ATLANTA (AP) -- Georgia's board of pardons says it considered "the totality of the information presented" in deciding to deny clemency to high-profile death row inmate Troy Davis.
The five-person board issued a statement after its decision was announced. It said members "have not taken their responsibility lightly."
The board's statement notes that it has commuted three death penalty cases since 2000 and "thoroughly deliberated" the Davis case.
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.
Davis has won high-profile support for his claim that he was wrongly convicted of killing a police officer in 1989.
