As to the parents disposing of their dead child's body, I can't think of anything that makes that part of his thesis plausible ... it seems incomprehensible to me that these clearly loving parents could carry out such a callous and cold hearted act
Michael Kumars mother cried abduction and left her dead sons body in a wood to be mauled/eaten by wild animals.
The McCanns are not normal people though are they, they are both doctors and used to dealing with death.
Whether or not they could carry it out is another thing.
However, I dont think they would have callously dumped her body somewhere. There was no rush to do so if they needed to.
They were not suspects they cried abduction no screamed abduction and the police were looking at that avenue and whether she had wondered off.
They could have moved her or someone could have for them. Its not far from Portugual to UK about 2 hours flight after all.
who is to say really how someone would deal with it self preservation is very strong in a human beings make up.
