A New York state judge has effectively delayed the murder trial of Luigi Mangione, the 28-year-old accused in the fatal shooting of UnitedHealthcare CEO Brian Thompson, after Mangione pleaded guilty last week to related federal charges.
State court pauses amid double jeopardy motion
Justice Gregory Carro issued a brief written order Monday that gives Manhattan prosecutors until Oct. 9 to respond to a defense motion asking the court to dismiss the state murder and weapons counts. The judge set Mangione’s next state-court appearance for Dec. 10, ensuring the case will not proceed to jury selection on Sept. 8 as previously scheduled.
Defense lawyers argue that Mangione should not be punished twice for the same conduct, invoking New York’s double jeopardy protections after the defendant entered a guilty plea in federal court to stalking-related charges. Manhattan prosecutors have said they intend to continue pursuing the state-level case.
"...navigating the obstacles of the health insurance system and witnessing similar experiences of countless others,"
Mangione has admitted he shot Thompson outside a Manhattan hotel on Dec. 4, 2024, following a dispute over his treatment for severe back pain and interactions with health insurers, according to court filings. In federal court, the defendant pleaded guilty to stalking charges after other federal counts including murder were dropped.
What the schedule looks like now
- Dec. 4, 2024 — Brian Thompson was shot outside a New York City hotel.
- Sept. 8, 2026 — Original date set for jury selection in state trial (now postponed).
- Oct. 9, 2026 — Deadline for prosecutors to file their response to the defense motion.
- Dec. 10, 2026 — Next state-court appearance for Mangione.
| Date | Event |
|---|---|
| Dec. 4, 2024 | Shooting of Brian Thompson |
| Aug. 2026 | Mangione pleads guilty in federal court to stalking charges |
| Oct. 9, 2026 | Prosecutors' deadline to respond to dismissal motion |
| Dec. 10, 2026 | Next state-court appearance |
The defense’s double jeopardy claim rests on the interaction between federal plea agreements and state prosecution, an area where New York law can provide broader protections than the U.S. Constitution. The brief order from Justice Carro does not resolve that legal question; it simply sets a schedule for written briefing and pauses trial preparations in the meantime.
Manhattan prosecutors, who have maintained they will move forward with the state charges, now have until the October deadline to outline why the state case should proceed. The defense will have an opportunity to reply after that filing.
For the local community, the delay means the high-profile proceedings will continue through the autumn and into winter, with key legal questions about charging and sentencing to be hashed out on paper before any jury hears evidence. Families of the victim and witnesses can expect additional months before the case reaches a courtroom for trial testimony.
I'll continue to monitor filings in Manhattan Criminal Court and report developments as prosecutors and defense counsel file their briefs and court dates are adjusted.
