Also, unless they didn't release this information at first, nowhere does it mention the phone calls JK received while being there. It also seems like she started getting nervous around the beginning of July, as that's when she starts getting defensive. I think it's interesting the FBI agent said to look for someone whos being defensive, and he believed someone directly or indirectly knew who was involved.
Can you post the article where she comes across as defensive? I would love to see it.
