Report it to the fucking cops!!!!! If some one told you that an adult is having any sort of inappropriate relationship with a minor why wouldn't you tell the proper authorities not your supervisors. Those kids lived will never be the same, after years of therapy they might be able to function normally but that is a huge if. I think any one that knew and didn't press the issue should be charged as an accomplice. Maybe I am over reacting but shit like this should never happen yet it keeps coming up in news stories.
