(I haven't read the entirety of this thread, so my apologies if the following has been widely discussed. I have followed the case somewhat, but not super closely, so I know a little but may be missing details.)
I have no added evidence to support the following, so if it is obviously absurd, please let me know what I have missed. It derives from the fact that afaik I know the generalities of this case, and the parental claims of what happened, and have heard the eventual revelation that the family went to eat while leaving Sherin at home.
But when I hear that, rather than try to figure out how that could have happened, and what that means to the timeline of how she might have been hurt and why, I keep coming back to one sticking point in my mind:
I simply can't imagine parents leaving home and leaving a toddler there unattended, to go eat.
That's not a "bad parent" response. It's a "no way that really happened" reaction.
Since it doesn't really add up to me, it makes me think that they left her because they knew there was no reason to keep an eye on her - because she was already been deceased at that point. Were the parents getting out of the house to digest the situation, so to speak, before dealing with it?
Of course, that changes a lot of the framework of who did what, and when, and why, and how, and muddles a lot of the possibilities into things very different.
But, I just don't see the parents leaving her like that. AND - very importantly - it is way too coincidental to me that they just "happened to" have gone out and left her at home, on the very night in which she was later have said to have died by accident. Supposedly odd behavior that supposedly PRECEDED the start of an accidental death situation? I'm thinking there's a very different reality instead, and that's the explanation that to me makes the most sense.
