Missing Grenade Triggers Ongoing Search After LA Deputy Training Explosion Kills Three

A grenade remains missing following an explosion at the Los Angeles County sheriff’s training facility that killed three veteran deputies on the arson and explosives team. The two grenades were recovered from a Santa Monica storage unit and brought to the training center, where one detonated on July 18, causing the deadly blast, while the other has yet to be found despite thorough searches of the area and related locations. The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) has taken full control of the investigation into both the explosion and the missing grenade. Sheriff Robert Luna announced plans for an independent after-action review of the department's policies and procedures related to explosive handling to prevent future tragedies. Authorities urge the public not to touch any grenade-like objects and to immediately call 911 if such devices are encountered. The incident marks the deadliest event for the department in over 150 years, highlighting critical safety concerns around the handling and storage of explosives.
