An 18-year-old woman has been arrested after crashing her car and killing her 14-year-old sister, a moment she live streamed to her Instagram account.
Obdulia Sanchez, from Stockton, is accused of driving under the influence during the deadly incident in Los Banos, California on Friday.
Her younger sibling, Jacqueline Sanchez, died at the scene and authorities are now looking into the graphic video that they believe shows the deadly events unfolding.
The live Instagram footage shows Obdulia talking to the camera as she drives normally and the moment the car rolled over a barbed wire fence and onto a field. Gory visuals from the scene then show Jacqueline's body strewn on the floor, the other girl in the car waving for help and Obdulia talking to the camera.
During the live recording Obdulia said: 'Jacqueline, please wake up. I f****** killed my sister, OK? I know I'm going to jail for life. I love my sister... this is the last thing I thought was going to happen to us.'
'I killed my sister, but I don't care. I killed my sister. I know I'm going to prison, but I don't care. I'm sorry baby. I'm a hold it down.'
The disturbing clip ends with her kneeling next to her dead sister and saying: 'Wake up baby, I'm f**king sorry baby, I did not mean to kill you sweetie.'
Merced County Sheriff Vern Warnke said Jacqueline was not wearing a seatbelt when the car crashed and rolled on Henry Miller Road at about 6.45pm on Friday.
The 14-year-old was thrown through the back window of the car, authorities said.
Another girl, who police have not named but confirmed she was a minor, was also not wearing a seatbelt and suffered major leg injuries in the crash.
Authorities say they were made aware of the shocking crash scene video circulating on social media and were working to determine if it was authentic.
Family members have confirmed the video was shot by Obdulia.
They say the victim, Jacqueline, was supposed to celebrate her Quinceanera (15th birthday) on Sunday.
Mary Hernandez, of Stockton, who viewed the live stream, decided to record it while unsure if the shocking footage was real.
'At first we didn't even want to believe it was real,' she said.
'I recorded it and posted it mainly because as someone who uses Snapchat I see a lot of people driving with their Snapchats doing what she was doing, so to me it was like an eye opener.'
