Patrolman Joseph Detweiler was so skeptical when he got the call that he bet his supervisor a hoagie it wouldn't be the real guy.

It was. The man gave officers a fake ID saying he was Mark Rosario from Maplewood, New Jersey. But when Detweiler asked him to pull down his mask, he recognized him almost immediately as the man wanted for the murder of United Healthcare CEO Brian Thompson five days earlier.
