BROOKLYN PARK, Minn. (AP) — Police have recovered writings that mentioned the names of multiple lawmakers and other officials in the fake police car they believe a suspect used in the shooting of two legislators in Minnesota.

Brooklyn Park Police Chief Mark Bruley said that the writings that were recovered identified many lawmakers and other officials. The writings were discovered when officers searched a phony police car they believe the suspect used.

Melissa Hortman, a former Minnesota House Speaker, and her spouse were shot and killed early Saturday in their Brooklyn Park home. A second state lawmaker, Sen. John Hoffman and his wife, were shot multiple times in Champlin. Officials say both Hortman and Hoffman were mentioned in the suspect’s writings.

“When we did a search of the vehicle, there was a manifesto that identified many lawmakers and other officials. We immediately made alerts to the state. We took action on alerting them and providing security where necessary,” said Bruley.

Authorities were actively searching for a suspect in the hours following the shootings.

Gov. Tim Walz said Hortman and Hoffman were deliberately targeted.

“We must all, in Minnesota and across the country, stand against all forms of political violence,” Walz said at a press conference Saturday. “Those responsible for this will be held accountable.”

Hoffman, a Democrat, was first elected in 2012. He previously served as vice chair of the Anoka Hennepin School Board, which manages the largest school district in Minnesota. Hoffman and his wife have one daughter. He represents a district north of Minneapolis.

At the time of her death, Hortman was the top Democratic leader in the state Legislature. She was also a former House speaker. She was first elected in 2004. She and her husband had two children.

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.

President Donald Trump said in a White House statement that the FBI would join in the investigation.

“Our Attorney General, Pam Bondi, and the FBI, are investigating the situation, and they will be prosecuting anyone involved to the fullest extent of the law. Such horrific violence will not be tolerated in the United States of America. God Bless the great people of Minnesota, a truly great place!”

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.
