SACRAMENTO, Calif. — One man is dead after his car veered a Highway 99 off-ramp Sunday night in Natomas, according to California Highway Patrol.

The 67-year-old man from Olivehurst was traveling westbound on Elkhorn Boulevard around 8 p.m. west of Highway 99 when his car diverted to the right and drove into a grassy area.

Officers arrived on the scene and found the driver unresponsive. The Sacramento Metro Fire Department performed CPR on the man, but could not resuscitate him. He was pronounced dead on the scene. 

CHP spokesperson Mike Zerfas said the man was the only passenger in the car. Although no other vehicles were involved in the collision, Zerfas said it was clear that the driver hit something.

"The side-impact airbags went off," Zerfas said. "He hit something hard enough to cause some sort of impact but not substantial damage to the car."

The cause of the crash is under investigation. It's unknown whether the driver was under the influence of drugs or alcohol. The Sacramento County Coroner's Office will release the name and cause of death of the driver. 

The North Sacramento Area CHP officer asks anyone with information call (916) 348-2300.
