I've got to go way back to the beginning
op said this other person is impersonating op yet under their own name. Now, I'm not the smartest guy in the world but wouldn't impersonating someone require them to claim to be the person they are impersonating, ya know, like using their name?
the the current activity where op claims other person is impersonating them stems from this?
Somebody is now sending derogatory/harassing emails to her using a fake email address similar to mine in spelling. I view it highly likely that she is the one doing that, or has one of her cohorts do that.
so, somebody that has an email address SIMILAR to yours is sending emails to this person you claim is impersonating you and you think the person using an email address SIMILAR to yours is in fact the person the emails are being sent to? So, they are harassing themselves? Where are you even involved in this? It isn't your email and you are not the recipient of the emails yet you somewhere see this as impersonating you and is somehow harmful to you.
So, how are you aware of this other persons email contents? Are you hacking their email account and reading their email?
Since the cop said he sees possible civil issues (code for I'm telling you what you want to hear but not actuslly saying anything while doing it) and he is "taking other evidence for the da to review" (another coded message translating to: I'm telling you what you want to hear so I can get the HELL away from this guy), I suspect nothing more will come from the police or state.
