The Southern Ohio Correctional Facility is the primary facility for executions in Ohio. The prison had repeatedly had issues with overcrowding and overly strict guards. By April of 1993, the prisoners decided to take matters into their own hands. Nearly 500 prisoners rose up and took control of the facility for nearly two weeks, taking several guards as hostages, intending to use them to negotiate for improved conditions. When the prisoners’ stipulations weren’t met, some of the leaders discussed killing one of the guards. Before a consensus could be reached, one of the prisoners strangled Corrections Officer Robert Vallandingham. Four inmates were sentenced to death for his murder.
During the takeover, nine other inmates were killed, most of which were known to be informants.
