I just looked over at the maps of the area and IMO the home is precariously close to that river. First, I can certainly imagine an inquisitive 3 year old wandering around and find it. It is really just across from the backyard neighbors house and it doesn't seem a well trafficked area. The Google road doesn't even extend there. Second, it would also be a very easy place to dispose of a body quickly, in the wee hours of the morning.
How much do we really know about Ralph's movements that morning. Supposedly he left the house early that morning to go to work and he did in fact work that day. I would imagine that would give him a solid alibi for that time. Or did LL go back to bed while he was still home? Is it possible that he did something after they all woke up and the kids went to bed with mom. Why did they do that, leaving AL alone in the room? Did dad ask them to do that? Was dad home while LL and the kids were in bed and could have done something before leaving for work?
Also, I am quite concerned about the dogs following Aliayah's scent to the river and then disappearing. Does anyone know if they used cadaver dogs to trace that scent or would there be a way of knowing if the dogs were tracking the scent of an alive child, rather than a body?
