Luigi Mangione on Friday has pleaded guilty to the two remaining charges against him in the death of UnitedHealthcare CEO Brian Thompson in December 2024. The charges of interstate stalking resulting in death and stalking through use of interstate facilities resulting in death, filed in the US District Court for the Southern District of New York, both have a maximum penalty of life in prison without parole.

“I shot Mr. Thompson and he died. I knew what I was doing was illegal,” Mangione told the court during his allocution. He also said that he had never been treated or hospitalized for any mental illness or addiction, and that his mind was clear during the hearing.

Mangione does not have a plea deal with the federal government. Instead, he will face sentencing on December 18. Federal prosecutor Jamie McDonald said that the government would seek life imprisonment.

On January 30, Judge Margaret Garnett threw out two of the four charges against Mangione, including “murder through use of a firearm during and in relation to the stalking crimes charged…” A conviction on this charge would have made Mangione eligible for the death penalty.

Mangione still faces state charges in the case, scheduled for September 8. Mangione’s defense lawyer, Karen Friedman Agnifilo, filed a motion to dismiss the state’s second-degree murder and firearms charges, arguing a violation of due process and double jeopardy.

New York’s double jeopardy (when previous prosecution bars subsequent prosecution) statute is broader than the protection offered by the US Constitution. However, it includes nine narrow exceptions. Friedman Agnifilo’s motion argues that none of the exceptions apply, but she preemptively challenged CPL § 40.20(2)(b), “Each of the offenses as defined contains an element which is not an element of the other, and the statutory provisions defining such offenses are designed to prevent very different kinds of harm…” and 40.20(2)(f), “One of the offenses consists of a violation of a…provision of another jurisdiction, which offense has been prosecuted…and …been terminated by a court order…founded upon insufficiency of evidence to establish some element of such offense which is not an element of the other offense.”

In court for his guilty plea, Mangione for the first time described how he learned where UnitedHealthcare would hold its annual investor convergence in December 2024. He also learned who would attend. Mangione said that he printed a gun with a 3-D printer and affixed it with a silencer (suppressor). Defense attorney Friedman Agnifilo said that Mangione took full responsibility for Thompson’s death.
