Why a psychiatric defense may be Luigi Mangione’s best argument



New York — 

The day after Luigi Mangione was arrested in reference to the December 2024 killing of a medical health insurance govt, a former prosecutor instructed his best defense would possibly be claiming a type of madness.

“There might be a not guilty by reason of insanity defense that they’re going to be thinking about, because the evidence is going to be so overwhelming that he did what he did,” legal professional Karen Friedman Agnifilo, then a NCS legal analyst, informed Anderson Cooper.

“You have someone who was a valedictorian of his class, he was brilliant his whole life, he comes from this great family. I mean, something changed, right? Significantly, something changed,” she stated.

Three days later, NCS reported Mangione employed Friedman Agnifilo, a longtime member of the Manhattan District Attorney’s workplace, which is prosecuting the 28-year-old on homicide and weapons fees for allegedly fatally capturing UnitedHealthcare Chief Executive Brian Thompson. Mangione has pleaded not responsible to the state fees, in addition to federal stalking charges.

It is just not clear whether or not Mangione will invoke an affirmative psychological well being defense – the place a defendant admits to the alleged conduct however argues they need to not be held absolutely liable attributable to psychiatric causes – when his state trial begins in September.

But Friedman Agnifilo’s feedback provide a window into what may now be taking part in out behind the scenes:

Last August, in a publicly filed letter, Mangione’s legal professionals requested the choose for extra time earlier than informing the prosecution of their resolution on a psychological well being defense in the event that they deliberate to pursue one. There have been no subsequent public mentions of the problem. A courtroom listening to earlier this month was sealed on the defense’s request.

Mangione is because of seem in state courtroom this week.

Luigi Mangione appears in court during an evidentiary hearing in New York on December 11, 2025.

Lawyers and forensic psychologists informed NCS a psychological well being defense, whereas difficult, is probably going Mangione’s best wager given the energy of the proof in opposition to him. In a key ruling last month, the choose cleared the best way for prosecutors to current the alleged homicide weapon present in his backpack and writings expressing animosity towards the healthcare trade and a want to “wack (sic) the CEO.”

A psychiatric defense might additionally provide a path for Mangione’s legal professionals to attempt to make him sympathetic to the jury.

“There’s absolutely going to be a mental defense in this case,” predicted Kris Mohandie – a forensic psychologist who has labored with legislation enforcement for over three many years – pointing to what he known as a “significant change” in Mangione’s habits earlier than Thompson’s killing.

Mangione’s arrest shocked people who knew him, whereas others appeared for clues which may clarify his alleged motive. Mangione underwent again surgical procedure and posted an X-ray of his postsurgery backbone on-line. In the months before the shooting, Mangione’s as soon as lively on-line presence stopped, and his mom filed a lacking individuals’ report.

“Jurors always want to understand why, and they want it explained, and this will help explain it,” Mohandie, who is just not concerned within the Mangione case, stated of a psychiatric defense. “It will also, in the process, I believe, humanize what is a very predatory attack on this man.”

“They need to do it, and it will render him more sympathetic potentially, if done correctly,” he stated.

Mangione’s legal professionals haven’t responded to NCS’s requests for remark, however they’ve beforehand declined to touch upon defense technique.

Thompson’s killing unleashed a firestorm of ire in opposition to the US healthcare trade and generated a wave of assist for Mangione. Supporters lined up for a probability to see him at courtroom hearings; donors have contributed greater than $1.5 million towards his defense. Law enforcement officers have condemned the assist for him as a surprising “celebration” of a cold-blooded homicide.

A psychological well being defense might be a means for Mangione’s legal professionals to faucet into a juror’s potential frustration with the healthcare trade, Mohandie stated.

“This gets you the ability to talk about a lot of this stuff if you introduce his thought process about it,” Mohandie stated.

On the opposite hand, such a defense may give prosecutors extra info to work with, legal professionals say, permitting them to subpoena medical data and interview a defendant’s relations.

“It opens up the door to different types of evidence that would otherwise not be relevant,” stated Gary Galperin, a former prosecutor who cowrote a research on psychological well being defenses.

“You can speak to employees, roommates, all the persons who might have had contact with the accused,” Galperin stated.

“Psychiatric defenses are often defenses of last resort,” he added. They are not often profitable as a result of a true madness defense requires the accused to haven’t recognized what they had been doing was flawed.

Another affirmative defense accessible to New York prison defendants is that they had been performing underneath the affect of an excessive emotional disturbance spurred by an occasion that made them quickly lose management, authorized consultants stated. If a jury finds a defendant has proved by a preponderance of proof he acted due to an excessive emotional disturbance, or EED, the crime is diminished from homicide to manslaughter, which carries far much less jail time.

“It’s not a get out free (card),” Hermann Walz, an adjunct professor at John Jay College of Criminal Justice, informed NCS. “It’s basically just saying, I’m reducing the crime.”

The EED defense is usually utilized in instances the place a defendant acts within the warmth of the second, corresponding to discovering their partner dishonest on them. It can even be put ahead in instances the place a particular person acts upon feelings which were festering for a very long time, corresponding to abused ladies who kill their attackers after a “long-standing buildup of trauma,” stated prison defense legal professional Earl Ward.

Still, some defendants have efficiently utilized an EED defense in instances that differ from these typical situations, together with when the defendant was underneath the affect of medicine or acted based mostly upon a mistaken perception.

Ward successfully offered the defense when he represented Gigi Jordan, a former pharmaceutical govt accused of killing her 8-year-old son Jude Mirra with a deadly drug concoction in a luxurious Manhattan lodge.

“It wasn’t a question of if she gave her son these drugs – she clearly did,” Ward informed NCS this month. “It really was about her mental state and what caused her to do something so extreme.”

Gigi Jordan, the mother convicted of killing her 8-year-old son, appears in Manhattan Supreme court in New York in August 2011.

During the 2014 trial, Jordan took the stand and portrayed her actions as a mercy killing, telling the jury she believed her ex-husband was going to kill her, which might have left Jude within the custody of a relative she believed had abused him.

The relative denied the allegations, based on NCS affiliate WCBS, and prosecutors stated there was no proof the boy was ever abused.

“Even if her belief was mistaken, as long as she reasonably believed that the child was in danger, she acted under extreme emotional disturbance,” Ward stated.

The jury accepted Jordan’s declare and convicted her of manslaughter, the lesser cost to second-degree homicide. At sentencing, she confronted between 5 and 25 years in prison – a vary far lower than the 15 years to life in jail she would have confronted if she had been convicted of the homicide cost.

In one other high-profile case, Christopher Thomas stood trial for the so-called 1984 “Palm Sunday Massacre,” the place he shot and killed eight youngsters and two ladies in a house in Brooklyn, The New York Times reported on the time.

At trial, Thomas’s attorneys argued he was hooked on cocaine and had grow to be infuriated by his spouse’s alleged infidelity, main him to commit the rampage underneath an excessive emotional disturbance, based on the Times. The jury agreed and convicted Thomas of manslaughter as a substitute of homicide, with some jurors emphasizing the position of his dependancy.

“He had been free-basing for two years,” one juror told the Times after the decision, referring to a methodology of taking cocaine. ”That would make anyone emotionally disturbed.”

Thomas was launched from jail in 2018 after serving roughly 32 years, based on NCS affiliate Spectrum News NY1.

If Mangione finally mounts a psychiatric defense, it might be sophisticated by his own alleged writings and behavior earlier than and after the capturing, which consultants say present perception into his way of thinking.

Authorities allege Mangione wore a hoodie to disguise himself, used a firearm silencer and had an escape plan to flee town previous to his arrest five days later almost 300 miles away in Altoona, Pennsylvania – habits legal professionals stated would undercut any suggestion he didn’t know what he was doing was flawed.

Normally, somebody who acted from EED “would be so distraught after the killing that you would want to talk about it. You would not want to flee. You wouldn’t try to hide your guilt,” Galperin, the previous prosecutor, stated. “What (Mangione) did after the crime seems to negate the psychiatric defense.”

Authorities additionally discovered a pocket book in Mangione’s backpack containing handwritten entries that expressed frustration with the healthcare industry and an intent to hold out an assault, based on courtroom filings. Prosecutors are anticipated to make use of the writings – a few of that are dated months earlier than the killing – to argue it exhibits Mangione’s “unambiguous” intent and motive to focus on the CEO of the nation’s largest medical health insurance firm.

“His journal entries will document that known process we see in people that actually pose a genuine threat, and it will underscore the predatory nature that was cooking all this time,” stated Mohandie, the forensic psychologist.

“Prosecutors will grab a hold of that, but good defense attorneys and mental health people will be mining it to see if there’s any indicator of psychosis, delusion, or just a guy that is so depressed or disturbed that they can use that maybe for a potential defense,” Mohandie added.

“If you ask me whether it’s legitimate or not, I’m going to say I don’t know enough yet,” he stated.
