Not according to an article linked by Brietta a few days ago:
"Speaking to The Portugal News on Wednesday, a Portuguese police source said that while there are “about two or three other cases of missing children in Portugal, but we have a reasonable understanding of who might be responsible for their disappearance. However in the case of Madeleine McCann, we are yet to come up with a satisfactory explanation as to what happened to her”, saying that this a feature of the case that will keep it alive here even if the case into her disappearance were to one day be shelved".
Definitely an interesting link.
About?? ... one would have thought a Portuguese police source would have been more precise and have been able to state exactly how many missing children there are in Portugal.
I think the rather obvious explanation may be that perhaps the cases referred to may involve custody disputes in which there is firm evidence leading to the belief that one parent or the other has made off with the child.
Which perhaps is why they appear to be laid back about these missing children.
As far as Madeleine is concerned, that is not applicable. If the police had a satisfactory explanation ... the case would be solved.
