A massive two-day manhunt ended on Sunday with the arrest of Vance Boelter, 57, for allegedly killing a Minnesota Democratic state lawmaker and her husband while posing as a police officer, Governor Tim Walz said.

Residents of Sibley County are encouraged to lock their doors and secure their vehicles, adding that law enforcement will be going to area residences to ask to search properties.

Boelter is wanted for killing State Rep. Melissa Hortman and her husband, as well as wounding State Sen. John Hoffman and his wife.
