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.

A grenade is missing from the scene of a deadly explosion at a Los Angeles County Sheriff's Department training facility, authorities announced.
