Luigi Mangione pleaded guilty to federal stalking charges on August 14, 2026, admitting to the December 2024 shooting death of UnitedHealthcare CEO Brian Thompson in Manhattan.
The 28-year-old defendant confessed to using a 3D-printed gun with a silencer to kill Thompson, whom he targeted after learning of an investor conference via email.
Mangione was arrested five days after the shooting at a Pennsylvania McDonald's, and his legal defense fund has since raised over $1.5 million from public supporters.
