** FILE ** Edgar Ray Killen is shown in a file photo from 1964. Killen, a reputed Ku Klux Klansman, was arrested late Thursday, Jan. 6, 2005, on murder charges in the 1964 slaying of three voter-registration volunteers, a case that is one of the last pieces of unfinished business from the civil rights era. Neshoba County (Miss.) Sheriff Larry Myers told The Associated Press that Killen was arrested at his home without incident. Myers said there would be more arrests in connection with the killings, which were dramatized in the 1988 movie &quot;Mississippi Burning.&quot; (AP Photo/Courtesy University of Missouri-Kansas City School of Law) BEST QUALITY AVAILABLE, 1964 FILE PHOTO Photo: Courtesy University Of Missouri-Kansas City School Of Law
