Following an investigation, the CASE (Contra Costa County Anti-Violence Support Effort) team last month served a search warrant on a home in Crockett.
Inside the residence, CASE team members located numerous weapons, including an assault rifle and a .30 caliber machine gun. The investigation is ongoing.
The CASE Team is a joint effort by the Office of the Sheriff, California Department of Justice, California Highway Patrol, Pittsburg Police Department and Walnut Creek Police Department. CASE was created in November 2011 as a collaborative effort to reduce violent crimes in Contra Costa, especially those related to illegal firearms.
