Eight people were also injured in the crash.
Surveillance video shows a Mercedes-Benz barreling down La Brea at a high speed as dozens of cars cross the intersection on Slauson. The Mercedes runs a red light and slams into cars in the intersection, then bursts into flames and hurtles into a light pole, where it comes to rest.
After the crash, a streak of fire burned on the ground.
Smoke could be seen billowing from miles away.
Officer Franco Pepi, a California Highway Patrol spokesperson, had said Thursday afternoon that three adults, including a pregnant woman, and an infant were killed in the crash.
Authorities later found another person’s remains inside one of the burned vehicles, he said. That person’s gender or age were not known Thursday night.
Authorities took eight people to Ronald Reagan UCLA Medical Center for treatment, he said. Of those injured, six were teens and one suffered major injuries.
A woman who did not want to be named told the Times a Mercedes-Benz hit her car as she was leaving a United Oil gas station.
“I was getting out, had got gas,” she said. “All of a sudden that Mercedes is coming at me on ... fire. I didn’t have any time to think about it. It hit my car. I veered, hit the bench on the side.”
The crash caused her to fear a gasoline-fueled explosion, she told the Times.
