The N.C. Highway Patrol told multiple media outlets that 9-year-old Mequea Spears and 5-year-old Aiysha Spears of Bennettsville, S.C., were killed Tuesday when a Ford Explorer rear-ended their mother's Honda Civic.
The girls' mother, 31-year-old Andrea L. Purvis, and an 8-year-old child in her car were taken to hospitals for treatment.
The driver of the Explorer, 52-year-old John Dieter of Durham, was treated at the scene. Troopers say they do not plan to charge him.
All of the children were in child or booster seats.
