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.

Boelter, 57, was arrested at about 9 p.m. June 15. He is accused of shooting the two Democratic state legislators and their spouses in the early morning hours of June 14. The Minnesota State Patrol took him into custody in rural Sibley County, roughly 50 miles southwest of Minneapolis.
