Brooklyn Park police Sgt. Rielly Nordan had just wrapped up his shift early Saturday morning when he heard that Champlin police were responding to a shooting at a home — and one of the victims was a state senator.

Boelter was arrested in a field located in a rural part of Sibley County, in southwest Minneapolis, and he was being interviewed at a law enforcement facility, Drew Evans, the superintendent of the state’s Bureau of Criminal Apprehension, said.
