You need your own attorney in this matter to cut through their nonsense and put some pressure on. Not clear what age your daughter is, but medical evidence can be established, counseling can be sought, and you can go on the offensive.
We do not have a client/attorney relationship until you make an appointment, we discuss your case face to face, I accept a retainer, and we explictly agree to enter into representation.
You do not state whether there is a court case going, whether you and the mother were ever married (or if the child was ever legitimated through legal process), nor how old the child is.
I have to presume there is some sort of case going on, because of the Guardian ad Litem. Presuming you are the "legal" father you may want to look for a change of custody in the Superior Court... If you are not, you may look to a deprivation proceeding in Juvenile Court (which can change custody temporarily).
In either case, you need experienced legal counsel. I cannot recommend strongly enough that you hire an attorney to assist you with this.
I wish you the best of luck. If you ahve any other questions or concerns, please feel free to contact me directly at firstname.lastname@example.org
What should you do? Hire an attorney. Immediately.

You do not indicate in your question that you have an attorney. I would recommend that you retain an aggressive, qualified and competent attorney to protect your rights and the rights and safety of your daughter. Additionally, I would make sure that I have all of the photographs, medical reports and any statements your daughter has made to law enforcement, hospital personnel or DFCS. I advise you to be aggressive in the defense of your daughter and put pressure on the system to act in her best interest. I hope this information has been helpful to you. Good Luck!
