    Defendant-Appellant.
    ORDER AND JUDGMENT *
    Before BRISCOE, Chief Judge, EBEL and HOLMES, Circuit Judges.
    While each member of this panel provides different reasoning to reach the
    result, we affirm Mr. Sanchez-Gallegos’s conviction. Both Judge Holmes and
    Chief Judge Briscoe conclude that the district court did not err in admitting Mr.
    Sanchez-Gallegos’s initial un-Mirandized incriminating statement, reasoning that
    Miranda did not apply because Mr. Sanchez-Gallegos was not in custody when he
    made this statement. While Judge Holmes reasons that Mr. Sanchez-Gallegos was
    not in custody based on the totality of the circumstances considered in the context
    *
    This Order and Judgment is not binding precedent, except under the
    doctrines of law of the case, res judicata, and collateral estoppel. It may be cited,
    however, for its persuasive value consistent with Federal Rule of Appellate
    Procedure 32.1 and Tenth Circuit Rule 32.1.
    of a routine fixed border checkpoint as established in United States v. Massie, 
    65 F.3d 843
     (10th Cir. 1995), Chief Judge Briscoe concludes that the encounter with
    law enforcement exceeded the parameters of Massie. Nonetheless, Chief Judge
    Briscoe reasons that Mr. Sanchez-Gallegos was not in custody based on the
    totality of the circumstances. Judge Ebel concludes that the district court erred in
    admitting Mr. Sanchez-Gallegos’s initial incriminating statement, reasoning that
    Mr. Sanchez-Gallegos was in custody when this statement was made based on the
    totality of the circumstances. However, Judge Ebel reasons that this error was
    harmless because Mr. Sanchez-Gallegos’s extensive and detailed post-Miranda
    statements were admissible and vastly outweighed the impact of the initial un-
    Mirandized incriminating statement. Accordingly, for the foregoing reasons, we
    AFFIRM Mr. Sanchez-Gallegos’s conviction.
    ENTERED FOR THE COURT
    PER CURIAM
    -2-
    09-2146, United States v. Sanchez-Gallegos
    HOLMES, J., concurring.
    The defendant-appellant, Adan Sanchez-Gallegos, was indicted on one count
    of conspiracy to transport illegal aliens in violation of 
    8 U.S.C. § 1324
    (a)(1)(A)(ii).
    Prior to trial, Mr. Sanchez-Gallegos filed two motions to suppress—one seeking to
    suppress physical evidence found in his vehicle and on his person, and the other
    seeking to suppress the statements he made to law enforcement officers. The district
    court denied both motions, and a jury found Mr. Sanchez-Gallegos guilty of the
    charged conspiracy offense. Mr. Sanchez-Gallegos appeals his conviction, arguing,
    inter alia, that the district court erred in denying his motion to suppress his initial
    allegedly incriminatory statement to law enforcement. Exercising our jurisdiction
    pursuant to 
    28 U.S.C. § 1291
    , we AFFIRM his conviction.
    BACKGROUND 1
    Around 1:00 p.m. on December 10, 2005, a Chevrolet Suburban vehicle
    bearing a California license plate pulled into a fixed Border Patrol checkpoint on
    I-25 near Radium Springs, New Mexico. Border Patrol Agent Gonzalez was
    conducting primary inspections, and he approached the vehicle and introduced
    himself. He asked in English about the driver’s citizenship, to which the driver
    (later determined to be Mr. Sanchez-Gallegos) responded that he was a U.S.
    1
    We construe all facts in the light most favorable to the government as
    the prevailing party. United States v. Salazar, 
    609 F.3d 1059
    , 1063 (10th Cir.
    2010).
    citizen. In conducting the primary inspection, Agent Gonzalez walked around the
    vehicle and noted the California license plate. Agent Gonzalez testified that, in
    his experience, it was unusual to see California license plates at an I-25
    checkpoint because they were more likely to be seen along the east-west corridor
    of I-10. Agent Gonzalez returned to the driver and inquired about his travel
    plans. The driver had difficulty responding, so Agent Gonzalez switched to
    Spanish. 2 Agent Gonzalez repeated his initial inquiry about the driver’s
    citizenship, and this time the driver responded that he was a legal permanent
    resident from Mexico. Agent Gonzalez asked to see his immigration papers, and
    the driver provided a copy—rather than the original—of his Permanent Resident
    card, which identified him as Adan Sanchez-Gallegos. In response to questions
    about ownership of the vehicle and his travel plans, Mr. Sanchez-Gallegos
    explained that he had rented the Suburban, and that he was headed from Anthony,
    New Mexico, to Albuquerque, en route to Chicago. Agent Gonzalez testified that
    Mr. Sanchez-Gallegos appeared nervous during this encounter as he was avoiding
    eye contact, gripping the steering wheel, and talking in a nervous tone.
    Agent Gonzalez asked for permission to inspect the vehicle further, and Mr.
    Sanchez-Gallegos gave his consent. Agent Gonzalez then had Mr.
    Sanchez-Gallegos move the Suburban to the secondary inspection area and
    2
    The rest of Mr. Sanchez-Gallegos’s encounter with the Border Patrol
    agents was conducted in Spanish.
    -2-
    confirmed that he had Mr. Sanchez-Gallegos’s consent to inspect the vehicle. At
    this point, another Border Patrol agent—a trained canine handler—approached the
    vehicle. Mr. Sanchez-Gallegos was asked to stand aside while the canine search
    was performed. Shortly thereafter, Agent Gonzalez was informed that the canine
    had alerted to Mr. Sanchez-Gallegos’s vehicle.
    Based on this alert, Agent Gonzalez asked Mr. Sanchez-Gallegos to come
    into the checkpoint office so that the vehicle could be inspected further. Before
    allowing him to enter the office, Agent Gonzalez asked Mr. Sanchez-Gallegos for
    permission to conduct a pat-down search of him as a safety precaution, and Mr.
    Sanchez-Gallegos consented to the search. While conducting this search, Agent
    Gonzalez felt a large bulge, which Mr. Sanchez-Gallegos explained was his
    money for purchasing a trailer or mobile home. Mr. Sanchez-Gallegos showed
    Agent Gonzalez the money ($7915 in United States currency plus 1800 Mexican
    Pesos).
    Agent Gonzalez then “went back” to his “primary duties to conduct more
    immigration inspections while the [Border Patrol] agents inspected the vehicle.”
    R., Vol. III, at 23 (Suppression Hr’g Tr., dated Dec. 21, 2007). Agent Gonzalez
    subsequently asked for and received additional identification from Mr.
    Sanchez-Gallegos and busied himself “run[ning] checks” of Mr. Sanchez-
    Gallegos’s immigration and criminal histories. Id. at 25. The Border Patrol
    agents searching the interior of the Suburban discovered a duffle bag containing
    -3-
    five Mexican birth certificates and a “Certificate of Good Conduct,” which is a
    document issued by the Mexican government.
    Agent Gonzalez testified that upon discovering these documents, the agents
    were concerned that these documents belonged to six children who were being
    smuggled through the desert into the United States. Agent Gonzalez, with another
    Border Patrol agent observing, asked Mr. Sanchez-Gallegos about the source and
    purpose of the documents and the cash. Mr. Sanchez-Gallegos claimed that he
    was unaware of the documents and provided no further explanation for the cash.
    Once the search of the vehicle was completed, Agent Gonzalez returned to
    Mr. Sanchez-Gallegos and expressed his suspicion that Mr. Sanchez-Gallegos was
    involved in smuggling children through the desert. In response, Mr. Sanchez-
    Gallegos informed Agent Gonzalez that “he had that money as part of a payment
    to take some children to . . . Chicago.” Id. at 29. At the time that he gave this
    statement, Mr. Sanchez-Gallegos had been at the checkpoint for approximately
    forty to fifty minutes.
    Following this admission, Agent Gonzalez and the other Border Patrol
    agent read Mr. Sanchez-Gallegos a Miranda warning in Spanish and presented an
    Advice of Rights form to him that was written in Spanish. Agent Gonzalez read
    the form aloud, and Mr. Sanchez-Gallegos signed the form. Mr.
    Sanchez-Gallegos then informed Agent Gonzalez that the children were not in the
    desert, but rather were in Albuquerque with “Victor.” Mr. Sanchez-Gallegos was
    -4-
    to pick them up from “Victor” and transport them to their family in Chicago.
    Agent Gonzalez then called the duty agent with Immigration and Customs
    Enforcement (“ICE”), Agent Carroll, who was unable to come immediately to the
    checkpoint. However, Agent Carroll promised to arrange for an ICE agent from
    Albuquerque to call Agent Gonzalez.
    At approximately 2:20 p.m., Agent Gonzalez received a call from
    Albuquerque ICE Agent Franco. Agent Franco asked Agent Gonzalez to see if
    Mr. Sanchez-Gonzalez would contact “Victor” in an effort to locate the children.
    He agreed to do so, and during this call, “Victor” explained that the children
    “were going to be at the Motel 6 near [the] Cesar Chavez exit on I-25.” Id. at 36.
    Based on this information, Agent Gonzalez called the motel and asked if a man
    had checked in with six children, but at that time, no one matching that
    description had checked in.
    At approximately 4:30 p.m., Agent Carroll arrived at the checkpoint. He
    briefly discussed the situation with Agent Gonzalez, and then interviewed Mr.
    Sanchez-Gallegos after again obtaining a waiver of his Miranda rights. Mr.
    Sanchez-Gallegos explained that he had flown from Chicago to Albuquerque
    several days prior, rented the Suburban, and spent several days looking for a
    trailer or mobile home to purchase. After a day or two, he drove south to
    Anthony, New Mexico, where he met his friend, “Victor.” He took a day trip to
    Juarez, Mexico, and, while there, he received a phone call from “Victor” asking if
    -5-
    he would smuggle some children, who were illegally present in the United States,
    from Albuquerque to Chicago, and he agreed to do so. Upon returning to
    Anthony, Mr. Sanchez-Gonzalez received the children’s documentation from
    “Victor,” then left Anthony on December 10, 2005, to pick up the children in
    Albuquerque.
    Meanwhile, Agent Franco set up surveillance in Albuquerque on the Motel
    6. At approximately 5:00 p.m., she received information that “Victor” had
    checked in with six children and three other adults. The agents knocked on the
    doors of his rooms. In one room, the agents found an adult male, later identified
    as Victor Manuel Cardoza-Avitia, Mr. Sanchez-Gallegos’s co-defendant; an adult
    female, later identified as Victor’s wife; and six children—the same children
    whose documentation had been seized from Mr. Sanchez-Gallegos’s luggage.
    Agent Franco then called Agent Carroll to tell him the children had been located.
    Subsequently, Mr. Sanchez-Gallegos was indicted for conspiracy to transport
    illegal aliens.
    Mr. Sanchez-Gallegos filed two motions to suppress—one seeking to
    suppress the documents found in the Suburban and the cash found on his person,
    and the other seeking to suppress the statements he made to Agents Gonzalez and
    Carroll. Following a hearing, the district court denied both motions, finding that
    the agents had reasonable suspicion to direct Mr. Sanchez-Gallegos to the
    secondary inspection area, and probable cause to search the interior of his vehicle
    -6-
    following the dog alert and the discovery of the cash on his person. The district
    court noted that Mr. Sanchez-Gallegos consented to the canine search. The
    district court found that Mr. Sanchez-Gallegos was not in custody when he made
    his initial incriminating statement, and his subsequent statements to Agents
    Gonzalez and Carroll were voluntarily and freely made after waiving his Miranda
    rights.
    Following the district court’s denial of his motions to suppress, Mr.
    Sanchez-Gallegos proceeded to trial and was convicted of one count of conspiracy
    to transport illegal aliens. This timely appeal followed.
    ANALYSIS
    In his opening appellate brief, Mr. Sanchez-Gallegos argued that the district
    court erred by: (1) denying his motion to suppress the Mexican birth certificates
    found in his vehicle and the money found on his person; (2) denying his motion to
    suppress his initial allegedly incriminatory statement and his subsequent
    statements; (3) denying his motion to strike prejudicial surplusage from the
    superseding indictment; and (4) admitting a list of telephone numbers as a
    recorded recollection under Federal Rule of Evidence 803(5).
    At oral argument, characterizing the other arguments as “silly” and
    “clutter,” counsel for Mr. Sanchez-Gallegos 3 narrowed the contentions on appeal
    3
    A prior lawyer for Mr. Sanchez-Gallegos, and not his counsel who
    (continued...)
    -7-
    to a single “meritorious” issue—viz., whether the district court should have
    suppressed Mr. Sanchez-Gallegos’s first allegedly incriminatory statement 4
    because law enforcement failed to inform Mr. Sanchez-Gallegos of his Miranda
    rights prior to questioning him. I appreciate defense counsel’s candor in
    winnowing the body of issues for our review. However, I ultimately conclude
    that the district court did not err in denying Mr. Sanchez-Gallegos’s motion to
    suppress his initial statement to Agent Gonzalez because Mr. Sanchez-Gallegos
    was not in custody when he made the statement and, therefore, Miranda did not
    apply. See United States v. Perdue, 
    8 F.3d 1455
    , 1463 (10th Cir. 1993) (“[T]wo
    requirements must be met before Miranda is applicable; the suspect must be in
    ‘custody,’ and the questioning must meet the legal definition of ‘interrogation.’”);
    see also United States v. Hudson, 
    210 F.3d 1184
    , 1186, 1190–93 (10th Cir. 2000)
    (discussing the impact of the unique context of a fixed border checkpoint on the
    analysis of the meaning of “custodial” under Miranda).
    “In considering a district court’s denial of a motion to suppress, this court
    reviews factual findings for clear error, viewing the evidence in the light most
    favorable to the government, and reviews legal conclusions de novo.” United

    States v. Rogers, 
    391 F.3d 1165
    , 1169 (10th Cir. 2004)) (internal quotation marks
    omitted). We have explained:
    Whether a person is in custody for Miranda purposes depends on
    the type of the encounter with police. Of the three types of
    police-citizen encounters—voluntary cooperation, an
    investigatory detention under Terry v. Ohio, 
    392 U.S. 1
    , 
    88 S. Ct. 1868
    , 
    20 L. Ed. 2d 889
     (1968), and a formal arrest—Miranda’s
    custody element is triggered only in situations associated with
    formal arrests. In other words, “[c]ase law is well established
    that a defendant is not in custody under either of the first two
    encounters and therefore Miranda warnings need not usually be
    given.”
    Jones, 
    523 F.3d at 1239
     (alteration in original) (quoting United States v. Griffin, 
    7 F.3d 1512
    , 1516 (10th Cir. 1993)).
    The Supreme Court explained in Miranda that an individual is “in custody”
    if he is “deprived of his freedom of action in any significant way.” Miranda v.
    Arizona, 
    384 U.S. 436
    , 444 (1966). Determining whether Mr. Sanchez-Gallegos
    was in custody for Miranda purposes “flows from our seminal inquiry: ‘whether a
    reasonable person in [Mr. Sanchez-Gallegos’s] position would have understood
    [his] freedom of action to have been restricted to a degree consistent with formal
    arrest.’” Lamy, 
    521 F.3d at 1263
     (second alteration in original) (quoting United
    States v. Revels, 
    510 F.3d 1269
    , 1275 (10th Cir. 2007)). “We therefore must
    determine whether ‘a reasonable [person] in the suspect’s position would have
    understood [the] situation . . . as the functional equivalent of formal arrest.’”
    United States v. Chee, 
    514 F.3d 1106
    , 1112 (10th Cir. 2008) (alterations in
    -10-
    original) (quoting Berkemer v. McCarty, 
    468 U.S. 420
    , 442 (1984)). A reasonable
    person “does not have a guilty state of mind and does not have peculiar mental or
    emotional conditions that are not apparent to the questioning officer.” Hudson,
    
    210 F.3d at 1190
     (quoting United States v. Erving L., 
    147 F.3d 1240
    , 1246 (10th
    Cir. 1998)) (internal quotation marks omitted).
    This is an objective, fact-intensive inquiry that focuses on the totality of the
    circumstances. See id.; see also Jones, 
    523 F.3d at 1239
    ; Griffin, 
    7 F.3d at 1518
    .
    “We thus avoid hard line rules and instead allow several non-exhaustive factors to
    guide us.” Jones, 
    523 F.3d at 1240
    . The relevant factors include: “(1) whether
    the circumstances demonstrated a police-dominated atmosphere; (2) whether the
    nature and length of the officers’ questioning was accusatory or coercive; and (3)
    whether the police made [Mr. Sanchez-Gallegos] aware that [he] was free to
    refrain from answering questions, or to otherwise end the interview.” Revels, 
    510 F.3d at 1275
    .
    Indications that an atmosphere is police-dominated
    may include whether the suspect was separated from his family
    and isolated in a nonpublic questioning room, whether there was
    the threatening presence of several officers, whether there was
    any display of weapons or physical contact with the suspect, and
    whether the officer’s language and tone indicated that
    compliance might be compelled.
    Chee, 
    514 F.3d at
    1113 (citing Griffin, 
    7 F.3d at
    1518–19).
    -11-
    “Although these factors are useful, we emphasize that we must look to the
    totality of the circumstances and consider the police-citizen encounter as a whole,
    rather than picking some facts and ignoring others.” Jones, 
    523 F.3d at 1240
    .
    I also must emphasize that context is key in deciding whether Mr. Sanchez-
    Gallegos was in custody during his encounter with the Border Patrol agents. The
    context here is a fixed border checkpoint. As we explained in Hudson, “[t]he
    Supreme Court has concluded that a stop at a fixed border checkpoint constitutes
    a Fourth Amendment seizure because a reasonable person would not believe [he]
    is free to leave.” 5 
    210 F.3d at
    1190–91 (citing United States v. Martinez-Fuerte,
    
    428 U.S. 543
    , 556 (1976)). However, “a Fourth Amendment seizure does not
    necessarily render a person in custody for purposes of Miranda.” 
    Id.
     (quoting
    United States v. Bengivenga, 
    845 F.2d 593
    , 598 (5th Cir. 1988) (en banc))
    (internal quotation marks omitted). More specifically, a number of courts,
    including our own, have recognized the important distinction between a Fourth
    Amendment seizure and Miranda’s custody requirement, and have held that while
    a routine stop at a fixed border checkpoint may be a Fourth Amendment seizure,
    it is not custodial for Miranda purposes. 
    Id.
     (citing United States v. Fernandez-
    5
    As long as the border checkpoint stop comports with the
    requirements set out by this court in United States v. Massie, 
    65 F.3d 843
    , 847–48
    (10th Cir. 1995), such a seizure is reasonable and consistent with the dictates of
    the Fourth Amendment.

    74 F.3d 1117
    , 1120 (11th Cir. 1996)).
    The unique context of fixed border checkpoint stops is revealed by the
    different legal principles applicable to them. For example, “[a]t a fixed
    checkpoint, . . . border patrol agents may stop, briefly detain, and question
    individuals without any individualized suspicion that the individuals are engaged
    in criminal activity.” Massie, 
    65 F.3d at 847
    ; accord United States v. Forbes, 
    528 F.3d 1273
    , 1277–78 (10th Cir. 2008) (discussing the “well-established principles
    applicable to border checkpoints and canine searches”). Such stops must be
    “brief and unintrusive” and the questioning “reasonably related” to the duties of
    the Border Patrol. Massie, 
    65 F.3d at 848
    . “Further detention of an individual
    beyond the scope of a routine checkpoint stop must be based upon reasonable
    suspicion, consent, or probable cause.” 
    Id.
     However, “border patrol agents have
    virtually unlimited discretion to refer cars to the secondary inspections area,”
    Forbes, 
    528 F.3d at 1277
     (quoting United States v. Sanders, 
    937 F.2d 1495
    , 1499
    (10th Cir. 1991)) (internal quotation marks omitted), and “may make such
    referrals without any particularized suspicion of criminal activity,” 
    id.
    In addition, agents are free to conduct canine searches at the border “so
    long as the vehicles and their occupants are otherwise lawfully detained at the
    time of the inspection.” 
    Id.
     Canine inspections are permissible in the absence of
    individual suspicion and without the consent of the occupants of the vehicle. See
    -13-
    Massie, 
    65 F.3d at 848
    ; see also United States v. Williams, 
    403 F.3d 1203
    , 1207
    (10th Cir. 2005) (“A canine sniff on the exterior of a vehicle during a lawful
    traffic stop does not implicate legitimate privacy interests.”). Finally, a canine’s
    alert to the presence of contraband in a vehicle during its exterior sniff gives law
    enforcement officers probable cause to search the interior of the vehicle. See
    United States v. Rosborough, 
    366 F.3d 1145
    , 1152 (10th Cir. 2004); United States
    v. Ludwig, 
    10 F.3d 1523
    , 1527–28 (10th Cir. 1993).
    In sum, “a routine stop at a fixed border checkpoint, i.e., a stop within the
    parameters set forth by this court in Massie” and related cases, as outlined above,
    “is not custodial and Miranda warnings are not necessary.” Hudson, 
    210 F.3d at 1191
    . This rule of law is animated by our view that “no reasonable person
    detained during a routine border stop could believe that her freedom was
    restrained to the degree associated with formal arrest.” 
    Id.
     Given the heightened
    security restrictions that the Sovereign routinely and necessarily enforces at fixed
    border checkpoints, “[w]e stress that events which might be enough often to
    signal ‘custody’ away from the border will not be enough to establish ‘custody’ in
    the context of entry into the country.” Moya, 
    74 F.3d at 1120
    .
    Mr. Sanchez-Gallegos contends that the district court erred in denying his
    motion to suppress the first statement that he made to Agent Gonzalez because he
    had not been advised of his Miranda rights at the time he made the statement.
    The government counters that no Miranda advisement was necessary because Mr.
    -14-
    Sanchez-Gallegos’s interaction with the Border Patrol agents did not rise to the
    level of a custodial interrogation. I believe that the government has the better
    argument in this case.
    Here, the district court properly concluded that Mr. Sanchez-Gallegos was
    not subjected to custodial interrogation. While Mr. Sanchez-Gallegos was not
    informed of his right to terminate the encounter, the nature of the pre-Miranda
    questioning was neither prolonged nor accusatory. See Jones, 
    523 F.3d at 1240
    (explaining that prolonged and accusatory questioning can create a coercive
    environment); see also Hudson, 
    210 F.3d at 1191
     (“[Q]uestioning at the border
    must rise to a distinctly accusatory level before it can be said that a reasonable
    person would feel restraints on his ability to roam to the degree associated with
    formal arrest.” (quoting Moya, 
    74 F.3d at 1120
    ) (internal quotation marks
    omitted)).
    The exchange that prompted Mr. Sanchez-Gallegos’s first allegedly
    incriminatory statement was extremely brief. See Hudson, 
    210 F.3d at 1192
    (noting that “[t]he questions were asked over a relatively brief ten-minute time
    period”); cf. Massie, 
    65 F.3d at 849
     (“We further conclude the agents’ continued
    detention and questioning of Defendants did not exceed the confines of a routine
    checkpoint stop. The agents’ questioning lasted only eight to eleven
    minutes . . . .”); United States v. Sukiz-Grado, 
    22 F.3d 1006
    , 1008–09 (10th Cir.
    1994) (“The questions that the agent asked Mr. Sukiz during his two-minute
    -15-
    detention at the primary inspection area clearly fall within the ambit of routine
    inquiry or were justified by the suspicious circumstances observed by the
    agent.”).
    Before Mr. Sanchez-Gallegos made his incriminating statement, Agent
    Gonzalez had explained that he was concerned that there were children attempting
    to circumvent the checkpoint by traveling through the desert. Agent Gonzalez
    asked Mr. Sanchez-Gallegos about the large amount of American and Mexican
    currency found in his pocket during the consensual pat-down search and the
    Mexican birth certificates found in his vehicle. 6 In response, Mr. Sanchez-
    Gallegos admitted that the money was “payment to take some children to . . .
    Chicago.” R., Vol. III, at 29.
    6
    Agent Gonzalez explained at the suppression hearing that the
    following discussion prompted Mr. Sanchez-Gallegos’s first allegedly
    incriminatory statement:
    I asked him about all the inconsistencies that we had found, and
    I told him about the fact that he had lied to me about the travel
    plans, that he had told me he was a U.S. citizen, that he had all
    this money that he couldn’t explain to me how he got it, and that
    he had some birth certificates for children.
    I told him that I believed there was a group of children
    walking around the checkpoint and that my concern was that, if
    they were, then they could be exposed to the elements and
    maybe, as I have seen before, die in the desert.
    R., Vol. III, at 28.
    -16-
    While it is true that Mr. Sanchez-Gallegos was removed from his vehicle
    and asked to wait in the Border Patrol checkpoint office, Mr. Sanchez-Gallegos
    consented to every progressive step in his encounter with Agent Gonzalez leading
    up to the questioning that elicited his allegedly incriminatory response. And there
    has been no suggestion by Mr. Sanchez-Gallegos that this consent was coerced or
    illegally obtained. First, despite not needing Mr. Sanchez-Gallegos’s permission
    to refer him to the secondary checkpoint, see Forbes, 
    528 F.3d at 1277
    , Agent
    Gonzalez sought and received such permission before Mr. Sanchez-Gallegos
    moved his vehicle from the primary inspection area to the secondary inspection
    area. Second, again without needing permission, Agent Gonzalez sought and
    received Mr. Sanchez-Gallegos’s permission prior to having another Border Patrol
    Agent conduct an exterior canine sniff of the vehicle. See Williams, 
    403 F.3d at 1207
    ; Massie, 
    65 F.3d at 848
    . Finally, Agent Gonzalez sought and received Mr.
    Sanchez-Gallegos’s permission to conduct a pat-down search before having him
    wait in the checkpoint office.
    Moreover, the atmosphere cannot be described as police-dominated. See
    Chee, 
    514 F.3d at 1113
    ; Griffin, 
    7 F.3d at
    1518–19. Only two agents were
    present during the questioning. Mr. Sanchez-Gallegos was never placed in
    handcuffs. And he was never subjected to, nor threatened with, any physical
    mistreatment. See Eckhart, 
    569 F.3d at 1276
     (explaining that Miranda warnings
    were not required where the defendant “was never handcuffed or placed in a
    -17-
    police cruiser and no weapons were drawn . . . [and] the officers were polite in
    their demeanor and did not use or threaten the use of force at any time”).
    Therefore, in the context of a fixed border checkpoint search, I do not believe that
    these circumstances, viewed in the totality, suggest that Mr. Sanchez-Gallegos
    was in custody. See Hudson, 219 F.3d at 1191 (concluding that defendants were
    not in custody under similar circumstances). 7
    7
    Our analysis in Hudson is noteworthy:
    This court reaches the same conclusion even when the series of
    questions is viewed together with the fact that Hudson and Riness
    were asked to exit their vehicle during the canine search and that
    the bill of lading was not returned to Hudson. As noted above,
    there is no question that Hudson and Riness were seized. The
    real question then becomes whether these two factors, considered
    in the context of the totality of the circumstances, altered the
    circumstances of the border stop in a manner to take it outside of
    the parameters of Massie. We note that none of the agents
    involved in this case ever spoke to Hudson and Riness in a harsh
    or threatening manner or made any show of force. Hudson and
    Riness voluntarily left their vehicle and consented to the canine
    search. Hudson and Riness were never separated from each
    other, were never placed in handcuffs or a holding cell, and were
    never told they were under arrest. Although it was clear that they
    would be unable to leave because of the pendency of the canine
    search, they had specifically consented to the search.
    Accordingly, the agents’ failure to return the bill of lading at the
    time the questioning occurred is completely unremarkable.
    Considered against the totality of the circumstances in this case,
    none of the factors identified by the district court take this case
    outside of the Massie heartland.
    
    210 F.3d at
    1192–93.
    -18-
    To be sure, Mr. Sanchez-Gallegos had been at the checkpoint for as long as
    fifty minutes when he made the first allegedly incriminatory statement. However,
    this passage of time must be viewed in the context of (1) his consent, and (2) the
    fact that Mr. Sanchez-Gallegos was not questioned throughout this entire period.
    Mr. Sanchez-Gallegos consented to each governmental action that resulted in the
    delay. Furthermore, during a considerable portion of this time, Agent Gonzalez
    was either engaged in border-enforcement duties unrelated to Mr. Sanchez-
    Gallegos or was running criminal and immigration history checks related to Mr.
    Sanchez-Gallegos but not interrogating him. Mr. Sanchez-Gallegos’s first
    allegedly incriminatory statement came in response to a very brief period of
    questioning by Agent Gonzalez. Consequently, on the facts of this case, I do not
    believe that Massie’s limitation to a “brief” period of questioning was
    contravened. Compare United States v. Chavira, 
    614 F.3d 127
    , 134 (5th Cir.
    2010) (“Under all these circumstances, thirty to forty minutes of increasingly
    accusatory questioning would indicate to the reasonable person in Chavira’s
    situation that her freedom had been restrained to the degree associated with
    formal arrest.”), with United States v. Harrell, 
    894 F.2d 120
    , 124 (5th Cir. 1990)
    (“[W]e cannot say that a 60–75 minute interrogation is per se custodial, especially
    where the detainee offers the incriminating statements early in the detention.
    Some measure of investigatorial questioning is permissible without invoking
    Miranda concerns.”).
    -19-
    Mr. Sanchez-Gallegos was not in custody when he initially admitted to
    receiving money to transport children to Chicago because his freedom was not
    curtailed to the degree associated with a formal arrest. Therefore, in the context
    of a fixed border checkpoint search, and under the unique circumstances of this
    case—that included Mr. Sanchez-Gallegos’s repeated grants of consent which
    extended his encounter with law enforcement—Miranda warnings were not
    required. Thus, in my view, the district court did not err in denying the motion to
    suppress.
    -20-
    No. 09-2146, United States v. Sanchez-Gallegos
    BRISCOE, Chief Judge, concurring:
    I agree with the ultimate conclusion that Sanchez-Gallegos was not in
    custody when he made his initial incriminating statements and that Miranda,
    therefore, does not apply. Thus, I agree that the district court did not err in
    denying the motion to suppress these incriminating statements. However, in my
    view, Sanchez-Gallegos’s encounter exceeded the parameters for a routine stop at
    a fixed border checkpoint established in United States v. Massie, 
    65 F.3d 843
    (10th Cir. 1995). Nonetheless, I conclude that Sanchez-Gallegos was not in
    custody for purposes of Miranda based on the totality of the circumstances
    presented.
    I
    In United States v. Hudson, this court established that “a routine stop at a
    fixed border checkpoint, i.e., a stop within the parameters set forth by this court
    in Massie, is not custodial and Miranda warnings are not necessary.” Hudson,
    
    210 F.3d 1184
    , 1191 (10th Cir. 2000). Thus, the first question to address is
    “whether the facts of this case take it outside of the Massie heartland.” 
    Id.
     I
    conclude that Sanchez-Gallegos’s encounter with the border patrol agents
    exceeded the Massie parameters for a routine stop at a fixed border checkpoint.
    In Massie, this court defined a routine fixed border checkpoint stop as a
    “brief and unintrusive” encounter where “a border patrol agent may ask questions
    reasonably related to his duties and explore suspicious circumstances.” 
    65 F.3d at 848
     (emphasis added). Further, without exceeding the confines of a routine fixed
    border checkpoint stop, an agent may direct individuals to a secondary checkpoint
    and can pursue inquiries at the secondary location regarding “vehicle ownership,
    cargo, destination, and travel plans, and . . . any suspicious circumstances . . .
    observed, as long as the detention remain[s] brief and unintrusive.” 
    Id. at 849
    (internal quotation marks and citation omitted). Thus, in Massie, this court
    characterized as a routine checkpoint stop an encounter at a fixed border
    checkpoint involving inquiries that “lasted only eight to eleven minutes from the
    time Defendants were stopped at primary to the moment the dog alerted on the
    trunk” and that concerned “citizenship, vehicle ownership, vehicle contents,
    destination, and travel plans.” 
    Id.
    Sanchez-Gallegos’s stop at the fixed border checkpoint exceeded the
    Massie parameters due the length and intrusiveness of the encounter. Initially,
    the encounter began as a routine fixed border checkpoint stop. Specifically, the
    border patrol agents asked routine questions and referred Sanchez-Gallegos to the
    secondary checkpoint, where he consented to a canine search of his vehicle. See
    Hudson, 
    210 F.3d at
    1192–93. However, after the dog alerted to the vehicle,
    Sanchez-Gallegos was asked to proceed to the secondary checkpoint office and he
    submitted to a consensual pat-down search for the agents’ safety, which revealed
    approximately eight thousand dollars in his pocket. While Sanchez-Gallegos
    -2-
    waited in the secondary checkpoint office, border patrol agents searched the
    interior of his vehicle, uncovering six Mexican birth certificates. At this point,
    after Sanchez-Gallegos had been detained at the checkpoint for approximately
    forty to fifty minutes, the agents engaged in the questioning that elicited the
    incriminating statements at issue in this case. I conclude that this encounter
    necessarily extended beyond the confines of a brief, unintrusive detention as
    required in Massie for a routine stop at a fixed border checkpoint.
    II
    Even though the encounter exceeded the parameters of Massie, this does
    not dictate the conclusion that Sanchez-Gallegos was in custody for purposes of
    Miranda. See Hudson, 
    210 F.3d at
    1191 n.8 (“[T]his court does not mean to
    suggest that every time a border stop evolves beyond the routine parameters set
    forth in Massie a custodial situation is created.”). Rather, this court must still
    consider the totality of the circumstances presented to determine “whether a
    reasonable person in [the suspect’s] position would have understood [his] freedom
    of action to have been restricted to a degree consistent with formal arrest.”
    United States v. Revels, 
    510 F.3d 1269
    , 1275 (10th Cir. 2007). This inquiry
    involves examination of the following non-exhaustive factors: “(1) whether the
    circumstances demonstrated a police-dominated atmosphere; (2) whether the
    nature and length of the officers’ questioning was accusatory or coercive; and (3)
    -3-
    whether the police made [the suspect] aware that []he was free to refrain from
    answering questions, or to otherwise end the interview.” 
    Id.
    Examining the totality of the circumstances presented in this case, I
    conclude that Sanchez-Gallegos was not in custody for the purposes of Miranda.
    First, Sanchez-Gallegos was not questioned in a police-dominated atmosphere.
    Specifically, only two border patrol agents were present during the questioning
    that elicited the incriminating statements. Further, while the questioning occurred
    in the secondary checkpoint office, Sanchez-Gallegos was directed to that
    location during the search of his vehicle and after he submitted to a consensual
    pat-down search. See United States v. Butler, 
    249 F.3d 1094
    , 1100–01 (9th Cir.
    2001) (“[T]he mere detention of a person in a border station’s security office from
    which he or she is not free to leave, while a search of a vehicle occurs, is not
    ‘custody’ for [Miranda] purposes.”).
    Second, the nature and length of the officers’ questioning was not
    accusatory or coercive. Specifically, there is no indication that the border patrol
    agents spoke in a threatening or accusatory tone and the agents did not display
    their weapons during the inquiry. Further, Sanchez-Gallegos was not placed in
    handcuffs or a holding cell, he was not told that he was under arrest, and he was
    not questioned for a long period of time. In fact, the questioning that elicited the
    incriminating statements at issue in this case was brief. However, Sanchez-
    Gallegos was not informed of his right to terminate the encounter with the agents.
    -4-
    Nevertheless, when considering the totality of the circumstances, I conclude that
    Sanchez-Gallegos was not in custody for the purposes of Miranda. See United
    States v. Jones, 
    523 F.3d 1235
    , 1240 (10th Cir. 2008) (“Although these factors are
    useful, we emphasize that we must look to the totality of the circumstances and
    consider the police-citizen encounter as a whole, rather than picking some facts
    and ignoring others.”).
    As Sanchez-Gallegos was not in custody for the purposes of Miranda, I also
    conclude that the district court did not err in denying the motion to suppress his
    initial incriminating statements.
    -5-
    No. 09-2146, United States v. Sanchez-Gallegos
    EBEL, Circuit Judge, concurring.
    I agree with both of my respected panel members that Mr. Sanchez-
    Gallegos' conviction should be affirmed. However, I part ways with the majority
    in its conclusion that Mr. Sanchez-Gallegos was not in custody when he made his
    initial incriminating statement to Border Patrol Agent Gonzalez. In my view, Mr.
    Sanchez-Gallegos was in custody at that point, and it was incumbent upon the
    agents to warn him of his rights under Miranda v. Arizona, 
    384 U.S. 436
     (1966),
    prior to that interrogation. However, I believe that the officers' administration of
    the Miranda warning after that initial statement was sufficient to advise Mr.
    Sanchez-Gallegos of his rights, and to render the statements made after the
    warning—the vast bulk of the statements that led to Mr. Sanchez-Gallegos'
    arrest—admissible. Thus, I believe that while the admission of the single pre-
    Miranda statement was erroneous, the error was in fact harmless. Accordingly, I
    agree that Mr. Sanchez-Gallegos’ conviction should be affirmed.
    I.   Mr. Sanchez-Gallegos Was In Custody at the Time of His Initial Statement
    The majority is correct that “a routine stop at a fixed border checkpoint, i.e.,
    a stop within the parameters set forth by this court in [United States v. Massie, 
    65 F.3d 843
     (10th Cir. 1995)], is not custodial and Miranda warnings are not
    necessary.” United States v. Hudson, 
    210 F.3d 1184
    , 1191 (10th Cir. 2000). In
    Massie, we held that “during a routine fixed-checkpoint stop a border patrol agent
    may ask questions reasonably related to his duties and explore suspicious
    circumstances, but must be brief and unintrusive.” 
    65 F.3d at 848
     (emphasis
    added). In that case, we determined that border patrol agents' detention and
    questioning of defendants were sufficiently brief and unintrusive so as not to
    exceed the confines of a routine checkpoint stop where the “agents' questioning
    lasted only eight to eleven minutes from the time Defendants were stopped at [the]
    primary [inspection area] to the moment the dog alerted on the trunk,” and where
    “[t]he agents questioned Defendants about citizenship, vehicle ownership, vehicle
    contents, destination, and travel plans.” 
    Id. at 849
    .
    I agree with Chief Judge Briscoe’s opinion that the facts of this case “take it
    outside of the Massie heartland.” Hudson, 
    210 F.3d at 1191
    . First, Mr. Sanchez-
    Gallegos had been detained for approximately forty to fifty minutes before Agent
    Gonzalez asked the questions that elicited Mr. Sanchez-Gallegos' initial
    incriminating statement. Second, although consensual, Mr. Sanchez-Gallegos was
    directed to a secondary checkpoint, subjected to a canine sniff of his vehicle, and
    patted down. The interior of his vehicle was then searched by border patrol agents
    and he was questioned in a secondary checkpoint office. In addition, Agent
    Gonzalez's questions that elicited Mr. Sanchez-Gallegos' testimony were anything
    but unintrusive. As Agent Gonzalez testified at the suppression hearing:
    I asked him about all the inconsistencies that we had found, and I
    told him about the fact that he had lied to me about the travel
    -2-
    plans, that he had told me he was a U.S. citizen, that he had all this
    money that he couldn't explain to me how he got it, and that he had
    some birth certificates for children. I told him that I believed there
    was a group of children walking around the checkpoint and that my
    concern was that, if they were, they could be exposed to the
    elements and maybe, as I have seen before, die in the desert.
    R., vol. III at 28. Under these circumstances, the detention and questioning of
    Mr. Sanchez-Gallegos exceeded the parameters set forth in Massie.
    Chief Judge Briscoe nonetheless concludes that Mr. Sanchez-Gallegos was
    not in custody for the purposes of Miranda under the totality of circumstances
    presented here. To determine whether a suspect is in custody for the purposes of
    Miranda, we “must decide whether a reasonable person in [the suspect's] position
    would have understood [his] freedom of action to have been restricted to a degree
    consistent with formal arrest.” United States v. Revels, 
    510 F.3d 1269
    , 1275
    (10th Cir. 2007). “Several relevant factors inform our fact-specific analysis,
    including: (1) whether the circumstances demonstrated a police-dominated
    atmosphere; (2) whether the nature and length of the officers' questioning was
    accusatory or coercive; and (3) whether the police made [the suspect] aware that
    [he] was free to refrain from answering questions, or to otherwise end the
    interview.” 
    Id.
     I believe that this analysis inevitably leads to the conclusion that
    Mr. Sanchez-Gallegos was in custody.
    First, the circumstances demonstrate a police-dominated atmosphere. Mr.
    Sanchez-Gallegos was removed from his vehicle, taken to a separate checkpoint
    office, and interrogated in the presence of two border patrol agents, while two
    -3-
    other agents searched his vehicle. Chief Judge Briscoe believes that this does not
    suffice to create a police-dominated atmosphere because (1) Mr. Sanchez-
    Gallegos was directed to the secondary checkpoint office during the search of his
    vehicle and only after he submitted to a consensual pat-down search, and (2) only
    two border patrol agents were present during the initial interrogation. I
    respectfully disagree. First, as Judge Holmes recognizes, the search of Mr.
    Sanchez-Gallegos' vehicle was completed before he was subjected to the
    interrogation that elicited his incriminating statement. Second, it is unclear why
    two border patrol agents questioning Mr. Sanchez-Gallegos alone in a border
    checkpoint office is insufficient to constitute a police-dominated atmosphere.
    Moreover, more than two agents were present at the checkpoint, as at least two
    others searched Mr. Sanchez-Gallegos' vehicle. Therefore, I find that this factor
    supports a conclusion that Mr. Sanchez-Gallegos was in custody at the time of the
    interrogation.
    The second factor— whether the nature and length of the officers'
    questioning was accusatory or coercive—is a closer call. On the one hand, I think
    it is an inescapable conclusion that the agents' questioning was accusatory. Agent
    Gonzales not only accused Mr. Sanchez-Gallegos of lying and giving inconsistent
    statements, but Gonzales showed Mr. Sanchez-Gallegos the birth certificates and
    told him that a group of children “could be exposed to the elements and maybe, as
    -4-
    I have seen before, die in the desert.” R., vol. III at 28. I fail to see how such
    questioning is not plainly accusatory.
    On the other hand, as my respected panel members point out, Mr. Sanchez-
    Gallegos was not subjected to or threatened with any physical mistreatment, was
    not placed in handcuffs or a holding cell, and was not questioned for a long
    period of time before the Miranda warning was given. Under these
    circumstances, the agent's questioning, while accusatory, did not rise to the level
    of coercion. Compare United States v. Eckhart, 
    569 F.3d 1263
    , 1276 (10th Cir.
    2009) (finding stop to be noncoercive where defendant “was never handcuffed or
    placed in a police cruiser and no weapons were drawn” and “the officers were
    polite in their demeanor and did not use or threaten the use of force at any time”),
    United States v. Lamy, 
    521 F.3d 1257
    , 1263 (10th Cir. 2008) (finding second
    factor not met where “the interview lasted for about an hour and . . . there was no
    indication that the questioning was unusually confrontational”), and United States
    v. Bennett, 
    329 F.3d 769
    , 775 (10th Cir. 2003) (finding that coercive factors were
    not present where police did not restrain the defendant while questioning him and
    told him he was not under arrest), with United States v. Perdue, 
    8 F.3d 1455
    ,
    1464, 1467 (10th Cir. 1993) (finding “overwhelmingly” coercive atmosphere
    where defendant “was forced out of his car and onto the ground at gunpoint” and
    then questioned by officers “while police helicopters hovered above” and “while
    -5-
    the officers kept their guns drawn on him and his pregnant fiancée”).
    Accordingly, this factor cuts both ways in the analysis.
    Finally, as the majority acknowledges, Mr. Sanchez-Gallegos was never
    informed by the agents that he was free to end the interview. This weighs
    significantly in favor of finding custodial interrogation in this case. See Revels,
    
    510 F.3d at 1276
     (finding that the suspect was in custody for Miranda purposes
    where “the police never indicated to [the suspect] that she was free to leave or
    otherwise at liberty to terminate the police questioning”); United States v. Griffin,
    
    7 F.3d 1512
    , 1518 (10th Cir. 1993) (“[T]he lack of a police advisement that the
    suspect is at liberty to decline to answer questions or free to leave is a significant
    indication of a custodial detention.”).
    Under the totality of the circumstances described above, I conclude that Mr.
    Sanchez-Gallegos was in custody when he was questioned by Agent Gonzalez,
    and therefore that the failure to give Mr. Sanchez-Gallegos a Miranda warning
    rendered his initial statement inadmissible. However, I do not believe that this
    error warrants reversal. As discussed below, the subsequent Miranda warning
    given to Mr. Sanchez-Gallegos was effective to render his later statements
    admissible, and thus the district court's admission of Mr. Sanchez-Gallegos' pre-

    II.   The District Court Did Not Err in Admitting Mr. Sanchez-Gallegos'
    Post-Miranda Statements.
    After Mr. Sanchez-Gallegos made the initial incriminating statement, Agent
    Gonzalez read Mr. Sanchez-Gallegos his Miranda rights and Mr. Sanchez-
    Gallegos waived his right to remain silent. He then proceeded to confess to
    involvement with the crime, and even went so far as to call Victor so that ICE
    agents could find the children. The question, then, becomes whether the Miranda
    warning given after the incriminating statement sufficed to render the post-
    warning statements admissible, notwithstanding the prior violation of Mr.
    Sanchez-Gallegos' Miranda rights.
    In Missouri v. Seibert, the Supreme Court in a fragmented opinion found that a
    Miranda warning given mid-interrogation pursuant to a “question-first tactic” was
    insufficient to render the defendant's later statements admissible. 
    542 U.S. 600
    ,
    617 (2004). The four-justice plurality set forth the following five “relevant facts
    that bear on whether Miranda warnings delivered midstream could be effective”:
    [1] the completeness and detail of the questions and answers
    in the first round of interrogation, [2] the overlapping content
    of the two statements, [3] the timing and setting of the first
    and the second, [4] the continuity of police personnel, and
    [5] the degree to which the interrogator's questions treated
    the second round as continuous with the first.
    
    Id. at 615
    .
    In a concurring opinion, however, Justice Kennedy argued for “a
    much narrower test applicable only to the infrequent case . . . in which
    -7-
    the two-step interrogation technique was used in a calculated way to
    undermine the Miranda warning.” 
    Id. at 622
     (Kennedy, J., concurring
    in the judgment). Where a two-step interrogation technique was not so
    used, Justice Kennedy believed that “[t]he admissibility of postwarning
    statements should continue to be governed by the principles of [Oregon
    v. Elstad 
    470 U.S. 298
    (1985)].” 
    Id.
     In Elstad, the Court concluded that
    “absent deliberately coercive or improper tactics in obtaining the initial
    statement, the mere fact that a suspect has made an unwarned admission
    does not warrant a presumption of compulsion,” and thus “[a]
    subsequent administration of Miranda warnings to a suspect who has
    given a voluntary but unwarned statement ordinarily should suffice to
    remove the conditions that precluded admission of the earlier
    statement.” Elstad, 
    470 U.S. at 314
    . Accordingly, the Court held that
    statements made after a voluntary Miranda waiver could be admissible
    as long as the pre-Miranda statements were also uncoerced. 
    Id. at 318
    .
    “[A] suspect who has once responded to unwarned yet uncoercive
    questioning is not thereby disabled from waiving his rights and
    confessing after he has been given the requisite Miranda warnings.” 
    Id.
    In United States v. Carrizales-Toldeo, we noted that determining
    the holding of Siebert is not easy in light of the fragmented nature of
    the opinion. 
    454 F.3d 1142
    , 1151 (10th Cir. 2006). We declined to
    -8-
    determine whether the four-justice plurality or Justice Kennedy's
    concurrence reflects the holding of Seibert, and instead applied both
    tests to the facts of that case. 
    Id.
     However, I would hold that Justice
    Kennedy's concurrence, as the narrowest grounds for the Supreme
    Court's decision to suppress, represents the holding of Seibert. 1
    Under the test advanced by Justice Kennedy, Mr. Sanchez-
    Gallegos' post-Miranda statements are admissible. The record does not
    reflect that a “two-step interrogation technique was used in a calculated
    way to undermine the Miranda warning.”

    The majority of our sister circuits have reached the same conclusion. See
    United States v. Capers, No. 07-1830-cr, 
    2010 U.S. App. LEXIS 24516
    , at *14
    (2d Cir. Dec. 1, 2010) (noting that the Second Circuit applies Justice Kennedy's
    approach); United States v. Torres-Lona, 
    491 F.3d 750
    , 758 (8th Cir. 2007) (“We
    treat Justice Kennedy's concurrence as controlling since it provided the fifth vote
    necessary for a majority and since it was decided on narrower grounds than the
    plurality opinion.”); United States v. Street, 
    472 F.3d 1298
    , 1313 (11th Cir. 2006)
    (“Because Seibert is a plurality decision and Justice Kennedy concurred in the
    result on the narrowest grounds, it is his concurring opinion that provides the
    controlling law.”); United States v. Courtney, 
    463 F.3d 333
    , 338 (5th Cir. 2006)
    (“[W]e find Seibert's holding in Justice Kennedy's opinion concurring in the
    judgment.”); United States v. Williams, 
    435 F.3d 1148
    , 1158 (9th Cir. 2006)
    (finding that Justice Kennedy's “narrower test . . . represents Seibert's holding”);
    United States v. Kiam, 
    432 F.3d 524
    , 532 (3d Cir. 2006) (“This Court applies the
    Seibert plurality opinion as narrowed by Justice Kennedy.”); United States v.
    Mashburn, 
    406 F.3d 303
    , 309 (4th Cir. 2005) (“Justice Kennedy's opinion
    therefore represents the holding of the Seibert Court: The admissibility of
    postwarning statements is governed by Elstad unless the deliberate 'question-first'
    strategy is employed.”). But see United States v. Heron, 
    564 F.3d 879
    , 884 (7th
    Cir. Ill. 2009) (“Although Justice Kennedy provided the crucial fifth vote for the
    majority, we find it a strain at best to view his concurrence taken as a whole as
    the narrowest ground on which a majority of the Court could agree. . . . Justice
    Kennedy's intent-based test was rejected by both the plurality opinion and the
    dissent in Seibert.”).

    concurring in the judgment). Thus, we look to Elstad, which held that
    later statements could be admissible as long as the pre-Miranda
    statements were uncoerced. Elstad, 
    470 U.S. at 318
    . As discussed
    above, while the agent's pre-warning questioning was accusatory, it did
    not rise to the level of coercion such that Mr. Sanchez-Gallegos' post-
    Miranda statements are inadmissible under Elstad. Accordingly, I find
    that Mr. Sanchez-Gallegos' statements made after receiving the Miranda
    warning were properly admitted. 2

    I acknowledge that the conclusion might be different under the plurality's
    test in Seibert. This test “concern[s] the relationship between the first and second
    interrogations.” Carrizales-Toldeo, 
    454 F.3d at 1150
    . In this case, there was
    little distinction in the two phases of questioning. Although questions and
    answers became more specific during the second interrogation, the content clearly
    overlapped, as both interrogations concerned the transportation of children.
    Moreover, there was no break in the timing, setting, or personnel of the two
    interrogations. Finally, the questioning treated the second round as continuous
    with the first, as the second followed immediately upon the first and followed up
    on Mr. Sanchez-Gallegos' pre-Miranda statement.

    III. The Admission of Mr. Sanchez-Gallegos' Pre-Miranda
    Statement Was Harmless Error
    Although the district court erred in admitting Mr. Sanchez-Gallegos' pre-
    Miranda statement, this Court may nevertheless affirm his conviction if that error
    was harmless. “The Supreme Court has applied harmless error analysis to a wide
    range of constitutional errors, including the admission of unlawful confessions.”
    Perdue, 
    8 F.3d at 1469
     (internal quotation marks omitted). “A constitutional error
    is harmless and may be disregarded if it appears beyond a reasonable doubt that
    the error complained of did not contribute to the verdict obtained.” United States
    v. Holly, 
    488 F.3d 1298
    , 1307 (10th Cir. 2007) (internal quotation marks
    omitted).
    As a general rule, it is the government's burden to prove that an error was
    harmless. See United States v. Lott, 
    310 F.3d 1231
    , 1251 (10th Cir. 2002) (citing
    United States v. Miller, 
    111 F.3d 747
    , 751 (10th Cir. 1997)). Here, the
    government failed to argue in its brief or at oral argument that the admission of
    Sanchez-Gallegos' unwarned confession at trial was harmless. “Nevertheless,
    where the government has failed to assert harmless error, this court may in its
    discretion initiate harmless error review in an appropriate case.” Holly, 
    488 F.3d at 1307
     (internal quotation marks and citation omitted). “In deciding whether to
    exercise its discretion to address harmlessness, this court considers '(1) the length
    and complexity of the record; (2) whether the harmlessness of the errors is certain
    or debatable; and (3) whether a reversal would result in protracted, costly, and
    -11-
    futile proceedings in the district court.'” 
    Id. at 1308
     (quoting United States v.
    Samaniego, 
    187 F.3d 1222
    , 1225 (10th Cir. 1999)). 3
    Considering harmless error sua sponte is appropriate in this case. As to the
    first factor, the record in this case comprises three volumes and more than 600
    pages of material, but consists primarily of transcripts. Though a long and
    complex record normally weighs against sua sponte harmless-error review
    unguided by the arguments of the parties, Samaniego, 
    187 F.3d at 1225
    , in this
    case the record, while lengthy, is relatively straightforward, as is the case against
    Mr. Sanchez-Gallegos.
    As to the second factor, even where a record is long and complex, sua
    sponte harmless-error review may be appropriate “where the certainty of the
    harmlessness is readily apparent.” Holly, 
    488 F.3d at 1308
    . Here, there can be
    little doubt that the error of admitting testimony of Sanchez-Gallegos' one-
    sentence unwarned statement was harmless. Whereas this statement was short
    and vague, in his properly admitted post-Miranda statements, Mr. Sanchez-
    Gallegos explained the situation to the officers in detail and even assisted the
    officers in finding Victor and the children. The detail and extent of the post-
    3
    As noted by the Court in Holly, we have “quite reasonably” questioned
    the relevance of the third factor. Holly, 
    488 F.3d at
    1308 n.8; Samaniego, 
    187 F.3d 1225
     n.2 (“Without eviscerating the doctrine, cost and potentially protracted
    proceedings cannot preclude reversal if an error was not harmless.”). Here, as in
    Holly, because the first two factors indicate that a sua sponte harmless-error
    review is appropriate in this case, we do not need to address the third factor.
    Holly, 
    488 F.3d at
    1308 n.8.
    -12-
    Miranda statements so vastly outweigh the pre-Miranda statement that it is
    “beyond a reasonable doubt that the error complained of did not contribute to the
    verdict obtained.” Holly, 
    488 F.3d at 1307
    . Accordingly, a sua sponte harmless-
    error review is appropriate in this case, and inexorably leads to the conclusion
    that the admission of Mr. Sanchez-Gallegos' pre-Miranda statement was harmless.
    IV.   Conclusion
    While I believe that Mr. Sanchez-Gallegos was in custody at the time he
    made the unwarned admission, the subsequent Miranda warning sufficed to make
    the later statements admissible, and in light of the substance of those later
    statements, the admission at trial of the pre-warned statement was harmless error.
    I therefore concur with the judgment of the majority.
