Authorities searched a vehicle on a rural road outside Minneapolis that they believe had been used by the man wanted in the shootings of two Democratic lawmakers.

A massive search has stretched 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 and injured another.

The search for Vance Luther Boelter, the FBI-wanted man who is suspected of shooting two Minnesota lawmakers and their spouses at their residences in the early hours of Saturday morning, is well into its second day.
