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.

Melissa Hortman, a former Minnesota House Speaker, and her husband were fatally shot early Saturday in their Brooklyn Park home. The second state lawmaker, Sen. John Hoffman, and his wife were shot multiple times in nearby Champlin.

A day after police say a gunman killed a Minnesota state lawmaker and her husband, plus wounded another lawmaker and his wife, suspect Vance Boelter remains on the run.
