Mangione admits killing healthcare CEO and pleads guilty to federal charges

Luigi Mangione admitted to killing UnitedHealthcare CEO Brian Thompson and pleaded guilty to federal charges of interstate stalking resulting in death. On December 4, 2024, Mangione shot Thompson, a 50-year-old father of two, in midtown Manhattan after learning the healthcare company would hold an investor conference in the city that month.

Mangione faced a maximum sentence of life in prison for the federal charges. Thompson's family called the plea "an important step toward justice." Mangione's attorneys argued that the state case violates double jeopardy, as he has already pleaded guilty to federal charges. The Manhattan District Attorney's office remains committed to pursuing the state prosecution.
