I know you believe that and I respect your viewpoint even though I do not agree with it.
Touch DNA has long been proved as credible for many years and suspects have been arrested and convicted when touch DNA evidence was left behind. The touch DNA held up on appeals as well.
I haven't seen any proof this was transference. It is very consistent with it belonging to the murderer of JB especially the specific locations where the same male DNA was found on her garments.
With all due respect (and I do appreciate your input and civility here), I want to point out that while you are correct in many ways, you are neglecting the known pitfalls of DNA and especially tDNA.
Below are some articles from reputable sources detailing the science behind tDNA and providing several cases in which tDNA played a role in wrongfully convicting someone. But first, it's critical to remember that while we have the technology to extract tDNA, we don't have the scientific knowledge to fully understand its meaning. When tDNA is found on a body or in a crime scene, it does not automatically mean that it belongs to the killer.
Finding DNA is science, but interpreting it and its relevance in a crime is subjective.
Further, the reliability of the tDNA depends on the lab, technicians, and their standards of practice. The tDNA in JBR's case was only tested once, and several items relevant to the crime (such as the cord, garrote, and flashlight) were never tested at all. Newer, more sensitive technology exists that could improve the quality of the tNDA sample that was found and potentially find more.
What's the harm in retesting, especially if it could provide better and more samples? Wouldn't that benefit everyone, regardless if IDI or RDI?
In JBR's case, there are several unidentified profiles found on her body, clothing, and elements of the crime scene. Fiber evidence, fingerprints, and complete DNA of the family were also found.
Why are two samples of microscopic, incomplete tDNA (alleles were added in the lab to make the sample complete enough for calling it an actual profile) more compelling than any of the other biological evidence?
I am not saying that that the tDNA is insignificant, but I don't think that the case hinges on it to the exclusion of all the other evidence that points in another direction. Additionally, it is hard for me to argue that the tDNA is irrefutable proof of an intruder when so many experts have risked their reputations stating otherwise.
One little example about DNA testing in JBR's case that gives me additional cause for concern: The ME admitted to using clippers on JBR's fingernails that had not been sterilized and had been used on other bodies before hers. This contaminated the DNA found under her fingernails and resulted in several different profiles being located.
If there was this amount of contamination during the autopsy, then we can't be certain that biological evidence collected from her body and clothing during that examination wasn't also contaminated. We simply can't be sure, and in lieu of certainty, we can't say that the matching tDNA profile convicts or exonerates anyone. This tDNA by itself would never hold up in court.
