BROOKLYN PARK, Minn, June 15, (AP): A massive search was stretching into its second day for a man who authorities say posed as a police officer and fatally shot a Democratic state lawmaker in her suburban Minneapolis home, an act Gov Tim Walz called "a politically motivated assassination.” Authorities said the suspect also shot and wounded a second lawmaker and was trying to flee the area.

Former House Speaker Melissa Hortman and her husband, Mark, were killed in their Brooklyn Park home early Saturday. Sen. John Hoffman, also a Democrat, and his wife, Yvette, were injured at their Champlin address, about 9 miles (about 15 kilometers) away. Authorities identified the suspect as 57-year-old Vance Boelter, and the FBI issued a reward of up to $50,000 for information leading to his arrest and conviction.

They shared a photo taken Saturday of Boelter wearing a tan cowboy hat and asked the public to report sightings. Hundreds of law enforcement officers fanned out in the search for the suspect. Authorities had not given any details on a possible motive as of Saturday night. Boelter is a former political appointee who served on the same state workforce development board as Hoffman, records show, though it was not clear if or how well they knew each other.

The attacks prompted warnings to other state elected officials and the cancellation of planned "No Kings” demonstrations against President Donald Trump, though some went ahead anyway. Authorities said the suspect had "No Kings” flyers in his car and writings mentioning the names of the victims as well as other lawmakers and officials, though they could not say if he had any other specific targets.

A Minnesota official told AP the suspect’s writings also contained information targeting prominent lawmakers who have been outspoken in favor of abortion rights. The official spoke on the condition of anonymity because the investigation was ongoing. Law enforcement agents recovered several AK-style firearms from the suspect’s vehicle, and he was believed to still be armed with a pistol, a person familiar with the matter told AP. The person could not publicly discuss details of the investigation and spoke on condition of anonymity.
