`
`After a young woman found a pressure cooker bomb hidden under her bed, law
`
`enforcement agents went to the home of the only person she said might want to harm
`
`
`
`
`
`
`
`her: Ethan Guillen.1 The agents entered Ethan’s home, questioned him, and obtained
`
`consent from his father to search the residence. During the search, the agents found
`
`evidence in Ethan’s bedroom indicating his involvement with the pressure cooker
`
`bomb. When one of the agents confronted Ethan with the information and evidence
`
`they had collected, he confessed to making the bomb. The agent immediately
`
`provided the warnings required by Miranda v. Arizona, 384 U.S. 436 (1966), and
`
`Ethan proceeded to make more incriminating statements.
`
`Ethan ultimately entered a conditional plea of guilty to possession of an
`
`unregistered destructive device and an attempt to damage or destroy a building by
`
`means of fire or an explosive. His plea agreement reserved the right to appeal the
`
`district court’s order denying his motion to suppress the physical evidence and
`
`incriminating statements resulting from the search of his home. Exercising that right,
`
`Ethan argues the district court should have suppressed the physical evidence found in
`
`his home because the agents’ warrantless entry and search of his bedroom violated
`
`his Fourth Amendment rights. He also contends the district court should have
`
`suppressed the incriminating statements he made after receiving Miranda warnings
`
`because the agents elicited them through coercion and used an impermissible two-
`
`step interrogation technique to end run around Miranda.
`
`We have jurisdiction under 28 U.S.C. § 1291, and we conclude that the district
`
`court correctly denied Ethan’s suppression motion. No Fourth Amendment violation
`
`
`1 The parties refer to Ethan Guillen; his father, Reynaldo Guillen; and his
`brother, Tyler Guillen, by their first names. In the interest of clarity, we do the same.
`2
`
`
`
`
`
`occurred because Ethan voluntarily consented to the agents’ entry into his home and
`
`because the agents reasonably relied on his father’s consent to search his bedroom.
`
`Ethan’s initial confession, which the district court suppressed, was inadmissible
`
`because the agents failed to provide Miranda warnings before they engaged in
`
`custodial interrogation. But the midstream Miranda warnings Ethan received were
`
`sufficient to advise him of his rights and render his voluntary postwarning statements
`
`admissible. For these reasons, we affirm the district court’s judgment.
`
`I.
`
`On May 31, 2017, law enforcement responded to a 911 call from “MC,” a
`
`young woman who had found an improvised explosive device under her bed. The
`
`device was a pressure cooker sealed with white duct tape and filled with black
`
`powder; homemade napalm; and various types of shrapnel, including nuts, bolts, and
`
`screws. A fuse ran through the pressure cooker’s release valve and connected to an
`
`electric soldering iron, which was plugged into a timer that was plugged into the wall
`
`with a power strip. The device was designed so that the timer would turn on the
`
`soldering iron, which would heat up, ignite the fuse, and cause an explosion.
`
`Fortunately, the bomb never detonated.
`
`Special Agent Zachary Rominger, an agent with the Bureau of Alcohol,
`
`Tobacco, Firearms, and Explosives (ATF), interviewed MC and her mother. When
`
`asked if anyone would want to hurt or kill her, MC could think of only one person—
`
`her ex-boyfriend, Ethan. MC said she had dated Ethan for about six months. After
`
`they broke up, MC explained, Ethan continued to try and communicate with her
`3
`
`
`
`
`
`against her wishes. And at some point, MC’s school provided her with an escort to
`
`class in an effort to stop Ethan’s harassment.
`
`After wrapping things up at MC’s home, law enforcement agents went to
`
`Ethan’s house. At approximately 9:43 p.m., ATF Special Agents Zachary Rominger
`
`and Derek Wright, FBI Special Agent Bomb Technicians Craig Greene and Michael
`
`Anthony, and Albuquerque Police Department Detective James Larranaga knocked
`
`on Ethan’s front door. FBI Supervisor Marco Gonzalez was also present, but he
`
`stayed out by the street when the other five agents approached the house. Detective
`
`Larranaga’s lapel camera captured on video, among other things, the moments
`
`leading up to the agents’ entry into Ethan’s home.
`
`When the agents knocked on the door, Ethan and his brother, Tyler Guillen,
`
`answered. At the time, Ethan was eighteen years old; Tyler was twenty. The agents
`
`asked if they could come inside and talk. Tyler agreed, but Ethan asked if the agents
`
`had a warrant. After Agent Greene said they did not have a warrant, Ethan suggested
`
`they talk in the doorway instead. When the agents asked again if they could come
`
`inside, the brothers had a brief and largely inaudible discussion, during which Tyler
`
`asked Ethan, “Why do you care?” After the discussion, one of the brothers said
`
`“sure.” Agents Rominger and Greene testified that Ethan said “sure,” but Tyler
`
`testified he made that statement. Assessing the conflicting accounts and the lapel
`
`cam video, the district court deemed the agents’ testimony credible and found that
`
`Ethan was the one who said the word “sure.” At this point, Tyler put his hand on
`
`Ethan’s shoulder, and both brothers moved out of the doorway. Agent Greene
`4
`
`
`
`
`
`confirmed: “Are you inviting us in to talk?” One of the brothers responded, “Yeah,
`
`sure.” Then they all went inside the house.
`
`Following a protective sweep of the residence, during which no evidence was
`
`gathered, Agents Rominger and Greene interviewed Ethan at the kitchen table while
`
`other agents spoke with Tyler in the hallway. Tyler told the agents that their father,
`
`Reynaldo, is a musician and was practicing with his band in Santa Fe that night.
`
`Reynaldo returned home about 18 minutes after the agents’ entry. He informed the
`
`agents he had recently bought a pressure cooker for Ethan and, at the agents’ request,
`
`looked for it. After Reynaldo could not find the pressure cooker, he asked Ethan
`
`where it was. Ethan said he had taken it to his mother’s house. Reynaldo then called
`
`Ethan’s mother to see if she had the pressure cooker. Ethan’s mother said she did not
`
`know whether the pressure cooker was at her house and told Reynaldo she would
`
`have to look for it.
`
`While questioning continued, Reynaldo confirmed he owned the house and
`
`verbally consented to a search. He also signed a search consent form. At that point,
`
`the agents called in the Albuquerque Bomb Squad to assist. Shortly after the search
`
`began, the agents asked Reynaldo if he owned a soldering iron. Reynaldo said he
`
`did, but he couldn’t find it. The agents’ search did not uncover the soldering iron
`
`either, but they discovered a table on the back porch with burn marks and a piece of
`
`fuse burnt onto it. The bomb squad also found white duct tape matching the tape on
`
`the pressure cooker bomb, black duct tape, latex gloves, scissors, super glue, and zip
`
`
`
`5
`
`
`
`ties in a backpack on the floor of the master bedroom. The master bedroom was
`
`Ethan’s room.
`
`Agents Rominger and Greene questioned Ethan at the kitchen table for about
`
`50 minutes, during which time he repeatedly denied any involvement with making
`
`the pressure cooker bomb. After the search ended, the agents asked Ethan, who was
`
`then sitting on the couch in the living room, to return to the kitchen table. Agent
`
`Rominger then laid out the evidence discovered during the search, told Ethan it
`
`pointed to him, and asked if he created the improvised explosive device. Ethan
`
`hesitated, took a deep breath, and then said: “Yes, I made it.” Agent Rominger
`
`immediately read Ethan his Miranda rights.
`
`Ethan acknowledged he understood his rights, continued to respond to the
`
`agents’ questions, and provided information about his involvement with making the
`
`device for the next 20 to 40 minutes. Among other things, Ethan described how he
`
`made the pressure cooker bomb, explained how he planted it under MC’s bed, and
`
`told the agents he wanted MC dead. He also took the agents into his room and
`
`showed them the items he used to build the device, including the white duct tape,
`
`gloves, and super glue stored in his backpack. Ethan never requested a lawyer or
`
`asked the agents to stop questioning him. And he answered all of their questions
`
`except one—whether he planned to make another device to kill MC.
`
`Ethan was charged with possession of an unregistered destructive device, in
`
`violation of 26 U.S.C. § 5861(d), and an attempt to destroy a building by fire or
`
`explosive, in violation of 18 U.S.C. § 844(i). In district court, Ethan filed a motion
`6
`
`
`
`
`
`to suppress his self-incriminating statements and the physical evidence obtained from
`
`the search of his home. Ethan argued that the agents violated his Fourth Amendment
`
`rights by entering his house and searching his bedroom without a warrant and without
`
`his consent. He also contended that the agents violated his Fifth Amendment rights
`
`by questioning him without first providing Miranda warnings.
`
`The district court suppressed Ethan’s pre-Miranda confession but denied his
`
`motion as to the remaining statements and evidence. Starting with the Fourth
`
`Amendment claims, the district court found that both Ethan and his brother
`
`voluntarily consented to the agents’ entry into their home. The district court also
`
`determined the search of Ethan’s bedroom was lawful because his father had apparent
`
`authority to consent to it.
`
`Turning to the Fifth Amendment claims, the district court found the agents’
`
`questioning moved beyond simply attempting to elicit information to custodial
`
`interrogation when they confronted Ethan with the evidence discovered during the
`
`search. Because Agent Rominger had not yet warned Ethan of his Miranda rights,
`
`the district court suppressed the initial confession Ethan made in response to this
`
`custodial interrogation. But the district court concluded that Agent Rominger’s
`
`administration of the Miranda warnings after that initial statement was sufficient to
`
`advise Ethan of his rights and render his postwarning statements admissible.2
`
`
`2 Following the denial of his suppression motion, Ethan twice requested the
`district court to reconsider its factual finding that he consented to the agents’ entry into
`his home. In support, Ethan provided an audio enhancement of the previously
`submitted video taken on Detective Larranaga’s lapel camera and a forensic report
`7
`
`
`
`
`
`Ethan subsequently pleaded guilty, but he reserved the right to appeal the
`
`district court’s denial of his motion to suppress. This is his appeal.
`
`II.
`
`When reviewing the denial of a suppression motion, we view the evidence in
`
`the light most favorable to the government, accept the district court’s factual findings
`
`unless they are clearly erroneous, and review legal conclusions de novo. United
`
`States v. Cortez, 965 F.3d 827, 833 (10th Cir. 2020). Ethan argues the district court
`
`erred by not suppressing the physical evidence found in his home and his post-
`
`Miranda statements in the face of Fourth and Fifth Amendment violations.
`
`A.
`
`The Fourth Amendment guarantees the right of people to be “secure in their
`
`persons, houses, papers, and effects against unreasonable searches and seizures.”
`
`U.S. Const. amend. IV. Ethan contends the agents’ warrantless entry into his home
`
`violated that right for two reasons. First, he denies he gave consent to law
`
`enforcement to enter the residence. Second, he argues that even if he did consent to
`
`the entry, his consent was not voluntary. Ethan also claims the search of his bedroom
`
`and its contents was unlawful under the Fourth Amendment because his father lacked
`
`apparent authority to consent to the search. We address Ethan’s arguments in turn.
`
`
`
`
`outlining the methods and procedures used to create the enhanced material. The district
`court denied both of Ethan’s motions to reconsider. Because Ethan has not specifically
`challenged the district court’s reasons for doing so, we need not address them here.
`8
`
`
`
`
`
`1.
`
`We first consider whether the district court erred when it found Ethan
`
`voluntarily consented to the agents’ entry into his home. Voluntary consent is a
`
`longstanding exception to the general requirement that law enforcement officers must
`
`have a warrant to enter a person’s home. United States v. Warwick, 928 F.3d 939,
`
`943 (10th Cir. 2019). The exception applies when the government proves (1) the
`
`officers received either express or implied consent and (2) that consent was freely
`
`and voluntarily given. United States v. Jones, 701 F.3d 1300, 1317 (10th Cir. 2012).
`
`Whether officers obtained valid consent to enter a home is a question of fact
`
`determined through the totality of the circumstances. Id. at 318. Accordingly, we
`
`review the district court’s finding of consent under the clearly-erroneous standard.
`
`United States v. Guerrero, 472 F.3d 784, 789 (10th Cir. 2007).
`
`Ethan first argues that he never actually consented to the agents’ entry into his
`
`home. In doing so, however, he fails to meaningfully grapple with the district court’s
`
`factual findings. Ethan did initially object to law enforcement entering his home, but
`
`the district court found he subsequently consented to the agents’ entry by saying
`
`“sure” in response to their second request to come inside. In addition to its repeated
`
`viewings of the lapel cam video, the district court based its finding on credible agent
`
`testimony that Ethan was the one who said “sure.”
`
`“This court is loath to second-guess a district court’s determination of a
`
`witness’s credibility.” United States v. Asch, 207 F.3d 1238, 1243 (10th Cir. 2000).
`
`We have no basis for doing so here. Neither Ethan’s nor Tyler’s mouth is visible on
`9
`
`
`
`
`
`the lapel cam video when the word “sure” is spoken. And Ethan has not shown the
`
`district court’s credibility determination is internally inconsistent. Warwick, 928
`
`F.3d at 944. He points out that the district court also found Tyler’s testimony
`
`credible, but that credibility determination concerned Ethan’s privacy preferences,
`
`not who said “sure” during the initial encounter at the door. Thus, despite Tyler’s
`
`contrary testimony, the district court did not clearly err when it found Ethan orally
`
`consented to the agents’ entry.
`
`The district court likewise did not clearly err when it determined Ethan
`
`impliedly consented to the entry by stepping away from the doorway and allowing
`
`the agents to enter the house. See Guerrero, 472 F.3d at 789–90 (“[C]onsent must be
`
`clear, but it need not be verbal. Consent may instead be granted through gestures or
`
`other indications of acquiescence, so long as they are sufficiently comprehensible to
`
`a reasonable officer.”). Again relying on his brother’s testimony, Ethan argues his
`
`movement away from the door was caused by Tyler shoving him out of the way. But
`
`Agent Rominger testified that Tyler did not physically remove Ethan from the
`
`doorway. Specifically, Agent Rominger explained that Tyler put his hand on Ethan’s
`
`shoulder, and then Ethan walked out of the way on his own accord. Consistent with
`
`the agent’s credible testimony, the district court determined there was no visible push
`
`on the lapel cam video and found that both brothers cleared the way for the agents to
`
`enter. The district court’s determination that Ethan consented through his actions is,
`
`at a minimum, not clear error.
`
`
`
`10
`
`
`
`Ethan next argues that even if he consented to the agents’ entry, his consent
`
`was not voluntary. Consent is voluntary if it is unequivocal and specific, freely and
`
`intelligently given, and not the product of duress or coercion. Warwick, 928 F.3d at
`
`945. When examining the totality of the circumstances to determine the
`
`voluntariness of consent, some relevant considerations include
`
`physical mistreatment, use of violence, threats, promises, inducements,
`deception, trickery, or an aggressive tone, the physical and mental
`condition and capacity of the defendant, the number of officers on the
`scene, and the display of police weapons. Whether an officer reads a
`defendant his Miranda rights, obtains consent pursuant to a claim of
`lawful authority, or informs a defendant of his or her right to refuse
`consent also are factors to consider in determining whether consent given
`was voluntary under the totality of the circumstances.
`
`Id. (quoting Jones, 701 F.3d at 1318).
`
`According to Ethan, any consent he gave was involuntary because he had no
`
`choice but to submit to the agents’ show of authority. More specifically, Ethan says
`
`his consent was necessarily coerced for several reasons, including (1) the presence of
`
`multiple officers, two of whom were in uniform and visibly armed; (2) the agents’
`
`repeated requests to enter; and (3) his characteristics as a youth lacking prior
`
`experience with law enforcement. We are not persuaded.
`
`The presence of multiple officers at the time Ethan consented increased the
`
`coercive nature of the encounter, but that factor is not dispositive. United States v.
`
`Iribe, 11 F.3d 1553, 1557 (10th Cir. 1993) (holding that the district court clearly
`
`erred when it found consent involuntary based on the presence of five officers
`
`because numerous factors indicated the resident voluntarily consented, including that
`
`
`
`11
`
`
`
`she was not coerced, frightened or otherwise threatened; she had a cordial
`
`conversation with officers spoken in low volume; and the officers made no promises
`
`or threats in an attempt to extract her consent). Most of the agents were dressed in
`
`plain clothes, and their weapons were concealed. And the two uniformed officers
`
`never drew their weapons or otherwise brandished them. Thus, aside from the mere
`
`number of officers present, no other evidence in the record suggests Ethan faced a
`
`display of force designed to overbear.
`
`Ethan points to no credible evidence of coercive tactics such as physical
`
`mistreatment, use of violence, threats, promises, inducements, deception, or trickery.
`
`The agents spoke in a casual, rather than an aggressive, manner. And they never
`
`demanded entry or otherwise claimed any lawful authority to be admitted. Under
`
`these circumstances, neither the agents’ multiple requests to enter the Guillen
`
`residence nor Ethan’s initial objection rendered his subsequent consent involuntary.
`
`See United States v. Cruz-Mendez, 467 F.3d 1260, 1263, 1266–68 (10th Cir. 2006)
`
`(upholding district court’s finding of voluntary consent when the resident repeatedly
`
`refused the officers’ initial requests and told them they needed a warrant to search a
`
`home but subsequently consented to the search).
`
`The record evidence also shows that Ethan’s consent was intelligently given.
`
`It is true that the agents did not inform Ethan he could refuse their request to enter
`
`the house and that Ethan lacked prior experience with law enforcement. But Ethan
`
`was a legal adult who knew enough about his rights to ask the agents if they had a
`
`warrant to enter his home. See United States v. Carloss, 818 F.3d 988, 998–99 (10th
`12
`
`
`
`
`
`Cir. 2016) (explaining that an advisement of the right to refuse a warrantless entry is
`
`not a prerequisite for voluntary consent and that a prior refusal of consent showed
`
`awareness of the right to do so). He also was intelligent enough to build an
`
`improvised explosive device that an experienced bomb technician described as one of
`
`the most sophisticated devices he had ever seen in New Mexico. For these reasons,
`
`the district court’s finding that Ethan voluntarily consented to the agents’ entry into
`
`his home is not clearly erroneous.
`
`2.
`
`Ethan also challenges the search of his bedroom, backpack, and nightstand on
`
`the ground that his father, Reynaldo, did not have authority to consent to the search.
`
`Whether the agents reasonably relied on Reynaldo’s consent to search Ethan’s
`
`bedroom and its contents is a legal question we review de novo. United States v.
`
`Kimoana, 383 F.3d 1215, 1222 (10th Cir. 2004).
`
`An officer may obtain valid consent to search from a third party with either
`
`actual or apparent authority over the subject property. United States v. Romero, 749
`
`F.3d 900, 905 (10th Cir. 2014). Actual authority exists when a third party “has either
`
`(1) mutual use of the property by virtue of joint access, or (2) control for most
`
`purposes.” United States v. Rith, 164 F.3d 1323, 1329 (10th Cir. 1999). When actual
`
`authority is lacking, “a third party has apparent authority to consent to a search when
`
`an officer reasonably, even if erroneously, believes the third party possesses authority
`
`to consent.” United States v. Andrus, 483 F.3d 711, 716 (10th Cir.), decision
`
`clarified on denial of reh’g, 499 F.3d 1162 (10th Cir. 2007). The test for apparent
`13
`
`
`
`
`
`authority is objective: Would “the facts available to the officer at the moment warrant
`
`a [person] of reasonable caution [to believe] that the consenting party had authority
`
`over the premises?” Romero, 749 F.3d at 905 (quoting Illinois v. Rodriguez, 497
`
`U.S. 177, 188 (1990)).
`
`Critical here is the parent-child relationship between Ethan and his father.
`
`When a child—even an adult child—lives in a parent’s home, the parent is presumed
`
`to have “control for most purposes over the property and therefore actual authority to
`
`consent to a search of the entire home.” Id.; see also Rith, 164 F.3d at 1331
`
`(applying presumption and holding that the defendant’s parents had actual authority
`
`to consent to a search of their 18-year-old son’s bedroom). The presumption holds
`
`true unless “rebutted by facts showing an agreement or understanding between the
`
`[child] and the [parent] that the latter must have permission to enter the [child’s]
`
`room.” Rith, 164 F.3d at 1330–31. Relevant facts include a lock on the child’s
`
`bedroom door, an explicit or implicit agreement that the parent will not enter the
`
`room without the child’s consent, and payment of rent by the child. Id.
`
`At the suppression hearing, Reynaldo testified that he had agreed to only enter
`
`Ethan’s bedroom with Ethan’s permission. Tyler also testified about this
`
`arrangement and described how Ethan guarded his privacy by habitually locking his
`
`bedroom door to keep everyone out when he was inside. The government does not
`
`argue those facts are insufficient to rebut the presumption of actual authority.
`
`Instead, it contends that Reynaldo had apparent authority because the agents who
`
`
`
`14
`
`
`
`searched the house were unaware of those facts and thus reasonably relied on the
`
`presumption of control established by Ethan’s relationship with his father. We agree.
`
`At the time of the search, the agents knew Reynaldo owned the house and
`
`permitted Ethan to live there. See Romero, 749 F.3d at 906 (“An owner of a house is
`
`presumed to have control for most purposes of the entire house, including the
`
`bedroom of a [ ]child permitted to live there.”). Although the door to Ethan’s
`
`bedroom had a lock on it, which to some extent undermines Reynaldo’s apparent
`
`authority, the door was wide open when the agents arrived. Ethan never objected to
`
`the search. Neither did Reynaldo or Tyler. And at no point did any of the Guillens
`
`limit where the agents could look.
`
`Even if, as Ethan maintains, the agents knew he occupied the master bedroom
`
`when the search began, they had no way of knowing Reynaldo only entered that room
`
`with Ethan’s permission. When Reynaldo voluntarily consented to the search of the
`
`home, he did not mention the agreement he had with Ethan about access to the master
`
`bedroom. Ethan and Tyler likewise said nothing about any privacy arrangement
`
`amongst the household members. Tyler’s statement that Ethan is “usually in his
`
`room doing his own thing” may shed light on Ethan’s personality, but it raises no
`
`doubt about Reynaldo’s control over his son’s bedroom. Because the agents
`
`reasonably believed Reynaldo had authority to consent, they were not required to
`
`make further inquiries “merely because one can imagine some way that additional
`
`facts might alter their analysis.” Id. at 907.
`
`
`
`15
`
`
`
`Under the totality of the circumstances, the facts known to the agents at the
`
`time of the search created an objectively reasonable perception that Reynaldo had
`
`authority to consent to the search of Ethan’s bedroom. If the agents had learned that
`
`Ethan habitually locked his bedroom door to keep everyone out when he was inside
`
`and that his father did not enter the bedroom without permission, they may no longer
`
`have been justified in relying on Reynaldo’s consent. But the district court found
`
`they did not know those facts when they searched Ethan’s bedroom. This after-
`
`acquired factual knowledge, therefore, has no bearing on the reasonableness of the
`
`agents’ belief in Reynaldo’s authority at the time of the search. Id. at 907–08.
`
`Ethan also contends that even if Reynaldo had apparent authority over the
`
`master bedroom, the agents could not reasonably believe he had authority to consent
`
`to a search of the backpack and nightstand in that room. We reject that argument as
`
`well.
`
`“Common authority over a residence does not necessarily imply common
`
`authority over all locations or objects within the residence.” United States v. Bass,
`
`661 F.3d 1299, 1305 (10th Cir. 2011). But when general authority to consent exists,
`
`“we should not look for ‘metaphysical subtleties’ to define the boundaries of that
`
`authority.” Id. at 1306 (quoting Frazier v. Cupp, 394 U.S. 731, 740 (1969)). Thus, a
`
`“protected expectation of privacy may exist where the defendant has taken some
`
`special steps to protect his personal effects from the scrutiny of others, but does not
`
`unquestionably exist where the co-occupant has ready access (perhaps not theretofore
`
`
`
`16
`
`
`
`exercised) to the place searched.” Id. (quoting 4 Wayne R. LaFave, Search and
`
`Seizure § 8.3(f), at 168–69 (4th ed. 2004)).
`
`Ethan took no “special steps” to protect the backpack or nightstand in his room
`
`from scrutiny. The door to Ethan’s bedroom was wide open when the agents arrived,
`
`and neither the backpack nor the nightstand was locked or otherwise secured. In fact,
`
`the backpack was found lying on the floor of the master bedroom, “hardly an object
`
`shouting ‘Do Not Enter.’” See id. What’s more, Reynaldo—whom the agents knew
`
`was a musician—stored musical equipment and clothes in the master bedroom, which
`
`would make it appear that he had ready access to the room and its contents. In light
`
`of those facts and the apparent authority Reynaldo generally had over Ethan’s
`
`bedroom, the agents reasonably believed Reynaldo’s authority to consent extended to
`
`the search of the backpack and nightstand in that room.
`
`United States v. Salinas–Cano, 959 F.2d 861 (10th Cir. 1992), which Ethan
`
`cites to support his argument, does not persuade us otherwise. In Salinas–Cano, this
`
`court held that a resident of an apartment lacked the authority to consent to the search
`
`of a suitcase her boyfriend (i.e., the defendant) had left there. Id. at 865–66. Prior to
`
`the search, the girlfriend told the police she was not the co-owner of the suitcase and
`
`that it belonged exclusively to the defendant. Id. at 865. Because the couple spent
`
`five nights a week in separate residences, which suggests at least one of them desired
`
`his or her own space and the resulting privacy, we analyzed the case as one in which
`
`a host consents to the search of an object owned by a guest. See id. at 863; see also
`
`Bass, 661 F.3d at 1306. The guest-host relationship is far different from that of a
`17
`
`
`
`
`
`child living in his parent’s home, where the parent is presumed to have control for
`
`most purposes of the child’s bedroom. See Romero, 749 F.3d at 906.
`
`The more instructive precedent here is United States v. Andrus, in which we
`
`held that a father had apparent authority to consent to the search of a computer
`
`located in his adult son’s bedroom. 483 F.3d at 720–22. In Andrus, we likened a
`
`computer to a suitcase, footlocker, and other containers that command a high degree
`
`of privacy. Id. at 718. But we concluded the facts known to the officers when the
`
`search began created an objectively reasonable perception that the father had
`
`authority over the computer. Id. at 722. Those facts included: (1) the defendant’s
`
`father owned the house and lived there with other family members; (2) the father paid
`
`the internet bill; (3) the computer was in the defendant’s bedroom, but the father had
`
`access to the room; (4) the computer was in plain view on a desk and appeared
`
`available for use by other household members; and (5) the father did not do or say
`
`anything to indicate he lacked control over the computer. Id. at 720–21.
`
`The defendant in Andrus argued that the search was unreasonable because his
`
`computer was “locked” to third parties due to its password protection, a fact he said
`
`the officers would have known had they asked questions of his father prior to the
`
`search. Id. at 721. We rejected this argument and declined to place the onus on the
`
`officers to affirmatively ask the defendant’s father if the computer was password
`
`protected before they relied on his consent. Id. Without an affirmative statement by
`
`the father suggesting he did not have authority to access the defendant’s computer,
`
`the officers reasonably believed such authority in fact existed. Id. at 721–22.
`18
`
`
`
`
`
`As in Andrus, the surrounding circumstances known to the agents here would
`
`not cause a reasonable person to doubt Reynaldo’s consent and refrain from acting on
`
`it without further inquiry. Because the agents were reasonable in believing Reynaldo
`
`had the requisite authority to consent to a search of Ethan’s bedroom and its contents,
`
`no Fourth Amendment violation occurred.3
`
`B.
`
`Ethan also alleges violations of his Fifth Amendment rights due to law
`
`enforcement questioning him without providing Miranda warnings. Because the
`
`initial confession Ethan gave before Agent Rominger advised him of his Miranda
`
`rights was suppressed, Ethan’s argument focuses on his post-Miranda statements,
`
`which the district court deemed admissible. Ethan claims the Miranda warnings he
`
`received after his initial confession were insufficient to effectively advise him of his
`
`rights and render his postwarning statements admissible. In addition, Ethan says all
`
`of his incriminating statements, along with the waiver of his Miranda rights, were
`
`involuntary and obtained in violation of the Fifth Amendment.
`
`1.
`
`The Self–Incrimination Clause of the Fifth Amendment guarantees that “[n]o
`
`person . . . shall be compelled in any criminal case to be a witness against himself.”
`
`U.S. Const. amend. V. In Miranda v. Arizona, the Supreme Court concluded that
`
`
`3 We need not address the government’s alternative argument that the evidence
`in Ethan’s bedroom inevitably would have been discovered because the agents would
`have obtained a search warrant absent consent.
`19
`
`
`
`
`
`“the process of in-custody interrogation of persons suspected or accused of crime
`
`contains inherently compelling pressures which work . . . to compel him to speak
`
`where he would not otherwise do so
