Theory on Madeline Macann and Yeremi Vargas disappearance?

could these little blonde children be sold by a modern slave trade to sultans or princes of the arab states ,lets face it if you have more money than god you can do what you like and buy what you like too. and no reward money would entice you to give the child back as your already rich. It seems obvious the maccanns were watched and the child snatched when the opertunity presented itself. the abductor must be familiar with the area to get away without anyone seeing . If it was a organised abduction it seems obvious to me that to get a child past borders you need pports or she was hidden ,the best way to get a child into morrocco would be to hid her in a boat if she and other missing blonde children are in the arab states or in a harem they will never be found. god bless the children in this so called civilised society.
