(AP) — A man serving life in prison for shooting another man to death at an Omaha restaurant drive-thru has again been denied his request for DNA testing of evidence gathered in the case.

Antoine Young appealed after a Douglas County District Court in 2012 denied his request to conduct DNA testing of a black sweatshirt and shell casings found at the scene of the 2007 shooting that killed Ray Webb. Young maintains that testing will show that genetic material on those items came from someone else.

On Friday, the Nebraska Supreme Court upheld the lower court’s denial, saying Young did not request the testing at his 2008 trial and offered no evidence that such testing was not available at the time of his trial — as required by state law.
