The Ford F-150 the two were in went off the road and rolled several times. The 12-year-old was pronounced dead at the scene and her grandmother was transported to Ben Taub Hospital, where she later died.
The witness describes the car that ran them off the road as a dark-colored sedan, possibly with four doors. Police say it's possible that driver didn't realize there had been contact between the two vehicles.
Pasadena police ask anyone who may have witnessed the accident or who may have information in this case call 713-477-1221.
