Luigi Mangione is expected to appear in federal court in Manhattan on Friday, August 14, 2026, in a major development surrounding the fatal shooting of UnitedHealthcare CEO Brian Thompson. Mangione could plead guilty to federal charges connected to Thompson’s death, although the plea had not been formally entered at the time of reporting and could still change.
Thompson was shot on December 4, 2024, outside a Manhattan hotel as he was heading to UnitedHealth Group’s annual investor conference. Mangione, 28, was subsequently arrested in Pennsylvania five days later and has faced separate federal and New York state proceedings over the killing.
The federal case now centers on stalking charges resulting in death, which could carry a sentence of life in prison. A previous federal ruling dismissed murder and weapons charges on legal grounds, removing the possibility of a federal death sentence.
The potential plea could also have significant consequences for Mangione’s separate New York murder case, which is scheduled for trial beginning September 8. Prosecutors and defense lawyers are expected to continue debating whether a federal resolution affects the state prosecution under double-jeopardy principles.
For now, the key development is the federal hearing and whether Mangione formally changes his plea. The case remains one of the most closely watched criminal proceedings in the United States.
