Because that would explain how frustrated and angry they sound as if speaking to one person. Like they can't prove it and can't just say it. Why is it people think revenge? I read some think he was in some Mafia type stuff but I don't see that because he would have killed them then by now. Maybe some biter enemy from work though. The things done to her either show great hatred against him or her and wanting to teach them a lesson or get revenge and humiliation. So I don't think it's random but don't know if I think revenge but how do we know the jogger who came forward and told the cops why he wasn't running hadn't actually done it? Maybe he wasn't there barely any time and told his wife or gf if he has one that he needed to run some errand and was there and back before she could think anything or even be home from work. My other thought is someone stalking her via her blog
