First, I don't trust the DNA identification of the bones so I am leaning strongly toward the theory that the bones were not TH's.
Everyone assumes bones were planted in the pit and barrel but since none of us actually saw that proof, we have to consider the possibility they were never there.
We saw photos of a bunch of rather large bones in a box but Pevytoe testified that the bones from the pit were very tiny fragments, many of which were the size of half a pinkie nail. He further testified that there were 3-4 larger (maybe 1-2 inch) bones in the barrel. There was also burnt insulation in the burn pit that they mistook for bone fragments. For all we know it was nothing but insulation.
So knowing this, how did Eisenberg find 58 pieces of skull bone in the pit? It sounds like there were no big pieces.
She took her bone box to the morgue to do the examination. What's to say someone didn't just take some photos of random bones from the morgue where they do cremations?
Eisenberg worked on another case around the same time as this one -- Shaun Rudy - wife Christine disappeared while 6 months pregnant. Eisenberg claimed she found fetal bones in a burn pit. Months later the body washed ashore - fetus intact. She clearly was wrong about the fetal bones but had they not found the body, I believe the state would have used Eisenberg's testimony to convict Shaun Rudy. He admitted to the murder but the important thing here is that we can not trust this bone evidence and must consider the possibility that the body was not found and that random bones were used to convict SA.
