Deputy Sheriff Ryan Clinkunbroomer was shot and killed in an unprovoked ambush at the intersection of Sierra Highway and Avenue Q just outside of the Palmdale Sheriff's Station at about 6:00 pm.

Deputy Clinkunbroomer was stopped at a red light when another car pulled alongside his patrol and an occupant opened fire, striking him in the head. A passerby located Deputy Clinkunbroomer in the vehicle moments later and alerted authorities. Deputy Clinkunbroomer was transported to Antelope Valley Medical Center where he succumbed to his wounds.

A suspect was arrested later in the evening.

Deputy Clinkunbroomer had served with the Los Angeles County Sheriff's Department for eight years and was a third-generation member of the agency. He is survived by his fiancée, parents and grandparents.
