Vance Boelter, 57, has been charged in the shootings of two Minnesota lawmakers and their spouses. The Hennepin County Attorney said Monday that her office intends to pursue first-degree murder charges against him as well.

Authorities arrested and charged Vance Boelter on Sunday night after he allegedly shot and killed House Democratic leader Melissa Hortman and her husband in their Brooklyn Park home and shot and seriously injured state Sen.

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

Hennepin County's chief prosecutor, Mary Moriarty, said at a news conference on Monday (June 16) that her office would seek first-degree murder charges against Vance Boelter, a man accused of killing a Democratic state lawmaker while posing as a police officer.

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.
