My special needs daughter has sex tape leak, because of 'friend' and I am going crazy

I am sorry if this is not the place to write this post, I am really going crazy. My daughter is 27 year-old and has Down syndrome, she also has a boyfriend and I try to let them be as independent as possible. There is this boy (36 years old) that has been a friend of hers for a long time and I was happy to see her have so many friends. He is not special needs. <br><br>One day, I saw that there was tiktok video of my daughter and her 'friend' having sex, it was doing well and it made me feel very sick. I talked to her boyfriend and we decided to ask her, she said that she was dating him and that 'friend' did that without her knowledge. That is a lie because she is not stupid, she was not tricked.<br><br>I talked to her boyfriend and both of us decided to call the police, they really didn't do anything. We are heartbroken, because my daughter doesn't have the capacity to make good decisions, but they put the blame on us 'bad parents'. That was a really hard time for us. My daughter still cries a lot and has problems with sleep, she still refuses to see that he did something wrong but I will not back off. I know that he took advantage of her, that's why I'm going crazy, I want to hurt him. He destroyed her.
