Before: BOGGS,** S. R. THOMAS, and FORREST, Circuit Judges.

Eduardo Alvarez, Jr. appeals the district court’s denial of his motion to 

suppress a handgun that police officers found in his friend Kristin Kalin’s car 

following an investigatory stop. The district court had jurisdiction pursuant to 18 

U.S.C. § 3231. We have jurisdiction pursuant to 28 U.S.C. § 1291. 

* This disposition is not appropriate for publication and is not precedent except as 

provided by Ninth Circuit Rule 36-3.

U.S. COURT OF APPEALS

We review de novo the district court’s denial of a motion to suppress evidence. 

United States v. Zapien, 861 F.3d 971, 974 (9th Cir. 2017). We review the factual 

findings underlying the denial for clear error. Ibid. 

We affirm. Because the parties are familiar with the factual and procedural 

history of the case, we need not recount it here.

1. Alvarez argues that the district court erred in determining that Deputy 

Kharrl had reasonable suspicion to justify an investigatory stop under Terry v. Ohio, 

392 U.S. 1 (1968), and its progeny. Assuming, without deciding, that Kharrl did not 

have reasonable suspicion to justify an investigatory stop, the discovery of Kalin’s 

warrant roughly six minutes into the encounter attenuated the illegality of the stop. 

See Utah v. Strieff, 579 U.S. 232, 243 (2016) (holding that evidence seized following 

an unlawful stop was admissible because the discovery of a valid warrant attenuated 

the illegal stop). 

2. The district court did not err in determining that the stop was not 

unconstitutionally prolonged, and thus the eventual vehicle search was valid. Of 

course, Alvarez cannot argue that he had a reasonable expectation of privacy in 

Kalin’s car. See United States v. Twilley, 222 F.3d 1092, 1095 (9th Cir. 2000). But 

he can, and does, challenge the lawfulness of his own detention. To show the district 

court erred in not suppressing the gun, Alvarez “must show that [discovering the 

evidence] was in some sense the product of his unlawful detention.” United States

v. Pulliam, 405 F.3d 782, 787 (9th Cir. 2005) (cleaned up). To that end, Alvarez 

argues that the stop was unreasonably prolonged.

Though Kharrl certainly expanded the scope of his investigation after the 

initial stop, he did so reasonably as the facts on the ground evolved. A seizure’s 

mission determines its tolerable duration. United States v. Evans, 786 F.3d 779, 785 

(9th Cir. 2015). As soon as Kharrl learned of Kalin’s outstanding warrant, his 

mission became to execute the warrant. See Strieff, 579 U.S. at 242 (noting that 

discovering a warrant compels an officer to make an arrest). Kharrl then had cause 

to prolong the stop to investigate further. See Evans, 786 F.3d at 788 (“[A]n officer 

may prolong a traffic stop if the prolongation itself is supported by independent 

reasonable suspicion.”).

The events that transpired after Kharrl discovered the warrant were both

logical and lawful. To execute the warrant, Kharrl had to ask for Kalin’s 

identification to confirm her identity. See Strieff, 579 U.S. at 241. As Kalin 

rummaged in her bag to get her ID, Kharrl heard a loud and distinctive “clink,” which 

in his training and experience implied drug paraphernalia. Roughly four minutes 

later, Kalin admitted that the sound came from a glass pipe. At this point, there was 

independent probable cause to search the car. See Maryland v. Dyson, 527 U.S. 465, 

466-67 (1999) (recognizing that police may search a car without a warrant if there 

is probable cause to believe that it contains evidence of drug activity).

The discovery of the gun was not the product of any unlawful detention of 

Alvarez. It was a product of independent probable cause—suspected drug activity 

and Kalin’s outstanding warrant. Once Kharrl had this information, Kalin was not 

going to drive the car away before a search occurred. Neither was Alvarez, who did 

not own the car or even possess a valid driver’s license. Even if Kharrl had allowed 

Alvarez to leave on foot, “the search of the car still would have occurred, and the 

gun would have been found.” Pulliam, 405 F.3d at 787.

Accordingly, the district court did not err in denying Alvarez’s motion to 

suppress. Kalin’s warrant attenuated the connection between the arguably unlawful 

stop and the seized evidence, and the police found the gun after a lawful search that 

flowed from the discovery of the warrant.

AFFIRMED.
