The FBI has released photos of a man who law enforcement says posed as a police officer and fatally shot a Minnesota politician in her home in what the state governor called “a politically motivated assassination.”

Hundreds of police officers have fanned out across a Minneapolis suburb in pursuit of the suspect. Authorities said the same man also shot and wounded a second lawmaker and was believed to be trying to flee the area.

Former House Speaker Melissa Hortman and her husband, Mark, where killed in their Brooklyn Park home. Senator John Hoffman, also a Democrat, and his wife, Yvette, were injured at their Champlin address, about 15 kilometres away.

Authorities identified the suspect as 57-year-old Vance Boelter, and the FBI issued a reward of up to US$50,000 for details leading to his arrest and conviction.

Authorities displayed a photo of Boelter wearing a tan cowboy hat and asked the public to report sightings.

Another photo of the suspect appeared to show him impersonating a police officer in a realistic latex mask, ABC news reports, citing law enforcement sources.

Drew Evans, superintendent of the Minnesota Bureau of Criminal Apprehension, said investigators obtained video as well.

He did not give details on a possible motive.

Boelter is a former political appointee who served on the same state workforce development board as Melissa hortman, the former House Speaker who was killed, according to state records.

Hortman, 54, served in the Minnesota House of Representatives since 2005. She briefly relinquished her speakership earlier this year during a three-week walkout in a power struggle with Republicans. Under a power-sharing agreement, she turned the gavel over to the top Republican, Rep Lisa Demuth, and assumed the title speaker emerita.

Gov. Walz described her as a “formidable public servant, a fixture and a giant in Minnesota every day, steadfast to make this state a better place.”

“She is irreplaceable,” he said.

Hortman and her husband had two adult children.

Hoffman, 60, was first elected in 2012 and played a key role as chair of the Senate Human Services Committee, wich oversees one of the biggest parts of the state budget.

He and his wife have one daughter.

State patrol Col Christina Bogojevic asked people “out of an abundance of caution” not to attend any of the “No Kings” protests that were scheduled for across the state on Saturday.

Bogojevic said authorities didn’t have any direct evidence that the protests would be targeted, but said the suspect had some “No Kings” flyers in their car.

Organisers announced that all of the protests across the state were cancelled.

The Suspect

“She is irreplaceable.”

Boelter was appointed to the workforce development board by then-Minnesota Governor Mark Dayton in 2016 and then reappointed in 2019 by the current governor to a four-year term that expired in 2023, state records show.

state corporate records show Boelter’s wife filed to create a company called Praetorian Guard Security Services LLC with the same Green Isle mailing address listed for the couple. On a website for the business, Boelter’s wife is listed as the president and CEO while he is listed as the director of security patrols.

The company’s homepage says it provides armed security for property and events and features a photo of an SUV painted in a two-tone black and silver pattern similar to a police vehicle, with a light bar across the roof and “praetorian” painted across the doors.

Another photo shows a man in black tactical gear with a military-style helmet and a ballistic vest with the company’s name across the front.

An online resume says he is a security contractor who has worked oversees in the Middle East and Africa, in addition to past managerial roles at companies in Minnesota.

Massive Search Effort Underway

Hours after the shootings, hundreds of police and sheriff deputies from departments in the region, some in tactical gear with assault-style weapons were scattered through the town.

An alert sent to people’s cellphones asked residents to continue sheltering in place as police were still looking for a suspect “who is armed and dangerous.”

“Suspect is white male, brown hair, wearing black body armor over blue shirt and blue pants and may misrepresent himself as law enforcement. Do not approach. Call 911,” the alert said.

Some roadblocks had been set up in which authorities stopped and checked vehicles.

“this is crazy, someone going after representatives. This is wrong. I’m hoping they’ll catch them,” said Brooklyn Park resident Douglas Thompson, 62, adding he wasn’t worried and believed authorities would catch the suspect.

Minnesota House Speaker Lisa Demuth, a Republican from Cold Spring, called the attack “evil” and said she was “heartbroken beyond words” by the killings of Hortman and her husband, Mark.

“With the law enforcement response ongoing and details still emerging, I will simply ask all Minnesotans to please lift up in prayer the victims of this horrific attack, as well as the law enforcement personnel still working to apprehend the perpetrator,” Demuth said in a statement.

Political Violence

The shootings are the latest in a series of violent attacks against lawmakers across parties in recent years.

In april, a suspect set fire to the home of Democratic Pennsylvania Gov. Josh Shapiro, forcing him and his family to flee the building during the Jewish holiday of Passover.

The suspect told law enforcement that he planned to beat Shapiro with a small sledgehammer if he found him, according to court documents.

In July 2024, the republican Trump was grazed on the ear by one of a hail of bullets that killed a Trump supporter. Two months later, a man with a rifle was discovered in some shrubbery near the president’s golf course in Florida and arrested by Secret Service agents.

Other high-profile attacks in recent years have included a 2022 hammer attack on the husband of then-House Speaker Nancy Pelosi inside their San Francisco home, and a 2020 plot by anti-government extremists to kidnap Democratic Governor Gretchen Whitmer at her vacation home and start a civil war.

Senate Democratic Leader Chuck Schumer said Saturday that he has asked Capitol Police to “promptly increase security” for Minnesota Senators Amy Klobuchar and Tina Smith, both Democrats.

Schumer said he had also asked Senate Majority Leader John Thune, a Republican from South Dakota, to hold a briefing for senators on member security.

“Condemning violence is important but it is not enough,” Schumer said in a post on X.

“We must also confront the toxic forces radicalising individuals and we must do more to protect one another, our democracy, and the values that bind us as Americans.”
