Accused Minnesota assassin Vance Boelter's alleged plan to kill more politicians on his target list was foiled by a police sergeant's proactive hunch.

St. Cloud State graduate Vance Boelter appeared in federal court Monday afternoon. He is assigned a public defender, citing financial woes.

Boelter was arrested in a field located in a rural part of Sibley County, in southwest Minneapolis, and he was being interviewed at a law enforcement facility, Drew Evans, the superintendent of the state’s Bureau of Criminal Apprehension, said.

Budzinski said her name was included in notes left behind by Vance Boelter, the man charged with killing a Minnesota lawmaker and injuring another.

Suspect's vehicle found in Sibley County as search intensifies for Vance Luther Boelter, wanted in connection with fatal shooting of Minnesota lawmakers in targeted attack.

A cryptic message sent to roommates is just one of many unanswered questions surrounding the suspect who remains at large.

The suspect built a scattered career ranging from food to retailing to private security to pastoring, public records and his online postings show.

The suspect accused of assassinating a Minnesota lawmaker and shooting another this weekend drove to the homes of at least four state politicians as part of a carefully planned attack, federal authorities said on Monday.
