SRPD Gang Crimes Team recovers two illegal firearms and makes an arrest during the service of a search warrant

On October 22, 2025, at approximately 4:00 p.m., detectives with the Santa Rosa Police Department Gang Crimes Team (SRPD GCT), served a search warrant at a residence in the 2100 block of Naomi Place. GCT detectives had been investigating the resident for suspected possession of illegal firearms.  

GCT detectives located two illegal firearms during the service of the search warrant; a short-barreled AR-15 style rifle, and a 9mm privately manufactured firearm (commonly referred to as a “ghost gun”). Ammunition for the 9mm handgun was also located.  

Detectives determined the firearms and ammunition belonged to Scott Cast, the 38-year-old resident of the home. Cast, a convicted felon, is prohibited from owning or possessing firearms or ammunition. 

Cast was home at the time of the search warrant and arrested. He was booked into Sonoma County Jail for the following offenses: 

33215 PC – Possession of a short-barreled rifle 

30605(a) PC – Possession of an assault weapon 

29800(a)(1) PC – Felon in possession of a firearm 

30305(a)(1) PC – Felon in possession of ammunition 
 

The SRPD Gang Crimes Team was reinstated in December 2023, after a long absence fueled by staffing shortages. This team of four plainclothes detectives and a sergeant work to investigate gang-related offenses in Santa Rosa. The GCT has four key priorities: prevention, intervention, education, and enforcement. In 2024, the GCT recovered 82 illegal or illegally possessed firearms; seized four 3D printers used in the manufacturing of firearms; and made 30 referrals to the Violence Prevention Partnership, an organization dedicated to empowering all youth to reach their full potential and find safe pathways out of a gang lifestyle. GCT efforts have contributed to a significant reduction in violent crime. In 2024, Santa Rosa saw a 71% decrease in homicides and experienced zero gang-related homicides, where in 2023, half of all homicides had a connection to gang violence.
