You have no way of knowing that these accusations were not born out of some sort of fact.
Are they guilty of murder. The simple fact is, none of us know.
Are they guilty of neglect. Most certainly.
Had they been a working class couple social services would at this stage be re-homing thier other 2 kids.
Could it not all be possible aswell that the pulicity that they were part of and the whole campain to find maddy might not of been so they could say 'we wouldn't have done that if we were guilty now would we'
On the other hand mabee they are in denial, and the longer they kept telling everybody she was taken and is still out there somewhere the more they themseves might bellive it?
With the way the portugese police are handling this investigation we may never know the truth to any of the questions still un answered.
