BISMARCK, N.D. — An autopsy will determine if a man had drugs or alcohol in his system when he fatally shot one worker and injured a second before killing himself at a North Dakota Wal-Mart store, police said Wednesday.
"It's probably the next significant development in this case," Grand Forks Police Lt. Derik Zimmel said. He did not know when autopsy results would be available.
Police said the shooting at the store in Grand Forks a few minutes after 1 a.m. Tuesday may have been random. Investigators have found no link between the gunman, 21-year-old Marcell Willis, and the store or the employees whom he shot.
"There's no apparent motive that jumps out at this time," Zimmel said.
Willis was stationed at Grand Forks Air Force Base, about a dozen miles west of the city.
"We just need to plug away and talk to witnesses and compile information and continue to flip over stones and rocks and compile every scrap we can," he said.
Police on Wednesday identified the victims as Gregory Weiland, 70, of Grand Forks, who was killed, and Lisa Braun, 47, of Grand Forks, who was injured. Braun is in satisfactory condition, Altru Hospital spokesman Angie Laxdal said Wednesday. There was no timeline for Braun's release.
Zimmel said authorities were not releasing the name of a third worker whom Willis shot at but missed.
