One of three prosecutions
People of the State of New York v. Luigi Mangione
People of the State of New York v. Luigi Mangione is the state murder prosecution over the December 2024 killing of UnitedHealthcare chief executive Brian Thompson in Manhattan. The Manhattan District Attorney announced an eleven-count indictment on December 17, 2024, and the case was assigned to Justice Gregory Carro in Part 32 of the Supreme Court, New York County. A defense motion to dismiss counts three through ten is pending. The September trial was postponed, and the next court date is December 10, 2026.

The September 16, 2025 decision dismissed the two murder counts charged as acts of terrorism; nine counts, including second-degree murder, were unaffected.
On August 14, 2026, after the federal guilty pleas, the defense asked the court to dismiss count three and counts four through ten on double-jeopardy and due-process grounds. The court has not ruled, and count eleven is outside the request.
On August 17, 2026, the court canceled September 8 jury selection and postponed the state trial without setting a replacement trial date. Prosecutors must respond to the dismissal motion by October 9, the defense may reply by October 30, and the next court date is December 10.
