Authorities mobilized state and local police, SWAT teams and K-9 units across multiple counties while urging the public to remain alert and avoid approaching Boelter, in what police called the bigges...

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.

Police identified the suspect, who remained at large Saturday, as 57-year-old Vance Luther Boelter.

A manhunt is underway after the fatal shooting of Minnesota state Rep. Melissa Hortman and her husband overnight. State Sen. John Hoffman and his wife were also injured in what Gov. Tim Walz called "politically motivated" shootings.

Melissa Hortman, the former Minnesota House speaker felled by an assassin’s bullet at her home on Saturday, really did understand what democracy looks like.
