MEMORANDUM ***

Defendant-Appellant Jose Luis Murillo Espinosa was found guilty by a jury of 1) conspiracy to possess heroin and morphine with intent to distribute and, 2) possession of heroin or morphine with intent to dis *792 tribute, in violation of 21 U.S.C. §§ 841 and 846. He now appeals his convictions.

The district court did not plainly err when it allowed a Drug Enforcement Agency (DEA) agent to provide expert testimony about the structure and methods of drug-trafficking organizations, because the testimony was relevant and more probative than prejudicial. See United States v. Sepulveda-Barraza, 645 F.3d 1066, 1071 (9th Cir. 2011), as amended. The DEA agent’s expert testimony was directly relevant to the charge of conspiracy and rebutted Espinosa’s assertion that, although he was discovered in a drug stash house with heroin in his suitcase, he had nothing to do with the drug-distribution activities that occurred there. Further, the DEA agent’s testimony helped the jury understand Es-pinosa’s role in the conspiracy, including comments made by Espinosa to other co-conspirators, and the significance of evidence found in Espinosa’s room. In any event, Espinosa has not shown that admission of the testimony affected the fairness of the proceedings against him. See United States v. Rizk, 660 F.3d 1125, 1132 (9th Cir. 2011).

AFFIRMED.
