Jury selection had been scheduled to begin on Sept. 8, but the federal case has raised new double jeopardy arguments. Prosecutors must respond by Oct. 9, while the defense has until Oct. 30 to reply. Judge Gregory Carro set the next court date for Dec. 10.

Trial adjournment and new schedule
The New York state murder proceeding against Luigi Mangione, 28, will not move forward with jury selection on Sept. 8 as previously planned. In an order published Monday afternoon, Aug. 17, Judge Gregory Carro postponed the case and scheduled the next adjourned date for Dec. 10. The delay gives both sides time to address the defense request to dismiss the state charges.
The case is being pursued in Manhattan, where prosecutors allege that Mangione killed UnitedHealthcare CEO Brian Thompson. The scheduling change follows developments in a separate federal prosecution and does not itself resolve whether the state case will proceed.
Defense motion and double jeopardy concerns
Mangione’s defense team moved to dismiss the New York charges after he pleaded guilty last week to federal stalking and murder counts. The lawyers argue that the completed federal case creates double jeopardy concerns, which generally involve limits on prosecuting a person more than once for the same conduct.
The legal issue is complicated by differences between New York law and the U.S. Constitution. The case materials described New York’s double jeopardy protections as more favorable to Mangione now that the federal proceeding has been resolved. The judge has set deadlines for written arguments before deciding how the state prosecution should continue.
Federal guilty plea and the killing
Mangione pleaded guilty Friday, Aug. 14, in federal court to stalking Brian Thompson across state lines with the intent to kill him and to murdering the executive. According to the case account, Thompson was shot in the back outside a Manhattan hotel on Dec. 4, 2024, while he was expected to meet with investors.
Thompson was 50 and a father of two from Minnesota. Mangione has admitted responsibility in the federal case, but he has not yet been sentenced. The federal charges and the pending New York charges remain separate proceedings unless the state court grants the defense motion.
Prosecutors’ response and potential penalties
Manhattan prosecutors have said they intend to continue pursuing their case against Mangione. They have until Oct. 9 to respond to the motion to dismiss, after which the defense may file its reply by Oct. 30. The court’s Dec. 10 date provides a point for further proceedings after those submissions.
If the state case reaches trial and Mangione is convicted of second-degree murder, the top charge carries a potential sentence of 25 years to life in prison. In the federal case, sentencing guidelines recommend a maximum of about 30 years, but Judge Margaret Garnett is not required to follow them. The federal prosecution also carries a possible sentence of life imprisonment without parole.
What happens next in state and federal court
The immediate question is whether the New York court will dismiss the state charges on double jeopardy grounds. The court must review the prosecution’s opposition and the defense’s reply before determining whether the state trial can proceed.
Separately, the federal court must schedule Mangione’s sentencing after his guilty plea. Until both matters are addressed, the state trial remains delayed rather than canceled. The Dec. 10 date could bring a ruling or further instructions about the next steps in Manhattan Criminal Court.
| Number | Key Point |

Summary
Mangione’s federal guilty plea has changed the timetable and legal posture of the New York murder case. The state court will consider the defense’s double jeopardy motion after receiving filings from both sides, while the federal court prepares for sentencing. The Dec. 10 hearing will be the next significant scheduled event in the state matter.
