A 31-year-old Austin man was sentenced to three years in prison Thursday for standing off with police one night in September.

Andrew Michael Larson was sentenced on one count of second-degree assault with a dangerous weapon.

According to a court complaint, Austin police were called to the 1400 block of 10th Avenue NW around 10:30 p.m. on Sept. 3, 2011, on a report of an assault with a gun.

When police arrived, they met with three men, two of whom said they witnessed Larson firing a shotgun. One of the men, Larson’s roommate, said he and Larson had been arguing earlier but the argument ended, and Larson left in his car.

In the meantime, Larson’s roommate reportedly left, too, leaving the other two men there alone. According to the court complaint, Larson came back shortly after his roommate left, approached the two remaining men and said, “What’s up? You got a problem or something?” Larson pointed the gun at one of the men and fired, but the man told police he was able to dart behind a tree before Larson pulled the trigger, according to court documents.

The men told officers Larson went into the house after firing the gun.

According to the court complaint, officers from the Austin Police Department, Mower County Sheriff’s office, Minnesota State Patrol and the Special Incident Response Team set a perimeter around the house to get Larson to surrender. SIRT spent several hours attempting to contact him, and he surrendered shortly after 6 a.m. Sunday.

After arresting Larson, officers matched the shotgun shell casings from outside the house with those in the gun. The gun was found in a crawl space in Larson’s bedroom, according to court documents.

Larson told police he “would not have shot anybody.” He said he didn’t recall shooting the gun, but later said he has no idea why he shot it and that it was “stupid.”
