An 18-year-old woman has been arrested in California on suspicion of killing her sister in a car crash that was streamed live on Instagram.

Obdulia Sanchez was allegedly filming herself singing to music behind the wheel when she lost control - causing the car to swerve across lanes, smash through a wire fence and overturn in a field.

Soon afterwards, the video appeared to show her tending to her 14-year-old sister, Jacqueline Sanchez Estrada, who died from her injuries.

In the graphic footage, which remained on Instagram for hours, she is heard saying: "Jacqueline… please wake up. I f****** killed my sister, OK? I know I'm going to jail for life."

Another 14-year-old girl was badly injured in the collision, which happened about 120 miles southeast of San Francisco.


Sanchez has been charged with gross vehicular manslaughter while intoxicated, as well as causing injury while under the influence of alcohol or drugs.

Records show she is being held on a $300,000 (£230,000) bond following Friday's crash.

The California Highway Patrol has said it is examining the Instagram video as part of its investigation.

According to her family, Jacqueline was preparing for her Quinceanera, a Hispanic tradition which celebrates a girl's 15th birthday.
