A 41-year-old felon will return to prison for four years for illegally possessing a gun. Zan Morgan pleaded guilty to the federal charge last May. Eau Claire police stopped the vehicle Morgan was driving last year. Officers said they smelled a strong odor of marijuana and, when they started to conduct a search, Morgan told them he had a gun under the driver’s seat. The Eau Claire man has a lengthy criminal record dating back at least 15 years.
