San Joaquin County Man Pleads Guilty to Federal Gun and Drug Charges

FRESNO, Calif. — Alphonso Jimenez, 31, of Stockton, pleaded guilty today to possession with intent to distribute methamphetamine, cocaine, heroin, and fentanyl and using a firearm during and in relation to a drug trafficking crime, U.S. Attorney Phillip A. Talbert announced.

According to court documents, in 2021, a team of local and federal law enforcement officers partnered in an investigation into the drug trafficking activities of Jimenez and co-defendant Erik D. Mendoza-Contreras, 33, of Stockton.

During the investigation and on multiple occasions, confidential sources working with law enforcement purchased several pounds of narcotics from Mendoza and Jimenez. On Feb. 23, 2022, Jimenez delivered 28 pounds of methamphetamine to Mendoza for further distribution to a customer. A subsequent search of Jimenez’s home recovered over 31 kilograms of methamphetamine, over 28 kilograms of cocaine, over 6 kilograms of heroin, over 350 grams of counterfeit M-30 pills containing fentanyl, approximately $297,000 in cash, and a firearm.

This case is the product of an investigation by the Drug Enforcement Administration and the San Joaquin County Metropolitan Narcotics Task Force. Assistant U.S. Attorney Antonio J. Pataca is prosecuting the case.

Charges are pending against Mendoza; he is presumed innocent until and unless proven guilty beyond a reasonable doubt.

Jimenez is scheduled to be sentenced by U.S. District Judge Jennifer L. Thurston on May 30, 2023. Jimenez faces a mandatory minimum sentence of 15 years up to life in prison. The actual sentence, however, will be determined at the discretion of the court after consideration of any applicable statutory factors and the Federal Sentencing Guidelines, which take into account a number of variables.
