OMAHA, Neb. — A federal judge has denied a petition by a man seeking to be released from prison, where he’s serving decades for the 2004 shooting death of a Nebraska soccer player.

Lucky Iromuanya was convicted of second-degree murder for the death of 21-year-old Jenna Cooper, a starting University of Nebraska-Lincoln soccer player. He was initially sentenced to life, but the Nebraska Supreme Court reduced his sentence to 70 years to life.

Iromuanya filed for habeas corpus, or relief from illegal detention, in Nebraska’s federal court after failing in other state appeals.

On Thursday, U.S. District Court Judge Joseph Bataillon rejected the petition, saying Iromuanya is not being unlawfully imprisoned.
