Before April 1989, the State of Missouri's male death row was located at the Missouri State Penitentiary. Death row inmates were held in a below-ground unit and were isolated from other inmates. Death row inmates did not leave their special death row facility, and all services were brought into the unit. Each death row inmate was allowed one hour of exercise per day in a fenced area next to the death row facility. Missouri Department of Corrections said, "With restrictions on movement and limited access to programs, conditions of confinement for death row inmates mirrored those found in other states," and, "As with other states using prison facilities constructed before the turn of the [20th] century, conditions at Missouri State Penitentiary were less than favorable for both death row inmates and staff." After a legal challenge, the Missouri Department of Corrections began to use an internal death row classification system with privileges awarded by behavior, changed the medical services delivery procedures, and provided a "privacy room" where death row inmates could attend religious services.
