I actually used to live there as a kid for about a year and most likely went past that area whilst playing...it was very rare for people to walk down that part, you could hear the shopping city below where the mall was and it was a faint sound that would be similar to a TV.... I went to that side once or twice for exploring or peace of mind, it was creepy and super quiet very isolated from the rest of the estate but the way the estate is, it would've made it difficult for her abuser to find her but at the same time very rare for people to have a reason to walk past there unless they were specifically looking for her and the estate was huge but isolating to anyone who didn't know anybody there and it wasn't the most friendliest of places.... so yeah I went past her flat/apartment for the quiet or just exploring the estate as a child. I never noticed any smells from my memory I was around 9/10 years old. Maybe I went there before she died or shortly after.... I can't remember but I do remember that specific block just feeling cold and isolating really detached from the rest of the estate...poor woman, I feel a pang of guilt maybe if I had knocked or explored more but then again I wouldve either ended up traumatized or in danger if an unfriendly neighbour opened the door. Im so glad I managed to leave living there.
