<P> The three men had traveled from Meridian, Mississippi, to the community of Longdale to talk with congregation members at a church that had been burned . The trio was thereafter arrested following a traffic stop outside Philadelphia, Mississippi, for speeding, escorted to the local jail and held for a number of hours . As the three left town in their car, they were followed by law enforcement and others . Before leaving Neshoba County their car was pulled over and all three were abducted, driven to another location, and shot at close range . The three men's bodies were then transported to an earthen dam where they were buried . </P> <P> The disappearance of the three men was initially investigated as a missing persons case . The civil rights workers' burnt - out car was found near a swamp three days after their disappearance . An extensive search of the area was conducted by the Federal Bureau of Investigation (FBI), local and state authorities, and four hundred United States Navy sailors . The three men's bodies were only discovered two months later thanks to a tip - off . During the investigation it emerged that members of the local White Knights of the Ku Klux Klan, the Neshoba County Sheriff's Office and the Philadelphia, Mississippi Police Department were involved in the incident . </P> <P> The murder of the activists sparked national outrage and an extensive federal investigation, filed as Mississippi Burning (MIBURN), which later became the title of a 1988 film loosely based on the events . After the state government refused to prosecute, in 1967 the United States federal government charged 18 individuals with civil rights violations . Seven were convicted and received relatively minor sentences for their actions . Outrage over the activists' disappearances helped gain passage of the Voting Rights Act of 1965 . </P> <P> Forty - one years after the murders took place, one perpetrator, Edgar Ray Killen, was charged by the state of Mississippi for his part in the crimes . He was convicted of three counts of manslaughter in 2005 and was serving a 60 year sentence . On June 20, 2016, federal and state authorities officially closed the case and dispensed with the possibility of further prosecution . Killen died in prison in January 2018 . </P>
