Police on Sunday arrested a man they believe assassinated Melissa Hortman, the top Democrat in the Minnesota House, in one of two shootings that targeted state lawmakers. The big picture: The massive manhunt for the 57-year-old suspect — what officials called the largest in state history — sent shockwaves through Minnesota and exacerbated security fears among elected officials.

Vance Boelter remains at large as the manhunt continues. Officials warn people public not to approach him if he's spotted.

The Minnesota Bureau of Criminal Apprehension reports that Boelter was last seen on Saturday morning in Minneapolis, after the shootings, wearing a light-colored cowboy hat, a dark long-sleeve shirt, and light pants while carrying a dark cross-body bag.
