In 1964, a mob of Klansmen murdered three civil rights workers in the small Mississippi county of Neshoba - the infamous "Mississippi Burning" murders. The young men, two Jews from New York and an African-American from Mississippi, were in the Deep South helping to register African-American voters during what came to be known as the Freedom Summer. Although the killers bragged about what they did, it took the State 40 years to indict the mastermind, Edgar Ray Killen, an 80-year-old Baptist preacher and notorious racist.
