John Graham arrives Friday, Dec. 7, 2007, at the federal courthouse in Rapid City, S.D. Four years after his arrest for the 1975 killing of a fellow American Indian Movement activist, Graham pleaded not guilty at his first court appearance Friday in U.S. District Court, a day after his last attempt at a Canadian appeal failed. He was extradited from Vancouver, British Columbia, to stand trial for the 1975 slaying of Anna Mae Pictou Aquash on the Pine Ridge Indian Reservation. (AP Photo/Carson
