Two defense lawyers say Georgia's board of pardons Tuesday morning rejected a bid to spare the life of Troy Davis, who has attracted high-profile support for his claim that he was wrongly convicted of killing a police officer in 1989.
Davis' supporters made a last-ditch effort on Monday to stop his execution by telling the pardons board that he's innocent and requesting clemency.
Davis is scheduled to die Wednesday. He was convicted of the 1989 killing of police officer Mark MacPhail, who was working as a security guard when he was shot to death.
Since then, eyewitnesses have recanted or backed off their testimony and others have said another man at the scene admitted to the shooting.
Davis has gained high-profile supporters such as the pope and a former U.S. president.
Prosecutors and MacPhail's family urged the board let the execution occur.
