In the cong I grew up in a 'sister' married a guy with 3 teenage children. Her own kids were all grown up married and moved away.
This lady gave the oldest girl the worst time. The poor little thing was about 15 at the time. For the slightest even imagined infraction of this horrible ladies high standards resulted in a beating so severe that the poor little thing sported black eyes and other assorted scratches, cuts and bruises. She had no qualms in sporting this kind of behaviour in front of anyone. I personally saw her punch, slap and scratch the little girl.
At the time I was about 19 or 20. I tried my best to befriend her. I ended up studying the young people ask book with her. (It was all I knew and I thought it was the best thing I could do) until after the bookstudy one night. We were having a cup-of-tea night (light supper at conclusion) and the little girl had been banned from eating anything. The wicked stepmother literally sat in front of her scoffing her face with cakes and biscuits etc. The poor little girl retaliated snatched a chocolate cookie and stuffed it into her mouth. Well the reaction that this got from her stepmother was the WORST display of child abuse in public. One of the 'brothers' pulled her off the child (mind you her own father stood by and let it all happen) and the little girl ran out of the house.
I left and called child services and informed them of what had been going on and the recent events. The little girl was picked up and they must have seen the bruises or something because they took her away.
I never heard from her again until a few years ago when she was at a shopping centre I was at. She walked up and just smiled and kept walking by. I don't know if she ever realised that I was trying to help her and she didn't want to bring up the past or what happened. It was the most disgusting display of chid abuse right there in the loving WTBTS organisation.
