If his parents are willing to organise contact with TM then I am suggesting it is not to hard to believe they were involved in other aspects of a purported cover up.
I believe Olivia is also in it up to her eyeballs, my opinion only.
Reasons;
-she was there before police that day, and would therefore have to have asked some questions
-she verified the caterpiller bites (didnt she???, thought I remebered this, but cant find where I read it)
-she verified the bump on the forehead,was from him falling over and hitting his head
-she spoke out about Allisons depression
-she justifies GBCs absence from the search by saying when he wasnt HELPING police with their enquiries he was at home spending all his time with the children (we know he didnt help)
I know these do not make her guilty, it is just giving me a feeling (in my waters)
I know also that family naturally defends family, but I wonder if a couple of these things were not things witnessed but things she has added in order to help GBC. (and maybe she didnt add them intentionally, but the situation seemed urgent and the truth got away a little?)
One thing is for sure, I would hate to be in ANY one of this families shoes right now. Having to answer questions in court will be very tough.
I believe (as others on here have said too) this family wanted Allisons disappearance to be a small paragraph, half way down the centre page of the papers, and then blow over within a week, as some unfortunately do. They hoped their name and standing in the community would help in this regard, as they felt confident the police and public would never suspect spousal involvement in THIS case.
This is why they had such an aggressive attitude towards the "intrusive" media. They wanted/needed to play it down. They NEEDED the media to go away, to drop the story. To let them get life back to normal for "the girls".
All my opinion only, for what its worth. :twocents:
