Murder Trial"},"content":{"rendered":"<p class=\"css-140ip4z e1me5xab0\">Luigi Mangione\u2019s lawyers plan to argue that he was experiencing \u201cextreme emotional disturbance\u201d when he killed a UnitedHealthcare executive in Midtown Manhattan in 2024, a state judge said on Wednesday.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">The disclosure in the State Supreme Court hearing amounts to a tacit admission by his lawyers that he killed the executive \u2014 the first time his lawyers have done so.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">In New York, if defense lawyers can convince a jury that strong emotions resulted in a \u201cprofound loss of self-control,\u201d leading to a homicide, the highest charge their clients can be convicted of is manslaughter.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">Mr. Mangione has pleaded not guilty.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">Justice Gregory Carro, who is overseeing Mr. Mangione\u2019s case, said at the pretrial hearing that he would unseal documents and a transcript of a hearing earlier this month related to Mr. Mangione\u2019s mental health defense.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">The disclosure comes less than three months before the scheduled start of Mr. Mangione\u2019s trial in September. He faces multiple charges, including second-degree murder. He is also facing federal charges in a separate trial.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">Mr. Mangione, 28, is accused of killing <a class=\"css-yywogo\" href=\"https:\/\/www.nytimes.com\/2024\/12\/06\/nyregion\/unitedhealthcare-brian-thompson-shooting.html\" title=\"\" rel=\"nofollow noopener\" target=\"_blank\">the executive, Brian Thompson<\/a>, on the morning of Dec. 4, 2024. Surveillance footage showed a man in a hoodie emerge from between parked cars, point a handgun affixed with a silencer and fire at Mr. Thompson as he walked toward the hotel\u2019s entrance.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">\u201cHe\u2019s saying that he did it, which is a big concession,\u201d said Gary Galperin, a former state prosecutor in Manhattan who now teaches at Cardozo School of Law. Mr. Mangione\u2019s legal team has the burden of proof to convince the jurors that his action was an understandable response to his grievance against health care insurers, Mr. Galperin said.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">\u201cWhile it\u2019s a viable defense, based on these facts, he will have a high hurdle to convince a jury,\u201d he said.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">While Mr. Thompson\u2019s killing shocked some Americans, others viewed it as a manifestation of long-running frustrations with rising health care costs.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">The state\u2019s case also narrowed on Wednesday, when Justice Carro granted the defense\u2019s move to dismiss a charge related to an ammunition magazine that he ruled last month could not be used as evidence at a trial.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">In his decision last month, <a class=\"css-yywogo\" href=\"https:\/\/www.nytimes.com\/2026\/05\/18\/nyregion\/luigi-mangione-backpack-murder.html\" title=\"\" rel=\"nofollow noopener\" target=\"_blank\">Justice Carro<\/a> said a gun and notebook found inside of Mr. Mangione\u2019s backpack at the time of his arrest could be used as evidence during his murder trial, while other items would be omitted.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">Mr. Mangione still faces other charges in state court, including second-degree murder which could lead to a possible sentence of 25 years to life.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">Last year, Mr. Mangione\u2019s legal team asked Justice Carro for more time to give notice of their intent to offer psychiatric evidence in the case.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">At the time, Mr. Mangione faced the federal charge of using a firearm to commit murder, which made him eligible for the death penalty. In January, a Manhattan federal judge ruled that prosecutors <a class=\"css-yywogo\" href=\"https:\/\/www.nytimes.com\/2026\/01\/30\/nyregion\/death-penalty-luigi-mangione.html\" title=\"\" rel=\"nofollow noopener\" target=\"_blank\">would not be able to seek the death penalty<\/a> against Mr. Mangione, dismissing two counts and leaving intact two stalking charges.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">Extreme emotional distress is a defense that is typically connected to a triggering event that defendants argue created an overwhelming feeling of stress that led them to lose control, said Barry Kamins, a former New York judge who is now a defense lawyer. Some states call similar strategies the \u201cheat-of-passion\u201d defense, he added.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">Where the defense has been successful, Mr. Kamins said, lawyers have argued the crime was an immediate reaction to an event during which the emotional disturbance remains active, \u201crather than over a period of time.\u201d<\/p>\n<p class=\"css-140ip4z e1me5xab0\">Prosecutors in state and federal court have argued that Mr. Mangione\u2019s actions were planned. They have pointed to notebook entries dated months before the killing in which they say Mr. Mangione wrote \u201cthe target is insurance\u201d and described his \u201cintent to \u2018wack\u2019 the C.E.O. of one of the insurance companies at its investor conference.\u201d<\/p>\n<p class=\"css-140ip4z e1me5xab0\">On Wednesday, Joel Seidemann, a prosecutor with the Manhattan district attorney\u2019s office, said the defense team had \u201cstonewalled\u201d them by not disclosing who they planned to call as an expert witness to establish emotional distress.<\/p>\n<p class=\"css-140ip4z e1me5xab0\">Justice Carro ordered Mr. Mangione\u2019s team to hand over that information by Thursday, saying that prosecutors need to know \u201cwhat malady it is that this defendant suffers from.\u201d<\/p>\n<p class=\"css-140ip4z e1me5xab0\">\u201cI\u2019m not going to let you surprise the People on the eve of trial so get it done,\u201d he said.<\/p>\n","protected":false},"excerpt":{"rendered":"Luigi Mangione\u2019s lawyers plan to argue that he was experiencing \u201cextreme emotional disturbance\u201d when he killed a UnitedHealthcare&hellip;\n","protected":false},"author":2,"featured_media":271600,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8],"tags":[92916,15072,30801,46875,9,24,55,54,56,28318,22290],"class_list":["post-271599","post","type-post","status-publish","format-standard","has-post-thumbnail","category-new-york-city","tag-brian-1974-2024","tag-health-insurance-and-managed-care","tag-luigi","tag-mangione","tag-new-york","tag-new-york-city","tag-new-york-city-headlines","tag-new-york-city-news","tag-ny","tag-thompson","tag-unitedhealth-group-inc"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/posts\/271599","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/comments?post=271599"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/posts\/271599\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/media\/271600"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/media?parent=271599"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/categories?post=271599"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/tags?post=271599"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
