Vance Boelter, an alleged political assassin, reportedly sent a frantic confession letter to FBI Director Kash Patel, in which he claimed that Governor Tim Walz had encouraged him to assassinate Democratic lawmakers as part of a sinister scheme.

The erratic handwritten notes were made public on Tuesday, coinciding with Boelter’s indictment for the alleged shooting of former Democratic House Speaker Melissa Hortman and her husband, Mark, at their Minneapolis residence on June 14.

“Dear Kash Patel. My name is Dr. Vance Luther, Boelter E.d.D. I am the shooter at large in Minnesota,” Boelter allegedly wrote.

Within his correspondence, Boelter asserted that he had been “recruited by US military personnel for covert operations” since his college years, claiming involvement in “duty-bound” missions internationally.

“Recently, I was approached about a project that Tim Walz wanted done… Tim wanted me to kill Amy Klobuchar and Tina Smith. Tim wants to be a senator,” he claimed, referring to the Minnesota US senators.

Elsewhere in the ramblings, he alleged: “I told Tim I want nothing to do with it and if he didn’t call off that plan I would go public.”

The note, which was first reported on last month in the wake of his arrest, was found in his abandoned SUV at the crime scene after he allegedly gunned down Hortman and her husband.

Boelter allegedly shot state Senator John Hoffman and his wife Yvette earlier that night but they miraculously survived.

The letter didn’t disclose why Boelter allegedly targeted the two couples.

He insisted to The Post last week that the murders had nothing to do with President Trump or abortion — but stopped short of saying what allegedly drove him to kill.

“There is little evidence showing why he turned to political violence and extremism,” acting U.S. Attorney Joseph Thompson said following his indictment.

“What he left were lists: politicians in Minnesota, lists of politicians in other states, lists of names of attorneys at national law firms.”

Asked for comment on the letter, a spokesman for Walz told the Washington Post, “The tragedy continues to be deeply disturbing for all Minnesotans.”
