752 F.3d 1222
9th Cir.2014Background
- Rangel-Guzman arrested with 91.4 kilograms of marijuana found in his car at Otay Mesa after a CBP search following a dog alert.
- He and a companion claimed he borrowed the car; only Rangel-Guzman faced importation charges under 21 U.S.C. §§ 952, 960.
- Rangel-Guzman presented a convoluted trial defense, alleging different pre-arrest meetings and travel to Tecate, Ensenada, and back to the U.S.
- During cross-examination, the AUSA used questions implying prior inconsistent statements by Rangel-Guzman, prompting later appellate contention of improper vouching/advocate-witness conduct.
- Conviction affirmed for trial conduct, but sentencing remanded due to inadequately explained safety-valve denial; the two-level safety-valve reduction was not properly addressed.
