The Ford station wagon driven by civil rights activists Michael Schwerner, James Chaney, and Andrew Goodman that was discovered on June 23, 1964 following their disappearance. Its charred condition resulted in agents naming the case MIBURN, short for Mississippi Burning. They had been working with the "Freedom Summer" campaign to register African-Americans to vote. They were arrested for speeding, escorted to the local jail and held for a number of hours. They were released, but followed by law enforcement and others. Their car was pulled over, they were abducted, driven to another location, shot at close range and their bodies transported to an earthen dam and buried. Their bodies were discovered two months later thanks to a tip-off. During the investigation it emerged that members of the local White Knights of the KKK, the Neshoba County Sheriff's Office and the Mississippi Police Department were involved in the incident.
