The Sonoma County Sheriff’s Department’s independent watchdog no longer needs to wait for internal investigations to wrap up to start investigating deadly deputy-involved shootings. That’s because of a new agreement, announced Wednesday. The Independent Office of Law Enforcement Review and Outreach is wasting no time taking advantage of the change. It has already started investigating a deadly deputy-involved shooting that happened last July, when a migrant worker was shot next to a creek bed in remote Knights Valley. The man’s family has filed a federal lawsuit against the Sonoma County Sheriff’s Office, claiming wrongful death and excessive use of force.
