An autopsy performed today on a badly decomposed body found in downtown Macon did not determine the cause of death.
Bibb County coroner Leon Jones said toxicology tests will have to be performed on David Mossbarger, 52, as there were no visible signs of trauma or injury on the body.
Mossbarger was found dead inside the old Caduceus Occupational Medicine building not far from the entrance to Macon's Central City Park.
A vial of prescription drugs with Mossbarger's name on the label was found next to the body, Jones said.
He had been dead about a week before his body was discovered by a guard on a prisoner work detail Thursday morning.
