New details about Vance Boelter, accused of fatally shooting a state lawmaker and her husband, were revealed in court documents.

Vance Boelter, 57, is accused of killing Minnesota state Rep. Melissa Hortman and her husband, Mark, and wounding state Sen. John Hoffman and his wife, Yvette.

He wounded Sen. John Hoffman and his wife but didn’t come into contact with the two other DFL legislators, investigators say.

Surveillance footage captured an attempted murder, according to charges unsealed Sunday: A man wearing a mask, a blue shirt and police-style tactical vest with a badge knocked on a door in Champlin and announced himself as a police officer. He then entered the house and shot Minnesota Sen. John Hoffman and his wife.
