CHARLESTON, SOUTH CAROLINA—The renovation of an auditorium uncovered 37 sets of human remains thought to represent slaves or indentured servants buried between 1690 and the 1750s. Only one of the bodies had been buried in a coffin; the rest are thought to have been buried in shrouds. Buttons, coins, ceramics, gun flint, and iron objects were also found in the graves. When the investigation is completed, the Charleston City Council will decide where to reinter the remains.
