Before MATHESON , BALDOCK , and EID , Circuit Judges.

BALDOCK , Circuit Judge.
Following the unexpected death of Defendant Walt Shrum’s common law wife at the couple’s home around 5:30 a.m. on March 11, 2015, p olice officers in Kingman, Kansas “secured” the home, prohibiting Defendant acces s. Approximately three hours later and without access to his home, Defendant sig ned a consent tosearch form permitting an investigator from the Kingman County Sheriff’s Office (KCSO) to enter his home for the express purpose of retrieving his deceased wife’s medication in anticipation of an autopsy. While in the home, t he investigator saw ammunition in plain view inside an open bedroom closet. After returning to headquarters, the investigator learned Defendant was a convicte d felon and recalled seeing the ammunition in the closet. Several hours later, the investigator, based on what he had seen and learned, contacted a federal agent and ask ed him to obtain a search warrant for Defendant’s home. A federal magistrate judg e issued the warrant at 10:00 p.m. A late night search of the home, which local aut horities still would not permit Defendant to access, uncovered not only the ammuniti on but also two loaded firearms and 4.4 grams of suspected methamphetamine. A grand jury subsequently charged Defendant with two counts of being a felon in possession of a firearm in violation of 18 U.S.C. § 922(g)(1 ), one count of being a felon in possession of ammunition, again in violation of § 92 2(g)(1), and one count of possessing methamphetamine in violation of 21 U.S.C. § 844(a ). Following the district court’s denial of his motion to suppress the incrimina ting evidence used to charge him, Defendant entered a conditional guilty plea to one count of being a felon in possession of a firearm. After receiving a sentence of time served, Defendant appealed the district court’s denial of his motion to suppress. Our jurisdiction arises under 28 U.S.C. § 1291. This appeal presents us with two quest ions: Did the initial securing of Defendant’s home constitute an unreasonable seizure in violation of the
2Fourth Amendment? And if so, did such seizure taint the incrim inating evidence ultimately uncovered in the warrant search of his home? We ans wer both questions yes, and reverse.
I. The historical facts are not in dispute. Defendant and his wif e Candice Hill were at their home in the early morning hours of March 11, 2015 . Candice, who had just showered, was not feeling well. Shortly after telling Defendant she was very hot, she experienced a seizure and lost consciousness. At4:54 a.m., Defendant phoned 911 to report a medical emergency. Defendant informed t he 911 operator that Candice was thirty years old, was not breathing, and may h ave overdosed on prescription medication. Within five minutes, Captain Paul Hin ton of the Kingman Police Department (KPD) arrived on the scene. Defendant was pe rforming CPR on Candice in the bedroom. Captain Hinton relieved Defendant unti l EMS arrived at 5:11 a.m. About twenty-five minutes later, the ambulance, acco mpanied by everyone at the scene including Defendant, departed for the hospital a s hort distance away. Medical authorities pronounced Candice dead at 5:45 a.m. According to a “Crime Scene Entry Log Sheet,” KPD Sergeant Trav is Sowers “secured” Defendant’s home after arriving on the scene at 6:19 a.m. Sergeant Sowers next phoned Dustin Cooke, an investigator with the KCSO. A few minutes later, Investigator Cooke received a call from the KCSO assigni ng him the case. The police dispatch report indicates Investigator Cooke arrived at the hospital around
36:49 a.m. At the suppression hearing, Investigator Cooke testi fied as to the initial information he received on the incident: “I was told that they had a 30-year-old female that . . . it was initially a medical call, and that it needed to be investigated until otherwise; that it was nota suspicious death.” (emphasis added). Investigator Cooke asked Defendant, who had not yet returned ho me but remained at the hospital with Candice’s body, to accompany him to the Kingman County Law Enforcement Center to discuss the circumstances surr ounding her death. Defendant agreed. When later questioned about any information he may have had at this point regarding the cause of Candice’s death, Cooke res ponded, “I didn’t have anything.” Investigator Cooke escorted Defendant to a small in terview room where he began questioning him shortly after 7:00 a.m. The audio tap e recording of the interview reveals Defendant was coherent but frequently overwro ught with emotion. Cooke permitted Defendant to make and receive phone calls durin g the interview. About thirteen minutes into the interview, Defendant phoned a f emale friend he identified as Teresa. When Teresa told Defendant that she “mig ht be over sometime this morning,” Defendant stated, “I ain’t home yet because they ain’t lettin’ me go home yet. I’m up here at the Sheriff’s Office.” Defendant tol d Investigator Cooke that he wanted an autopsy performed to determine the cause of C andice’s death. The interview lasted until around 9:20 a.m. with a thirty minut e break beginning about 8:37 a.m. During the break, Investigator Cooke learned that the coroner had inquired about Candice’s medication as well as othe r medication in the
4home. Shortly after the interview resumed around 9:05 a.m., In vestigator Cooke told Defendant the autopsy was scheduled for 1:30 p.m. that day in n earby Wichita. Cooke stated he would need to retrieve Candice’s medication to determine if she took too many pills before she seized. He also told Defendant he wa nted to help Defendant get his dogs out of the home. Defendant said he woul d cooperate because he wanted to know why Candice died. He mentioned she may have overdosed on Adderall. Investigator Cooke told Defendant he was going “to a sk for your consent to get her medication.” Defendant responded with a question: “You gonna go with me?” Cooke answered, “Yeah, and we’re gonna go here in just a second.” Investigator Cooke also informed Defendant, “I’m gonna go aheadand hold onto your house as a scene, okay, until I get done with the aut opsy.” Defendant responded, “That’s fine, cause I told the landlord . . . and he said any way he could help me, he said don’t worry about nothin’.” At the supp ression hearing, Investigator Cooke described the discussion: Q. And at some point did you advise Mr. Shrum that you needed to hold onto the house, at least for that day? A. Yes. Q. Why did you say that? A. Just because there was a 36-year-old female that just goes into a code is not a common—it’s not a normal death. It does happen, but we have to investigate as to why that happened, so securing anything that may have given us information into that was the reason for the scene being held. Q. All right. And did you tell Mr. Shrum that you were going to need to hold onto the house for a little while? A. Yes I did.
5Q. And what was his response to that? A. Anything that I can do to help. . . . Investigator Cooke told Defendant he was “going to do what’s ca lled a consent to search and I’m just going in to retrieve the medication.” D efendant quickly responded, “I can’t do it unless I have an attorney go over it. ” Defendant then began to sob, “I wanna know what happened to her. I ain’t got nothin ’ to hide from you people. She’s my baby, she’s my everything. I know you have t o.” 1 For the next few minutes, Investigator Cooke and Defendant discussed Candice ’s ex-husband and family before Cooke returned to the topic of Defendant’s home: “Let’s run over to the house. Let’s get your dogs. Let’s get the medication.” D efendant suggested he feed his dogs and leave them in the house but Cooke told him th e dogs could not stay there: “I don’t want to leave them in the house not being take n care of.” Cooke explained to Defendant, “Well, I’m hoping that this is a tempor ary thing maybe not but through the end of this afternoon, um, to know what’s going on.” Defendant sobbed some more while he reminisced about Candice an d how much he missed her. Investigator Cooke again returned the conversation to Defendant’s home: “Let’s go get your dogs. Let’s get this med ication. And that way I can start moving forward with today and getting to the au topsy and getting the

1 At the suppression hearing, Investigator Cooke testified that after Defendant mentioned he wanted an attorney to review the consent form, Def endant “in what was a joking manner to me initially was, quote, ‘Shit, I’m justkidding,’ and we moved on.” Defendant’s reported statement is inaudible on the interview tape. 6meds to the doctor and stuff like that . . . .” Defendant agai n expressed concern that Candice may have taken too many pills and told Cooke one of hermedicine bottles was empty. Investigator Cooke asked if the empty bottle was in the house and Defendant said he believed so. Cooke inquired as to the locati on of the bottle, reminding Defendant, “I can’t let you go in the house. I’ll ju st tell you I can’t let you go in the house, but if you’ll tell me where that stuff is. ” Defendant responded that his medication was on the kitchen counter and Cooke stated he wanted to retrieve Defendant’s medication as well. The two men then disc ussed the location of Candice’s medication. Defendant thought it might be on the bedside table in the master bedroom. Investigator Cooke stated: “I’ll look whe n we get over there but I want you to go with me. I’ll have you sign this consent so I can get your medication, her medication, . . . .” The KPD Crime Scene Entry Log shows Investigator Cooke, Defenda nt, and Defendant’s friend, Denise Niederman, arrived at Defendant’s ho me at 9:30 a.m. Investigator Cooke placed the consent to search form on the hoo d of his squad car. Cooke wrote “Retrieve Medication” on the form. He read and exp lained the form to Defendant. Defendant indicated he understood, signed the form, and provided Cooke a key for entry. At some point, Defendant asked Investigator C ooke if he could go inside his home to urinate. Cooke said no and later acknowledg ed he forced Defendant to “relieve himself outside the house where there wer e other people standing around.” Once inside the home, Investigator Cooke letthe dogs out and
7retrieved Defendant’s walking stick. Consistent with the information he obtained from Defendant during the interview, Cooke found prescription m edication in the kitchen and in the master bedroom. Cooke gave Defendant his me dication and kept Candice’s medication for the coroner. Investigator Cooke was inside Defendant’s home between ten and fifteen minutes. The entry log shows Cooke departed the scene at 10:05 a.m. while Defendant and Niederman departed at 10:07 a.m. The log indicat es Cooke entered the home to “retrieve medications / dogs.” Neither Defendant n or Niederman were permitted to enter the home. While in the home, Cooke took fif ty-six photographs of the kitchen and bedroom from various angles. 2 One of the photographs depicted ammunition in plain view in the bedroom closet. Cooke testifie d the closet door was open when he entered the bedroom. Back at headquarters prior t o the scheduled autopsy, another officer reminded Cooke that Defendant was a co nvicted felon: Q. At some later point did you realize that Mr. Shrum was a convicted felon? A. I did, and there was two things that kind of sparked that: One, you heard in the interview where it come to my recollection and he even said it was almost six years ago that he and I had talked; and then the other officer that actually was assigned to that case made a comment, he says, you know, I think he was a felon and then it dons [sic] on me, wait a second, I saw ammo in the house. So I go back to my pictures and I’m like, there’s the

2 Investigator Cooke testified he took the photographs to (1) d ocument the items he collected and (2) document that he did not remove item s other than medication from the home. 8ammunition, and that’s what led into this investigation.[ 3 ] Investigator Cooke attended Candice’s autopsy in Wichita that a fternoon at 1:30 p.m. 4 The autopsy lasted approximately two hours. That evening, Co oke contacted Agent Neil Tierney from the Wichita branch of the Bur eau of Alcohol, Tobacco, Firearms, and Explosives (ATF). Cooke asked Tierney t o obtain a search warrant for Defendant’s home based on the ammunition in Defenda nt’s closet and his status as a convicted felon. A federal magistrate judge is sued the warrant at 10:00 p.m. The Crime Scene Entry Log indicates three ATF agent s, including Agent Tierney, accompanied by Investigator Cooke and Sergeant Sowers, executed the warrant beginning at 11:18 p.m. The search concluded at 1:20 a .m. on March 12, 2015. According to the Justice Department’s “Report of Investi gation,” law enforcement seized the following items from Defendant’s home: ( 1) a loaded 12- gauge pump shotgun, (2) a loaded .45-caliber semi-automatic rif le, (3) an additional 806 rounds of live ammunition, (4) six glass paraphernalia pipe s with residue, and (5) approximately 4.4 grams of suspected methamphetamine.
II.

3 Defendant’s Presentence Report indicates he was convicted in 2001 of making false statements to the federal government and in 2003 o f being a felon in possession of a firearm. In 2010, Defendant’s criminal conduct came to the attention of the KPD when he was charged with misdemeanor theft of a lawn mower by deception.

4 According to the district court, the autopsy found the cause of Candice’s death to be methamphetamine intoxication. 9Prior to the suppression hearing, the focus of Defendant’s moti on to suppress was his purported consent to search the home and the scope of t his consent. But Defendant also argued, albeit inartfully, that law enforcement illegally seized his home immediately after Candice’s death. Following the hearing, the district court provided some “preliminary thoughts” to the parties that also f ocused on Defendant’s consent and its scope. When asked if additional briefing was n ecessary before the court rendered its decision, defense counsel reminded the courtthat one of Defendant’s prior arguments was that the police se ized his home without a warrant from very early in the morning until very late at night on the day of Candice’s death: “I would submit . . . that a big part of the motion is not just what happened inside [the home], . . . but the bottom line is . . . that they secure d that house, prevented [Defendant] access, . . . and that simply cannot be done withou t a warrant . . . .” The court subsequently granted Defendant’s request for further briefing. In his supplemental brief, Defendant quoted directly from the Supr eme Court’s decision in Segura v. United States , 468 U.S. 796, 804–05 (1984), which in turn quoted from Wong Sun v. United States , 371 U.S. 471, 488 (1963): Evidence obtained as a direct result of an unconstitutional sea rch or seizure is plainly subject to exclusion. The question to be re solved when it is claimed that eviden ce subsequently obtained is “tain ted” or is “fruit” of a prior illegality is whether the challenged evid ence was “come at by exploitation of [the initial] illegality or insteadby means sufficiently distinguishable to be purged of the primary taint.” (citation omitted) (brackets and emphasis in original). Defend ant concluded by

10explaining: “Although Segura ultimately upheld the search in that case, its analysis and reasoning support an opposite conclusion here . . . . The later search is indelibly tied to the initial illegal seizure of [Defendant’s] home . . . .” 5 In denying Defendant’s motion to suppress, however, the distric t court never asked whether an illegal seizure tainted Defendant’s consent to search and the incriminating evidence Investigator Cooke witnessed as a conseq uence thereof, a taint in turn sufficient to invalidate the subsequent search wa rrant and its “fruits.” Instead, the court held the seizure of Defendant’s home did notviolate the Fourth Amendment 6 : [G]iven the unexpected death of [Candice], the subsequent establishment of probable cause after Investigator Cooke observ ed the ammunition and learned of defendant’s felon status, and the tim e it took to coordinate between state and federal law enforcement to secu re a search warrant, the court finds that the “seizure” of defendant ’s residence was reasonable under the Fourth Amendment.

5 Wong Sun , of course, established the “ fruit of the poisonous tree” doct rine which we will have more to say about shortly. In Segura , the Supreme Court rejected application of the doctrine and held that despite an i llegal entry into a home, the Fourth Amendment did not require suppression of evidence se ized later from the home pursuant to a valid search warrant issued on information t he police obtained before entry into the home. “[T]he exclusionary rule has no applicati on where the Government learned of the evidence ‘from an independent source. ’” Segura , 468 U.S. at 805 (brackets omitted) (quoting Wong Sun , 371 U.S. at 487).

6 The district court also held Defendant’s subsequent consent t o a limited search of his home was knowing and voluntary, and Investigator Cooke did not exceed the scope of this consent by photographing the interior of Defendant’s home. The court concluded, however, that even if Cooke exceeded the s cope of Defendant’s consent by taking photos, Cooke’s observation of the ammunition alone, apart from any photographs, established probable cause for issuance of the search warrant. 11III. The Fourth Amendment provides in relevant part: “The right of the people to be secure in their persons, houses, papers, and effects, aga inst unreasonable searches and seizures, shall not be violated, and no Warrants s hall issue, but upon probable cause . . . .” U.S. Const. amend. IV. A defendant se eking to suppress evidence based on a warrantless seizure of his property bears t he burden of proving the same. 7 United States v. Carhee , 27 F.3d 1493, 1496 (10th Cir. 1994); see also United States v. Hernandez , 847 F.3d 1257, 1263 (10th Cir. 2017) (recognizing that a defendant bears the burden of proving whether and when the Fo urth Amendment was implicated). If the defendant meets his burden of establis hing a warrantless seizure, the burden then shifts. The Government must establish the warrantless seizure was reasonable. Carhee , 27 F.3d at 1496; see also United States v. Finefrock , 668 F.2d 1168, 1170 (10th Cir. 1982) (recognizing that when a defendant challenges a warrantless seizure, the Government bears the burd en of justifying its actions). Where, as here, the underlying facts are undisputed, we review de novo the question of whether those facts establish a warrantless seizure within the meaning of the Fourth Amendment and, if necessary, the question of when such seizure occurred. United States v. Roberson , 864 F.3d 1118, 1121 (10th Cir. 2017). We also review de novo the ultimate determination of reasonableness und er the Fourth

7 The controlling standard of proof at a suppression hearing is proof by a preponderance of the evidence. Nix v. Williams , 467 U.S. 431, 444 n.5 (1984). 12Amendment. United States v. De La Cruz , 703 F.3d 1193, 1195–96 (10th Cir. 2013).
A. The Supreme Court has told us a Fourth Amendment “seizure” occu rs “when there is some meaningful [government] interference with an indi vidual’s possessory interests in . . . property.” United States v. Jacobsen , 466 U.S. 109, 113 (1984); see also United States v. Hill , 805 F.3d 935, 937 (10th C ir. 2015). Given the Supreme Court’s description of a seizure, we have little difficulty con cluding local law enforcement in Kingman, Kansas seized Defendant’s home no laterthan 7:02 a.m. on March 11, 2015. The police dispatch report indicates Sergea nt Sowers arrived at Defendant’s home at 6:19 a.m. The KPD Crime Scene Entry Log in dicates he promptly began securing the scene upon arrival. According to t he dispatch report, the police were still “securing [the] scene” at 7:00 a.m., and had commenced a “criminal death investigation” by 7:02 a.m. By this time if no t before, the police had asserted “dominion and control” over Defendant’s home (and effe ctively everything within it) as part of their investigation into Candice’s death

. See Jacobsen , 466 U.S.
at 120 & n.18. The Government says the police “understandably” secured Defenda nt’s home from the outside. The police never entered the interior of Def endant’s home, let alone searched it, prior to Defendant’s subsequent consent to s earch. But how these observations bear on the question of whether a Fourth Ame ndment seizure—defined as a meaningful interference with an individual ’s possessory
13interests in property—occurred when police secured Defendant’s home immediately following Candice’s death escapes us. We see little difference between a perimeter stakeout and internal securing of a home from the standpoint of a Fourth Amendment
seizure . Both interfere to the same extent with the possessory intere sts of those entitled to occupy the dwelling. See Segura , 468 U.S. at 811 (plurality). The Government cannot reasonably dispute that the “securing” of Def endant’s home during the early morning hours of March 11, 2015 infringed not only on his possessory interest in the home but also on his liberty interes t in free movement. See United States v. Place , 462 U.S. 696, 708 (1983). The police deprived Defendant of his ability to access his home for his own purposes, in his own way, on his own time, and at a location where concerned friends and well-wishers woul d surely come calling. Cf. California v. Hodari D. , 499 U.S. 621, 624 (1991) (“From the time of the founding to the present, the word ‘seizure’ has meant a “ta king possession[.]”). The Supreme Court reminded us just this past term that “when it comes to the Fourth Amendment, the home is first among equals. At the Amend ment’s very core stands the right of a man to retreat into his own home and ther e be free from unreasonable governmental intrusion.” Collins v. Virginia , 138 S. Ct. 1663, 1670 (2018) (citations and quotation marks omitted); see also Wong Sun , 371 U.S. at 484 (recognizing the “fundamental constitutional guarantee[] of san ctity of the home”). The right to retreat into one’s abode following the unexpected death of a loved one would ring hollow if law enforcement could simply “secure” the home under the
14auspices of a “criminal” investigation and exclude one therefro m without constitutional implication upon the, in the words of Investigat or Cooke, “not normal” death of a household member. “‘[A] man’s house is his castle,’ whether it is under siege by police officers prying into his possessions stored wit hin or whether they exclude him from its sanctuary.” United States v. Song Ja Cha , 597 F.3d 995, 1002 (9th Cir. 2010) (citation omitted) (quoting Payton v. New York , 445 U.S. 573, 598 (1980)).
B. Of course, not every seizure at the hands of government officia ls violates the Fourth Amendment. Only unreasonable seizures are proscribed. Brigham City v.
Stuart , 547 U.S. 398, 403 (2006) . At its inception, a seizure must b e reasonable to comport with the Fourth Amendment. Roberson , 864 F.3d at 1121. The seizure must then remain reasonable “throughout its duration and in the enti rety of its scope.” United States v. Martinez , 518 F.3d 763, 766 (10th Cir. 2008). The reasonableness of police conduct turns on the facts and circumstances of each case viewed in the light of established Fourth Amendment principles. Ohio v. Robinette , 519 U.S. 33, 39 (1996); see also United States v. Rabinowitz , 339 U.S. 56, 83 (1950) (Frankfurter, J., dissenting). In particular, to determine whether the seizu re of Defendant’s home in this case was reasonable we need look no further than the Fo urth Amendment principles established in Illinois v. McArthur , 531 U.S. 326 (2001).
In McArthur , the complaining witness told a police officer that the defend ant, 15her ex-boyfriend, had “dope” in his trailer. When the defendan t refused the officer’s request to search, the officer told the defendant, who was outs ide the trailer, that he could not reenter the trailer unless accompanied by an officer. Another officer returned with a search warrant less than two hours later. The search uncovered a small amount of marijuana under the sofa. The defendant moved to suppress this evidence, reasoning the evidence was the “fruit” of the unlawfu l seizure of his trailer. The Court held, however, that a police officer could lawfully prevent the defendant from entering his trailer while another officer dilig ently obtained a search

warrant. Id. at 328. The Court explained that excluding the defendant fromhis trailer was reasonable in light of the following circumstances: (1) the police had probable cause to believe the defendant’s trailer contained evi dence of a crime, namely his possession of illegal drugs; (2) the police had goodreason to fear the defendant might destroy the evidence before they procured a war rant; (3) the police, by only preventing the defendant from entering his trailer unac companied, made reasonable efforts to reconcile their law enforcement needs wit h the demands of personal privacy; and (4) the police excluded the defendant fro m his trailer for a limited time, namely two hours. Id. at 331–33. McArthurplainly teaches us a police officer armed with probable cause to believe a home contains evidence of a serious crime that might otherwise be destroyed may lawfully secure the home and restrict entry while waiting for an assisting officer to diligently pr ocure a search warrant. See id. at 333–34; see also
16Segura , 468 U.S. at 798. But here, unlike in McArthur , the Government has never suggested that probable cause (or any form of articulable suspi cion for that matter) justified the initial seizure of Defendant’s home. And we have news for the Government. No such thing as a “crime scene exception,” let al one an “unexplained death scene exception,” to the Fourth Amendment exists. See Flippo v. West Virginia , 528 U.S. 11, 13–14 (1999) (declining to recognize a crime sce ne exception to the Fourth Amendment). In the context of a home seizure, “t he mere fact that law enforcement may be made more efficient can never by itself just ify disregard of the Fourth Amendment[’s]” probable cause requirement. Mincey v. Arizona , 437 U.S. 385, 393 (1978) (holding a warrantless search of the defendant’ s apartment was not permissible simply because a murder recently occurred there). Neither, unlike in McArthur , has the Government ever suggested that some sort of exigency justified the seizure of Defendant’s home. Ab sent valid consent, the warrantless seizure of a home even in the presence of probable cause “is per se unreasonable, unless the police can show that it falls within o ne of a carefully defined set of exceptions based on the presence of ‘exigent cir cumstances.’” Coolidge v. New Hampshire , 403 U.S. 443, 474–75 (1971); see also Brigham City , 547 U.S. at 403. At the suppression hearing, Investigator Cook e stated that when Defendant’s home was “secured” on the morning of Candice’s deat h, he “didn’t have anything” other than a death that was “not normal.” Moreover, Cooke previously explained that the initial report he received was “it was not a suspicious death.” In
17other words, the police, according to the record before us, had no knowledge of any facts suggesting Defendant or his now-deceased wife were engage d in criminal wrongdoing inside their home. And at least in the context of F ourth Amendment jurisprudence, the police certainly neverhave good reason to fear the destruction of incriminating evidence of which they have no particularized kno wledge. Nor did the police in this case, again unlike in McArthur , make any effort to reconcile their law enforcement needs with Defendant’s Fourth A mendment interests in his home as a place of refuge, privacy, and comfort. See Place , 462 U.S. at 703. This seizure was not minimally intrusive; rather it was the com mencement of a fishing expedition to see what sort and how big of fish the pol ice might catch. The police completely disregarded Defendant’s constitutional rights and seized his home so they could find out, again in the words of Investigator Cook e, “what’s going on.” Inexplicably, Cooke would not even allow Defendant supervised e ntry into his own home to urinate. For reasons unclear to us apart from Investig ator Cooke’s preference and convenience, the seizure extended over a period of eighteen hours even though probable cause arose sometime around 11:00 a.m. or about four hours into the investigation. By then, Cooke had seen the ammunition inside the bedroom closet and learned of Defendant’s felony status and had all the probable cause he needed to procure a search warrant. ATF agents at the behest o f Cooke, however, did not procure a warrant until eleven hours later or 10:00 p.m

. In addition to Candice’s unexplained death, which in itself was no basis for
18seizing Defendant’s home, the district court provided two ex po st facto rationales to justify the initial seizure. The first rationale was “the subs equent establishment of probable cause after Investigator Cooke observed the ammunition and learned of defendant’s felon status.” In answer to this we can only say a Fourth Amendment seizure unlawful at its inception “does not change character fr om its success.” United States v. Di Re , 332 U.S. 581, 595 (1948). The initial legality of a seizure turns on the facts and circumstances known to the police at the time of the seizure rather than on facts and circumstances subsequently discovered. United States v.
Cantu , 405 F.3d 1173, 1178 (10th Cir. 2005); see also Wong Sun , 371 U.S. at 484 (recognizing the Supreme Court has “consistently rejected” the proposition “that a search unlawful at its inception may be validated by what it tu rns up”). The court’s second rationale to justify the seizure was “the ti me it took to coordinate between state and federal law enforcement to secure a search warrant.” As for this rationale, we simply observe that the time taken to procure a warrant to search a previously seized home has no bearing on the legali ty of the home’s
initialseizure. Rather, the time taken to procure a warrant bears up on the continuing reasonableness of a seizure reasonable at its inception. See Segura , 468 U.S. at 812 (plurality) (recognizing a seizure reasonable at its incept ion may become unreasonable as a result of its duration); see also United States v. Villa-Chaparro , 115 F.3d 797, 801–03 (10th Cir. 1997) (separately addressing th e questions of whether a seizure was reasonable at its inception and whether t hat seizure became
19unreasonable based on its duration). The time taken to procure a warrant, no matter how brief, does not turn a seizure unreasonable at its inceptio n into a reasonable seizure. An unreasonable warrantless seizure of one’s home, th at is, a seizure unsupported by probable cause and exigent circumstances at the outset, does not become reasonable based on after-the-fact rationales.
IV. Having held without any difficulty that law enforcement’s initi al securing of Defendant’s home on the morning of Candice’s death constituted an unreasonable seizure in violation of the Fourth Amendment, we are now prepar ed to consider the effect of this illegal seizure on what followed. 8 A defendant has the initial burden of establishing a causal connection between an illegal seizure and the evidence he seeks to suppress. United States v. Torres-Castro , 470 F.3d 992, 999 (10th Cir. 2006). Specifically, the defendant must establish the incrimin ating evidence “would not have come to light but forthe illegal [seizure].” Wong Sun , 371 U.S. at 488 (emphasis added). “But for” causation, however, is only a nece ssary condition for suppression; it is not sufficient. Torres-Castro , 470 F.3d at 999. Once a defendant establishes “but for” causation, the Government may still avoid suppression. Id. At this point, the relevant inquiry becomes whether the Governmenthas proven the

8 Quite frankly, this would have been a much more straightforwa rd case both in the district court and here if the Government had conceded t he obvious, that is, the unconstitutionality of the initial seizure of Defendant’s home. 20incriminating evidence was discovered by means sufficiently dis tinguishable from the initial illegality to be purged of the primary taint. Wong Sun , 371 U.S. at 488. This latter inquiry is tied to the aims and costs of the exclus ionary rule. “The fact that a Fourth Amendment violation occurred . . . does not necessarily mean that the exclusionary rule applies.” Herring v. United States , 555 U.S. 135, 140 (2009). The exclusionary rule is not a constitutional right but a prude ntial doctrine that the Supreme Court has created to compel respect for Fourth Amendmen t guarantees. Davis v. United States , 564 U.S. 229, 236 (2011). “The rule’s sole purpose . . . is to deter future Fourth Amendment violations.” Id. at 236–37. Before exclusion is appropriate, the deterrence benefits of suppression must out weigh the rule’s “costly toll upon truth-seeking and the law enforcement objecti ves” of apprehending criminals and protecting the public. Herring , 555 U.S. at 141. Where an unlawful seizure of a home precedes a “consensual” sea rch of the home and the discovery of incriminating evidence then used to p rocure a search warrant, the Government’s burden to prove the primary taint of the illegality has been purged, i.e. , that the search warrant and its “fruits” are valid, is two-fo ld. See Murray v. United States , 487 U.S. 533, 540 (1988) (recognizing that evidence discovered as a result of an unlawful entry “cannot be used to establish probable cause before a magistrate”). The Government must prove the vol untariness of a defendant’s consent consistent with the principles set forth in Schneckloth v.
Bustamonte , 412 U.S. 218 (1973). But in addition, the Government must
21demonstrate a break in the causal chain somewhere between the i llegality and discovery of the incriminating evidence used to support the def endant’s prosecution. United States v. Fox , 600 F.3d 1253, 1257 (10th Cir. 2010). Professor LaFave explains that while the Government’s dual burdens may overlap, “it is extremely important to understand that (i) the two tests are not identica l, and (ii) consequently the evidence obtained by the purported consent should be held a dmissible only if it is determined that the consent was both voluntary and not an exploitation of prior illegality.” Wayne R. LaFave, Search and Seizure: A Treatise on the Fourth Amendment § 8.2(d) at 101 (5th ed. 2012) (emphasis in original) . This means “the fruit of the poisonous tree doctrine [may] also extend[] to inv alidate consents which

are voluntary” in the traditional sense. 9 Id. § 8.2(d) at 102 (emphasis in original); see Florida v. Royer , 460 U.S. 491, 495, 501, 507–08, 509 (1983) ( plurality plus Brennan, J., concurring) (holding an illegal seizure of the def endant tainted his subsequent consent to search without questioning the trial court’s ruling that his consent was “freely and voluntarily given”). We require th e Government to demonstrate a break in the causal chain for two reasons. United States v. MelendezGarcia , 28 F.3d 1046, 1054 (10th Cir. 1994). First, we are concerned the illegal seizure may have affected the voluntariness of the defendant’s consent that led to

9 In Schneckloth , the Supreme Court addressed the question of “what must the prosecution prove to demonstrate that a consent was ‘volunt arily’ given.” Schneckloth , 412 U.S. at 223. Notably no police misconduct preceded the c onsent to search in that case. 22discovery of the incriminating evidence. Id. (recognizing the Government has a “heavier burden” to carry when consent follows an illegal seizu re). Second, we are bound, where appropriate, to effectuate the exclusionary rule’s deterrence principle.
Id.
A. Because here the historical facts are undisputed and the recordof the district court proceedings, which includes Investigator Cooke’s taped in terview with Defendant, was adequately developed, we exercise our discretion to proceed. 10 Accordingly, let us commence the proper analysis by considering whether Defendant has established “but for” causation. Justifiably apart from an y unwarranted speculation about what might have transpired if the police had not unlawfully seized Defendant’s home, Defendant can easily meet his burden to show that but for the illegal seizure, law enforcement would not have discovered the incriminating evidence he seeks to suppress. If Defendant is allowed to acce ss his home and

10 We have explained that because the district court held the in itial seizure of Defendant’s home complied with the Fourth Amendment and his sub sequent consent to search was knowing and voluntary, the court did not ask whet her the challenged evidence was “come at by exploitation of [the initial] illegali ty or instead by means sufficiently distinguishable to be purged of the primary taint. ” Wong Sun , 371 U.S. at 488 (quotation marks omitted). Nonetheless, because proceed ings in the district court “resulted in a record of amply sufficient detail and dept h from which th[is] determination may be made,” we decline to remand this case so t hat the district court may undertake the proper analysis in the first instance. Brown v. Illinois , 422 U.S. 590, 604 (1975); accord United States v. Fernandez , 18 F.3d 874, 881 n.7 (10th Cir. 1994). 23retrieve the medication himself, Investigator Cooke’s entrance into the home to retrieve the medication pursuant to Defendant’s consent to sear ch is unnecessary. Absent entry into the home, Investigator Cooke neversees the ammunition he necessarily relied on to prompt the ATF to procure the search warrant, the execution of which led directly to the incriminating evidence used to pro secute Defendant. Next, we must determine whethe r the Government may avoid suppre ssion of the evidence notwithstanding the illegal seizure of Defendant’s home. Inevitably, our analysis at this stage becomes much more complex. Setting aside the question of whether Defendant’s consent was voluntary in the traditional sense under the principles established in Schneckloth , we turn our attention to that part of the Government’s burden requiring it to break the causal chain. Th ree exceptions to the exclusionary rule address the “causal relationship between the unconstitutional act and the discovery of evidence.” Utah v. Strieff , 136 S. Ct. 2056, 2061 (2016). Two of these exceptions, however, do not address whether the taint has been purged despite “but for” causation, but rather bear upon “but for” cau sation itself. The independent source doctrine permits courts to admit evidence no twithstanding a prior illegality if law enforcement acquired the incriminating eviden ce from a separate, independent source. Id. The inevitable discovery doctrine countenances the admission of evidence that would have been discovered regardles s of prior police illegality. Id. ; see Murray v. United States , 487 U.S. 533, 539 (1988) (recognizing the latter doctrine “is in reality an extrapolation” of the for mer doctrine because if
24“the tainted evidence would be admissible if in fact discoveredthrough an independent source, it should be admissible if it inevitably wo uld have been discovered” through such a source). In this case, nothing in the record remotely suggests law enfor cement obtained the incriminating evidence against Defendant from an independen t source, i.e. , a source wholly separate from the illegal seizure of Defendant’s home and what followed therefrom. See Segura , 468 U.S. at 815 (applying the independent source doctrine because the unlawful entry into the home “did not cont ribute in any way to discovery of the evidence seized under the warrant”). Addition ally, any suggestion that the police inevitably would have discovered the incriminat ing evidence against Defendant had they not initially seized his home and prohibited him access is far too speculative. “[I]nevitable discovery involves no speculative e lements but focuses on demonstrated historical facts capable of ready verification . . . .” Nix v. Williams , 467 U.S. 431, 444 n.5 (1984). What would have transpired had t he police not illegally seized Defendant’s home from the outset and denied hi m access is anybody’s guess. This leaves us to examine the third exception to the exclusionary rule bearing upon causation—the attenuation doctrine. The notion of attenuation or “‘dissipation of the taint’ [of th e prior illegality] attempts to mark the point at which the detrimental consequence s of illegal police action become so attenuated that the deterrent effect of the ex clusionary rule no longer justifies its cost.” Brown v. Illinois , 422 U.S. 590, 609 (1975) (Powell, J.,
25concurring in part). This exception may apply even in the pres ence of “but for” causation. Attenuation occurs “when the connection between the unconstitutional police conduct and the evidence is remote or has been interrupt ed by some intervening circumstance so that the interest protected by the constitutional guarantee that has been violated would not be served by suppression of th e evidence obtained.” Strieff , 136 S. Ct. at 2061. The factors the Supreme Court articulated in Brown and reiterated in Strieff guide our determination of whether the illegal seizure of Defen dant’s home tainted the incriminating evidence or whether such taint has been purge d. Brown , 422 U.S. at 603–04; Strieff , 136 S. Ct. at 2061–62. First, we consider the temporal proxi mity between the illegal seizure and discovery of the incriminating evidence used to prosecute Defendant to determine whether time has rendered the connection between the illegality and the evidence remote and suppression inapprop riate. Strieff , 136 S. Ct. at 2062. Second, we look for the presence of any interveni ng circumstances during this time period to determine, just as we must under ourfirst inquiry, whether suppression would serve the interest protected by the Fourth Am endment’s proscription against unreasonable seizures. Id. Third, “and ‘particularly’ significant,” we examine the purposes and flagrancy of the offi cial misconduct. Id. (quoting Brown , 422 U.S. at 604). This factor favors exclusion “only when th e police misconduct is most in need of deterrence—that is, when i t is purposeful or flagrant.” Id. at 2063. Where the district court fails to employ the Brown factors
26and ask whether the taint of a prior illegality has been purged , but the record is adequately developed, we may undertake our own de novo review of these factors. Melendez-Garcia , 28 F.3d at 1054; see also supra n.10.
B. Recall the time line in this case. Local law enforcement seize d Defendant’s home around 7:00 a.m. Defendant spent the next two and a half hours at the police station speaking with Investigator Cooke and others. About 9:3 0 a.m., Defendant signed a limited consent to search form outside his home author izing Investigator Cooke to enter the home and retrieve Candice’s medication. Coo ke completed his search of Defendant’s home around 10:00 a.m. By 11:30 a.m. Coo ke possessed sufficient knowledge to procure a search warrant. He knew Defe ndant was a convicted felon and had ammunition in his bedroom closet. Cook e did not seek a search warrant, however, until the early evening hours. 11 The only event of sufficient note during the period between the establishment of probable cause that morning and the process of procu ring a search warrant that even ing was Candice’s autopsy which began at 1:30 p.m. and concluded around 3:30 p.m. A federal

11 Here we cannot help but note the affidavit in support of the search warrant represented that “Mr. Shrum and possibly others still have acce ss to the residence and could remove the ammunition and other evidence if it is notlocated and removed immediately. If the search warrant is not executed at night th ere is the possibility that evidence of a crime could be removed or destroyed.” This representation, of course, was simply not true but rather verifiably false and is indicative of the shoddy course of the investigation into Candice’s death. 27magistrate judge issued the warrant at 10:00 p.m. Three federa l agents together with Investigator Cooke and another officer executed the warrant beg inning at 11:18 p.m. or twelve hours after probable cause arose. Their search concl uded at 1:20 a.m.
In Strieff , the Supreme Court observed that its “precedents have declinedto find that [the temporal proximity] factor favors attenuation un less ‘substantial time’ elapses between an unlawful act and when the evidence is obtain ed.” Strieff , 136 S. Ct. at 2062 (quoting Kaupp v. Texas , 538 U.S. 626, 633 (2003) (per curiam)). The longer the time lapse between the initial illegality and the ac quisition of the challenged evidence, especially where the evidence is verbal, t he more likely such evidence has been purged of the illegality’s primary taint, i.e. , has become attenuated. 12 Wong Sun is the best example. There the Supreme Court held that where the defendant had been arraigned and released on his own recognizance and then voluntarily returned several days laterto make an incriminating statement, the

12 In United States v. Ceccolini , 435 U.S. 268, 276–77 (1978), the Supreme Court cogently reasoned that attenuation analysis must account for the difference between verbal and physical evidence: Witnesses are not like guns or documents which remain hidden fr om view until one turns over a sofa or opens a filing cabinet. Wi tnesses can, and often do, come forward and offer evidence entirely of their own volition. And evaluated properly, the degree of free will necessary to dissipate the taint will very likely be found more often in the case of live-witness testimony than other kinds of evidence. In so reasoning, the Court modified its observation in Wong Sun that “the policies underlying the exclusionary rule [do not] invite any logical di stinction between physical and verbal evidence.” Id. at 275 (brackets in original) (quoting Wong Sun , 371 U.S. at 486).

28connection between his unlawful arrest and his statement had “b ecome so attenuated as to dissipate the taint.” Wong Sun , 371 U.S. at 491 (quoting Nardone v. United
States , 308 U.S. 338, 341 (1939)). In other words, the defendant’s s tatement on this later date was “sufficiently an act of free will to purge the p rimary taint of the unlawful [arrest].” Id. at 486. Unlike Wong Sun , however, the facts in this cas e reveal Defendant had little time to exercise “free will” between the unlawful seizure of hi s home and his execution of the consent to search form two and a half hours la ter. See Brown , 422 U.S. at 604–05 (concluding a two hour separation between an ill egal arrest and confession without any intervening event did nothing to dissipa te the taint). And once Investigator Cooke had completed the search of Defendant’s home thirty minutes after that, the length of time taken to procure the sea rch warrant and execute it rested entirely outside Defendant’s control. While most Fou rth Amendment cases such as those addressing traffic stops or arrests involve relat ively brief time spans, Defendant’s home remained under the dominion and control of the police throughout the duration of the day long episode. Thus, the time that elap sed between the initial unlawful seizure and discovery of the incriminating evidence us ed to prosecute Defendant in itself no way rendered the connection between the two remote. While the temporal proximity between an illegal seizure and discovery of the evidence a defendant seeks to suppress is never immaterial, we conclude he re that this factor does nothing to advance the Government’s burden to prove attenu ation. See United
29States v. Ceccolini , 435 U.S. 268, 275 (1978) (“[T]he Court of Appeals was simply wrong in concluding that if the road were uninterrupted, its le ngth was immaterial.”). Turning to a consideration of intervening events, what transpir ed in the two and a half hours between the seizure of Defendant’s home and hi s consent to search is critical to our analysis. Specifically, we refer here to In vestigator Cooke’s interview with Defendant. The record first reflects Defendant’ s knowledge of his home’s seizure a few minutes after 7:00 a.m. when he called his friend Teresa from the law enforcement center and told her: “I ain’t home yet bec ause they ain’t lettin’ me go home yet.” Some two hours later, after Defendant had exp ressed the desire for an autopsy because he wanted to know why Candice died and I nvestigator Cooke had told him the coroner needed Candice’s medication, Cooke inf ormed Defendant that the police would “hold onto your house as a scene” until t he autopsy was concluded. Defendant responded “[t]hat’s fine” and “[a]nything I can do to help.” The district court found Defendant “seemingly consented” (whate ver that means) to his home’s seizure when he ag reed with Cooke during the intervi ew that the police should “hold onto” his home. The Government suggests this “agr eement” effectively purged the subsequent taint of any illegal seizure; in other wo rds, this was the first intervening event that broke the “causal chain” between the ill egal seizure and the evidence Defendant seeks to suppress. But under the circumstances presented, Defendant’s responses ha rdly establish his after-the-fact consent to his home’s unlawful seizure. Inv estigator Cooke offered
30Defendant no choice; rather Cooke was telling Defendant how it was. The record in this case gives us no reason to believe Defendant’s responses w ere anything other than “a mere submission to a claim of lawful authority.” Kaupp , 538 U.S. at 631 (quoting Royer , 460 U.S. at 497). Defendant’s statement to Teresa that “they ain’t lettin’ me go home yet,” indicate s to us that Defendant underst ood he did not have much say in the matter or much of a choice. Of course, the con cept of choice, i.e. the right to say yes or no, is inherent in the definition of co nsent. Cf. United States
v. Jones , 701 F.3d 1300, 1314 (10th Cir. 2012). The Government cannot meet its burden “by showing no more than acquiescence to a claim of lawf ul authority.” Bumper v. North Carolina , 391 U.S. 543, 548–49 (1968). The Government further tells us Defendant’s execution of the co nsent to search form authorizing Investigator Cooke to enter his home wa s the second intervening event that broke the causal chain. Again the detai ls of what transpired immediately preceding Defendant’s consent are critical. After Investigator Cooke informed Defendant he was “going to do what’s called a consent to search and I’m just going in to retrieve the medication,” Defendant refere nced the need for an attorney (a reference clearly audible on the audio tape) and hesitated before breaking down: “I wanna know what happened to her. I ain’t go t nothin’ to hide from you people. She’s my baby, she’s my everything. I know y ou have to.” Shortly thereafter Cooke sought to prompt Defendant to action w hile reassuring him: “Let’s run over to the house. Let’s get your dogs. Let’s get the medication.” Let’s
31find out “what’s going on.” A few minutes later Cooke repeatedhimself: “Let’s go get your dogs. Let’s get this medication,” all the while remin ding Defendant: “I can’t let you go in the house. I’ll just tell you I can’t let you go in the house, but if you’ll tell me where the stuff is.” Well established precedent teaches us that the question here is not only whether Defendant’s consent was voluntary but also whether his consent was “an act of free will [sufficient] to purge the primary taint of the unl awful invasion.” Kaupp , 538 U.S. at 632 (brackets in original) (quoting Wong Sun , 371 U.S. at 486). Under the second Brown factor, the Government must establish “facts or events which ensure that the consent provided was not the fruit of the illeg al seizure. The facts or events must create a discontinuity between the illegal seizu re and the consent such that the original illegality is weakened or attenuated.” Fox , 600 F.3d at 1260 (brackets, ellipses, and quotation marks omitted); see Royer , 460 U.S. at 501 (plurality) (“ Brown hold[s] that statements given during a period of illegal deten tion are inadmissible even though voluntarily given if they are the product of the illegal detention and not the result of an independent act of free will .”). Here the facts suggest Defendant’s consent to search was the di rect result of the illegal seizure of his home rather than an act of free w ill sufficient to purge its taint. By all appearances, Investigator Cooke consci ously designed the circumstances under which Defendant provided his consent to con vince him that he had no choice but to accede to the investigator’s wishes. Whena police officer
32claims authority to seize your home because your wife died unex pectedly, and tells you the coroner needs medication from the home to perform an au topsy but you cannot go inside the home to retrieve the medication, what choi ce do you have? Must you allow law enforcement to seize your home indefinitely? Defendant’s lack of choice once again is well illustrated by his statement to In vestigator Cooke, “I know you have to,” and Cooke’s subsequent reminder, “I’ll just tell you I can’t let you go in the house, but if you’ll tell me where the stuff is.” Nothing between the time of law enforcement’s illegal seizure of Defendant’s home a nd Investigator Cooke’s search of the home broke the causal chain. Because Def endant’s consent was tainted, Cooke’s search pursuant to that consent also was t ainted. And any evidence obtained as a result of an unlawful search cannot be u sed to establish probable cause for issuance of a search warrant. See Murray , 487 U.S. at 540. This leaves us to consider the purpose and flagrancy of the ill egal seizure of Defendant’s home. Because the exclusionary rule “serves to det er deliberate, reckless, or grossly negligent conduct” in addition to “recurri ng or systemic negligence,” only by considering law enforcement’s culpability may we determine the efficacy of excluding the incriminating evidence against De fendant in deterring future Fourth Amendment violations and in particular unreasonab le seizures of the home. Herring , 555 U.S. at 144. The Supreme Court has told us a court shoul d suppress evidence only if a police officer “may properly be cha rged with knowledge, that the [seizure] was unconstitutional.” Id. at 143 (quotation marks omitted). “The
33pertinent analysis of deterre nce and culpability is objective, not an inquiry into the subjective awareness” of the officer. Id. at 145 (quotation marks omitted). We ask whether a “reasonably well trained officer would have known” th e seizure of Defendant’s home was unlawful under the totality of the circums tances. Id. (quotation marks omitted). For reasons we explained in Part III of our opinion, we have no difficulty concluding that a reasonably well trained officer would have un derstood the seizure of Defendant’s home under the circumstances presented was contr ary to the Fourth Amendment. At the suppression hearing, the only explanation Investigator Cooke gave to justify the warrantless seizure of Defendant’s home fol lowing Candice’s demise was that it was not a “normal death. . . . [S]o securing anything that may have given us information into that was the reason for the scene bei ng held.” But as the astute reader well knows by now, Investigator Cooke’s justifica tion falls woefully short of what the Fourth Amendment requires to justify a warran tless seizure of a home. Absent consent, the Fourth Amendment requires probable c ause and exigent circumstances. See McArthur , 531 U.S. at 333–334. Neither is it any use to say the ATF agents who were primarily responsible for obtaining and exe cuting the search warrant were blameless and acted in good faith. Otherwise a po lice officer could illegally seize a home, obtain a tainted consent to search, andthen, equipped with incriminating evidence, rely on colleagues ignorant of the circ umstances used to justify the search warrant to obtain the same. Such an approac h would do little to
34deter unlawful seizures. See Herring , 555 U.S. at 140, 146. * * * To recap: Law enforcement unreasonably seized Defendant’s home in violation of the Fourth Amendment. Immediately thereafter, Investigator Coo ke interviewed Defendant for over two hours at the police station. Defendant subsequently signed a consent to search form permitting Cooke to search his home. But given the undisputed record facts, Defendant’s consent was not an act of free will sufficient to purge the primary taint of the illegal seizure. Rather, his consent was “come at by exploitation” of such seizure. Wong Sun , 371 U.S. at 488. Consequently, Cooke unlawfully searched Defendant’s home and witnessed ammunition i n the home’s bedroom closet. Probable cause, tainted from the unlawful sear ch, arose when Cooke connected Defendant’s status as a convicted felon with the ammu nition. Cooke requested federal agents to procure a search warrant and a neutral magistrate judge unknowingly issued a tainted warrant. Law enforcement executedthe tainted warrant and discovered the incriminating evidence Defendant now seeks t o suppress. Necessarily, this evidence too was tainted. While the causal c hain is relatively long, nowhere along the links of the chain were the “fruits” of the u nlawful seizure of Defendant’s home purged of their primary taint. Accordingly, t he district court’s denial of Defendant’s motion to suppress is REVERSED. This cau se is REMANDED for further proceedings consistent with this opinion.

35United States v. Shrum , No. 17-3059 EID , J., concurring in part and dissenting in part.

I agree with the majority that the seizure of Defendant’s home was unreasonable. The Fourth Amendment allows for “a temporary seizure [that is] supported by probable cause and . . . designed to prevent the loss of evidence while the police diligently obtai[n] a warrant in a reasonable period of time.” Illinois v. McArthur , 531 U.S. 326, 334 (2001). Here, as we conclude today, the seizure was none of th ose things. I disagree, however, with the majority’s decisi on to go on to determine whe ther the attenuation and independent source exceptions to the exclusionary rule apply (ultimately deciding that they do not), rather than remandingthe case for such a determination. I come to this conclusion for three reasons.
First, although the district cour t made some passing referencesto Defendant’s consent to the search, it did not consider whether his consent constituted a break in the causal chain under the attenuatio n doctrine because it did not need to under its understanding of the case – name ly, that the initial seizure of the home was reasonable (an understanding we find erroneous today). Nor did the distri ct court find it necessary to consider the independent source doctrine. It is the general practice of this court to remand for determination of such issues, see, e.g. , United States v. Carter , 360 F.3d 1235, 1243 (10th Cir. 2004) (concluding that “the district cour t is better able to address” whether defendant’s consent was the product of the preceding il legal search and remanding for such a determinatio n), and indeed the Supreme Court did so, after it2 declined to recognize a “crime scene exception” to the warrant requirement. Flippo v. West Virginia , 528 U.S. 11, 15 (1999) (per curiam) (remanding for consideration, inter alia, of whether defendant impliedly consented to the search); Maj. Op. at 17 (citing Flippo ). I see no reason to depart from th is general practice in thi s case. Thus, while I do not question the court’s authority to decide the issues here, Iwould not exercise our discretion to do so in this case.
Second, the issues of attenuation and independent source receiv ed virtually no attention in the briefing befo re this court. And significantly , to the extent they did receive attention, Defendant urg ed this court to remand for the ir determination. See, e.g. , Aplt. Br. at 35 (arguing that “[t] he district court should deci de, in the first instance, whether Mr. Shrum’s consent purgedthe taint of the unconstitutional seizure”); id. at 42 (“This court should also remand fo r an additional determinationon the independentsource doctrine”). 1 The lack of adequate briefing on these issues further convinc es me that they are best left to a remand.
Finally, the majority interprets and applies Utah v. Strieff , ___ U.S. ___, 136 S. Ct. 2056, 2061 (2016), the Court’s m ost recent pronouncement on thedoctrines of attenuation, independent source , and inevitable discovery – three exceptions to the

1 Defendant also argues that the district court erroneously concluded that he had abandoned his involuntary-consent argument, and asks this court to remand for the district court to adequately address the voluntariness of consent issue. Aplt. Br. at 37. The majority does not address th e abandonment issue, and instead finds that Defendant’s consent was involuntary without the benefit of adequate consideration of this issue by the district court. Maj. Op. at 31. I agree with Defendant that the district court erred in finding voluntariness abandoned , and would remand that issue aswell.3 exclusionary rule that “involvethe causal relationship betweenthe unconstitutional act and the discovery of evidence.”The majority opinion in this c ase marks the first time in a published opinion this court has interpreted and applied Strieff . In my view, the better course of action would be to explore the parameters of Strieff in a case in which there is a district court decision on the matter as well as adequate brief ing before this court.
For these reasons, I would remand this case to the district court to consider the issues of attenuation and independent source in the first instance. Accordingly, I dissent from that portion of the majority opinion declining to remand t he case.
