so the legal summary accepts that an abduction could have taken place
That remark is off topic! The point I was making is that they were neglectful, although not badly enough to be charged.
However;
All options were left open, but abduction seems to have been doubted somewhat, and homicide highly probable (whether after abduction or not);
Considering the participated facts, conjugated with the information that was offered. namely by the witnesses, and with the information that was made available through the development of the inquiry, the investigation equated the verification of several hypotheses: abduction, for the purpose of sexual exploration or others (i.e. posterior adoption, child traffic, organ traffic), without homicide; abduction, followed by homicide with (or without) concealment of a cadaver, hypotheses that were considered under the double sides of the abduction
(if it existed) having occurred due to feelings of vengeance of the abductor(s) towards the parents (directed abduction) or simply taking advantage of the circumstance that the child was in a situation of actual vulnerability (opportunity abduction), accidental death, with posterior concealment of the cadaver and, underlying all of these possibilities, abandonment, substantiated as a crime under article 138 of the Penal Code. The possibility of theft, whose author would have been disturbed by the child Madeleine and who, in order to prevent her from disturbing him, neutralised her in a violent manner, and, afterwards, took her with him, dead or alive, in order to leave no trace that could eventually lead to his identification.
Concerning the other indicated crimes, they are no more than that and despite our perception that, due to its
high degree of probability, the occurrence of a homicide cannot be discarded, such cannot be more than a mere supposition, due to the lack of sustaining elements in the files.
