The San Mateo County Sheriff’s Office has announced four arrests and the seizure of over 30 firearms, as well as ammunition and other contraband, amid a multi-agency investigation into interstate weapons trafficking.
The investigation began in October 2021 — a joint effort between the San Mateo County Sheriff’s Office, the ATF (Bureau of Alcohol, Tobacco, Firearms, and Explosives), San Francisco PD, and the San Francisco DEA Metro Task Force — aimed at curbing the trafficking of firearms between Arizona and California, as well as the sales of illegal firearms throughout San Mateo County.
Agents went undercover and purchased firearms, including several “ghost guns,” high-capacity magazines, armor-piercing ammunition, and automatic weapons, the Sheriff’s Office said.
On January 20 of this year, agents served multiple search and arrest warrants throughout San Mateo County and one in the city of Oakland, ultimately seizing fifteen firearms of various types, a suppressor, automatic pistols with modified Glock switches, high-capacity magazines, and a 3D printer.
Investigators also arrested four people, two of whom were taken into federal custody. Their names have not been released.
