Luigi Mangione: Brian Thompson's Shooter Hails from Wealthy Family and Is Heir to Holiday Resort Fortune and His Sister Is a Top Doctor

He attended the prestigious all-boys Gilman School, which costs around $40,000 annually, from sixth grade through his senior year.

The man accused of killing UnitedHealthcare CEO Brian Thompson hails from an affluent family in Maryland, well-known in their local community, and is even related to a state legislator. Luigi Mangione, 26, grew up in the picturesque Baltimore suburb of Towson, and is the heir to a holiday resort fortune created by his grandparents.

His super rich family is rooted in the legacy of his late grandfather, Nicholas Mangione. A first-generation American, Nicholas built a real estate empire in the state, which includes country clubs and media ventures. The Mangione family owns two expansive country clubs: the Turf Valley Resort in Ellicott City and the Hayfields Country Club in Cockeysville.

On Monday, he was arrested at a McDonald's in Altoona, Pennsylvania—a small rural city in the state's center—after an employee recognized him from wanted posters and alerted authorities.

When officers arrived and requested his identification, he reportedly presented a fake ID. This same ID had allegedly been used to check into a New York City hostel prior to the execution-style killing on December 4.

According to law enforcement sources, he was also carrying a firearm, three more fake IDs, and a manifesto criticizing authority with statements such as "these parasites simply had it coming."

"Here on campus, our focus will remain on caring for and educating the boys. Thank you for your understanding," they added.
