The Freedom Summer Murders
6/21/1964 – Three civil rights workers are murdered in Neshoba County, Mississippi, United States, by members of the Ku Klux Klan. Andrew Goodman, James Chaney and Mickey Schwerner, had been working with the Freedom Summer campaign by attempting to register African Americans in Mississippi to vote. This registration effort was a part of contesting over 70 years of laws and practices that supported a systematic policy of disenfranchisement of potential black voters by several southern states that began in 1890.
In 2005, Edgar Ray Killen, who had previously been acquitted for the murders of James Chaney, Andrew Goodman, and Mickey Schwerner, is convicted of manslaughter 41 years afterwards (the case had been reopened in 2004).
