    OPINION
    By the Court, GIBBONS, J.:
    The Fourth Amendment to the United States Constitution and
    Article I, Section 18 of the Nevada Constitution provide that the people
    possess an inviolable right against unreasonable searches and seizures.
    Under both provisions, warrantless searches are per se unreasonable
    subject to a few specific exceptions. One such exception is the consent of a
    third party who has authority over the premises or effects to be searched.
    Though Nevada's jurisprudence has• delineated the basic
    principles governing consent as an exception to the warrant requirement,
    this case presents a question concerning that exception that our caselaw
    does not fully address: how does a person's living arrangement within a
    third party's residence affect that third party's legal authority to consent to
    a search of the other person's living space? Additionally, can law
    enforcement officers rely upon the consent of a third party to search a room
    within a residence without asking about the living arrangements within
    that residence?
    Looking to federal caselaw, we conclude that law enforcement
    officers cannot justify a warrantless search of a bedroom inside a home by
    pointing to the consent of a third party when the third party did not have
    authority to consent and officers have little or no information about that
    third party's authority over the bedroom. Accordingly, we instruct law
    enforcement officers to make sufficient inquiries about the parties' living
    arrangements and the third party's authority over them before conducting
    a warrantless search.

    FACTS AND PROCEDURAL HISTORY
    On Wednesday, January 7, 2016, Gertrude Green's vehicle was
    rear-ended by a truck while waiting at a traffic light on her drive home from
    work, and she suffered a whiplash injury. The driver of the truck drove
    away after striking Green's car. Green and one witness told first responders
    they believed the driver was a man.
    In the debris field on the road, a Nevada Highway Patrol
    trooper found a license plate that did not belong to Green's car. The trooper
    ran the plate through dispatch and discovered the plate belonged to a truck
    registered to Andrew Lastine. Due to concurrent jurisdiction in the area,
    Washoe County Sheriffs Deputy Francisco Gamboa headed to the address
    listed on the truck's registration.
    When he arrived at the address at about 6 p.m., Deputy
    Gamboa observed a small truck in the driveway with front-end damage and
    smoke or steam coming from the engine compartment. The license plate
    matched the one found at the scene of the Green accident. He also saw
    footprints in the snow leading from the truck to the house located at the
    address. Based on these observations, Deputy Gamboa initiated a "knock
    and talk" investigation.'
    Robert Lastine (Robert) answered the door. Deputy Gamboa
    identified himself after Robert stepped outside. He then informed Robert
    about the Green accident and that the license plate found at the scene of
    the Green accident matched the license plate on the truck. Deputy Gamboa
    'In a "knock and talk" investigation, police officers "approach the
    front door of a residence," knock on the door, and seek "to speak to an
    occupant for the purpose of gathering evidence." Florida v. Jardines, 
    569 U.S. 1
    , 21 (2013) (Alito, J., dissenting).
    COURT OF APPEALS
    OF
    NEVADA

    asked Robert who owned the truck, and Robert told him that his nephew,
    Andrew Lastine, owned the truck. Robert also told Deputy Gamboa that
    Lastine was probably in "the back bedroom" of the house. At some point
    later, Deputy Gamboa asked for permission to enter Robert's house to "find
    the owner of the truck." Robert apparently said, "go get him."
    As a safety precaution, Deputy Gamboa waited for a back-up
    deputy, Deputy Martin Obos, to arrive at the residence before entering the
    house. He did not attempt to secure a telephonic search warrant or
    ascertain Lastine's physical condition while he waited. When Deputy Obos
    arrived, both he and Deputy Gamboa walked into the house, and Robert
    guided them to a hallway and pointed to a door indicating it led into the
    back bedroom where he suggested they might find Lastine.
    According to Deputy Gamboa, he and Deputy Obos stood at the
    bedroom door, did not knock, but announced "police, sheriffs office." After
    no response, the deputies pushed the door open. The bedroom was dark,
    but Deputy Gamboa testified he could make out a bed directly in front of
    the doorway with a person, later identified as Lastine, on it under a blanket
    They ordered Lastine to show his hands, but he refused. The deputies
    entered the bedroom, removed the blanket covering Lastine, and placed him
    in handcuffs. Inside the bedroom, the deputies saw a pair of tennis shoes
    with snow and mud on them and snowy, muddy footprints. The deputies
    removed Lastine from the bedroom and placed him on a couch in the living
    room.
    Later, Nevada Highway Patrol Trooper Alyssa Howald arrived
    at the residence from the scene of the Green accident. She met with Deputy
    Gamboa outside the house, and he told her that he and Deputy Obos had a
    suspect in custody inside the house. Deputy Gamboa explained that the
    COURT OF APPEALS
    OF
    NEVADA

    footprints that led in the snow from near the driver's side door of the truck
    to a door at that residence matched the tread on a pair of shoes he found in
    Lastine's room, where Lastine was located.
    Trooper Howald entered the house and placed Lastine under
    arrest. She performed a search of Lastine's person incident to that arrest
    and found a set of keys in his pants pocket. Without more, Trooper Howald
    used a key from the set to open the locked truck and started the truck's
    engine.
    Trooper Howald transported Lastine to the Washoe County jail.
    Though Trooper Howald did not ask him any questions, Lastine made
    several spontaneous remarks, including stating he was an "idiot and that's
    all that matters."
    Lastine was charged with one count of leaving the scene of an
    accident involving personal injury. He moved to suppress the evidence
    gathered as a result of the deputies' warrantless entry into his bedroom and
    the trooper's warrantless entry into his vehicle. The district court denied
    most of Lastine's motion, granting only his request to suppress the fact that
    the keys Trooper Howald found in his pocket opened and started the truck.
    Lastine's case proceeded to a jury trial. The jury found him
    guilty of leaving the scene of an accident involving personal injury. He was
    sentenced to serve three to ten years in prison. This appeal follows.
    ANALYSIS
    Lastine argues that the district court erred by denying in part
    his motion to suppress. In particular, he argues that Robert did not have
    actual or apparent authority to consent to a search of Lastine's bedroom
    because that bedroom "was not a commonly shared area." Further, he

    NEVADA

    argues that, given the totality of the circumstances, no exigency existed to
    justify the deputies' warrantless entry into his bedroom.
    The Fourth Amendment generally prohibits the warrantless
    entry of a person's home. See Payton v. New York, 
    445 U.S. 573
    , 585-86
    (1980). Warrantless searches are per se unreasonable, unless an
    "established and well-delineated exception[ applies.        State v. Lloyd, 
    129 Nev. 739
    , 743, 
    312 P.3d 467
    , 469 (2013) (quoting Katz v. United States, 
    389 U.S. 347
    , 357 (1967)). One exception to the warrant requirement "is the
    valid consent of a third party who possesses actual authority over or other
    sufficient relationship to the premises or effects sought to be inspected."
    State v. Taylor, 
    114 Nev. 1071
    , 1079, 
    968 P.2d 315
    , 321 (1998) (citing United
    States v. Matlock, 
    415 U.S. 164
    , 171 (1974)). Even if it later turns out that
    the third party did not have actual authority over the area searched, the
    search may still be valid under the apparent authority doctrine if the law
    enforcement officers reasonably believed, based upon the facts available to
    them at the moment of the warrantless search, the consenting party had
    actual authority. See 
    id. at 1080,
    968 P.2d at 322.
    The burden of establishing actual or apparent authority rests
    with the State. See Illinois v. Rodriguez, 
    497 U.S. 177
    , 181 (1990); see also
    United States v. Arreguin, 
    735 F.3d 1168
    , 1174 (9th Cr. 2013) ("Mhe
    government has the burden of establishing the effectiveness of a third
    party's consent to a search of a defendant's property."). Because review of
    a district court's determinations concerning "authority to consent to a
    search requires consideration of both factual" and legal issues, "we review
    de novo the district court's decisions regarding authority to consent."
    
    Taylor, 114 Nev. at 1078
    , 968 P.2d at 321. In so doing, "this court treats the

    OF

    district court's findings of fact deferentially. . . ." McMorran v. State, 
    118 Nev. 379
    , 383, 
    46 P.3d 81
    , 84 (2002).
    Did Robert have authority to consent to a search of Lastine's bedroom?
    In the proceedings below, the district court concluded that
    Robert was "the actual and apparent owner of the home and his authority
    to consent to a search included [Lastine's1 bedroom." The court did not
    expressly parse out the legal distinctions between actual and apparent
    authority and the elements of each in its analysis. See 
    Rodriguez, 497 U.S. at 181-83
    . We do so now, turning first to actual authority.
    Actual authority
    We first address whether Robert had actual authority to
    consent to a search of Lastine's bedroom. Actual authority to consent to a
    search is a legal condition that is wholly separate from and independent of
    what a particular law enforcement officer believes about a third party's
    authority over a premises or object to be searched.       See 
    id. at 181-82;
                       
    Matlock, 415 U.S. at 171
    n.7 (noting that common authority is based "on
    mutual use of the property by persons generally having joint access or
    control for most purposes"). "Actual authority is proved (1) where defendant
    and a third party have mutual use of and joint access to or control over the
    property at issue, or (2) where defendant assumes the risk that the third
    party might consent to a search of the property." 
    Taylor, 114 Nev. at 1079
    ,
    968 P.2d at 321. "Actual authority does not require an ownership interest
    in the property by the third party and does not require the actual owner's
    presence at the time of the search." 
    Id. (citations omitted).
                                   Lastine argues that his bedroom was not a commonly shared
    area. He asserts that while Robert had actual authority to consent to the
    deputies' search of the common areas inside the house, Robert lacked actual
    COURT OF APPEALS
    OF
    NEVADA
    7
    (0) 1947R
    authority to consent to a search inside Lastine's bedroom, which was a
    separate room of the house.
    The State counters that because Robert owned and lived in the
    house, he had actual authority to consent to a search of any room within
    that house, including Lastine's bedroom. We disagree with the State.
    The Nevada Supreme Court addressed a third-party
    cohabitant's consent to a search within a residence in Casteel v. State.
    There, Casteel appealed from the district court's denial of his motion to
    suppress evidence the police discovered when they searched his apartment
    based on his live-in girlfriend's 
    consent. 122 Nev. at 360
    , 131 P.3d at 3.
    The supreme court considered, in relevant part, whether
    Casteel's live-in girlfriend had authority to consent to a search of their
    shared apartment and Casteel's gym bag, which was inside a closet in the
    apartment. 
    Id. at 359-61,
    131 P.3d at 2-4. It observed that "[a] warrantless
    search is valid if the police acquire consent from a cohabitant who possesses
    common authority over the property to be searched." Id. at 
    360, 131 P.3d at 3
    (emphasis added) (citing 
    Rodriguez, 497 U.S. at 181
    ). The court concluded
    that Casteel's live-in girlfriend "clearly consented to the search and had
    equal control over the apartment." 
    Id. In this
    case, Robert and Lastine both lived in the residence.
    However, unlike in Casteel, they did not cohabit, "share," or possess "equal
    control over" Lastine's bedroom Instead, Robert ceded most of his control
    of the bedroom to Lastine, and Lastine paid rent for the use of the bedroom.
    Consequently, Robert was in effect Lastine's landlord.
    If we view Robert as Lastine's landlord, instead of or in addition
    to being a cohabitant of the house, his access to Lastine's room would be
    further limited. See United States v. Warner, 
    843 F.2d 401
    , 403 (9th Cir.
    COURT OF APPEALS
    OF
    NEVADA
    8
    (0) 19475
    1988) (recognizing landlords' lack of authority to consent to a search of a
    tenant's apartment) Third parties such as landlords with access to an area
    only have actual authority to consent to a search of that area when they
    reserve a right of access "for most purposes," instead of a limited right of
    access to conduct repairs or maintenance, or engage in any other "narrowly
    prescribed" set of activities. See id.; see also United States v. Kim, 
    105 F.3d 1579
    , 1582 (9th Cir. 1997).
    Here, Robert did not reserve a broad right of access "for most
    purposes" to Lastine's bedroom. Robert testified at the suppression hearing
    that he built the back bedroom as an addition to the modular home for the
    purpose of permitting others to live there. The room was attached to the
    home and shared a common roofline, but it was built on a separate
    foundation for all four of its walls. Robert also testified that he did not
    spend any time in the back bedroom and he did not enter the bedroom freely
    as the door was always closed and he knocked before entering.
    Consequently, Robert had only limited access to Lastine's bedroom and did
    not have actual authority to consent to the search of that room.
    Still, if a defendant assumes the risk that some third party,
    such as a landlord, with limited access to the searched property, "will at
    times exceed the scope of authorized access," United States v. Sledge, 
    650 F.2d 1075
    , 1080 n.10 (9th Cir. 1981), then that third party will have
    "[actual] authority to consent to [a] search"    
    Kim, 105 F.3d at 1582
    . A
    defendant generally assumes the risk when he cedes control of his property
    to another. See 
    Taylor, 114 Nev. at 1079
    , 968 P.2d at 321 (concluding that
    Taylor gave control of his suitcase to a third party and assumed the risk she
    might allow law enforcement to search it when the suitcase was checked in
    COURT OF APPEALS
    OF
    NEVADA
    9
    (0) 19473
    the third party's name, she kept the baggage claim ticket, and Taylor did
    not remain with the third party while they were in the airport together).
    The State avers on appeal that Robert also possessed actual
    authority because Lastine assumed the risk that Robert would "consent to
    a search of his own house." The State did not argue this alternative below,
    and therefore it waived this argument. See Emmons v. State, 
    107 Nev. 53
    ,
    60-61, 
    807 P.2d 718
    , 723 (1991). But even if the court considered it on the
    merits, it fails. The State contends that Lastine failed to show he had
    exclusive control over the room or the details about the living arrangements,
    yet the evidence reveals that Lastine had a lock on the interior door and
    had closed the door—so Lastine took steps to protect his privacy interest.
    Cf. 
    Taylor, 114 Nev. at 1079
    , 968 P.2d at 321. Moreover, the State's
    assumption-of-the-risk argument attempts to shift the burden onto Lastine
    to prove he possessed constitutionally protected privacy interests in the
    bedroom. At the outset, we reiterate that the burden of proving that a third
    party had authority to consent to a warrantless search rests with the State.
    See 
    Rodriguez, 497 U.S. at 181
    . The defendant does not have the burden to
    disprove the third party's authority. See 
    id. Here, the
    State did not provide any proof that Robert entered
    Lastine's bedroom unannounced or otherwise exceeded his limited access to
    the bedroom such that Lastine assumed the risk that Robert would exceed
    his authorized access to Lastine's bedroom. Robert's testimony at the
    suppression hearing suggested the opposite—Lastine assumed no such risk,
    as Robert characterized the bedroom as Lastine's space that he rented, and
    the door was always closed. Additionally, the district court did not make
    any findings that Lastine assumed the risk. We conclude the State failed
    to meet its burden to prove that Robert possessed actual authority to
    COURT OF APPEALS
    OF
    NEVADA
    10
    10) 19473
    consent to a search of Lastine's bedroom. We turn now to apparent
    authority.
    Apparent authority
    The State argues that even if Robert did not have actual
    authority to consent to a search of Lastine's bedroom, Robert had apparent
    authority to authorize the search. Lastine counters that the deputies did
    not have sufficient facts available to them to justify the search based on the
    doctrine of apparent authority. We agree with Lastine.
    Apparent authority is a misnomer of sorts. A third party does
    not possess apparent authority; rather, apparent authority exists when the
    law enforcement officers who conducted a warrantless search or seizure
    based on a third party's consent reasonably believed that the third party
    had actual authority to give consent. See 
    id. at 183.
    In this way, apparent
    authority goes to the key assurance of the Fourth Amendment—that no
    search will occur that is "unreasonable," not that no imperfect searches will
    occur. See 
    id. (emphasis added).
    Thus, the apparent authority doctrine
    permits warrantless searches and seizures based upon the consent of a third
    party who lacks actual authority to consent so long as the law enforcement
    officers who relied upon the third party's consent acted reasonably given the
    circumstances available at the time of the search or seizure. See 
    id. at 187-
                       89.
    To determine whether law enforcement officers possessed an
    objectively reasonable belief that a third party had authority to consent to
    a search of a certain area, we assess the reasonableness of their belief by
    considering "the facts available to [them] at the moment." 
    Arreguin, 735 F.3d at 1175
    (quoting 
    Rodriguez, 497 U.S. at 188
    ). Again, the State has the
    burden to show the officers' belief concerning the third party's authority to
    consent to a search was reasonable concerning "each specific area searched."
    COURT OF APPEALS
    OF
    NEVADA
    11
    (0) 194711
    
    Id. (brackets omitted).
    When law enforcement officers proceed to search an
    area based on the consent of a third party "in a state of near-ignorance"
    without obtaining sufficient information about the third party's authority,
    we cannot conclude they possessed an objectively reasonable belief that the
    third party had authority to consent to a search. 
    Id. at 1176.
                                   For example, consider the facts of Arreguin as they are similar
    to the present case. There, nine law enforcement officers knocked on the
    door of a house they suspected had been used for illegal drug-related
    activity. 
    Id. at 1171-72.
    A man answered the door. 
    Id. at 1172.
    The officers
    knew little about this man, the various rooms or areas inside the house, or
    the "nature and extent of [the man's] connection to those separate areas."
    
    Id. at 1175.
    Yet, despite their "near-ignorance," 
    id. at 1176,
    the officers
    relied upon that man's consent to conduct a thorough search of a number of
    rooms inside the house, including the garage. 
    Id. at 1172-73.
    Ultimately,
    they learned that the man was a visitor at the home and another occupant,
    whom they saw but did not question, owned the house. 
    Id. at 1173.
                                    The United States Court of Appeals for the Ninth Circuit
    concluded that the officers acted unreasonably by presuming the man who
    answered the door had authority to consent to their request to search
    without further inquiry. 
    Id. at 1177.
    The court held that "[t]he failure to
    inquire properly weighs against the government, not [the defendant],
    because the police are simply 'not allowed to proceed on the theory that
    ignorance is bliss." 
    Id. (quoting United
    States v. Dearing, 
    9 F.3d 1428
    , 1430
    (9th Cir. 1993)).
    We agree with the Ninth Circuit's approach. Law enforcement
    officers cannot use the apparent authority doctrine to justify a warrantless
    search when they fail to make a sufficient inquiry into the consenting
    COURT OF APPEALS
    OF
    NEVADA
    12
    (0) 194713 400,
    party's "use, access, or control over" the area to be searched.      
    Id. We carefully
    scrutinize searches that occur in private areas such as bedrooms
    as "Mlle Fourth Amendment's protection is at its zenith within the
    home. . . ." Thompson v. Rahr, 
    885 F.3d 582
    , 589 (9th Cir. 2018) (citing
    
    Payton, 445 U.S. at 589-90
    ). Law enforcement officers may not "always
    accept a person's invitation to enter [thel premises." 
    Rodriguez, 497 U.S. at 188
    (alteration to the original). When the facts available to and known by
    the officers are insufficient to establish a reasonable belief that the third
    party inviting the officers into the home to conduct a search has the
    authority to do so, "then warrantless entry without further inquiry is
    unlawful unless authority actually exists." 
    Id. at 188-89.
                                   In this case, the district court did not squarely address whether
    either Deputy Gamboa or Deputy Obos (or both) possessed an objectively
    reasonable belief based upon the totality of the circumstances available to
    them that Robert had authority to consent to a search of Lastine's bedroom.
    The court only stated that Robert was the apparent owner of the home.
    Neither Deputy Gamboa nor Deputy Obos sufficiently inquired
    into Lastine's living arrangement. Deputy Gamboa knew that Robert lived
    in the house, Robert was Lastine's uncle, Lastine owned the truck outside
    the house, and Lastine may have been in the back bedroom of the house.
    Deputy Gamboa did not ask Robert about the ownership of the house or any
    rental arrangements regarding the rooms in the house. And Deputy
    Gamboa had time to ask Robert additional questions to gather relevant
    information about Lastine's living arrangement as he waited for Deputy
    Obos to arrive, but did not do so.
    When faced with a situation like this in which the suspect in a
    crime is located within a private area of a home such as a bedroom—not in

    a common area—and law enforcement officers choose to enter the private
    area without the consent of the person occupying the private area, but with
    the consent of a third party, they need to ensure the third party has the
    authority to allow the intrusion. The objective is to determine if the third
    party has the actual authority to consent to the search as discussed earlier
    in this opinion. Asking the third party about his control over the private
    area is the first step. Does the third party have primary control over or
    mutual use of the private area to be searched? Or is the area controlled and
    used primarily by the person suspected of the crime? If it is used primarily
    by the suspect, then further inquiries are needed to determine if it is a near
    exclusive use such as by a renter or tenant. Conducting such inquires is an
    indication that officers are acting in good faith in attempting to comply with
    the law when they do not choose to seek a search warrant. See United States
    v. Leon, 
    468 U.S. 897
    , 907-08, 919-20 (1984) (recognizing policy of limiting
    the extent of the exclusionary rule when police act in "objective good faith"). 2
    Such efforts could justify the application of the apparent authority doctrine
    if actual authority did not in fact exist.
    Based on what the deputies knew about Lastine's living
    arrangement inside Robert's house, it appears they presumed that, because
    Robert answered the door, lived in the house, and was Lastine's older
    relative, Robert had authority to consent to the search of Lastine's bedroom.
    As in Arreguin, the deputies' presumption about Robert's authority based
    2 We  note that the better practice is to obtain a search warrant when
    practical, and here, Deputy Gamboa had an opportunity to seek a telephonic
    search warrant while he waited for Deputy Obos to arrive. See 
    Leon, 468 U.S. at 920-21
    (stating that generally there is no illegal police action "when
    an officer acting with objective good faith has obtained a search warrant
    from a judge or magistrate and acted within its scope").

    on the information they gathered was unreasonable. Had the deputies
    conducted even a brief fact-finding inquiry, they would have learned Robert
    was the owner, but he did not have actual authority as: (1) Robert built the
    back bedroom in which Lastine lived as an addition to provide a separate
    living space; (2) although Lastine was an adult relative, he was also a
    paying tenant and could come and go as he pleased and have guests over
    without Robert's knowledge or authorization; and (3) the room had its own
    doors leading in and out of the house, there was a lock on the interior door,
    that door was normally kept closed, and Robert did not enter without
    knocking. 3 However, because the deputies failed to make any inquiries
    about the use and control of the bedroom, they did not have a sufficient basis
    to believe Robert had primary or even mutual use, access, or control over
    the bedroom. Neither Robert's occupancy of the house, nor his status as
    Lastine's older relative, without more, was enough to support the deputies'
    belief Robert had authority to consent to a search of Lastine's bedroom.
    Thus, under the totality of the circumstances in this case, we conclude the
    deputies did not gather sufficient information to form an objectively
    reasonable belief that Robert had authority to consent to a search of
    Lastine's separate bedroom.
    Did emergency circumstances justify entry into Lastine's bedroom?
    Lastine argues that no exigency existed to justify the deputies'
    warrantless entry into his bedroom. The State argued below in its brief that
    probable cause to arrest and officer safety justified the warrantless entry
    into the bedroom. The State, however, has abandoned these arguments on
    appeal and now only argues that the emergency doctrine justified entry into

    Lastine's bedroom as Deputy Gamboa was concerned for Lastine's physical
    well-being. The district court made no findings as to whether an officer
    safety exigency or an emergency existed.      See Hannon v. State, 
    125 Nev. 142
    , 145-46, 
    207 P.3d 344
    , 346 (2009) ("Emergencies. . . are analytically
    distinct from other exigent circumstances.").
    Although the State did not clearly present the emergency
    doctrine as an argument below, 4 we will review the argument de novo and
    determine whether an emergency justified the deputies' entry into Lastine's
    bedroom. See 
    id. at 145,
    207 P.3d at 346. The subjective intent of the
    deputies is not relevant as we look to see if they possessed "an objectively
    reasonable basis to believe that there was an immediate need to protect the
    lives or safety of themselves or others." 
    Id. at 147,
    207 P.3d at 347.
    The State argues Deputy Gamboa was concerned for Lastine's
    well-being because there had been a major car accident with damage to
    Lastine's truck. The State cites to Koza v. State, which describes the
    emergency doctrine as an urgent need to enter the private premises not to
    arrest or search, but to protect life or property or investigate a "substantial
    4Although  Deputy Gamboa answered affirmatively when prompted at
    the suppression hearing whether he was potentially concerned for Lastine's
    well-being, there was no other evidence presented that this potential
    concern led to the warrantless entry into Lastine's bedroom or that the
    entry was objectively reasonable. Furthermore, in its argument below, the
    State characterized the situation as a potential hypothetical (as no evidence
    or legal authority was presented) that the delay that would be caused by
    the telephonic search warrant process might have adversely affected the
    well-being of Lastine. But on appeal, the State recites in its brief the factual
    reason for the entry into the bedroom as, "Andrew refused to show his
    hands, so deputies entered the room. Robert Lastine [later] thought
    Andrew needed medical treatment."

    threat of imminent danger." 
    100 Nev. 245

    681 P.2d 44
    , 48 (1984)
    (quoting Banks v. State, 
    94 Nev. 90
    , 97, 
    575 P.2d 592
    , 596 (1978)).
    When viewed objectively, the facts do not demonstrate a
    reasonable basis to believe Lastine was in imminent danger. Air bags were
    not activated at the time of the collision, and Lastine immediately drove
    from the scene of the accident to his home. Damage was observed to the
    exterior of his vehicle but not to the interior. There was no blood in or on
    his truck, and no blood was found in or on the home. Also, the deputies'
    actions were consistent with a criminal investigation and not the duty to
    protect life. Deputy Gamboa did not immediately enter the home or the
    bedroom to check on the welfare of Lastine. Instead, he waited for Deputy
    Obos to arrive and assist with the search. 5 Also, he did not ask Robert to
    check on Lastine's well-being at any time. Deputy Gamboa could not recall
    if paramedics later responded to the scene. He recalled that the fire
    department was dispatched, but only to check on the smoking vehicle.
    Moreover, when the deputies attempted to initiate
    communication with Lastine at his bedroom door, they did not ask if he was
    injured. And, when they finally entered the room, it was a direct reaction
    to both Lastine's verbal and nonverbal refusal to show his hands, not
    because Lastine had been nonresponsive. The deputies then immediately
    searched, handcuffed, and took Lastine into their physical custody. It was
    only later when Robert expressed concern over Lastine's well-being that
    paramedics were summoned. In fact, Robert testified that Deputy Gamboa
    We note this fact undermines the argument raised in the
    5
    hypothetical posed by the State during the suppression hearing because
    Deputy Gamboa had adequate time during this interval to seek a telephonic
    search warrant. See NRS 179.045.

    did not ask for consent to enter the home to check on the well-being of
    Lastine. Therefore, the totality of the circumstances does not suggest an
    objectively reasonable basis to believe an immediate entry was needed to
    protect Lastine. See 
    id. Having concluded
    that Robert did not possess actual authority
    to consent to the deputies' entry into Lastine's bedroom, the deputies did
    not have an objectively reasonable belief that Robert had such authority,
    and no exigent or emergency circumstances existed, we further conclude the
    deputies' warrantless search was constitutionally unreasonable. Therefore,
    the district court erred by denying the motion to suppress all evidence
    obtained from the deputies' warrantless entry into Lastine's bedroom. See
    United States v. Pulliam, 
    405 F.3d 782
    , 785 (9th Cir. 2005) ("[T]he
    exclusionary rule reaches not only primary evidence obtained as a direct
    result of an illegal search or seizure, but also evidence later discovered and
    found to be derivative of an illegality or fruit of the poisonous tree." (internal
    quotation marks omitted)).
    Was the district court's error in denying in part Lastine's motion to suppress
    harmless beyond a reasonable doubt?
    The State argues that if the district court erred by denying in
    part Lastine's motion to suppress, the error was harmless beyond a
    reasonable doubt, as overwhelming evidence supports the conviction. We
    disagree.
    Where the issue has been preserved for appeal, we can only
    affirm a ruling containing constitutional errors if we are "able to declare a
    belief that [the errors were] harmless beyond a reasonable doubt."
    Chapman v. California, 
    386 U.S. 18
    , 24 (1967); see also Medina v. State, 
    122 Nev. 346
    , 355, 
    143 P.3d 471
    , 476-77 (2006). "Under this standard, reversal
    is not required if the State [can] show beyond a reasonable doubt that the
    COURT OF APPEALS
    OF

    error complained of did not contribute to the verdict obtained." 
    Medina, 122 Nev. at 355
    , 143 P.3d at 477 (internal quotation marks and citations
    omitted). The State does not meet this burden.
    Important evidence the State presented at trial to prove that
    Lastine was the person who committed the crime came from the deputies'
    illegal entry into Lastine's bedroom. We cannot say beyond a reasonable
    doubtS that admission of this evidence did not contribute to the verdict.
    Therefore, we conclude the State has not demonstrated that the district
    court's erroneous decision to deny the suppression of this evidence was
    harmless beyond a reasonable doubt.
    CONCLUSION
    Law enforcement officers may conduct a warrantless search if
    a third party with common authority over an area consents to that search.
    A warrantless search based upon third-party consent is lawful so long as
    the third party has actual authority to consent or the law enforcement
    officers formed an objectively reasonable belief, based upon the facts
    available to them, that the third party had authority to consent.
    Law enforcement officers cannot justify a warrantless search of
    a bedroom inside a home by pointing to the consent of a third party when
    the officers have little to no information about that third party's authority
    in the home. Rather, law enforcement officers should gather sufficient
    information about the living arrangements inside the home to establish an
    objectively reasonable belief that the third party has authority to consent to
    a search therein before proceeding with that search without a warrant, lest
    they risk the search being deemed unconstitutional. To this end, we
    encourage law enforcement officers to seek a warrant before conducting a
    search if practical, even when an exception to the warrant requirement
    seems to exist.
