TEXAS — Concrete truck driver, 42-year-old Jerry Hernandez, has been charged with criminally negligent homicide, records show, in the rollover school bus crash that killed two in Bastrop County on March 21.

The Austin American-Statesman has revealed that the driver of the concrete truck involved in the Bastrop County collision with a school bus carrying pre-K students last Friday admitted to consuming cocaine earlier that morning and smoking marijuana the night before.

The charges come about a week after a school bus carrying Tom Green Elementary pre-K students who were returning from a field trip to the Bastrop Zoo. Forty-four students and 11 adults were on the bus. The crash resulted in the deaths of a 5-year-old boy named Ulises Rodriguez Montoya and a 33-year-old man named Ryan Wallace.

The concrete truck veered across the double yellow line and forced the school bus to swerve, resulting in the bus skidding and rolling over before finally stopping upright.

Court documents reveal Hernandez faced charges of driving without a license in 2006.
