An elderly former member of the Ku Klux Klan has been convicted of manslaughter more than forty years after a triple murder in Mississippi.Edgar Ray Killen, 80, a sawmill operator and Baptist preacher, was accused of orchestrating the killings of three civil rights campaigners in the summer of 1964. It is not the first time Killen has stood trial. In 1967, he was among a group of men tried for violating the same three mens’ civil rights, but was never found guilty after one juror said she could not convict a preacher. He was arrested again earlier this year after the case was reopened. Michael Schwerner, Andrew Goodman and James Chaney, all in their 20s, were abducted and shot by a group of Klansmen in Mississippi. It was a case that outraged the United States and strengthened the civil rights movement.
