Kenny said police did not identify Mangione by name before he was arrested.

“There’s a lot of relief in this case because we’ve recovered an incredible amount of forensic evidence, an incredible amount of video. So I wouldn’t be able to put it in one thing. But if we had to, it would be to release that photo,” Kenny said. “We took that photo and asked the citizens for help in identifying this subject, and the citizens responded.”
Kenny said detectives spent hundreds of hours combing through “every video source we could gather.” Using the video, detectives were able to follow the killer from the scene of the shooting on foot and by bicycle through Midtown Manhattan, Central Park, and uptown Manhattan. Detectives also obtained video of him shortly after he arrived in the city by bus.

“The footage we shared with the public was widely circulated, and the tips we received led to the recovery of crucial evidence,” Tisch said, acknowledging the “instrumental role of the media and the public in this case.”
Tisch added, “We should never underestimate the power of the public to be our eyes and our ears in these investigations.”
He said it was the third time in as many weeks that a tip from the public led to an arrest in a high-profile case, including a triple stabbing homicide in Manhattan and several armed robberies in Queens, while he was a police officer. shot
Kenny said the investigation is far from over, as detectives continue to look into whether the gunman had any help.
“We believe, at this point, our investigation is only pointing towards who played,” Kenny said.
Looking forward, Tisch said, “we will work through extradition to return him to New York to face the charges here, working with the Manhattan District Attorney’s Office.”
