The second victim in a fatal crash that occurred Monday west of the Yolo County community of Rumsey has been identified by the Yolo County Coroner's Office as Marco Barajas, 14, of Redwood City.
Also killed was Ann Marie Miller, 39, of Redwood City.
The California HIghway Patrol reported that the driver of the vehicle, Reyes Barajas, 46, of Redwood City was arrested on suspicion of drunken driving after the crash.
Reyes Barajas was driving on State Route 16 east of County Road 40 about 4:45 p.m. Monday when his pickup went off the roadway, traveled down a steep embankment and hit a tree.
Miller, who was a passenger in the front seat, and Marco Barajas, who was in the back seat, were pronounced dead at the scene.
Robert LaBrash, Yolo County chief deputy coroner, said that Miller, who was wearing a seat belt, died of a neck fracture.
He said Marco Barajas died of a blunt-force chest injury. It is not known whether the boy was wearing a seat belt.
At the scene, Barajas was suspected to have been driving while intoxicated, according to the CHP. He survived with moderate injuries and was taken to Santa Rosa Memorial Hospital by helicopter.
Officers from the Santa Rosa office responded to the hospital and determined that Barajas was driving under the influence at the time of the crash. He was placed under arrest for two counts of felony DUI, causing death.
Barajas could face additional counts of manslaughter, according to the CHP.
