If you're interested in this case, I would definitely recommend this YouTube video over this documentary: https://www.youtube.com/watch?v=D6gz27PhhPs

After watching this documentary i'm convinced the parents did not murder their daughter. All the evidence points to an outside intruder. these torture tactics used on this little girl were used by the likes of john wayne gacy. He was in prison at the time so it wasn't him but maybe its someone who was a copy cat killer who knew gacy or who studied this demented psychopath and murdered this young innocent little girl.
