Minnesota state Rep. Melissa Hortman and her husband were killed, and state Sen. John Hoffman and his wife were wounded in politically motivated shootings overnight, Gov. Tim Walz said Saturday. Authorities have also identified a suspect who is still at large.

Authorities asked for the public’s help in finding Vance Boelter, 57, and South Dakota officials are seeking a ‘person of interest’ who may be traveling with him.
