BONNE TERRE, Mo. (AP) — Missouri's oldest death row inmate has been put to death for the 1996 killing of a sheriff's deputy. Cecil Clayton's execution Tuesday came after the U.S. Supreme Court and the governor declined to spare the 74-year-old, who was missing part of his brain from a 1970s sawmill accident. His attorneys said he had a diminished mental capacity and dementia. Clayton was convicted of gunning down Christopher Castetter, a 29-year-old sheriff's deputy.
