I'm sure officials in Tennesee will investigate.
Sadly this happens more often than people think, even here in the US. The adopted kids from Russia, Romania and the Ukraine have a history of attachment disorder. That is common knowledge and anyone who wants to adopt should be doing their own advance work to fully understand what they are getting into. Here in the US, when adopting an older child from the foster care system you can ask to review their entire file. You should know the details of the childs past; why are they no longer with their parents, are there other members of the bio family who may want to continue a relationship, how many foster homes/schools have they been in, what has the counselor stated from visits, etc. To fully love and parent these children you must know what they have survived so far in life.
