(AP Photo/Seth Perlman) (Newser) – A 24-hour Walmart Supercenter in Grand Forks, ND, was rattled by a shooting in the wee hours this morning that left two people, including the gunman, dead. Though police did not provide information about the gunman or victims, Grand Forks Air Force Base issued a statement saying an airman was involved in the shooting, which occurred around 1:04am; it did not elaborate. "We do not believe there is any further risk to the public," police Lt. Derik Zimmel tells the AP. Though he did say the shooter was the only person with a gun and that no police officers fired a weapon, he would not go as far as to say the gunman shot himself, and he provided no details of what led to the shooter's death. A third person was taken to a hospital with gunshot wounds that were not believed to be life-threatening, Zimmel says. He adds that police are working to determine a motive. WDAZ talked to a witness who reported hearing "popping sounds" in the store. When he left the store he spotted a bloodied Walmart employee, he says. The Walmart is one of two in the northeastern North Dakota city of about 55,000 people. Zimmel did not have information on how many workers and customers were in the store at the time.
