Luigi Mangione reveals motive for CEO's killing after pleading guilty in federal case

Luigi Mangione pleaded guilty in connection with the 2024 shooting death of UnitedHealthcare CEO Brian Thompson. The 28-year-old admitted to stalking and killing Thompson outside a Manhattan hotel. He faces potential life imprisonment. Mangione also remains charged with state murder in New York. Justice correspondent Ali Rogin reports that Mangione expressed no remorse during his brief statement in court, where Thompson's family was present and reportedly cried.

The government's case against Mangione was strong, including video footage, the murder weapon, and his diary detailing the plan. He was charged with two counts of stalking resulting in Thompson's death, but only facing federal charges, as state-level murder charges are rare. However, his defense argued that the simultaneous prosecution violated the constitutional principle of double jeopardy.

Mangione claimed his motivation was years of back pain and his belief that the health insurance system was obstructing his care. He planned the murder after learning UnitedHealthcare was hosting an investor summit in Manhattan, where he posed as an investor to gather information about the meeting.
