Three people were killed and three others injured in a single-vehicle crash Sunday afternoon east of Anderson. Investigators believe the sport-utility vehicle was speeding south on County Road 600 West near Daleville about 4 p.m. when the driver hit a rise in the road and lost control. The SUV became airborne, struck a retaining wall, and flipped for a couple of hundred feet before stopping. Killed in the crash were driver Lisa Case, 46, of Anderson, and passengers Kent Kalley, 46, and Andrew Lackey, 12, both of Yorktown. The three other passengers, all 13, were in stable condition.
