2005: Former Ku Klux Klan organizer Edgar Ray Killen is found guilty of three counts of manslaughter on the 41st anniversary of the slaying of three civil rights workers in Mississippi. He would be sentenced to 60 years in prison two days later. Killen's arrest on Jan. 6, 2005, marked the first time that anyone had faced state prosecution for the murders of the three volunteers, who were abducted and then killed on a remote road outside Philadelphia, Mississippi. The volunteers, all in their 20s, died while working to register black voters during the so-called Freedom Summer civil rights campaign in the once-segregated southern state. Their story was dramatized in the 1988 movie "Mississippi Burning."
