Defend An Ignored, Abused Child

My abused daughter has been ignored by police, the state attorney and the courts, despite the police having very graphic photographic proof that physical abuse has occurred. Furthermore, my daughter has verbally accused her mother of throwing her down a flight of stairs, resulting in physical injury between her legs. The hospital who examined my daughter, contacted DCFS, who refused to investigate.
I have social worker reports, hospital evaluations, videos and photographs that state my daughter has been abused physically and possibly sexually.
Please, stop ignoring my daughter and grant her justice.
