Actually re the burn barrel, I thought the defense team’s explanation not only exonerates Avery but points to / proves that she was burned elsewhere and transported in burnt remains to his site.
There is no reason for him to have murdered her and burnt the body and then put bits in a barrel and elsewhere. But logic dictates that the framers needed to transport the remains in a barrel or something.
This may be where they could get some new scientific evidence to open a new trial: can burn fragments tell what they were burned with? If evidence of non-body remains are still saved, perhaps it can be proven that her bones were not burned with rubber / plastic / metal car parts that were thrown in. The way you can tell (without microscopic evidence) when a meat was cooked over a certain type of wood.
Also hire an independent to do the blood analysis. There is no doubt in my mind that Lt.Lemm used that old evidence blood to put him in the car. The preservative chemical had to be in that sample. The FBI went through the motions and offered up what they needed to hear. Also the jury was in the dark about this and some other issues. Interesting stuff. Food for thought. It just shows what a person is up against when accused by the state of a crime.
