Hello John, I think you deserve a big thank you for all the useful information you've posted over this very sad time.
I think a lot hoped you would post at least once or twice during the day for a reliable update. So Thank you from me.
With regard your above post mentioning poor Gaia being in the bush and people still doubting and feeling foul play at was at work I would like to mention that if as you say it was terminal burrowing, (I believe this is the case also), then usually the person can have scraped/scratched or muddied knees, hands, shins, and feet /toes, from getting into their burrow, as in 25% of cases they are naked. I have a feeling some of these marks would have been visible when she was found, and therefore one of the deciding factors on the cause.
