A trigger event would make her have an emotional breakdown and with some interference from her father, she would turn. I was thinking somehow she gets convicted for the murder of her classmate (a certain prosecutor could be working the case *wink*) and that'd the final straw for her. This could either be a crossover or I can go solo.

That sounds fine to me and seems like a good story to put her through. Be interesting to watch her spiral and then have to go through a redemption arc.
