On another post on FR, I read they found NO porn on his computer. Who ya gonna believe? I would investigate further on this one and not just assume Westerfield is the killer. I don't trust the parents either. Poor kids, they're the ones who always suffer when parents behave badly.
I think the chances are greater that an outsider did it. The porn issue, regardless if it was on his harddrive or zip drives...is a factor for the prosecution at this time..that to me is the bottom line.
Yes, the kids are in a TERRIBLE situation. I can't imagine what they must be going through. To have complete strangers saying their parents possibly had a role in their sisters death..i hope they don't hear about that, or are protected from it until they become much older.
