I cant understand these "trolls' on the internet, it is such a huge thing isnt it. Every facebook page about missing/deceased/victims of crime I have seen since being on facebook has ended up with postings by trolls, and they dont stop no matter how often people plead with them or tell them what for. I think the best thing to do is to ignore them, something has to be done as it seems to be getting worse.
Now back to this case, i have just looked at the photo of the house. Is that a little neighbourhood or do they live on some sort of property? as in own a couple of acres. The reason I ask is that we know the neighbour heards the scream. if they are on a property she must have been screaming really loudly, which makes me wonder again about why the brother took an hour to ring 911.
