NEW YORK (AP) — The pretrial hearing of Luigi Mangione wrapped up recently, with a judge poised to make a pivotal ruling in May regarding the evidence prosecutors can use against him in the murder trial of UnitedHealthcare CEO Brian Thompson. Prosecutors have presented testimonies from nearly 20 witnesses over the past three weeks, including police involved in Mangione's December 2024 arrest in Pennsylvania. Mangione's lawyers, however, chose not to call any witnesses. A significant aspect of the case revolves around whether items found in Mangione's backpack—such as a gun believed to match that used in the murder, and a notebook referencing an intention to ‘wack’ an executive—can be admitted. Mangione's defense challenges the legality of the search that led to their discovery, arguing it lacked a warrant. This case has significant implications, with Mangione facing charges in both state and federal courts and pleading not guilty to all charges.
