STARKE, Fla. (AP) -
A mass murderer from Miami-Dade County is scheduled to die by lethal injection at Florida State Prison.
John Errol Ferguson is set for execution at 6 p.m. Monday.
The 65-year-old was convicted of killing eight people in South Florida in two separate incidents.
Gov. Rick Scott initially signed Ferguson's death warrant last fall, scheduling him to die Oct. 16. But appeals at the state and federal level kept the execution from moving forward. Ferguson's lawyers have filed numerous appeals in several courts. They contend their client is mentally ill and has suffered from schizophrenia since he was a teen.
Ferguson's lawyers say several psychiatrists have ruled over the years that Ferguson is mentally ill. Most of those evaluations came when Ferguson was in a state mental hospital in the 1970s.
