Yes - the argument has been made elsewhere that the blood was "deposited over" an existing DNA sample already on the t-shirt after fresh laundering, and was Jodi's blood.
I think this suggestion was put because the sample was claimed to be a "mixed" sample with male and female DNA, but it is not reported in the results as such.
Where a mixed male/female sample is indicated, the first column shows:
XX
XY
If it was, for example, a full profile from Jodi, with a partial sample from a male, the "numbers" for Jodi's sample would be recorded at each marker (as the XX, or female markers) and the "unknown" male markers would be placed in brackets to differentiate them.
Like this:
XX
|1,2|3,4 (22)|5,6 (23,24)|7,8|9,10|11,12(25,26)|13,14|15,16|17,18 (27)|19,20|Jodi Jones& unknown male
XY
In this example, the numbers in bold are the "full match" female profile, the numbers 22 - 27 in brackets are the additional, male components in the sample.
The sample we're talking about is labelled simply XY - a male sample. There are additional markers, which should indicate that this is a mixed male sample, yet it is entitled SK and JJ.
However, some of the additional markers (or partial markers) are in brackets - the usual way of differentiating male/female - and some are not. (Doesn't need me to say the DNA results were a shambles!)
Two points to be made about this - of the additional markers, outwith Kelly's own, (there are ten of them out of the 20 required for a full profile), if they were female in origin, then JaJ (9/10), JuJ (6/10), YW (6/10) and AW (3/10) "could not be eliminated" as contributors.
Therefore, the existence of those other indicators means the blood cannot be claimed to originate from Jodi, especially if the "deposited over" theory is being used. The t-shirt was claimed to be JaJ's, AW did her washing, she spent time with YW, and JuJ is her mother - DNA from any of these other females could be innocently explained as being left over on the T shirt after washing (or even deposited there after washing) - what it cannot do is indicate decisively, that the blood on the t-shirt, in which these markers were found, was Jodi's.
Looking at these, I've just found something very interesting with the possibilities (apart from probably every male closely associated with the case (including police officers and the pathologist himself) coming out "could not be eliminated") - that, in itself shows how careful we have to be a about claiming matches from mixed profiles.
There is a particular marker in this sample that appears in only 4 of the profiles in the defence papers. Two of those are definitely eliminated as suspects for other credible reasons. Which leaves 2 - we know SK is one. The other is DD. It's interesting that this "unusual" marker (unusual in the sense that it only appears in four profiles whereas a "common" marker from the same batch of profiles appears 48 times, another appears 58 times, etc).
Of the 3 unbracketed indicators in the "additional" profile, DD's profile could be claimed to account for two of them. The remaining bracketed indicators may be female in origin, simply because they are bracketed.
If we look at those two profiles in combination, they share identifiers at 9 places. So, technically, this sample has a claimed full match to SK, but could also be claimed to match DD at 11/20 points (two of those showing as "additional" markers in the original profile). Of course, we could never claim a "match," nor should we, but the existence of this one unusual marker in the DNA profiles available, the fact that it turns up in the only full DNA profile connected to the crime (at the time), and then appears in the profile of someone else closely connected to the case, whose movements, explanations, etc, left a lot to be desired should, at the very least, have had investigators looking a little more closely, I would have thought.
