was there a lock on ZB door that locked by key from outside to confine her?
was there a garbage disposal on the kitchen sink?
Any Dr. records from the United States (childhood cancer and most cancer REQIRES pet scans etc to confirm still in remission)
The prostetic leg, fitted outside US? Does a child out grow them at some point?
Could the limp in walking be due to neglet on replacement ?
Confirmed cases of 10 year olds that do start menstral (pregnancy due to molestation could result) a strong reason to keep her locked away. Leading to the question could dna from bone marrow be tested for homone that is present in pregnacy.. far fetched but it is possible.
