Luigi Mangione pleads guilty to causing UnitedHealthcare CEO’s death in federal case

Mangione also faces separate state trial over killing of UnitedHealthcare CEO Brian Thompson in Manhattan, due to start on 8 September

A hurriedly scheduled hearing for Luigi Mangione’s federal case in the killing of UnitedHealthcare CEO Brian Thompson is set for later on Friday morning, fueling speculation that he might plead guilty in these proceedings.

Mangione faces two stalking counts in his federal case, as well as murder and weapons charges in a separate New York state case. He has pleaded not guilty in both cases. Both the federal and state cases could lead to a life prison sentence.

The shooting of the senior business executive on a Manhattan street in 2024 triggered a manhunt that ended in Mangione’s arrest in a Pennsylvania fast food restaurant. But it also sparked a public outpouring of anger at the US for-profit healthcare industry, and Mangione has attracted a hardcore set of supporters.

The hearing, which the Manhattan federal judge Margaret Garnett scheduled on 11 August after a joint request from Mangione’s lawyers and prosecutors, has raised eyebrows among court-watchers given its surprising timing.

Hours before the joint request for a conference, Mangione had appeared for the final pre-trial conference in his Manhattan state court case, which goes to trial on 8 September.

The letter requesting a conference was sparse on details, fanning the flames of speculation that a plea deal might have been struck in the high-profile case, which has become one of the most eagerly anticipated in recent US criminal history.

The request for a hearing offered little insight at what might be discussed. The letter, submitted by prosecutor James McDonald, stated: “The parties write jointly to request a conference with the Court. Based on communications with Chambers, we understand that the Court is available to hold the conference on Friday, August 14, 2026, at 11:00 am.”

If Mangione does plead guilty in the federal case, it could send his state case into potential disarray. New York’s double jeopardy law could possibly prohibit his state-level prosecution.

New York state law holds that “a person may not be twice prosecuted for the same offense” and “a person may not be separately prosecuted for two offenses based upon the same act or criminal transaction”. A New York state appeals court decision notes , though, that these explanations come before the word “unless” and a list of exceptions.

During his state proceeding on Tuesday, Judge Gregory Carro discussed trial logistics.
