The girl is identified as 17-year-old Briana Tucci of Encino. Coroner's investigators say Tucci died as a result of injuries sustained in the rollover accident.
Tucci was killed when the Jeep she was riding in rolled over near Cuesta College. She was partially ejected when the driver 19-year-old Sanam Azernoon of Calabasas was traveling southbound on Highway 1 near Education Drive.
Azernoon drove her vehicle off the roadway into an embankment. The car then overturned several times. Several other people in the car were injured, some seriously.
None of the passengers in the back of the car were wearing seat belts. The CHP says they don't suspect alcohol played a role in the accident, but are still investigating.
