A New York judge has delivered a split decision that could shape the prosecution’s case against the man accused of killing UnitedHealthcare CEO Brian Thompson. A gun and a notebook found in Luigi Mangione’s backpack can be used as evidence at trial. Other items seized during the same arrest cannot.
The ruling from Judge Gregory Carro draws a sharp legal line between two searches: one at the McDonald’s restaurant where Mangione was arrested, and another later at the police station. One crossed the constitutional line. The other did not.
The trouble for prosecutors began at the McDonald’s. According to the ruling, officers searched Mangione’s backpack at the restaurant without a warrant. That search uncovered a gun ammunition magazine, a cellphone, a passport, a wallet, and a computer chip. The judge found that the search was improper and ordered all of those items suppressed. They cannot be shown to the jury.
But the backpack was then transported to the police station, where a second search occurred. That inventory search, a standard procedure when booking a suspect into custody, revealed a gun and a notebook. The judge ruled that search lawful. Both items can be presented as evidence.
The evidence ruling means prosecutors keep two powerful pieces: a possible murder weapon and a notebook they claim contains writings pointing to a motive. They lose the rest.
Jurors will likely see the gun. They will likely read the notebook. They will not see Mangione’s phone, his passport, his wallet, the ammunition magazine, or the computer chip, at least not from the McDonald’s search. Prosecutors may attempt to obtain those items through other means, but for now, they are excluded.
The ruling reflects a basic Fourth Amendment principle: warrantless searches are presumptively unreasonable. The judge concluded that no exception applied at the McDonald’s. No imminent danger. No evidence destruction. No consent. Just officers searching a bag without legal justification.
At the station, however, the inventory search followed established protocols. That distinction saved the gun and the notebook.
Mangione’s state murder trial is scheduled to begin September 8th. The evidence ruling gives both sides something to work with and something to fight over. Prosecutors keep their core narrative. Defense attorneys keep an appellate issue alive should Mangione be convicted.
The suppressed items may never see a courtroom. But the gun and the notebook will. And in a murder trial, two pieces of evidence can be enough.
