An eastern Iowa man has been charged with first-degree murder for a shooting that killed his nephew. The Quad-City Times reports that 51-year-old Brian Francisco Duque, of Riverdale, was being held without bond at Scott County Jail. Authorities say they were called to a house shortly before 1:30 p.m. Saturday. Sheriff’s deputies attempted to revive 32-year-old Terry Warner, but he had already died from his wounds. According to an arrest affidavit, Duque was arguing with Warner, his nephew who also lived at the house. Duque allegedly grabbed a 9-millimeter handgun from his bedroom and shot Warner once.
