Accused killer Luigi Mangione scored a significant courtroom victory Monday after a New York judge ruled that key evidence discovered inside his backpack cannot be used at trial, dealing a setback to prosecutors in the high-profile murder case involving UnitedHealthcare CEO Brian Thompson.
New York State Judge Gregory Carro granted a defense motion to suppress several items recovered from Mangione’s backpack following his arrest at a McDonald’s in Altoona, Pennsylvania. According to the ruling, police conducted an improper warrantless search before obtaining legal authorization, violating Mangione’s constitutional protections against unlawful searches and seizures.
“The backpack was not sufficiently in Mangione’s control when Altoona police were detaining him,” Carro ruled.
As a result, prosecutors will be barred from introducing several pieces of evidence found during the initial search, including a cellphone, wallet, passport, computer chip, and ammunition magazine.
“The evidence found during the search of the backpack at the McDonald’s must be suppressed,” the judge stated.
However, the ruling was not a total victory for the defense.
Judge Carro allowed prosecutors to keep other major pieces of evidence obtained during a later inventory search of the backpack, including a handgun and a written manifesto allegedly linked to Mangione’s motives. The judge determined that second search met legal standards after police formally secured the backpack and conducted a documented inventory procedure.
“The People met their burden of establishing that this was a valid inventory search,” Carro said.
The ruling centered heavily on the sequence of events during Mangione’s arrest. Police initially searched the backpack while detaining him inside the McDonald’s before obtaining a warrant. Officers later conducted a second search that uncovered additional items in compartments not examined during the first inspection.
Carro rejected arguments from prosecutors that the initial search was justified by urgent public safety concerns.
“The backpack was within the exclusive control of the police,” the judge said, adding that he “reject[ed] arguments that officers needed to search the bag immediately out of concern for explosives or weapons.”
Mangione’s defense team celebrated the decision and sharply criticized law enforcement conduct during the arrest.
“At the hearing, Altoona law enforcement officers repeatedly attempted to justify their warrantless search of Mr. Mangione’s backpack,” defense attorneys argued. “Instead, all these officers demonstrated was an utter disregard for a defendant’s constitutional rights and a shocking ignorance of basic search and seizure caselaw.”
Mangione stands accused of murdering UnitedHealthcare CEO Brian Thompson in what prosecutors describe as a politically motivated assassination carried out on a Manhattan street. Authorities allege Mangione targeted Thompson because of ideological hostility toward the American health insurance industry.
Federal prosecutors have portrayed the killing as a calculated act intended to spread a political message through violence.
“Brian Thompson was gunned down in cold blood as he walked down a street in midtown Manhattan,” Acting U.S. Attorney Edward Y. Kim previously said. “This wasn’t a debate, it was murder.”
According to prosecutors, Mangione traveled to New York, stalked Thompson, and carried out the shooting in broad daylight outside a Manhattan hotel.
The case has attracted disturbing support online from some activists and political commentators who framed the killing as justified retaliation against the health insurance industry. Left-wing streamer Hasan Piker sparked backlash after referring to Thompson’s death as “social murder,” using rhetoric critics argued effectively rationalized political violence.
Meanwhile, Mangione has developed a growing online fan base among extremists who portray him less as an accused murderer and more as a symbol of anti-corporate rage.
