BROOKLYN PARK, Minn. – Minnesota Governor Tim Walz announced that former state House Speaker Melissa Hortman and her husband were victims of a politically motivated assassination. Additionally, another lawmaker and his wife were injured by gunfire. Authorities were on the hunt for a suspect following these deliberate attacks.

“Political violence has no place in Minnesota or anywhere in the nation,” Gov. Walz declared during a press conference on Saturday. “Those accountable for this act will face justice.”

The injured lawmaker was identified as state Senator John Hoffman, a Democrat who first took office in 2012. Prior to his tenure in the state Senate, he held the position of vice chair on the Anoka Hennepin School Board, overseeing Minnesota’s largest school district.

Hoffman is married and has one daughter. Hortman was the top House Democratic leader in the state Legislature and a former House speaker. She was first elected in 2004.

Drew Evans, superintendent of the Bureau of Criminal Apprehension, said that authorities were actively searching for a suspect.

Autopsies will be done to determine extent of injuries, but Hortman and her spouse died from gunshot wounds, Evans said. A “shelter in place” order was in effect early Saturday.

Public Safety Commissioner Bob Jacobson said the suspect was posing as a law enforcement officer.

“Suspect exploited the trust of our uniforms, what our uniforms are meant to represent. That betrayal is deeply disturbing to those of us who wear the badge with honor and responsibility,” he said.

Police Chief Mark Bruley said the suspect fled out of the back of Hortman’s house after an exchange of gunfire with police.

The suspect was dressed like a uniformed officer and operating a vehicle that “looked exactly like an SUV squad car. It was equipped with lights, emergency lights and looked exactly like a police vehicle,” Bruley said.

The FBI has joined in the investigation, according to a statement posted by Dan Bonginio, the agency’s deputy director.

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.

The shootings happened at a time when political leaders nationwide have been attacked, harassed and intimidated during a time of deep political divisions.

GIFFORDS, the national gun violence prevention organization led by former U.S. Rep. Gabrielle Giffords, released the following statement.

“My family and I know the horror of a targeted shooting all too well,” Giffords said. “An attack against lawmakers is an attack on American democracy itself. Leaders must speak out and condemn the fomenting violent extremism that threatens everything this country stands for.”

Giffords was shot in the head in 2011 by a gunman who killed six people and injured 12 others. She stepped down from Congress in January 2012 to focus on her recovery.
