Premeditated Attack on Healthcare Executive
Luigi Nicholas Mangione meticulously planned his deadly attack on UnitedHealthcare CEO Brian Thompson for months before gunning him down on a Midtown Manhattan street on December 4, 2024. Federal prosecutors have charged Mangione with murder and interstate stalking resulting in death, each carrying potential life sentences.
Court documents reveal Mangione traveled from out of state to New York City, conducted reconnaissance, and used false identification to check into a hostel before the attack. On the day of the murder, he rode a bicycle to the crime scene and shot Thompson with a 9mm pistol equipped with a silencer in broad daylight.

Manifesto Reveals Political Motives
Red-spiral notebooks recovered by authorities contain Mangione’s manifesto detailing his disdain for the health insurance industry and moral reasoning behind the assassination. His writings reveal he deliberately rejected a mass-casualty bombing, stating “Bombs=terrorism,” and instead opted for a targeted killing he believed would be more morally defensible.

The manifesto criticized the Unabomber Ted Kaczynski for failing to effectively communicate his ideas to the public by “indiscriminately mailbombing innocents.” Mangione wrote that such tactics cause “normies” to “categorize him as an insane serial killer, focus on the act/atrocities themselves, and dismiss his ideas.”
Mangione’s writings claimed the health insurance industry “extracts human life force for money” and calculated that his attack would deliver “a real low blow to the company financials.” He left messages on bullet casings referencing the book “An American Sickness,” further indicating his premeditated intent to send a political message.
Justice Department Response and Legal Proceedings
Acting U.S. Attorney Edward Y. Kim condemned the attack, stating: “Brian Thompson was gunned down in cold blood as he walked down a street in midtown Manhattan. Thompson was allegedly killed just because he held the position of chief executive officer of a health insurance company.”
Mangione’s defense team is challenging the admissibility of his writings and statements, claiming his constitutional rights were violated during his arrest. Pre-trial hearings will determine what evidence can be presented at trial, including the notebooks and statements to police.
The Manhattan District Attorney’s Office has also brought separate charges against Mangione, though he remains presumed innocent until proven guilty.
