<human>: Can you provide a brief overview of the text?

Hello!

I used to be a casual lurker of this site, but recent information about my niece's best friend's plight urged me to make an account and come to you for help.

My niece and her best friend, both 14, were going to sneak out of their houses to meet up at an abandoned school in their neighborhood about two weeks ago. My niece happened to fall asleep, and she woke up to texts from her friend saying, "I invited this guy, he's 20." "Hello?" "you comin?" "HELLO?"

...

"We're never going back to that school again."

Naturally, my niece got scared. Two days later, her friend was able to come out and say what happened. She had been raped.

This girl is too afraid to go to the authorities. Due to some other personal troubles, child services has come into her life, and she doesn't want to risk breaking up her family. I was able to talk with her myself today, but as I'm not a licensed counselor or lawyer or anything, I was only able to give her many hotline numbers where she can call in and the advice to open up to her parents. It's unfortunately too late for a rape kit, but it's still soon enough to put in a police report before her rapist harms anyone else.

Side-note: On my part, I am so thankful that my niece didn't go with her friend. As heart-breaking as this whole thing has been to find out, I'm grateful that it wasn't made worse. My mind raced with all the possibilities, and my 
own beautiful young lady is suffering through a survivor's guilt.

I'm in a different state, so I cannot call and report it for her, much as I'd like to. She did, however, give me her rapist's personal information: his name, his facebook profile, where he works and goes to school.
<bot>: my question for you, Reddit, is what can I do with this information? What would you do with this? How would you handle this? Can anyone help me? Can someone help a scared teenager?
