A 47-year-old man is suspected to be the shooter in a bar confrontation Saturday night.
Police said the suspect in the shooting case came to Jim's Sports Club Bar and Grill to confront his ex-wife.
The suspect left the bar after being confronted by a patron only to return with a gun. He shot Edward Walberg, 40, and two other men. Walberg died and the one other victims' injuries are not life threatening.
It was later reported by WCCO that the suspect was a police officer between 1983 and 1989 before taking a job at the city's water department.
The second victim, Cale Nelson, 29, is reportedly "fighting for his life," according St. Mary's Medical Center in Duluth. Nelson was the bar patron who originally tried to intervene before the suspect returned with a gun.
An investigation is still going for this case.
