A judge in New York has determined that some evidence obtained from Luigi Mangione’s backpack during his arrest is inadmissible, while other items can be shown at trial. This includes the alleged murder weapon. Judge Gregory Carro provided his written ruling online in advance of a scheduled hearing.
The ruling agreed with claims that searching Mangione’s backpack at a McDonald’s in Pennsylvania was unconstitutional. The backpack had been moved out of his immediate reach. Yet, a search at the police station was deemed lawful. This search discovered a handgun linked to the murder of UnitedHealthcare CEO Brian Thompson.
Most of Mangione’s statements to Pennsylvania police are admissible, except those concerning an alleged fake ID made after a Miranda warning. Another judge in a separate federal case ruled the search appropriate, allowing the evidence for federal trial use.
An officer found the handgun alleged to be used in the murder of UnitedHealthcare CEO Brian Thompson, 50.
The items include the murder weapon, a 3D-printed silencer, a fake ID, and journals allegedly criticizing the health insurance sector. Mangione is accused of fatally shooting Thompson on December 4, 2024, in Manhattan.
He allegedly fled the scene on a bicycle to Altoona, Pennsylvania. There, local people identified Mangione from a wanted poster and called the police five days later.
Defense counsel noted that the bag was searched several times before obtaining a search warrant. They claimed these searches violated Mangione’s constitutional rights as he had no control over the bag post-arrest.
Prosecutors argued that police acted reasonably, opposing the defense’s motion to suppress evidence.
In New York, Mangione pleaded not guilty to second-degree murder and other charges. If convicted of murder, he faces a life sentence. The defense aims to exclude statements made while he was in custody.
Previously, terrorism charges that could have resulted in life without parole were dismissed. The state trial is set to start on September 8.
In the federal case, U.S. District Judge Margaret Garnett allowed backpack evidence for the federal trial but removed the death penalty as a possible sentence.
Brian Thompson traveled to New York for a meeting with investors. Surveillance footage captured his last moments before the fatal shooting. This incident is described as a politically motivated assassination.
