A Buford man faces misdemeanor vehicular homicide charges in a five-vehicle wreck Sunday night that killed two people and injured eight others , including himself, on Interstate 985 North near Oakwood. William Robinson, 33, was driving a Ford F-150 that hit the Ford F-150 in front of him, which then caused a chain reaction that involved three other cars in front of those trucks, authorities said. All five vehicles were in the left lane. The driver of the other F-150, Virginia Hiscock, 66, and front-seat passenger William Hiscock, 55, both of Whitesburg, died. State patrol said in a Tuesday afternoon email that the Hiscocks’ truck was slowing and preparing to stop after the three cars in front of it had stopped. That’s when Robinson’s truck ran into the back of the Hiscocks’ truck, authorities said.
