Authorities are continuing to search for a suspect who dressed as a police officer, exchanged gunfire with officers and fled, officials said at a Saturday morning news conference.

State Rep. Melissa Hortman and her husband were shot and killed and State Sen. John Hoffman and his wife Yvette were shot and wounded in “targeted shootings” in Champlin and Brooklyn Park, two neighboring suburban cities 10 to 20 miles outside Minneapolis.

Hortman served the people of Minnesota with compassion and grace, Walz said.

“She woke up every day determined to make this state a better place.” he said.

Walz said early Saturday morning he was briefed on “targeted shootings” and had activated the State Emergency Operations Center in response.

The Brooklyn Park Police Department issued an early morning shelter-in-place alert for a 3-mile radius around the Edinburgh Golf Course, the city of Brooklyn Park said in a post to Facebook. According to local news outlets KARE 11 and Fox 9, the alert warned the public that a suspect could be posing as law enforcement.

Hoffman and Hortman are both members of the Minnesota Democratic-Farmer-Labor Party. Hoffman, 60, and his wife Yvette have one child and live in Champlin, according to his lawmaker profile. He was first elected in 2012. Hortman and her husband Mark have two children and live in Brooklyn Park, according to her profile. She was elected in 2004.

“I cannot emphasize enough that this is not ok. Any type of violence against elected officials is not ok. Any type of violence against other people is not ok,” nearby Mounds View Mayor Zach Lindstrom said in a post.
