SACRAMENTO, Calif. - Jose Cruz Ivan Aispuro, 39, of Stockton, was sentenced Tuesday by U.S. District Judge John A. Mendez to 10 years in prison and ordered to forfeit $42,066 to the United States for conspiracy to distribute heroin and fentanyl and the distribution of fentanyl, U.S. Attorney Phillip A. Talbert announced.

According to court documents, between November 2018 and December 2019, Aispuro and co-defendant Frank Guzman, of Stockton, conspired to distribute and possess with intent to distribute at least 1 kilogram of heroin and at least 400 grams of counterfeit pharmaceutical pills containing fentanyl. As part of this conspiracy, Aispuro supplied heroin that Guzman sold to an undercover agent and another person on three occasions and supplied 500 counterfeit oxycodone pills containing fentanyl that Guzman also sold to the undercover agent. Approximately 4.5 kilograms of heroin and $42,066 in cash were seized from Aispuro's residence. Approximately 10,000 counterfeit oxycodone pills containing fentanyl and 2.8 kilograms of heroin were seized from Guzman's residence.

This case was the product of an investigation by the Drug Enforcement Administration with assistance from the U.S. Marshals Service and the San Joaquin Metropolitan Drug Task Force. Assistant U.S. Attorney David W. Spencer prosecuted the case.

Guzman also pleaded guilty to conspiracy to distribute heroin and fentanyl and was sentenced to 10 years in prison by Judge Mendez on Dec. 12, 2023.
