HOUSTON (AP) - A school bus has rolled off a freeway overpass in Houston, killing two students and seriously injuring two others and the driver.
Houston Independent School District released a statement saying a female student died at the scene Tuesday, while another girl died at a hospital.
Houston police spokesman Victor Senties said a car may have hit the bus after swerving to avoid another vehicle, causing the bus driver to overcorrect and go over the overpass.
"I live right next to the freeway and I was walking my kids to school and I saw it was a school bus. It's real bad," a witness said.
The woman who was driving the car was detained, but no charges have been filed. Senties said the investigation is ongoing.
Names and ages of the victims weren't immediately released. The district said the bus driver and two other students are seriously hurt.
The bus was bound for Furr High School, which also operates a charter school. According to the school, the driver has a clean driving record and the bus had a maintenance inspection in June.
Houston operates the largest public school district in Texas with about 215,000 students.
