The headstone of Arthur S. Thompson, found last week lying in the middle of a busy highway in Statesboro, has been recovered by family members, but the mystery of how it got there in the first place remains. The headstone was found several miles away from where it was originally placed in an Emanuel County cemetery. Henry Thompson of Swainsboro arrived at the Statesboro Herald office Wednesday morning to retrieve his father’s headstone, but he said he has no idea how the heavy marker found its way to Northside Drive West in front of Boyd’s Barbecue.
