Georgia prisoner Troy Davis was executed just after 11 p.m. Wednesday night after the U.S. Supreme Court decided not to block his execution during a last-minute plea by Davis's lawyers. Davis’s execution had been scheduled to occur at 7 p.m. Wednesday but had been delayed for several hours while the Supreme Court reviewed the case. Shortly after 10 p.m., the high court announced it had denied a stay of execution. Davis, 42, was convicted in the 1989 killing of a Savannah police officer, but he has always maintained his innocence. His case has become a rallying cry for anti-death-penalty advocates, since seven of the nine witnesses who testified against him have since recanted their testimony.
