The home of Minnesota Democratic Rep. Melissa Hortman, who was fatally shot in a targeted attack at their home in Brooklyn Park over the weekend, was broken into on Tuesday night, though a preliminary investigation found nothing appeared to be missing.

FOX 9 in Minneapolis reported that the Brooklyn Park Police Department launched an investigation into the overnight break-in after being alerted about the incident at about 8 a.m. on Wednesday morning.

A preliminary investigation found the person allegedly entered the back of the home after removing a piece of plywood covering a window, then breaking the window.

Although the house showed evidence it had been searched, the station reported, family members told police it did not appear anything was missing.

Hortman and her husband were shot and killed on Saturday morning, as were State Sen. John Hoffman, also a Democrat, and his wife, Yvette, in their nearby Champlin home.

Vance Luther Boelter, 57, has since been charged with killing all four victims.

U.S. Attorney Joseph H. Thompson said Monday that Boelter’s primary motive was “to go out and murder people” as authorities announced the suspect’s capture on Monday after a two-day manhunt. 

Boelter now faces federal charges after officials arrested him in Sibley County on Sunday night. He is charged with two counts of stalking, two counts of murder and two counts of firearm-related crimes. Boelter is also facing second-degree murder charges filed in Hennepin County.
