I think it is being bandied about because a disproportionate number of WS members were molested by their own uncles. I know I never had any uncles, but my mother did, and one of them molested her. It is an unfortunate generalization, but based upon "anectdotal evidence" of our membership.
I wasn't molested by my uncle but I am still interested in this person, for the following reasons:
He showed up at the neighbor's door with LE or even before LE, around 8:05 to 8:15 a.m., querying the neighbor. So he had to either live very close to the family, since Dad only discovered her missing at 8 a.m., or be staying with the family.
He seems to want to be in conrol of information or be the first to hear about it, as evidenced by the fact that he has acted as a "spokesperson" for the family a couple of times, even though there are a few reports that state they didn't ask him to do this. Who knows, maybe he's the one who told the family not to talk to media? Just speculating.
And finally, he is new to the family dynamic, having lived somewhere else prior to January. His FB page states that he "loves loves loves" being an uncle and it contains a pic of Isabelle, so he had contact with the family.
Just MOO and this could all be innocent behaviour.
