Ricky Bell, the warden at Riverbend Maximum Security Institution in Nashville, Tenn., gives a tour of the prison’s execution chamber on Wednesday, Oct. 13, 1999. Both the electric chair and the lethal injection gurney are kept in the room until the time is near for a prisoner to be executed and the one not used is taken out. Robert Glen Coe, the prisoner most likely to be the first executed in Tennessee since 1960, has chosen lethal injection over the electric chair. (AP Photo/Mark Humphrey)
