NEW YORK (AP) — Luigi Mangione is expected to plead guilty as early as Friday in the federal case accusing him of stalking and killing UnitedHealthcare CEO Brian Thompson, according to a person familiar with the matter.

The person, who was not authorized to talk publicly about the case and spoke to The Associated Press on the condition of anonymity, cautioned that Mangione could change his mind. If he follows through, it would be a stunning development in a case that rattled business leaders while galvanizing their critics.

Mangione's lawyers, and spokespeople for the Justice Department and Manhattan federal prosecutors, declined to comment.

Mangione is accused of traveling to New York City to ambush Thompson, 50, then shooting him outside a Manhattan hotel on Dec. 4, 2024, as the executive walked to UnitedHealth Group's annual investor conference.

Mangione is due in court on Friday for a hastily scheduled hearing in the federal case, which involves two counts of stalking. It wasn't clear what charge or charges Mangione is expected to plead guilty to. The hearing, in Manhattan federal court, comes as his lawyers have been talking with federal prosecutors about a possible resolution to one of two criminal cases against Mangione in Thompson's death. Previous talks in June broke down.

Mangione, 28, has been charged in both federal and state court in New York and still faces the possibility of a trial in his unresolved state case. Mangione's state murder trial is set to begin Sept. 8. Both sets of charges carried the possibility of a life sentence.

Mangione has pleaded not guilty and has spoken out publicly against the prospect of two trials, telling a judge in February: "It's the same trial twice. One plus one is two. Double jeopardy by any commonsense definition."

Under New York law, a state prosecution could be barred if the federal case is resolved first, but it isn't automatic.

The state's double jeopardy protections kick in if a jury has been sworn in a prior prosecution, such as a federal case, or if that prosecution ends in a guilty plea. Mangione's cases involve different charges arising from the same course of conduct.

Once Mangione pleads guilty, his lawyers could then ask the judge in the state case to throw out those charges on double jeopardy grounds. State prosecutors argue their case is distinct and double jeopardy shouldn't apply.

Mangione's federal charges allege that he traveled across state lines by bus to stalk and kill Thompson and that he used means such as a cellphone, the internet, interstate highways and staying at a hostel that serves out-of-state customers while planning and carrying out the attack. The state charges pertain to the killing itself, as well as firearms offenses.

In a letter last month, state prosecutors objected to the possibility of a guilty plea in the federal case wiping out the state case.
