L
uigi Mangione, arrested in connection with the murder of UnitedHealthcare CEO Brian Thompson in New York City, comes from a wealthy Maryland family. His grandfather, Nicholas Mangiano, built a real estate empire including country clubs and media outlets. Mangiano passed away in 2008 at 83 after developing Turf Valley Resort, Hayfields Country Club, and WCBM-AM radio station.

    The family's patriarch had 10 children and was married to Mary until her death in 2013. Luigi is related to Republican Maryland House of Delegates member Nino Mangione and his sister MariaSanta is a medical resident at UT Southwestern Medical Center. Currently detained in Pennsylvania, Luigi was arrested at McDonald's on firearm charges after staff alerted authorities.

    Police discovered him with a suspected 3D-printed 'ghost gun', silencer, and false identification matching one used at an NYC hostel. A manifesto expressing grievances about healthcare industry profits was also found. Despite his privileged background, Mangione developed anti-capitalist views and previously worked as a software engineer at TrueCar until February 2023.

    The investigation continues into the December 4 shooting of Thompson outside Manhattan's Hilton Hotel, where shell casings were marked with "deny," "defend," and "depose."
