ToplineLuigi Mangione pleaded guilty Friday to federal stalking charges related to the alleged killing of UnitedHealth CEO Brian Thompson, admitting he “shot” the CEO and avoiding a planned January trial—though it remains to be seen if the guilty plea will get him out of his state trial next month.Luigi Mangione attends a pre-trial appearance at Manhattan Criminal Court on August 11 in New York City.Getty ImagesKey FactsMangione entered the guilty plea at a hearing Friday morning in Manhattan, answering “yes” when asked if he intended to plead guilty to the federal charges against him.The 28-year-old pleaded guilty to two federal charges for stalking related in death, after the court previously threw out harsher murder charges that could have resulted in the death penalty (he initially pleaded not guilty to all of them).He read a statement in court admitting his guilt in the case, saying, “I shot Mr. Thompson in Manhattan” and Mangione “knew what I was doing was illegal.”Mangione did not reach a plea deal with prosecutors and will be sentenced by Judge Margaret Garnett in December, though prosecutors told the court they recommended a sentence of approximately 24 to 30 years, Courthouse News reports.He faces a maximum sentence of life in prison after pleading guilty, Judge Margaret Garnett said Friday, and would have to serve at least 85% of his sentence before being released for good behavior—also noting any sentence he faces in his state case could be added to his federal punishment.Mangione was asked a series of questions by the court about his mental state and whether it was altered in any way as he pleads guilty—answering, “I do,” when asked if he feels “his mind is clear today”—and Garnett said the suspect appeared “fully competent” to enter the plea.Mangione’s lawyers are expected to use any plea in federal court to try and get the suspect out of his separate trial in New York state court, by arguing that “double jeopardy” laws should prohibit him from being tried twice for the same crime, though the state will challenge that argument and it’s unclear if it will work.What Did Luigi Mangione Say About Killing Brian Thompson?In a prepared statement read in court, Mangione said after suffering from years of back pain, he traveled to New York City, posing as an investor to find out information about UnitedHealthcare’s annual investor conference. Mangione used a 3-D printer to create a firearm before traveling to the city. “I traveled to New York with the intent to shoot Brian Thompson,” Mangione said, as quoted by Reuters. “I shot Mr. Thompson in Manhattan and he died.”When Will Luigi Mangione Be Sentenced?He will be sentenced in the federal case Dec. 18, Garnett said Friday.What Happened At The Hearing?Mangione appeared in court and the judge said the suspect was expected to plead guilty. Garnett then asked Mangione a series of questions by the court about his mental state and whether it was altered in any way as he pleads guilty, with him answering, “I do,” when asked if he feels “his mind is clear today.” The judge said the suspect appeared “fully competent” to enter the plea, before asking whether he accepted that he was giving up his rights to a fair trial and faced a potential sentence of life imprisonment. He then read the statement admitting his guilt.What to Watch forMangione’s trial in state court is still set to begin with jury selection Sept. 8, though any plea in federal court is likely to lead to a flurry of requests seeking to fend off that trial. The suspect also faces a sentence of life in prison if convicted of second-degree murder at the state trial, as New York does not have the death penalty.Will Mangione’s State Trial Still Take Place?While the U.S. Supreme Court has broadly allowed people to be prosecuted in both state and federal court for the same crime, New York has a stronger law against “double jeopardy” prosecutions. The state generally forbids prosecuting people twice for the same crime, but there are a few exceptions. Multiple prosecutions are allowed if each prosecution “contains an element which is not an element of the other,” for instance, or if “the acts establishing one offense are in the main clearly distinguishable from those establishing the other.” That means state prosecutors could try to argue that the state charges against Mangione, which include murder and possession of a weapon, are materially different from the stalking charges he pleaded guilty to in federal court. Whether or not that will be successful remains to be seen, with the Times noting prosecutors have previously both failed and succeeded at bringing charges in the past. “It is incredibly complicated,” defense attorney Paul Shechtman told the Times earlier in August about New York’s law.Key BackgroundMangione was arrested in December 2024 following a dayslong manhunt, after Thompson was shot on the streets of midtown Manhattan in the early morning of Dec. 2. The suspect was arrested at a McDonald’s in Altoona, Pennsylvania, and was found with an alleged “manifesto” that railed against corporate greed and the U.S. healthcare industry. Mangione’s case has garnered widespread attention and the suspect has attracted some support amid Americans’ growing disillusionment with rising healthcare costs. The Justice Department initially sought the death penalty against Mangione, bringing charges for murder through use of a firearm and use of a firearm with a silencer to commit a “crime of violence.” Former Attorney General Pam Bondi said she had directed prosecutors to pursue the death penalty “after careful consideration,” citing President Donald Trump’s “agenda to stop violent crime and Make America Safe Again.” The court threw out those charges in January, however, ruling Mangione could only face those charges if the other federal charges he faced are considered “crimes of violence” under federal law, which they are not. His guilty plea Friday took place after Mangione was previously reportedly in talks to reach a deal in June, but negotiations fell through and the deal never came to pass.This story is breaking and will be updated.Further ReadingLuigi Mangione Won’t Face Death Penalty As Judge Throws Out Two Charges (Forbes)Luigi Mangione Trial Starts Next Month—Here’s What To Expect (Forbes)
