    SUMMARY
    August 5, 2021
    2021COA104
    No. 19CA1772, People v. Stone — Constitutional Law — Fourth
    Amendment — Searches and Seizures — Warrantless Search —
    Consent Exception
    A division of the court of appeals considers for the first time
    whether an occupant’s consent to a law enforcement officer’s entry
    into his or her home extends to the officer’s re-entry into the home
    after the officer has briefly left it. The division concludes that,
    where the initial entry and the re-entry are closely related in time
    and purpose, the initial consent extends to the subsequent re-entry.

    Philip J. Weiser, Attorney General, Rebecca A. Adams, Senior Assistant
    Attorney General, Denver, Colorado, for Plaintiff-Appellee
    Scott Poland, Alternate Defense Counsel, Lakewood, Colorado, for Defendant-
    Appellant
    *Sitting by assignment of the Chief Justice under provisions of Colo. Const. art.
    VI, § 5(3), and § 24-51-1105, C.R.S. 2020.
    ¶1    The Fourth Amendment to the United States Constitution and
    article II, section 7 of the Colorado Constitution protect individuals
    against unreasonable searches and seizures. Unless one of the
    exceptions to the search warrant requirement applies, law
    enforcement officers are barred from entering a person’s home
    without a warrant. One of those exceptions applies when a person
    with authority over the home freely and voluntarily consents to the
    law enforcement officer’s entry into the home. This case addresses
    the scope of that consent.
    ¶2    We consider in this case a novel issue of Colorado law —
    whether an occupant’s consent to a law enforcement officer’s entry
    into the occupant’s home extends to the officer’s re-entry into the
    home after the officer has briefly left it, where the initial entry and
    the re-entry are closely related in time and purpose, and the
    occupant did not revoke or limit the initial consent. We conclude
    that, under these circumstances, the occupant’s initial consent
    extends to the officer’s re-entry into the home.
    ¶3    Adrienne Marie Stone appeals her judgment of conviction
    based on her contention that the court erred by admitting evidence
    obtained during an illegal search of her house. We affirm.
    1
    I.   Background Facts
    A.    The Officers’ Entry into Stone and N.M.’s House
    ¶4    Sergeant Betsy Westbrook of the Arvada Police Department
    responded to a report of a disturbance involving a seventeen-year-
    old, N.M., who said that Stone, his mother, had threatened him
    with a knife. Upon arriving at Stone and N.M.’s house, Westbrook
    spoke with N.M.’s sister, M.M., who was standing in front of the
    house. M.M. told Westbrook that, three days earlier, Stone had
    threatened N.M. with a knife. M.M. said that she was worried for
    N.M.’s safety because Stone was headed to the house, was very
    angry with N.M., and had told him to “pray for his life.”
    ¶5    While speaking with M.M., Westbrook noticed that a young
    man holding a baby briefly opened the front door of the house and
    then closed it. Suspecting that the young man was N.M.,
    Westbrook knocked on the door. N.M. opened the door, agreed to
    speak with Westbrook, and identified himself. Westbrook asked
    N.M. whether she could speak with him inside the house. N.M.
    responded affirmatively and expressly invited her inside.
    ¶6    Upon entering the house, Westbrook observed a stairway filled
    with boxes, clothing, and other items that “block[ed] free
    2
    movement.” In addition, she saw that the kitchen and living room
    were cluttered and that a young child was “crawling over” a baby
    gate set up between the living room and kitchen. Westbrook said
    that the child “could just climb up on different things and get over
    [the baby gate] easily.”
    ¶7    N.M. led Westbrook into the kitchen, where he showed her a
    knife that he said Stone had used to threaten him. Westbrook took
    two photographs of the knife with her cell phone. She then left the
    house to retrieve her department-issued camera from her car so she
    could take better pictures of the interior of the house than she
    could with the cell phone.
    ¶8    As she stepped outside the house, Westbrook saw that Stone
    had arrived. Stone was upset that a police officer and M.M. were at
    the house. Stone also appeared to be yelling at a neighbor.
    Because the situation involving Stone was “rapidly unfolding,”
    Westbrook re-entered the house without her camera.
    ¶9    Blaine Engdahl, a resource officer at N.M.’s school, also
    arrived at the house. After speaking briefly with M.M., Engdahl saw
    N.M. at the front door. He entered the house with N.M. and, like
    Westbrook, observed the clutter inside the house. Engdahl noted
    3
    that “[t]he movement through the house was by pathways through
    the clutter,” which extended “up the stairs to the second floor.”
    ¶ 10   After Westbrook and Engdahl spoke with N.M. and saw the
    interior of the house, they returned outside, where Westbrook
    “made the decision to contact Jefferson County protection services”
    about the children. A caseworker from protection services, Misty
    Bogle, arrived and entered the house. Upon evaluating the
    condition of the house, Bogle concluded it was unfit for children
    and that the children needed to be removed from it.
    ¶ 11   While Bogle, Westbrook, and N.M. gathered the children’s
    belongings, a code enforcement officer, Nicole Miller, and another
    police officer, Devoney Cooke, entered the house. Cooke
    photographed the interior of the house while she, Westbrook, and
    Miller walked through it together. Over the next couple of hours,
    other law enforcement officers also entered the house.
    ¶ 12   Stone was arrested and charged with one count of felony
    menacing, seven counts of child abuse, and one count of violation
    of a protection order that the neighbor had obtained against her.
    One of the counts of child abuse was later dismissed because N.M.
    was not under the age of sixteen at the time of the alleged abuse.
    4
    B.    The Suppression Hearing and the Trial
    ¶ 13   Stone filed a pretrial motion to suppress evidence of the knife
    and the condition of the house, arguing that the “[l]aw enforcement
    [officers] conducted a warrantless search of [her] residence without
    probable cause and her consent,” and that “all evidence obtain[ed]
    [from the search] should be suppressed.”
    ¶ 14   The trial court conducted a hearing on the motion, at which
    Westbrook and Cooke testified. At the hearing, Westbrook
    described her interactions with N.M., the condition of the house,
    and the photographs she took of the knife. Westbrook did not
    testify that she took any photographs in the house other than those
    of the knife. In addition, Cooke testified about her observations
    when she walked through the house. Cooke said that, at
    Westbrook’s direction, she photographed the interior of the house.
    ¶ 15   Following the hearing, the trial court entered an order finding
    that Westbrook’s and Engdahl’s initial entries into the house were
    lawful because N.M. voluntarily gave them consent to enter. It
    concluded, however, that Bogle’s, Cooke’s, and Miller’s entries (as
    well as these of any other officials) violated Stone’s Fourth
    Amendment rights. Thus, it excluded “all evidence secured through
    5
    such actions . . . includ[ing] all photographs taken during these
    entries.”
    ¶ 16   At trial, Westbrook and Engdahl testified about their
    interactions with N.M. and the condition of the house. The jury
    found Stone guilty on all counts.
    II.   Analysis
    A.   Standard of Review
    ¶ 17   “Review of a trial court’s suppression order presents ‘a mixed
    question of law and fact.’” People v. Peluso, 
    2021 CO 16
    , ¶ 10, ___
    P.3d ___, ___ (quoting People v. Allen, 
    2019 CO 88
    , ¶ 13, 
    450 P.3d 724
    , 728). We review the trial court’s legal conclusions de novo and
    defer to the trial court’s findings of fact that are supported by
    competent evidence in the record. 
    Id.
    ¶ 18   If we conclude that the trial court erred, we next determine
    whether the error is of constitutional dimension. The admission of
    evidence in violation of a defendant’s Fourth Amendment rights is a
    constitutional error. See People v. Summitt, 
    132 P.3d 320
    , 323
    (Colo. 2006). We must reverse if the trial court made a
    constitutional error unless “the evidence properly received against a
    defendant is so overwhelming that the constitutional violation was
    6
    harmless beyond a reasonable doubt.” Bartley v. People, 
    817 P.2d 1029
    , 1034 (Colo. 1991).
    B.   Westbrook’s Entry and Re-Entry into the House
    ¶ 19   Stone first contends that the trial court erred by admitting
    Westbrook’s testimony about the clutter in the house and the
    photographs she took during her initial entry and re-entry into the
    house. Before we address this argument on the merits, however, we
    turn to the parties’ disagreement regarding the specific photographs
    that the court held were inadmissible in its ruling on Stone’s
    suppression motion.
    1.    The Photographs of the House
    ¶ 20   Stone argues that, at trial, the court erred by allowing the
    prosecutor to admit into evidence photographs that the court had
    ruled in its suppression order were inadmissible.
    a.   The Pre-Trial Colloquy
    ¶ 21   On the first day of trial, the prosecutor asked the court to
    clarify its earlier ruling regarding the admissibility of photographs
    taken during the search. Although Westbrook did not say at the
    suppression hearing that she had taken any photographs inside the
    house other than the photographs of the knife, the prosecutor told
    7
    the court on the morning of trial that, during her initial entry and
    re-entry, Westbrook had also used her cell phone to take
    photographs of the interior of the house. The prosecutor said that
    any photographs Westbrook took of the interior of the house were
    similar to the photographs that Cooke took inside the house.
    ¶ 22        Based on the prosecutor’s representation that Westbrook had
    taken photographs depicting the interior of the house, defense
    counsel did not object to the admission of the photographs. But the
    court nonetheless noted that Westbrook had not testified that she
    photographed the interior of the house. The court said to the
    prosecutor, “I heard [Westbrook] just as you heard her on the
    stand. I didn’t get my camera. I took a photograph of the knife.”
    The court said, “Maybe it was [Westbrook] just didn’t explain it.”
    The prosecutor responded, “I think I did not explain that correctly.”
    ¶ 23        At trial, the court admitted photographs of the inside of the
    house, as well as photographs of the knife.
    b.     The Trial Court Erred by Admitting the Photographs of the
    Interior of the House
    ¶ 24        The transcript of the suppression hearing supports the court’s
    original understanding that, while in the house, Westbrook
    8
    photographed the knife but not the interior of the house. At the
    hearing, Westbrook acknowledged that “the only photograph [I] took
    on the first entry was the knife.” She did not mention taking any
    additional photographs after re-entering the house. Rather, at the
    suppression hearing, Cooke was the only witness who said she had
    taken photographs depicting the interior of the house — and the
    court later ruled that Cooke had entered the house unlawfully.
    ¶ 25   The prosecutor’s “clarification” on the first day of trial that
    Westbrook, in fact, photographed the interior of the house was not
    evidence, and thus the trial court erred by treating it as such. See
    Quest Servs. Corp. v. Blood, 
    252 P.3d 1071
    , 1088 n.10 (Colo. 2011).
    This is especially true because the prosecutor’s “clarification”
    contradicted Westbrook’s testimony at the suppression hearing that
    the only photographs she took during her first entry into the house
    depicted the knife.
    ¶ 26   Further, the prosecutor contended that the photographs of the
    interior of the house were “similar” to photographs that Westbrook
    allegedly took — even though, at the suppression hearing,
    Westbrook never said she photographed the interior of the house.
    Moreover, the prosecutor did not establish at trial who took the
    9
    photographs of the interior of the house or, more generally, that
    Westbrook’s alleged photographs of the interior of the house
    actually existed. Thus, based on the evidence presented at the
    hearing, we understand that Cooke took the photographs of the
    interior of the house that were admitted into evidence
    ¶ 27   We hold that the trial court erred by admitting the
    photographs of the interior of the house because the prosecutor did
    not introduce evidence establishing that Westbrook took any such
    photographs; Westbrook testified at the suppression hearing that,
    while in the house, she only photographed the knife; Cooke,
    however, said that she took photographs inside the house; and the
    trial court ruled that Cooke entered the house illegally.
    c.    Even Though the Trial Court Erred by Admitting the
    Photographs of the Interior of the House, the Error Was
    Harmless Beyond a Reasonable Doubt
    ¶ 28   Because we conclude that the trial court erred by admitting
    photographs obtained in violation of Stone’s Fourth Amendment
    rights, we must determine whether the admission of the
    photographs was harmless beyond a reasonable doubt. Bartley,
    817 P.2d at 1034.
    10
    ¶ 29   When determining whether a constitutional error is harmless
    beyond a reasonable doubt, we should consider “(1) the importance
    of the [erroneously admitted] evidence to the [prosecution’s] case;
    (2) whether the evidence is cumulative; and (3) the overall strength
    of the [prosecution’s] case.” People v. Omwanda, 
    2014 COA 128
    , ¶
    32, 
    338 P.3d 1145
    , 1150. The “inquiry is whether the jury’s guilty
    verdict in this ‘trial was surely unattributable to the error.’” 
    Id.
    (quoting Sullivan v. Louisiana, 
    508 U.S. 275
    , 279 (1993)).
    ¶ 30   Here, the error was harmless beyond a reasonable doubt
    because the improperly admitted photographs of the interior of the
    house were cumulative of Westbrook’s testimony regarding her
    observations inside the house, which, as discussed below, infra Part
    II.B.2, was admissible.
    ¶ 31   At trial, Westbrook testified that the photographs depicting the
    interior of the house were consistent with her own observations.
    She testified that the house “was very cluttered[,] . . . dirty[,] . . .
    [and] unsafe.” She noted that the house was unsafe because she
    observed piles of things that could fall on a child; a very young child
    almost falling over a baby gate and tripping over items scattered on
    11
    the floor; and “old dishes and food and . . . everything around [that]
    just was . . . a hazard to a small child.”
    ¶ 32   The photographs of the interior of the house that the court
    admitted into evidence were cumulative because they did not add
    anything material to Westbrook’s description of the cluttered and
    hazardous conditions she saw in the house. See People v. Espinoza,
    
    989 P.2d 178
    , 182 (Colo. App. 1999). Because the photographs
    were cumulative of Westbrook’s testimony, the trial court’s error in
    admitting them could not have contributed to the jury’s verdict and
    was therefore constitutional harmless error. See Griego v. People,
    
    19 P.3d 1
    , 8 (Colo. 2001); Omwanda, ¶ 32, 
    338 P.3d at 1150
    .
    2.   The Photographs of the Knife and Westbrook’s Trial Testimony
    ¶ 33   We next turn to Stone’s argument that the trial court erred by
    admitting the photographs Westbrook took of the knife and her trial
    testimony regarding her observations of the interior of the house.
    Stone contends that the court should have excluded this evidence
    because Westbrook violated Stone’s Fourth Amendment rights when
    she entered the house without Stone’s consent.
    ¶ 34   The trial court concluded that N.M. “knowingly, voluntarily[,]
    and intelligently consented” to Westbrook’s entry, and that N.M.’s
    12
    consent encompassed both Westbrook’s initial entry and her re-
    entry after stepping outside the house to retrieve the camera from
    her car. Stone contends that this conclusion was in error because
    (1) N.M., as a minor at the time, lacked the authority to consent to a
    law enforcement officer’s entry into the house; and (2) even if N.M.
    had the authority to consent to Westbrook’s initial entry, his
    consent did not extend to Westbrook’s re-entry into the house. We
    are not persuaded.
    a.    The Consent Exception to the Warrant Requirement
    i.   Valid Consent
    ¶ 35   A warrantless entry into a person’s home is presumptively
    unreasonable unless it falls within a recognized exception to the
    Fourth Amendment’s warrant requirement. People v. Stock, 
    2017 CO 80
    , ¶ 15, 
    397 P.3d 386
    , 390. The prosecution carries “the
    burden of establishing that [a] warrantless search is . . . justified
    under one of the narrowly defined exceptions to the warrant
    requirement.” People v. Fuerst, 
    2013 CO 28
    , ¶ 11, 
    302 P.3d 253
    ,
    256 (quoting People v. Winpigler, 
    8 P.3d 439
    , 443 (Colo. 1999)).
    ¶ 36   One exception to the warrant requirement is “[a] search
    conducted pursuant to consent freely and voluntarily given by a
    13
    person with ‘common authority’ over the [searched] premises.”
    People v. Strimple, 
    2012 CO 1
    , ¶ 20, 
    267 P.3d 1219
    , 1223. Consent
    is voluntary if it is “the product of an essentially free and
    unconstrained choice by its maker.” People v. Berdahl, 
    2019 CO 29
    , ¶ 20, 
    440 P.3d 437
    , 442 (quoting People v. Munoz-Gutierrez,
    
    2015 CO 9
    , ¶ 16, 
    342 P.3d 439
    , 444). “Conversely, a consensual
    search is involuntary when police overbear the consenting party’s
    will and critically impair the party’s ‘capacity for
    self-determination.’” Munoz-Gutierrez, ¶ 17, 
    342 P.3d at 444
    (quoting Schneckloth v. Bustamonte, 
    412 U.S. 218
    , 225 (1973)).
    ¶ 37   When determining whether a person voluntarily consented to a
    law enforcement officer’s entry into a residence, “courts must apply
    an objective test that takes into account the totality of the
    circumstances and determines whether the defendant could
    reasonably have construed the police conduct to be coercive.”
    Berdahl, ¶ 23, 440 P.3d at 442. A consenting person’s youth is a
    factor in determining the voluntariness of the person’s consent.
    United States v. Gutierrez-Hermosillo, 
    142 F.3d 1225
    , 1231 (10th
    Cir. 1998). However, the fact that the person giving consent is a
    minor does not necessarily preclude effective consent and is only
    14
    one factor within the totality of the circumstances a court must
    consider when determining whether the consent was voluntary.
    Blincoe v. People, 
    178 Colo. 34
    , 37, 
    494 P.2d 1285
    , 1286 (1972); see
    United States v. Sanchez, 
    608 F.3d 685
    , 690 (10th Cir. 2010).
    Other relevant factors include the consenting person’s education,
    intelligence, and state of mind, and whether the person was aware
    that he or she was free to withhold consent. Berdahl, ¶ 23, 440
    P.3d at 442.
    ii.   Consent by a Co-Occupant
    ¶ 38   In certain circumstances, a co-occupant can validly consent to
    a search of the residence even though the law enforcement officers
    are investigating a different co-occupant. Co-occupants “have
    common authority [to consent to a search] where there is ‘mutual
    use of the property by persons generally having joint access [to] or
    control [of the residence] for most purposes.’” Peluso, ¶ 13, ___ P.3d
    at ___ (quoting United States. v. Matlock, 
    415 U.S. 164
    , 171 n.7
    (1974)). If one co-occupant is not present during the search, “the
    consent of one who possesses common authority over [the] premises
    . . . is valid as against the absent, nonconsenting person with whom
    15
    that authority is shared.” Fuerst, ¶ 12, 302 P.3d at 256 (quoting
    Matlock, 
    415 U.S. at 170
    ).
    ¶ 39   Even where the co-occupant lacks actual authority to consent
    to a search, he or she may still possess apparent authority to
    validate the search. Under the apparent authority doctrine, “[a]
    warrantless search is . . . valid based upon the consent of a third
    party whom officers, at the time of the entry, reasonably believe to
    possess common authority over the premises, even if the person in
    fact does not [possess such authority].” Peluso, ¶ 14, ___ P.3d at
    ___. The apparent authority doctrine applies only when the
    consenting party lacked actual authority. Petersen v. People, 
    939 P.2d 824
    , 830-31 (Colo. 1997).
    ¶ 40   When officers seek consent to search a jointly occupied
    residence, “a physically present inhabitant’s express refusal of
    consent to a police search is dispositive as to him, regardless of the
    consent of a fellow occupant.” Georgia v. Randolph, 
    547 U.S. 103
    ,
    122-23 (2006). In order to vitiate a co-occupant’s consent, “(1) the
    objecting occupant must have been physically present on the
    premises as officers ‘propose[d] to make a consent search’; and (2)
    the objecting occupant must have objected as officers ‘propose[d] to
    16
    make a consent search.’” Williams v. People, 
    2019 CO 108
    , ¶ 35,
    
    455 P.3d 347
    , 354 (quoting Fernandez v. California, 
    571 U.S. 292
    ,
    306 (2014)). “[I]f the objecting resident does not take part in the
    threshold colloquy between the officers and his co-occupant, he
    ‘loses out,’” and the co-occupant’s consent will validate the search.
    Id. at ¶ 1, 455 P.3d at 348 (quoting Randolph, 
    547 U.S. at 121
    ).
    b.        The Trial Court Did Not Err by Finding that N.M. Validly
    Consented to Westbrook’s Entry into the House
    ¶ 41    Stone contends that N.M. “had no legal authority over the
    residence to give constitutionally valid third-party consent” because
    he was a minor at the time and Westbrook did not “reasonably
    inquire” regarding his authority. Stone also contends that, after
    being told that Stone was on her way to the house, Westbrook had
    a duty to wait for Stone to arrive and to ask her for permission to
    enter the house. Finally, Stone argues that Westbrook exceeded
    any consent N.M. gave her when she re-entered the house. We
    consider and reject each of these contentions.
    i.      N.M. Voluntarily Consented to Westbrook’s Entry
    ¶ 42    As noted, “the fact that one is a minor does not necessarily
    preclude effective consent . . . .” Blincoe, 178 Colo. at 37, 
    494 P.2d 17
    at 1286. Rather, age is one factor within the totality of the
    circumstances that a court can consider when determining whether
    a person voluntarily consented to a search. Sanchez, 
    608 F.3d at 690
    ; Gutierrez-Hermosillo, 
    142 F.3d at 1231
    . At seventeen, N.M.
    was nearly a legal adult. Stone does not argue that he was
    impaired intellectually or in such a state of mind that he could not
    understand what Westbrook was asking. Moreover, Stone does not
    contend that Westbrook coerced N.M. into letting her into the
    house. N.M. knew Westbrook was a police officer because she
    identified herself as such and wore a uniform. See Sanchez, 
    608 F.3d at 690
    . For these reasons, we conclude that N.M. voluntarily
    gave Westbrook consent to enter the house.
    ii.    N.M. Had Actual Authority to Consent to Westbrook’s Entry
    ¶ 43     We agree with the trial court that N.M. had actual authority to
    consent to Westbrook’s entry. The record shows, and Stone does
    not deny, that N.M. resided in the house and had “joint access [to]
    or control [of it] for most purposes.” Peluso, ¶ 13, ___ P.3d at ___
    (quoting Matlock, 
    415 U.S. at
    171 n.7). Very simply, the house was
    N.M.’s home. Thus, N.M., as a co-occupant, had actual authority to
    consent to Westbrook’s entry into the house. See 
    id.
     (“Where a
    18
    residence is jointly occupied by more than one person, the consent
    of one occupant with common authority over the premises is
    sufficient to permit a warrantless search.”).
    ¶ 44   Because N.M. had actual authority to consent to Westbrook’s
    entry into the house, Stone’s reliance on Illinois v. Rodriguez, 
    497 U.S. 177
     (1990), in support of her contention that Westbrook had a
    duty to reasonably inquire regarding N.M.’s authority, is misplaced.
    Rodriguez addressed an individual’s apparent authority to consent
    to a law enforcement officer’s entry into a residence. Because
    actual authority and apparent authority are mutually exclusive,
    and N.M. had actual authority to consent to Westbrook’s entry for
    the reasons explained above, the apparent authority doctrine does
    not apply here. See Petersen, 939 P.2d at 831.
    ¶ 45   Westbrook also was not required to wait for Stone to arrive
    and to ask her for consent to enter the house. Where a potentially
    objecting co-occupant is “nearby but not invited to take part in the
    threshold colloquy” regarding consent to search the premises, the
    potentially objecting co-occupant “loses out” and the present co-
    occupant’s consent to the search controls. Williams, ¶¶ 24, 35, 455
    P.3d at 352, 354 (quoting Randolph, 
    547 U.S. at 121
    ). Although at
    19
    the time of Westbrook’s initial entry into the house, Westbrook
    knew that Stone would soon be arriving at the house, Stone was not
    present and therefore could not object to the entry. Stone cites to
    no authority suggesting that police officers are required to obtain
    the consent of an absent co-occupant where another co-occupant
    with actual authority has already given valid consent to entry.
    iii.   N.M.’s Initial Consent Extended to Westbrook’s Re-Entry
    ¶ 46      We next address Stone’s contention that Westbrook’s re-entry
    into the house exceeded the scope of N.M.’s consent to her initial
    entry. Stone suggests that Westbrook, “after observing the
    condition [of the house] on the first entry, [was required] to secure a
    search warrant” before she could legally re-enter the house. We
    disagree.
    ¶ 47      Absent an objection to “subsequent, closely related entries and
    searches, after valid consent to an initial entry,” the consenting
    person’s “initial consent [can] extend[] to the subsequent entries.”
    Phillips v. State, 
    625 P.2d 816
    , 818 (Alaska 1980). “[W]hile one
    consensual entry does not entitle a law enforcement official to
    return at any substantially later time, an officer’s momentary
    exit . . . does not invalidate” an otherwise legal search or seizure.
    20
    Commonwealth v. Moye, 
    586 A.2d 406
    , 409 (Pa. Super. Ct. 1990).
    Thus, for consent to encompass a subsequent re-entry, the entry
    and re-entry must be closely related in time and purpose. See
    People v. Franklin, 
    2016 IL App (1st) 140059
    , ¶ 17, 
    62 N.E.3d 1145
    ,
    1150 (The court observed that the officer “never abandoned his
    investigation, relinquished control over the defendant’s house, or
    indicated an intent not to seize [the contraband]. He only briefly
    interrupted his search to call for backup” and to speak to the
    prosecutor. (quoting People v. Logsdon, 
    567 N.E.2d 746
    , 748 (Ill.
    App. Ct. 1991))); cf. United States v. McMullin, 
    576 F.3d 810
    , 816
    (8th Cir. 2009) (holding that consent to an initial entry does not
    extend to a subsequent entry if the purpose of the initial entry has
    been accomplished).
    ¶ 48   Westbrook had not completed her investigation when she
    momentarily stepped out of the house to retrieve her camera. As
    noted above, she wanted the camera so she could take more
    accurate photographs than she could with her cell phone.
    Westbrook’s time out of the house was so brief that she did not
    reach her car before she decided to re-enter. Importantly, there is
    21
    no evidence that N.M. revoked his consent or otherwise objected to
    Westbrook’s re-entry into the house.
    ¶ 49     Based on this record, we conclude that N.M.’s consent to
    Westbrook’s initial entry extended to her re-entry into the house.
    See Phillips, 625 P.2d at 818; Franklin, ¶ 17, 62 N.E.3d at 1150;
    Moye, 
    586 A.2d at 409
    . Because N.M. did not revoke his consent or
    object to Westbrook’s re-entry, Westbrook was not required to ask
    N.M. for consent to re-enter the house. See Phillips, 625 P.2d at
    818.
    ¶ 50     For these reasons, we conclude that the trial court did not err
    by finding that Westbrook’s re-entry was lawful because it fell
    within the scope of the consent N.M. gave her when she first
    knocked on the door.
    C.     Stone’s Challenge to Engdahl’s and Bogle’s Testimony at Trial
    ¶ 51     Stone also appears to challenge the admissibility of Engdahl’s
    trial testimony based on her contention that he entered the house
    illegally. But she does not provide any citations to the record or
    legal authority in support of her argument regarding Engdahl’s
    testimony.
    22
    ¶ 52   For these reasons, Stone’s argument is undeveloped, and we
    do not address it on the merits. See People v. Liggett, 
    2021 COA 51
    ,
    ¶ 53, ___ P.3d ___, ___ (acknowledging that appellate courts do not
    address undeveloped arguments).
    ¶ 53   But even if the argument were developed, because Engdahl’s
    trial testimony regarding the interior conditions of the house was
    cumulative of Westbrook’s testimony, Engdahl’s testimony could
    not have contributed to the jury’s verdict. Thus, any error in the
    admission of Engdahl’s testimony would have been harmless
    beyond a reasonable doubt. See Griego, 19 P.3d at 8; Omwanda,
    ¶ 32, 
    338 P.3d at 1150
    .
    ¶ 54   Finally, Stone also appears to challenge the legality of Bogle’s
    entry into the house. But the trial court excluded Bogle’s testimony
    regarding her observations of the interior of the house. Stone does
    not point to any evidence admitted at trial regarding Bogle’s
    observations of the condition of the house. Therefore, this issue is
    moot.
    III.   Conclusion
    ¶ 55   The judgment of conviction is affirmed.
    JUDGE ROMÁN and JUDGE DAVIDSON concur.
