Judge Weighs Suppression of Key Evidence in UnitedHealthcare CEO Killing Case

The rulings could reshape a case that now proceeds without terrorism charges.

Overview

  • Evidentiary hearings opened Monday before Judge Gregory Carro in Manhattan to determine whether police‑seized items and arrest statements can be used at trial.
  • The defense argues the Pennsylvania backpack search and custodial questioning were unconstitutional, citing a lack of a warrant and inadequate Miranda warnings.
  • Prosecutors from District Attorney Alvin Bragg’s office contest the challenge and seek to admit items police say were in the backpack, including a 3D‑printed gun, a silencer, electronic devices, and notes.
  • Testimony is expected to run through the week with officers and other witnesses, and the judge’s decisions could affect the scope and timing of upcoming trials.
  • Luigi Mangione has pleaded not guilty in state and federal cases, remains in federal custody in Brooklyn, and faces a potential death‑penalty bid by federal prosecutors after terrorism counts were tossed in September; a small group of supporters gathered outside court.
