Luigi Mangione said Friday he is pleading guilty to both counts of federal stalking charges connected to the 2024 killing of UnitedHealthcare CEO Brian Thompson, a major development that could complicate New York prosecutors’ separate murder case against him.
Mangione, 28, pleaded guilty in Manhattan federal court to two stalking charges resulting in Thompson’s death. Each count carries a maximum sentence of life in prison.
The plea came weeks before Mangione was scheduled to stand trial in New York state court on charges including second-degree murder in the Dec. 4, 2024, shooting of Thompson outside a Midtown Manhattan hotel.
Federal prosecutors initially brought additional murder and firearms charges, and former Attorney General Pam Bondi directed prosecutors to seek the death penalty. But U.S. District Judge Margaret Garnett dismissed the death-eligible counts in January, leaving the two stalking charges.
The failed death penalty effort has also given Mangione’s lawyers an opening to exploit an unusual federal prosecution, former federal prosecutor Neama Rahmani said. Federal authorities typically do not bring murder cases when state prosecutors are already handling them, he told LiveNOW from Fox, but the remaining stalking charges could now be used to challenge Bragg’s state case on double-jeopardy grounds.
How long could Mangione face in prison?
The Justice Department did not announce a negotiated plea agreement ahead of time in connection with Friday’s hearing.
Mangione now faces up to a possible life sentence in federal prison, though the court will set his punishment at a later hearing after receiving recommendations from prosecutors, his lawyers, and the U.S. Probation Office. Legal experts say the plea likely will not result in a sentence less than 30 years in prison, meaning with benefits included for time served, Mangione could face prison time until at least age 53.
The federal case has drawn unusual attention because it overlaps with the state prosecution, which is scheduled to begin next month. State prosecutors have accused Mangione of second-degree murder, a charge that carries a possible sentence of 25 years to life.
Prosecutors have alleged that Mangione stalked Thompson before shooting him as the executive walked to a UnitedHealth Group investor conference. Mangione had pleaded not guilty in both the federal and state cases before Friday’s hearing.
Meanwhile, members of Thompson’s family were seated in the courtroom on Friday, according to Fox 5 New York.
State murder trial faces new uncertainty
Mangione’s guilty plea is expected to trigger a renewed fight over whether New York can proceed with its murder case.
New York’s double-jeopardy protections can be broader than the federal Constitution’s protections. Although federal and state authorities can generally prosecute the same conduct under the “dual sovereignty” doctrine, New York law can bar a subsequent state prosecution in certain circumstances when a defendant has already been convicted federally for the same criminal transaction.
Defense lawyer Karen Friedman Agnifilo repeatedly argued that the parallel cases subjected him to two trials for the same alleged conduct. As Mangione was led from a Manhattan courtroom in February, he told reporters, “One plus one is two. Double jeopardy by any common-sense definition.”
His lawyers are likely to argue that the federal stalking conviction and state murder charges arise from the same conduct: the alleged stalking of Thompson, the shooting, and the subsequent flight from New York.
Manhattan District Attorney Alvin Bragg’s office is expected to counter that the statutes address different harms. The federal case concerns stalking resulting in death, while the state case alleges intentional murder.
Manafort case offers a possible guide
The dispute could echo the case of former Trump campaign chairman Paul Manafort, whose New York fraud charges were dismissed after federal convictions involving substantially overlapping conduct.
A New York judge found the factual overlap between Manafort’s federal and state cases was extensive. An appellate court later upheld that ruling. Notably, current Attorney General Todd Blanche was his attorney at the time.
The comparison is not exact. Mangione’s federal charges are for stalking resulting in death, rather than murder, and prosecutors can argue that the elements and purposes of the federal and state laws differ.
Rahmani said Mangione’s plea could be a strategic gamble. If a state court concludes double jeopardy does not apply, Mangione could still face a murder trial after admitting under oath to the federal stalking allegations.
UNEXPECTED HEARING IN LUIGI MANGIONE TRIAL STIRS RUMORS OF PLEA DEAL
A conviction in the federal case does not automatically end the state prosecution. The question will be whether New York courts view both cases as stemming from one criminal transaction or as distinct offenses that may be separately tried.
The guilty plea nevertheless puts the state case in immediate jeopardy and creates a high-stakes legal fight over whether Mangione can be tried for Thompson’s death a second time.
