Ok, so it looks like he goes to court in Feb. and hopefully the investigators will be able to sort out if this is him doing this or someone using his identity. I would most likely feel very different about this, if I hadn't seen what I have online.
Although it's not uncalled for that a deranged individual would use their real identity to do this, usually they will try and mask that by using someone else's.
There are many ways a person can hide behind proxies to do this.
I have seen to many peoples names and photos stolen and used for this purpose. I want to see what the investigators find.
I am a strong advocate for victims. I would have to agree with the detectives about posting his name. If it is not him and someone else there could be repercussions for defamation. Let the investigators do their work first. If she is convinced it's him and it turns out not to be, then she may be opening herself up to a vulnerable situation, i.e. trusting the wrong person.
Although I agree with the concept of warning others or reaching out to others that may have been victims of this person, by doing so without proof of who it is, may provoke her stalker.
This situation is a little different than say a situation where you know who your attacker is for instance.
