Olen Lavelle Burrage was a Mississippi farmer and businessman. He was alleged to have been linked to the murders of Chaney, Goodman, and Schwerner who were murdered by the Ku Klux Klan in June 1964. The bodies of the Civil Rights workers were found buried in an earthen dam that was under construction on a farm owned by Burrage.

Alton Wayne Roberts was an American murderer and white supremacist. Roberts, a member of the White Knights of the Ku Klux Klan, was convicted for his role in the 1964 Freedom Summer murders. He was the one who fatally shot two of the victims, Congress of Racial Equality civil rights activists Michael Schwerner and Andrew Goodman. Roberts also shot the third activist, James Chaney, but it is debated by some that it was another accomplice, James Jordan, who had killed him. Jordan had identified Roberts as Chaney's killer. In 1967, he was charged and convicted of depriving the slain activists of their civil rights.
