A proposed change in Missouri’s death penalty law is ready for passage by the Missouri House. It’s set to pass a bill that would ban executions of retarded persons in the state. The proposed law does not allow killers who are retarded to get away with the crime. It does allow for conviction but limits the maximum penalty to life in prison. This comes as Antonio Richardson awaits his execution, early Wednesday morning, for his part in the rape and murder of two sisters in St. Louis County a decade ago.
