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.

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.

Vance Boelter charges: AK-47s, body armor and badge found at Hortman murder scene originally appeared on Bring Me The News.

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.
