Luigi Mangione is expected to plead guilty on Friday to federal charges related to the 2024 killing of UnitedHealthcare CEO Brian Thompson in Manhattan. The anticipated plea arrives less than a month before Mangione is scheduled to stand trial in New York state court on second-degree murder charges.
Federal prosecutors and defense lawyers are expected to discuss a possible plea deal during a scheduled conference in Manhattan federal court, according to sources familiar with the matter. The 28-year-old faces two federal stalking charges resulting in death, each carrying a maximum sentence of life imprisonment, after U.S. District Judge Margaret Garnett dismissed harsher federal murder and weapons charges in January.
While the exact terms of the expected plea remain undisclosed, legal analysts note that an open guilty plea would leave the ultimate sentence up to the presiding judge while opening avenues for the defense. TMZ founder and former attorney Harvey Levin told viewers that the discussions would probably involve a guilty plea to murder.
Federal Court Proceedings And The Dismantling Of The Death Penalty Case
Mangione’s legal path shifted significantly when Judge Garnett tossed out the federal charges that originally made him eligible for the death penalty. The Justice Department had sought the death penalty following Mangione’s arrest.
Authorities arrested Mangione in December 2024 at a McDonald’s in Altoona, Pennsylvania, following a multi-state manhunt. Investigators confiscated a notebook containing plans to target Thompson outside a midtown Manhattan hotel where UnitedHealthcare was hosting an investor conference. Police reported finding shell casings etched with the words delay,

and depose.
The Double Jeopardy Debate In New York State Court
The core strategic value of a federal guilty plea for Mangione’s defense lies in its potential to derail his separate state prosecution. Mangione pleaded not guilty in New York state court to nine felony counts, including second-degree murder and weapons possession, with a state trial slated to begin with jury selection under Justice Gregory Carro on September 8.
Defense attorneys have consistently argued that prosecuting Mangione in both federal and state courts violates double jeopardy principles. New York state law provides protections against multiple prosecutions for the same act.
However, state prosecutors intend to fight any dismissal attempt. Representatives for the Manhattan District Attorney’s Office filed a letter arguing that if a proposed federal guilty plea would operate to defeat a just outcome in the state prosecution, the People could advise the federal district court if that consequence, and the court should consider that fact in deciding whether to accept the plea, as well as any opposition by the victim’s family to such a resolution.
Mitigating Circumstances And Legal Expert Perspectives
Legal observers note that an open plea allows the defense to introduce mitigating factors before sentencing.
“What this opens the door to is that Mr. Mangione could, in federal court, present mitigating circumstances in order to convince the judge to give him a sentence less than a life sentence.”

NBC News legal analyst Danny Cevallos pointed out that resolving the federal matter could complicate the state’s path forward, depending on how courts interpret New York’s restrictive double jeopardy statutes. Previous plea negotiations between prosecutors and defense counsel took place ahead of a June hearing but ultimately did not result in an agreement.
