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.

Vance Boelter was captured in a wooded area on Sunday night, and charged in the shootings of two state lawmakers and their spouses. He appeared in federal court after being charged with murder.
