Yes, and if she was somehow mummified out in an open air environment, by the 16th, at least some insects would have found their way to her during the pre-mummification phase.
Based on what we've just heard, I too, don't see how, as you say, a reasonable person could buy that she was there prior to DW's 24 hour surveillance.
The question, IMO, is who had her and where?
In any case, I don't see it as having been a good day for Dusek and his prosecution team.
It sure is THE question.
