Taking your first scenario first.
The Pre-planned Snatch Theory
Any pre-planned snatch will have a similar framework cum activity list including but not limited to as we say.
The theory is contingent on certain items being a given i.e.:
1 There was abduction.
2 Abduction was commissioned by a rich type who specifically wanted MBM.
3 MBM was a heavy sleeper witness GM and MO both entering and leaving the apartment without awakening her, according to their statements.
4 According to the timeline drawn up by T9 there were two 10 minute slots after 21:15 when abduction could be effected.
Your imagined scenario that follows of how that could possibly work is quite possibly tongue-in-cheek, but quite well thought out, nonetheless, although there could be variations.
On point 2, however, I don't think I've ever come across a real case in which so-called "elites" have ordered the abduction of a specific child.
I do feel hampered by the fact that it's hard to trace any cases which haven't made international headlines in languages that I don't understand.
Nonetheless, the closest would be the murky Dutroux case, in which various other people in authority may have profited in some way, but still not that a specific child was targeted as opposed to an opportunistic one of a child who may have fitted a general description likely to appeal.
There have been a few other alleged cases, but the only sources I found led back to conspiracy theorists' blogs, with little to back up the assertions.
There is, of course, the abuse in the Jersey and other cases of children in care, but that was different again.
Organised gangs do snatch children for a variety of human trafficking purposes, but I've never heard of one in Western Europe targetting a specific child. That doesn't mean that it couldn't have been a first... ore one that I simply haven't heard of.
I guess that where that scenario falls down for me is that she was specifically targeted, as opposed to any little girl fitting a general descriptionn. On the other hand, if someone had spotted her and knew that that she'd be unattended... who knows?
In any sleepy village or even a large city in which young children are free to play outside would seem to be a far more likely target.
If someone had told me about the Fritzl case before I'd read the news, I'd have thought that they'd been reading too many Stephen King novels... yet it happened. With similar situations coming to light later.
Perhaps I'm wrong, but the idea and the planning involved to target her specifically is a scenario for the back-burner for me at the moment.
