K.S.
I work in the legal field. You gave her the right advice go to the Court house and see if any papers were filed. If there were papers reguarding change of custody there would have been a court date. If papers were signed giving over custody they would have to be notorized which the notary is suppose to check id. Hire a private investigator to find her son if she can afford it. This is kidnapping its weird the cops are not doing anything. If papers are not at the Court house she needs to go to Juvenile Court. I dont know what state this is in some cities have seperate courts.
