You need to call CPS for where your child is staying. You need to report to them what your daughter has told you. Where I live, you not reporting this could come back on you as failure to protect. Yes also contact your lawyer, but contact CPS now! What is going on with your daughter is sexual assault. You need to get them help ASAP. She can also make the call, but she may not be comfortable doing that. So you need to do it to protect her.
