A Gainesville man and woman along with three children were killed in a two-vehicle crash late Monday morning on Athens Highway at Oak Grove Road, according to Georgia State Patrol officials. Amanda Lynn Pardue, 34, and Robbie Adams Hollis, 52, both of Gainesville, died when their Ford Explorer crossed into the path of a tractor-trailer head-on. The children — ages 2, 8 and 13 — were also killed.
