The Contra Costa County Office of the Sheriff, Contra Costa District Attorney’s Office, and the Oakley Police Department continue to investigate the Discovery Bay officer-involved shooting per the county law enforcement involved fatal incident protocol.

Last night, March 22, 2022, at about 8:44 PM, deputy sheriffs were dispatched to a domestic disturbance at a residence on the 8000 block of Westport Circle in Discovery Bay. After speaking to the caller, a deputy attempted to talk to a man in the residence. As deputies tried to speak to him through a screen door, the man took out a knife and raised it over his head. Deputies commanded him to drop the knife. The man then brandished what appeared to be a rifle at the deputies, who retreated to safe distance away from the residence to set up a perimeter.

A short while later, as other deputies and Oakley police officers arrived at the scene, the man came out of the residence with the weapon raised and pointed as he walked toward the deputies and officers on the street. They attempted to deescalate the situation by giving him numerous commands to put his weapon down. He refused to comply and advanced on the deputies and officers who discharged their firearms striking the man. They immediately requested an ambulance and the fire department to respond and began performing life-saving measures. The man was transported to a local hospital where he was later pronounced deceased. [continued below…]
