A federal judge on Tuesday emphatically rejected Troy Anthony Davis’ claims that he was wrongly convicted of killing a Savannah police officer in 1989. U.S. District Judge William T. Moore Jr. said Davis failed to prove his innocence during a hearing ordered by the U.S. Supreme Court.

Four witnesses who testified against Troy Anthony Davis at his 1991 trial said Wednesday that none of their damaging testimony against him was true. The witnesses, whose prior testimony helped put Davis on death row for the killing of off-duty Savannah Police Officer Mark Allen MacPhail, said they were pressured by authorities to point the finger at Davis.
