The judge overseeing Luigi Mangione’s state murder case ruled Monday that certain evidence seized from his backpack during a search at the Pennsylvania McDonald’s where he was arrested must be suppressed, while evidence seized at the stationhouse in Altoona, Pennsylvania, will be allowed.
New York Judge Gregory Carro decided a magazine, cellphone, passport, computer chip and wallet should be suppressed, but the alleged murder weapon and a notebook of Mangione’s writings will be allowed.
Mangione’s state trial is scheduled to begin on Sept. 8 for the killing of UnitedHealthcare CEO Brian Thompson, and Carro’s decision will help define the contours of the high-profile criminal trial.
Defense lawyers have argued that the search of the backpack without a warrant violated Mangione’s rights, and have repeatedly urged Carro to block prosecutors from using the evidence.
“At the hearing, Altoona law enforcement officers repeatedly attempted to justify their warrantless search of Mr. Mangione’s backpack … 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’s attorneys wrote in a state court filing.

Lawyers from the Manhattan district attorney’s office pushed back on those claims, arguing the officers acted “in deliberate and painstaking fashion” when they searched the backpack.
“At every step, the Altoona officers responded to this unexpected and alarming situation reasonably,” Assistant District Attorney Joel Seidemann wrote in a court filing, adding that officers later obtained a warrant for the bag “establishing an independent source for recovering the backpack’s contents.”
Mangione pleaded not guilty to state and federal charges after he was arrested for allegedly gunning down Thompson, a husband and father of two, on a Midtown Manhattan street in December 2024.
As Mangione prepares for his upcoming state trial in September, his supporters continue to fund part of his legal defense. Earlier this month, on Mangione’s 28th birthday, his legal defense fund surpassed $1.5 million.
His federal trial is scheduled to begin in January 2027.
