Luigi Mangione, the man charged with the December 2024 fatal shooting of UnitedHealthcare CEO Brian Thompson in midtown Manhattan, will assert during his trial that he acted under extreme emotional disturbance.
Judge Gregory Carro disclosed on Wednesday that Mangione’s legal team informed the court of their intent to argue that their client was in a state of “extreme emotional disturbance” during the alleged act.

The shooting occurred in December 2024 outside a Manhattan hotel, a crime that stunned the nation and amplified public frustration over inflated healthcare costs. A surveillance video of the incident circulated widely online.
Mangione’s defense team will rely on New York’s legal provision allowing murder defendants to claim extreme emotional disturbance, which could result in a manslaughter conviction and reduced sentencing. This differs from an insanity plea, which would classify him as unfit for trial and lead to psychiatric confinement.
Prosecutors have alleged that the words “deny” were written on the bullet casing used in the shooting, symbolizing allegations of corporate negligence by health insurers. If convicted of manslaughter, Mangione could avoid the potential death penalty under federal charges, which were partially dismissed earlier this year by U.S. District Judge Margaret Garnett.
Mangione, a 28-year-old who has previously pleaded not guilty to both state and federal charges related to the killing, is scheduled to stand trial in state court on September 8. A separate federal trial, including charges of stalking and obstruction, will begin October 13. A conviction in either case could result in life imprisonment.
