In brief
In a courtroom in Manhattan, Luigi Mangione, 28, pleaded guilty to federal charges of cross‑state stalking resulting in death after shooting UnitedHealthcare CEO Brian Thompson on December 4, 2024. Mangione told the judge he crossed state lines armed with a 3‑D‑printed, silenced firearm, driven by pain from a broken back and a belief that the CEO was responsible for his suffering. He will face life in federal prison with no parole, while his defense seeks to invoke double‑jeopardy to halt the pending New York state case. The family of the slain executive has called the federal plea a step toward justice, but prosecutors plan to pursue the state charges anyway.
In a Manhattan federal courtroom, Luigi Mangione, 28, admitted he shot UnitedHealthcare chief‑executive Brian Thompson on December 4, 2024, and pleaded guilty to interstate stalking resulting in death. Mangione told the judge “I shot Mr Thompson in Manhattan and he died.” He explained that he crossed state lines with a 3‑D‑printed gun fitted with a silencer, intending to kill the CEO because of chronic pain and frustration at the healthcare system. The shooting occurred as Thompson entered a Midtown hotel for a company investor conference.
Mangione faces a maximum sentence of life in federal prison, with the sentencing scheduled for December 18. He has also been charged in New York state for second‑degree murder, possession of a forged instrument and multiple counts of weapon possession, but his attorneys are arguing that the federal plea should preclude the state case under the double‑jeopardy clause. The Manhattan District Attorney’s office has said it will proceed with the state prosecution regardless.
[The family of the slain CEO] said the federal judgment was a step toward justice, but stressed that they still seek a severe sentence, with prosecutors recommending 24–30 years. Judge Margaret Garnett noted the recommendation is non‑binding and that the maximum penalty is life imprisonment with no parole.
Mangione appeared in court wearing a beige prison uniform, gave a forward‑looking statement, and claimed the plan to shoot was deliberate and pre‑meditated. He noted he had emailed UnitedHealthcare claiming to be an investor, and that the intent was to kill Thompson on the morning of December 4.
