Surveillance footage captured an attempted murder, according to charges unsealed Sunday: A man wearing a mask, a blue shirt and police-style tactical vest with a badge knocked on a door in Champlin and announced himself as a police officer. He then entered the house and shot Minnesota Sen. John Hoffman and his wife.

Vance Luther Boelter, 57, was arrested on Sunday for allegedly killing a Minnesota Democratic state lawmaker and her husband while posing as a police officer, Governor Tim Walz said.

Amid the horror and senseless violence in the shootings of Rep. Melissa Hortman and Sen. John Hoffman and their spouses, there are stories of heroism.

Minnesota State Rep. Melissa Hortman, State Sen. John Hoffman and their spouses were all shot early Saturday in targeted attacks.

"Hi everyone! I’m looking to get back into the U.S. Food Industry and I'm pretty open to positions," Boelter wrote on LinkedIn last month.

Minnesota Sen. John Hoffman's wife shared an update after a shooting injured the couple at their home early Saturday morning. The family also shared a statement after the suspect was taken into custody.

Lawmakers are still reeling from the shooting that killed one Minnesota state legislator and her husband and severely wounded another and his wife.
