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.

The suspect is accused of fatally shooting Minnesota state Rep. Melissa Hortman and her husband, Mark, at their home. He also shot Minnesota state Sen. John Hoffman and his wife, Yvette, at their home — but they survived the attack.

The FBI revealed during a separate conference Monday morning that Boelter had gone to the homes of two other Minnesota lawmakers the night he killed Rep. Melissa Hortman and her husband and injured Sen.
