-trial
    discovery that Gangsta was actually Young. On June 3, 2011, the government told
    Butler and Lewis that their lead detective had discovered (the night before) a man
    named Gary Young, Jr., who went by the nickname Gangsta, was an associate of
    Johnson at the time of his death, and looked similar to the description of Gangsta.
    Butler and Lewis renewed their motions for a mistrial, which the court denied
    because trial counsel were extremely experienced and had chosen not to raise the
    Gangsta issue until trial had started, the available remedies were limited, and
    Young and L.B. were available for interview and to testify. We affirm the trial
    court’s denial of Butler’s and Lewis’s renewed motions for a mistrial because the
    court’s findings are not plainly wrong or without factual support, and furthermore,
    because the government’s immediate disclosure of the information upon discovery
    24
    mid-trial does not constitute the “suppression” required for a Brady violation.
    
    Miller, supra
    , 14 A.3d at 1107 (quoting 
    Brady, supra
    , 373 U.S. at 87).
    D. Lewis’s Claims of Improper Rebuttal Testimony and Prejudicial Jury
    Demonstration
    Lewis claims that the trial court committed plain error by allowing Young’s
    rebuttal testimony and permitting the government to conduct the ski mask
    demonstration for the jury. “Rebuttal evidence refutes, contradicts, impeaches, or
    disproves an adversary’s evidence.” Beynum v. United States, 
    480 A.2d 698
    , 704
    (D.C. 1984). The government called Young in rebuttal to Butler’s and Lewis’s use
    of L.B.’s testimony that the shooter was or looked like Gangsta and L.B.’s
    December 2008 statement that Gangsta was the shooter. Young testified that
    others had used the nickname “Gangsta” to refer to him, but that he was so close to
    Johnson that he could not be the killer, thereby contradicting L.B.’s December
    2008 statement to police and refuting Butler’s and Lewis’s suggestions that Young
    was not Gangsta. The trial court, therefore, did not commit plain error in allowing
    this rebuttal testimony.    Given Lewis’s failure to object, the strong evidence
    against him, and the equivocal nature of both L.B.’s and Young’s testimony, we
    are satisfied that the rebuttal testimony did not prejudice Lewis’s “substantial
    rights” or “seriously affect . . . the fairness, integrity or public reputation” of the
    25
    proceedings. United States v. Olano, 
    507 U.S. 725
    , 732 (1993) (internal citation
    and quotation marks omitted).
    Additionally, during Young’s rebuttal testimony, the court permitted Young
    to conduct a demonstration for the jury over Lewis’s objection. The government
    asked Young to put on a black ski mask recovered from Lewis and stand next to a
    cropped photo depicting Lewis alone, also wearing a mask. We review the trial
    court’s admission of demonstrative evidence for abuse of discretion. See Lloyd v.
    United States, 
    64 A.3d 405
    , 409 (D.C. 2013). “The court may permit the
    introduction or use of a demonstrative aid if it is sufficiently explanatory or
    illustrative of relevant testimony in the case to be of potential help to the trier of
    fact.” 
    Id. (internal citation
    and quotation marks omitted). However, otherwise
    relevant evidence “‘may be excluded if its probative value is substantially
    outweighed by the danger of unfair prejudice.’” Johnson v. United States, 
    683 A.2d 1087
    , 1099 (D.C. 1996) (quoting Fed. R. Evid. 403). Here, the ski mask
    demonstration was illustrative of L.B.’s relevant testimony that the shooter he saw
    in a mask looked like Gangsta. The demonstration was more probative than it was
    prejudicial because it could help the jury determine whether Lewis, around the
    time of the shooting, met L.B.’s description of the shooter as someone who looked
    26
    like Gangsta. The trial court, therefore, did not abuse its discretion by permitting
    the demonstration.
    E. Lewis’s and Sheffield’s Claims of Insufficient Evidence to Support Their
    Convictions
    Both Lewis and Sheffield challenge the sufficiency of the evidence to
    support their convictions. The standard for overturning convictions for evidentiary
    insufficiency is a demanding one, under which “appellants face a difficult burden.”
    Bolden v. United States, 
    835 A.2d 532
    , 534 (D.C. 2003) (per curiam). We “review
    the evidence in the light most favorable to the government, giving full play to the
    right of the jury to determine credibility, weigh the evidence, and draw justifiable
    inferences of fact, and making no distinction between direct and circumstantial
    evidence.” Curry v. United States, 
    520 A.2d 255
    , 263 (D.C. 1987).
    1. Lewis’s Claim of Insufficient Evidence
    Lewis challenges the sufficiency of the evidence to support his convictions
    of second-degree murder while armed, assault with intent to kill while armed, and
    the related weapons offenses, arguing that there was not enough evidence to
    identify him as one of the two shooters. Although no eyewitness identified Lewis
    27
    as the second shooter, the government introduced sufficient evidence from which
    the jury could find him guilty. This evidence includes Lewis’s discussion on the
    day of the murder with his neighbors Kenneth Williams and Lisa Thompson
    regarding a trip “uptown” where his companion had been shot and how he had
    taken the companion to the hospital. Additionally, the burned burgundy van, used
    to get away from the murder, was found near Lewis’s apartment complex. Call
    records also show communications between Butler, Lewis, and Smith on the day of
    the murder, and Smith testified about Butler’s call from Lewis’s cell phone the
    morning of the murder. Furthermore, cell tower location records suggest that
    Butler and Lewis were together in the late-night hours leading up to the murder
    and while fleeing away from the murder along Interstate 295 to Prince George’s
    County Hospital. Finally, White testified that Lewis admitted to him that Lewis
    had been on the scene of the shooting, another person there had left his DNA, and
    Lewis had taken the other person to the hospital. Given this evidence and the
    additional circumstantial evidence presented by the government, the jury had
    sufficient evidence from which to conclude that Lewis was one of the shooters, and
    therefore we find no merit to Lewis’s claim.
    28
    2. Sheffield’s Claim of Insufficient Evidence
    Sheffield contends that there was insufficient evidence to support her perjury
    conviction and the obstruction of justice conviction arising from her grand jury
    testimony. These charges arose from Sheffield’s testimony before the grand jury
    in which she continuously affirmed that she and Butler were in constant company
    from about 12:20 a.m. until 9:30 a.m. on the day of the murder. To prove perjury,
    the government was required to establish that Sheffield “made a false statement of
    material fact under oath with knowledge of its falsity.” Gaffney v. United States,
    
    980 A.2d 1190
    , 1193 (D.C. 2009) (citing D.C. Code § 22-2402). Sheffield claims
    that her statements were not false or made with intent to obstruct the investigation
    because she simply testified that she told investigators that when Butler left that
    morning she looked at her cable box and it said it was 9:30 a.m., without
    commenting on the accuracy of the cable box. However, during the grand jury
    proceedings, she repeatedly affirmed that Butler was with her until 9:30 a.m., at
    times without qualification that this was simply the time on the cable box;
    moreover, she did so despite being confronted with evidence that Butler had
    arrived at Prince George’s County Hospital at 8:37 a.m. and cell phone and cell
    tower evidence that at 9:30 a.m. Butler was in D.C. while she was in Riverdale,
    Maryland. Sheffield’s repeated affirmations that Butler was with her until 9:30
    29
    a.m., when she was aware that he was actually at the Hospital by 8:37 a.m.,
    sufficiently establishes that she testified falsely about a material fact with
    knowledge of the falsity.
    To prove obstruction of justice the government was required to show that
    Sheffield “(1) obstructed or impeded or endeavored to obstruct or impede the due
    administration of justice in an official proceeding, and (2) did so with the intent to
    undermine the integrity of the pending investigation.” Smith v. United States,
    
    68 A.3d 729
    , 742 (D.C. 2013) (citing D.C. Code § 22-722 (a)(6)). “The intent
    required for obstruction of justice often must be inferred from the context and
    nature of the alleged criminal conduct.” 
    Id. (internal citation
    and quotation marks
    omitted).   Sheffield’s consistently false grand jury testimony in the face of
    uncontroverted evidence to the contrary and the prosecutor’s repeated warnings are
    sufficient evidence that she intentionally “endeavored to obstruct or impede the
    due administration of justice” in the proceedings against Butler. However, the
    government concedes that Sheffield’s second obstruction of justice charge, based
    on her statement to police on December 13, 2008, must be vacated because there
    was not yet an “official proceeding,” which is a required element of the crime. For
    this reason, we remand for vacatur of this obstruction of justice conviction and
    adjustment of Sheffield’s sentence as may be necessary.
    30
    Contrary to Sheffield’s claim, her convictions for obstruction of justice and
    perjury do not merge under the test of Blockburger v. United States, 
    284 U.S. 299
    (1932), because perjury, unlike obstruction of justice, does not require proof of an
    official proceeding or intent to undermine the proceeding, but rather a knowing
    false, material statement made under oath, compare D.C. Code 22-722 (a)(6), with
    D.C. Code § 22-2402.       Cf. Riley v. United States, 
    647 A.2d 1165
    , 1168 n.8
    (D.C. 1994) (holding that obstruction of justice and subornation of perjury do not
    merge).   Additionally, the trial court did not commit plain error by joining
    Sheffield’s indictments to those of Butler and Lewis for the underlying crimes
    because her false alibi for Butler constituted the “same series of acts or transactions
    constituting an offense or offenses.” Super. Ct. R. Crim. P. 8 (b); see also, e.g.,
    Sams v. United States, 
    721 A.2d 945
    , 954 (D.C. 1998) (concluding that an
    obstruction of justice count was “logically related” to the underlying substantive
    charges against the appellant’s co-defendants). Nor was it plain error for the court
    to decline to sever Sheffield’s case sua sponte. Sheffield failed to show “‘manifest
    prejudice’” resulting from the joinder of her case with those of her co-defendants
    where there was independent evidence of her guilt, and the jury was properly
    instructed to consider each defendant’s guilt separately and render separate
    verdicts. 
    Sams, supra
    , 721 A.2d at 954 (quoting Elliott v. United States, 
    633 A.2d 27
    , 34-35 (D.C.1993)).
    31
    III. Conclusion
    Accordingly, for the reasons stated above, we affirm in part and remand for
    vacatur of one of Sheffield’s obstruction of justice convictions and adjustment of
    Sheffield’s sentence, as may be necessary.
    So ordered.
