TAVARES, Fla.?A drag racer who accidentally plowed into his mother’s car, killing her and an elderly passenger, has been charged with their deaths.

Dwight Samples, 21, faces up to 30 years in prison and a $20,000 fine if convicted on two counts of vehicular homicide in the Dec. 19 accident that killed his mother, Diane Samples, 45, and Vivian Green, 72.

The young man surrendered Tuesday and posted $10,000 bail. Prosecutors also issued a warrant for Jerrod Abbott, 24, who allegedly was drag racing with Samples and faces identical charges.

The two men were allegedly going nearly 120 mph on Dec. 19 on a small highway northwest of Orlando when Samples smashed into his mother’s slower-moving car.

The mother and her friend died at the scene, though her son didn’t initially know who he’d struck. He’s been in agony ever since, according to his father.
