Accused Minnesota assassin Vance Boelter's alleged plan to kill more politicians on his target list was foiled by a police sergeant's proactive hunch.

The suspect, identified by authorities as Vance Luther Boelter, 57, was arrested after state Rep. Melissa Hortman and her husband, Mark, were shot and killed, and State Sen. John Hoffman and his wife, Yvette, were shot multiple times and wounded in Brooklyn Park and Champlin, two neighboring suburban cities 10 to 20 miles outside Minneapolis.

Vance Luther Boelter, the subject of a continued manhunt as of Saturday afternoon, is listed as director of security patrols for Praetorian Guard Security Services. Authorities say the suspect in the shootings was impersonating a police officer.
