Moments after Luigi Mangione was handcuffed at a Pennsylvania McDonald’s, a police officer searching his backpack found a loaded gun magazine wrapped in a pair of underwear.
The discovery, recounted in court Monday as Mangione fights to keep evidence out of his New York murder case, convinced police in Altoona, Pennsylvania, that he was the man wanted in the killing of UnitedHealthcare CEO Brian Thompson in Manhattan five days earlier.
“It’s him, dude. It’s him, 100%,” an officer was heard saying on body-worn camera video from Mangione’s Dec. 9, 2024 arrest, punctuating the remark with expletives as the officer combing the bag, Christy Wasser, held up the magazine.
Wasser, a 19-year Altoona police veteran, testified on the fourth day of a pretrial hearing as Mangione sought to bar prosecutors from using the magazine and other evidence against him, including a 9 mm handgun and a notebook found during a subsequent bag search.
The testimony shed light on the critical minutes after Mangione was spotted at the McDonald’s and the sometimes unusual steps police officers took in collecting evidence critical to tying him to the crime.
Mangione’s lawyers argue the items should be excluded because police didn’t have a search warrant and lacked the grounds to justify a warrantless search. Prosecutors contend the search was legal and that police eventually obtained a warrant.
Wasser, testifying in full uniform, said Altoona police protocols require promptly searching a suspect’s property at the time of an arrest, in part for dangerous items.
On body-worn camera video played in court, Wasser was heard saying she wanted to check the bag for bombs before removing it from the McDonald’s. Despite that concern, she acknowledged in her testimony Monday that police never cleared the restaurant of customers or employees.
Mangione, 27, has pleaded not guilty to state and federal murder charges. He appeared in good health on Monday, pumping his fist for photographers and chatting with his lawyers as testimony resumed.
The hearing, which was postponed Friday because of Mangione’s apparent illness, applies only to the state case. His lawyers are making a similar push to exclude the evidence from his federal case, where prosecutors are seeking the death penalty.
