Provenzano was convicted and sentenced to death for the January 1984 courthouse murder of Orange County Circuit Court bailiff William Arnold Wilkerson. He also was convicted of attempting to murder bailiffs Harry J. Dalton and Mark L. Parker. Provenzano is scheduled for execution Sept 24. In this case, his attorneys argue that he is incompetent to be executed and thus cannot be sent to the electric chair under U.S. Supreme Court cases barring execution of the insane. On the date this document was distributed (9/9/99), a separate appeal by Provenzano was pending in this Court alleging that prior alleged malfunctions of the electric chair have rendered it cruel and unusual, and thus unconstitutional.
