Suspect's vehicle found in Sibley County as search intensifies for Vance Luther Boelter, wanted in connection with fatal shooting of Minnesota lawmakers in targeted attack.

Surveillance footage captured an attempted murder, according to charges unsealed Sunday: A man wearing a mask, a blue shirt and police-style tactical vest with a badge knocked on a door in Champlin and announced himself as a police officer. He then entered the house and shot Minnesota Sen. John Hoffman and his wife.

Authorities are investigating reports of "targeted shootings" in suburban Minneapolis in what Minnesota Gov. Tim Walz said was an "ongoing situation." The shootings were in Champlin and Brooklyn Park, two neighboring cities about 10 miles from downtown Minneapolis, Walz said Saturday morning.
