SAN DIEGO – A woman was killed and two children were injured Friday when she lost control of the vehicle and overturned down an embankment, California Highway Patrol reported.

About 8:30 a.m., the 35-year-old woman was traveling in a Chevrolet Tahoe westbound on Interstate 8, west of Tavern Road, in Alpine with two kids, ages 3 and 9, CHP Officer Travis Garrow said in a news release. For reasons unknown, the woman lost control of the SUV, traveling off the road onto the dirt portion that separates the westbound and eastbound lanes of I-8.

Her SUV overturned down the dirt embankment and landed in the No. 1 eastbound lane, Garrow said, throwing off debris that hit an eastbound Mazda driven by a 44-year-old El Cajon woman.

The result ejected the SUV driver, who wasn’t wearing a seatbelt, investigators say. She died at the scene.

Both children were wearing seatbelts in the backseat of the SUV and suffered moderate injuries, according to Garrow. They were taken by ambulance to Rady Children’s Hospital for treatment.

The San Diego County Medical Examiner’s Office responded to the deadly crash scene and took possession of the decedent. The agency plans to release her name after her family has been notified.

Few other details were made available, but investigators say drugs and alcohol don’t appear to be a factor.
