PHOENIX (AP) -- The U.S. Supreme Court has refused to consider an appeal filed on behalf of an Arizona death row inmate convicted of the 1986 killing of a Nevada man. The high court on Monday rejected the appeal for Graham Sanders Henry. Henry was sentenced to die for killing Las Vegas-area resident Roy Estes. The victim was driven to the desert north of Kingman in Arizona's Mohave County where he was stabbed in the heart and his throat cut. The 9th U.S. Circuit Court of Appeals said in an April ruling that finality is long overdue in a case that it said involved "ghastly crimes" by Henry.
