A teenage boy was killed, and his father and a male cousin were injured when a car apparently veered off Interstate 5 in Woodland early Thursday morning, the California Highway Patrol said.
The 13-year-old boy, whose identity has not been released by the Yolo County Coroner's Office, was pronounced dead at the scene.
The driver, Sergio Gomez-Sandav, 18, of Turlock, and a male passenger, Galvan Audel, 39, of Vancouver, Wash. suffered abrasions and were treated at the scene.
At 4:55 a.m., Gomez-Sandav was driving a 2013 Toyota Corolla, heading south on I-5, and going 65 mph. Just north of Country Road 22, the vehicle veered off of I-5, and rolled over several times as it fell down an embankment.
As it rolled, the 13-year-old boy, who was sitting in the left rear seat, was partially ejected, and fatally injured. The car landed on its wheels, facing northwest in a field.
Gomez-Sandav told investigators that he had fallen asleep, as he had been driving from Washington state.
Authorities said that Gomez-Sandav is a cousin of the boy, and that Audel is the boy's father.
At this time, alcohol and drugs are not considered factors in the accident, CHP said.
