Luigi Mangione pleaded guilty on Friday to federal stalking charges in the killing of UnitedHealthcare CEO Brian Thompson and admitted that he shot the executive outside an investor conference in late 2024.
Mangione, 28, read a statement in court in which he described tracking Thompson, 50, to the conference in
Midtown Manhattan and shooting him with a 3D-printed gun equipped with a silencer.
Mangione had previously said he was not guilty of the state and federal charges against him in connection with Thompson’s killing. He is scheduled to stand trial next month on state murder charges.
Mangione faces a maximum of life in prison on the federal stalking charges. A sentencing hearing is scheduled for December.
The killing of a prominent corporate executive in broad daylight, combined with Mangione’s grievances against what he called the “greed-fuelled” health insurance industry, have made the case a focus of intense public interest.
Some view Mangione as a symbol of their anger with health insurance providers. Supporters wearing “Free Luigi” T-shirts have attended hearings in his case, and his story has generated memes, merchandise, even a musical.
Outside the courthouse on Friday, Jamie McDonald, the US attorney for the Southern District of New York, had strong words for those inclined to support Mangione.
McDonald said: “Any person who celebrates, encourages or excuses actions like these is fundamentally wrong. Violence is not a legitimate instrument to promote any political or social message.”
In a statement, Thompson’s family said that Friday’s guilty plea was an important step toward justice.
A family statement said: “While nothing will ease the pain of losing him, we are grateful that the federal justice system has held the person responsible for this heinous act accountable.”
The family urged the court to “ensure that sentencing reflects the severity of this crime”.
Karen Friedman Agnifilo, Mangione’s lawyer, said Mangione had endured “years of debilitating pain” after breaking his back and had struggled to navigate the health insurance system.
Mangione “believed that the system had failed him and destroyed his life”, Friedman Agnifilo said. She accused prosecutors of trying to punish Mangione twice by launching both federal and state cases against him and said his legal team filed a motion on Friday seeking the dismissal of the state case.
Mangione’s state trial on murder and weapons charges is set to start on September 8. But under New York’s double-jeopardy statute, state prosecutors are restricted from pursuing cases if a defendant has already been convicted of a similar offence.
Because Mangione has pleaded guilty to federal charges, there is a “very good chance that double jeopardy will apply with respect to his state case”, according to Anna Cominsky, a professor at New York Law School.
