Luigi Mangione confessed to fatally shooting health insurance executive Brian Thompson in court on Friday and pleaded guilty to two federal charges of stalking the CEO with the intent to kill him. Mangione, dressed in beige prison attire, delivered a prepared statement criticizing the U.S. health insurance system in a composed manner.
Thompson’s widow, accompanied by family members, was present in the gallery when Mangione admitted to the shooting, causing her to become emotional as others comforted her. The guilty plea by Mangione avoids a federal trial in the high-profile case involving the murder of the 50-year-old UnitedHealthcare CEO, a crime that sparked public outrage and highlighted frustrations with the healthcare industry.
At 28 years old, Mangione entered his plea without a plea agreement, leaving no assurance of leniency at sentencing. Federal prosecutors plan to push for a life sentence, the maximum penalty, during his sentencing scheduled for December 18. The plea could be considered a mitigating factor by U.S. District Judge Margaret Garnett in determining Mangione’s punishment.
The guilty plea also allowed Mangione’s legal team to file a motion to dismiss state murder and weapons charges, citing New York’s prohibition on double jeopardy. Jamie McDonald, the Manhattan U.S. Attorney, emphasized that no special treatment or concessions were made for Mangione. Thompson’s family expressed that the plea was a significant step toward justice and urged the court to ensure that the sentencing reflects the gravity of the crime.
Prior to the guilty plea, Mangione detailed challenges with his insurance following a back injury without elaborating. He recounted posing as a wealthy investor to gain access to information about UnitedHealthcare’s 2024 investor conference and constructed a gun part using a 3D printer before traveling to New York with the intent to kill Thompson.
UnitedHealth Group expressed gratitude to law enforcement for apprehending Thompson’s killer. Mangione, who had previously pleaded not guilty to federal charges, saw murder and weapons charges dismissed earlier due to legal technicalities, eliminating the death penalty possibility in the federal case.
In a separate state case, Mangione faces charges of terrorism, murder, weapons, and forgery. The terrorism charges were dropped in 2025, and a trial is set for September 8. Mangione could face 25 years to life in prison if convicted of second-degree murder. His defense team has invoked New York’s double jeopardy law to seek dismissal of the state case, claiming it would violate his constitutional rights.
Prosecutors are poised to contest the motion, affirming their commitment to seeking justice for Thompson and his family. New York’s double jeopardy law allows exceptions for crimes with distinct elements or different aims. Despite the variations, legal experts anticipate challenges in arguing that the trial should proceed due to the shared intent to kill, a critical component in both the stalking and murder charges.
