As the anniversary of the killing of UnitedHealthcare CEO Brian Thompson nears, the legal team for suspect Luigi Mangione is challenging the admissibility of crucial evidence. In a New York court hearing, defense attorneys argued to suppress a gun, a silencer, and handwritten notes that were seized during Mangione's arrest in Pennsylvania shortly after the December 4, 2024, shooting.
The defense's motion hinges on the claim that the evidence was obtained through an unlawful search. They contend that police in Altoona, Pennsylvania, lacked sufficient cause to detain and question Mangione at a McDonald's on December 9. According to his lawyers, this alleged violation of his constitutional rights makes all evidence gathered from that point onward, including the contents of his backpack, inadmissible in court.
Prosecutors firmly reject this claim, asserting the stop was lawful and the items are central to their case. The discovered evidence includes an untraceable "ghost gun" believed to be the murder weapon. Central to the dispute are handwritten documents, which prosecutors have characterized as a manifesto detailing grievances against the healthcare industry. The defense, however, refers to the documents as a private journal. Mangione has pleaded not guilty to murder and weapons possession charges.
Thompson was fatally shot from behind in Midtown Manhattan while on his way to an investors' conference. The high-profile killing prompted an intense manhunt ending with Mangione's capture. The fallout from the brazen attack has been felt across the insurance industry, with some companies removing executive biographies and photos from their websites citing safety concerns. The initial arrest in Pennsylvania followed a police tip that led officers to Mangione, who was carrying the contested items. A judge is expected to rule on the evidence suppression motion in the coming weeks, a decision that will significantly shape the future of the trial.
