Yes, wondering the same thing. The theory of a p ring can be published but other ideas can't be published for legal reasons. Think it's self explanatory really. She thinks someone who has known WT, and I mean that in the broadest sense, is responsible for his disappearance.
Bit off topic, but this woman's account of how she feels is reminding me of people I knew whos son was murdered. By the time the perpetrator was sentenced, 3 family members of the victim had committed suicide. I was shocked to find that it is not an uncommon impact of homicide. This is torturous for the victims nearest and dearest. Also, I'm not sure that the police think WT is alive. The impression I got from Jubelin in the interviews I saw was that he didn't think WT was alive but they just didn't have the evidence to prove it either way so he wasn't about to dash the family's hopes. When it was reported by the FM that police think he could still be alive, I remember thinking, that isn't what Jubelin said.
