A New York judge handed prosecutors a split decision in the Luigi Mangione murder case, ruling that the suspected gun used to kill UnitedHealthcare CEO Brian Thompson can be shown to jurors at the September state trial, but that other items seized from Mangione's backpack during his arrest at a Pennsylvania McDonald's must be thrown out because the initial search violated the Constitution.
Judge Gregory Carro posted his written ruling online ahead of a Monday morning hearing in Manhattan. The decision followed several days of testimony from 17 witnesses and months of legal wrangling over whether Altoona police crossed a constitutional line when they searched the 28-year-old suspect's belongings without a warrant.
The ruling matters because it determines what a Manhattan jury will see when the state trial begins September 8. Mangione faces a top charge of second-degree murder, which carries a maximum sentence of life in prison. He has pleaded not guilty to all state and federal charges.
Carro agreed with the defense that the warrantless search of Mangione's backpack at the McDonald's was unconstitutional. The bag had already been moved away from Mangione's reach. He had been frisked, handcuffed, and read his Miranda rights. Under those circumstances, the judge found no legal justification for officers to dig through the backpack on the spot.
Officers at the scene had said they were concerned the bag might contain a bomb. Carro was unpersuaded. As the Washington Examiner reported, the judge wrote that "while the body-worn camera footage showed that officers did express concern at the scene that the backpack might contain a bomb, there was no evidence that a gun was a concern or that it was the basis for the search."
"But even if it were a legitimate concern, there was no possibility at the time of the search that the defendant might retrieve a gun from the backpack, and thus no exigency," Carro wrote.
The suppressed items include a loaded handgun magazine, a cellphone, a passport, a wallet, and a computer chip, all taken from the bag at the restaurant. Defense lawyers had argued in a letter to the court that authorities searched the bag "multiple" times in the eight hours before obtaining a search warrant.
The bigger prize for prosecutors stayed in. Carro found that a subsequent search of the backpack at the Altoona police station was lawful. That later search turned up the suspected murder weapon, a handgun, and a handwritten notebook that prosecutors have described as containing damning writing. Fox News reported that an officer found the handgun during the station-house search, and the judge concluded the search complied with department protocol.
Just The News noted that the judge rejected the defense argument that the gun and notebook, which prosecutors have called a "manifesto", were illegally seized. Carro drew a clear line: the McDonald's search was improper, but the station-house search stood on its own.
For prosecutors building a murder case, the gun and the notebook are the evidence that matters most. The magazine, phone, and passport may add texture, but a jury looking at the alleged weapon and the suspect's own written words will have plenty to consider.
Mangione's defense team also tried to suppress statements he made to Pennsylvania police between his December 9 arrest and his extradition to New York ten days later. Carro allowed most of those statements in, ruling them admissible. The exception: some remarks Mangione made about his alleged fake ID after police read him his Miranda warning. Those will be kept from the jury.
The ruling on statements is significant because it means prosecutors can use much of what Mangione told officers in the days after his capture. Courts routinely scrutinize whether judges evaluate police conduct and evidence handling in criminal cases, and Carro's decision suggests he found the Pennsylvania officers largely followed the rules, even if they stumbled at the McDonald's.
Mangione faces parallel proceedings. In his separate federal case, U.S. District Judge Margaret Garnett already rejected the same defense argument about the backpack search. In a January 30 order, Garnett ruled the evidence could stand in the federal trial. She also took the death penalty off the table.
So the federal jury will see everything. The state jury will see the gun and the notebook but not the magazine, phone, passport, wallet, or computer chip. Two judges looked at the same arrest and reached different conclusions about the initial search, a split that underscores how much Fourth Amendment law depends on the judge in the room.
Mangione also faces six weapons-related charges and one count for allegedly possessing a fake ID. The judge previously dismissed terrorism-related charges that could have put Mangione in prison for life without parole if convicted. Prosecutors had described Thompson's shooting as a "politically motivated assassination." Without the terrorism enhancement, the ceiling is life with the possibility of parole.
The case traces back to December 4, 2024, when Mangione allegedly shot Brian Thompson from behind outside a Manhattan Hilton hotel. Thompson, 50, was a father of two from Minnesota who had come to New York City to meet with Wall Street investors and was walking to a business conference when the attack occurred.
Mangione allegedly fled the scene on a bicycle and made his way to Altoona, Pennsylvania. Five days later, customers and employees at a McDonald's recognized him from a wanted poster and called 911. Police arrested him on December 9. He appeared the next day at Blair County Courthouse in Hollidaysburg, Pennsylvania, for an extradition hearing.
The case has drawn intense public attention, with some corners of the internet treating Mangione as a folk hero for targeting a health-insurance executive. That reaction says more about the state of public discourse than it does about the law. A man was shot from behind on a sidewalk. The criminal justice system exists to hold the accused accountable, not to weigh whether the victim's employer was popular.
High-profile violent-crime prosecutions often turn on exactly these kinds of pretrial evidence fights. What a jury sees shapes what a jury decides. Mangione's defense won a partial victory by getting the McDonald's search items tossed, but the items that matter most, the gun and the writings, survived.
The state trial is set for September 8. Between now and then, both sides will continue to maneuver. The defense scored points on the Fourth Amendment question, and Breitbart reported that Carro's reasoning rested on the straightforward principle that a handcuffed suspect cannot access a bag that has been moved away from him, making the warrantless search unjustifiable.
But partial wins don't acquit defendants. The prosecution still has the alleged weapon, the notebook, and most of Mangione's own statements to police. Those are the building blocks of a murder case.
Open questions remain. What exactly did Mangione write in the notebook that prosecutors consider so damaging? What were the specific statements about the fake ID that the judge suppressed? And how will the defense handle a trial where the gun is on the evidence table but the phone and passport are not? Investigators in other complex criminal cases have seen prosecutions hinge on exactly how evidence was uncovered and whether courts let juries see it.
The constitutional questions raised here are legitimate. Police should not be able to rummage through a suspect's belongings after he's been cuffed and the bag is out of reach. Carro was right to draw that line. But the Fourth Amendment is a shield for everyone, not a get-out-of-jail card. And when a separate, lawful search at the station house produced the same firearm, the defense argument lost most of its practical force.
Questions about prosecutorial conduct and constitutional boundaries run through the justice system every day. What matters is whether the rules are applied consistently, to the powerful and the powerless alike.
Brian Thompson's family deserves a fair trial. So does Luigi Mangione. What neither side deserves is a system that lets procedural technicalities erase the facts of what happened on a Manhattan sidewalk in December 2024. The gun is in. The notebook is in. Now let a jury do its job.
