G LICKMAN , Associate Judge : Gregory Green chall enges his convictions for armed robbery and felony murder while armed on several grounds. We need addres s 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 th is evidence was the fruit of an illegal search and seizure arising from the presence of la w enforcement agents in his home without a search warrant or other legal justification. Because w e 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. G reen’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 State s , 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).3
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 roo mmate, Mr. Tillman , heard the shooting, ran to the door, and made eye contact with a man who was standing ove r Mr. Williams’s body and going through his pockets to rob him. Mr. Tillman recogniz ed th is man as someone he knew from the neighborhood by the ni ckname “Face

. ” He told the police that “Face” was dressed in black and had on a dark hat with white lettering. Mr. Tillman also o bserved that “Face” was accompanied by a man wearing a red Helly
Hansen jacket

. He was uncertain of this second man’s identi ty 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 t hey entered the residence and removed the other4

persons who were there. 2 The Marshals then remained inside appellant’s home by themselves. T he record does not clarify what the Mars hals were doing in the home after having cleared the premises , or exactly when they eventually left

. The y did not have a search warrant for appellant’s home

.

A fter appellant was taken into custody , Metropolitan Police Department Detective Travis Barton wa s called to the scene. Detective Barton was the government’s only witness at the suppression hearing . He testified that o ne of the Marshals involved in appellant’s arrest in formed him when he arrived that appellant’s cell phone was on a couch in the livi ng 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 suppre ssion 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

. H e 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 l iving room couch and did not find it there

. The Marshals did not know what had happened to it. To find it, Detective Barton call ed appellant’s phone number

. 4 He heard a phone r i ng outside the house . Detective Barton went out and found the phone in the h ands of appellant’s girlfriend

. S he identified it as belonging to appellant , and the detective then seized it.

4 Detective Barton had o btained appellant’s phone number the day before the arrest.6

T he 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 obtaine d those numbers by taking off the phone’s back cover and removing its battery.

T h e 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 t he 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 H elly 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,
appe llant 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 seiz ure of his phone from his girlfriend “without the7

authori zation 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 de struction 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 d etective ha d 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 p urpose 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 Maryland 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, “curs ory” 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 t hat 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 warrant less 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 “fro m 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 whi le 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 locat e it, and then to seize it to prevent the loss or destruction of evidence. The government premised9

this argument on its contention that the Marshals were allowed to remain inside appellant’s home to secur e 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 th at 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 t his exigency

— t he risk that valuable evidence might be lost if the police could not find and recover the cell phone immediately

— j ustified the detective’s warrantless seizure of the phone , t he judge denied the motion to suppress the phone and the evidence obtained from i t

. The prosecution presented and relied on that evidence at trial.

II.

Appellant contends th at 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 fruit10

of the warrantless intrusion

. The government rejoins that the Marshals were justified in remaining in the premises to s ecure 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 Bart on’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 finding s 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 pro hibits “unreasonable searches and seizu res.” 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 Fo urth Amendment is [not] constricted ” and that our review of the trial court’s conclusions of law is de novo ).

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 estab lished 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 just ify 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 r emoving or destr oying 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 cas e (and have not

11 Mincey v. Arizona , 437 U.S. 385, 390 (1978) (quotation marks omitted).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

c ircumstances arising from an imminent threat of removal or destruction of evidence in the home

.

First, while t he 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 th e arrest. 12 W hile 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 arr esting officers to seize incriminating evidence in their plain view at the time. 14 But the government has not claimed, and the record does not

show, that the Marshals discovered appellant’s cell phone in the course of arrest ing appellant . And an arrest wa rrant 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 ; n or does it authorize the m to remain inside the dwelling , or e nter it , after the y 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 t he Marshals or Dete ctive 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 occ upancy; it is “a quick and limited search of [the]

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 lo n ger than it takes to complete the arrest and depart the premises .” 18

17 Buie , 494 U.S. at 327; see also Young v United States , 982 A.2d 672, 681 ( D.C. 2009). There are two types of sweeps depend ing 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 suspi cion 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 ar ea to be swept harbors an individual posing a danger to those on the arrest scene.” Id. at 337.

T he government has not claim ed , and there is no ev idence, 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 end ed before he arrived there , m eaning 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 di d 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 i mpermissible search without first obtaining a warrant.” 19 But the Marshals had no such justification after they removed all persons from appellant’s

19 Kentucky v. King , 563 U.S. 452, 455 (2011).16

residence , and Detective Barton admittedly went inside for exploratory reasons having nothing to do with th e existence of any exigency.

That brings us to the f

ourth exception to the warrant requirement , t he one on which the government relies. It contends the Fourth Amendment allowed the Marshals to impound appellant’s residence, pending the issuance of a se arch warrant, for the purpose of prevent ing unauthorized entr ants 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. McArthur 21 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.

21 531 U.S. 326 (200 1).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 [wheth er] 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 th e 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 eff orts 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 evi dence 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
fr om the outside. They had no legitimate reason or need to stay inside the residence for that purpose. And unnecessarily linger ing inside appellant’s dwelling

26 Id. ; see also id. at 331 (concluding that the impoundment and restriction on the suspect’s unaccompanied access to his home was reasonable, because it was
“ tailored to that need [to preserve evi dence] , being limited in time and scope,

. . . and avoiding significant intrusion into the home itself ”); id. at 337

- 38 (Souter, J., concurring) (“ When McArthur stepped outside and left the trailer uninhabited, the risk abated and so did the reasonableness of entry by the police for as long as he was outside. This is so because the only justification claimed for warrantless action here is the immediate risk, and the limit of reasonable response by the police is set by the scope of the risk. ”).

27 Id. at 33 2 (majority opinion).19

was a substantial additional invasion of his privacy, much greater than a stakeout outside the pr emises 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

- relate d 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 States 28 does not undermine that conclusion. The
governme nt 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 di d 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

concern s the applicability o f the Fourth Amendment’s proscription against
unreasonable searches to evidence

— a ppellant’s cell phone

— t hat the police did discover during a warrantless home intrusion

. It was undisputed in Segura that the

28 468 U.S. 796 (1984).20

warrantless police intrusion in that case did vio late 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 apartm ent 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 the ir pre - warrant incursi on.

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 eviden ce 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 fo und in executing the search warrant did not have to be suppressed as the fruit of

32 Id.

33 Id. at 798 (emphasis added)

. 34 Id. at 804; see also id. (“[N]o issue concerning items observed during the initial entry is before the Court.”).22

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 ent irely 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

and securing from within or a perimeter stakeout

— a gents 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 arr est 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 I V 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 th e entry.” 41 This necessarily included evidence in plain view of the intruding agents, because for the

38 Id. at 811 (Burger, C.J., joined by O’Connor, J.) (emphasis added)

. 39 See id. at 813 (“ Here, of course, Segura and Colon, whose possessory interests were interfered with by the occupation, were under arrest and in the cus tody 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 c ircumstances 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 broad ly 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 guar ding 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 mea ns. Hence, w e 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 guard ing it from within while the search warrant is obtained.” 43

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 w arrant 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 s earch warrant, we hold that the se 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 t o (continued...)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, “ t he critical inquiry is whether ‘the

... continue d) 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 tha t 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 reo pened. 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 th e 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 b efore the trial court).

45 Hooks v. United States , 208 A. 3 d 741 , 750 (D.C. 2019 ) (citing Wong Sun v. United States , 371 U.S. 471, 484 , 488 (1963)).27

evidence . . . has been c ome 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 uncon stitutional 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 h e 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 th eir discovery. E ven 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 search ed f

or it inside the dwelling , discover ed it in the hands of appellant’s

46 Jones v. United States , 168 A.3d 703, 721 (D.C. 2017) (quoting Wong Sun , 371 U.S. at 488 (quoting John Ma guire, Evidence of Guilt 221 (1959))).

47 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 exclusionary rule to the cell phone and cell phone data in this case in the event we were to reject its impoundment theory and find a Fourth Amendment violation for the reasons we do.28

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, t h at 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 causalit y 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 i llegality and acquisition of the fruits; (2) the existence of “intervening circumstances” causing th e 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 se arch 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 al so 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 i ssue the warrant ”).

independent free will on the part of the arrestee or a third party; and (3) “the purpose and flagrancy of the off icial 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 a nd 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 t here was no such circumstance in this case

. A ccording to Detective Barton, a ppellant’ 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 co nfirmed it was appellant’s. Nor , as we have said, did the later issuance of a warrant to search the cell phone constitute an

51 See Brown v. Illinois , 422 U.S. 590, 603

- 04 (1975).

52 See Jones , 168 A.3d at 723 (“First, as the search of Ms. Williams’s purse occurred at the scen e of Mr. Jones’s apprehension and arrest, very little time passed between the police’s unlawful cell

- site

- simulator search and their recovery of the evidence from Ms. Williams’s purse.”); Gordon v. United States , 120 A.3d 73, 86 (D.C. 2015) (“We observe th at virtually no time passed between the illegal seizure and the discovery of the warrant . . . .”).30

intervening circumstance that purged the primary taint of unlawfulness in the phone’s seizure, for the phone already had been seiz ed 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

— t he record does not show it to have been knowing or reckless

— t he 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 Ba rton 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

53 Cf. Utah v. Strieff

, 136 S. Ct. 2056, 2062 (2016) (explaining that a valid arrest warrant was a sufficient intervening circumstance because it “was entir ely unconnected with the [illegal] stop” (emphasis added)).

54 See Jones , 168 A.3d at 723 (“And third, although the police officers’ warrantless use of the cell

- site simulator here was not flagrant misconduct, recovery of Mr. Jones’s cellphone and the com plainants’ phones was undoubtedly one of the officers’ purposes in deploying the cell

- site simulator.” (footnote omitted)); Gordon , 120 A.3d at 86 (“[A]lthough the illegality was not flagrant, the officer’s purpose at the time of the seizure

— weighs in favor of suppression.”).31

violation , not by sufficiently distinguishable means

. T he trial co urt erred in denying appellant’s motion to suppress those fruits

.

The government argues that any error in admitting th e cell phone evidence at trial was harmless

. But we are not persuaded , as we must be, that this error was harmless beyond a reasonable do ubt. 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, t he prosecutor relied upon the evidence collected fro m 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 identif y appellant as Mr. Williams ’s assailant

. L ink ing 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 “har mless beyond a reasonable doubt.” Chapman v. California , 386 U.S. 18, 24 (1967); Ellis v. United States , 941 A.2d 1042, 1048

- 49 (D.C. 2008).

56 Morten v. United States , 856 A.2d 595, 602 (D.C. 2004) (internal quotation marks and brackets omitted).32

did so had the same name as the person Mr. Tillman had spoken of as appellant’s accomplice. T he other evidence found in the search of appellant’s cell phone lent additional support to Mr. Tillman’s identification of appellant

. Th e confirma tion s that the cell phone evidence supplied were critical ly 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 Befo re 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 question ed 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 admit ted 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.

E ASTERLY , 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 b urden to prove attenuation” such that the exclusionary rule should not apply).

F ISHER , Associate Judge , dissenting: This is a challenging case made more difficult by an inadequate factual record and insufficient briefing. Before we issue such a consequen tial 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 does34

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 w ith 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.

I d. 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
Co urt 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 argu ment’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 McAr thur , 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 the36

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 fro m 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 w as 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 rem anding 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 si nce 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 circumsta nces.”).37

I respectfully dissent.
