The woman who was killed after her SUV ended up in the Kern River was possibly under the influence of alcohol.

The California Highway Patrol on Tuesday morning reported a 35-year-old Bakersfield woman was also not wearing her seat belt prior to the deadly crash on Sunday.

The CHP says the woman was driving at a high rate of speed on Round Mountain Road in the area of China Grade Loop when the SUV went off the road at a curve.

The SUV hit an oil pump and a fence and eventually went airborne off a hillside, falling about 40-50 feet. The SUV rolled multiple times before coming to a rest, submerged upside down in the Kern River.

The vehicle was found the next day by oil field workers.

The woman was pronounced dead at the scene.
