Well, it is unusual. The only other explanation I can think of is that perhaps, as her body was small and lean, and if animals had opened up sufficient areas, the fluids evaporated in the dry air, rather than seeping down into the ground. I have no experience with such a case, though, and it still seems to me there would have been at least some drainage from the pelvic area. *CAPPSMADNESS: What do you think?
Anyway, in thinking about to describe how the fluids are produced, etc., it seemed to gross... so I looked up a web site for anyone interested in such:
http://www.dundee.ac.uk/forensicmedicine/llb/timedeath.htm
I think that if the animals would have "opened the corpse up" prior to putrification, then the body could not have been at the site as the defense wants us to believe, wonders, you sound very knowledgeable in this field, without grossing everyone out, think about the natural occurances that occur post-mortem. The bacteria in the body would have started degenerating the tissues within a very short time after death.
I have read about the condition of the body, it was in good enough shape to see bruises, and internal organs (that which remained). I cannot fathom how the defense can expect anyone to believe that the child was placed there shortly after death. If she were "opened up" during the early stages of decomp, then that would expalain the green bottle flies -not to mention that the body would have been in a far more advanced stage of decomp then it was. But if the child was decomposing for 2 weeks (and protected by the mummification)there would be NO GBF's.
