NEW YORK — Luigi Mangione pleaded guilty in a Manhattan federal court on Friday to two federal felony stalking charges resulting in the death of UnitedHealthcare CEO Brian Thompson, openly admitting in sworn courtroom testimony that he tracked and killed the health insurance executive.
The 28-year-old entered an “open plea” without negotiating a formal plea deal or receiving sentencing concessions from prosecutors. When addressing U.S. District Judge Margaret Garnett, Mangione acknowledged his actions directly: “I shot Mr. Thompson in Manhattan and he died. I understood that my actions would place him in fear of death or serious bodily injury. I knew what I was doing was illegal.”
What Happened to Brian Thompson?
Brian Thompson, 50, served as the chief executive officer of UnitedHealthcare, the insurance arm of parent company UnitedHealth Group. On the morning of December 4, 2024, Thompson was ambushed outside the New York Hilton Midtown hotel, where he was scheduled to attend the company’s annual investor conference.
The gunman fled through Central Park before leaving New York City. Following an extensive five-day multi-state manhunt, police arrested Mangione on December 9, 2024, at a McDonald’s restaurant in Altoona, Pennsylvania. Investigators recovered a 3D-printed firearm equipped with a silencer, fake identification documents, and handwritten notes referencing grievances against corporate healthcare insurers.
Federal Plea and State Legal Proceedings
Friday’s courtroom proceedings mark a decisive legal turning point across two parallel jurisdictions:
-
Federal Plea: Mangione pleaded guilty to interstate stalking resulting in death and stalking through interstate facilities. Each count carries a statutory maximum penalty of life imprisonment without parole.
-
Sentencing Date: Judge Garnett scheduled the federal sentencing hearing for December 18, 2026.
-
State Double Jeopardy Fight: Following the federal plea, Mangione’s defense filed motions to dismiss a separate New York state second-degree murder indictment on double jeopardy grounds, arguing he should not face dual trials for the same conduct. The Manhattan District Attorney’s Office confirmed it will contest the motion to maintain the state trial.
Statements from Officials and the Thompson Family
Following the plea entry, Brian Thompson’s family released a public statement expressing gratitude toward the federal justice system for holding the defendant accountable, noting that the plea marks an important step toward legal closure.
New York Police Commissioner Jessica Tisch emphasized outside the courthouse that violence cannot serve as a legitimate tool for social or policy debate. U.S. Attorney prosecutors confirmed that the federal government will formally seek the statutory maximum penalty of life imprisonment at the December 18 sentencing.
