STARKE, Fla. (AP) -- The U.S. Supreme Court has denied an emergency request for a stay in the scheduled execution of a Florida mass killer who sought a reprieve because of mental illness.
The justices rejected the request Tuesday from 64-year-old John Errol Ferguson, who has been on Florida's death row for 34 years. Ferguson's lawyers contend his mental illness should prevent his execution.
The execution was scheduled for Tuesday evening.
Ferguson was convicted of killing eight people in South Florida in the 1970s, including a teenage couple, and was a prime suspect in another double slaying. Previous judges have ruled that he is legally competent to be executed even though he suffers from paranoid schizophrenia.
