Another thing that was suspicious? In one of the emails, Billy spelled his hometown “Pittsburg.” And his friends knew. They said, “We grew up in Pittsburgh. We love Pittsburgh. We are lifelong Steelers fans. And everyone of us, and Billy too, knows that PITTSBURGH IS SPELLED WITH AN H!” So from then on, his friends and the detectives kind of knew that something had happened to Billy and that someone Billy trusted had taken his bank cards and PINS and passwords and was pretending to be Billy in order to keep up the ruse long enough to get more and more money.
