Attorneys for the 56-year-old Panetti asked that his execution be stayed and counsel and mental health experts appointed to further the claim that he is mentally incompetent to be executed. Kathryn Kase, executive director of Texas Defender Services and one of Panetti's lawyers, said the convicted killer is "hearing voices, believes that a listening device has been implanted in his tooth and that the state wants him to 'shut up' about corruption and death row and stop him from preaching the gospel."
