The Solano County coroner's office has released the names of the two teens who were killed in a solo vehicle crash near Vacaville on Saturday afternoon.

Five teens were ejected from the 1997 Chevrolet pickup truck that rolled several times in a field off of the east side of Pleasants Valley Road in unincorporated Solano County east of Vacaville, according to the California Highway Patrol.

The teens were returning from Lake Berryessa in Napa County around 5:20 p.m. in the full-size, four-door, lifted pickup, CHP officials said.

Witnesses said the truck was speeding south on Pleasants Valley Road south of Chester Way when the driver lost control on a curve in the road and the vehicle overturned several times in the field, according to the CHP.

The CHP said alcohol is suspected as a contributing factor in the cause of the crash.

The coroner's office identified the deceased as 19-year-old Gilberto Guzman, the driver of the truck, and 16-year-old Christie Brinsley, 16, of Vacaville.

Guzman suffered major head trauma and was pronounced dead at the scene, CHP officials said.

Brinsley was taken by ambulance to Kaiser Permanente Vacaville Medical Center. She suffered multiple major injuries and died during emergency surgery at 10:16 p.m. Saturday, according to the CHP.

The three other passengers in the truck were also hospitalized following the crash.

A 16-year-old Vacaville boy suffered major head and internal injuries and was taken by Calstar air ambulance to the UC Davis Medical Canter in Sacramento.

A 17-year-old Vacaville girl suffered fractures to her spine, right arm and left ankle and major abrasions and was taken by ambulance to Kaiser Permanente Vacaville Medical Center.

An 18-year-old Vacaville woman suffered a fractured spine, ruptured spleen and collapsed lung and was taken by a CHP H-30 helicopter to NorthBay Medical Center in Fairfield.
