Sexually assaulted.

I was sexually assaulted when I was fourteen. Fresh in high school, I recently found out the man who sexually assaulted me was arrested for things such as that. I got closure years ago, but now it’s eating at me that I should have said something due to the fact that he got arrested recently for doing the same thing and I could have prevented whoever else he was doing it too also. I feel guilt and I’m not even sure if I contact the police about it now it would make a difference..
