TALLAHASSEE, Fla. (AP) - The Florida Supreme Court has upheld a lower court's ruling that a former escort service owner is sane enough to be executed.
    
In an eight-page ruling released Tuesday, the court wrote that a judge in the Eighth Circuit was correct in finding Marshall Lee Gore competent.
    
Gov. Rick Scott signed a death warrant for Gore on May 13. Gore had been scheduled to die in July by lethal injection. But a judge halted Gore's execution to consider whether he's mentally ill.
    
Gore's lawyer maintains that his client is insane.
    
Gore was convicted in the 1988 slaying of Robyn Novick, a 30-year-old exotic dancer. In addition to Novick, Gore also was sentenced to death for the 1988 slaying of Susan Roark.
