The attorney for 29-year-old convicted shooter Michael Carneal argued Wednesday before the panel in Cincinnati that his client's appeal was timely and should be allowed to proceed.
Carneal has been diagnosed with schizophrenia and is arguing that he wasn't mentally competent to plead guilty to the shooting at the time, when he was 15.
The Kentucky Attorney General's Office countered by saying that Carneal filed the appeal too late and that his conviction and life sentence should stand.
The panel is now considering the matter but may not issue an opinion for months.
