In the summer of 1964 more than 20 members of the Ku Klux Klan murdered three civil rights workers in a tragic episode of racial injustice that would become known as the “Mississippi Burning” case. The identities of the killers, which included a sheriff’s deputy, were an open secret, but charges were never brought until newspaper journalist Jerry Mitchell started to work on it.
