Mangione pleads guilty in federal court for UnitedHealthcare CEO killing
Luigi Mangione admits to planning and executing the fatal shooting of Brian Thompson, citing healthcare grievances, while defence counsel moves to dismiss concurrent New York state proceedings.
Luigi Mangione, 28, has pleaded guilty to federal charges of interstate stalking resulting in death for the fatal shooting of UnitedHealthcare CEO Brian Thompson in Manhattan on 4 December 2024. Appearing in Manhattan federal court, Mangione admitted to planning the attack, travelling to New York, and shooting Thompson from behind using a 3D-printed gun equipped with a silencer. He cited his personal experiences with the healthcare system, specifically enduring severe pain from a broken back, as the motivation for the killing.
Mangione detailed his premeditation to the court, stating he emailed UnitedHealthcare posing as an investor to gather information about their annual investor conference. He confirmed he crossed state lines with the intent to kill and executed the shooting on the morning of 4 December. The federal sentencing is scheduled for 18 December, with prosecutors recommending a term of 24 to 30 years, though the maximum penalty is life imprisonment without parole.
Judge Margaret Garnett clarified that the prosecutors’ sentencing recommendation of 24–30 years is not binding and that she retains the authority to impose the maximum life sentence. Mangione’s legal team, led by Karen Friedman Agnifilo, argued that the federal guilty plea constitutes acceptance of "full responsibility" for the death, reinforcing the double jeopardy defence against state charges.
The plea introduces significant legal complexity regarding Mangione’s concurrent New York state case, which includes eight charges such as second-degree murder and criminal possession of a weapon. His lawyers have filed motions to dismiss these state charges, arguing that prosecuting him twice for the same act violates constitutional protections. However, the Manhattan District Attorney’s office has stated it intends to proceed with the state prosecution and litigate the defence motions.
Thompson’s family issued a statement expressing gratitude for federal accountability but emphasised their continued pursuit of justice in New York state and Pennsylvania courts. While acknowledging the federal plea as an important step, the family indicated they remain focused on ensuring the sentencing reflects the severity of the crime and pursuing all available legal avenues.
