The man who authorities say impersonated a police officer and shot two state lawmakers north of the Twin Cities is believed to be 57-year-old Vance Boelter, multiple sources told the Associated Press.

MINNEAPOLIS—The suspect in the shooting of Minnesota lawmakers on Saturday was feeling down and unhappy with his work situation, but showed no signs that he could turn violent, his self-described best friend and part-time roommate said.

A two-day manhunt that left Minnesota in the United States on edge ended with the arrest of Vance Luther Boelter, who is accused of shooting two state lawmakers and their spouses. He killed senior Democratic assemblywoman Melissa Hortman and her husband Mark at their home on Saturday.
