    GLICKMAN, Associate Judge: Gregory Green challenges his convictions for
    armed robbery and felony murder while armed on several grounds. We need
    address only one of them, his claim that the trial court erred in denying his motion
    to suppress evidence the police obtained from his cell phone. Mr. Green argues
    that this evidence was the fruit of an illegal search and seizure arising from the
    presence of law enforcement agents in his home without a search warrant or other
    legal justification. Because we agree that the trial court should have granted the
    motion to suppress the cell phone evidence, and because the erroneous admission
    of that evidence at Mr. Green’s trial was not harmless beyond a reasonable doubt,
    we reverse his convictions.1
    1
    Appellant also argues that the trial court committed other errors entitling
    him to reversal: by using a husher during portions of voir dire in violation of his
    right to a public trial; by failing to grant a mistrial to remedy a Brady violation; by
    instructing the jury inaccurately with respect to aiding and abetting; and by
    imposing consecutive sentences. His argument regarding use of the husher appears
    to be foreclosed by this court’s decision in Blades v. United States, 
    200 A.3d 230
    ,
    241 (D.C. 2019) (holding that “use of the husher during individual-juror voir dire
    did not constitute closure or partial closure of the courtroom, but instead was a
    reasonable alternative to closing the proceeding that protected appellant’s public-
    trial right” (internal citation, quotation marks, and alterations omitted)). And
    because we reverse appellant’s convictions and the other issues are unlikely to
    recur if he is retried, we need not address them. See Broom v. United States, 
    118 A.3d 207
    , 217 n.3 (D.C. 2015).

    I.
    Early on the morning of March 29, 2014, Derrick Williams was shot, killed,
    and robbed in front of his home in Southeast Washington, D.C. Mr. Williams’s
    friend and roommate, Mr. Tillman, heard the shooting, ran to the door, and made
    eye contact with a man who was standing over Mr. Williams’s body and going
    through his pockets to rob him. Mr. Tillman recognized this man as someone he
    knew from the neighborhood by the nickname “Face.” He told the police that
    “Face” was dressed in black and had on a dark hat with white lettering. Mr.
    Tillman also observed that “Face” was accompanied by a man wearing a red Helly
    Hansen jacket. He was uncertain of this second man’s identity but thought it might
    have been somebody known as “Little Charles.”
    A few days later, at around 9:50 a.m. on April 2, 2014, U.S. Marshals
    executed an arrest warrant for appellant, who was believed to be “Face.” The
    Marshals made the arrest at appellant’s home, apparently when he opened the door
    to them, and at some point they entered the residence and removed the other
    4
    persons who were there.2 The Marshals then remained inside appellant’s
    home by themselves. The record does not clarify what the Marshals were doing in
    the home after having cleared the premises, or exactly when they eventually left.
    They did not have a search warrant for appellant’s home.
    After appellant was taken into custody, Metropolitan Police Department
    Detective Travis Barton was called to the scene.       Detective Barton was the
    government’s only witness at the suppression hearing. He testified that one of the
    Marshals involved in appellant’s arrest informed him when he arrived that
    appellant’s cell phone was on a couch in the living room. The Marshal did not tell
    Detective Barton how or when the Marshals discovered the phone in the residence
    or how he knew the phone belonged to appellant.3
    2
    There was no testimony in the trial court proceedings as to exactly where
    at appellant’s home he was arrested, and the motion judge made no finding on the
    point. However, the government’s opposition to appellant’s suppression motion
    represented that appellant was arrested “inside of” his residence when he
    “answered the door,” and the affidavit supporting the post-arrest warrant to search
    appellant’s cell phone similarly stated that the Marshals arrested appellant “when
    he answered the door from inside of” the residence. For present purposes,
    however, the precise location of appellant’s arrest at his home is immaterial.
    3
    The Marshals did not take the phone from appellant when they arrested
    him.
    5
    Detective Barton entered the dwelling. He did not have a search warrant at
    the time. He went in, he testified, to “see if the cell phone was there” and to
    “gather information . . . for the search warrant” by “[t]alk[ing] to the officers inside
    [and] find[ing] out if they had any additional information related to what [the
    police] were doing as far as the search warrant or any visible evidence they saw
    when they were inside the house.” The record does not disclose why the Marshals
    were still in the residence at this time, which was nearly an hour after appellant’s
    arrest, in the absence of a search warrant. Detective Barton testified that the
    Marshals already had finished conducting their protective sweep of appellant’s
    home and had “secured” the location before he entered it.
    Once inside, Detective Barton looked for the cell phone on the living room
    couch and did not find it there. The Marshals did not know what had happened to
    it. To find it, Detective Barton called appellant’s phone number.4 He heard a
    phone ring outside the house. Detective Barton went out and found the phone in
    the hands of appellant’s girlfriend. She identified it as belonging to appellant, and
    the detective then seized it.
    4
    Detective Barton had obtained appellant’s phone number the day before
    the arrest.
    6
    The following day, Detective Barton applied for and obtained a warrant to
    search the cell phone. His affidavit in support of the application stated that the
    phone had been identified as appellant’s by his girlfriend. To identify the phone
    with particularity, the affidavit also included the phone’s unique serial and
    International Mobile Equipment Identity numbers. Detective Barton had obtained
    those numbers by taking off the phone’s back cover and removing its battery.
    The phone’s call log revealed that appellant had received several calls in the
    minutes following Mr. Williams’s murder from a phone number listed under the
    name “Charlie” in the phone’s contact list. The phone also contained photos of
    appellant from a social media account that included the word “face” in its
    username; photos showing appellant wearing a dark baseball cap with white
    lettering; other photos showing him in a red Helly Hansen jacket; and text
    messages between appellant and his child’s mother indicating that appellant did not
    show up for a planned meeting with her on the night of the murder.
    In moving to suppress his cell phone and the evidence obtained from it,
    appellant argued, inter alia, that his Fourth Amendment rights were violated by the
    search of his home without a search warrant after the purpose of the arrest warrant
    had been satisfied, and by the seizure of his phone from his girlfriend “without the
    7
    authorization of any warrant [and without] the justification of any exception to the
    warrant requirement.”      In its opposition, the government argued that exigent
    circumstances justified the warrantless seizure of the phone because it was “in
    imminent danger of destruction or loss.”
    After Detective Barton’s testimony at the suppression hearing revealed that
    the Marshals had concluded their protective sweep before his warrantless entry into
    appellant’s home, appellant argued more specifically that the detective had
    engaged in an unlawful search and that the seizure of his cell phone was the fruit of
    that illegality:
    [O]ne issue that’s presented is that . . . there’s a
    warrantless search when [Detective Barton] enters the
    apartment. The apartment’s been secure[d]. He’s not
    entering for the purpose of securing the apartment. At
    that point, it[] . . . doesn’t fall underneath the Buie[5]
    exception for a protective sweep. The marshals have
    already done that. He enters, whether it was with [or]
    partially [with] the purpose of talking to other officers
    inside or looking for evidence, clearly, what happened
    was he did look for this cell phone . . . . It’s only as a
    result of that . . . entry into that house, that he—it leads
    
    5 Md. v
    . Buie, 
    494 U.S. 325
    (1990). As we discuss below, in Buie the
    Supreme Court held that the Fourth Amendment permits police making a lawful
    in-home arrest to conduct a limited, “cursory” search of the surroundings, on less
    than probable cause and without a search warrant, in order to ensure their safety.
    8
    him, by the officer’s own account, to call that cell phone
    and discover it in the hands of [appellant’s girlfriend].
    Appellant added that Detective Barton’s “concern about what happened with the
    [cell phone]” was the “result of [the] warrantless entry into the home” and that,
    “but for that warrantless entry,” Detective Barton would not have called the phone.
    The judge expressed skepticism that the absence of a search warrant meant the
    police had no right to be on the premises. Appellant answered that “at that point,
    they didn’t have the right to be on the premises” because appellant and all civilians
    had been removed and “the limited purpose of a protective sweep had been
    satisfied.” After having done that, appellant added, the police could secure the
    scene, if they needed to do so, but only “from the outside” of the dwelling.
    In contrast, the government argued that Detective Barton had the right to go
    into the house to confer with the Marshals there in order to prepare a particularized
    and complete application for a search warrant; and that while he was there for that
    lawful purpose, Detective Barton “ha[d] every right to look at things that are in
    plain view and the phone should have been in plain view and it wasn’t.” It then
    was reasonable for the detective to call the phone in order to locate it, and then to
    seize it to prevent the loss or destruction of evidence. The government premised
    9
    this argument on its contention that the Marshals were allowed to remain inside
    appellant’s home to secure it “in anticipation of a search warrant.”
    The judge found that “it seem[ed] as though the intention of law
    enforcement” at the time Detective Barton entered the residence “was to seize the
    scene to make sure that they could locate any evidence that may be connected to
    the offense.” The judge ruled that law enforcement was “certainly in a position to
    do that under the Fourth Amendment.” He further ruled that once Detective
    Barton discovered that appellant’s cell phone was not on the couch, “the exigency
    seem[ed] clear.” Concluding that this exigency—the risk that valuable evidence
    might be lost if the police could not find and recover the cell phone immediately—
    justified the detective’s warrantless seizure of the phone, the judge denied the
    motion to suppress the phone and the evidence obtained from it. The prosecution
    presented and relied on that evidence at trial.
    II.
    Appellant contends that Detective Barton entered his home after the
    justification for any law enforcement presence there without a search warrant was
    over, that the detective did so to collect evidence, and that the trial judge should
    have suppressed the evidence obtained from the search of his cell phone as the fruit
    10
    of the warrantless intrusion.      The government rejoins that the Marshals were
    justified in remaining in the premises to secure it pending the issuance of a search
    warrant, and that the detective therefore could join them for the purposes he did
    without infringing appellant’s Fourth Amendment rights. The sole basis on which
    the government has sought to justify Detective Barton’s entry is the putative
    lawfulness of the Marshals’ presence inside the residence to secure the scene and
    guard any evidence located there.
    When reviewing a trial court’s denial of a motion to suppress evidence, we
    defer to the court’s factual findings unless they are clearly erroneous, but we
    review the court’s legal conclusions de novo.6 For the reasons that follow, we
    agree with appellant that his Fourth Amendment rights were violated.
    The Fourth Amendment prohibits “unreasonable searches and seizures.”7 A
    search occurs within the meaning of the Fourth Amendment when the police
    physically intrude on a constitutionally protected area in order to obtain
    6
    See Hooks v. United States, 
    208 A.3d 741
    , 745 (D.C. 2019) (explaining
    “that our analysis of constitutional questions under the Fourth Amendment is [not]
    constricted” and that our review of the trial court’s conclusions of law is de novo).
    7
    U.S. Const. amend. IV.

    information.8 Because the “physical entry of the home is the chief evil against
    which the wording of the Fourth Amendment is directed,”9 it is a basic principle of
    Fourth Amendment jurisprudence that “searches and seizures inside a home
    without a [search] warrant are presumptively unreasonable”10 unless they come
    within one of “a few specifically established and well-delineated exceptions.”11
    The government bore the burden, therefore, of identifying an exception to the
    warrant requirement that applied here.
    As previously mentioned, the government has relied on only one of those
    few exceptions to justify the Marshals’ and Detective Barton’s entry and
    continuing presence in appellant’s home—the alleged need to impound the
    premises pending execution of a search warrant to prevent unauthorized persons
    from entering and removing or destroying evidence. We address the applicability
    of this exception, but before we do, we think it will be helpful to an understanding
    of the issue we confront to explain briefly why other potentially available
    exceptions did not justify the law enforcement intrusion in this case (and have not

    12
    been relied upon by the government). Those inapplicable exceptions are three in
    number: (1) the authority that may be provided by an arrest warrant; (2) entry to
    conduct a protective sweep of the home for safety purposes; and (3) exigent
    circumstances arising from an imminent threat of removal or destruction of
    evidence in the home.
    First, while the Marshals were armed with a warrant for appellant’s arrest,
    that did not justify their prolonged occupation of appellant’s home, nor Detective
    Barton’s subsequent entry.      “[A]n arrest warrant founded on probable cause
    implicitly carries with it the limited authority to enter a dwelling in which the
    suspect lives when there is reason to believe the suspect is within,” for the purpose
    of making the arrest.12 While officers are effecting a lawful arrest, “search incident
    to arrest” doctrine allows them to search “the area into which an arrestee might
    reach in order to grab a weapon or evidentiary items,”13 and the “plain view”
    doctrine allows the arresting officers to seize incriminating evidence in their plain
    view at the time.14 But the government has not claimed, and the record does not

    Police may seize evidence in plain view without a search warrant if the

    13
    show, that the Marshals discovered appellant’s cell phone in the course of arresting
    appellant. And an arrest warrant is not a substitute for a search warrant.15 By
    itself, an arrest warrant does not authorize law enforcement officers to carry out a
    broader search of the arrestee’s dwelling for evidence; nor does it authorize them
    to remain inside the dwelling, or enter it, after they have removed the arrestee from
    it.16 So the fact that the Marshals had an arrest warrant did not justify their
    continuing presence or Detective Barton’s entry in appellant’s home after he had
    been arrested.
    Second, the actions of the Marshals or Detective Barton were not shown to
    be justified under the “protective sweep” exception to the requirement of a search
    warrant recognized in Buie. A protective sweep is not a search for evidence, nor is
    it a full search of the arrestee’s occupancy; it is “a quick and limited search of [the]
    (…continued)
    plainly seen,” the officer has “a lawful right of access to the object itself,” and the
    “incriminating character” of the evidence is “immediately apparent.” Horton v.

    And if the arrestee is apprehended outside the home or in the doorway, as

    premises, incident to an arrest and conducted to protect the safety of police officers
    or others. It is narrowly confined to a cursory visual inspection of those places in
    which a person might be hiding.”17 Thus, a protective sweep may “last[] no longer
    than is necessary to dispel the reasonable suspicion of danger and in any event no
    longer than it takes to complete the arrest and depart the premises.”18

    ; see also Young v United States, 
    982 A.2d 672
    , 681
    (D.C. 2009). There are two types of sweeps depending on the suspected source of
    the danger. The first allows the police to “look in closets and other spaces
    immediately adjoining the place of arrest from which an attack could be
    immediately launched,” even if they lack probable cause or reasonable suspicion to
    believe such an attack would occur. 
    Buie, 494 U.S. at 334
    . The second allows the
    police to search beyond immediately adjoining areas of the arrest, but only if they
    “possess[] a reasonable belief based on specific and articulable facts that the area
    to be swept harbors an individual posing a danger to those on the arrest scene.”

    was legal as part of a protective sweep because the officer was not yet “secure in
    the notion that no one was left in the apartment”); United States v. Davis,

    , 945 (8th Cir. 2006) (“The [protective] search should take no longer than

    The government has not claimed, and there is no evidence, that the Marshals
    discovered appellant’s cell phone in plain view (or otherwise) during their
    protective sweep of appellant’s residence. And Detective Barton confirmed at the
    suppression hearing that the sweep had ended before he arrived there, meaning the
    Marshals should have been gone from the residence by then. So the “protective
    sweep” exception to the warrant requirement did not justify the Marshals’
    continued presence or Detective Barton’s subsequent entry, and the government
    cannot (and did not) invoke this exception to justify the warrantless discovery of
    the cell phone.
    Third, “[i]t is well established that ‘exigent circumstances,’ including the
    need to prevent the destruction of evidence, permit police officers to conduct an
    otherwise impermissible search without first obtaining a warrant.”19       But the
    Marshals had no such justification after they removed all persons from appellant’s

    residence, and Detective Barton admittedly went inside for exploratory reasons
    having nothing to do with the existence of any exigency.
    That brings us to the fourth exception to the warrant requirement, the one on
    which the government relies. It contends the Fourth Amendment allowed the
    Marshals to impound appellant’s residence, pending the issuance of a search
    warrant, for the purpose of preventing unauthorized entrants from disposing of
    evidence there, and to seize incriminating items in plain view in the premises while
    they were doing so.20      There is authority supporting impoundment in such
    circumstances, but that does not mean it was lawful for the Marshals to remain
    inside the home after they had arrested appellant and removed all other persons
    who were present. Illinois v. McArthur21 teaches otherwise.
    In McArthur, police stood guard outside a suspect’s home and prevented the
    suspect from entering it unescorted while they waited for a warrant to search it.
    20
    It should be noted that the government did not establish either that the
    Marshals remained in appellant’s residence for this reason, or that their discovery
    of the cell phone while doing so satisfied the additional requirements of the “plain
    view” exception to the warrant requirement (besides the requirement of lawful
    presence). See footnote 
    14, supra
    . Appellant did not directly dispute these
    matters, however.

    17
    The police themselves did not enter the home except briefly to accompany the
    suspect (who was not yet under arrest) for the sole purpose of ensuring that he did
    not take the opportunity to destroy drugs concealed there. In order to determine
    whether this police conduct complied with the Fourth Amendment, the Court
    “balance[d] the privacy-related and law enforcement-related concerns to determine
    [whether] the intrusion was reasonable.”22        The Court concluded that “the
    restriction at issue was reasonable, and hence lawful, in light of the following
    circumstances, . . . consider[ed] in combination.”23 First, the police had probable
    cause to believe that the suspect’s home contained evidence of a crime.24 Second,
    the police had “good reason” to fear that the suspect would destroy the hidden
    drugs unless they restrained him.25     Third, and most significantly for present
    purposes, “the police made reasonable efforts to reconcile their law enforcement
    needs with the demands of personal privacy”; specifically, by staying outside the
    home except to escort the suspect in when he chose to reenter it, the police
    “imposed a significantly less restrictive restraint” and otherwise “left his home and

    his belongings intact.”26 Fourth, the police guard lasted for only a limited period of
    time, namely, two hours.27
    The contrast between the present case and McArthur is marked. In the
    present case, the Marshals did not “ma[k]e reasonable efforts to reconcile their law
    enforcement needs with the demands of personal privacy.” After the Marshals
    arrested appellant and cleared his home, their only law enforcement need was to
    prevent unwanted entrants from removing or destroying evidence inside the
    residence before a search warrant could be executed. The Marshals reasonably
    could have accomplished that goal with minimal impact on appellant’s privacy
    interests in his home by stationing a guard at the door and securing the premises
    from the outside.      They had no legitimate reason or need to stay inside the

    was a substantial additional invasion of his privacy, much greater than a stakeout
    outside the premises would have been; for, at a minimum, it exposed the interior
    and unconcealed contents of the home to the Marshals’ continuing scrutiny even if
    they refrained from formally searching the premises. By any measure, the balance
    of law enforcement-related and privacy-related concerns in this case compels the
    conclusion that the prolonged intrusion in appellant’s home was unreasonable and
    hence unlawful under the Fourth Amendment.
    Segura v. United States28 does not undermine that conclusion.           The
    government relies on the Court’s determination in Segura that a warrantless police
    intrusion into an arrestee’s home to secure it while a search warrant was procured
    did not violate the Fourth Amendment’s proscription against unreasonable seizures
    and therefore did not require suppression of evidence the police did not discover
    during the intrusion (and only discovered later during the execution of a valid
    search warrant). But that determination is inapposite to the present case, which
    concerns the applicability of the Fourth Amendment’s proscription against
    unreasonable searches to evidence—appellant’s cell phone—that the police did
    discover during a warrantless home intrusion. It was undisputed in Segura that the

    20
    warrantless police intrusion in that case did violate the Fourth Amendment’s
    proscription against unreasonable searches, and that this violation required any
    evidence the police discovered during the intrusion to be suppressed. Nothing in
    Segura supports a different conclusion in this case.
    In Segura, law enforcement agents had probable cause to believe Segura and
    Colon were trafficking in cocaine from their apartment.      The agents arrested
    Segura in the lobby of his apartment building, took him up to his apartment, and
    knocked on the door.        When Colon answered, the agents entered, “without
    requesting or receiving permission.”29 After informing those present that Segura
    was under arrest and a search warrant for the apartment was being obtained, the
    agents “conducted a limited security check of the apartment to ensure that no one
    else was there who might pose a threat to their safety or destroy evidence.” 30 In
    plain view in the bedroom, the agents observed drug trafficking paraphernalia. 31
    They then arrested everyone in the apartment. After the occupants were removed,
    two of the agents remained in the apartment for nineteen hours until a search

    warrant was procured.32 In executing that warrant, agents discovered additional
    drug trafficking evidence that they had not noticed during their pre-warrant
    incursion.
    The Supreme Court was concerned only with the admissibility of the
    additional, previously unseen evidence obtained pursuant to the search warrant.
    The government did not challenge the Second Circuit’s decision affirming the
    suppression of the evidence discovered before the warrant was obtained as the fruit
    of an unlawful search, and the Supreme Court stated it had “no reason to question
    the courts’ holding that that search was illegal.”33 “The only issue” before the
    Court was “whether drugs and other items not observed during the initial entry and
    first discovered by the agents the day after the entry, under an admittedly valid
    search warrant, should have been suppressed.”34
    The opinion for the Court majority concluded that the additional evidence
    found in executing the search warrant did not have to be suppressed as the fruit of

    either an unreasonable search or an unreasonable seizure. It was not the fruit of an
    unreasonable search, the opinion explained, because the search warrant was
    supported entirely by information having a source independent of the first, illegal
    intrusion; it was information known to the agents before they entered the
    apartment.35 And even if the first intrusion amounted to a seizure of the apartment
    and all its contents, “seen and unseen,” that seizure (viewed apart from the search)
    was not unreasonable either, given that the agents had probable cause and
    undertook only to “preserve the status quo” for the limited time required to obtain
    a search warrant.36
    The rationale for the latter conclusion was set forth in Part IV of the Court’s
    opinion.37 It reasoned that the illegality of the entry into the apartment did “not
    affect the reasonableness of the seizure,” because “[u]nder either method—entry

    (“Whether the initial entry was illegal or not is irrelevant
    to the admissibility of the challenged evidence because there was an independent
    source for the warrant under which that evidence was seized. Exclusion of
    evidence as derivative or ‘fruit of the poisonous tree’ is not warranted here because
    of that independent source.”).

    and securing from within or a perimeter stakeout—agents control the apartment
    pending arrival of the warrant; both an internal securing and a perimeter stakeout
    interfere to the same extent with the possessory interests of the owners,” 38 at least
    where the owners were already under arrest and in custody.39 But even so, Part IV
    emphasizes that “[d]ifferent interests are implicated by a seizure than by a
    search. A seizure affects only the person’s possessory interests; a search affects a
    person’s privacy interests.”40 Accordingly, Part IV acknowledges explicitly that
    the initial intrusion, though not an unconstitutional seizure, nonetheless “may have
    constituted an illegal search, or interference with petitioners’ privacy interests,
    requiring suppression of all evidence observed during the entry.”41              This
    necessarily included evidence in plain view of the intruding agents, because for the

    (“Here, of course, Segura and Colon, whose possessory
    interests were interfered with by the occupation, were under arrest and in the
    custody of the police throughout the entire period the agents occupied the
    apartment. The actual interference with their possessory interests in the apartment
    and its contents was, thus, virtually nonexistent. We are not prepared to say under
    these limited circumstances that the seizure was unreasonable under the Fourth
    Amendment.” (internal citation omitted)).

    plain view rule to apply, the police must be “lawfully located in a place from which
    the object can be plainly seen.”42
    Thus, on its face, Segura cannot be read as broadly holding that whenever
    the police need to safeguard evidence in an arrestee’s home pending the issuance
    of a search warrant, the Fourth Amendment permits them to enter or remain in the
    home and secure it from the interior in lieu of guarding it from the outside; or that
    evidence discovered in such warrantless intrusions will not be subject to
    suppression. Moreover, the Court’s subsequent decision in McArthur is plainly
    incompatible with such a reading of Segura.         At most, Segura supports the
    proposition that evidence not discovered during or by means of the unlawful
    warrantless intrusion to secure the premises may not have to be suppressed if it is
    discovered later through execution of a valid, untainted search warrant or other
    lawful means. Hence, we agree with Professor LaFave that, even in the wake of
    Segura, “if the only risk is loss of evidence by someone thereafter entering the
    premises, then the police may not take the more intrusive step of making entry into
    the premises and guarding it from within while the search warrant is obtained.”43

    Amendment § 6.5(c), at 556 (5th ed. 2012) (footnote omitted).
    25
    Although Professor LaFave speaks of “entry” by the police, the same rule logically
    applies when the police extend their stay in a dwelling after their right to be there
    under an exception to the warrant requirement expires.         In such non-exigent
    circumstances, absent other justification, the Fourth Amendment requires the
    police to guard the premises from the outside while awaiting a search warrant, and
    if a person with a possessory interest over the premises chooses to enter, as was the
    case in McArthur, the police constitutionally may escort that person inside only to
    ensure he does not remove or destroy evidence.
    We therefore conclude that the trial court erred as a matter of law in ruling
    that the Fourth Amendment permitted government agents without a search warrant
    to enter or remain in appellant’s home for the purpose of “seiz[ing] the scene to
    make sure that they could locate any evidence that may be connected to the
    offense” after the issuance of a warrant. Because the government has provided no
    other sufficient legal justification for the Marshals’ initial warrantless finding of
    the phone in appellant’s home, nor for their continued presence or Detective
    Barton’s entry in that home without a search warrant, we hold that these actions
    violated appellant’s Fourth Amendment rights.44
    44
    For two reasons, it would not be appropriate to give the government a
    second opportunity on remand to carry its burden of justification by attempting to

    26
    Our next step is to consider the consequence of that violation for this case.
    “It has long been the law that evidence collected in violation of the Fourth
    Amendment is considered ‘fruit of the poisonous tree’ and generally may not be
    used by the government to prove a defendant’s guilt.”45 To determine whether
    evidence can properly be classified as fruits, “the critical inquiry is whether ‘the
    (…continued)
    fill in the evidentiary record. First, the government had a full opportunity the first
    time around; it was on notice from the start that it would need to justify Detective
    Barton’s warrantless seizure of appellant’s phone, and the hearing made clear that
    appellant viewed the seizure as tainted by the unlawfulness of the Marshals’ and
    Detective Barton’s warrantless entry into the home. Second, the government has
    proffered no additional facts that it would seek to prove if the suppression hearing
    were reopened. See Evans v. United States, 
    122 A.3d 876
    , 885 (D.C. 2015) (“The
    United States had a full opportunity at the original suppression hearing to develop
    the factual record it deemed necessary to support the admissibility under the Fourth
    Amendment of the evidence at issue. We are not inclined to remand to give the
    United States a second opportunity to develop the record on this point.”). This is
    not a case in which the government’s omissions were caused by the defendant’s
    failure to emphasize an issue below. Cf. United States v. Hernandez-Mieses, 
    931 F.3d 134
    , 144 (1st Cir. 2019) (holding that although the court would “[o]rdinarily[]
    . . . not remand so that a party that failed to carry its burden (here, the government)
    would get a second chance to do so,” remand was appropriate where the appellant
    “b[o]r[e] some responsibility for the lack of focus by the government and the
    district court” on the legality of the protective sweep’s duration and scope at trial,
    because he did not highlight those issues before the trial court).

    evidence . . . has been come at by exploitation of th[e] illegality or instead by
    means sufficiently distinguishable to be purged of the primary taint.’”46
    Here, so far as record shows, the cell phone and cell phone data were come
    at by exploitation of what we have held to be unconstitutional conduct.47 Detective
    Barton relied on the Marshals’ unconstitutional discovery of the cell phone, and on
    his own unconstitutional entry, search, and discovery that the phone was not in
    appellant’s residence, to locate and seize the phone when he did. If the Marshals
    had never found the phone to begin with, there is no reason to suppose Detective
    Barton would have looked for it when he entered appellant’s home or would have
    found and seized it when he did; he relied on the Marshals’ report of their
    discovery.   Even assuming (without a basis in the record) that the Marshals
    lawfully discovered the phone, Detective Barton still would not have learned that
    the phone was missing had he not gone into the dwelling, and then he would not
    have searched for it inside the dwelling, discovered it in the hands of appellant’s

    We note that the government has not argued otherwise. Nor, either in the
    trial court or on appeal, has the government ever disputed the applicability of the

    girlfriend, and seized it from her. In short, the phone was seized as a direct result
    of what was learned through intrusions in appellant’s home that violated his Fourth
    Amendment rights.48
    However, that is not the end of the analysis. Exclusion of evidence is not
    necessarily mandated by the mere fact that it “would not have come to light but for
    the illegal actions of the police.”49 The Supreme Court has cautioned that “but-for
    causality is only a necessary, not a sufficient, condition for suppression.”50 We
    also must look to the totality of the circumstances to assess whether the evidence
    was purged of the primary taint, focusing on factors such as: (1) the “temporal
    proximity” of the illegality and acquisition of the fruits; (2) the existence of
    “intervening circumstances” causing the seizure of the fruits, such as an act of
    48
    Moreover, Detective Barton relied on his acquisition of the phone, and
    the information he obtained from it, to procure the search warrant allowing him to
    discover the incriminating contents of the phone. Unlike the search warrant in
    Segura, the warrant to search the cell phone seized from appellant’s girlfriend was
    not based entirely on an untainted, independent source. See also Murray v. United
    States, 
    487 U.S. 533
    , 542 (1988) (explaining that a search warrant cannot “in fact
    [be] a genuine[] independent source . . . if information obtained [through unlawful
    means] was presented to the Magistrate and affected his decision to issue the
    warrant”).

    independent free will on the part of the arrestee or a third party; and (3) “the
    purpose and flagrancy of the official misconduct.”51
    The first factor, temporal proximity, has no purgative effect in this case and
    counsels in favor of exclusion. “[V]ery little time passed between” the Marshals’
    and Detective Barton’s unlawful presence and search in appellant’s home and the
    detective’s seizure of the phone from appellant’s girlfriend; his search in the home
    for the phone led him directly and immediately to her.52
    The second factor, the existence of an intervening circumstance, likewise
    has no purgative effect because there was no such circumstance in this case.
    According to Detective Barton, appellant’s girlfriend did not offer his phone to him
    on her own initiative or of her own free will. Rather, the detective testified that he
    seized the phone from her after she confirmed it was appellant’s. Nor, as we have
    said, did the later issuance of a warrant to search the cell phone constitute an

    intervening circumstance that purged the primary taint of unlawfulness in the
    phone’s seizure, for the phone already had been seized and that fact was the
    predicate for the warrant’s issuance.53
    The third factor, the purpose and flagrancy of official misconduct, also does
    not operate to dispel the primary taint of the Fourth Amendment violation.
    Although the violation may not have been flagrant—the record does not show it to
    have been knowing or reckless—the fact remains that seizure of appellant’s cell
    phone was a primary aim of Detective Barton’s unjustified home intrusion, and it
    was only that violation that enabled Detective Barton to accomplish that aim.54
    Based on the totality of the circumstances, we conclude that appellant’s cell
    phone and cell phone data were obtained by exploitation of the Fourth Amendment

    136 S. Ct. 2056

    violation, not by sufficiently distinguishable means.      The trial court erred in
    denying appellant’s motion to suppress those fruits.
    The government argues that any error in admitting the cell phone evidence at
    trial was harmless. But we are not persuaded, as we must be, that this error was
    harmless beyond a reasonable doubt.55 “A prosecutor’s stress upon the centrality
    of particular evidence in closing argument tells a good deal about whether the
    admission of the evidence was . . . prejudicial.”56        At appellant’s trial, the
    prosecutor relied upon the evidence collected from appellant’s phone for roughly
    twelve percent of the government’s closing argument. The prosecutor emphasized
    this evidence to shore up the credibility of Mr. Williams’s roommate, Mr. Tillman,
    the only witness who could identify appellant as Mr. Williams’s assailant. Linking
    the calls to appellant’s phone from a contact named “Charlie” to the timeline of the
    crime, the prosecutor told the jury it was “not a coincidence” that, “[o]f all the
    people that could call the defendant within minutes of the murder,” the one who
    55
    In order to hold that an error implicating a federal constitutional right was
    harmless, we must be convinced that the error was “harmless beyond a reasonable
    doubt.” Chapman v. California, 
    386 U.S. 18
    , 24 (1967); Ellis v. United States,

    did so had the same name as the person Mr. Tillman had spoken of as appellant’s
    accomplice. The other evidence found in the search of appellant’s cell phone lent
    additional support to Mr. Tillman’s identification of appellant. The confirmations
    that the cell phone evidence supplied were critically important to the prosecution
    because Mr. Tillman had given false testimony in the past and his credibility was
    tarnished and in serious question throughout the trial.57 Given the evidentiary
    value of the cell phone evidence, and the importance placed on it by the
    prosecutor, we cannot conclude that its unconstitutional admission was harmless
    beyond a reasonable doubt.
    57
    Before Mr. Tillman took the stand, the judge instructed the jury that he
    had “provided false or perjured testimony while under oath in testifying in another
    proceeding in January 2016 that relates to the allegations in this case.” When the
    prosecutor questioned Mr. Tillman about this past untruthfulness, the judge paused
    to instruct the jury that it had “heard testimony that Mr. Tillman had admitted to
    testifying untruthfully at a prior proceeding” and it “should consider the testimony
    of someone who has admitted to perjury . . . with caution and scrutinize it with
    care.” The defense anchored its closing in arguments about Mr. Tillman’s perjury
    and general dishonesty. And in his final jury instructions, the judge reminded the
    jury that “[t]he testimony of an admitted perjurer . . . , in this case, Maurice
    Tillman, should be considered with caution and scrutinized with care.”
    33
    We therefore must reverse appellant’s convictions and remand for a new
    trial.
    So ordered.
    EASTERLY, Associate Judge, concurring: I agree entirely with Judge
    Glickman’s suppression analysis, but I would treat as conceded, in absence of any
    argument to the contrary by the government (or my dissenting colleague), the
    application of the exclusionary rule. See Robinson v. United States, 
    76 A.3d 329
    ,
    342 n.27 (D.C. 2013) (stating that, “just as the government bears the burden to
    demonstrate that it did not violate a defendant’s Fourth . . . Amendment rights, it is
    the government’s burden to prove attenuation” such that the exclusionary rule
    should not apply).
    FISHER, Associate Judge, dissenting: This is a challenging case made more
    difficult by an inadequate factual record and insufficient briefing. Before we issue
    such a consequential ruling, we should remand for a renewed evidentiary hearing
    and then require supplemental briefing.
    As I will explain later, the focus of this litigation shifted once it got in the
    hands of appellate judges. It is regrettable, but not surprising, that the record does
    34
    not answer many questions on which the court now has focused.              No one
    questioned that the warrant for appellant’s arrest authorized the marshals to enter
    his home and take him into custody. Payton v. New York, 
    445 U.S. 573
    , 602-03
    (1980). None of the marshals testified, and we do not know how or where they
    found appellant’s cell phone. There is no basis in the record for asserting, as the
    court does, that the marshals’ discovery of the phone was unconstitutional. Nor is
    there a factual basis for thinking that Detective Barton conducted an illegal search
    inside the home.
    The focus of the suppression hearing was outside the home — on the seizure
    of the cell phone from appellant’s girlfriend. Appellant was also requesting a
    hearing under Franks v. Delaware, 
    438 U.S. 154
    (1978), claiming that the
    government had misrepresented material facts when it applied for a separate
    warrant to search the phone. Although appellant’s counsel asserted orally that the
    marshals should have waited outside for the search warrant to arrive, and that
    Detective Barton entered the home illegally, those issues had not been briefed.
    This court’s opinion purports to distinguish Segura v. United States, 
    468 U.S. 796
    (1984), factually, but it does not squarely deal with the Supreme Court’s
    holding:
    35
    Specifically, we hold that where officers, having
    probable cause, enter premises, and with probable cause,
    arrest the occupants who have legitimate possessory
    interests in its contents and take them into custody and,
    for no more than the period here involved, secure the
    premises from within to preserve the status quo while
    others, in good faith, are in the process of obtaining a
    warrant, they do not violate the Fourth Amendment's
    proscription against unreasonable seizures.
    Id. at 798
    (emphasis added). The present case turns on whether that holding is still
    good law.
    It is simply wrong to say that “Illinois v. McArthur teaches otherwise.” Ante
    at 16. In fact, McArthur carefully avoided the question which had divided the
    Court in Segura — whether the police could lawfully secure the home from within
    while awaiting a search warrant. Rather than overruling Segura, the Court took the
    easy path home, noting that “both majority and minority [in Segura] assumed, at
    least for argument’s sake, that the police . . . might lawfully have sealed the
    apartment from the outside, restricting entry into the apartment while waiting for
    the warrant.” 
    McArthur, 531 U.S. at 333
    . There is obvious tension between the
    holdings of Segura and McArthur, but the Supreme Court has not resolved it.
    Nor have we benefitted from adversarial briefing on this important question.
    The government quoted Segura in its brief, but appellant did not even mention the
    36
    case. Appellant does cite McArthur in both of his briefs, but for a different
    proposition. Before holding that the marshals could not lawfully remain inside the
    house while awaiting the search warrant, we should ask both parties to brief the
    issue.
    If the marshals were lawfully securing the house from within, Detective
    Barton did not violate the Fourth Amendment by entering the home to join them.
    And he could take note of what was (or in this case was not) in plain view. Clark
    v. United States, 
    593 A.2d 186
    , 196-99 (D.C. 1991) (where initial entry was
    lawful, and responding officers remained in the premises for a reasonable time and
    were still there, crime scene search officer could enter and seize items in plain
    view); see also Porter v. United States, 
    37 A.3d 251
    (D.C. 2012) (applying Clark
    and remanding for an evidentiary hearing to clarify facts); Settles v. United States,
    
    615 A.2d 1105
    , 1112-13 (D.C. 1992) (applying the reasoning of Clark).
    But before we ask for supplemental briefing, we need to know more facts.
    Because the ground has shifted since the suppression hearing was held, we should
    remand for further proceedings.       See D.C. Code § 17-306 (“The District of
    Columbia Court of Appeals . . . may remand the cause and . . . require such further
    proceedings to be had, as is just in the circumstances.”).

    I respectfully dissent.
