(CNN) -- James Ford Seale, a reputed former member of the Ku Klux Klan convicted in the 1964 abduction and killings of two African-American teenagers in Mississippi, has died in federal prison, the Federal Bureau of Prisons said. He was 75. Seale died on Tuesday in the Federal Correctional Institution at Terre Haute, Indiana, said bureau spokesman Chris Burke, but he did not provide further details. A jury in 2007 convicted Seale, a former sheriff's deputy, of kidnapping and conspiracy to commit kidnapping in the disappearances of Charles Eddie Moore and Henry Hezekiah Dee, both 19. The bodies of both youths were found in a backwater area of the Mississippi River. Seale was serving three life sentences.
