On June 21, 1964, three Freedom Summer activists disappeared. Weeks later, their bodies were found. They had been murdered by members of the local Ku Klux Klan - including some who were also police in the Neshoba County sheriff's department. When people were searching for their bodies in local swamps and rivers, they found the bodies of a 14-year-old boy and seven other men who also seemed to have been murdered at some time.
