A child was killed in a single-vehicle crash near Eustace. State Troopers say an SUV driven by 28-year-old Stacy Gale Laroche of Mabank failed to negotiate a curve, ran off the road and rolled several times. Paramedics flew Aviana Laroche, age seven, to a Dallas hospital where she was pronounced dead. A four-year-old girl was injured and two other children in the vehicle were not hurt.
