Naomi of course I am not ignoring you. I presumed the question was hypothetical, considering I was not there. Any scenario would be pure conjecture,but at the same time, as credible as any scenario proposed by someone who believes Madeline was kidnapped, as there is no evidence to suggest she was either.
However, there is evidence to suggest a cadaver was present in the holiday apartment, and pathological evidence of blood in the rear of the McG's hire car. Many people argue over the validity of this evidence, and even if this evidence actually existed, but there is not one shred of evidence to suggest the child was kidnapped. No evidence of foriegn ( as in not part of the family) DNA at the scene, no evidence of forced entry or exit. I subscribe to the theory it was an accident, a cover up, and the poor child was already dead when the Police were called. I hope I'm wrong and Madelaine is found somewhere living a life as a gypsy or whatever but I doubt that.
