But just look at all the mistakes made for someone supposedly just puttin' on an act and playing dumb! You don't think that Chad really thought that nobody ever follows up on missing children, do you? If you think Chad thought that, that is an indication of not being very smart, not being a calculating genius.
As an aside, it was Lori who purchased the rings with Charles Vallow's amazon account prior to Tammy dying, not Chad. That indicates planning on Lori's part, not Chad's.
I don't quite understand the apparent reluctance to acknowledge that when people do these kinds of things, they are not normal, and it is fairly easy to recognize that they are not normal. That is not an "excuse" for behavior, but rather an explanation for behavior, when we are all asking "Why? Why? Why?".
And while we have not heard from Chad's family that he was considered slow, what we have heard (through his brother and sister-in-law) is that a majority of his family at one time or another thought he had visions and was "gifted". They have more or less acknowledged right there that Chad was not considered to be "normal".
Research has shown that severe head trauma can cause epilepsy and that the visions produced during a seizure are often visions of what the person was thinking about prior to the seizure.
So when Chad is out digging graves in the cemetery, what is he thinking about? Dead people who never truly die.
Or the killing of the bees story, where he seems to dissociate and repeats the same action over and over, when suddenly he "comes to" and wonders to himself why he is doing this.
IMO it would take a lot more energy and organization to "fake" this for years, rather than just admit that something is truly "wrong" with him, and I would bet that brain imaging would show this. JMO
