Manhunt continues for gunman who 'posed as cop' to kill politician - as texts revealed

A manhunt is continuing after the gunning down of a Democrat politician and her husband - with police saying they're acting on the assumption he is still alive and dangerous.

Melissa Hortman and Mark Hortman were shot dead at home in a Minneapolis suburb on Saturday in what governor Tim Walz called a "politically motivated assassination". Democrat senator John Hoffman and his wife were also shot multiple times at their home nine miles away, but survived.

A search is under way for Vance Boelter, 57, who authorities believe wore a mask as he posed as a police officer, and also used a vehicle resembling a squad car. Several AK-style firearms and a list of about 70 names, which included politicians and abortion rights activists, were found inside.

Boelter was last caught on camera wearing a cowboy hat - a similar hat was found near another vehicle belonging to him on Sunday. Authorities said at their latest news conference they assume he is still alive.

Hundreds of police officers are searching for Boelter, who escaped from the Hortmans' house on foot after an exchange of gunfire. Senator Hoffman was shot nine times and is having multiple surgeries, according to a text message shared on Instagram by fellow senator Amy Klobuchar on Sunday.

The text from Mr Hoffman's wife, Yvette, added: "I took 8 and we are both incredibly lucky to be alive." She said her husband "is closer every hour to being out of the woods". "We believe [Boelter's] somewhere in the vicinity and that they are going to find him," Senator Klobuchar told NBC's Meet the Press.

"Everyone's on edge here," she added, "because we know that this man will kill at a second." Police said they responded to gunfire reports at the Hoffmans' Champlin home shortly after 2am on Saturday and found them with multiple gunshot wounds. They then checked on the Hortmans' home, in the nearby Brooklyn Park suburb, and saw what appeared to be a police car and a man dressed as an officer leaving the front door.

"The individual immediately fired upon the officers, who exchanged gunfire, and the suspect retreated back into the home" and escaped on foot, said Brooklyn Park police chief Mark Bruley.

A cowboy hat similar to the one seen in the police appeal was found nearby. It's been revealed that the suspect texted friends around 6am on Saturday to say he had "made some choices" and was "going to be gone for a while".

According to AP, which has seen the messages, he reportedly said: "May be dead shortly, so I just want to let you know I love you guys both and I wish it hadn't gone this way... I'm sorry for all the trouble this has caused." Records show Boelter - a father of five - is a former political appointee who served on the same state workforce development board as Mr Hoffman.

However, it's unclear to what extent they knew each other, if at all. Mr Hoffman, 60, was first elected in 2012 and runs a consulting firm called Hoffman Strategic Advisors.

Melissa Hortman, a 55-year-old mother of two, was first elected in 2004 and was the top house Democratic leader in the state legislature. She also served as speaker of the Minnesota House of Representatives.

Mrs Hortman used her position to champion protections around abortion rights, including laws to cement Minnesota's status as a safe refuge for people from restrictive states, who travel there for an abortion. Her work also sought to introduce protections for services that provide abortions..
