Obdulia Sanchez, who livestreamed the crash that killed her sister and injured another person, was sentenced to more than six years and four months in prison Thursday, officials said. The California teen, last month, pleaded guilty to gross vehicular manslaughter, driving under the influence and child endangerment in connection with the July 2017 crash.

“I feel like such an idiot,” Obdulia said expressing remorse for the crash, according to the Merced Sun-Star. “Why did God choose me to be the older sister? I can’t even do my job right.”

Merced County Deputy District Attorney Thomas Min, who was seeking the maximum 12-year sentence, revealed Obdulia was not only under the influence of alcohol but also had marijuana and cocaine in her system at the time of the crash.

Obdulia was arrested in July after she livestreamed the video of the crash on Instagram, which showed her beside her sister Jacqueline Sanchez. The incident took place when Obdulia was traveling with Jacqueline and her sister's girlfriend Manuela Seja. In the footage that surfaced on social media, Sanchez can be seen filming herself while driving and singing along to music as her 14-year-old sister and her friend sat in the backseat.

The alarming video showed Obdulia losing control of her vehicle and crashing.

“Wake up, baby,” she can be heard saying. “I’m f------ sorry, baby, I did not mean to kill you sweetie. This is the last thing I wanted to happen, okay? Rest in peace, sweetie.”

Obdulia told CBS affiliate KGPE from jail in August that the July incident wasn't the the first time she had livestreamed while driving.

"I didn't even know I looked like a monster — like I look like a freaking horrible monster. That was not my intention at all," Obdulia said at the time. 

The other passenger who was injured in the crash told reporters after the crash that she was attempting to flag down help while Obdulia continued to livestream the disturbing video. However, in August, Obdulia said she kept streaming as she called the police in an effort to attract help from the public to help pay for Jacqueline's funeral expenses.

"I made that video because I knew I had more than 5,000 followers," she wrote in a letter. "It was the only way my sister would get a decent burial. I would never expose my sister like that. I anticipated the public donating money because my family isn't rich."
