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 Thompsonâs 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 Mangioneâs grievances against what he called the âgreed-fuelledâ 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 âFree Luigiâ 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: âAny 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.â
In a statement, Thompsonâs family said that Fridayâs guilty plea was an important step toward justice.
A family statement said: âWhile 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.â
The family urged the court to âensure that sentencing reflects the severity of this crimeâ.
Karen Friedman Agnifilo, Mangioneâs lawyer, said Mangione had endured âyears of debilitating painâ after breaking his back and had struggled to navigate the health insurance system.
Mangione âbelieved that the system had failed him and destroyed his lifeâ, 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.
Mangioneâs state trial on murder and weapons charges is set to start on September 8. But under New Yorkâs 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 âvery good chance that double jeopardy will apply with respect to his state caseâ, according to Anna Cominsky, a professor at New York Law School.
