Luigi Mangione appeared in a federal courtroom in New York, pleading guilty to fatally shooting UnitedHealthcare chief executive Brian Thompson on a Manhattan street in December 2024. The 28-year-old admitted to using a 3D printer to make a gun and killing Thompson after researching the company's annual conference online. According to Mangione, he shot Thompson because of his experience with the healthcare insurance industry and the fact that UnitedHealthcare had responded promptly to one of his emails. In court, Mangione's speech faltered briefly as he read a statement detailing the events leading up to the shooting, but he ultimately admitted to the crime.

Story summary
Here is a summary of the news story:
Luigi Mangione, 28, has pleaded guilty to two federal charges of stalking with the intent to kill Brian Thompson, the CEO of UnitedHealthcare, who was fatally shot on a Manhattan street in December 2024. Mangione's lawyers had been meeting with federal prosecutors to discuss a potential plea deal, but he entered his guilty plea without one. The guilty plea will likely avoid a federal trial, but it does not guarantee leniency at sentencing. In addition to the federal charges, Mangione also faces state murder charges in connection with Thompson's death. His lawyers have now asked that the state case be thrown out due to double jeopardy grounds, and a hearing on this matter is scheduled for 10 December.
