Authorities say 24-year-old Stephanie Soza of Selma was driving three passengers on Highway 180 east of Highway 245 around 4:30 a.m. Saturday morning.
According to a CHP report, Soza drove her car off the road and collided with a mile post marker before going down an embankment. The vehicle then struck several trees.
Investigators say two of the passengers, an 18-year-old man and a 21-year-old man, were killed in the crash. They say neither were wearing seatbelts.
The CHP says Soza left the vehicle and walked back to the road seeking help. After being treated at Community Regional Medical Center, Soza was booked into the Fresno County Jail on three counts of felony DUI resulting in injury and two counts of gross vehicular manslaughter while intoxicated.
