"We believe the individual ran off the roadway and succumbed to his injuries," said CHP spokesman officer Christopher Falkowski.
There are no witnesses to the accident, Falkowski added saying the victim was a young man, approximately 25 years of age, driving a 2005 GMC SUV sports utility vehicle.
Although his identification has not been established yet, CHP officers believe based on the vehicle's registration that the victim could possibly be from Capitola, Falkowski said.
The Santa Clara County Coroner's Office will have to ID the body, Falkowski said, adding that investigators won't know if alcohol or drugs were a factor in the crash until a toxicology report is completed by the coroner.
"We don't know what caused the collision," Falkowski said. "We don't know if it was speed, if he was swerving from not hitting a deer ... the primary collision factor is still under investigation."
