ATLANTA — Two defense lawyers say Georgia's pardons board has rejected clemency for Troy Davis, who has attracted high-profile support for his claim that he was wrongly convicted of killing a police officer in 1989.

The Board of Pardons and Paroles on Tuesday rejected Davis' request for clemency after hearing hours of testimony from his supporters and prosecutors. That's according to two of Davis' lawyers, Stephen Marsh and Brian Kammer. There was no immediate word from the board.

Davis is set to die on Wednesday for the killing of off-duty Savannah officer Mark MacPhail, who was slain while rushing to help a homeless man being attacked. It is the fourth time in four years his execution has been scheduled by Georgia officials..
