An armed Vance Boetler was spotted in military gear in the Green Isle area Sunday night. Authorities are asking people to shelter in place.

The suspect, identified by authorities as Vance Luther Boelter, posed as a law enforcement officer to gain access to the victims' homes.

Minnesota state Rep. Melissa Hortman and her husband were killed, and state Sen. John Hoffman and his wife were wounded in politically motivated shootings early Saturday, Gov. Tim Walz said. Authorities have also identified a suspect who is still at large.
