“I do very much remember being dragged down the hallway, put into a room,” Brittney claims of one incident. “He pulled my pants down and he beat me with a bar from a bunk bed.” She claims her bottom was so blistered and bruised she couldn’t sit down for a long time. “I would be afraid when he would come home and I would hide because he beat me so often.”

In the video above, Brittney also describes how she claims Steve would sexually abuse her.
