Authorities early Tuesday were searching for the driver of a van that crashed off Guerneville Road west of Santa Rosa, killing one man and injuring three others, the CHP reported.
The men were heading to work at an Occidental vineyard when the driver drove off the road just west of Olivet Road and struck a pine tree at about 5:10 a.m., CHP Officer Terry Munoz said.
The Chevrolet Astro Van knocked over the 21-foot tree and flipped, ejecting a passenger, landing on its side and on top of the man, Munoz said.
The man was pronounced dead at the scene, CHP officials said.
Paramedics transported 34-year-old Domingo Layata-Mendez and 26-year-old Nahum Avendano, both of Santa Rosa, to Santa Rosa Memorial Hospital, CHP Officer Jon Sloat said. A Piner High School student, Ignacio Hernandez-Rubio, 17, was taken to Kaiser Hospital, he said.
The men's injuries included head trauma and broken bones, Munoz said.
Authorities were still trying to determine the identity of the driver, who the other men told officers they called "Tio," which means uncle in Spanish, Munoz said.
The men were employees of Mid Valley Labor Services, a labor contractor based in Madera, Sloat said.
Witnesses to the crash told officers that they saw a man run into a nearby vineyard after the crash.
Before he ran, he left a dark hooded sweatshirt on a nearby tree, Munoz said.
Tire tracks showed that the car traveled about 350 feet from where it veered off the road onto a gravel shoulder, jumped a driveway and continued until it struck the tree. The van's hood was crushed in the impact.
