I'm wondering if PF was smart enough to purposely send a red herring with the phone pinging in another state. I have a hard time believing that he's that crafty. I think he possibly just gave evidence to someone else to dispose of, including KB's phone, and said text these messages. I wonder if he even counted on them "pinging" or thought that through. If anything, it seems like he created more of an issue for himself by leading investigators to a new evidence location.
