I have said that option 4 does not apply to the adductor based in the assumtion that you cant abduct a dead body so I think thats fair. I have excluded option 2 for an abductor based on the assumption that if an alleged abductor had the foresight to consider drugging her to keep her quit, they would equally have the foresite to have her in a car rather than walk through the streets. If the child is being carried by a parent or someone she trusts, it doesnt matter if she is drugged or not as she can be comforted by that person and, therefore will not cry.
Re your option of 2b, either there was have an injury casued by an abductor (unlikely as they want her in good health) or an injury followed by being carried by a trusted person which, again, makes no difference to her behavoir.
Still happy that option three is the most likely (as was confirmed with the first sighting) with option one next most likely. It just doesnt add up that you abduct a child and walk around with her in public when there are clearly lower risk options available. When you consider that the whole point of carrying someone is to get them to a specific point/location, then a car has every advantage in terms of getting them to that point. Following on from that, carrying her only makes sense if your aimed location is within walking distance. You would hardly park the car even 500 meters away and then carry her to the car from the apartment. On this basis, if we go with the abductor theory, what is a reasonable theory as to the location they were taking her to? Clearly, any place locally is extremely risky due to police searches etc so you would want to be as far away as quickly and smoothly as possible. Trying to be open minded but logic moves you away from the abductor walking down the street theory.
