Before some years I have seen on german television a documentation about female twins in usa (not sure). The parents had spoken german and english and they thought the girls are mentally handicapped so they treat them like this. The girls create their own language. When the girls were found, many experiments were made with them to check up if they were mentally handicapped ore not. I remember later one of the girls died ore was put into another family. The other girl was send into a sanatorium.
I searched in the net for this case but I could not find anything. I hope somebody know this case and could give me some information about.
