Investigative reporter Jerry Mitchell writes for The Clarion-Ledger in Jackson, Miss., and specializes in unearthing new evidence from Civil Rights era criminal cases. His coverage has led to the convictions of four Ku Klux Klan members, starting with Byron De La Beckwith for the assassination of Medgar Evers. Recently, Edgar Ray Killen was found guilty of orchestrating the murders of Civil Rights workers Andrew Goodman, James Chaney and Michael Schwerner. Next week Mitchell will be honored with the John Chancellor Award for Excellence in Journalism.
