One person died Wednesday night in a crash in Concord that involved at least one law enforcement officer, authorities said.
The Contra Costa County Sheriff’s Office confirmed on Twitter around 11 p.m. that it was investigating “an officer-involved fatal incident” in the area of state Highway 242 and Highway 4. Two Concord police officers and a sheriff’s deputy at the scene confirmed to this news organization that “all deputies are all right.”

Sheriff’s office spokesman Jimmy Lee declined early Thursday morning to specify what led to the crash or how deputies or other law-enforcement officers may have been involved. Several officers and a California Department of Transportation worker at the scene indicated that it involved a deputy driving onto the westbound Highway 4 on-ramp from eastbound Highway 242.
The westbound Highway 4 on-ramp from Highway 242 was closed for several hours.
Video from after the crash showed a white Toyota Prius being towed away from the on-ramp. Crime-scene tape in the embankment underneath Highway 4 also extended to a fence adjacent to an apparent homeless encampment on Arnold Industrial Way.
