AI Summary
5 min readOn August 14, 2025, Luigi Mangione stood in a federal courtroom and, in a flat, matter-of-fact voice, told a judge exactly what he did. “I shot Mr. Thompson,” he said, referring to Brian Thompson, the CEO of UnitedHealthcare, whom he killed on a Manhattan sidewalk in December 2024. Mangione explained that he had learned UnitedHealthcare would hold its annual investor conference in New York, traveled there with the intent to kill, and carried it out. There was no remorse, no anguish. Thompson’s widow was in the room, crying, and had to be comforted by a relative. Mangione, in beige jail garb, simply recited his statement and was led back into custody. The guilty plea—to two counts of stalking in federal court—was a surprise to many who had expected a protracted legal battle. But as ABC News’s chief investigative correspondent Aaron Katersky, who has covered the case from the start, explains, the evidence against Mangione was overwhelming: video of the shooting, eyewitnesses, the murder weapon pulled from his backpack, and notes that prosecutors took as a motive. The plea was not a deal; it was an “open plea,” meaning Mangione admitted to the full charges with no promise of a specific sentence, turning instead to the judge for leniency.
