UnitedHealthcare chief executive Brian Thompson was shot and killed in Manhattan on December 4, 2024, and Luigi Mangione was arrested five days later in Pennsylvania. He was charged in New York state court, in federal court, where prosecutors sought the death penalty, and in Pennsylvania. The state terrorism counts and the federal death eligible counts were dismissed, and in August 2026 he pleaded guilty to two federal stalking counts. He has pleaded not guilty to the remaining state charges.
Mangione pleaded guilty on August 14, 2026 to two federal stalking counts and is due to be sentenced on December 18, 2026. Federal prosecutors have said they will seek a life sentence, Reuters reported. He has pleaded not guilty to the remaining New York state charges, his motion to dismiss them on double jeopardy grounds is pending, and a state hearing is set for December 10, 2026. The Pennsylvania case was reported on hold in October 2025.
Brian Thompson, chief executive of UnitedHealthcare, was shot several times at about 6:45 a.m. on West 54th Street near Sixth Avenue and died, according to federal prosecutors. The shooter left the scene on a bicycle, prosecutors said.
Police in Altoona, Pennsylvania arrested Luigi Mangione, then 26, at a fast food restaurant after a worker recognized him, according to federal prosecutors, who said he had a 9mm pistol, a sound suppressor and a false identification. He was also charged in Blair County, Pennsylvania with offenses including carrying a firearm without a license, forgery, tampering with records or identification and false identification to law enforcement, according to CBS New York.
The Manhattan District Attorney announced an 11 count New York State Supreme Court indictment, including one count of first degree murder in furtherance of terrorism and two counts of second degree murder, one charged as an act of terrorism, plus weapons and forgery counts.
A federal complaint charging two stalking offenses, murder through use of a firearm and a firearms offense was unsealed. Mangione was taken into federal custody and appeared before Magistrate Judge Katharine H. Parker, and detention was continued.
Mangione pleaded not guilty to the state indictment before Justice Gregory Carro of the New York State Supreme Court in Manhattan, according to news reports.
Attorney General Pamela Bondi said she had directed federal prosecutors in Manhattan to seek the death penalty.
Mangione's lawyers filed a motion asking the court to bar the government from seeking the death penalty.
A four count federal indictment was filed: interstate stalking resulting in death, cyberstalking resulting in death, murder through use of a firearm and a firearms count.
Federal prosecutors filed formal notice that they would seek a death sentence on Count Three, murder through use of a firearm under 18 U.S.C. 924(j), if Mangione were convicted.
At his arraignment before US District Judge Margaret M. Garnett, Mangione pleaded not guilty to all four counts of the federal indictment, according to the docket.
Justice Carro dismissed the two terrorism counts and kept the second degree murder count and other charges, according to the AP. He rejected as premature a defense argument that the parallel state and federal cases amounted to double jeopardy.
Mangione's lawyers moved to dismiss Counts Three and Four of the federal indictment and to suppress evidence and statements.
A Blair County judge ruled that the Pennsylvania case could not proceed while Mangione is held in New York and declines to appear remotely, and ordered updates every 60 days on his availability, CBS New York and WJAC reported.
Judge Garnett granted the motion to dismiss Counts Three and Four, ruling that the stalking offenses charged were not crimes of violence for the firearm counts. She wrote that the chief practical effect was to remove the death penalty as a possible punishment. In a separate ruling she declined to suppress the backpack and its contents.
Judge Garnett set a schedule with in person jury selection to start on September 8, 2026 for a trial beginning October 13, 2026, according to a later defense filing.
Justice Carro set the state trial for June 8, 2026, the defense told the federal court. Prosecutors had asked in a January 28 letter for a July 1 start, according to the same filing.
Mangione's lawyers asked the federal court to adjust its schedule, arguing that preparing for two trials at once would violate his constitutional rights.
Justice Carro adjourned the state trial to September 8, 2026. Judge Garnett then issued a schedule setting federal opening statements for November 4, 2026 and ordered counsel to stay available for a January 2027 alternative.
Justice Carro ruled that five items taken from Mangione's backpack at the time of his arrest could not be used in the state case, while items found in a later search at the police station, including a handgun and a notebook, were admissible, according to Gray Media.
Judge Garnett issued a new schedule with in person jury selection to begin January 5, 2027 and opening statements on January 25, 2027.
Mangione pleaded guilty before Judge Garnett to interstate stalking resulting in death and cyberstalking resulting in death, the two remaining federal counts, according to the docket. Each carries a maximum of life in prison. Reuters reported there was no plea agreement and that prosecutors said they would seek a life sentence. Sentencing was set for December 18, 2026.
Justice Carro called off the September 8 state trial and gave prosecutors until October 9 to respond to a defense motion to dismiss most state counts under New York's double jeopardy law, Reuters and AP reported. He set a hearing for December 10, 2026.
