    OPINION
    Presiding Judge Paul J. McMurdie delivered the Court’s opinion, in which
    Judge Michael J. Brown joined. Judge Michael S. Catlett specially
    concurred.
    M c M U R D I E, Judge:
    ¶1            The State appeals from the superior court’s order suppressing
    Mitcham’s DNA profile. The State argues that developing a DNA profile
    from blood lawfully in its possession does not constitute a search under the
    Fourth Amendment. In the alternative, the State argues that, under the
    circumstances, the use of Mitcham’s DNA profile is permitted by an
    exception to the warrant requirement.
    ¶2             We agree with the State that creating a DNA profile from a
    lawfully held blood sample does not violate the Fourth Amendment. But
    here, the State’s possession was no longer lawful because the State acquired
    the blood through consent and developing a DNA profile from it exceeded
    the scope of that consent. Still, the superior court erred by suppressing
    Mitcham’s DNA profile because (1) probable cause supported his arrest
    even without the impermissible DNA match that allowed the State to obtain
    a buccal swab and develop a DNA profile; and (2) once Mitcham pled guilty
    to other felony charges, the profile was properly in the State’s possession.
    Thus, we reverse the suppression order and remand for further
    proceedings.

    STATE v. MITCHAM
    Opinion of the Court
    FACTS AND PROCEDURAL BACKGROUND
    ¶3             In February 2015, a woman was found dead in her home lying
    nude in a pool of blood. The victim had sustained several injuries, including
    a large wound on the back of her head, ligature marks around her neck, and
    several lacerations to her vagina. The police identified a strong chemical
    odor throughout the house, chemical burns on the victim, and blood smears
    near the furniture. Based on the evidence, the police concluded that the
    killer had tried to clean up the crime scene. The police collected biological
    swabs from the scene and developed an unknown male DNA profile. Police
    entered the unknown DNA profile into the federal Combined DNA Index
    System (“CODIS”). But the CODIS database returned no matches, and the
    murder went unsolved.
    ¶4             In 2018, law enforcement performed a familial DNA test on
    the unknown profile. The test identified an Arizona prison inmate as a close
    relative of the unknown profile. The police discovered the inmate had two
    brothers, one living close to the crime scene. As a result, the police began to
    surveil this brother, the defendant Ian Mitcham.
    ¶5           Coincidentally, the police were already familiar with
    Mitcham. In January 2015, they arrested Mitcham for a misdemeanor
    driving under the influence (“DUI”) offense. Also, before the familial DNA
    test, Mitcham had been charged with a felony narcotics possession offense
    in 2016 and an aggravated DUI in 2017. See State v. Mitcham, Maricopa
    County Cause No. CR2016-111513-001; State v. Mitcham, Maricopa County
    Cause No. CR2017-001717-001. Mitcham would later plead guilty to both
    crimes.
    ¶6            During the 2015 DUI arrest, Mitcham consented to have his
    blood drawn. Police read Mitcham the warning provided by the Admin Per
    Se Implied Consent form, which provided that if Mitcham agreed to the
    draw, the blood would be used “to determine alcohol concentration or drug
    content.” See Ariz. Dep’t of Trans. Form #40-5807; see also A.R.S. § 28-1385.
    The warning authorized no other blood testing, and Mitcham was not
    informed that the police might conduct more tests. Based on the warning,
    Mitcham consented to a blood draw.
    ¶7           The police drew two blood vials according to Mitcham’s 2015
    consent. One vial allowed the police to test for alcohol or drug
    concentration, and the second allowed Mitcham to test his blood
    independently. Mitcham and the police officer signed a “Destruction
    Notice,” which stated that if Mitcham did not pursue his opportunity to test
    3
    STATE v. MITCHAM
    Opinion of the Court
    within 90 days, his blood “sample will have been destroyed and
    unavailable for reanalysis.” The police tested their sample and determined
    Mitcham was over the legal limit, and he was later convicted of a
    misdemeanor DUI for this 2015 offense.
    ¶8           But the police did not destroy Mitcham’s blood sample after
    90 days passed and possessed it three years later when they identified that
    Mitcham might be the long-sought killer. The police—without obtaining a
    warrant—analyzed the blood from the 2015 DUI consent draw, creating
    Mitcham’s DNA profile. Mitcham’s profile matched the unknown DNA at
    the 2015 murder scene.
    ¶9            The police then sought a search warrant, requesting
    authorization to search Mitcham’s home and place a GPS tracker on his car.
    The search warrant affidavit noted that (1) the police had obtained DNA
    from the crime scene left by an unknown male source, (2) a familial DNA
    test of that profile revealed that the unknown DNA likely belonged to a
    father, son, or brother of inmate Mark Mitcham, and (3) Ian Mitcham had
    been identified as Mark Mitcham’s brother. The affidavit did not identify
    Mark Mitcham’s other relatives or explain why Ian Mitcham had
    specifically been selected for investigation. But the addresses of the victim
    and Ian Mitcham were in the affidavit. The affidavit revealed that Ian
    Mitcham’s blood sample was in the custody of the Scottsdale Police
    Department from his 2015 DUI arrest and that a DNA profile from the blood
    matched the unknown profile from the crime scene.
    ¶10           The court approved the search warrant. Mitcham was later
    arrested, and a buccal swab was taken as part of a routine booking
    procedure. See A.R.S. § 13-610(K), (O). The grand jury charged Mitcham
    with first-degree murder, second-degree burglary, and sexual assault.
    ¶11           Mitcham moved pretrial to suppress the DNA evidence from
    his 2015 DUI blood draw and the subsequent DNA buccal sample from his
    arrest. He argued that the “extraction and creation of a DNA profile from a
    consensual blood draw . . . was an unreasonable search under the Fourth
    Amendment” because it “went far beyond the scope of what was permitted
    by his prior consent in the unrelated DUI traffic stop.” He added that the
    DNA profile from his arrest buccal swab was the fruit of the original illegal
    search.
    ¶12          The superior court held an evidentiary hearing and granted
    the suppression motion. The court reasoned that though the police “may
    have been able to secure a warrant for [Mitcham’s] DNA through further
    4
    STATE v. MITCHAM
    Opinion of the Court
    diligent investigation,” the decision not to obtain a warrant “was at least a
    reckless violation of [Mitcham’s] constitutional rights.” The court also
    found it “troubling that the State essentially asserts that it has the unfettered
    ability to conduct subsequent searches of items held in custody for
    unrelated reasons.” The court also suppressed Mitcham’s DNA profile from
    the arrest buccal swab and any profile resulting from his convictions in the
    unrelated narcotics and aggravated DUI cases. Because the State intended
    to appeal, the superior court vacated the trial and stayed the proceedings.
    ¶13           The State appealed, and we have jurisdiction under Article 6,
    Section 9 of the Arizona Constitution and A.R.S. § 13-4032(6). See State v.
    Limon, 
    229 Ariz. 22
    , 24, ¶ 7 (App. 2011) (“[T]he plain language of § 13-4032
    allows the state to appeal from an ‘order granting a motion to suppress’
    without distinguishing between interlocutory or final orders.”).
    DISCUSSION
    ¶14           The State challenges the superior court’s application of the
    exclusionary rule to suppress the DNA evidence extracted from Mitcham’s
    2015 consensual blood draw. First, the State argues there was no Fourth
    Amendment violation because developing a DNA profile from lawfully
    obtained evidence is not a “second search.” Second, the State argues that
    even if there were a Fourth Amendment violation, Mitcham’s DNA profile
    should not have been suppressed because several exceptions applied.
    ¶15           We review a court’s factual findings on a motion to suppress
    for an abuse of discretion, State v. Smith, 
    250 Ariz. 69
    , 80, ¶ 16 (2020), and
    consider “only the evidence presented at the suppression hearing . . .
    viewing it in the light most favorable to sustaining the trial court’s ruling,”
    State v. 
    Thompson, 252
     Ariz. 279, 290, ¶ 26 (2022). But we review de novo the
    legal question of whether a search complied with the Fourth Amendment.
    Smith, 250 Ariz. at 80, ¶ 16.
    ¶16          The Fourth Amendment provides that “[t]he right of the
    people to be secure in their persons, houses, papers, and effects, against
    unreasonable searches and seizures, shall not be violated.” U.S. Const.
    amend. IV; see also Ariz. Const. art. 2, § 8 (“No person shall be disturbed in
    5
    STATE v. MITCHAM
    Opinion of the Court
    his private affairs, or his home invaded, without authority of law.”).1
    Traditionally, courts viewed search and seizure cases through a lens of
    “common-law trespass,” considering whether the state “obtain[ed]
    information by physically intruding on a constitutionally protected area.”
    See United States v. Jones, 
    565 U.S. 400
    , 405, 406, n.3 (2012). But this narrow
    approach has since been expanded. See 
    id.
     at 405–06. Because “the Fourth
    Amendment protects people, not places,” Katz v. United States, 
    389 U.S. 347
    ,
    351 (1967), it applies when an individual reasonably “seeks to preserve
    something as private,” Carpenter v. United States, 
    138 S. Ct. 2206
    , 2213 (2018)
    (quoting Smith v. Maryland, 
    442 U.S. 735
    , 740 (1979)). “A ‘search’ occurs
    when an expectation of privacy that society is prepared to consider
    reasonable is infringed.” United States v. Jacobsen, 
    466 U.S. 109
    , 113 (1984).
    ¶17           Under the Fourth Amendment, the basic rule is that “searches
    conducted outside the judicial process, without prior approval by judge or
    magistrate, are per se unreasonable . . . subject only to a few specifically
    established and well-delineated exceptions.” Arizona v. Gant, 
    556 U.S. 332
    ,
    338 (2009) (quoting Katz, 
    389 U.S. at 357
    ); accord State v. Valenzuela, 
    239 Ariz. 299
    , 302, ¶ 10 (2016). But “[t]he touchstone of the Fourth Amendment is
    reasonableness.” Florida v. Jimeno, 
    500 U.S. 248
    , 250 (1991).
    ¶18          It is well-settled that the drawing of blood by law
    enforcement, involving “intrusions into the human body,” is a search under
    the Fourth Amendment. See Schmerber v. California, 
    384 U.S. 757
    , 767 (1966).
    But whether DNA identification analysis of a blood sample originally
    drawn for a non-identification purpose is a search has not yet been decided.
    See Maryland v. King, 
    569 U.S. 435
    , 464–65 (2013). In determining this issue,
    we are guided by two cases, King and Mario W. v. Kaipio, 
    230 Ariz. 122
    (2012).
    1       In the superior court, the parties did not address whether the
    creation of Mitcham’s DNA profile violated his state constitutional rights
    as distinct from his rights under the federal Fourth Amendment. On appeal,
    Mitcham asserts that the right to privacy under the Arizona Constitution
    “is broader than its federal counterpart against searches and seizures,”
    providing an independent state ground to uphold the suppression. We do
    not consider this contour, as the Arizona Supreme Court has declined “to
    expand the Private Affairs Clause’s protections beyond the Fourth
    Amendment’s reach, except in cases involving warrantless home entries.”
    State v. Mixton, 
    250 Ariz. 282
    , 290, ¶ 32 (2021).
    6
    STATE v. MITCHAM
    Opinion of the Court
    A.    Under Mario W., the Creation of a DNA Profile from State-Held
    Evidence Is a Search, but It Does Not Require a Warrant If There Is
    Probable Cause or Reasonable Suspicion.
    ¶19            Our supreme court in Mario W. addressed whether juveniles
    facing delinquency charges could be compelled to submit to DNA
    extraction and profiling before those charges were adjudicated as a
    statutory condition of release. 
    230 Ariz. at 125, ¶ 12
    ; see A.R.S. § 8-238(A).
    The court noted that the process involved “two separate intrusions on [the
    juveniles’] privacy,” distinguishing between the seizing of the buccal cells
    and the processing of the seized cells to create a DNA profile. Id. at 126–27,
    ¶ 18. Applying a “two-tiered approach,” id. at 127, ¶ 20, the court first held
    that the seizure of the cells was a justifiable measure to ensure that the
    juveniles did not abscond, id. at 128, ¶ 24. “A judicial order to provide a
    buccal cell sample occasions no constitutionally distinguishable intrusion”
    from an order to provide fingerprints. Id. at ¶ 25. But the court rejected the
    statute’s authorization to create profiles because DNA reveals “uniquely
    identifying information” and there was “no strong governmental interest
    in creating DNA profiles.” Id. at 127, 129, ¶¶ 20, 28.
    ¶20           The State asserts that Maryland v. King “necessarily modified”
    Mario W. It argues that Mario W. “cannot be reconciled with King’s express
    holding that ‘the processing of respondent’s DNA sample’s 13 CODIS loci
    did not intrude on respondent’s privacy in a way that would make his DNA
    identification unconstitutional.’” King, 
    569 U.S. at 464
    . The State reads King
    too broadly.
    ¶21           In King, the United States Supreme Court considered the
    constitutionality of a Maryland statutory requirement that arrestees
    charged with “serious crimes” have buccal swabs taken and a CODIS
    profile created. King, 
    569 U.S. at
    443–45. The Court held that taking and
    analyzing buccal swabs was a search but that the search was a reasonable
    “routine booking procedure.” 
    Id.
     at 465–66. The Court first noted that
    arrestees had diminished expectations of privacy. 
    Id. at 462
    . The Court then
    evaluated the degree of the intrusion, deciding that it was minimal. 
    Id.
     at
    463–64. The Court reasoned that “CODIS loci come from noncoding parts
    of the DNA that do not reveal the genetic traits of the arrestee.” 
    Id. at 464
    .
    But the Court acknowledged that “science can always progress further,”
    which “may have Fourth Amendment consequences.” 
    Id.
     The Court upheld
    the Maryland statute by balancing the reduced privacy interest against the
    minimal privacy invasion—given the “statutory protections that guard
    against further invasion of privacy.” 
    Id.
     at 465–66.
    7
    STATE v. MITCHAM
    Opinion of the Court
    ¶22           King overruled Mario W. to a degree.2 But King did not hold
    that taking a buccal swab was not a search. The King Court only decided
    that taking and processing a swab for DNA identification was reasonable
    upon arrest for a serious crime. 
    569 U.S. at
    465–66. Because King did not
    address whether DNA profiling—divorced from the physical process of its
    collection upon arrest—is a search, we are still bound by Mario W.’s
    conclusion that it is.3 See Mario W., 
    230 Ariz. at 129, ¶ 32
    . So we begin our
    analysis with Mario W.
    ¶23            In Mario W., our supreme court did not hold that DNA
    analysis always requires a warrant. Instead, Mario W. held that the State
    could not extract a DNA profile from buccal swabs “absent either probable
    cause or reasonable suspicion.” 
    230 Ariz. at 129, ¶ 31
    . And Mario W. further
    suggested that the absconding of a charged juvenile would provide
    sufficient justification to create a DNA profile. Id. at ¶ 30. Thus, Mario W.
    and King harmonize in concluding that whether DNA profiling violates the
    2      We must follow Arizona Supreme Court decisions absent conflicting
    United States Supreme Court decisions on the same subject. See State v.
    Crowley, 
    202 Ariz. 80
    , 90, ¶ 30 (App. 2002); Hernandez-Gomez v. Volkswagen
    of Am., Inc., 
    201 Ariz. 141
    , 143–44, ¶ 8 (App. 2001). As much as King and
    Mario W. addressed the same subject, we are bound to follow King.
    3      Mario W.’s holding does conflict with other jurisdictions that have
    addressed this question after King. See, e.g., Commonwealth v. Arzola, 
    26 N.E.3d 185
    , 191 (Mass. 2015) (“[T]he DNA analysis of the unknown sample
    taken from the defendant’s lawfully seized shirt revealed nothing more
    than the identity of the source, which is what an analysis of latent
    fingerprints would have revealed (albeit with less accuracy) had they been
    found on the clothing. Therefore, the DNA analysis was no more a search
    than an analysis of latent fingerprints would be.”); Raynor v. State, 
    99 A.3d 753
    , 767–68 (Md. 2014) (“[W]e hold that DNA testing of the 13 identifying
    junk loci within genetic material, not obtained by means of a physical
    intrusion into the person’s body, is no more a search for purposes of the
    Fourth Amendment, than is the testing of fingerprints, or the observation
    of any other identifying feature revealed to the public—visage, apparent
    age, body type, skin color. That Petitioner’s DNA could have disclosed
    more intimate information is of no moment in the present case because
    there is no allegation that the police tested his DNA sample for that
    purpose.”); accord People v. Mendez, 
    155 N.Y.S.3d 534
    , 536–37 (Sup. Ct. 2021);
    Hedvall v. State, 
    283 So.3d 901
    , 920 (Fla. Dist. Ct. App. 2019).
    8
    STATE v. MITCHAM
    Opinion of the Court
    Fourth Amendment turns on the reasonableness of the process. Against this
    backdrop, we consider the arguments before us.
    ¶24            First, we reject the broad position urged by amici supporting
    the defense—that analyzing genetic material and generating a DNA profile
    “constitutes a search and seizure” and always requires a warrant. Such a
    restrictive view would “impose[] substantial burdens on law enforcement
    without vindicating any significant values of privacy.” See Robbins v.
    California, 
    453 U.S. 420
    , 429 (1981) (Powell, J., concurring). Moreover, a
    holding that “[t]he government must therefore obtain a warrant to search
    or seize DNA” cannot be harmonized with King, which permitted
    warrantless, suspicionless DNA profiling of arrestees charged with
    “serious crimes,” or Mario W., which permitted it under some
    circumstances for juveniles taken into custody facing delinquency charges.
    ¶25            Of course, we agree that courts must take caution when it
    comes to DNA, as a “vast amount of sensitive information . . . can be
    mined,” United States v. Amerson, 
    483 F.3d 73
    , 85 (2d Cir. 2007), that
    “reveal[s] a host of private medical facts,” Skinner v. Ry. Lab. Execs.’ Ass’n,
    
    489 U.S. 602
    , 617 (1989). And it may be true that the DNA analyzed for
    CODIS4 contains medical information that will become accessible as
    technology advances. See King, 
    569 U.S. at 464
     (Though noncoding parts of
    the DNA are used, “science can always progress further, and those
    progressions may have Fourth Amendment consequences.”). But as King
    explained, the identification profile generated from the DNA does not
    reveal any medical data. See 
    id. at 445
    . The identification number
    comprising the profile is no more intrusive than a nametag on a suitcase or
    a license plate number on a car.
    ¶26          Furthermore, unlike a blood-alcohol report, cell phone
    records, or a contraband package, this “string of numbers” alone is not
    evidence of a crime. See King, 
    569 U.S. at 445, 451
     (“Like a fingerprint, the
    13 CODIS loci are not themselves evidence of any particular crime, in the
    way that a drug test can by itself be evidence of illegal narcotics use. A DNA
    4      “The CODIS database is based on 13 loci at which the STR [short
    tandem repeat] alleles are noted and compared. . . . The CODIS loci are from
    the non-protein coding junk regions of DNA” and are “only useful for
    human identity testing.” King, 
    569 U.S. at 445
    . “STR information is recorded
    only as a ‘string of numbers’; and the DNA identification is accompanied
    only by information denoting the laboratory and the analyst responsible for
    the submission.” 
    Id.
    9
    STATE v. MITCHAM
    Opinion of the Court
    profile is useful to the police because it gives them a form of identification
    to search the records already in their valid possession. In this respect the
    use of DNA for identification is no different than matching an arrestee’s
    face to a wanted poster of a previously unidentified suspect; or matching
    tattoos to known gang symbols to reveal a criminal affiliation; or matching
    the arrestee’s fingerprints to those recovered from a crime scene.”). Decades
    ago, the United States Supreme Court approved using an identity-based
    rule-out test if there is particularized suspicion and the test is minimally
    intrusive. See Hayes v. Florida, 
    470 U.S. 811
    , 817 (1985) (“[T]he Fourth
    Amendment would permit seizures for the purpose of fingerprinting, if
    there is reasonable suspicion that the suspect has committed a criminal act,
    if there is a reasonable basis for believing that fingerprinting will establish
    or negate the suspect’s connection with that crime, and if the procedure is
    carried out with dispatch.”).
    ¶27          Given the limited information currently available from a
    CODIS DNA profile, creating a DNA profile from evidence in the State’s
    possession does not always require a search warrant.
    B.   Searches Beyond the Scope of Authorization Are Unreasonable
    Under the Fourth Amendment.
    ¶28            The first step in applying King and Mario W. is determining
    how the genetic material came into the State’s possession. In King and
    Mario W., the State obtained the genetic material under statutory authority
    on arrest. See King, 
    569 U.S. at 441
    ; Mario W., 
    230 Ariz. at 124, ¶ 2
    .5 Unlike
    King and Mario W., the State possessed Mitcham’s blood sample via consent
    from the 2015 DUI arrest.
    ¶29          Mitcham argues that the subsequent DNA analysis in 2018
    exceeded the scope of that consent. The State counters that the Fourth
    Amendment is no longer implicated once a biological sample has been
    lawfully and physically extracted from a suspect. The State minimizes the
    5      “The Attorney General may, as prescribed by the Attorney General
    in regulation, collect DNA samples from individuals who are arrested.” 
    34 U.S.C. § 40702
    (a)(1)(A). And the Attorney General may provide grants to
    state and local governments that analyze DNA profiles under local
    authority for inclusion in CODIS. 
    34 U.S.C. § 40701
    (a)(1). As of the date of
    the decision in King, it was noted: “Twenty-eight States and the Federal
    Government have adopted laws . . . authorizing the collection of DNA from
    some or all arrestees.” 
    569 U.S. at 445
    .
    10
    STATE v. MITCHAM
    Opinion of the Court
    consent issue, emphasizing that consent’s scope “no longer matter[s]” once
    the blood is in the State’s lawful possession.
    ¶30            As much as the State asserts that lawful possession is always
    sufficient to justify warrantless DNA analysis, the law provides otherwise.
    See United States v. Davis, 
    690 F.3d 226
    , 246 (4th Cir. 2012) (Supreme Court
    precedent did “not give a law enforcement agency carte blanche [authority]
    to perform DNA extraction and analysis derived from clothing lawfully
    obtained from the victim of a crime in relation to the investigation of other
    crimes.”). The Supreme Court has long clarified that even lawful possession
    of a suspect’s property does not allow the State to do whatever it wants
    with that property. See, e.g., Walter v. United States, 
    447 U.S. 649
    , 654 (1980)
    (“The fact that FBI agents were lawfully in possession of the boxes of film
    did not give them authority to search their contents.”); United States v.
    Chadwick, 
    433 U.S. 1
    , 15–16 (1977) (A steamer trunk was lawfully seized but
    a warrant was needed to open and determine its contents.), abrogated on
    other grounds by California v. Acevedo, 
    500 U.S. 565
     (1991); Riley v. California,
    
    573 U.S. 373
    , 401 (2014) (The seizure of a cell phone does not permit
    warrantless access to information within the phone.). This is because a
    person’s interest in keeping information private does not vanish once the
    vessel of that information is held in police custody. A biological sample
    containing extractable DNA is no different.
    C.   DNA Testing that Exceeds the Scope of Consent or Warrant
    Renders the State’s Possession Unlawful.
    ¶31            The State argues that the way it obtains evidence, so long as it
    is done lawfully, is irrelevant. We disagree. See Terry v. Ohio, 
    392 U.S. 1
    , 29
    (1968) (“[E]vidence may not be introduced if it was discovered by means of
    a seizure and search which were not reasonably related in scope to the
    justification for their initiation.”). In other contexts, a suspect may grant
    limited consent to a police search but retain an expectation of privacy in
    areas beyond the scope of that consent. See, e.g., State v. Swanson, 
    172 Ariz. 579
    , 584 (App. 1992) (“[C]onsent to ‘take a look in the vehicle’ does not
    encompass the further intrusion of ‘tearing a car apart’ by removing the
    door panels.”); State v. Paredes, 
    167 Ariz. 609
    , 612 (App. 1991) (“The scope
    of a consensual search is limited to the scope of the consent given.”); State
    v. Florez, 
    195 Ariz. 199
    , 205, ¶ 26 (App. 1999) (same). And the same rule
    applies to searches authorized by warrant or exigency. See Walter, 
    447 U.S. at 656
     (“When an official search is properly authorized—whether by
    consent or by the issuance of a valid warrant—the scope of the search is
    limited by the terms of its authorization.”); see also Arizona v. Hicks, 
    480 U.S. 321
    , 325 (1987) (“[A]ction, unrelated to the objectives of the authorized
    11
    STATE v. MITCHAM
    Opinion of the Court
    intrusion . . . produce[d] a new invasion of respondent’s privacy unjustified
    by the exigent circumstance that validated the entry.”).
    ¶32            A hypothetical helps clarify this point. A homeowner’s
    consent to police to enter a home to seize a briefcase would not authorize
    the police to begin collecting hair or skin cells from the homeowner’s carpet.
    This is true even though (1) the collection of cells left in public is generally
    permissible, and (2) the officers had permission to enter the home. Under
    the consent, the officers would only be authorized to do what they
    requested permission to do—seize the briefcase.6
    ¶33           Consent to a blood draw for testing for intoxicants does not
    authorize the police to create a DNA profile from the cells in that blood to
    investigate unrelated offenses. It does not matter that (1) blood cells found
    in public can be DNA tested or (2) the police had lawfully obtained the
    blood for chemical analysis. Under the consent provided, the police could
    search for drugs or alcohol. But the later creation of a DNA profile is as
    much an unconsented privacy violation as the unrequested collection of
    DNA samples from within a home.
    ¶34            Still, the State claims, without explanation, that it is “hard to
    analogize blood or one’s DNA profile to a portion of a home, package,
    vehicle, clothing, cell phone, computer or other private piece of property to
    which one usually may want the ability to ‘limit’ the ‘scope’ of their
    consent.” Given the medical information in one’s blood, we have no such
    difficulty. See Mario W., 
    230 Ariz. at 127, ¶ 20
     (DNA analysis “is, in effect,
    the analog to opening the steamer trunk in Chadwick and the purse in
    Tiffany O. to see what is inside.”). See generally In re Tiffany O., 
    217 Ariz. 370
    (App. 2007).
    ¶35             Mitcham consented to a blood draw during the 2015 DUI
    arrest. Thus, the relevant question is whether the later creation of the DNA
    profile for use independent of the DUI fell within Mitcham’s consent. See
    State v. Becerra, 
    239 Ariz. 90
    , 92, ¶ 8 (App. 2016). “The standard for
    measuring the scope of a suspect’s consent under the Fourth Amendment
    is that of ‘objective’ reasonableness.” Jimeno, 
    500 U.S. at 251
    . And “[w]hether
    a consensual search remained within the bounds of the actual consent is a
    6       Of course, the police may also seize evidence of a crime in plain view
    if the police are lawfully within the home. See generally Coolidge v. New
    Hampshire, 
    403 U.S. 443
    , 465–66 (1971). For simplicity, we omit discussion
    of this exception because it is not relevant here.
    12
    STATE v. MITCHAM
    Opinion of the Court
    question of fact to be determined from the totality of circumstances.”
    Swanson, 172 Ariz. at 583.
    ¶36           Under the Admin Per Se Implied Consent agreement,
    Mitcham consented to the taking and analyzing of his blood “to determine
    alcohol concentration or drug content.” The written consent admonition
    did not authorize the creation of a DNA profile to investigate unrelated
    offenses or for unrelated crime detection. The consent form allowed the
    police to determine only what percentage of the sample comprised alcohol
    or intoxicating drugs. Given these facts, the superior court did not abuse its
    discretion by finding that creating a DNA profile from Mitcham’s 2015
    blood draw exceeded the scope of his consent to draw the blood. And action
    outside the scope of consent renders the State’s evidence unlawful, no
    matter how minimally intrusive. See Hicks, 
    480 U.S. at 325
     (“A search is a
    search, even if it happens to disclose nothing but the bottom of a
    turntable.”).
    D.    Despite the Fourth Amendment Violation, the Superior Court
    Erred by Suppressing Mitcham’s DNA Profile.
    ¶37            “[T]o say that the Fourth Amendment applies here is the
    beginning point, not the end of the analysis.” King, 
    569 U.S. at 446
    ; see also
    Nix v. Williams, 
    467 U.S. 431
    , 444 (1984). “The Fourth Amendment protects
    the right to be free from ‘unreasonable searches and seizures,’ but it is silent
    about how this right is to be enforced.” Davis v. United States, 
    564 U.S. 229
    ,
    230–31 (2011).
    ¶38           “The exclusionary rule, which allows suppression of evidence
    obtained in violation of the Fourth Amendment, is a prudential doctrine
    invoked to deter future violations.” Valenzuela, 
    239 Ariz. at
    308–09, ¶ 31.
    Exclusion is “not a personal constitutional right,” nor is it designed to
    “redress the injury” occasioned by an unconstitutional search. Stone v.
    Powell, 
    428 U.S. 465
    , 486 (1976). “The rule’s sole purpose . . . is to deter future
    Fourth Amendment violations.” Davis, 
    564 U.S. at
    236–37. Thus, the rule is
    appropriate only when deterrence is necessary, and the “substantial social
    costs” are accounted for. 
    Id. at 237
    . Given the “enormous societal cost of
    excluding truth,” suppression of evidence should not place the police in a
    worse position than they would have been without the illegal conduct. See
    Nix, 
    467 U.S. at
    443–45; Sutton v. United States, 
    267 F.2d 271
    , 272 (4th Cir.
    1959) (“It is one thing to say that officers shall gain no advantage from
    violating the individual’s rights; it is quite another to declare that such a
    violation shall put him beyond the law’s reach even if his guilt can be
    proved by evidence that has been obtained lawfully.”).
    13
    STATE v. MITCHAM
    Opinion of the Court
    1.   The State Had Probable Cause to Arrest Mitcham Even
    Without the DNA Profile Showing a Match.
    ¶39          Creating a DNA profile from Mitcham’s 2015 DUI blood
    sample was an unauthorized search. But the superior court also suppressed
    subsequent DNA collection and analysis as the fruit of the poisonous tree.
    See Wong Sun v. United States, 
    371 U.S. 471
    , 484 (1963); Brown v. Illinois, 
    422 U.S. 590
    , 599–600 (1975). We reverse the suppression order because the
    police had probable cause to arrest Mitcham even without the DNA match
    from the 2015 blood draw.
    ¶40           It is unclear from the record whether Mitcham was arrested
    under an arrest warrant or the police’s statutory arrest authority. See A.R.S.
    § 13-3883(A)(1). Though the superior court ordered the suppression of
    “subsequent DNA swabs collected pursuant to the warrant,” there is no
    such warrant in the record before us. The affidavit submitted for a search
    warrant (for a search of Mitcham’s home and GPS tracking of his car) noted
    the DNA profile derived from Mitcham’s 2015 DUI blood sample, but that
    warrant was not the basis for collecting buccal swabs here.
    ¶41            In any event, A.R.S. § 13-610(K) directs that when a person
    arrested for a serious offense is transferred to jail, the arresting authority
    “shall secure a sufficient sample of buccal cells or other bodily substances
    for deoxyribonucleic acid testing and extraction from the person for the
    purpose of determining identification characteristics.” Because the
    procurement of a buccal swab from Mitcham would have been required
    upon his arrest for first-degree murder, the relevant question is whether the
    police had probable cause to arrest Mitcham without the
    improperly-obtained DNA match from the 2015 blood draw. See A.R.S.
    § 13-3883(A)(1); cf. State v. Sardo, 
    112 Ariz. 509
    , 515 (1975) (quoting United
    States v. Kandlis, 
    432 F.2d 132
    , 135 (9th Cir. 1970)) (“This is a case where ‘the
    arrest and search are inextricably intertwined. The officers could neither
    arrest nor search without probable cause; if they had probable cause, they
    could do both.’”).
    ¶42            “To determine whether an officer had probable cause for an
    arrest,” we determine whether the “facts, viewed from the standpoint of an
    objectively reasonable police officer, amount to probable cause.” District of
    Columbia v. Wesby, 
    138 S. Ct. 577
    , 586 (2018) (quoting Maryland v. Pringle,
    
    540 U.S. 366
    , 371 (2003)). We consider de novo the mixed question of whether
    the facts presented established probable cause. State v. Buccini, 
    167 Ariz. 550
    , 555 (1991).
    14
    STATE v. MITCHAM
    Opinion of the Court
    ¶43           Without resorting to the DNA profile from Mitcham’s 2015
    DUI blood sample and even without resorting to evidence developed from
    the warrant-based search of Mitcham’s home and GPS tracking, the police
    had probable cause for the arrest. The familial DNA result, obtained
    independently, established that the unknown DNA at the crime scene
    matched inmate Mark Mitcham’s first-degree relative, meaning a father,
    son, or brother. At the suppression hearing, the police testified that Mark’s
    father was dead, Mark’s two sons lived out of state, and Mark had two
    brothers in the Phoenix area, one of whom was Ian Mitcham. The police
    also noted that the addresses of Ian Mitcham and the victim were close and
    that Ian Mitcham’s 2015 DUI arrest occurred in Scottsdale.
    ¶44           Probable cause for an arrest is present when the arresting
    officer knows “facts and circumstances . . . sufficient to warrant a man of
    reasonable caution to believe that a felony had been committed by the
    person arrested.” Sardo, 
    112 Ariz. at 515
     (quoting State v. Edwards, 
    111 Ariz. 357
    , 360 (1974)). It “requires only a probability or substantial chance of
    criminal activity, not an actual showing of such activity,” Illinois v. Gates,
    
    462 U.S. 213
    , 243, n.13 (1983), and “is not a high bar,” Kaley v. United States,
    
    571 U.S. 320
    , 338 (2014).
    ¶45            While the evidence is no doubt weaker without the
    information about the DNA match from the 2015 blood draw, the familial
    match and Mitcham’s proximity to the crime scene would provide a “man
    of reasonable caution” to believe that Mitcham may have committed the
    murder. See Sardo, 
    112 Ariz. at 515
    . And Mitcham has never challenged the
    validity of his arrest independently from his challenge to the results of the
    2015 DNA profiling. In fact, at oral argument before this court, Mitcham
    conceded that the police had probable cause to support his arrest even
    without the DNA match evidence.
    ¶46            Thus, while the DNA profile from the 2015 blood sample was
    impermissibly obtained, the evidence independent of that DNA profile
    provided sufficient probable cause to authorize Mitcham’s arrest. And once
    Mitcham was arrested for first-degree murder, the police were required to
    take a buccal swab and extract a DNA profile independent of the prior
    violation. See A.R.S. § 13-610(K). For these reasons, we conclude that the
    superior court’s order suppressing Mitcham’s DNA profile as a fruit of the
    illegal search was error.
    15
    STATE v. MITCHAM
    Opinion of the Court
    2.    The DNA Evidence Would Have Inevitably Been Obtained
    from Mitcham’s Other Felony Convictions.
    ¶47           Another independent basis exists for reversing the court’s
    suppression order. Mitcham’s DNA is already in CODIS because of his
    felony convictions in 2022. Mitcham’s later convictions for unrelated crimes
    provide an independent source for the State to possess Mitcham’s DNA
    profile, proving that his profile would have inevitably been discovered
    even had the police not created a profile in 2018. As a result, the State argues
    that the inevitable discovery doctrine should apply to prevent suppression
    of Mitcham’s DNA profile.
    ¶48          In reply, Mitcham seeks to distinguish the “independent
    source” and “inevitable discovery” doctrines, claiming that failing to fully
    elaborate on both arguments below results in a waiver on appeal. We
    disagree. We see no value in requiring the State to develop both “closely
    related” doctrines fully, see Nix, 
    467 U.S. at 443
    , especially when, as here,
    the arguments amount to the same thing: Mitcham’s 2022 felony
    convictions are an independent and inevitable cause of the creation of his
    CODIS profile.
    ¶49           Mitcham also counters that he only “pled guilty as a strategic
    choice” to his two felonies because of the pending murder charge against
    him. He implies that his convictions for aggravated DUI and narcotics
    offenses are fruits of the purported illegal search, so the court cannot
    consider them in an inevitable discovery analysis.
    ¶50            This argument is meritless. Mitcham does not allege that his
    pleas were involuntary or not supported by a factual basis, merely that it
    was a “strategic choice” for him to enter those guilty pleas. In any event, a
    “plea is itself a conviction and like a jury verdict is conclusive.” State v.
    Linsner, 
    105 Ariz. 488
    , 491 (1970). Under the law, Mitcham is guilty of those
    offenses, and the State must submit his DNA to the federal CODIS database
    under A.R.S. § 13-610.
    ¶51          Because the police would have acquired Mitcham’s DNA
    profile even without the search of the 2015 blood draw, the superior court
    erred by suppressing Mitcham’s DNA profile.
    CONCLUSION
    ¶52         We reverse the order suppressing Mitcham’s DNA profile
    and remand for further proceedings consistent with this opinion.
    16
    STATE v. MITCHAM
    Catlett, J., Concurring
    CATLETT, Judge, concurring in the judgment:
    ¶53          I concur in the judgment reversing the suppression order.
    Unlike the majority, however, I would not reach the inevitable discovery
    issue. Mitcham did not have a reasonable expectation of privacy in the non-
    coding regions of DNA the State lawfully possessed in 2018. Thus, no
    search and no Fourth Amendment violation occurred.
    I.
    ¶54           The majority correctly explains the background in Mario W. v.
    Kaipio, 
    230 Ariz. 122
     (2012), and Maryland v. King, 
    569 U.S. 435
     (2013). Mario
    W. held that extracting and profiling a juvenile’s DNA for pre-trial
    processing involved two distinct searches—one upon extraction, one upon
    profiling. 
    230 Ariz. at
    126—27 ¶ 18. The court then analyzed whether the
    two searches were reasonable in the absence of a warrant. The court
    concluded the first search—extracting a juvenile’s DNA—was reasonable
    even without a warrant. 
    Id.
     at 128 ¶ 25. The court concluded the second
    search—obtaining the DNA profile from the sample—was unreasonable
    when a juvenile has not absconded. 
    Id.
     at 129 ¶ 32.
    ¶55           The State argues King renders Mario W. “untenable.” The
    majority is correct that, although King overrules a portion of Mario W.’s
    reasonableness analysis, it does not overrule Mario W.’s holding that
    profiling a juvenile’s DNA under the statute at issue was a search separate
    and apart from DNA extraction. Maj. Op. ¶ 22.
    ¶56           Yet the majority’s subsequent analysis and application of
    Mario W. is perplexing. The majority concludes that Mario W. “did not hold
    that DNA analysis always requires a warrant” and similarly rejects that
    “analyzing genetic material and generating a DNA profile ‘constitutes a
    search and seizure’ and always requires a warrant.” Maj. Op. ¶¶ 23, 24.
    Both that conclusion and rejection are sound. But the majority fails to
    explain the import of those observations. Does DNA analysis always
    constitute a search? Or does DNA analysis only sometimes constitute a
    search? If DNA analysis is only sometimes a search, when is it a search and
    when is it not? Why was the DNA analysis here a search? The majority
    does not clarify.
    ¶57          The majority, for example, acknowledges a split among state
    courts regarding whether a search occurs when the government creates a
    DNA profile using lawfully possessed blood. See Maj. Op. ¶ 22 n.3. The
    17
    STATE v. MITCHAM
    Catlett, J., Concurring
    majority then appears to take sides with those courts requiring a warrant or
    a warrant exception (thereby extending Mario W. to criminal
    investigations). See Maj. Op. ¶¶ 29-36. The majority analyzes the
    reasonableness of the police conduct at issue here (which would be
    unnecessary unless a search occurred), and then concludes that profiling
    Mitcham’s DNA was unreasonable because the State exceeded the scope of
    Mitcham’s consent. But, in so doing, the majority largely skips the crucial
    question in this case: whether the State conducted a new search in 2018.
    ¶58            The majority also extends statements in Mario W. too far in
    favor of the State, arguably creating a new warrant exception in the process.
    The majority says Mario W. held that a warrant is not required to create a
    DNA profile if there is probable cause or reasonable suspicion to believe an
    individual committed another crime. See Maj. Op. ¶ 23. The heading of
    that section of the majority opinion says, “Under Mario W., the Creation of
    a DNA Profile from State-Held Evidence Is a Search, but It Does Not Require
    a Warrant If There Is Probable Cause or Reasonable Suspicion.” Maj. Op. p.7
    (emphasis added). To be sure, Mario W. says that its analysis might differ
    with probable cause or reasonable suspicion. 
    230 Ariz. at
    129 ¶ 31; see infra
    ¶ 83 (using probable cause as one factor in the search analysis). But Mario
    W. did not create a new probable cause or reasonable suspicion exception
    to the warrant requirement for DNA profiles. Such an exception could
    diminish—if not swallow—the warrant requirement. It is also inconsistent
    with the majority’s later conclusion that a Fourth Amendment violation
    occurred here (the majority says there was probable cause that Mitcham
    committed another crime (murder)).
    ¶59           There is a more direct route to resolving the constitutional
    issue—the route both parties urge us to take. Whether the State violated
    the Fourth Amendment turns, not on reasonableness or the existence of a
    new warrant exception, but on whether the State conducted a new search
    in 2018. Taking that route requires answering only two questions. Does
    Mario W.’s holding that the creation of a juvenile’s DNA profile is a search
    unto itself govern every time the government creates a DNA profile? If not,
    did Mitcham have a reasonable expectation of privacy in 2018 in the non-
    coding regions of DNA he provided in 2015?
    II.
    ¶60          Mario W. did not establish a universal rule that creating a
    DNA profile is always a search separate from DNA extraction. Mario W.
    did not analyze expectations of privacy in DNA in all circumstances—an
    impossible task. Rather, Mario W. involved a unique situation—a statute
    18
    STATE v. MITCHAM
    Catlett, J., Concurring
    requiring juveniles merely charged with certain offenses to undergo DNA
    profiling. See 
    230 Ariz. at
    123 ¶ 1. The statute mandated DNA profiling
    when there was not even reasonable suspicion “that a juvenile committed
    another offense for which the DNA profile might provide investigative
    assistance.” 
    Id.
     at 125 ¶ 9.
    ¶61           Determining the reasonable expectations of juveniles in the
    non-investigative circumstances in Mario W. is a far cry from what we
    analyze here—the privacy expectations of an adult who was convicted of
    the crime for which he provided blood when the police later, with probable
    cause and for investigational purposes, create a DNA profile from that
    sample. Mario W. does not attempt to answer, let alone dictate the answer
    to, that Fourth Amendment dilemma—either for or against Mitcham. We
    should read general language in judicial opinions “as referring in context
    to circumstances similar to the circumstances then before the Court and not
    referring to quite different circumstances that the Court was not then
    considering.” Illinois v. Lidster, 
    540 U.S. 419
    , 424 (2004). Mario W.’s two-
    search holding stems from the unique circumstances in which it was created
    and not the dissimilar circumstances we face.
    ¶62            I am not alone in concluding Mario W. is inapplicable here.
    One of Mitcham’s amici refers to Mario W. as conducting a “troublesome
    ‘two-tiered’ analysis” and asks us to apply a “holistic approach” instead.
    Similarly, Mitcham repeatedly argues that Mario W. does not apply. For
    example, he asserts “Mario W. is largely inapplicable because it did not
    address . . . warrantless DNA searches for criminal investigation purposes.”
    Mitcham also argues that “[t]his case does not involve a challenge” like that
    in Mario W., and therefore “this Court need not address whether Mario W.
    must be overruled.” I agree with Mitcham on both points.
    III.
    ¶63          If Mario W. does not resolve the Fourth Amendment question,
    where does that leave us? Here is where: in 2018, Mitcham did not have a
    reasonable expectation of privacy in the non-coding regions of DNA he
    provided in 2015, and the State therefore did not conduct a new search
    when it created a DNA profile. With no search, there was no Fourth
    Amendment violation.
    A.
    ¶64          The Fourth Amendment, binding on the State through the
    Fourteenth Amendment, provides “[t]he right of the people to be secure in
    their persons, houses, papers, and effects, against unreasonable searches
    19
    STATE v. MITCHAM
    Catlett, J., Concurring
    and seizures, shall not be violated, and no Warrants shall issue, but upon
    probable cause.” U.S. Const. amend. IV. As the text says, the right protects
    against “unreasonable searches and seizures.” U.S. Const. amend. IV. If
    neither a search nor a seizure occurs, the Amendment has no role. This is a
    search case; Mitcham does not frame this as a seizure case.
    ¶65          There are two approaches to determining whether a “search”
    occurs—the property approach and the privacy approach. See Soldal v. Cook
    County, 
    506 U.S. 56
    , 64 (1992) (“[P]roperty rights are not the sole measure of
    Fourth Amendment violations.”). Mitcham relies only on the privacy
    approach.
    B.
    ¶66           The privacy approach—Justice Harlan’s creation in a
    concurring opinion in Katz v. United States, 
    389 U.S. 347
    , 361 (1967) (Harlan,
    J., concurring)—asks whether “an individual ‘seeks to preserve something
    as private’ and that expectation is ‘one that society is prepared to recognize
    as reasonable.’” State v. Mixton, 
    250 Ariz. 282
    , 286 ¶ 13. “[O]fficial intrusion
    into that private sphere generally qualifies as a search and requires a
    warrant supported by probable cause.” Carpenter v. United States, 
    138 S. Ct. 2206
    , 2213 (2018).
    ¶67           The “reasonable expectation of privacy” test can be difficult
    to apply in practice. One Fourth Amendment scholar has observed that
    “[t]reatises and casebooks struggle to explain the test,” with “some
    suggest[ing] that the only way to identify when an expectation of privacy
    is reasonable is when five Justices say so.” Orin S. Kerr, Four Models of
    Fourth Amendment Protection, 
    60 Stan. L. Rev. 503
    , 505 (2007). To avoid
    letting the test lead us into judicial policymaking, we should treat it as
    posing a descriptive question: whether society recognized the proffered
    expectation of privacy at the time of the alleged search. See Carpenter, 
    138 S. Ct. at 2245
     (Thomas, J., dissenting) (“As written, the Katz test turns on
    society’s actual, current views about the reasonableness of various
    expectations of privacy.”). And we should answer the “reasonable
    expectation” question by looking to pre-existing law—statutes, regulations,
    and prior Fourth Amendment and common law precedent. See Baude &
    Stern, The Positive Law Model of the Fourth Amendment, 
    129 Harv. L. Rev. 1821
    , 1852 (2016) (“[T]he positive law model calls for the bread and butter
    of the legal profession—doctrinal analysis. It is a task that is both more
    appropriate to judges’ roles and more suited to their capabilities.”).
    20
    STATE v. MITCHAM
    Catlett, J., Concurring
    C.
    ¶68          There are four factors that, when existing together7, dictate
    that Mitcham did not have a reasonable expectation of privacy in 2018 in
    the non-coding regions of DNA in the 2015 blood sample.
    1.
    ¶69            The State used only the non-coding regions of Mitcham’s
    DNA to determine whether it matched non-coding regions in DNA found
    at the murder scene. The non-coding regions of DNA, also known as “junk
    DNA,” “while useful and even dispositive for purposes like identity, does
    not show more far-reaching and complex characteristics like genetic traits.”
    King, 
    569 U.S. at 443
    . Forensic analysis of the non-coding region focuses on
    “short tandem repeats” (“STRs”) scattered throughout the genetic code. 
    Id.
    The size and frequency of STRs “along a strand of DNA” are known as
    alleles. 
    Id.
     Forensic DNA analysis uses multiple alleles “to ensure that a
    DNA profile matches only one individual.” 
    Id.
     Using STRs to analyze
    alleles in non-coding regions, “makes it possible to determine whether a
    biological tissue matches a suspect with near certainty.” 
    Id.
    ¶70            The State’s comparison between an STR-generated DNA
    profile and a fingerprint is apt. Like a fingerprint, the information provided
    in an STR-generated DNA profile tells you nothing about an individual, let
    alone anything private. Instead, the sequence of numbers produced is so
    unique that it can be used to connect two genetic samples, thereby
    confirming identification. Cf. United State v. Mitchell, 
    652 F.3d 387
    , 412 (3d
    Cir. 2011) (“[B]ecause DNA profiles developed pursuant to the DNA Act
    function as ‘genetic fingerprints’ used only for identification purposes,
    arrestees and pretrial detainees have reduced privacy interests in the
    information derived from a DNA sample.”). This Court previously
    compared DNA testing and fingerprints in rejecting a Fourth Amendment
    challenge: “[DNA] tests are akin to taking fingerprints of suspects, which
    may be used to identify perpetrators of past and future crimes or to
    exonerate innocent persons.” In re Leopoldo L., 
    209 Ariz. 249
    , 254 (App. 2004)
    (Timmer, J.). As King explains, “[t]he additional intrusion upon the
    arrestee’s privacy beyond that associated with fingerprinting is not
    significant[.]” 
    569 U.S. at 459
    .
    7             If any of the four factors were to change or become
    inapplicable, the conclusion would likely change.
    21
    STATE v. MITCHAM
    Catlett, J., Concurring
    ¶71            Where a DNA sample differs from a fingerprint is that a DNA
    sample could be used to discover far more personal information about an
    individual. I sympathize with amici’s concern that DNA could be used (or
    abused) to discover a great amount of personal information. As amici puts
    it, “[a]s technology and research continue to advance, DNA analysis will
    allow ever-greater incursions into our privacy.” Amici also contends that
    DNA technology has advanced such that “STR profiles today yield
    information far beyond identity,” and I have no reason to doubt that
    statement. If the State had used the 2015 blood sample to obtain health,
    medical, or other genetic information, the privacy analysis would be much
    different. If the State begins using DNA in an intrusive manner in future
    cases, the analysis must be adjusted to account for the greater privacy
    interests thereby implicated.
    ¶72            But the misuse of DNA is not at issue. Mitcham does not
    suggest the State used the 2015 DNA sample for anything other than a
    limited STR analysis. When that analysis occurred, the State already knew
    the DNA being analyzed belonged to Mitcham. There is no indication the
    State did anything other than use STRs to discover the unique pattern of
    alleles associated with Mitcham’s DNA—that is not private information.
    The State then compared that unique pattern with the unique pattern in
    DNA found at the crime scene. That comparison showed a match, but it
    again revealed nothing private about Mitcham. The limited nature of the
    DNA profile created cuts significantly against any expectation of privacy.
    2.
    ¶73            A search occurs when police draw blood. The U.S. Supreme
    Court has “long recognized that a compelled intrusion into the body for
    blood to be analyzed for alcohol content must be deemed a Fourth
    Amendment search.” Skinner v. Ry. Labor Executives’ Ass’n, 
    489 U.S. 602
    , 616
    (1989) (cleaned up); see also Birchfield v. North Dakota, 
    579 U.S. 438
    , 463 (2016)
    (explaining that although a breath test does not implicate significant
    privacy concerns, “[b]lood tests are a different matter”). Thus, unless an
    exception applies, like exigent circumstances (see Schmerber v. California, 
    384 U.S. 757
     (1966)) or consent (see State v. Valenzuela, 
    239 Ariz. 299
    , 302 ¶ 11
    (2016)), police must obtain a warrant to draw blood.
    ¶74           Mitcham does not challenge the legality of the 2015 blood
    draw—Mitcham expressly consented to that draw. See A.R.S. § 28-1321(A)
    (implied consent law); Carrillo v. Houser, 
    224 Ariz. 463
    , 463 ¶ 1 (2010). In his
    briefing, Mitcham refers to the 2015 blood draw as “a lawfully obtained
    22
    STATE v. MITCHAM
    Catlett, J., Concurring
    blood vial.” In 2015, the State legally came into possession of the blood
    sample later used again in 2018.
    3.
    ¶75           Mitcham also could not have reasonably expected that the
    State was required to destroy his blood sample. In its suppression ruling,
    the superior court observed that Mitcham signed a notice stating that the
    blood he provided “would be destroyed after 90 days if a request for testing
    was not made,” but Mitcham’s blood “was never destroyed.” The notice,
    however, only gave Mitcham the opportunity to have an independent
    laboratory test a “sample” of blood. The notice indicated that the “sample”
    would be destroyed if a request for testing was not received within 90 days.
    ¶76           The notice did not create a reasonable expectation in
    destruction of all of Mitcham’s blood. The text of the notice did not indicate
    that all blood drawn would be destroyed after 90 days; it indicated only
    that one of the samples would go. Moreover, it would not have been
    reasonable for Mitcham to otherwise believe that the State would discard
    evidence of a potential crime (DUI) within 90 days, particularly when
    Mitcham’s prosecution remained pending well after 90 days.
    ¶77           The 2015 analysis of the blood reflected that Mitcham had a
    blood-alcohol level of .242. Once that result returned in May 2015, the
    lawfully obtained blood became evidence of a crime, and the State was
    entitled to maintain possession. Mitcham concedes “that blood evidence
    seized during a DUI, whether consensual or through a warrant, need not
    be returned, as it may be used as evidence in the DUI offense.” Mitcham
    correctly cites A.R.S. § 13-3920(B)(2) for that concession. That statutory
    provision provides that law enforcement must return seized items within
    ten days unless the item “is sought to be used for evidence.” A.R.S. § 13-
    3920(B)(2). When the item is criminal evidence, the statute contains no
    requirement or deadline for returning the item. Mitcham is deemed to
    know the law, and the law allowed the State to keep possession of the 2015
    blood samples during pendency of the DUI prosecution.
    ¶78          Once Mitcham pled guilty to the DUI charges in February
    2016, the State could lawfully keep the 2015 blood samples, and any
    limitation on use based solely on the scope of prior consent dissipated.
    Mitcham provides no support—and I have not independently located
    any—for the proposition that a criminal defendant is entitled to demand
    return or destruction of blood representing the primary evidence in a
    convicted crime. The prime evidence supporting Mitcham’s 2016 DUI
    23
    STATE v. MITCHAM
    Catlett, J., Concurring
    conviction was the 2015 blood sample. Even if Mitcham had a right to
    demand destruction, or limit the use, of the blood prior to conviction or
    upon acquittal, any such right was lost once he pled guilty. Cf. People v.
    King, 
    232 A.D.2d 111
    , 118 (N.Y. App. Div. 1997) (rejecting an argument that
    a blood sample could not be used to investigate a second crime because “a
    defendant does not have a right to the automatic return of property seized
    in any criminal case absent a proper demand or some legal action”). Thus,
    the State maintained lawful possession of Mitcham’s blood sample at the
    time it created the 2018 DNA profile.
    ¶79           Several courts have held that when the government has
    lawful possession of a blood sample stemming from one crime, the
    government can use the sample to investigate another crime. See, e.g., State
    v. Emerson, 
    981 N.E.2d 787
    , 792-93 ¶ 24 (Ohio 2012) (citing cases from eight
    other courts to support the holding that “a person has no reasonable
    expectation of privacy in his or her DNA profile extracted from a lawfully
    obtained DNA sample”); Washington v. State, 
    653 So.2d 362
    , 364 (Fla.1994),
    (“[O]nce [blood] samples were validly obtained, albeit in an unrelated case,
    the police were not restrained from using the samples as evidence in the
    murder case.”); State v. Benefield, 
    103 A.3d 990
    , 100 (Conn. App. Ct. 2014)
    (“[T]here is no constitutional violation of a defendant’s reasonable
    expectation of privacy in bodily fluids that are legally obtained in one
    criminal investigation and subsequently used in an unrelated criminal
    investigation.”); State v. Hauge, 
    79 P.3d 131
    , 145 (Haw. 2003) (“[T]he number
    of investigations in connection with which the [police] tested [defendant’s]
    blood, once the blood is lawfully obtained, is irrelevant to the question
    whether the [police] violated some reasonable expectation of privacy.”).
    ¶80           The foregoing decisions are undoubtedly correct when the
    second use of the blood sample occurs after conviction for the first crime.
    Here, the State did not use the 2015 blood sample until 2018, two years after
    Mitcham pled guilty to DUI.
    4.
    ¶81           There is a fourth factor present—even before the DNA profile,
    the State had probable cause to arrest Mitcham for a serious felony offense
    and reasonable cause to believe the DNA sample would help confirm (or
    exclude) Mitcham as the source of DNA at the crime scene. Returning to
    the fingerprint analogy, the U.S. Supreme Court has explained that an
    individual can be detained for fingerprinting “if there is reasonable
    suspicion that the suspect has committed a criminal act, [and] if there is a
    reasonable basis for believing that fingerprinting will establish or negate
    24
    STATE v. MITCHAM
    Catlett, J., Concurring
    the suspect’s connection with that crime.” Hayes v. Florida, 
    470 U.S. 811
    , 817
    (1985); cf. A.R.S. § 13-3905 (allowing courts, on less than probable cause, to
    authorize police to detain an individual to obtain biological samples for
    identification purposes).
    ¶82            In Mario W., the court, citing Hayes, thought it relevant that
    the State wanted to analyze DNA without “even reasonably suspect[ing]
    that a juvenile committed another offense for which the DNA profile might
    provide investigative assistance.” 
    230 Ariz. at
    125 ¶ 9. And the court
    suggested its analysis would be different if there was probable cause or
    reasonable suspicion to believe an individual committed an uncharged
    offense. 
    Id.
     at 129 ¶ 31.
    ¶83           Here, there was probable cause that Mitcham committed
    murder. As the majority explains, “the evidence independent of that DNA
    profile provided sufficient probable cause to authorize Mitcham’s arrest.”
    Maj. Op. ¶ 46. At oral argument, Mitcham conceded that, based on a
    familial DNA analysis and the location of their residences, the State had
    probable cause to arrest both Mitcham and his brother. Id. ¶ 45. It is clear,
    therefore, that the State could arrest Mitcham first based on his prior arrest
    record and the location of his home. Cf. Maryland v. Pringle, 
    540 U.S. 366
    ,
    372—73 (2003) (officer performing traffic stop had probable cause to arrest
    all three occupants of vehicle after cocaine was found in backseat of car
    behind armrest).
    ¶84           There was also reasonable cause to believe a DNA profile
    would provide investigative assistance by supporting or negating
    Mitcham’s presence at the murder scene. Upon Mitcham’s arrest, Arizona
    law permitted the State to perform a buccal swab and analyze the resulting
    DNA. See A.R.S. § 13-610(K). No one in Mitcham’s position would think
    the State, upon obtaining probable cause to arrest for a serious felony
    offense, could not first analyze blood it already lawfully possessed to confirm
    or negate a connection to the murder scene. Though we now know the
    results of the DNA analysis in this case, and thus have the benefit of
    hindsight, there can be little doubt that Mitcham would have preferred the
    DNA analysis to being arrested if the analysis would have negated his
    presence at the murder scene. Thus, unlike in Mario W., obtaining a DNA
    profile had an investigative (and potentially exonerating) purpose.
    5.
    ¶85          In sum, Mitcham did not have a reasonable expectation of
    privacy in 2018 in (1) the non-coding regions of DNA contained (2) in a
    25
    STATE v. MITCHAM
    Catlett, J., Concurring
    blood sample lawfully obtained in 2015 and (3) then lawfully kept
    following his 2016 conviction for DUI when (4) the State had probable cause
    to believe he committed murder and reasonable cause to believe the sample
    would help confirm or negate his presence at the crime scene.
    Consequently, creating a DNA profile in 2018 was not a “search” requiring
    a warrant.
    IV.
