In September of 1937, Governor Lloyd Crow Stark signed a bill calling for execution by lethal gas. No longer would the local sheriff be responsible for carrying out the death penalty for those convicted in his county. The days of public hangings in Missouri were to finally come to an end. Many members of the legislature were strongly opposed to the bill and argued that more death sentences would result. Nevertheless, Missouri was, on the whole, a state that supported the death penalty for serious crimes. The bill was changed to lethal gas instead of the electric chair, and passed. In total, 40 inmates were put to death in the gas chamber between 1937 and 1989 when MSP death row ended and all capital punishment inmates were moved to the new prison at Potosi.
