Having gone through a custody fight of my own, I do tend to give the benefit of the doubt to the parents.
Large number of children, a small minority of which being adopted children, and it’s an adopted child that dies under supicious circumstances that includes low body weight. You could open up a red flag store with all of those.
Doubt about a 13 year old losing 30 lbs, and according to the coroner dying outside of hypothermia? The County Prosecutor is evidently weighing charges, and CPS is the agency that removed the other children until their safety can be assured. What else do you have the "benefit of the doubt" about?
