:goodpost: GREAT post, Jane!! I get exactly what you're saying and I personally believe this to be the issue in many more cases than just this.. I've got the perfect example of a case that we just followed(yes, you too).. The Samantha Koenig case.. Think about how many ppl misread that situation with her dad, James and IMO its not their fault for feeling this way, as in they felt a great sense that James knew "something" therefor could've possibly played a part in his daughters disappearance.. Now in hindsight we see exactly why it was that ppl were sensing that James knew way more about what was going on than what he was leading the public to believe.. Of course he did.. My God this poor dad had been contacted by the abductor and what we all later learned the murderer of his beautiful, young daughter, Sam.. He did know more.. But yet at the same time that did not make him in any way whatsoever involved in the abduction or harm that came to his daughter..
So, yes, I totally get what it is you're saying as well as I absolutely believe that could be the case here with precious Isa.. For the exact reasons and/or scenario that you gave in their feeling or knowing in their hearts exactly who it is that possibly has done this to Isa and their feeling tremendous guilt for having possibly brought the person in to Isa's life or better yet they're going through all of those God forbidden "what ifs" of having not noticed more, been more aware, or possibly have done something as a preemptive measure to have kept this from happening to their precious Isa..
ITA and believe its an excellent point that people should consider in not just this case, but others as well..
The whole demand statement dad made is really sticking out to me right now in context of your post. I know LE said no ransom was involved in this case, but now I'm wondering if mom and dad know something different that they may not be sharing with LE to full extent? It's not something I remember hearing in any other cases, so it's stuck in my mind. I'm probably way off base on this, it's a random thought I had.
