Minnesota lawmaker shooting suspect Vance Luther Boelter, 57, is expected to face federal charges after officials captured him in Sibley County on Sunday night in what police described as the “largest manhunt” in the state’s history.

In addition to the potential federal charges, the Hennepin County Attorney’s Office on Monday announced that it intends to file first-degree murder charges against Boelter, who is accused of killing former Minnesota House Speaker Melissa Hortman and her husband, Mark, early Saturday morning at their Brooklyn Park home in Minneapolis. 

He also allegedly shot State Sen. John Hoffman, also a Democrat, and his wife, Yvette, in their nearby Champlin home in a related attack. 

Boelter is currently charged with two counts of second-degree murder for the deaths of Victims 1 and 2 — identified as Melissa and Mark Hortman — and two counts of attempted second-degree murder for the shootings of Victims 3 and 4 — identified as John Hoffman and Yvette Hoffman.

His bail was set at $5 million. 

Authorities have said the suspect targeted lawmakers in a planned attack, showing up at their homes wearing a police-like uniform and a mask.

Democratic Minnesota Sen. Amy Klobuchar shared a message from Hoffman’s wife on Sunday, saying the state senator was shot nine times and she eight.

“John is enduring many surgeries right now and is closer every hour to being out of the woods,” Yvette wrote. “He took [nine] bullet hits. I took [eight] and we are both incredibly lucky to be alive. We are gutted and devastated by the loss of Melissa and Mark. There is never a place for this kind of political hate.”
