Mangione pleads guilty to federal stalking charges in CEO killing

Luigi Mangione, 28, pleaded guilty Friday to federal stalking charges related to the killing of UnitedHealthcare CEO Brian Thompson in Manhattan, New York, during a December 2024 ambush. Mangione admitted in court that he followed Thompson to an investor conference, posing as an investor to gain access to the event, and subsequently shot him on a city street. The incident occurred just days before the annual UnitedHealthcare Investor Day, where Thompson was set to speak. Mangione, dressed in a beige jail uniform and shackled at the ankles, described the attack during his court appearance. He stated, “On the morning of Dec. 4, 2024, I shot Mr. Thompson in Manhattan, and he died.” His account included using a 3D-printed firearm to carry out the attack. Thompson's wife, Paulette, sat in the courtroom, visibly emotional, wiping tears from her eyes as Mangione spoke. Federal prosecutors are anticipated to request a life sentence when Mangione is sentenced on December 18. When asked by U.S. District Judge Margaret M. Garnett whether he understood the possibility of spending the rest of his life in prison, Mangione replied affirmatively. The Thompson family issued a statement calling the plea “an important step toward justice,” while noting that Mangione still faces a separate state murder prosecution, which could result in additional time behind bars. The federal prosecutors confirmed that Mangione received no deal or incentive for pleading guilty. They emphasized that the decision was not made to avoid a potential death sentence, which was removed from consideration following the dismissal of a federal murder charge earlier this year. Following the plea, Mangione’s legal team swiftly filed a motion to dismiss the New York state murder case on double jeopardy grounds, citing the federal conviction. Defense lawyer Karen Friedman Agnifilo argued that her client should not face dual prosecutions for a “single tragic event.” However, the Manhattan district attorney’s office expressed its commitment to pursuing the state case, stating it would contest the defense’s attempt to halt proceedings. Surveillance footage captured the attack, showing a masked individual shooting Thompson from behind. The video revealed that the ammunition bore the words “delay,” “deny,” and “depose,” echoing language often used by insurers to refuse claims. This detail, combined with findings that Mangione had privately criticized health insurers as greedy, sparked broader discussions about the industry and elevated Mangione to a symbol among some of its critics. Born a University of Pennsylvania graduate from a wealthy Maryland family, Mangione detailed his personal struggles during his court testimony. He recounted enduring severe pain from a broken back, facing challenges within the health insurance system, and witnessing similar hardships among others. According to authorities, Mangione believed the system had failed him and ruined his life. Mangione was not a UnitedHealthcare customer, as confirmed by police and the company. In response to the case, New York Police Commissioner Jessica Tisch condemned the violence, stating, “To those who idolize Luigi Mangione, I say this: Violence is not a cause. Murder is not a message. And a killer is certainly not a hero.” U.S. Attorney Jamie McDonald echoed these sentiments, adding, “There can be no celebrity in assassination.” Thompson, a leader at one of the largest health insurers in the U.S., was not widely recognized beyond the industry. Trained as an accountant, he spent two decades at UnitedHealth Group Inc. before becoming CEO. His death has left a significant impact, both professionally and personally, marking a pivotal moment in public discourse around healthcare policy and corporate accountability.
