LOS ANGELES (AP) — A veteran Los Angeles County sheriff’s deputy has died six months after he was seriously hurt when a fire broke out inside a trailer serving as a mobile shooting range, his family said Sunday.

Alfredo “Freddy” Flores died from his injuries Saturday night, Joe A. Nunez, an attorney for the family, confirmed to KABC-TV.

Flores and another longtime deputy were critically injured on Oct. 10 when equipment malfunctioned inside the approximately 50-foot (15-meter) trailer at a training facility northwest of downtown Los Angeles.

Crews fought the flames for several hours and were challenged by live ammunition that was still inside the trailer.

The trailer had two “firing lanes” inside and one of the deputies was participating in firearms qualification, which the department requires deputies to do once a quarter, Sheriff Robert Luna said in October. The department hasn’t released the results of its investigation into the accident at a sprawling campus that also houses the Pitchess Detention Center, a county jail.
