Judge rules gun and writings are admissible in Luigi Mangione's New York murder trial

May 18, 2026

A New York judge has issued a mixed ruling on evidence admissibility in Luigi Mangione's murder trial for the December 2024 killing of UnitedHealthcare CEO Brian Thompson. Judge Gregory Carro suppressed certain items seized during what he deemed an unlawful warrantless search at a Pennsylvania McDonald's, including a magazine, cellphone, passport, wallet, and computer chip. However, the judge allowed prosecutors to present crucial evidence discovered later at the police station, specifically a handgun and notebook found in Mangione's backpack.

What action is being taken

The state murder trial is proceeding with the evidence ruling now established. Mangione's defense team continues to represent him as he maintains his not guilty plea to charges including second-degree murder, firearms charges, and stalking.

Why it matters

This ruling significantly shapes what a jury will see during Mangione's murder trial by determining which evidence can be presented. While the defense successfully excluded some evidence obtained through what the judge found to be an improper warrantless search, prosecutors retain access to the most critical evidence—the alleged murder weapon and Mangione's writings—which could prove decisive in establishing guilt or innocence. The decision balances constitutional protections against unlawful searches with law enforcement's ability to prosecute a high-profile murder case that garnered nationwide attention.

What's next

The state trial is expected to start in September.
