Austin-Travis County EMS said at around 2:50 p.m. that its medics were assisting with the rollover on West State Highway 21, near Caldwell Road and just southeast of Highway 130, in Bastrop County. That site is near the Mustang Ridge area. Hays CISD confirmed that a bus carrying Tom Green Elementary School pre-K students was involved in the crash. The students were returning from a field trip to the Bastrop Zoo. Forty-four students and 11 adults were on the bus.
Hays CISD said the parents of students on the bus have been notified by Tom Green Elementary, and the district is in the process of reunification.
