Police in Grand Forks, North Dakota, are trying to find out what prompted a U.S. airman to walk into a Wal-Mart Supercenter and kill one worker, injure another and then fatally shoot himself.
“Right now, there are likely more questions than answers in many respects,” Lt. Derik Zimmel said.
Grand Forks police said the shooting a few minutes after 1 a.m. Tuesday may have been random, with no link yet found between Marcell Willis, 21, and either the store or the employees. Willis was stationed at Grand Forks Air Force Base, about a dozen miles west of the city.
“There’s no apparent motive that jumps out at this time,” Zimmel said.
Grand Forks Mayor Michael Brown said in a statement that the shooting shook the northeastern North Dakota city of about 55,000 people.
