OMAHA, Neb. (AP) — The Nebraska Supreme Court has affirmed the conviction and sentence of an Omaha man serving up to 60 years in prison for a fatal parking lot shooting.

Rufus Freemont was convicted last year of second-degree murder and weapons counts for the June 2010 shooting death of 19-year-old Andrew Galligo.

Freemont argued that a Douglas County District Court erred by, among other things, allowing evidence at his trial that he had a gun in the week before the shooting and that he jumped out of a second-story window to escape police trying to arrest him.

A Nebraska Supreme Court opinion issued Friday said the lower court did err by allowing testimony on Freemont’s gun possession, but that the error was harmless.
