What's Up With Kenny Cooper?

The first suspect is Kenneth Christensen. People say that he is the most likely of the suspects, but I don't know if you agree with that or not. What's up with Kenneth? Well, no, you got into these letters. You've seen the letters, right? Yeah. How are they signed? They were signed DB Cooper, right? Okay. So what name did he sign on the ticket when he bought the ticket? Dan Cooper.Yeah. He would have signed it Dan Cooper again. It just doesn't make sense that he goes with, but the media have been calling him when he never used that name. Why risk exposing yourself further? Why not leave it a mystery
