The crash was first reported just after 7 a.m. Thursday on Highway 20, about a mile west of Walker Ridge Road, according to the California Highway Patrol.
The CHP’s initial report said that a white van had gone into a ditch.
Over the course of the day, the CHP requested a response from the Multidisciplinary Accident Investigation Team, or MAIT, to assist, according to scene reports.
Officer Joel Skeen of the CHP’s Clear Lake Area office told Lake County News that they are still investigating.
“What we know is that it was a solo vehicle which was a white sprinter van traveling eastbound on State Route 20,” Skeen said.
“There was some suspicion that a second vehicle may have been involved which is why the MAIT team was called out,” Skeen explained. “As of now it appears the second vehicle was not involved but we will know more with some follow-up investigation.”
Skeen said a male occupant who was alone in the vehicle died.
The man will be identified pending next of kin notification, Skeen said.
