No, I have no idea of her diagnosis. It's only my opinion from knowing one very well and reading the details of this case and seeing where she is being kept is a specialist unit.Do we know that her diagnosis is BPD? Or is that an assumption?
I think I just get really frustrated by many cases (Jamie Bulger, kayleigh haywood) this one included, where people witness things but, do nothing!
The friend/neighbour witnessed Sabrina beating Sophie (is it the same neighbour who took Sophie into her home at some point?) But didn't report it to anyone.
There were many chances for intervention here, it's unbelievable. I suppose a lot of the final stages took place during the school summer holidays so the children weren't being observed by teachers if they had said anything, but that's only one aspect, we know friends did nothing, and others. Neighbours would report a bonfire, but not all the shouting and screaming that went on!
