Judge Allows Key Evidence in Luigi Mangione Trial Over UnitedHealthcare CEO Killing

A New York judge has ruled that prosecutors may use the alleged gun and notebook in Luigi Mangione’s state murder trial, while suppressing some evidence seized from his backpack during his arrest at a Pennsylvania McDonald’s.

Judge Gregory Carro found that the initial warrantless backpack search crossed constitutional limits, but allowed evidence later obtained through a police inventory search, including the alleged weapon and notebook. Mangione has pleaded not guilty in the killing of UnitedHealthcare CEO Brian Thompson.

The ruling matters beyond trial procedure. The case has become a national flashpoint over how the public interprets violence tied to anger at corporations, health insurance and political grievance. AP/NORC polling after Thompson’s killing found many Americans blamed both the shooter and insurance industry practices for the climate surrounding the attack, while Pew later found 85% of U.S. adults said politically motivated violence is increasing.

Mangione’s state trial is scheduled for Sept. 8, 2026.
