(Radio Iowa) – The suspect in the shootings of two Minnesota lawmakers and their spouses and the murder of one of those couples is in custody. Fifty-seven-year-old Vance Boelter — the subject of a 43-hour-long manhunt, was arrested near his home in Green Isle, Minnesota. It’s about 120 miles north of the Iowa border. Lieutenant Colonel Jeremy Geiger of the Minnesota State Patrol spoke during a news conference late Sunday night.

“The suspect crawled to law enforcement teams and was placed under arrest at that point in time.” Drew Evans, Superintendent of Minnesota’s Bureau of Criminal Apprehension, says SWAT teams had surrounded Boelter in a field in southern Minnesota.”The incredible teamwork that was done and the large number of law enforcement certainly put us in a position where they were able to maneuver into this area to safely put him in a place where, you know, I don’t know what was going on in his head and I wouldn’t speculate,” Evans said, “but they have incredibly professional teams that are trained on this on how to take somebody into custody and they provided the commands and he gave up peacefully.”

Evans says Boelter was armed at the time of his arrest. Mark Bruley  is the police chief in Brooklyn Park, the Minneapolis suburb where the former speaker of the Minnesota House and her husband were murdered. “There’s no question that this was the largest manhunt in state history,” he said. “Just down at the scene where he was taken into custody there were 20 different SWAT teams over an extremely large area hunting this individual down to take him into custody.”

Minnesota officials say their investigation will continue to expand, as they compile evidence for state and perhaps federal trials. They’re also investigating whether anyone provided help to the suspect who was arrested about 60 miles from the Minneapolis suburbs where the shootings happened.

Iowa elected officials from both political parties have used words like horrible, horrendous and heartbreaking to describe the shootings. The governor, Senator Grassley and other lawmakers all said political violence is unacceptable.
