Judge Gregory Carro ruled Monday that a gun found in Luigi Mangione's backpack can be used as evidence in his murder trial [1].
The decision strengthens the prosecution's ability to link Mangione to the killing of UnitedHealthcare CEO Brian Thompson. By allowing the weapon into evidence, the court enables the state to present a more complete physical chain of evidence connecting the defendant to the crime.
The ruling took place in a New York state court on May 18, 2026 [1], [2]. Judge Carro said the gun is admissible because it is relevant to linking Mangione to the murder [1], [2]. This legal determination follows the arrest of Mangione in 2024 [4].
The case has drawn significant attention due to the profile of the victim and the nature of the evidence recovered. The gun was discovered within a backpack belonging to Mangione, and the court's decision ensures that this specific piece of evidence will not be excluded from the proceedings on the grounds of admissibility.
Legal representatives for the defense and prosecution have been navigating the admissibility of various items recovered during the investigation. The inclusion of the weapon is a pivotal step in the preparation for the trial, as it provides a direct physical link between the suspect and the act of violence.

The admissibility of the firearm removes a significant hurdle for the prosecution, as physical evidence is often the cornerstone of a murder conviction. By ruling the gun relevant, the court has shifted the momentum toward the state, forcing the defense to either challenge the origin of the weapon or provide an alternative explanation for its possession.
