The Mangione lawyers' sudden decision to drop their psychiatric defence in the high-profile trial of Luigi Mangione has sent shockwaves through the legal community. Just a day after informing Judge Gregory Carro of their intention to argue that Mangione was suffering from an "extreme emotional disturbance" at the time of the killing, Mangione's team withdrew their notice under New York's psychiatric defence statute in a letter to the judge.
The move comes as Mangione's lawyers faced a deadline to provide prosecutors with evidence supporting their claim. Judge Carro had stressed the need for the prosecution to understand "the malady and how that triggered emotional disturbance." The reversal is all the more significant given the seriousness of the charges against Mangione, who has pleaded not guilty to both state and federal counts.
Mangione's trial on state charges is set to begin on 8 September, while his federal trial, which includes stalking charges, will be held from 13 October. By abandoning their psychiatric defence, Mangione's lawyers have opted against potentially admitting to the killing under mitigating circumstances, which could have led to a conviction for manslaughter rather than murder.
The decision follows a previously secret hearing on 3 June, the transcript of which was made public this week after Judge Carro ordered its unsealing. In Wednesday's hearing, Mangione's lawyer had raised concerns that unsealing materials related to the psychiatric defence could prejudice his case in federal court, where such a defence is not permitted.
The killing of 50-year-old UnitedHealthcare CEO Brian Thompson on 4 December 2024 sent shockwaves through the business world. Surveillance footage appears to show a masked assailant shooting him from behind. Words "delay", "deny" and "depose" were found inscribed on the ammunition, echoing language often used by insurance companies when handling claims.
Mangione, an Ivy League graduate from a prominent Maryland family, was apprehended five days later at a McDonald's in Altoona, Pennsylvania, around 230 miles west of Manhattan. A previous ruling confirmed that evidence including a 3D-printed gun and a notebook detailing a desire to "wack" a health insurance executive can be used against Mangione.
