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.

A grenade has not been found and remains missing after last week's explosion that killed three L.A. County sheriff's detectives, the sheriff says.

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