One of three prosecutions
United States v. Mangione
United States v. Mangione is the federal prosecution of Luigi Mangione over the December 2024 killing of UnitedHealthcare chief executive Brian Thompson in Manhattan. The U.S. Attorney for the Southern District of New York announced the charges on December 19, 2024, and the case was assigned to Judge Margaret M. Garnett. At a June 29, 2026 conference, the court adjourned the trial to January 2027.
Case at a glance
In two opinions issued January 30, 2026, the court dismissed the two counts that had carried death-penalty eligibility, holding that stalking is not a "crime of violence" under the statute, and declined to suppress the backpack evidence from the Altoona arrest.
The government told the court on February 27, 2026 that it would not appeal the dismissal, and a March 3, 2026 order noted the case was no longer capital. The counts that went forward carried a maximum of life in prison without parole.
At the June 29, 2026 conference, Judge Margaret M. Garnett set jury selection to begin January 5, 2027, with opening statements January 25, 2027, and entered a pretrial schedule running through December 2026.
