MERCED, Calif. -- An 18-year-old woman has been arrested in California on suspicion of causing a deadly crash that was recorded live on Instagram.

Obdulia Sanchez was booked into the Merced County Jail on suspicion of DUI and vehicular manslaughter after Friday's crash that killed her 14-year-old sister and badly injured another 14-year-old girl.

CBS San Francisco station KPIX-TV reports that the girl who died appears to have been ejected from the car.

The California Highway Patrol said Sanchez was driving the car when it veered onto the right shoulder of a road about 120 miles southeast of San Francisco. She over-corrected, causing the vehicle to swerve across lanes, crash through a wire fence and overturn into a field.

The CHP is examining the video as part of the investigation.
