Luigi Mangione pleads guilty in federal case related to UnitedHealthcare CEO killing

Mangione admitted he stalked and killed UnitedHealthcare CEO Brian Thompson, and his guilty plea could help him challenge the state murder case.

  • On Friday, Luigi Mangione pleaded guilty in Manhattan federal court to two stalking charges resulting in the death of UnitedHealthcare CEO Brian Thompson, with Judge Margaret Garnett scheduling sentencing for December 18, 2026.
  • Mangione detailed his intent to kill an insurance executive after years of enduring severe back pain and frustration navigating the health system, confessing he used a 3D-printed pistol to ambush Thompson outside a Midtown Manhattan hotel.
  • Defense attorney Karen Friedman Agnifilo announced plans to seek dismissal of state murder charges on double jeopardy grounds, while Manhattan District Attorney Alvin Bragg's office maintains the state case involves distinct legal harms and intends to proceed with trial.
  • Thompson's family expressed gratitude that the federal justice system held the perpetrator accountable, stating in a statement the plea marks "an important step toward justice for Brian and for our family."
  • As legal battles over double jeopardy protections intensify, the court must determine whether the federal guilty plea bars the state from pursuing further prosecution ahead of the scheduled September 8 trial and December 18 sentencing.
