The man suspected of shooting two legislators and their spouses in Twin Cities was in custody Sunday night after an intense manhunt.

More than 100 officers and numerous SWAT teams searched throughout the day and into the night in Sibley County.

Minnesota House of Representatives Speaker Lisa Demuth said in a Sunday night statement: “I’m grateful that this nightmare has come to an end with the suspected murderer captured alive so he can be charged, prosecuted, and punished for the horror he has wrought on our state.”

A nationwide warrant had been issued for two murders and two attempted murders, and there is a federal warrant for unlawful flight to avoid prosecution, said Minnesota Bureau of Criminal Apprehension Superintendent Drew Evans.

Officials announced on Saturday that Vance L. Boelter, 57, is the suspect in the 3:35 a.m. Saturday shootings that killed Minnesota Rep. Melissa Hortman and her husband at their Brooklyn Park home, and shootings that injured Minnesota Sen. John Hoffman and his wife at their Champlin house about 2 a.m.

Evans also clarified Sunday about what authorities called a “manifesto” Saturday. He said what was found in a vehicle that Boelter left behind at a shooting was a notebook with “a lot of lawmakers and others” listed. He said it was not a “treatise on all kinds of ideology.”

Law enforcement has no indication that Boelter “did anything other than conduct these acts by himself,” Evans said. “But that doesn’t mean we aren’t exploring more fully if there’s any other threats that might be there. We will continue to evaluate that.”

Sibley County search

Boelter and his wife, Jenny Boelter, own a home in Green Isle, Minn., in Sibley County, which is about an hour’s drive southwest of the Twin Cities.

An abandoned vehicle was found about eight miles from the house Sunday morning, leading law enforcement to search the area. Authorities had been looking for the vehicle since Saturday, Evans said.

Boelter was seen on surveillance video in Minneapolis in the hours after the shooting and was wearing a cowboy hat. “A hat that we believe he was wearing was found in proximity to that vehicle, which is what has led us to believing he was in that area,” Evans said.

An emergency alert in Sibley County said the vehicle was found near Minnesota Highway 25 and 301st Avenue in Faxon Township.

“Keep your doors locked and vehicles secured,” the alert continued. “Report suspicious activity to 911.” It also said law enforcement would be going to residences in the area to ask to search properties.

Search teams in the area “will continue to be active until they feel that they have done a thorough and complete search,” Evans said late Sunday afternoon. Law enforcement found evidence in the car that is “relevant to this investigation,” Evans added.

Gov. Tim Walz and law enforcement officials were planning to give an update to the media at 10:30 p.m. Sunday.

Search for answers in ‘complex situation’

Authorities have been in contact with the victims’ families, “trying to provide some answers,” Evans said.

“I would encourage everybody online and in our communities to not speculate on what occurred and what the motivation was for this,” he continued. “We often want easy answers for complex problems, and this is a complex situation that our investigators are going to need time to sift through the information and evidence, and those answers will come as we complete the full picture of our investigation.”

Evans said a BCA tipline had received more than 400 tips.

Law enforcement “haven’t seen specific individuals” assisting Boelter as he evades law enforcement, Evans said. “He’s certainly been in contact with individuals, whether or not they’re providing active assistance, I can’t provide that.”

The FBI is offering a $50,000 reward for information leading to the arrest and conviction of Boelter.

ATF: Suspect fled Saturday when officers were helping victims

After John and Yvonne Hoffman were shot early Saturday, police said they went to check on the Hortman home and spotted what appeared to be a police SUV with emergency lights in the driveway. Officials say the suspect was impersonating an officer and exchanged gunfire with police.

The suspect retreated into the Hortman home and escaped on foot out a back door, leaving the vehicle behind in the driveway.

“Only a couple of officers” initially went to the house, so they didn’t have it surrounded, Travis Riddle, special agent in charge of the Bureau of Alcohol, Tobacco, Firearms and Explosives’ St. Paul field division, said Sunday morning on Fox News.

“While they were seeking cover and also trying to render aid to victims, the suspect was able to flee from the residence undetected,” Riddle said.

Identification found at the scene “helped us ID the suspect” and the ATF’s tracing system on recovered firearms also confirmed the identity of the suspect, Riddle said.

Boelter is listed as director of security patrols for Praetorian Guard Security Services in Minnesota. Jenny Boelter is named as president and CEO on the site.

Riddle said he thinks the suspect “got lucky” in getting away Saturday. “I don’t believe his tactical expertise would have surpassed the law enforcement response,” he said.

An official told the Associated Press that the suspect’s writings contained information targeting prominent Democratic lawmakers who have been outspoken in favor of abortion rights. A federal law enforcement official told the New York Times that the list included about 70 potential targets, including politicians, doctors, community and business leaders, and locations for Planned Parenthood and other health care centers. Some were in other states, including Wisconsin.

Law enforcement has not located evidence that Boelter made prior threats, Evans said Sunday. “That will obviously be part a deeper dive to really understand the motivation of this individual,” he added.

Wife pulled over Saturday

On Saturday, law enforcement pulled over Boelter’s wife during a traffic stop in Mille Lacs County, Minn., according to the sheriff in that county. She is not in custody.

“Anytime an individual is identified as a suspect in investigation, we’re going to talk to their family members,” Evans said. He said they not only talked to Boelter’s wife, but also other family members “to really understand what’s going on.” They were cooperative with law enforcement.

Mille Lacs County sheriff’s deputies assisted law enforcement from Hennepin County with a traffic stop between 10:30 and 11 a.m. Saturday near a convenience store in Onamia, said Sheriff Kyle Burton. Staff who responded told Burton that the shooting suspect’s wife was in the vehicle, along with several other relatives.

Jenny Boelter did not respond to a Sunday morning message from the Pioneer Press. Onamia is about 125 miles north of the couple’s home.
