Authorities say a 19-year-old driver who plowed into a minivan, killing a family of four, did not have alcohol in his system at the time of the crash.
California Highway Patrol officials also said Thursday they had found no evidence that Steven Culbertson had been at a bar prior to the Nov. 29 crash, despite initial reports he had been seen at one.
Authorities say the teen was going 70 mph to 90 mph when his car ran a red light and hit the minivan carrying Johnathan and Susan Maloney and their two young children.
They say there was no indication Culbertson had tried to brake. He later died at the hospital.
