Irrespective of just about everything (screams, SIM cards, walking conditions etc etc), it seems clear that G B-C has been telling lies (walk times, which car he used etc etc). Even a god-fearing married man having a lengthy extramarital affair is a living lie. Bottom line is that if he didn't hurt/kill Allison, he doesn't need to lie about any aspect of Thurs PM / Friday AM. However, if he did kill her, then .....
Just as an aside: Does anyone really believe that Allison watched The Footy Show (presumably NRL) ???????
Based on many years working in mental health, I'm 99.9% sure that Allison did not comit suicide. She had at least 3 very good reasons to live for. From what all have said about her, she was a clever intelligent woman who would have wanted to hang around to raise her girls, and would certainly not want to leave them in the sole custody of G B-C
I agree with a previous poster, most clinically depressed people are not suicidal or irrational, and no one has said anything to suggest that Allison was, or would ever get anywhere near that point.
