In 1964, community activists from
Congress of Racial Equality and
Students for a Democratic Society launched
Freedom Summer. Later that year, three of these activists—
James Chaney,
Michael Schwerner, and
Andrew Goodman—were murdered. Sam Bowers was convicted in 1967 for his role in the Chaney–Schwerner–Goodman killings and served his sentence at
McNeil Island Federal Prison in
Washington. He was released in 1976 and then worked as a Sunday School teacher. Two other men,
Charles Eddie Moore and
Henry Hezekiah Dee, were murdered at that time because they were suspected of being civil rights activists. However, it was later determined that Bowers was not involved in their deaths. Klansman and former police officer
James Ford Seale was arrested for this crime in 2007.
Charles Marcus Edwards also participated in the abduction and beating and testified that he was the one who had identified Dee as a target because "he fit the profile of a
Black Panther..." Seale and Edwards were convicted because journalists, particularly Canadian filmmaker
David Ridgen in his award-winning
CBC documentary
Mississippi Cold Case, investigated the case and discovered incriminating evidence. In January 1966, Bowers, along with several other members of the White Knights of the KKK, was subpoenaed by the
House Un-American Activities Committee to testify about Klan activities. Although
Byron De La Beckwith gave his name when asked by the committee (but would answer no other substantive questions), other witnesses, such as Bowers, invoked the
Fifth Amendment even in response to that question. In 1966, alleged members of the White Knights firebombed the house of
Vernon Dahmer, a civil rights activist who was working to register African Americans for the vote. Dahmer died of burn injuries, which covered 40% of his body, and damage to his lungs, which were seared while rescuing his family from the fire. According to later testimony by ex-White Knights member
T. Webber Rogers, Bowers gave the direct order to have Dahmer killed "in any way possible." After four previous trials ended in deadlock (a 1968 jury split 11 to 1 in favor of guilty, and in 1969 a jury split 10–2 in favor of conviction), Bowers was convicted of the murder in August 1998 and sentenced to life in prison. In 1967, White Knights were alleged to have begun a campaign against Jewish targets in Mississippi.
Beth Israel Congregation in
Jackson and
Congregation Beth Israel in
Meridian were bombed. Also, the home of Jackson's Rabbi
Perry Nussbaum was attacked. The actual perpetrators of these crimes were suspects
Thomas A. Tarrants III and
Kathy Ainsworth. The
FBI became involved in the case and, with threatening accusations against local law enforcement, began tracking down potential bombers. A breakthrough in the case came when two Klan brothers,
Alton Wayne Roberts and Raymond Roberts, met with the FBI and the police in exchange for reward money and immunity. Alton Wayne Roberts had previously been sentenced to 10 years in prison for violating the civil rights of Chaney, Schwerner, and Goodman. He agreed to cooperate to receive a reduced sentence. A joint FBI and local police operation ambushed Tarrants and Ainsworth. Ainsworth was killed, and Tarrants was severely wounded. ==Conviction and death==
