Do you mean the PM that Sasaki has posted to substantiate his claim as a detective? Isn't Sasaki the one who invented that trick, posting a doctored PM?

As for how he got it to come out accurate, let me ask you this... If it occurred to somebody like myself to exchange PM's in the early days of this game, don't you think it occurred to him?

Redleg on the other hand seems to be pretty direct and open. What's more, while he may develop guile with more games, he'd have to be the greatest natural of all time to pull this off in his first game.
