Update on the abused neighbour (repost)

The last couple of days I've been trying to reach out to teachers and ask about the girl I've been hearing all night screaming. But I realized that my neighbourhood gave me wrong information a few days later because when I checked again, most other neighbours said she attends another school (private one at that), meaning that I can't contact the girl apparently. But I also tried looking into child abuse and threatening laws where I live and that opened my eye to how fucked up the system is. Apparently, even if the dad almost killed his daughter, officers can only make him sign a pledge (?) To not do that again, there's nothing I found about repeating the act after signing the pledge so that made me really upset. I have proof of her screaming and her dad threatening to kill her (the mum also abuses her), its like a recording if a random wall in my room with the voices echoing. But I also found it that I could be sued it for recording without permission which is ridiculous to me but that's beside the point. I can't risk being sued because I genuinely am in a tough spot myself Im barely sustaining myself with all the health issues and set backs I have.

I dont know what I should do anymore I dont want to stand aside and act clueless when I hear the girl (and her little siblings at times) get hit and threatened with strangling. The laws aren't going to protect her and I cant speak to her, hes never out of her house to my knowledge too.

The only lead I could find is a counselor at her school, I actually am still in shock (and a bit in awe?) About that but her counselor was my art teacher when I was only 9 years old. I definitely dont have her contact info and I dont know if she remembers who I even am but I'm hesitant to approach her with this situation. Shes a really sweet person from what I remember but I dont know what my next move should be
