(Palmdale, CA) — The search continues for suspects in the deadly ambush shooting of a L.A. County Sheriff’s deputy in Palmdale. A candlelight vigil was held Sunday night for Deputy Ryan Clinkunbroomer, who was found with gunshot wounds in his patrol vehicle last Saturday evening. He was pronounced dead at an area hospital.

Sheriff’s officials say they don’t know if Deputy Clinkunbroomer was targeted or if he was just killed because he was a law enforcement officer but they are outraged at the killing.

No arrests have been made and authorities are hoping surveillance video in the area might help them identify suspects in the case.
