I have a connection to this family, and I just wanted to say that there are very significant testimony about abuse in this household, coming from the other children in court. There was a hearing that took place a few weeks ago, and everything I've heard (from several unrelated people) that Hana was abused, seriously malnourished and left outside as punishment. That's why she died in the yard, and that's why the other children were taken away. Carri and Larry had seven biological children and adopted two children from Ethiopia a few years back. The children were schooled at home and I was also given the impression that they no longer attended a community church but practiced their religion at home as well. So these kids didn't really get "seen" by society like the rest of normal children do. They existed in a very small and isolated environment, so that may explain why CPS had not previously been involved...
I think CPS might be right this time. As I said, they are not ALWAYS wrong.
There is a cultish family behavior where the parents punish the children by withholding food. If the child sneaks food, the parents either lock them out or lock them in a room.
