Accused UnitedHealthcare CEO Assassin Seeks to Suppress Backpack Evidence in New York Case

Defense lawyers for 27‑year‑old Luigi Mangione, accused of assassinating UnitedHealthcare CEO Brian Thompson outside a Manhattan hotel on Dec. 4, 2024, have filed a fresh motion in New York state court to throw out evidence taken from his backpack after his arrest in Altoona, Pennsylvania. Prosecutors say the bag yielded the suspected murder weapon and a manifesto attacking the health insurance industry, but the defense argues Altoona police conducted multiple warrantless searches over about eight hours, falsely invoking bomb concerns as a pretext, selectively inventoried contents, and read Mangione’s journals before obtaining a warrant. Attorney Karen Friedman Agnifilo’s filing contends that because officers quickly realized they were holding a suspect in a New York assassination case, New York search‑and‑seizure rules should apply and that later station‑house searches were also improper. One officer is alleged to have ensured her body‑camera audio was on before opening the compartment where the gun was found, which the defense frames as evidence of an evidentiary fishing expedition rather than a safety check. The motion follows a similar suppression effort that failed in federal court in January, and Judge Gregory Carro will now decide whether this backpack evidence can be used when Mangione goes to trial on June 8 in a case that has drawn national attention to interstate policing and defendants’ Fourth Amendment rights.

📌 Key Facts

  • Luigi Mangione is charged with fatally shooting UnitedHealthcare CEO Brian Thompson in the back outside a Manhattan hotel on Dec. 4, 2024.
  • He was arrested in Altoona, Pennsylvania, after being recognized from an NYPD wanted poster at a McDonald’s, and police seized his backpack.
  • The new state‑court motion claims Altoona police searched the bag multiple times over roughly eight hours before getting a warrant, used a bomb‑safety rationale as pretext, read journals, and failed to list non‑evidentiary items, tainting what prosecutors say is the murder weapon and a manifesto.
  • Defense lawyers argue New York search‑and‑seizure standards govern because the case is being tried in Manhattan and Altoona officers quickly coordinated with NYPD.
  • A similar suppression bid was rejected in federal court in late January, but Judge Gregory Carro must now rule in the New York state prosecution ahead of the June 8 trial.
