SACRAMENTO, Calif. — A federal grand jury returned a four-count indictment, which was unsealed Wednesday, charging Stockton residents Rosalva Angulo Castillo, 53, and Adan Garcia Castillo, 45, with conspiracy to traffic heroin and methamphetamine and with distributing heroin, U.S. Attorney Phillip A. Talbert announced.

According to court documents, from January 2018 through May 2023, Angulo Castillo and Garcia Castillo conspired to distribute and possess with intent to distribute heroin and methamphetamine. On Oct. 25, 2019, Garcia Castillo distributed at least one kilogram of heroin, and on Dec. 8, 2020, and July 13, 2021, Angulo Castillo distributed at least 100 grams of heroin.

This case is the product of an investigation by the Drug Enforcement Administration, with assistance from the Federal Bureau of Investigation, Homeland Security Investigations, the IRS Criminal Investigation, the California Highway Patrol, and the San Joaquin County Metropolitan Narcotics Task Force. Assistant U.S. Attorneys David W. Spencer and Emily G. Sauvageau are prosecuting the case.

If convicted, each defendant faces a minimum of 10 years of prison and a maximum statutory penalty of life in prison. Any sentence, however, would 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. The charges are only allegations; the defendants are presumed innocent until and unless proven guilty beyond a reasonable doubt.

The case was investigated under the Organized Crime Drug Enforcement Task Forces (OCDETF). OCDETF identifies, disrupts, and dismantles the highest-level criminal organizations that threaten the United States using a prosecutor-led, intelligence-driven, multi-agency approach.
