MEMORANDUM **
The United States appeals the district court’s order granting Carlos Martinez’s motion to suppress statements he made during a police interrogation. The district court ruled there was “no constitutional justification for the conduct of the officers” throughout the interrogation. The Government timely appealed. It argues that because Martinez was not in custody during the initial one minute and forty-six seconds of the interrogation, that portion of the interview should not have been suppressed. We have jurisdiction under 28 U.S.C. § 1291. We''agree with the Government and reverse the district court’s order.1
The Government argues for the first time on appeal that the district court should have introduced the first one minute and forty-six seconds of the interview. Limiting the inquiry to Martinez’s initial statements alters our analysis considerably. We requested supplemental briefing addressing whether the Government waived the argument that Martinez’s initial statements are admissible. In response, Martinez took the position that the Government did not waive this argument. Therefore, pursuant to this court’s waiver of waiver doctrine, we reach the merits of the Government’s newly fashioned theory. Norwood v. Vance, 591 F.3d 1062, 1068 (9th Cir.2010).
A district court’s decision on a motion to suppress evidence is reviewed de novo. United States v. Brobst, 558 F.3d 982, 995 (9th Cir.2009)., We also review de novo a district court’s custody determination for Miranda purposes. Id.
In-custody determinations are based on the totality of the circumstances. Id. (quoting United States v. Hayden, 260 F.3d 1062, 1066 (9th Cir.2001)). Relevant factors include: “(1) the language used to summon the individual; (2) the extent to which the defendant is confronted with evidence of guilt; (3) the physical surroundings of the interrogation; (4) the duration of the detention; and (5) the degree of pressure applied to detain the individual.” Id. (quoting Hayden, 260 F.3d at 1066) (internal quotation marks omitted).
We are mindful that the officers used a ruse to convince Martinez to come to the interview, but “[pjloys to mislead a suspect or lull him into a false sense of security that do not rise, to the level of compulsion or coercion to speak are not within Miranda’s concerns.” Illinois v. Perkins, 496 U.S. 292, 297, 110 S.Ct. 2394, 110 L.Ed.2d 243 (1990).
The officers did not confront Martinez with evidence of guilt during the initial statements. This weighs against the conclusion that Martinez was in custody. The questioning officer did not “adopt[ ] an aggressive, coercive, and deceptive tone,” as in cases in which this court has found interrogations to be custodial. United *660States v. Bassignani, 575 F.3d 879, 884 (9th Cir.2009).
The physical surroundings of this interrogation weigh in favor of custody. Martinez saw “at least five police cars” outside the home as he approached, the questioning took place in confined quarters — a police van — and armed and uniformed officers remained in the van during Martinez’s initial statements. Thus, “the questioning occurred in a police-dominated atmosphere where [Martinez] was effectively isolated.” See United States v. Beraun-Panez, 812 F.2d 578, 579, 582 (9th Cir.1987) (finding an interrogation custodial where two officers questioned an individual by himself, “well away from the public view”).
We are most persuaded by the fact that Martinez made the statements the Government seeks to introduce in the first one minute and forty-six seconds of the interrogation. See Brobst, 558 F.3d at 996 (indicating that questioning of “two minutes or so” weighs against custody); United States v. Gregory, 891 F.2d 732, 735 (9th Cir.1989) (interrogation deemed noncustodial, in part because it “lasted only a few minutes”). This is a far cry from cases involving extended questioning, where the sheer length of the questioning may result in undue fatigue and thus coercion. Cf. United States v. Kim, 292 F.3d 969, 977 (9th Cir.2002) (finding a “full-fledged interrogation” where suspect was questioned for at least 50 minutes and detained even longer).
The degree of pressure applied to detain Martinez does not significantly .weigh in favor of concluding the interview was custodial. The tone and tenor of the initial questioning was not intense, but police dominated the physical environment inside and outside the van and the officers did not inform Martinez that he was free to leave.
This presents a close case, made all the more difficult because the district court did not have an opportunity to make findings on the question presented by this appeal. Under the totality of the circumstances, we are persuaded that a reasonable person would not have believed he was not free to leave the interrogation in the first one minute and forty-six seconds. Martinez was not in custody when he made his initial statements, and that portion of the interview should not have been suppressed.
REVERSED and REMANDED for further proceedings consistent with this decision.
