When the gunman in the shootings of two Minnesota lawmakers approached their homes early on Saturday morning, he was armed with not just a handgun but also a wealth of other gear: a black tactical vest, a badge, a flashlight, a Taser. He arrived in a black S.U.V. with flashing police lights.

The man suspected of killing a Minnesota lawmaker and wounding another crawled to officers in surrender Sunday after they located him in the woods near his home, bringing an end to a massive, nearly two-day search that put the entire state on edge.
