Luigi Mangione Expected To Plead Guilty in Federal Case Over UnitedHealthcare CEO Brian Thompson Killing: Report

Luigi Mangione is expected to plead guilty Friday, August 14, to federal charges linked to the 2024 killing of UnitedHealthcare CEO Brian Thompson in Manhattan, according to sources familiar with the matter. The expected plea comes less than a month before Mangione, 28, is scheduled to face trial in a separate New York state murder case over Thompson’s fatal shooting.

Details of the expected plea remain unclear, including whether Mangione will plead guilty to one or both stalking-related charges in the federal case, the New York Post reported. Sources familiar with the matter stressed that plea negotiations are ongoing and that nothing is final until Mangione himself accepts or enters into a plea deal. His lawyers, the Justice Department and a court spokesperson declined to comment. Luigi Mangione Trial: Gun and Notebook Admitted as Evidence.

Federal Plea Could Affect State Murder Case

If Mangione pleads guilty to the federal charges, his lawyers are expected to seek dismissal of some or all of the charges in his state case. Jury selection in the state case is scheduled to begin next month. The Manhattan District Attorney’s Office declined to comment.

Mangione has pleaded not guilty in the state case to eight felony charges, including second-degree murder and several counts related to criminal possession of a weapon. If convicted in the New York case, he faces the possibility of life in prison.

Death Penalty Was Initially Sought

The Justice Department initially sought the death penalty against Mangione in the federal case. US District Judge Margaret Garnett blocked the death penalty in January. If Mangione is convicted on the federal charges, he could face a life sentence.

It is also possible that the terms of any plea agreement could change before or during Friday’s hearing. Sources said Mangione could reverse his decision at any time before the plea is formally entered.

Mangione Accused in Thompson Killing

Mangione is accused of fatally shooting Thompson, 50, as he walked alone outside the Hilton Hotel in midtown Manhattan in December 2024. The shooting occurred hours before UnitedHealthcare was scheduled to hold an investor conference at the hotel.

Surveillance footage showing a masked gunman shooting Thompson triggered a dayslong, multistate manhunt. The search ended with Mangione’s arrest at a McDonald’s restaurant in Altoona, Pennsylvania.

Authorities confiscated a notebook when Mangione was arrested. Prosecutors have said it belonged to Mangione and contained plans to kill Thompson.

Double Jeopardy Claim

Mangione’s lawyers have argued since the beginning of the federal and state cases that their client is a victim of double jeopardy. The two cases have proceeded separately, with the federal prosecution involving stalking-related charges and the state prosecution including murder and weapons charges.

A guilty plea in the federal case could therefore have significant implications for the state prosecution, although the precise effect would depend on the terms of any agreement and subsequent court decisions.

Killing Sparked Healthcare Debate

Thompson’s killing and Mangione’s subsequent arrest have also generated a wider public debate over the US healthcare system, including its costs and perceived shortcomings. Mangione has attracted a following among some supporters, with some portraying him as a folk hero. He has also been referenced by some people charged with other crimes.

Supporters have regularly appeared at his pretrial proceedings. The expected federal plea now comes as Mangione faces potentially significant consequences in both the federal and state cases, with the outcome of Friday’s hearing likely to clarify the next stage of the prosecutions.
