Thank you for the maps and pinpointing where she was located. I also feel she is from a local household, and posted a map in the last thread about MOO of where the girl probably came from. The location she was found appears to be a park-ish lookout point, so I think there is sentiment attached to this location.
I don't think a case like this is common so there aren't a lot of situations to compare it too, but I think knowing what might be behind the psychological thought process of someone who bags a dead child with her blankie would be useful. Deep in my heart, I feel like this was a "burial at sea" and whomever placed her there expected her to be washed out and to sink. They say she wasn't in the water very long (at most a few days?), so were there flowers or any other out of place items nearby, or out in the water? Further, until COD is determined, my gut instinct says it was some sort of accidental death that the person feels they will be in trouble for, and someone is grieving deeply right now, alone and in silence.
Earlier someone mentioned a prostitute, and I very much feel this child is a daughter of one such young woman.
I've read through all the posts and many of you have touched on questions I have as well. I have questions about her clothes. They were quick to provide images of her clothing, and there is no shirt. That is concerning, unless she often went without one. I know some little girls still quite young do. Did she have panties? If not, coupled with the missing shirt, I question other motives. I hope they checked for signs of sexual abuse, although some how I don't think that is actually a factor in this case.
