A massive search is stretching into its second day for a man who authorities say posed as a police officer and fatally shot a Democratic state lawmaker in her suburban Minneapolis home.

Vance Boelter was captured in a wooded area on Sunday night, and charged in the shootings of two state lawmakers and their spouses. He appeared in federal court after being charged with murder.

Minnesota officials said they are searching for Vance Luther Boelter, who was last seen in the Twin Cities area.
