Authorities arrested and charged Vance Boelter on Sunday night after he allegedly shot and killed House Democratic leader Melissa Hortman and her husband in their Brooklyn Park home and shot and seriously injured state Sen.

Officers exchanged fire with Boelter, who fled inside the home before escaping. Officers then found the Hortmans inside suffering gunshot wounds. Melissa Hortman, 55, was pronounced dead at the scene, with Mark Hortman, 57, dying a short time later at North Memorial Hospital.

After what officials say was the largest manhunt in state history, Boelter was taken into custody Sunday night. He's facing charges of second-degree murder and second-degree attempted murder, but KARE 11's Lou Raguse says those charges will likely be upgraded to first-degree by a grand jury.

Suspected assassin Vance Boelter fronted a security firm his best friend said never existed and experienced “struggles” after returning from a three-year trip to Africa months before he allegedly turned his gun on a pair of Minnesota lawmakers and their spouses.
