Accused Minnesota assassin Vance Boelter's alleged plan to kill more politicians on his target list was foiled by a police sergeant's proactive hunch, and his capture came after he made a big misstep that exposed his whereabouts to an eagle-eyed neighbor, authorities said.

Vance Boelter charged with murder of Minnesota Rep. Hortman and her husband, and shooting Sen. Hoffman and wife.

Republican Sen. Mike Lee of Utah and others posted unfounded claims on social media about the political affiliation of the gunman arrested in the June 14 fatal shootings of a Democratic Minnesota lawmaker and her husband and the wounding of another Democratic state lawmaker and his wife.

A candlelight light vigil will be held in remembrance of State Rep. Melissa Hortman and her husband, Mark, in St. Paul on Wednesday. The vigil is scheduled for Wednesday from 8 p.m. to 9:30 p.m. on the steps of the State Capitol, the Minnesota House of Representatives announced.

He wounded Sen. John Hoffman and his wife but didn’t come into contact with the two other DFL legislators, investigators say.

Gov. Tim Walz called the event a “politically motivated assassination," with the attack marking the latest such incident over the last several years.

Just hours after House DFL Leader Melissa Hortman and her husband were killed and state Sen. John Hoffman and his wife were wounded, top MAGA voices used those revelations to inaccurately paint Boelter as a Democrat.

Early Saturday morning, when a man dressed like a police officer knocked at the home of a Minnesota state legislator, marked the start of nearly 40 hours of violence and fear that swept through towns in an arc around Minneapolis.
