In a procedural update Wednesday in a New York courtroom, a judge confirmed that defense attorneys for Luigi Mangione — the man accused of fatally shooting UnitedHealthcare CEO Brian Thompson in late 2024 — will mount a psychiatric-based defense during his upcoming state murder trial.
According to reporting from CBS News, the BBC’s official partner for U.S. news coverage, Mangione’s legal team has informed state judge Gregory Carro that they will seek to prove their client was experiencing severe, debilitating extreme emotional disturbance at the time of the fatal shooting. Mangione has entered not guilty pleas to all charges in both the state and federal legal cases stemming from the December 4 attack in midtown Manhattan.
If the trial jury accepts the psychiatric defense argument, the legal outcome could see Mangione convicted of the lesser charge of manslaughter rather than first- or second-degree murder, a shift that would drastically reduce any potential sentence if found guilty. Judge Carro also confirmed Wednesday that he will order the unsealing of court documents tied to the defense’s strategic plan, per CBS’s reporting.
Photographs from the proceeding show Mangione present in the Manhattan courtroom for Wednesday’s strategy discussion. His initial court appearance was scheduled for Tuesday, but the hearing was called off at the last minute following a reported procedural error on the part of the prosecution team. The state murder trial is currently on track to open with jury selection on September 8.
Mangione, an Ivy League graduate from an affluent family based in Maryland, also faces unresolved federal stalking charges that carry a maximum potential penalty of life imprisonment if he is convicted. Earlier this year, federal prosecutors dropped more severe federal murder and firearms charges against him, clearing the way for the state prosecution to move forward first.
The fatal shooting that sparked the case took place on December 4, 2024, when Thompson — a 50-year-old father of two — was shot from behind by a masked gunman as he arrived at a Manhattan hotel for UnitedHealthcare’s annual investor conference.
