On December 4, 2024, UnitedHealthcare CEO Brian Thompson was fatally shot outside the New York Hilton Midtown in what prosecutors allege was a premeditated attack by Luigi Mangione, a 26-year-old University of Pennsylvania graduate. Mangione was arrested five days later at a McDonald's in Altoona, Pennsylvania, after a nationwide manhunt, and charged with second-degree murder in New York state court and stalking charges in federal court. As of April 2026, Mangione has pleaded not guilty to all charges; his state trial is scheduled to begin September 8, 2026, and his federal trial is set for October 2026, with a federal judge having ruled that prosecutors cannot seek the death penalty.
