Mangione Pleads Guilty to Federal Charges in CEO Killing

Luigi Mangione, accused of killing UnitedHealthcare CEO Brian Thompson on a Manhattan street in December 2024, pleaded guilty Friday to federal stalking charges. The plea comes ahead of his scheduled January federal trial and September state murder trial.

The pretrial conference before U.S. District Judge Margaret Garnett concluded with Mangione admitting to shooting Thompson outside the Hilton Hotel on Sixth Avenue while walking to an investors' event. According to CBS News, Mangione told the judge, 'Yes,' when asked if he was prepared to plead guilty.

Mangione faces two federal charges: interstate stalking resulting in death and stalking through the use of interstate facilities resulting in death, each carrying a possible life sentence. Sentencing is scheduled for December 18, 2025. If he pleads guilty, his attorneys may argue that New York's double jeopardy law prevents him from being prosecuted for murder in the state case.

Thompson's widow, Paulette Thompson, made a rare public appearance to watch Mangione admit to shooting her husband according to The Daily Mail. The Thompson family had suffered horrific stalking and abuse after Brian Thompson's killing. Fake bomb threats were made against two of the Thompson family's homes in Maple Grove, Minnesota.

Prosecutors say their case includes hundreds of hours of surveillance footage, fingerprints, DNA, a mobile phone, and a gun matching ballistics from Thompson's killing according to The Guardian. Mangione was arrested five days after the shooting at a McDonald’s in Altoona, Pennsylvania.

Mangione explained his motive: severe back injury and experience with the U.S. healthcare system drove him to kill Thompson, although he was not specifically a customer of UnitedHealthcare. The company has a large reputation for denying claims to customers, especially compared to other insurers according to Salon.

Mangione also said in court that he researched details of UnitedHealthcare’s annual investor conference after suffering a broken back and navigating the health insurance system. He then used a 3-D printer to make part of a gun and traveled to New York with the intent of killing Thompson according to TimesLIVE.

Judge Gregory Carro ruled that the jury in Mangione's upcoming murder trial will remain anonymous due to concerns about harassment or intimidation. The judge also ordered an overflow courtroom to accommodate journalists and members of the public if the main courtroom reaches capacity according to Al Jazeera. Jury selection is scheduled for September 8, and the trial is expected to last about six weeks.

The state murder trial has been postponed following Mangione's federal guilty plea. In a brief written order on Monday, Judge Carro gave prosecutors until October 9 to respond to Mangione's motion arguing that New York's double jeopardy law prohibits his prosecution for the same conduct in both federal and state courts. The judge set Mangione's next appearance in state court for December 10, meaning the trial will not go forward as previously scheduled on September 8.
