Luigi Mangione, the defendant charged in the December 2024 killing of UnitedHealthcare executive Brian Thompson, has withdrawn his notice to pursue an affirmative defense of extreme emotional disturbance (EED). According to court records released last week, the defense’s move to retract the CPL 250.10 notice—which would have signaled a formal psychiatric defense—has sparked debate among legal experts regarding trial strategy and the potential for a manslaughter conviction.
Why withdraw a psychiatric defense notice?
Defense attorneys typically file a CPL 250.10 notice to inform the court and prosecution that they intend to introduce psychiatric evidence. Karen Friedman Agnifilo, representing Mangione, argued in sealed proceedings that filing this notice forces a defendant to publicly admit to the crime, which could prejudice potential jurors in both state and federal jurisdictions. By withdrawing the notice, the defense avoids the immediate requirement to share expert reports and psychiatric evaluations with the prosecution, according to transcripts unsealed by Judge Gregory Carro.
A CPL 250.10 notice is a specific New York legal procedure. Filing it grants a defendant the right to use psychiatric testimony but also mandates that they submit to a mental health evaluation by the prosecution.
Can an EED defense succeed without formal notice?
While the withdrawal of the notice suggests a shift in strategy, legal experts note it does not permanently preclude an emotional distress argument. Ron Kuby, a veteran defense attorney, points to the 2010 case of Gigi Jordan as a precedent. Jordan was found guilty of first-degree manslaughter rather than murder after her legal team successfully argued extreme emotional distress without ever filing a 250.10 notice. According to Kuby, a defendant can still testify or rely on the prosecution’s own evidence to demonstrate a state of mental unwellness to a jury.
How does the prosecution view the defense strategy?
The prosecution has expressed caution regarding the ongoing legal maneuvers. Gary Galperin, an adjunct professor at Cardozo School of Law and a former prosecutor, stated he views the withdrawal as a definitive step, suggesting the defense is unlikely to reactivate the notice. Meanwhile, Manhattan prosecutor Joel Seidemann has raised concerns regarding courtroom security, citing the consistent presence of Mangione supporters. Prosecutors have signaled they may request an anonymous jury and stricter rules on courtroom attire, such as banning pins or garments that display messages of support for the defendant.
Comparison: Formal Notice vs. Informal Defense

Follow court dockets and official filings closely. Legal strategies in high-profile cases often shift based on rulings regarding evidence admissibility, which can change the trajectory of a trial significantly.
Frequently Asked Questions
- What is an extreme emotional disturbance (EED) defense? It is a legal defense that, if accepted by a jury, can reduce a murder charge to manslaughter by arguing the defendant acted under the influence of intense emotional distress.
- Does withdrawing the notice mean Mangione cannot mention his mental health? No. According to Ron Kuby, a defendant can still present evidence of their mental state through their own testimony or other trial evidence without a formal notice.
- What happens if the jury finds EED? If a jury finds a defendant committed the act but was under extreme emotional disturbance, the verdict shifts from murder to manslaughter.
