Luigi Mangione pleaded guilty in a New York federal courtroom on Friday to charges related to the December 2024 killing of UnitedHealthcare CEO Brian Thompson. During the hearing, the 28-year-old defendant admitted to shooting Thompson outside a Manhattan hotel where the company was holding an annual conference. The admission follows more than a year and a half of legal proceedings and intense public attention.
The hearing, presided over by Judge Margaret Garnett, was attended by members of Thompson’s family, the press, and observers. Mangione, wearing a beige prison uniform and foot shackles, conferred with his attorney, Karen Friedman Agnifilo, before changing his plea from not guilty to guilty. The court heard Mangione describe how he planned and executed the shooting, citing his personal history with the healthcare insurance industry as a motivating factor.
Mangione told the court he suffered from "severe pains from a broken back" and spent years dealing with insurance companies. He testified that he researched UnitedHealthcare’s annual conference online and contacted the company under the guise of an investor to obtain details about the event. He also admitted to manufacturing the firearm used in the shooting with a 3D printer. Mangione stated that on the morning of December 4, 2024, he shot Thompson in Manhattan, resulting in the executive's death.
For the family of Brian Thompson, the admission of guilt represents a significant step in the legal process following the December 2024 shooting. The outcome of this federal case sets a precedent for how violent crimes against corporate executives involving interstate stalking and 3D-printed firearms are prosecuted at the federal level. The plea also clarifies the specific actions taken by Mangione, including his method of obtaining information about the victim and the manufacturing of the weapon, which had been subjects of investigation for over 18 months.
The legal proceedings for Mangione are not yet concluded. While the federal judge has accepted the guilty plea, Mangione is still scheduled to face separate state charges in a trial beginning in September. The federal sentencing is scheduled for December 18. Until that date, Mangione will remain in custody. The state-level trial will determine additional penalties and legal consequences for the killing of Thompson, independent of the federal stalking charges addressed on Friday.
