Three 18-year-olds were among the four people killed in a crash along the 110 Freeway interchange with the 91 Freeway in Gardena early Sunday, the California Highway Patrol reported.
The single-car crash, which involved a blue Ford Probe, was reported about 3:30 a.m. on the northbound side of the highway where it meets with the westbound 91, officials said.
The driver was apparently traveling at a high rate of speed when the vehicle crashed into a guardrail, went down an embankment and caught fire, according to the CHP.
The victims were initially trapped inside the car but were declared dead at the scene.
In a news release issued Sunday evening, the CHP said one of the victims was an 18-year-old female from Compton, an 18-year-old male driver from Inglewood and an 18-year-old male passenger. The age of the fourth victim, also a male, was not released.
A SigAlert was issued in the area about 3:40 a.m. and the interchange remained closed until 11:30 a.m., the CHP reported.
