    OPINION OF THE COURT
    _______________
    JORDAN, Circuit Judge.
    Troy Alexander appeals the denial of his motion to
    suppress evidence against him in this drug trafficking case. As
    a general principle, evidence unlawfully obtained cannot be
    used in court. But the suppression of evidence under that
    exclusionary rule has exceptions, and two of them are
    implicated here. Namely, if the evidence in question would
    inevitably have been discovered anyway, or if a late but lawful
    search warrant was issued, suppression may not be warranted.
    The purpose of the exclusionary rule is to deter police
    misconduct that violates the Fourth Amendment. That
    deterrence, however, comes at the cost of keeping relevant
    evidence out of the fact-finding process, and that is a bad
    2
    bargain when the evidence would have come to light through
    other, lawful means.
    The police entered the homes of both Alexander and his
    girlfriend, without search warrants. In law enforcement
    parlance, the officers at each location conducted a “hit-and-
    hold;” that is, they entered and secured the premises before
    getting a warrant, a tactic sometimes used to respond to
    emergency circumstances. Once inside, and having secured
    the premises, the officers at Alexander’s home waited to
    conduct a search until a warrant for that house was issued.
    Those who entered Alexander’s girlfriend’s home likewise
    secured the premises and were in the process of applying for a
    warrant, which was all but certain to issue, when they received
    what they understood as consent to a search. Because the
    government has shown that the evidence from both locations
    would have been discovered in any event, we need not consider
    the lawfulness of the hit-and-holds or subsequent searches, and
    we will affirm the District Court’s denial of the motion to
    suppress.
    I.    BACKGROUND1
    A.     The Criminal Investigation
    In October 2018, DEA agents met with a confidential
    informant who told them that Alexander was involved in drug
    trafficking and, more specifically, had access to multiple
    kilograms of cocaine, had sold cocaine to him in the past, and
    1
    The following account is drawn from the record
    created at the suppression hearing, including the District
    Court’s findings of fact.
    3
    was known to possess firearms. The informant provided the
    address of Alexander’s home in downtown Wilmington – 728
    East Sixth Street (the “Residence”) – where Alexander lived
    with his sister. He also informed the agents that Alexander’s
    girlfriend lived in the same vicinity. Some of the details about
    Alexander were corroborated by Paul Lawrence, an officer
    with the Newark, Delaware, Police Department who was
    assigned to work with the DEA.2
    A task force created by the DEA then arranged for the
    confidential informant to make a controlled purchase of
    cocaine from Alexander on November 19, 2018.3 Before the
    purchase, there were three phone calls between the informant
    and Alexander. During the first call, which agents were able
    to record, the informant asked to buy cocaine, and Alexander
    said that he would be ready in an hour. Alexander told the
    informant to meet him then on the 700 block of East 6th Street
    in Wilmington. The second call was made by Alexander to the
    informant, who answered it outside the presence of task force
    officers, so it was not recorded. On the third call, the informant
    2
    Among other things, Officer Lawrence corroborated
    the address of the Residence and Alexander’s phone number,
    the latter of which was subsequently used to set up a controlled
    drug buy with the confidential informant.
    3
    The task force “consisted of agents from the DEA,
    agents from the U.S. Department of Homeland Security, and
    Delaware police officers[.]” (App. at 414.) We variously refer
    to the task force members as “officers,” “agents,” or
    “members.”
    4
    called Alexander, but the officers were only able to record the
    informant’s end of the conversation.4
    On the day of the sale, the officers outfitted the
    informant with an audio and video recording device and
    provided him with $900 to exchange for the drugs. They then
    set up a surveillance perimeter. Approximately twenty minutes
    later, agents observed Alexander leave the house at 722 East
    7th Street, one block from the Residence, and walk to meet the
    informant. The officers later learned that this second house
    was where Alexander’s girlfriend, Venus Nelson, lived, and
    that Alexander used it as a stash house (the “Stash House”) for
    his drug trafficking business.5 The task force officers on the
    scene witnessed Alexander give the informant what later tested
    to be almost 115 grams of cocaine in exchange for the $900.
    Unbeknownst to the task force, the informant had placed the
    recording device in his pocket during the sale, so no video was
    captured. The device did, however, record the conversation,
    and, during the exchange, Alexander told the informant that the
    price of the cocaine was $2,300, so the informant still owed
    him $1,400.
    Nine days later, on November 28, the officers instructed
    the informant to arrange another purchase of cocaine. He did
    4
    The record is devoid of any information about what
    was said during the second and third calls.
    5
    The confidential informant had not previously
    identified the Stash House by address, but as noted earlier, he
    had informed the officers that Alexander’s girlfriend lived near
    the Residence.
    5
    so, and, during a recorded phone call, Alexander explained that
    he was in Philadelphia and would not return to Delaware until
    7:00 that evening.6 Anticipating Alexander’s return, the task
    force set up surveillance outside both the Residence and the
    Stash House.
    The officers on surveillance duty made several
    observations between 6:30 and 8:30 that night. They first saw
    Alexander arrive at the Residence, park his car on the side of
    the road, and carry into the house a large, heavy, white bag.
    About two minutes later, he emerged with a smaller white bag
    that he appeared to struggle to carry. He took that bag to the
    Stash House and entered using his own key. After a few
    minutes, he returned to the Residence empty-handed. At that
    point, following DEA instructions, the confidential informant
    called Alexander to offer the money still owed on the first
    transaction. Alexander responded that he would get it from the
    informant the next day. He also told the informant that he
    didn’t have “anything” for him but “might be ready
    tomorrow.” (App. at 61, 417.) Alexander then went to the
    Stash House again and came out carrying a large black trash
    bag, which he brought back to the Residence.
    6
    According to the District Court, the task force believed
    that Alexander’s trip to Philadelphia was significant for two
    reasons. First, the informant had previously told agents that
    Alexander procured his drugs from Philadelphia. Second, the
    DEA and local police were generally aware that Philadelphia
    was a “source city for drugs sold in northern Delaware.” (App.
    at 415-16.)
    6
    Events took an unexpected turn about an hour later,
    when a Kia Optima pulled up to the Residence and the
    passenger went inside. The passenger left the Residence at
    8:13 p.m., carrying what appeared to be the same black trash
    bag that Alexander had brought from the Stash House. The
    Kia drove off, and officers in unmarked cars followed. At 8:21,
    when the Kia was far enough away to be out of sight of anyone
    at the Residence, the officers attempted to effect a traffic stop.
    It did not go as planned. “The Kia came to a momentary stop,
    but then successfully fled the scene, smashing into several of
    the officers’ vehicles in the process.” (App. at 418.)
    B.     The Warrant Application
    Meanwhile, throughout the evening, officers at the
    scene had been providing contemporaneous updates to Officer
    Lawrence, who was at the DEA’s office in New Castle,
    Delaware. He began drafting an affidavit in support of search
    warrants for the Residence and the Stash House, based on
    “Alexander’s movements [between the two], the monitored
    calls with the [confidential informant], the … controlled drug
    buy, and the task force officers’ general knowledge that
    Philadelphia is a source of supply for drugs sold in
    Wilmington[.]” (App. at 417.) At 8:20 p.m. – just after the
    Kia had driven away from the Residence – he emailed a draft
    affidavit to a federal prosecutor. That draft was later
    supplemented to include a description of the car chase. The
    affidavit also stated that “agents have already entered the
    residence based on exigent circumstances and have detained its
    occupants,” but no further details were provided. (App. at 63.)
    7
    C.     The Hit-and-Holds
    After the Kia escaped, things happened fast. The
    officers watching the Residence saw Alexander leave it while
    speaking on his cellphone and then drive off in his car. The
    surveillance team believed he “may have been tipped off by the
    Kia occupants,” so at around 8:30 p.m., they simultaneously
    entered both the Residence and the Stash House, although they
    still had no warrants. (App. at 419.) An agent on the scene,
    Anthony Salvemini,7 later explained their thought process:
    “We didn’t know where [Alexander] was. … [T]here had been
    a car chase, so it was somewhat of an urgent scenario.” (App.
    at 299.) The officers’ primary concern, he said, was preventing
    the destruction of evidence in the houses. They thus “entered
    both houses, performed protective sweeps, and handcuffed the
    occupants to [en]sure the safety of law enforcement and
    prevent the destruction of evidence while search warrants were
    being obtained.” (App. at 419.)
    1.     The Stash House
    Up to eight task force officers forcibly entered the Stash
    House wearing ballistic vests and with guns drawn. Within a
    few seconds, Ms. Nelson, Alexander’s girlfriend, appeared at
    the top of the stairs. The officers instructed her to come down,
    which she did, and they put her in handcuffs and told her to
    remain in the living room. According to Agent Salvemini,
    Nelson appeared “naturally surprised” but eventually “calmed
    down.” (App. at 305, 419-20.)
    7
    Salvemini is an agent with the DHS who specializes in
    drug investigations and works in partnership with the DEA.
    8
    Within five minutes of their entry, they had checked all
    three floors of the Stash House, checking for other occupants.
    Agent Salvemini then introduced himself to Nelson, who was
    still in handcuffs. He told her that they “were in the process of
    applying for a search warrant[.]” (App. at 420.) When he
    asked about evidence of drug dealing, her response was only
    that “there were some firearms upstairs that belonged to her,
    but they were legal[.]” (App. at 420.)
    While they were talking, an officer approached Agent
    Salvemini and whispered that he had seen a large amount of
    cocaine and drug paraphernalia in plain view in the basement.
    Agent Salvemini then told Nelson that, although she had a right
    to refuse, he did not think it would be a problem to get a
    warrant, and “it would save everybody a lot of time” if she
    consented to a search. (App. at 306, 420.) Nelson replied, “go
    ahead and search the house.” (App. at 306, 420.) With that,
    the search began, and no warrant application was submitted for
    the Stash House. Officers recovered “powder and crack
    cocaine, cutting agent, two scales, and a kilogram press with
    molds.” (App. at 423.) They also seized “two handguns and
    an extended magazine[.]” (App. at 423.)
    2.     The Residence
    Simultaneous with the hit-and-hold at the Stash House,
    another group of officers entered the Residence. There, they
    encountered Alexander’s sister and another person, both of
    whom they handcuffed. After a safety-sweep of the premises,
    the officers waited inside the Residence for close to three
    hours, until a magistrate judge signed a search warrant. During
    the execution of that warrant, officers seized about $67,000 in
    9
    cash, two handguns, 285 rounds of ammunition, a digital scale,
    a Rolex watch, two diamond chains, and documents that listed
    the residence as Alexander’s address.
    D.     The Arrest
    Rewinding to approximately 8:48 p.m. – not long after
    the hit-and-holds were executed – Alexander approached the
    Stash House on foot. Four officers were stationed in front, and
    Alexander told them, “I heard you guys were looking for me.
    I don’t want my sister or anyone else to get in trouble. All that
    stuff in there is mine.” (App. at 287, 423-24.) Officers arrested
    him and placed him in a DEA car, where Agent Salvemini read
    him his Miranda rights.
    At around 9:00 p.m., officers brought Alexander to a
    DEA office where he was placed in a holding cell. Officer
    Lawrence, who was told that Alexander had already been read
    his Miranda rights, introduced himself as the primary case
    agent. Alexander responded: “I don’t want my girl to get in
    any trouble … anything in there is mine.” (App. at 425.) A
    little later, Alexander asked to speak to Officer Lawrence
    again, and he gave a recorded interview taking responsibility
    for and describing the details of his drug-dealing operations.
    Before he did that, Alexander was advised of his Miranda
    rights for a second time, which he acknowledged. He was
    released from custody that evening.
    E.     The Motion to Suppress
    A few months later, a federal grand jury returned a four-
    count indictment that charged Alexander with possession with
    intent to distribute twenty-eight grams or more of cocaine base,
    10
    in violation of 
    21 U.S.C. § 841
    (a)(1) and (b)(1)(B); possession
    with intent to distribute cocaine, in violation of 
    21 U.S.C. § 841
    (a)(1) and (b)(1)(C); possession of a firearm in
    furtherance of a drug trafficking crime, in violation of 
    18 U.S.C. § 924
    (c)(1)(A)(i); and possession of a firearm by a
    prohibited person, in violation of 
    18 U.S.C. §§ 922
    (g)(1) and
    924(a)(2).
    Alexander eventually moved to suppress all the
    evidence seized from the Stash House and the Residence. He
    first argued that the searches violated the Fourth Amendment,
    because no valid consent was given to search the Stash House,
    and because the warrant for the Residence was based on mere
    speculation and false statements.8 Later, in a supplemental
    filing, Alexander also moved to suppress “all custodial
    incriminating statements made by him to law enforcement” as
    obtained in violation of the Fifth and Sixth Amendments.9
    (App. at 73.)
    8
    In particular, Alexander claimed that Officer
    Lawrence’s affidavit falsely asserted that the task force
    possessed “numerous monitored and recorded telephone
    conversations” between the informant and Alexander, when in
    fact only one recording captured both sides of a conversation.
    (App. at 101.) He also challenged the affidavit’s representation
    that the officers possessed a video recording of the drug sale
    when, in fact, the video portion of the recording only captured
    the inside of the informant’s pocket.
    9
    For ease of reference, we refer to the original and
    supplemental filings as a single motion to suppress.
    11
    The District Court held an evidentiary hearing on the
    motion, at which Officer Lawrence testified to the warrant’s
    veracity, stating that he had drafted the substance of the
    affidavit prior to the officers’ warrantless entry and that he had
    intended to file the same affidavit in support of warrants for
    both the Stash House and the Residence. He also confirmed
    that the affidavit was based on calls between the confidential
    informant and Alexander, a recording of a controlled buy
    between those two, and the officers’ surveillance of the Stash
    House and the Residence.
    The government also had DEA agent Antonio Tiberi
    testify. He was standing outside the Stash House when
    Alexander “walk[ed] hastily” toward it and claimed ownership
    of “[a]ll that stuff in there.” (App. at 287.) The government
    next called Agent Salvemini to the stand. He testified that both
    houses were entered “[a]s close to simultaneous[ly] as
    possible,” and he gave the specifics of the hit-and-hold at the
    Stash House. (App. at 298.)
    Defense counsel called two witnesses at the suppression
    hearing: Nelson and Alexander.          Nelson testified that
    Alexander stayed with her in her home approximately four
    days a week. According to Nelson, the officers conducted a
    search of her home before asking her for consent, and, when
    she eventually was asked for consent, she was not informed of
    her right to refuse. On cross-examination, she testified about
    her relationship with Alexander, agreeing that “if he needed
    anything, [she] would be right there[.]” (App. at 336.)
    Alexander testified about his dealings with the
    government’s informant. He stated that the two of them never
    discussed a drug transaction on the day Alexander was in
    12
    Philadelphia. He also claimed that the bag the officers saw him
    carrying between the Residence and the Stash House contained
    jewelry, not drugs. Finally, he testified he only admitted that
    the evidence seized from the Stash House was his because an
    officer told him Nelson was “going down for the stuff found in
    the house[.]” (App. at 353.)
    F.     The District Court’s Denial of the Motion to
    Suppress
    At the conclusion of the hearing, the District Court
    denied the motion to suppress. Among other things, the Court
    found that, while Officer Lawrence’s affidavit may not have
    been perfect, Alexander had overstated its inaccuracies. There
    were, the Court said, “no misstatements … [and] no omissions”
    in it. (App. at 379.)
    In a subsequent written opinion, the District Court
    elaborated on its earlier in-court rulings. It concluded that,
    prior to the hit-and-holds, there was probable cause to believe
    Alexander had cocaine and drug-dealing paraphernalia in the
    Residence and the Stash House. It further found that “the
    officers had reason to believe that Alexander and anyone in the
    [R]esidence or Nelson’s home had been tipped off about the
    officers’ failed attempt to stop the Kia and thus the officers had
    reason to believe that any cocaine or related evidence of drug
    dealing in the [R]esidence or Nelson’s home would be
    imminently destroyed.” (App. at 430.) Thus, the Court said,
    there were exigent circumstances justifying the officers to
    enter without a warrant.
    The Court determined that the search of the Residence
    was valid because a warrant was properly issued. And, as for
    13
    the validity of the warrantless search of the Stash House, that
    was upheld as being based on Nelson’s consent. The Court
    observed that, “[a]lthough the task force had already entered
    the house, detained Nelson, and performed a protective sweep,
    there is no indication that those actions put undue pressure on
    Nelson.” (App. at 433.) It credited Agent Salvemini’s
    testimony over Nelson’s, ultimately holding that her consent
    and the search were valid. It also rejected Alexander’s attempt
    to suppress his incriminating statements on the basis of
    supposed Fifth and Sixth Amendment violations.
    Alexander ultimately pled guilty to Counts One, Two,
    and Four of the indictment, and the parties stipulated to a
    sentence of 132 months, which the Court entered. The plea
    agreement expressly preserved Alexander’s right to appeal the
    denial of the motion to suppress, which he timely did.
    II.   DISCUSSION10
    On appeal, Alexander continues to challenge the
    constitutionality of the warrantless entry into the Residence
    and the Stash House and argues that the results of the
    subsequent searches must be suppressed. While he vigorously
    10
    The District Court had jurisdiction under 
    18 U.S.C. § 3231
    . We have appellate jurisdiction pursuant to 
    28 U.S.C. § 1291
    . We review “the District Court’s denial of a motion to
    suppress for clear error as to the underlying factual findings
    and exercise[] plenary review of the District Court’s
    application of the law to those facts.” United States v. Perez,
    
    280 F.3d 318
    , 336 (3d Cir. 2002). In the context of warrantless
    searches, we review de novo the determination of probable
    cause. Ornelas v. United States, 
    517 U.S. 690
    , 691 (1996).
    14
    contests the justification for the officers’ actions, as well as the
    validity of Nelson’s consent to search the Stash House, we do
    not need to reach those issues because we choose to affirm the
    District Court on alternative bases. Watters v. Bd. of Sch. Dirs.,
    
    975 F.3d 406
    , 412-13 (3d Cir. 2020). We do so because, even
    if we were to agree with Alexander that the circumstances were
    not truly exigent or that Nelson did not provide valid consent,
    the independent source doctrine and the doctrine of inevitable
    discovery nevertheless support admission of the evidence from
    the searches of the Residence and the Stash House,
    respectively.
    As more fully described herein, the independent source
    doctrine covers the evidence found in the Residence, because
    the officers pursued and ultimately obtained a valid search
    warrant based solely on information gathered prior to their
    entry. And the search of the Stash House is similarly shielded
    under the inevitable discovery doctrine, because the officers
    were far enough along in the warrant application process that,
    had they not received what they believed to be consent, a
    warrant would have issued and the evidence would have been
    found. The District Court’s denial of Alexander’s motion to
    suppress was therefore correct.11
    11
    Alexander does not now advance any arguments
    under the Fifth and Sixth Amendments. He instead asserts
    more generally that any statements he made following the task
    force officers’ search and seizure must be suppressed. As
    discussed herein, to the extent he is making an argument under
    the Fourth Amendment’s fruit-of-the-poisonous-tree doctrine,
    which generally requires suppression of evidence that is
    derived from an illegal search or seizure, it similarly fails. See
    Utah v. Strieff, 
    579 U.S. 232
    , 237-38 (2016) (recognizing the
    15
    A.     Evidence Obtained from the Residence, and
    the Independent Source Doctrine
    We first consider the evidence obtained at the
    Residence. Our analysis addresses two questions; first,
    whether there was a substantial basis to say there was probable
    cause to support the warrant that was prepared before but
    issued after the entry there, and second, whether the warrant
    supported the subsequent search notwithstanding the
    warrantless entry. The answer to both is yes. There was
    probable cause to support a search, based on an objective
    likelihood of criminal activity going on at the Residence. And
    the later-issued warrant justified the warrantless entry because
    the warrant was based only on information obtained before task
    force members ever entered the home. It therefore established
    a lawful, independent source for obtaining the evidence found
    there. So, even if exigent circumstances did not justify
    entering the Residence without a warrant (an issue we do not
    address), the independent source doctrine allows denial of the
    motion to suppress as to that evidence.
    1.     The Warrant to Search the Residence
    was Supported by a Sufficient Showing of
    Probable Cause
    To obtain a search warrant, the government must
    present probable cause that evidence of criminal activity will
    be found in the place to be searched. See Smith v. Ohio, 
    494 U.S. 541
    , 542 (1990) (“[T]he Fourth Amendment … proscribes
    independent source and inevitable discovery doctrines as
    exceptions to that doctrine).
    16
    – except in certain well-defined circumstances – the search of
    [a] property unless accomplished pursuant to judicial warrant
    issued upon probable cause.”). That standard requires that
    there be “a fair probability that contraband or evidence of a
    crime will be found in a particular place.” Illinois v. Gates,
    
    462 U.S. 213
    , 238 (1983). Probable cause “is a fluid concept
    – turning on the assessment of probabilities in particular factual
    contexts – not readily, or even usefully, reduced to a neat set
    of legal rules.” 
    Id. at 232
    . Determining whether probable
    cause is met depends on “the basis and strength of an officer[’s]
    … belief … that an article subject to seizure can be found at a
    particular location – in short, whether criminal activity is
    afoot.” United States v. Vasquez-Algarin, 
    821 F.3d 467
    , 476
    (3d Cir. 2016).
    Here, however, we are not being asked to judge a
    probable cause showing in the first instance. Rather, we must
    consider the propriety of the probable cause finding made by
    the magistrate judge who issued the warrant. Accordingly, we
    need not “determine whether probable cause actually existed,
    but only whether there was a substantial basis for finding
    probable cause.” United States v. Hodge, 
    246 F.3d 301
    , 305
    (3d Cir. 2001) (internal quotation marks omitted) (quoting
    United States v. Jones, 
    994 F.2d 1051
    , 1054 (3d Cir. 1993)).
    We answer that question by looking at the information
    submitted to the magistrate judge in Officer Lawrence’s
    affidavit. 
    Id.
    Doing so, it is easy to conclude that a substantial basis
    existed for the finding of probable cause. Alexander argues
    that the failure of the informant to record video (as opposed to
    just audio) of the controlled purchase, when considered along
    with Alexander’s statement to the informant that he “did not
    17
    have ‘anything’” for the informant (App. at 61), shows that any
    evidence of drug dealing is insufficiently linked to the
    Residence, precluding a finding of probable cause. To the
    contrary, however, there were ample reasons for the magistrate
    judge’s determination that evidence of drug trafficking was
    likely to be found in the Residence. Those reasons include the
    informant’s statements about Alexander’s drug dealing, the
    controlled purchase in the vicinity of the Residence,
    Alexander’s return to the Residence from Philadelphia where
    officers believed he had received new drug supplies, the very
    fact that Alexander lived there and was seen going back and
    forth between the Residence and the Stash House with heavy
    bags in hand, and the Kia’s destructive flight from police after
    its passenger left the Residence with one such bag. Those facts
    provided more than adequate support for a finding of probable
    cause. See United States v. Stearn, 
    597 F.3d 540
    , 558 (3d Cir.
    2010) (“When the crime under investigation is drug
    distribution, a magistrate may find probable cause to search the
    target’s residence even without direct evidence that contraband
    will be found there.”).
    2.     The Independent       Source    Doctrine
    Applies
    The more challenging question is whether the search
    warrant can serve as an independent source for the evidence
    discovered after the officers’ warrantless entry into the
    Residence, so as to cleanse the entry of any potential
    unconstitutionality. Although there are unanswered questions
    about whether hit-and-hold procedures like the ones employed
    here adequately respect our constitutional guardrails, the
    independent source doctrine is sufficient, on this record, to
    overcome the general rule that would require suppression of
    18
    the evidence obtained from the Residence if the entry or search
    were illegal.
    “[U]nder the independent source doctrine, evidence that
    was in fact discovered lawfully, and not as a direct or indirect
    result of illegal activity, is admissible.” United States v.
    Herrold, 
    962 F.2d 1131
    , 1140 (3d Cir. 1992) (emphasis
    omitted); see also Segura v. United States, 
    468 U.S. 796
    , 805
    (1984) (“[T]he exclusionary rule has no application [where]
    the Government learned of the evidence ‘from an independent
    source.’” (second alteration in original) (quoting Wong Sun v.
    United States, 
    371 U.S. 471
    , 487 (1963))). The basis for the
    doctrine is “the well-established principle that evidence is not
    to be excluded if the connection between the illegal police
    conduct and the discovery and seizure of the evidence is so
    attenuated as to dissipate the taint.” United States v. Perez, 
    280 F.3d 318
    , 338 (3d Cir. 2002) (internal quotation marks
    omitted) (quoting Segura, 
    468 U.S. at 797
    ). The Supreme
    Court in Murray v. United States advised that, when a
    potentially illegal entry is followed by an “independently
    obtained search warrant,” the evidence obtained pursuant to
    that warrant or “observed in plain view at the time of [the] prior
    illegal entry” need not be suppressed. 
    487 U.S. 533
    , 535, 537
    (1988). The Supreme Court made clear that a subsequent
    search warrant is not independently obtained if law
    enforcement decided to seek the warrant due to information
    gathered from the initial, unlawful entry, or if information
    obtained from the initial unlawful entry influenced the
    magistrate judge’s decision to issue the warrant. Id.; see also
    United States v. Stabile, 
    633 F.3d 219
    , 243-44 (3d Cir. 2011)
    (citing Herrold, 
    962 F.2d at 1140
    ).
    19
    Here, the search warrant was issued based on
    information obtained before the officers entered the building,
    and thus, under Murray, the independent source doctrine is
    applicable. In Murray, officers illegally forced their way into
    a warehouse, without a warrant, where they “observed in plain
    view numerous burlap-wrapped bales that were later found to
    contain marijuana.” Id. at 535. They left and later returned,
    after receiving a search warrant. Id. at 535-36. The warrant
    was based on information obtained prior to the illegal entry and
    did not mention that entry. Id. at 536. The Court explained
    that suppression is not appropriate for “evidence initially
    discovered during, or as a consequence of, an unlawful search,
    but later obtained independently from activities untainted by
    the initial illegality.” Id. at 537, 541-42; accord United States
    v. Huskisson, 
    926 F.3d 369
    , 374-76 (7th Cir. 2019) (collecting
    cases and “agree[ing] with several other circuits that, to
    determine whether the inclusion of tainted evidence in the
    warrant application affected the magistrate’s decision to issue
    a search warrant, we evaluate whether the warrant application
    contained sufficient evidence of probable cause without the
    references to tainted evidence, even when that tainted evidence
    was recovered from an illegal entry into a home”).
    That standard is met here. The officers’ decision to seek
    a warrant was, as in Murray, not prompted by anything
    witnessed during their warrantless entry. Murray, 
    487 U.S. at 542
    . And the information obtained during that warrantless
    entry was not included in the affidavit, which was premised
    solely on lawfully obtained, pre-search evidence.             
    Id.
    Alexander’s only rebuttal to the force of that reasoning is to
    repeat his earlier argument that “law enforcement lacked
    probable cause to believe contraband would be found in [his]
    residence.” (Reply Br. at 15.) But, as already discussed, the
    20
    search warrant was supported by probable cause and was valid.
    Because the independent source doctrine controls, Alexander
    is not entitled to have the evidence obtained from the
    Residence suppressed.
    B.     Evidence Obtained from the Stash House, and
    the Inevitable Discovery Doctrine
    Analysis of the government’s actions at the Stash House
    is more complicated because the officers never actually applied
    for a warrant and instead conducted a full search of the
    property after getting what they took to be consent from
    Nelson. Even so, the doctrine of inevitable discovery applies
    to bar exclusion of the evidence seized there. It is undisputed
    that the investigating officers had substantially progressed in
    their application for a warrant to search the Stash House. That
    application, had it been completed, was sufficient to
    demonstrate probable cause.
    1.     Probable Cause Existed to Search the
    Stash House
    Alexander disputes that there was probable cause to
    believe evidence of drug dealing was in the Stash House.12 He
    12
    In the District Court, the government contested
    Alexander’s standing to challenge the search of the Stash
    House. The Court effectively rejected that argument, finding
    that Alexander stayed overnight at the Stash House at least four
    times a week, had a key to the Stash House, and could enter it
    at will. See Rakas v. Illinois, 
    439 U.S. 128
    , 143-44 (1978)
    (holding that Fourth Amendment protections turn on the
    legitimate expectation of privacy). Nevertheless, the Court
    21
    contends that the informant did not direct the task force officers
    there and that their surveillance did not sufficiently show any
    illegality at that location. Again, the record weighs against
    him.
    Officer Lawrence’s affidavit showed the following:
    Alexander exited the Stash House immediately before selling
    cocaine to the informant; Alexander traveled to Philadelphia,
    which is where the informant said Alexander procured drugs;
    Alexander told the informant he “might be ready” the next day
    (App. at 61); Alexander carried heavy bags in multiple trips
    between the Stash House and the Residence; a visitor left the
    Residence with a bag that appeared to originate from the Stash
    House; and that visitor entered the Kia and evaded the police
    in a car chase shortly thereafter. Those facts are enough to
    support the conclusion that there was probable cause to believe
    the Stash House contained evidence of illegal drug trafficking.
    See Stearn, 
    597 F.3d at 556-58
     (holding that the magistrate
    judge properly credited an informant’s tip in granting a search
    warrant because the tip was circumstantially corroborated by
    surveillance observations of the property in question showing
    invited the government to provide further briefing on the issue,
    which the government did not do, nor has it pursued the issue
    on appeal. We take the government’s silence as a concession
    that Alexander has standing. See United States v. Stearn, 
    597 F.3d 540
    , 551 n.11 (3d Cir. 2010) (“Fourth Amendment
    ‘standing’ is one element of a Fourth Amendment claim, and
    does not implicate federal jurisdiction.           Consequently,
    ‘standing’ can be conceded by the government, and it is also
    subject to the ordinary rule that an argument not raised in the
    district court is waived on appeal.” (internal citation omitted)).
    22
    that it was the “focal point of [certain co-conspirators’]
    movements among properties”).
    2.     The Inevitable     Discovery    Doctrine
    Applies
    The question then becomes whether a search warrant
    would have inevitably issued if the warrant application had
    been submitted. We conclude that, because there was probable
    cause to search the Stash House, and because an affidavit was
    fully drafted and ready to submit at the time of the hit-and-
    hold, a search warrant was surely forthcoming and discovery
    of the evidence inside the home was inevitable. In so holding,
    we emphasize that there was probable cause for a warrant and
    that the government had taken nearly all of the steps necessary
    to acquire a warrant when it received what it perceived to be
    Nelson’s consent.
    The key question under the inevitable discovery
    doctrine is whether “the Government has shown by a
    preponderance of the evidence that routine police procedures
    inevitably would have led to the discovered” evidence. Stabile,
    
    633 F.3d at 245
    . Our focus is on “historical facts capable of
    ready verification, and not speculation.” 
    Id. at 246
     (quoting
    United States v. Vasquez De Reyes, 
    149 F.3d 192
    , 195 (3d Cir.
    1998). Decisions from our sister circuits have looked to two
    factors that we agree are most salient here: the likelihood of a
    warrant issuing, and how far into the application process the
    government was when its pursuit of a warrant was cut off. See,
    e.g., United States v. Hughes, 
    640 F.3d 428
    , 440 (1st Cir. 2011)
    (“The troopers had support staff on stand-by, ready to apply for
    a warrant, and the warrant issued the next day. That was
    sufficient for the inevitable discovery doctrine to take
    23
    hold[.]”); United States v. Are, 
    590 F.3d 499
    , 507 (7th Cir.
    2009) (“[I]t is reasonable to conclude that the officers would
    have sought a warrant to search the bedroom and, once they
    had, it is virtually certain that a warrant would have been
    issued.”); United States v. Lamas, 
    930 F.2d 1099
    , 1103 (5th
    Cir. 1991) (finding it relevant that, “at the time of the
    warrantless search, the officers had begun actively to pursue a
    warrant”).
    In this case, Officer Lawrence drafted a single affidavit
    in support of warrants to search both the Residence and the
    Stash House. Although the affidavit was only submitted in
    pursuit of a warrant for the Residence, that submission resulted
    in a warrant being issued and executed within three hours of
    the Stash House search. On this record, then, it appears
    inevitable that, if the officers had chosen to wait for a warrant,
    one would have issued and the result here would have been the
    same. Cf. Nix v. Williams, 
    467 U.S. 431
    , 444 (1984) (“If the
    prosecution can establish by a preponderance of the evidence
    that the information ultimately or inevitably would have been
    discovered by lawful means ... then the deterrence rationale has
    so little basis that the evidence should be received.”).
    Inevitability is a high threshold, but the government has
    crossed that threshold here: it consistently pursued a lawful
    means of searching the Stash House and made significant
    progress toward that end. Indeed, ordering suppression in this
    case would not further any deterrence justification. See
    Stabile, 
    633 F.3d at 246
     (“[T]he very fact that the Government
    attempted to secure state and federal search warrants at every
    step of the search indicates that there would be little deterrence
    benefit in punishing the Government.”).
    24
    Our holding here should not be read to categorically
    condone hit-and-hold procedures justified after the fact by an
    in-progress warrant application. Rather, we are guided by the
    specific facts of this case. If, for example, the task force had
    less vigorously pursued a search warrant for the Stash House,
    or if we had doubts as to whether their decision to halt that
    process was based on something other than a genuine belief
    that Nelson had consented to a search, our holding today might
    be different. Cf. United States v. Heath, 
    455 F.3d 52
    , 60 (2d
    Cir. 2006) (“[W]e conclude that illegally-obtained evidence
    will be admissible under the inevitable discovery exception to
    the exclusionary rule only where a court can find, with a high
    level of confidence, that each of the contingencies necessary to
    the legal discovery of the contested evidence would be
    resolved in the government’s favor.”). In short, the inevitable
    discovery doctrine is not an open invitation for the government
    to conduct and then justify warrantless searches. It is instead a
    narrow doctrine that the government cannot prospectively plan
    on accessing.13
    13
    That the doctrine is applicable on this record, though,
    can be seen by comparison with the decision United States v.
    Lamas, 
    930 F.2d 1099
     (5th Cir. 1991). There, the police
    entered a home based on their perception of exigent
    circumstances to secure the scene until a warrant could issue.
    
    Id. at 1100-01
    . It was a hit-and-hold, in practicality if not in
    name. See 
    id. at 1101-03
     (“[T]he officers initially entered [the
    defendant’s] house solely for the purpose of securing it until a
    warrant could be obtained.”). Although an affidavit had not
    yet been drafted, one of the officers left the scene to work on
    getting a warrant. 
    Id. at 1101, 1103
    . After the officer’s
    departure, the other officers got what they took to be consent
    from the homeowner to conduct a search. That perceived
    25
    III.   CONCLUSION
    Because a warrant for the Residence was independently
    and lawfully obtained, the evidence found there is not subject
    to suppression. Similarly, evidence from the Stash House
    would have been inevitably obtained regardless of whether
    Nelson actually gave consent, and regardless of the officers’
    warrantless entry, so the evidence found there will also not be
    suppressed. We will therefore affirm the District Court’s
    denial of Alexander’s motion to suppress.
    consent cut short the warrant process. 
    Id. at 1101-03
    .
    Nevertheless, the government was able to demonstrate that
    probable cause would have supported a warrant, and the court
    was persuaded “that the officers – absent [the defendant’s]
    consent – would have discovered the damning evidence
    pursuant to a search warrant.” 
    Id. at 1104
    ; see also United
    States v. Cunningham, 
    413 F.3d 1199
    , 1204-05 (10th Cir.
    2005) (applying the inevitable discovery doctrine where police
    “had focused their investigation on [two homes], and had
    drafted an affidavit to support a search warrant for one of these
    homes,” but stopped pursuing a warrant for the other home
    based on supposed consent).
