Authorities identified the suspect as 57-year-old Vance Boelter, and the FBI issued a reward of up to $50,000 for information leading to his arrest and conviction.

A massive search was 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, an act Gov. Tim Walz called “a politically motivated assassination.

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