MEMORANDUM *

Ricardo Antonio Alearaz-Chavez appeals his 48-month sentence for importation of 11 kilograms of cocaine. He seeks relief in the form of a mitigating role downward adjustment under U.S.S.G. § 3B1.2. Viewing the totality of the circumstances, we conclude that the district court did not clearly err when it denied Alcaraz-Chavez’s request for the adjustment. U.S. Sentencing Guidelines Manual § 3B1.2, Commentary Application Note 3(c). The district court was not in a position to speculate on the role played by other, unknown, participants and it was clear that the defendant knowingly transported a large amount of contraband across the border. United States v. Lui, 941 F.2d 844, 849 (9th Cir. 1991).

AFFIRMED
