I am so puzzled. I know appearances can be deceiving but there really is no indication either grandparent would harm child. I also dont think that if either grandparent had child because they had to get away quickly after seeing or being involved in something bad, they wouldn't contact Nathan's parents. I have a gut feeling that there has been contact with Nathan's parents because of the silence since their first statement. Which leads them to be in the position of not being able to speak for fear of jeopardizing the investigation. Its a long stretch to go from cooking meth and impersonation to killing a child. I just dont see it. Also if DG had indeed been involved in a car crash that killed someone, the media would be all over it and it would have come out at his court case. More likely is that he knew the family or that he didnt know the family but read about it in the paper. Yet why would he take that identity? I think the accident got to him for some reason. Does anyone know anything about MH and his sister's parents? Have the police talked to them?
