Lt. Corey Paulich said the woman who died was Mary Patricia Mahoney, 58.
Mahoney was driving a 1999 Toyota 4Runner westbound on Highway 20 near Walker Ridge Road at 8:15 p.m. Tuesday when she went off the right side of the road and onto the dirt shoulder.
She overcorrected and steered the Toyota to the left. The SUV overturned, went off the south side of the highway and Mahoney – who was not wearing a seat belt – was ejected as the vehicle went down a dirt embankment, according to the California Highway Patrol report.
The CHP said Mahoney died at the scene of her injuries.
Mahoney’s passenger, 20-year-old Isabella Rosario Moon of Chico, sustained minor to moderate injuries and was flown to Santa Rosa Memorial Hospital, the CHP said.
The crash remains under investigation.
