According to prosecutors, Jaggar Smith admitted to drinking a whole bottle of MD 20/20, a fortified wine, the night he crashed, killing 16-year-old Salma Gomez and 16-year-old Chloe Robison, who were his passengers.
Smith was also allegedly speeding when he slammed into a tree, splitting his vehicle in half.
He's charged with two counts of intoxication manslaughter.

On Thursday, a judge ruled that he can't leave his house between the hours of 9 p.m. - 6 a.m. That curfew may change once school starts.
He will have an in-home breathalyzer and he's not allowed to drive.
His next hearing is set for Sept. 27.
Smith's attorney released a statement on behalf of him and his family:
Jaggar and his family cannot adequately express the depths of their despair over the loss of two of the most beautiful lives imaginable. We will have no further public comment as no words could ever fill the hearts of the families and friends of Chloe and Salma.
Investigators with the Texas Alcoholic Beverage Commission Enforcement Division are now trying to trace where he got the alcohol.
Smith's family describes him as a good kid.
Smith is a current Kingwood High School student heading into his junior year, but previously attended Atascocita High School. He also played football.
His aunt tells us he's never been in trouble.
Gomez and Robison were students at Atascocita High School.
Their friends went by the scene Wednesday morning to drop off flowers.
"They were good girls. They were fun, always good spirits, bright, always trying to have fun and laugh," said Graydon Morrow, a friend of the victims.
Humble ISD said grief counselors will be available at Atascocita High School on Thursday from 10 a.m. to 4 p.m.
