Authorities said 23-year-old Taylor Phillips was driving an SUV with her mother and her 1-year-old son inside when Erick Hernandez crossed three lanes of traffic in his pickup truck and slammed into her head-on.
Hernandez appeared in court Wednesday on an intoxication manslaughter charge.
According to court records, Hernandez told police he was drinking at a bar with his cousin before the crash.
On Wednesday, prosecutors say a video from inside the South Houston bar shows Hernandez consuming 12 drinks, including three shots of tequila, before getting into his truck.
During the six hours Hernandez was inside the bar no one asked him for an ID, according to prosecutors.
Four bar workers were arrested Wednesday on charges of serving to a minor, and one employee is charged with possession of an unauthorized beverage retailer.
Prosecutors say three of the five employees arrested were also taking shots of tequila with Hernandez.
Court documents showed that the bar did not have a liquor license with the State of Texas. The bar was only permitted to sell beer and wine.
Investigators tell us the bar already has six TABC violations this year that include selling to minors.
The district attorney's office is also considering action to try to shut down the business.
