NASHVILLE, Tenn. (AP) _ Prosecutors in Nashville will get another chance to show that a man facing murder charges is competent to be executed.

Criminal Court Judge Monte Watkinson on Friday granted another hearing in the case of 26-year-old Christopher Lee Davis. Davis is charged with robbing and slaying Iraq War veteran Herbert Clayton in 2007.

Watkins had already ruled that Davis was ``intellectually disabled'' and, therefore, ineligible for the death penalty. But prosecutors dispute the psychology report used in that decision and want a chance to put up their own expert to prove otherwise.

Clayton's fiancee, Jannie Traylor, told The Tennessean she was happy with the decision and is eager for the case to finally get to trial.
