Luigi Mangione's attorneys filed a one-sentence letter on June 18, 2026, withdrawing the CPL 250.10 notice that would have allowed an extreme emotional disturbance defense at his state murder trial. The letter stated the defense would not provide the required notice at this time. The withdrawal came one day after the same court had disclosed that the defense intended to pursue the claim.
Background on the Case Prosecutors allege Mangione shot UnitedHealthcare CEO Brian Thompson outside the New York Hilton Midtown hotel on December 4, 2024. A successful extreme emotional disturbance defense under New York law would reduce a murder conviction to manslaughter and cap the maximum sentence at 25 years.
Mangione's state trial is scheduled to begin September 8, 2026. He also faces separate federal charges set for proceedings next year, where the extreme emotional disturbance defense is not available.
The defense can no longer call mental health experts, introduce psychiatric records, or present evidence of any mental health condition. An experienced defense attorney told The New York Post that the team remains free to argue extreme emotional disturbance but without supporting medical testimony.
" — Karen Agnifilo, attorney for Luigi Mangione, June 18, 2026 (court filing). Mangione faces additional charges in Pennsylvania from his December 2024 arrest on allegations of possessing an unlicensed firearm. The source materials do not state a reason for the withdrawal of the notice.
