              The Honorable Leslie E. Kobayashi, United States District Judge for
the District of Hawaii, sitting by designation.
      Defendant Ruben Ramirez-Ventura appeals his conviction for conspiracy to

distribute cocaine, challenging the district court’s denial of his suppression motion.

We have jurisdiction pursuant to 28 U.S.C. § 1291, and we affirm.

      We review de novo the denial of a motion to suppress, United States v.

Jones, 286 F.3d 1146, 1150 (9th Cir. 2002), and review a district court’s factual

findings for clear error. United States v. Berber-Tinoco, 510 F.3d 1083, 1087 (9th

Cir. 2007). We may affirm on any ground supported by the record. See United

States v. Miller, 822 F.2d 828, 833 (9th Cir. 1987).

      All parties agree that, because Ramirez was speeding, the troopers had an

independent valid basis to conduct a pretextual traffic stop, see Whren v. United

States, 517 U.S. 806, 812-13 (1996), and that the troopers could ask questions

unrelated to the purpose of the traffic stop, so long as the questioning did “not

prolong an initially lawful stop.” United States v. Turvin, 517 F.3d 1097, 1100

(9th Cir. 2008) (internal quotations omitted). Furthermore, the troopers could

prolong the traffic stop if they had reasonable suspicion to justify their questioning.

United States v. Mendez, 476 F.3d 1077, 1080 (9th Cir. 2007).

      The “collective knowledge” doctrine should have been applied in this case.

This doctrine “allows courts to impute police officers’ collective knowledge to the

officer conducting a stop, search, or arrest.” See United States v. Villasenor, 608


                                           2
F.3d 467, 475 (9th Cir. 2010). Where one officer knows facts constituting

reasonable suspicion, “and he communicates an appropriate order or request,

another officer may conduct a warrantless stop” without having been told the facts

justifying the suspicion. See United States v. Ramirez, 473 F.3d 1026, 1036-37

(9th Cir. 2007). Because the DEA communicated with the Oregon troopers, the

doctrine applies to “aggregate the facts known to each of the officers involved,”

regardless of whether the information giving rise to probable cause was actually

communicated to the troopers. Id. at 1032; see also United States v. Sutton, 794

F.2d 1415, 1426 (9th Cir. 1986).

      Applying the collective knowledge doctrine, the DEA and troopers had

knowledge that: (1) in a previous investigation, an informant had reported that his

“boss,” later identified as Ramirez, drove a tan Chevy Tahoe that had a secret

compartment in its seat for drugs; (2) Ramirez met with an informant before and

after a drug transaction with an undercover officer; (3) Ramirez was seen driving

to the same spot as another cocaine distributor (and informant) drove to meet his

supplier; (4) Ramirez and his co-defendant drove the Tahoe from Washington to

California, met briefly with a man at a hotel, and were seen leaving the hotel with

packages in hand traveling back to Washington; and (5) the troopers were faced

with an “overwhelming scent of air freshener” emanating from the Tahoe. These


                                          3
facts, taken together, easily establish reasonable suspicion to prolong Ramirez’s

detention for further investigation.

      Accordingly, we AFFIRM.
