Danielle was mummified in 24 hours but wasn't completely mummified 4 to 6 weeks later? This guy needs to make up his mind.
This is my take on it.
The skin could have mummified within 24 hrs due to her size and weight. The smaller the body, the quicker the mummification.
I don't know how long the mummiologist said it would have talken the entire body to mummify. If an animal created a new opening, mummification became interrupted at least in that area because of the bugs.
