From her mother:

It looks like the people in school who bullied her succeeded beyond their wildest dreams: because of their bullying Nichole fled to internet chat rooms where she met this crazy--instead of being socially involved with other people her own age.
This is very sad. And it really adds a missing piece to the puzzle here. Another reason she was looking for validation and acceptance from strangers.
I hope the other students who bullied her have learned a very important lesson and that this will stop them from ever doing it again.
