Lauren Pozen reports from East Los Angeles, where the search for a missing grenade continued on Saturday night after an explosion last week that killed three Los Angeles County Sheriff's Department deputies.

Sheriff’s officials were warning the public Saturday to be on the lookout for a possibly live grenade — one of two that were found at a Santa Monica apartment building storage unit last week, after the other one detonated the following day in East Los Angeles, killing three sheriff’s detectives.

The explosion at the Biscailuz Training Facility in East Los Angeles killed three members of the agency's bomb squad.
