A 70-year-old white supremacist twice tried and acquitted of the 1963 slaying of civil rights leader Medgar Evers has been jailed without bond, again accused of the killing.

Byron De La Beckwith was arrested Monday at his Signal Mountain home on a governor's warrant charging him with first-degree murder in Evers' death. He quickly filed a motion questioning the validity of the warrant, signed by the governors of Mississippi and Tennessee.A hearing on the motion is scheduled Wednesday before Hamilton County Criminal Court Judge Joe DiRisio, who could turn Beckwith over to Mississippi authorities if he finds the warrant in order.
