A young Tuolumne woman died Thursday after being ejected from her white 1991 Chevrolet 1500 pickup which rolled down a steep embankment off Highway 108 near Hess Avenue in East Sonora.

The Tuolumne County Coroner’s Office on Friday afternoon identified the woman as 21-year-old Sabrina Thomas.

Sonora-area California Highway Patrol Public Information Officer Faustino Pulido said it was unknown how the solo-vehicle crash occurred.

“It would just be speculation at this time,” Pulido said.

The CHP suspects alcohol may have been a factor in the collision, but Pulido said he could not disclose why.

“We will not know until we get the toxicology back from the coroner,” he said.

The accident occurred about 8:30 p.m.

A CHP press release said Thomas was driving westbound on Highway 108, between Peaceful Oak Road and Hess Avenue. For an unknown reason, the vehicle crossed over the double-yellow center line and across the eastbound lane while traveling on a downhill grade. The vehicle drove off the south side of Highway 108 and down an embankment, which Pulido described as “very steep.”

According to Tuolumne County Sheriff’s Office logs, a caller at 8:31 p.m. said a vehicle “went airborne” near Peaceful Oak Road on Highway 108. The caller said they were searching for victims, but could not find any.

The caller said the vehicle was on fire and 100 feet over the embankment.

Pulido said he did not know the slope of the vehicle or how far from the road it came to rest. He said the vehicle rolled over multiple times while traveling down the embankment.

Thomas was not wearing a seatbelt and was ejected from the vehicle. She was pronounced dead at the scene by medical personnel.

Pulido said the crash remains under investigation, but it is not believed at this time other vehicles were involved in the collision.
