The Nebraska Supreme Court has rejected the latest appeal by a man convicted of killing a University of Nebraska at Omaha student whose body has never been found.

The high court Friday upheld a lower court's denial of Christopher Edwards' second motion for post-conviction relief. The court found that Edwards' appeal saying the lower court should have held an evidentiary hearing on his claim that his attorney was ineffective was filed too late.

Edwards was convicted of second-degree murder in the 2006 disappearance of 19-year-old Jessica O'Grady, whose body was never found. Edwards was sentenced to 100 years to life.

The high court rejected Edwards' first post-conviction relief motion in 2012. In that motion, Edwards argued that a corrupt Douglas County crime scene investigator planted blood evidence to frame him.
