JACKSON, Miss. (AP) — A black man says Edgar Ray Killen, a reputed Ku Klux Klan leader imprisoned for three civil rights workers’ deaths in Mississippi, gave him a power of attorney and land rights when they shared a penitentiary cell.

Former inmate James Stern said at a news conference Thursday that he also owns book and movie rights to Killen’s life story. Stern said he transferred 40 acres of Killen’s land last month to a nonprofit under his control.
