GRAND FORKS, N.D. (AP) - The Wal-Mart store in Grand Forks where a U.S. airman killed one worker and injured another before killing himself has reopened after being closed for two days.

Wal-Mart spokesman Brian Nick says the store opened Thursday morning. Dozens of people turned out for a vigil outside the store Wednesday evening.

Authorities say 21-year-old Grand Forks Air Force Base Senior Airman Marcell Willis walked into the store early Tuesday and shot and killed 70-year-old overnight cashier Gregory Weiland. Willis then shot and wounded 47-year-old overnight grocery general manager Lisa Braun, who's recovering in a hospital. Willis then killed himself. His motive isn't known.

Weiland's funeral is scheduled Saturday at St. Michael's Catholic Church in Grand Forks. He'll be buried at St. Bernard's Catholic Cemetery in Thief River Falls, Minnesota.
