LINCOLN, Neb. (AP) — A man serving life in prison for a 2005 shooting death in Lincoln has lost his appeal to the Nebraska Supreme Court.

In a ruling Friday, the court rejected arguments by 34-year-old Antonio Banks. Banks had challenged his sentence with a motion for postconviction relief, which is filed once all other appeals are exhausted.

Banks was convicted of first-degree murder in the death of Robert Herndon. He also was sentenced to 20 to 30 years for a firearms conviction.

Banks argued in his motion that his attorney didn’t effectively defend him.
