Warren Hill Update: Georgia inmate scheduled to be executed Monday evening

(CBS/AP) JACKSON, Ga.-- A prisoner who has twice come within hours of death on Georgia's death row is once again facing execution.

Warren Lee Hill, who was sentenced to death for the 1990 beating death of fellow inmate Joseph Handspike, is scheduled to be executed at the state prison in Jackson at 7 p.m. Monday.

Authorities said Hill bludgeoned Handspike with a nail-studded board while his victim slept.

Hill has come within hours of death twice in the past year before scheduled executions were halted by last-minute court orders.

Hill's lawyers have long argued that Hill is mentally disabled and therefore should not be put to death because the execution of mentally disabled offenders is prohibited by state law and a 2002 U.S. Supreme Court decision.
