Luigi Mangione pleads guilty to federal charges in the killing of UnitedHealthcare CEO




By Frederick H. Lowe

Luigi Mangione, who was considered by some to be a celebrity after shooting down and killing Brian Thompson, UnitedHealthcare CEO, today pleaded guilty to federal stalking charges that led to Thompson’s murder. 
He made the admission in front of Thompson’s mother, who was seated in the gallery along with several UnitedHealthcare executives. 

Mangione, 28, revealed through his allocution to the court that he posed as a potential investor to confirm the location of the investors’ conference so he could track Thompson’s location. 

Mangione was charged with two federal counts — interstate stalking resulting in death and stalking through use of interstate facilities resulting in death. The charges carry a maximum penalty of life in prison and are separate from the state allegations, which include second-degree murder and firearms crimes.

He told the judge that he was motivated to kill Thompson because of his experience with the healthcare system as a patient with a back injury, which made him a hero in the eyes of many who were angry and upset with the nation’s health care system. Mangione also received many marriage proposals from admiring young women.

Mangione faces a maximum sentence of life in prison. He will be sentenced at a separate hearing on Dec. 18. He also faces state murder charges.

Mangione’s federal plea raised questions about the state murder trial, scheduled to begin on September 8, 2026. His defense has argued that the federal guilty plea could invoke New York’s double jeopardy protections, potentially barring the state prosecution for the same conduct.

However, Manhattan District Attorney Alvin Bragg’s office has stated it will contest any motion to dismiss, arguing that the federal stalking charges and state murder charges involve different legal elements and harms, and therefore double jeopardy should not prevent the state trial. 

Mangione was arrested at a Pennsylvania McDonald’s on Dec. 9, 2024, five days after Thompson was fatally shot outside the Hilton Hotel in Manhattan on Wednesday (BlackmansStreet.Today, December 19, 2024).

Mangione’s gun jammed, but he quickly fixed it before firing more bullets, two of which struck Thompson.
Authorities reported that a masked gunman approached Thompson outside the hotel and fired at close range before fleeing into Central Park on an electric bicycle. 

Thompson’s estranged wife disclosed that he had been receiving threats before his death, but the motive for the shooting initially remained unclear. Mangione later admitted that he was upset with the health care system. He also told the judge that he was motivated to kill Thompson because of his experience with the healthcare system after a back injury. A backpack believed to belong to the suspect in the killing was found in Central Park on Friday after the killing, a law enforcement official said. Inside, police found Monopoly money and a Tommy Hilfiger jacket, according to officials briefed on the matter.

Among the pieces of evidence found by authorities in Mangione’s backpack was a notebook that detailed his apparent grievances against the industry. At the scene, authorities found a bullet and two shell casings that had the words “delay,” “deny,” and “depose” written on them.

Mangione was not the usual poor, homeless suspect police love to beat up and charge with resisting arrest. 
Mangione, 26, holds both a Bachelor’s and a Master’s degree in computer science from the University of Pennsylvania. 
He also gained recognition as the valedictorian at Gilman School, a private all-boys school in Baltimore. The school charges $40,000 a year for tuition.His work includes contributions to machine learning and robotics.

He was born and raised in Maryland, has ties to San Francisco, and his last known address is in Honolulu, Hawaii, Chief of Detective Joseph Kenny said at a news briefing.

Mangione is from a prominent Maryland family that owns country clubs, healthcare facilities, and real estate companies, CBS News reported. He’s also a cousin of Maryland state delegate Nino Mangione, who represents parts of Baltimore County.

But he was arrested while eating like a commoner.He was picked up while eating at a McDonald’s restaurant in Altoona, Pennsylvania. 

A restaurant employee recognized Mangione’s photo and called the cops, the NYPD chief of detectives said.
