Rohnert Park Man Suspected Of Supplying AR-Style Guns To Street Gang Indicted

ROHNERT PARK, CA — A Rohnert Park man was charged with unlicensed firearm manufacturing and trafficking after allegedly supplying more than 20 AR-style rifles and ammunition to a Santa Rosa street gang, federal prosecutors said Monday.

Jose Alfredo Perez, 41, was arrested on Friday following his federal indictment on multiple firearms-related charges, and made his initial court appearance later that day, according to an announcement by the U.S. Attorney’s Office for the Northern District of California.

Authorities said they also suspect Perez of circumventing federal and state laws to deliver untraceable weapons to convicted felons, prompting the Homeland Security Task Force to launch a multi-agency investigation.

U.S. Attorney Craig H. Missakian and FBI Special Agent Sanjay Virmani announced the charges, emphasizing that Perez is presumed innocent until proven guilty.

Prosecutors suspect Perez manufactured and supplied ArmaLite-style rifles and ammunition to members of the Angelino Heights Sureño street gang in Santa Rosa, who could not legally possess firearms due to prior convictions.

Investigators said they believe Perez arranged for firearms parts, which could not legally be shipped to California, to be sent to an out-of-state address provided by a suspected gang member. Investigators suspect that parts were then transported to Perez, who used them to assemble untraceable, unserialized guns.

In January 2025, officers seized 11 unserialized assault weapons they suspect Perez manufactured. Later, in April 2025, authorities searched Perez’s residence and discovered what they considered a makeshift workshop in his shed and garage, stocked with firearm kits, tools, and machinery for building rifles.

Authorities are holding Perez in federal custody as he awaits his arraignment and detention hearing scheduled Wednesday before U.S. Magistrate Judge Sallie Kim.

If convicted, Perez faces up to five years in prison and fines for unlicensed firearm manufacturing, and up to 15 years per count for firearms trafficking.

The case was investigated by the Homeland Security Task Force’s Core Region 2, a collaboration including the FBI, California Highway Patrol, and Santa Rosa Police, and is being prosecuted by the U.S. Attorney’s Office. Assistant U.S. Attorney Jared Buszin is leading the prosecution, according to the press release.
