FRESNO — Prosecutors charged a teenage driver Wednesday with vehicular manslaughter while intoxicated and other counts after she lost control of her car while livestreaming on Instagram and recorded a crash that killed her younger sister.
The behavior of 18-year-old Obdulia Sanchez captured by the video was “disturbing and shocking,” Merced County Chief Deputy District Attorney Harold Nutt said in a statement.

He did not elaborate, but the footage shows she was dancing to music while she drove and taking her hands from the steering wheel.
Prosecutors say the video will be a key piece of evidence in the case.
Sanchez was driving the car on Friday when it veered onto the shoulder of a road about 75 miles (120.7 kilometers) northwest of Fresno, authorities said.
She overcorrected, causing the vehicle to swerve and overturn into a field, ejecting and killing her 14-year-old sister, Jacqueline Sanchez, authorities said.
