The Georgia death row prisoner Troy Anthony Davis was killed by lethal injection last night after the U.S. Supreme Court refused to stop his execution. Supporters, ranging in the hundreds gathered outside the prison to the millions watching around the world, had held out hope as the Supreme Court weighed Davis’s last-ditch appeal for a stay of execution. Davis was convicted of the 1989 killing of an off-duty white police officer, Mark MacPhail. Since then, seven of the nine witnesses have recanted their testimony, and there is no physical evidence tying Davis to the crime scene. In the death chamber, witnesses reported Davis used his last words to maintain his innocence and wish peace upon his executioners. He was pronounced dead at 11:08 p.m. EDT, the cause listed as homicide.
