There is no way to definitively “prove” that a conversation did or didn’t take place early in the morning of August 13. The best we can do is look into the dynamics and see what is likely. This may seem like a weak and uncertain investigative technique, but it’s not.
While researching DRILLING FOR DISCOVERY, the 5th book in the ongoing TWO FACE series, I started cross-referencing Watts’ early statements, including to the FBI, with Shan’ann’s references to the word “talk”.
The word “talk” appears more than 350 times in the Discovery Documents, and many are requests from Shan’ann that her husband talk to her. But he doesn’t. This resistance to talking to her gains momentum towards the last days and hours of her life, and in fact one of her last minutes to him on Sunday night is:
Sorry I bothered you. I just wanted to talk to you.
Below are a few of those instances:
Once the murders take place, Watts suddenly tells everyone he “talked” to Shan’ann. He woke her up and he talked to her. Not only did he talk to her, she went to sleep afterwards, and then – apparently – Shan’ann got emotional afterwards and disappeared in a huff.
It’s only when you know the dynamics leading up to the murders, that you can see he wanted to avoid talking to Shan’ann till the last moment, and at the last moment he didn’t talk to her, he murdered her.
