UNDATED, Miss. (WCBI)-He murdered three civil rights workers in 1964 and now says he was denied his civil rights in his Mississippi trial.
Former Ku Klux Klan member Edgar Ray Killen is seeking a new trial before the Supreme Court.
Killen has attempted two trials on the same argument previously, but lost his appeal both time.
Killen was convicted of manslaughter in 2005 41 years after the deaths of Michael Schwerner, Andrew Goodman, and James Chaney.
The state prosecution had until the close of today’s business day to respond to Killen’s petition before the Supreme Court.
He is currently serving a 60 year sentence.
