My daughter is 15 months old. I have had physical custody of her since June of 2014 in the state of Washington. Her mother lives in Indiana. I have been told by my daughters Aunt and Mother on the mothers side that her mother is with an abusive man who is using drugs and abusive to her mother. We have no legal custody issued by a court. Her mother is a convicted Felon and has 4 children by 4 different men. She has lost custody of her oldest. That child is with the mothers father. I'm concerned for my daughters safety around the mother and her boyfriend. I'm married have a stable career and my wife is a high scholl special education teacher with a Masters degree. My daughter barely knows her own mother and I don't even have any way to contact her because she has no phone and I don't know where she lives. With that said everything I've read say she can come take my daughter away and I can stop her. How should I proceed?
