VISTA, Calif. — A deputy who shot a man at a North County church on Sunday has been identified by authorities.

The incident occurred shortly before 12:30 p.m. on the 1400 block of Calle Jules in Vista after the suspect was reportedly at the location holding a handgun to his head.

A single shot was fired by Deputy Justin Williams after the individual refused to drop his weapon, according to the San Diego Police Department.

Authorities say the suspect was struck in the legs and deputies immediately rendered first aid to the individual who was later taken to a local hospital with non-life-threatening injuries.

The San Diego Police Homicide Unit was called to the scene to conduct the shooting involving a deputy investigation. Detectives are currently gathering evidence, interviewing witnesses and examining the circumstances surrounding the shooting, SDPD said.

When the Homicide Unit completes its investigation, it will be reviewed by the San Diego County District Attorney’s Office.
