Luigi Mangione Expected to Plead Guilty Friday in Federal Case Over UnitedHealthcare CEO Killing

Luigi Mangione is expected to plead guilty Friday to federal charges connected to the December 2024 killing of UnitedHealthcare CEO Brian Thompson, according to sources cited by the New York Post. The 28-year-old is scheduled to appear at a morning hearing in Manhattan federal court.

Mangione is charged in the federal case with two counts of stalking resulting in death, stemming from the December 2024 killing of Thompson on a Manhattan sidewalk, according to the Post.

Mangione would still likely face a potential life sentence if he were to plead guilty in federal court, the Post reported. But such a deal could cripple a separate state case, where a trial is set to start September 8, because of New York's rules against double jeopardy — being tried twice for the same crime.

The separate New York state case creates a significant complication. Manhattan prosecutors have a state murder trial scheduled to begin September 8, and New York's double jeopardy protections generally bar prosecuting someone twice for the same underlying conduct once a case has been resolved. A federal guilty plea entered now, days before that state trial, could scramble or effectively end the state's ability to prosecute Mangione for the same killing, according to the Post.

That tension puts prosecutors in an unusual position: if the federal plea moots the state prosecution, the case's outcome could be effectively decided by the sequence of proceedings rather than by a state jury.

Mangione has become a polarizing figure since his arrest, with some online commentators treating him sympathetically amid frustrations with health insurance denials and billing practices. That sympathy does not change the facts reported by the Post: Thompson was killed on a Manhattan sidewalk in December 2024, and Mangione now faces federal stalking-resulting-in-death charges in connection with that killing.

Friday's hearing, per the Post's sourcing, is expected to be the venue where Mangione enters his federal plea. The Post's report is based on sourcing rather than an on-the-record confirmation from prosecutors or Mangione's defense team.
