Rosario Zamora Rojo, a 41-year-old resident of Sacramento, was sentenced to nine years in prison for conspiracy to distribute and possess with intent to distribute fentanyl, cocaine, and methamphetamine. The sentencing was announced by Acting U.S. Attorney Kimberly A. Sanchez and took place on Thursday before U.S. District Judge Dale A. Drozd.
Court documents reveal that Zamora Rojo was a supplier for a drug trafficking organization responsible for importing counterfeit oxycodone pills laced with fentanyl from Mexico into northern California between May 2019 and January 2021. In November 2020, he supplied a pound of methamphetamine to co-defendant Jose Lopez-Zamora, which law enforcement later seized from one of the organization’s distributors. After this transaction, Zamora Rojo relocated to Mexico.
In December 2020, he provided thousands of fentanyl-laced M-30 pills and allowed access to his storage unit in Sacramento where these drugs were stored. Law enforcement subsequently searched the unit and confiscated over 13,000 fentanyl M-30 pills along with methamphetamine, heroin, and six firearms.
Fourteen co-defendants have pleaded guilty; ten have been sentenced to prison terms ranging from 19 months to 27 years. Sentencing dates are set for Jose Aguilar Saucedo on July 28, Luis Lopez Zamora and Sandro Escobedo in August, Leonardo Flores Beltran in October, and Erika Gabriela Zamora Rojo in December.
The investigation involved multiple agencies including the Drug Enforcement Administration (DEA), Homeland Security Investigations (HSI), Federal Bureau of Investigation (FBI), Bureau of Alcohol Tobacco Firearms and Explosives (ATF), among others. The Justice Department’s Office of International Affairs collaborated with Mexican authorities for the extradition of Luis Lopez Zamora.
This case is part of an Organized Crime Drug Enforcement Task Forces (OCDETF) operation aiming at dismantling high-level criminal organizations threatening the United States through coordinated multi-agency efforts.
