Luigi Mangione appears for a suppression of evidence hearing in Manhattan Criminal Court on December 18, 2025, in New York City.
New York  — 

Luigi Mangione will not face the death penalty for allegedly killing UnitedHealthcare CEO Brian Thompson in December 2024, a federal district judge ruled.

The decision is a loss for federal prosecutors, who were adamant about pursuing the death penalty in the case.

Judge Margaret Garnett also ruled Friday to allow into Mangione’s trial evidence recovered from his backpack at the time of his arrest.

Law enforcement seized several items from Mangione’s backpack, including a handgun, a loaded magazine and a red notebook – key pieces of evidence that authorities have said tie him to the killing.

Mangione’s attorneys had argued for the evidence to be barred from trial, contending the search of their client’s backpack was illegal because they had not yet obtained a warrant and there was no immediate threat to justify a warrantless search.
