My opinion of what SS is doing is probably going to be in conflict with most of you but if you translate his posts a bit by removing the swearing and abstractions, the essence of it is very sincere and angry and trying to give Natalie a voice because no one else is speaking up for her. Yes, I agree that certain details about her home life would be better uncovered via case documents, but hopefully it helps some of you who still think he is responsible gain a broader perspective.
I hope those responsible are caught soon and SS can get some help. I know sympathy for SS is a stretch, but put yourself in the mind of someone who doesn't think straight like you do, then add a heap of grief and rage on top.
