Call Child Protective Services. It would be better if you did in the end as no one likes the idea of having sat on the sidelines and watched something happen that they could have changed history and stopped it from happening. How would you feel in years to come if they in fact did turn out the way you feared? Also, just what kind of a normal childhood do you think these kids are having now? As far as I can ascertain, they should not be having a nice, warm, fuzzy childhood. You need to help them now before too much damage is done. Also you need to contact an attorney and discuss your own particular case against your tormentor. You could possibly bring a suit against them or pursue them criminally. An attorney can advise you regarding your rights and the time limits involved in your particular state. Good luck.
