Accused healthcare CEO killer Luigi Mangione on Thursday withdrew his plans to pursue a psychiatric defense at his upcoming New York murder trial in the fatal shooting of UnitedHealthcare CEO Brian Thompson.
“The defense respectfully withdraws CPL 250.10 notice at this time,” Mangione’s attorney, Karen Agnifilo, wrote in a letter filed with Manhattan Supreme Court Judge Gregory Carro. The decision comes one day after his legal team informed the court of their plans to present this defense at trial.
The latest filing means that, for now, Mangione no longer intends to argue he was acting under an “extreme emotional disturbance” when prosecutors say he gunned down Thompson on a Midtown Manhattan sidewalk in December 2024. His state criminal trial, one of three cases he faces, is currently slated to begin on Sept. 8.
The unusual New York defense tactic, available only in murder cases, can reduce a murder conviction to first-degree manslaughter if a jury concludes the defendant acted while suffering from severe emotional distress and had a reasonable explanation for that condition. A successful defense would have reduced Mangione’s possible sentence exposure from life imprisonment to a maximum of 25 years.
But the strategy would also have effectively required Mangione to concede that he committed the shooting while arguing that his mental state mitigated his criminal responsibility.
Legal experts suggested the unusual defense could have brought broader debates over the U.S. healthcare system into the trial. Prosecutors with Manhattan District Attorney Alvin Bragg‘s office have alleged Mangione harbored deep hostility toward UnitedHealthcare, writing in journals that the company “literally extracts human life force for money” and describing it as emblematic of problems within the American healthcare system.
Authorities have also alleged that ammunition recovered from the scene bore inscriptions reading “delay,” “deny,” and “depose,” which prosecutors contend referenced criticisms commonly leveled against health insurers.
LUIGI MANGIONE TO ASSERT PSYCHIATRIC DEFENSE IN MURDER TRIAL
Mangione’s decision to abandon the defense may also avoid complications that would have arisen in his separate federal prosecution stemming from Thompson’s death. He also faces charges in Pennsylvania, where he was ultimately arrested in December 2024, related to his alleged possession of an unlicensed firearm.
Unlike New York law, federal courts do not recognize an extreme emotional disturbance defense. Any admission by Mangione that he committed the shooting during the state trial could have been used against him in the federal case, which is scheduled to proceed next year after the state prosecution.
