During the "Freedom Summer" of 1964, James Chaney, 21, a young black man from Meridian, Mississippi and Andrew Goodman, 20, and Michael Schwerner, 24, two Jewish men from New York, were murdered in Philadelphia, Mississippi. Killen, along with Cecil Price, then deputy sheriff of Neshoba County, was found to have assembled a group of armed men who conspired against, pursued, and killed the three civil rights workers. Samuel Bowers, who served as the Grand Wizard of the local White Knights of the Ku Klux Klan and had ordered the murders to take place, acknowledged that Killen was "the main instigator".
