Luigi Mangione won’t assert a psychiatric defence in state trial, after all, his lawyers say
Luigi Mangione, the 28-year-old accused of murdering UnitedHealthcare CEO Brian Thompson, has withdrawn his intent to pursue an “extreme emotional disturbance” defense in his upcoming state murder trial. According to a letter filed by his legal team on Thursday, the defense will no longer assert the psychiatric claim, a move that follows a deadline set by Manhattan Judge Gregory Carro. Mangione, an Ivy League graduate, continues to plead not guilty to both state and federal charges related to the December 2024 killing.
Why did the defense withdraw the psychiatric claim?
The defense team, led by attorney Karen Friedman Agnifilo, submitted a letter to Judge Carro stating they “respectfully withdraws” the notice under New York’s psychiatric defense statute “at this time.” This decision came just one day after the defense had initially signaled plans to argue that Mangione suffered from extreme emotional disturbance during the Dec. 4, 2024, shooting. By abandoning this strategy, the defense avoids the immediate requirement to provide prosecutors with supporting evidence, a deadline they were facing on Thursday.
An “extreme emotional disturbance” defense is not the same as a “not guilty by reason of insanity” plea. If a jury accepts an emotional disturbance claim, it does not absolve the defendant of the crime; instead, it can reduce a murder conviction to manslaughter, which carries a maximum sentence of 25 years rather than potential life imprisonment.
How does this shift impact the upcoming trials?
Mangione faces a complex legal path with separate proceedings in state and federal courts. His state murder trial is scheduled to begin Sept. 8, while his federal trial, which centers on stalking and firearms charges, is set for Oct. 13. According to Friedman Agnifilo, the decision to withdraw the defense was influenced by concerns that disclosing psychiatric materials in the state case would be “prejudicial” to the federal case, where an emotional disturbance defense is not permitted.
Case Comparison: State vs. Federal Charges
| Charge Type | Key Focus | Defense Status |
|---|---|---|
| State Murder | Killing of Brian Thompson | Psychiatric defense withdrawn |
| Federal | Stalking and firearms | Not applicable |
What is the status of the evidence?
Prosecutors have successfully moved to include key physical evidence in the state trial. Last month, Judge Carro ruled that a gun and a notebook linked to the defendant by investigators can be used as evidence. According to prosecutors, the 3D-printed pistol recovered during the investigation matches the weapon used in the shooting of Thompson, who was killed while walking to an investor conference in Manhattan.
