OMAHA, Neb. (AP) — A judge has denied a new trial for an Omaha man convicted of killing a college student whose body has never been found.

Douglas County District Judge J. Russell Derr on Friday rejected Christopher Edwards’s plea for a new trial.

Edwards was convicted of second-degree murder in the 2006 disappearance of 19-year-old Jessica O’Grady and was sentenced to 100 years to life in prison. Edwards has maintained he’s innocent and that David Kofoed, former commander of Douglas County crime scene investigation unit, planted some of the evidence used to convict him.

In 2012, the Nebraska Supreme Court granted a new hearing for Edwards, based on the claim that he was framed.

But on Friday, the judge rejected that claim.
