Luigi Mangione expected to plead guilty in killing of UnitedHealthcare CEO

Luigi Mangione, the 28-year-old accused of fatally shooting UnitedHealthcare chief executive Brian Thompson, is expected to plead guilty to federal stalking charges at a hearing Friday in Manhattan federal court, according to The New York Times and reports citing sources familiar with the talks.

The hearing is set for 11 a.m. Friday, August 15, before US District Judge Margaret Garnett. Garnett scheduled it after federal prosecutors and Mangione's defense lawyers jointly asked for a conference in a one-page letter filed late Tuesday, August 11. Court records did not identify the purpose of the session.

Nothing is final. People familiar with the negotiations stressed that talks remain open, and that Mangione could reject any offer or reverse course during the hearing itself. He has pleaded not guilty to both his federal and state charges throughout the proceedings, and reports note he could change his decision at any point, even after walking into the courtroom Friday.

What Mangione faces in federal court

Mangione faces two federal stalking counts, each carrying a maximum sentence of life in prison without the possibility of parole. It is not clear whether he would plead guilty to one count or both. Neither prosecutors nor his lawyers have made the terms of any agreement public.

The federal case once carried the threat of execution. On January 30, 2026, Garnett dismissed two of the four federal counts against Mangione, including a murder charge tied to the use of a firearm that could have brought a death sentence. Prosecutors confirmed in February that they would not appeal, taking capital punishment permanently off the table.

With the murder counts gone, the two remaining stalking charges were set to go to trial in federal court in January 2027. A guilty plea Friday would resolve that case before any jury heard it. It would also mark a sharp turn from Mangione's earlier posture, since he had contested the charges at every stage, challenged the evidence seized at his arrest, and, through his lawyers, fought the government's attempt to seek his execution.

James McDonald, the US attorney for the Southern District of New York, declined to comment on the purpose of Friday's session at a news conference Wednesday. Defense lawyers, a court spokesperson and Justice Department representatives also declined to comment, apart from confirming the 11 a.m. hearing. Court records described the filing only as a joint request, which analysts read as an unusual step so close to a state trial.

How the plea could upend the state case

A federal guilty plea would give Mangione a conviction, and his lawyers have signaled they would use it to attack the separate New York murder case. They plan to argue that New York's double jeopardy protections bar the state from trying him for conduct already resolved in federal court. For that argument to work at all, Mangione must first secure a federal conviction, which a guilty plea would supply.

Double Jeopardy is meant to protect people, and they are using it as a weapon here.

The argument runs into a long-standing exception. Under the 'separate sovereigns' doctrine, the federal government and New York are treated as distinct authorities, and each can charge the same person for the same acts. Gregory Carro, a judge in the state case, previously rejected Mangione's double jeopardy claim as premature, while noting that New York offers broader protection than the federal Constitution once a prior case ends in a guilty plea.

A recent case gives the defense a template. New York prosecutors brought state charges against Paul Manafort after his federal convictions, and courts weighed how far the state could go once a federal case had concluded. Whether the same reasoning helps Mangione would depend on the exact terms of any federal plea and on how a state judge reads New York's exceptions, an interplay analysts have called unusually tangled.

New York's murder trial still looms

Mangione's state trial is scheduled to begin with jury selection on September 8. He faces several counts of second-degree murder and weapons possession, and New York has no death penalty, so the most severe outcome would be a sentence of 25 years to life, or life in prison. Unlike the federal case, the state charges name Thompson directly and describe him as a father of two, language prosecutors have used to keep the human toll of the shooting in front of the court.

It is incredibly complicated.

State prosecutors have room to fight back. They could argue that the murder and weapons charges are materially different from the federal stalking counts, and therefore fall outside New York's double jeopardy bar. Any federal plea Friday is likely to trigger a rush of defense motions seeking to dismiss the state case before jury selection, and the state judge, not the federal court, would decide whether that trial goes forward.

Pretrial fights are already under way in state court. At a hearing Tuesday, the judge ruled the jury would remain anonymous. Defense lawyers objected to what they called a partial exclusion of the press, arguing that limits on media access, including the absence of an overflow courtroom, threatened Mangione's right to a public trial.

The killing that drew national attention

Thompson, 50, was walking to a UnitedHealthcare investor conference outside a Midtown Manhattan hotel on December 4, 2024, when a gunman shot him. Authorities said the words 'deny,' 'delay' and 'depose' were found on shell casings and a bullet at the scene, language widely read as a critique of insurance industry practices. The shooting, captured on graphic surveillance footage, spread quickly online and set off days of national coverage.

A five-day manhunt followed. Mangione was arrested more than 200 miles away at a McDonald's in Altoona, Pennsylvania, after a manager recognized him and called 911. Prosecutors say a handgun in his backpack matched ballistics from the scene, and that a notebook in the bag held writings expressing anger at the healthcare industry and a stated desire to target an insurance executive.

Even so, Mangione, a 2020 University of Pennsylvania graduate who studied computer and information science, drew unusual public support, with some casting the shooting as a protest against rising medical costs and the practices of large insurers. That sympathy has followed the case ever since.

Where the case stands now

Mangione, held at the Metropolitan Detention Center in Brooklyn, met with his lawyers there Thursday morning before Friday's hearing. Nearly 21 months have passed since Thompson was shot on a Midtown sidewalk, and Friday's session could bring the federal chapter of the case to a close, even as the far larger question of the state trial stays unresolved.

Plea talks are not new. Defense lawyers and federal prosecutors discussed a possible deal before a hearing in June, but did not reach an agreement then. The joint request for a hurried hearing so close to the state trial date struck legal observers as a strong signal that a resolution was near, though the same people cautioned that a deal could still fall apart.

What prosecutors want from a plea

The Manhattan District Attorney's Office has signaled it will not sit quietly if Mangione pleads guilty in federal court. Prosecutors there have said they are prepared to lobby the federal judge for a stiff sentence, and to remind the court of the state case they still intend to pursue. They also told the state court they are aware of the public reporting about a possible federal plea.

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 of 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.

Some legal analysts see an open plea as the likeliest route, one in which Mangione admits guilt and leaves his sentence to the judge. That path would let his lawyers present mitigating circumstances and press for a term short of life in prison, while still delivering the federal conviction their double jeopardy strategy depends on.

The victim's family looms over the talks. In its letter, the district attorney's office told the state court that any opposition from Thompson's relatives should weigh on whether the federal judge accepts a plea. Thompson was 50, a father of two, and prosecutors have repeatedly returned to that detail as they press to keep the state case alive.

Thompson led UnitedHealthcare, the insurance arm of UnitedHealth Group. He was shot as he arrived for the company's investor conference, an event Mangione allegedly mocked in his notebook as a gathering of the healthcare industry he blamed for rising costs. The killing, and the wave of online support Mangione later drew, turned an ordinary Manhattan homicide into a national argument over insurance industry practices and the cost of care.

What happens Friday

If Mangione goes through with the plea, the federal case ends and the fight shifts to whether New York can still put him on trial. If the talks collapse, he remains on track for the federal trial in January 2027, and the state trial would proceed with jury selection on September 8. Either way, prosecutors and the victim's family have made clear they intend to be heard before any deal is signed.
