THE gunman accused of killing a Democratic politician and her husband penned a chilling letter to the FBI where he seemingly admitted that he carried out the murders.

Vance Boelter was indicted on murder and stalking charges – weeks after Minnesota politician Melissa Hortman and her husband were found dead in their home.

An arraignment hearing is set to take place in September and Boelter is expected to stand trial in November.

As part of investigators probe into the shootings, a letter addressed to Kash Patel, the director of the FBI, was found in Boelter’s car.

This was unsealed as part of the indictment.

In the chilling note, Boelter, 57, described himself as the shooter at large.

“I will probably be dead by the time you read this letter,” the note said.

He then started to discuss a so-called project and claimed Tim Walz, who was Kamala Harris’ running mate in last year’s presidential election, wanted it carried out.

There is no evidence to suggest Walz had any connection with the project.

In the note to Patel, Boelter claimed Walz had instructed him to kill Democratic senators Amy Klobuchar and Tina Smith.

Klobuchar dined with Hortman just hours before she was killed, as reported by Politico.

He went on to explain that it was part of a plot for Walz to be awarded a senate seat.

“I told Tim I wanted nothing to do with it,” Boelter claimed.

Boelter claimed that his family’s well being would have been put at risk if he didn’t go through with it.

“If you want me to turn myself in, it need to be directly to you,” he begged.

He said he was willing to be holed up in a military prison outside of the US.

“I am willing to spill all the beans,” Boelter wrote as he concluded his letter.

“I just want my family safe. They had nothing to do with this and are totally innocent.

“This was a one person job.”

Minnesota prosecutors have described the deaths of Hortman and her husband, Mark, as “targeted political assassinations.”

Joseph Thompson, an acting US attorney, described Boelter’s actions as “heinous.”

“Vance Boelter planned and carried out a night of terror that shook Minnesota to its core,” he said.

Boelter is said to have posed as a fake cop before carrying out the killings.

Before allegedly killing Hortman, Boelter drove to state senator John Hoffman’s home.

He arrived at the property at around 2am on June 14 in what was a fake cop car.

The vehicle had a license plate that stated “police” and was had blue lights bolted on the top of it.

A masked Boelter trooped up to the property and demanded the politician to open the door.

Boelter claimed there had been a shooting in the area, but Hoffman and his wife Yvette realize he is a phony police officer.

The gunman is accused of shooting Hoffman and Yvette several times.

Around 20 minutes later, Boelter then headed to another lawmaker’s home but no one was in the property.

At around 3:30am, Boelter then turned up at Hortman’s home.

But, local cops were dispatched to the property to carry out a welfare check.

Boelter starts shooting at the cops before fatally wounding the politician and Mark.

Investigators searched the Hortman family home and a Beretta gun was left behind as was the mask Boelter was wearing.
