Well nobody knows.
Thats the tip of the iceberg as far as I’m concerned. It appears a good deal of her hair was found in the boot of the car which is the most damning evidence at all.
Apparently, there are going to be further tests on this because they will be able to tell IF the hair was attatched to a ‘living’ or ‘dead’ body at the time.
My brother is a detective and he has told me that you can test for drugs in hair, it stays in your hair longer than it stays in your blood stream. Did they check the other children for sedatives? Also it is reported that the windows and doors were not locked. Is it possible the so called sedative they gave the kids was Benadryl? If they used an antihistamine to get the kids to sleep, it doesn’t alway work. On some kids it has the opposite effect and it makes them wired. It is quite possible that she woke up from a sleep and went looking for the parents herself and was snatched. At 3 years old she knows how to open and close a door. And as someone said, these people are doctors, they know way more about DNA, bodily fluids, decomposition etc. then the average Joe.
