How the Equipment Was Found

On July 17, 2025, LASD’s arson and bomb team assisted local police in Santa Monica, responding to a report of two grenades discovered in a tenant’s underground parking storage locker. Deputies used an X-ray machine and believed the grenades to be inert, or safe, meaning they were not expected to explode The Press Democrat+4ABC7 Los Angeles+4WSOC TV+4.

Believing the devices non operational, they were moved to the Biscailuz Training Facility to be examined and disposed of. It was during handling the next morning that one detonated, killing the three detectives Reddit+15FOX 11 Los Angeles+15WBAL+15.

Victims: Experienced and Respected

All three were highly trained, trusted members of the department and had nearly 74 years of combined service People.com+1MySA+1.

What Went Wrong and What’s Still Unknown

While officials confirmed that only one grenade exploded, the other remains missing, posing an ongoing danger. LASD Sheriff Robert Luna said authorities have searched using X-rays, grid sweeps, and checks of every vehicle, building, locker, gym, and surrounding shrubbery in the facility—but the second grenade is still nowhere to be found ABC7 Los Angeles+6FOX 11 Los Angeles+6ABC7 Los Angeles+6.

ATF (Bureau of Alcohol, Tobacco, Firearms and Explosives) has taken over the investigation into the missing device. FBI and LASD homicide detectives are leading the broader probe, working to determine the cause of the explosion and whether criminal charges are warranted FOX 11 Los AngelesABC NewsWikipedia.

Measures Taken After the Blast

Sheriff Luna said this incident is the department’s worst single-day loss of life since 1857, when four officers were killed in the line of duty FOX 11 Los Angeles+11The Press Democrat+11WBAL+11.

He ordered an independent review of all policies and procedures related to ordnance handling. From now on, all devices—whether believed inert or not—will be treated as live until safely disposed of WSOC TV+3The Press Democrat+3Chron+3.

Looking Ahead: Investigation and Reporting
