*Unfortunately it looks like it’s about to be all over for Troy Anthony Davis, the high-profile Georgia death row inmate who claims he’s innocent of killing a Savannah police officer.

According to reports, the Department of Corrections said Wednesday that Davis, 41, will be executed at 7:00 p.m. EDT on Sept. 21 for the 1989 slaying of Mark MacPhail.

It’s the fourth time since 2007 that state officials have set a date to execute Davis. The order comes after the U.S. Supreme Court cleared the way for the execution by refusing to overrule a federal judge who decided Davis failed to clear his name after getting a rare chance to prove his innocence.
