A convicted murderer pleaded not guilty Friday to selling the gun that was used to kill ex-NFL quarterback Steve McNair. Adrian Gilliam of La Vergne, Tenn., was charged last month with being a convicted felon in possession of a firearm. According to court documents, he admitted selling a loaded 9 mm Bryco/Jennings semiautomatic pistol for $100 to Sahel Kazemi. Source: Associated Press
