2 people who rode with Wal-Mart gunman unaware of plan, police say
"Two people who were in a car with a U.S. airman when he drove to a North Dakota Wal-Mart and opened fire inside the store had no idea what he was going to do, police said Wednesday.
Grand Forks Police Lt. Derik Zimmel said Marcell Willis, 21, made up a reason to go to Wal-Mart around 1 a.m. Tuesday. The two people with him stayed inside the car while he went into the store, where he killed one worker and injured another near the self-checkout area in front of the store, then killed himself.
Police have yet to find a motive behind the shooting. Zimmel said the people who were with Willis also do not seem to know why he did it.
"To the best as we can tell at this point, they were as clueless as to his motives as anybody else," Zimmel said.
Zimmel did not reveal what ties the passengers had to Willis. He said authorities were treating them as witnesses, not suspects.
Police have identified the victims as Gregory Weiland, 70, of Grand Forks, who was killed, and Lis Braun, 47, also of Grand Forks, who was injured. Zimmel said authorities were not releasing the name of the third worker whom Willis shot at but missed."
