Case file Luigi Mangione, reference D C zero zero two two. According to the U.S. Department of Justice, a criminal complaint was unsealed on December nineteenth, twenty twenty-four, charging Luigi Nicholas Mangione, then twenty-six, of Towson, Maryland, in connection with the December fourth killing of UnitedHealthcare executive Brian Thompson in Midtown Manhattan. The Justice Department said the federal complaint included firearm, stalking, and silencer-related counts, and said a complaint is only an allegation and defendants are presumed innocent unless proven guilty. The Associated Press reported that New York Judge Gregory Carro later dismissed state terrorism charges, while keeping other charges, including second-degree murder. CBS News New York reported that U.S. District Judge Margaret Garnett dismissed federal firearms charges that had carried a possible death penalty, while leaving stalking charges that can carry life in prison. AP reported prosecutors would not appeal the death-penalty ruling. AP reported Mangione has pleaded not guilty to state and federal charges. The state trial is scheduled for September eighth, twenty twenty-six, and federal jury selection for January fifth, twenty twenty-seven.
