Authorities say Obdulia Sanchez was driving drunk when she veered off the road and crashed. The teen was live on Instagram and recorded her 14-year-old sister's death.

Authorities say Obdulia Sanchez, from Stockton, California, was driving under the influence of alcohol around 6:40 p.m. when she lost control of the Buick and swerved across lanes, crashing through a barbed wire fence and overturning in a field, ejecting her sister, Jacqueline Sanchez, and another 14-year-old girl who sustained "major injuries," 

The two teen girls were sitting in the backseat and not wearing seat belts, according to the CHP report.

Before crashing, Sanchez had been recording herself singing along to music and flipping off the camera, capturing glimpses of the two younger teens in the back as she turned her phone from herself onto the empty road. 

"I think this video can get a lot of people to think twice about using their phones while driving now," Mary Hernandez who recorded a copy of video said.

She says the video got up to 700,000 views before Facebook took it down.
