The DNA analysis is a shambles, labelling,instructions and so forth its impossible to say what they meant , the samples that proved a match swere all to one person but the other samp!es cannot be ruled out as his either.
Two full DNA matches were recovered from the scene - one was SK, and was found on Jodi's T shirt. The other was JaF and was found in the condom found "within a 50 yard radius of the body." Neither can be ruled out as contributors to the partial/mixed samples, neither can they be claimed to be contributors.
The condom was initially recorded as having been found "20 yards from the body" (although no direction was given) - how this morphed into such an ambiguous phrase as "within a 50 yard radius" is anybody's guess.
I believe the SCCRC only re-tested the trousers, and found further DNA (which was missed during the investigation) on the zipper and inside of the button hole. What the SCCRC does not appear to have sought is any sort of explanation for the dozens of tests which came back "inconclusive" or "no reportable result." Unless it is known what they were asked to report about it can never be known if there would have been reportable results for other factors - contrary to popular belief, the lab are not given samples and asked to "test for everything" - samples are sent with specific instructions.
For example, there was one report in the case papers regarding hair analysis. The report states that the lab had received hair from Jodi Jones and Luke Mitchell. All that report could say was that the hair attributed to Jodi appeared, in fact, to be Jodi's, and none of the hairs found on her "matched" Luke's. What it did not (and could not) say was whether the hair that was not Jodi's "matched" anyone else's hair - the question was simply not asked.
I realise "matching" hair samples is not a technically correct term, but I have been pulled up before for responses which have been too technical, so have kept this simple.
