Hi Rob
From what I can gather the DNA evidence under the fingernails itself is inconclusive due to contamination.
I am not completely convinced by the touch DNA either, I agree it raises questions that need answering, but could there have been contamination involved at the lab maybe? If all you need are 4 or 5 skin cells then could it be a lab error rather than evidence. Also why not do touch testing on the paint brush or the garrotte or the blanket and if they did why no DNA there?
Without the results and how they were collected I think there is always goign to be doubt there.
