A New York judge will allow a gun and writings found in Luigi Mangione's backpack after his 2024 arrest to be presented at his state murder trial over the killing of UnitedHealthcare CEO Brian Thompson, but has ruled that other items are inadmissible. Judge Gregory Carro ruled on Monday that certain evidence must be suppressed, including the magazine, cellphone, passport, wallet and computer chip found with Mangione at a Pennsylvania McDonald's. Carro stated that this evidence was recovered as part of an improper and warrantless search of the then-26-year-old. However, prosecutors will be allowed to present items found during a search at a police station, including a gun and a notebook. Carro also ruled that some of Mangione's questioning by the officers who initially encountered him at the Pennsylvania fast food restaurant must be excluded from trial, particularly regarding Mangione's deceptive statements about his identity. Yet, evidence from later questioning when Mangione was in custody will be admissible. Mangione faces serious charges, including second-degree murder and several firearm violations, and he has entered a not guilty plea. The trial is expected to begin in September 2026.
