According to court records, Hernandez told police he was drinking at a bar with his cousin before the crash.
A fake Texas identification card, along with a bar receipt, were discovered in Hernandez's car after the crash, documents say.
Court records also show that Hernandez admitted to officers that he drank four or five beers and that he had been drinking since 6 p.m. Sunday.

He couldn't recall when he had his last drink.
Documents say that Hernandez had slurred speech, bloodshot eyes and poor balance immediately after the crash.
The Harris County District Attorney's Taskforce is investigating whether the bar overserved him. More charges will be filed if prosecutors can determine who was serving him.
Hernandez is expected in court Monday afternoon.
