In Mississippi, the trial begins today of Edgar Ray Killen in connection to the murder of three civil rights workers 41 years ago during the Freedom Summer voter registration drive. In June 1964 — Michael Schwerner, Andrew Goodman and James Chaney — were shot dead allegedly by members of the Ku Klux Klan. The 80-year-old Killen is believed to have been the mastermind behind the killings.
