Luigi Mangione, 27, accused of killing UnitedHealthcare CEO Brian Thompson, appeared in federal court in Manhattan on Friday. His lawyers challenged the prosecution’s request for the death penalty and the evidence against him. They brought in Paresh Patel, an expert on federal stalking law, to argue that stalking is not inherently violent, questioning a key factor for seeking capital punishment, according to ABC7NY.

Mangione has pleaded not guilty to federal stalking and murder charges. The case has drawn public attention, with the Trump administration calling the killing the act of a “left-wing assassin” and some supporters connecting it to healthcare reform debates, as reported by Gothamist. Evidence, including a notebook, a map, and a bus ticket, is contested, with the defense claiming it was seized unlawfully and prosecutors saying the search was legal.

Federal prosecutor Sean Buckley said evidence taken from Mangione’s notebook was obtained through a search warrant that “was supported by ample probable cause,” stating, “The Government searched the contents of the defendant’s notebook pursuant to a judicially authorized search warrant that expressly covered, among other things, handwritten materials, including notebook entries, contained within the defendant’s backpack.” The statements were made during a three-week pretrial hearing in state court, where Mangione’s lawyers sought to exclude evidence seized from his backpack and raised claims of a conflict of interest involving Attorney General Pam Bondi’s ties to UnitedHealthcare. Prosecutors rejected those claims, saying, “There is simply no factual basis for the assertion that outside corporate interests influenced the Attorney General’s charging decision in any fashion,” as cited by ABC7NY. Moving forward, the judicial deliberations are poised to decide whether the federal murder and firearm charges will be upheld or dismissed. The judge is expected to decide whether the federal murder and firearm charges will move forward or be dismissed.
