Luigi Mangione's legal team withdrew a psychiatric defense just one day after announcing it for his upcoming state trial in the December 2024 killing of UnitedHealthcare CEO Brian Thompson. The defense had planned to argue that Mangione was suffering from an extreme emotional disturbance at the time of the shooting, which could have potentially reduced his murder charge to manslaughter.

Mangione appeared in court on Wednesday after a one-day delay caused by prosecutors' failure to serve the order for his appearance. Judge Gregory Carro took responsibility for the paperwork error that led to the postponement from Tuesday's scheduled hearing. Mangione faces both state and federal charges, with his state trial set to begin September 8 and jury selection in his federal interstate stalking trial beginning in October.

The defense team had argued that an extreme emotional disturbance could have reduced the murder charge to manslaughter, potentially resulting in a shorter prison sentence. Legal experts noted that this psychiatric defense would effectively admit to killing Thompson with mitigating circumstances, differing from an insanity plea which seeks total absolution. If convicted of manslaughter instead of murder, Mangione could face up to 25 years in prison rather than the potential life sentence for murder.

In May, Judge Gregory Carro ruled that a police search of Mangione was 'improper' and 'warrantless,' suppressing some items found in his backpack as evidence. However, he allowed a gun and notebook discovered during a subsequent search at a police station to be used. The reasons for Wednesday's hearing remain unknown as Judge Carro scheduled it in June and closed the conference to the public and press at the defense team's request.

Legal experts have differing opinions on whether Mangione's team will pursue any psychiatric defense. Gary Galperin, adjunct professor at Cardozo School of Law and former prosecutor, believes they will not. However, Ron Kuby, a veteran defense attorney, explained that withdrawing the CPL 250.10 notice does not necessarily mean abandoning a psychiatric defense. The defendant can still present evidence of extreme emotional disturbance without filing the notice.

Prosecutors have expressed concerns about Mangione supporters attending court proceedings and potentially making threats. They may ask Judge Carro to impanel an anonymous jury to ensure a fair trial.
