It is definitely an interesting and sad story but the interviews with the father, Ron, and his watered down Walmart-level 3rd wife are so unnecessary. Who need to hear from that couple? He's a felon and still acts arrogant although a christian? He's as trash as they come. That 3rd wife has absolutely no reason to talk about this issue at all. She should have been wiped from any footage. The other interviewees contributed more to this series and were much more interesting to watch. All the father contributed was his little man syndrome machismo.
The brother spending his life looking for his sister is just heartbreaking and his parents are the epitome of deplorable human beings.
