The accident happened just after 10 PM Wednesday. Gabriel Paredez, 23, was driving north on Gregg Street when his car went off the road and hit a traffic light pole. Paredez and his mother - 55 year-old Olga Hernandez - were taken to Scenic Mountain Medical Center with severe injuries. Hernandez died a short time later.
Big Spring Police say alcohol wasn't a factor in the crash and that both victims were wearing seat belts. They say Paredez might have had a seizure behind the wheel.
The investigation is ongoing.
