The people suggesting they had to have 'serious personality disorders' to be involved in their daughter's disappearance seem to be those who support them. I have posted a scenario requiring no 'disorders' at all, simply very very difficult decisions.
As far as I am concerned there are NO
difficult decisions for normal loving parents to make on discovering their beloved child is dead. To decide to do anything other than call for an ambulance etc etc is proof in itself that those characteristics which exist in all psychopaths must have been present in the parents imo.
Only abnormal people would hesitate in those circumstances and instead decide to weigh up their options - as if they had come home and found their camera had been stolen - and had to decide whether or not to tell the ins. co they had left the doors unlocked.
This was their beloved daughter FGS, who they had waited years for and who they adored. I can't believe there are people who can't understand the enormity of that - or the immediate massive effect that such a nightmare discovery would have on them - but who do believe that their dead daughter was now nothing more than a potential 'problem' to them - which apparently left them with difficult decisions to make. i.e. Shall we call an ambulance or shall we dump the body? What??
IMO that scenario is not an option to any reasonable minded person anyway - but especially to anyone knowing just how loved and wanted this particular little girl was. It is not humanly possible IMO for people to suddenly change from being normal parents one minute to being raging psychopaths the next.
