Ammunition exploded Friday inside a trailer parked at an Los Angeles County Sheriff's lot across from the station in Marina del Rey, prompting residents nearby to shelter in place.
Smoke was coming out of the trailer hours after the initial fire was put out and people living nearby were stunned and wondered why that ammunition was there in the first place.
"I had just gotten home and saw the fire in the trailer and the ammunition started exploding," a resident said. "It was really loud and it echoed."
"It sounded like a shootout. All I could do was duck and take cover."
It started with a fire around 6 p.m.
It took up to 20 minutes before the Fire Department moved in.
For more than 30 minutes, folks who live at the apartment complex next door were told to stay inside as the ammunition exploded over and over.
The trailer is a mobile shooting range for LA County Sheriff's deputies to keep up on their shooting qualifications, but some residents weren't aware of it.
Nobody was inside when the trailer caught fire, but the people who live nearby said they wish they would've known it was there.
"I've already let my apartment complex know that it was there and I that I was very unhappy about the situation," a man said. "We'll see what happens."
Nobody was hurt during the fire. Arson investigators were probing the cause.
