I am kind of getting at something, but I can't quite figure it out yet. I think there is an answer in all of this.
Zero reports of her taking off that night, but no one saw her so who can say? And there were certainly reports of her taking off the following night, apparently without anyone being too concerned about it. So there is a relevant history for this.
The point is to figure out what happened to her, it is not an exercise to build a memorial or paint her in a good light. That is completely irrelevant to the case. Hiding things in her life that people find unpalatable does not advance the investigation nor does it provide justice to her. Justice will come from the truth, warts and all, pleasant or not, and nothing else.
It will require a bit of digging through old threads, but early on in this case there were reports from family friends who HD apparently lived with for a period, and they described a situation where there was little parental control and she came and went as she pleased.
After HD disappeared, the mother of MB was interviewed and claimed that MB had once overnighted with HD, but that she wouldn't allow it again because she found out later that the girls had been out and about at night.
If that is accurate, that was her life, how she was, and of course it is relevant to the investigation, especially if that in some way played a role in what happened to her. It does not serve any purpose sugar coating that.
The assumption almost everyone has here is that SA did it and that is that. That is a possibility of course, but the timeline makes that difficult to reconcile. I have certainly considered that, and it is still possible, but unless new information comes to light it seems unlikely IMO.
But, I have also considered two other scenarios. One of those is less likely now, since she has been found dead, so I don't think that happened. But the third one is still a real possibility IMO.
So, I want to know where she went, what she did, and who she did it with.
