Contra Costa County sheriff’s deputies were notified at 9:37 p.m. Monday that a possible accidental shooting had occurred in the 4200 block of Slifer Drive in the community of Discovery Bay.

A man was found at the scene suffering from a gunshot wound to the lower leg, according to the East Contra Costa Fire Protection District.
