A massive search in the United States for a man who authorities say posed as a police officer and fatally shot a Democratic state lawmaker in Minnesota has stretched into a second day, with the state’s governor calling it “a politically motivated assassination”.

The suspect, identified as 57-year-old Vance Luther Boelter, also allegedly shot and wounded a second Democratic lawmaker and his wife, according to law enforcement officials and the FBI.

The large-scale manhunt entered its second day on Sunday after Boelter allegedly killed former Minnesota House Speaker Melissa Hortman and her husband, Mark, at their home in Brooklyn Park, a suburb of Minneapolis city, early on Saturday.

Boelter is also accused of shooting and wounding Senator John Hoffman and his wife, Yvette, at their home about 15km (9 miles) away in the nearby town of Champlin.

The FBI issued a reward of up to $50,000 for information leading to his arrest and conviction.
