NYC prosecutors share evidence photos revealing Luigi Mangione's possessions at time of arrest

The exhibits shared Saturday night included a picture of the USB on a chain that Mangione was wearing around his neck when he was arrested, a bus ticket to Pittsburgh, a handwritten note with a Best Buy list and "to-do" list, and a pocketknife with zip ties.

Additional photos show the clothing Mangione carried or wore, including green and black jackets, a beanie, scarf, black pants, black gloves, long underwear, sneakers and a medical face mask.

Prosecutors argue that police acted lawfully and appropriately, that the warrantless search of his bag after his arrest was routine and legal and that the only relevant non-Mirandized statement he made was to allegedly give officers a fake name when he showed them a phony ID.

At the end of the five-minute call, the dispatcher told the manager to sit tight and remain vigilant.

"I do have an officer on the way for ya," the dispatcher said. "Just keep an eye on him. If he leaves, just give us a call back and let us know, OK?"
