So hey I am 14. My parents are on a business trip so I am staying home alone. I was talking to this girl named Jane on the phone. I don't like Jane at all, and I was only talking to her because we were making arrangments for this party. Then I heard someone like yank her and scream out you fucknbitch. Then some man came on the line, screamed BYE and hung up. I was worried and eventhough I dont like her I grabbed my purse and ran to her house. I peeked through the living room window and saw Jane's dad HITTING HER! Jane got up and screamed at him and slapped him and he threw her against a wall and hit her. OK THIS PART IS SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO GROSS ... She was wearing this white tank top and jeans. He was wearing boxers and a tshirt. He grabbed her, and he was like tiittt fuckinng her with her clothes on! Like they were both wearing clothes, but he was rubbing his dickkkkk on her booooooobs and grabbing her by the hair! I took pictures and ran. I saw her at McDonalds with her friends this morning and she looked really happy! I went into the bathroom and sent her a text mesasge telling her to come to the bathroom Then I told her I saw everything and she begged me not to tell the police, and she said her dad only beats her when he is drunk. And usually she fights back but last time she was loosing to him so she didnt. Then I flat out asked her if he ever raped her. She didn't say anything. She left. I am really worried! I think I will anonomisly tell the police. What should I do?
