Luigi Mangione, a 26-year-old from a prominent Maryland family, has been arrested and charged with the murder of UnitedHealthcare CEO Brian Thompson. Mangione, who graduated from the University of Pennsylvania and worked as a data engineer, allegedly shot Thompson outside a hotel in New York City. He is being held without bail and faces federal charges, including murder and stalking, with prosecutors seeking the death penalty. Mangione's motivations are unclear, but he had expressed resentment towards the healthcare industry and had struggled with chronic back pain.
