Luigi Mangione, 28, has pleaded guilty in a Manhattan federal court to two counts of interstate stalking resulting in death for the December 2024 killing of UnitedHealthcare CEO Brian Thompson. During his plea, Mangione admitted, “I shot Mr. Thompson in Manhattan and he died,” and acknowledged, “I knew what I was doing was illegal.” He detailed using a ruse, posing as an investor to gather information about Thompson’s schedule, and using a 3D-printed firearm equipped with a silencer. He cited motivations rooted in severe physical pain from a spinal injury and frustration with the American healthcare insurance system. Newly unsealed court transcripts revealed that Mangione’s legal team, led by Karen Friedman Agnifilio, sought to conduct plea negotiations privately in June to avoid early public signaling on the docket.
