Luigi Nicholas Mangione (born May 6, 1998) is an American man charged with the murder of Brian Thompson, the CEO of UnitedHealthcare, who was shot and killed outside a Manhattan hotel on December 4, 2024. After a five-day nationwide manhunt, he was arrested at a McDonald's in Altoona, Pennsylvania, on December 9, 2024. Both federal and New York state prosecutors have brought charges against him; Attorney General Pam Bondi directed her office to seek the death penalty on the federal side.

Mangione comes from a prominent Baltimore family and graduated from the University of Pennsylvania with degrees in engineering. He's pleaded not guilty to all charges. Since his arrest, he's become a polarizing figure: supporters have cast him as a folk hero protesting America's healthcare system, while prosecutors describe the killing as premeditated murder.

Summary

The Thompson killing became one of the most heavily covered criminal cases in recent American history. It sparked intense debate about the U.S. healthcare system and corporate accountability. On the morning of December 4, 2024, Thompson, 50, was shot multiple times outside the New York Hilton Midtown as he walked toward the hotel where UnitedHealthcare's annual investor conference was scheduled. The gunman fled on foot, then by bicycle, rode through Central Park, and vanished from the city.

The shell casings left at the scene bore three words: "delay," "deny," and what appeared to be "depose." These terms have long been associated with insurance industry tactics to reject or postpone legitimate claims. When police arrested Mangione, they recovered a three-page handwritten document expressing anger at what he'd characterized as a corrupt healthcare system prioritizing profits over patients.

The case has become a flashpoint in American political discourse. Supporters raised over $900,000 for his legal defense by mid-April 2025. Comparisons to historical acts of political violence emerged, raising questions about public anger toward the healthcare industry.

Background

Early Life and Family

Mangione was born on May 6, 1998, in Towson, Maryland, to Kathleen (née Zannino) and Louis Mangione. He grew up in a wealthy family with deep roots in Baltimore's Italian American community. His paternal grandfather, Nicholas Mangione, was the son of poor Italian immigrants who built a substantial business empire. This included country clubs, an assisted living company, and a conservative radio station.

The family owns the Turf Valley Resort in Ellicott City, Maryland, and Hayfields Country Club in Hunt Valley, Maryland. They also run a charitable foundation with nearly $4.5 million in assets and have long supported Loyola University Maryland, which named its aquatic center after them. One of Mangione's cousins, Nino Mangione, serves in the Maryland House of Delegates.

Education

He attended the Gilman School, an elite all-boys college preparatory institution in the Baltimore region where tuition today runs close to $40,000 annually. At Gilman, he played soccer, ran track, competed in cross country, and wrestled. A passion for video games and coding developed early. He taught himself to program and co-founded a gaming app development company while still in high school. Mangione graduated as valedictorian in 2016, delivering a commencement speech on artificial intelligence and technology's impact on society.

At the University of Pennsylvania, he earned bachelor's and master's degrees in engineering with a computer science focus, completing his studies in May 2020. During his freshman year, he started a video game development club that grew to over 50 members. In a 2017 interview with the campus newspaper, he spoke about trying to move away from the university's competitive culture by making the club open to everyone.

Career and Health Issues

After graduating, Mangione worked as a data engineer at TrueCar, Inc., an online car marketplace, starting in November 2020. He left the company in 2023. College wasn't the end of his wandering; he moved to Hawaii and lived at Surfbreak, a co-living space, while working remotely. Hiking, stargazing, and reading filled his free time.

Things changed when he suffered a serious lower back injury while surfing. The injury worsened over time. Friends said his chronic pain increasingly isolated him and likely contributed to growing frustration with the healthcare system. By the months before the shooting, he'd withdrawn from friends and family. Some people said they'd lost contact with him entirely.

The Shooting and Manhunt

Murder of Brian Thompson

December 4, 2024, started like any other morning for Brian Thompson. The 50-year-old UnitedHealthcare CEO was walking toward the New York Hilton Midtown in Midtown Manhattan, where the company's annual investor conference was scheduled. At approximately 6:45 a.m., a masked gunman approached from behind and fired multiple times with a pistol equipped with a suppressor. Thompson was taken to Mount Sinai West hospital, where he was pronounced dead.

The shooter fled on foot, then by bicycle, riding into Central Park before vanishing. Surveillance footage captured images at various points: outside a nearby Starbucks, at a hostel on the Upper West Side where he'd stayed under a false name. Shell casings at the scene bore inscriptions: "delay," "deny," and what appeared to be "depose." These terms are associated with insurance claim denial practices.

Arrest in Pennsylvania

A nationwide manhunt began. The NYPD released surveillance images and offered a reward for information.

Five days later, on December 9, 2024, the manager at a McDonald's in Altoona, Pennsylvania, recognized Mangione from the widely circulated photographs. Staff called police. Over the phone, the manager said a man in their restaurant "looks like the CEO shooter." Officers found Mangione wearing a mask similar to one seen in surveillance footage and carrying a fraudulent New Jersey ID, a 3D-printed "ghost gun" with a suppressor believed to be the murder weapon, and a three-page handwritten document expressing grievances against the healthcare industry.

He was arrested and held at SCI-Huntington, a high-security Pennsylvania state facility, before being transferred to federal custody.

Charges and Legal Proceedings

A New Yorker report in April 2026 listed Mangione among recent residents of 4 North, the high-security unit at MDC Brooklyn where the facility houses its most notable pretrial detainees.

State Charges

Manhattan District Attorney Alvin Bragg initially charged Mangione with second-degree murder, criminal possession of a weapon, and forgery. But the charges didn't stop there. They were upgraded to include first-degree murder in furtherance of terrorism and second-degree murder as a crime of terrorism, based on what prosecutors said was his intent to intimidate the public and influence corporate policy through violence.

In September 2025, Judge Gregory Carro dismissed the two terrorism-related murder charges. He ruled they didn't meet the legal threshold for acts intended to intimidate or coerce the public. Still, Mangione faces the second-degree murder charge in the state case, which carries a potential sentence of 25 years to life.

Federal Charges

A federal grand jury indicted him on charges including murder of a United States citizen, stalking, and use of a silencer in a crime of violence. Early in 2025, Attorney General Pam Bondi directed federal prosecutors to seek the death penalty, making this one of the most high-profile federal death penalty cases in recent years. The Department of Justice defended the decision in a November 2025 court filing.

Defense Strategy

His defense attorneys have filed motions to suppress evidence collected during his arrest. They argue that Altoona police improperly seized items from his backpack and questioned him before reading his Miranda rights. As of November 2025, he hadn't received a laptop to review discovery materials, despite a judge's ruling that he could have one in jail.

Public Response

The killing triggered an extraordinary public response. Many condemned the murder. Others expressed sympathy for what they saw as an act of protest against a healthcare system that denies coverage and prioritizes profits. Social media posts celebrating Mangione spread rapidly, and a website soliciting donations for his defense raised more than $900,000 by mid-April 2025.

This case became a focal point for debates about healthcare policy, income inequality, and public frustration with large corporations. Commentators drew parallels to historical cases of political violence while noting the unusual degree of public sympathy for an accused murderer.

Terminology
