A former astronaut has been charged with murder after a car crash killed two girls in Alabama.
State police said 59-year-old James Halsell Jr, of Huntsville, was arrested after a crash that killed 11-year-old Niomi Deona James and 13-year-old Jayla Latrick Parler.
Officers said a car driven by Halsell collided with a Ford Fiesta in which the girls were passengers. Both victims were thrown from the vehicle and died. Two others were injured.
Police said a preliminary investigation indicates alcohol and speed may have been factors.
An online Nasa biography says Halsell went to work in the aerospace industry in 2006 after a career that included five space shuttle flights starting in July 1994.
