A New York judge ruled Luigi Mangione’s lawyers can pursue a state psychiatric defense, saying he may have been suffering from extreme emotional disturbance when he killed UnitedHealthcare CEO Brian Thompson. If accepted, it could shift the case from murder to
Luigi Mangione sat through court on Wednesday without showing much reaction as Judge Gregory Carro spoke. The 28-year-old—dressed in a blue suit between his lawyers—was hearing a decision that could reshape how jurors evaluate his killing of UnitedHealthcare CEO Brian Thompson.
Carro said Mangione’s attorneys informed him they plan to argue that, at the time of the killing, he was suffering from “extreme emotional disturbance.” The judge said that if the defense succeeds, Mangione could be sent to a psychiatric treatment facility instead of prison.
Carro’s ruling also set off a stark sentencing math for the state case. A jury that accepts an emotional disturbance defense would be obligated to convict Mangione of manslaughter. which carries a maximum sentence of 25 years in prison. rather than murder. A murder conviction could leave him behind bars for the rest of his life. Carro also noted that an emotional disturbance defense is not available in Mangione’s federal case. where he faces a possible life sentence.
The judge announced the plan for the defense in open court Wednesday. two weeks after holding a secret hearing on the matter. Carro said he will unseal a transcript and other records from that proceeding once redactions are made. He said the defense had requested that the hearing be sealed so lawyers could decide whether to pursue the argument and determine “the nature of that defense.”.
Carro said he did not expect the development to delay the trial, which is scheduled to begin with jury selection on Sept. 8. His next pretrial hearing is set for Aug. 11.
As the courtroom weighed what comes next, prosecutors pushed for something different. Assistant District Attorney Joel Seidemann said he wants Mangione evaluated by a prosecution psychiatrist. To make that possible. Carro said Mangione could soon be moved to New York City’s Rikers Island jail complex from a federal jail in Brooklyn. where he has been held since shortly after his December 2024 arrest.
Mangione has pleaded not guilty to state and federal charges in the Dec. 4, 2024, killing. His federal trial—covering stalking charges—begins Oct. 13.
The case turns on what happened in Manhattan on the morning Thompson was killed as he walked to a Manhattan hotel for UnitedHealth Group’s annual investor conference. Police say surveillance video shows a masked gunman shooting Thompson from behind. Investigators also said the ammunition was marked with the words “delay. ” “deny” and “depose. ” mimicking phrasing used to describe how insurers avoid paying claims.
Five days later, Mangione was arrested at a McDonald’s in Altoona, Pennsylvania, about 230 miles (about 370 kilometers) west of Manhattan. Carro’s decisions have already shaped what jurors may hear in the state case.
At a May 18 hearing. Carro ruled that a gun and notebook that prosecutors say link Mangione to the killing can be used as evidence. Prosecutors said the gun—a 3D-printed pistol—matches the weapon used to kill Thompson. Prosecutors also said the notebook describes wanting to “wack” a health insurance executive and rebelling against “the deadly. greed fueled health insurance cartel.”.
On Wednesday, Carro dismissed a charge related to a gun magazine that he had ruled inadmissible because it was found during an initial search of Mangione’s backpack at the McDonald’s.
The defense’s path comes with limits that Carro clarified in court. An extreme emotional disturbance defense would not absolve Mangione of responsibility for Thompson’s killing. Carro also underscored that it is not the same as a not guilty by reason of insanity defense. which would allow a defendant to be sent to a psychiatric facility instead of prison.
To establish the defense, Mangione’s lawyers must show that the disturbance was so extreme it robbed him of self-control; that, in his mind, he had a reasonable explanation or excuse for the disturbance; and that he killed Thompson while “under the influence” of that disturbance.
Mangione’s posture and words have already hinted at how sharply the case affects him and his counsel. At a February hearing, Mangione railed against the prospect of two trials, telling Carro, “It’s the same trial twice. One plus one is two. Double jeopardy by any commonsense definition.” On Wednesday. his attorney. Karen Friedman Agnifilo. argued that unsealing the transcript and materials tied to the psychiatric defense would harm him in the federal case.
Friedman Agnifilo said the sealing was requested because the defense is not available federally and because Mangione is being prosecuted federally, making it prejudicial “to the exact same facts.”
Carro had been set to rule on the matter Tuesday, but was forced to delay it a day because prosecutors failed to let Mangione’s jail know that he was needed in court.
In the background of all the procedural movement—sealed hearings. planned evaluations. possible transfers—one question now takes center stage: whether jurors will accept that the killing occurred under an extreme emotional disturbance. If they do. the case’s stakes shift dramatically. lowering maximum prison exposure in the state court outcome from a life sentence to a maximum of 25 years.

So they’re letting him blame emotions??
I don’t get it. Emotional disturbance becomes manslaughter like that? That still sounds like murder to me. Manslaughter max 25 years… yeah right.
Wait, I thought this already was federal. If emotional disturbance isn’t allowed in federal, how can they do it in state like it matters? Also the judge sealed a hearing but they’ll unseal stuff later like that makes it less shady.
This is why people are mad. One judge goes “extreme emotional disturbance” and suddenly it’s not a life sentence. Next thing you know they’ll say he was having a bad day and call it a mental health issue. I’m not saying he should get no consequences, but the system always finds loopholes, especially with rich lawyers.
