MIAMI (AP) -- Florida is preparing to execute the leader of an escape attempt that left a prison guard dead.
William Van Poyck is scheduled to be executed Wednesday at Florida State Prison for the 1987 murder of guard Fred Griffis.
Van Poyck and Frank Valdes ambushed a prison van outside a West Palm Beach doctor's office in a failed attempt to free James O'Brien. Griffis was fatally shot after he threw the van's keys into the bushes to foil the escape. Van Poyck and Valdes were captured following a car chase. Valdes was stomped to death in prison in 1999. Seven guards were charged with his death, but none were convicted.
The 58-year-old Van Poyck has claimed Valdes fired the fatal shot. Prosecutors say that's irrelevant since Van Poyck planned the attack.
