Luigi Mangione pleaded guilty in New York federal court to stalking and killing UnitedHealthcare CEO Brian Thompson in December 2024. Mangione admitted to shooting Thompson on a Manhattan street, stating he knew his actions were illegal. He faces a possible life sentence in federal court, with sentencing scheduled for December 18. His lawyers immediately filed a motion in New York state court to dismiss murder and firearms charges, arguing that the federal plea bars state prosecution under New York's double jeopardy law. Mangione, an Ivy League graduate, said he acted after years of severe back pain and frustration with the health insurance system. He used a 3D-printed gun and posed as an investor to gain information about UnitedHealthcare's investor conference. The case highlights the intersection of federal and state prosecutions and the legal implications of double jeopardy.
