Danikay......
You said that she hasn't been going to Jr. High with her, but will be attending HS with her. Have the two of them had any interaction since changing schools? I know you said that you live in different parts of town too.
I'm thinking that since she's been away from her, the girl may have found someone else to prey on in her absence. A lot changes in those years, so maybe things will be better.
All i can suggest is for your daughter to steer clear as much as possible, and do her own thing, and not re-ingnite any past issues. I'm sure that if this girl is as bad as you say, she'll get hers in the end. Most likely one of us will be locking her up in the near future.
In god we trust, all others we run NCIC.
