The Santa Rosa Police Department’s Gang Crimes Team executed a search warrant in Rohnert Park on Tuesday, leading to a major arrest in an illegal firearms operation.
Detectives searched an apartment on Commerce Boulevard and found a 3D printer along with several 3D-printed firearm parts, including pistol frames and AR-15 receivers, often used to create untraceable “ghost guns.”
The resident, 18-year-old Mario Reynosa, was detained and arrested on charges of unlawful firearms possession.
