‘I Shot Brian Thompson’: Luigi Mangione Pleads Guilty To Federal Charges In UnitedHealthcare CEO Killing

Luigi Mangione, the 28-year-old accused of assassinating UnitedHealthcare CEO Brian Thompson, pleaded guilty in Manhattan federal court on Friday to the federal charges against him – admitting that he went to New York with the intent to kill Thompson.

The plea came during an 11 a.m. hearing before U.S. District Judge Margaret Garnett, added to the calendar at the last minute this week at the joint request of prosecutors and Mangione’s defense team.

“I shot Brian Thompson,” he told Garnett.

Members of Brian Thompson’s family were present in the courtroom. Outside, a crowd of Mangione supporters gathered – a fixture of his court appearances since his arrest.

The charges

Mangione was charged with two federal counts: interstate stalking resulting in death, and stalking through the use of interstate facilities resulting in death. Each carries a maximum sentence of life in prison.

Judge Garnett dismissed a federal murder charge in January 2026 that would have carried a potential death penalty, removing capital exposure from the federal case.

A senior Justice Department official told Fox News on Thursday that “there is no deal” – meaning Mangione would be pleading guilty without a negotiated sentencing guarantee.

The plea is the latest milestone in a case that has gripped the country since December 4, 2024.

Thompson, 50, a father of two, was gunned down on a Midtown Manhattan sidewalk outside the Hilton, hours before UnitedHealth Group was set to host its annual investor conference at the hotel. After a five-day, multistate manhunt, authorities apprehended Mangione at a McDonald’s in Altoona, Pennsylvania.

Investigators recovered a manifesto criticizing the American health insurance industry – a discovery that split public reaction sharply. While many condemned the killing as a cold-blooded assassination, others treated Mangione as a dark symbol of mounting public frustration with the U.S. healthcare system.

A looming state battle

Friday’s federal plea does not close the book. Mangione still faces a parallel state prosecution in New York for second-degree murder and weapons offenses, with trial scheduled to begin next month. Earlier terrorism-related counts in the state case have been dismissed.

The federal plea is expected to trigger an immediate clash over the state trial. Mangione’s defense team is expected to argue the state case should be dismissed on double jeopardy grounds, contending he cannot be prosecuted twice for the same conduct.

“One-plus-one is two. Double jeopardy, by any common-sense definition,” he shouted during a February court appearance.

The Manhattan District Attorney’s Office has signaled strong opposition, arguing the federal and state charges address distinct legal harms. Legal experts have called the question genuinely open. “It is incredibly complicated,” defense attorney Paul Shechtman told the New York Times earlier this month about New York’s double jeopardy statute.

Retired NYPD inspector Paul Mauro suggested a plea without a deal could still serve Mangione: “He gets to serve his time in federal prison, where conditions are better, and he is hoping that the New York state double jeopardy law will knock out the state case.”
