Luigi Mangione’s lawyers are urging a judge to bar federal prosecutors from seeking the death penalty in the killing of UnitedHealthcare CEO Brian Thompson. They argued in court papers Saturday that authorities prejudiced his case by turning his arrest into a “Marvel movie” spectacle and by publicly declaring their desire to see him executed. Fresh from a legal victory that eliminated terrorism charges in Mangione’s state murder case, his lawyers are now fighting to have his federal case dismissed. They cited U.S. Attorney General Pam Bondi’s declaration prior to his April indictment that capital punishment is warranted for a “premeditated, cold-blooded assassination that shocked America.” Federal prosecutors have until Oct. 31 to respond. Mangione has pleaded not guilty.
