Sorry about the technical nature of this post - this is the nearest I can get to the confirmation Lithiam has requested - the following results are taen verbatim from the reports.
I can’t give the full reference numbers from these reports, so will identify them my partial references.
Forensic report **12/03 (undated) – “Biology joint report” P 26 of 39:
Boot (2) (left) Labelled “Taken from Luke Mitchell 1st July 2003”
Jeans (Labelled as above)
Belt (Labelled as above)
Sock (1) (Labelled as above)
Sock (2) (Labelled as above
No blood was found on these five items.
Same report, P28 of 39
Trousers (1) labelled “*** Newbattle Abbey Crescent, Dalkeith 4/7/03
White stain 305B, on the upper back left pocket flap was tested for a chemical found in saliva.... none was detected... 305B contained a sperm head and many nucleated cells, some of which had the microscopic appearance of a cell type found within the vagina.
Table of Results, ref **22/03 Appendix II, p4 of 16 – Stain 305B, match with Jodi Jones.
So, yes, a single DNA result, found on a pair of Luke’s trousers, was found to be a match with Jodi. However, this sample was found on a pair of trousers taken from Luke’s room 4 days after the murder – there was nothing to say when those trousers had last been worn, there was no blood or other forensic traces from Jodi on them, they were not considered to be connected with the crime scene in any way, and the cells, some of which “had the microscopic appearance of a cell type found in within the vagina” were never properly identified.
All of the clothing taken from Luke in the early hours of July 1st returned no results for DNA from Jodi.
Reference **22/03:
10 H Semen, labelled “i/s back L sleeve of piece of shirt (2) comprised 2 samples –" Each sample was processed in such a way as to separate any sperm from any cellular material present."
This is how all of the samples labelled “semen” were treated before being analysed.
10G – Blood, labelled “o/s front piece of shirt (2).
Appendix II, Table of results ref **22/03 - 10G, Blood – match to S.Kelly (+Jodi Jones).
Those are the results, exactly as they appear in the forensic reports – 10G is a full male profile, with 8/20 markers for the minor contributor, named in this result as Jodi.
10G does not contain any description of samples being processed to separate sperm heads from cellular material, as 10G was not labelled (or considered to be) a sample containing semen or sperm heads - it was labelled as, and treated as, a bloodstain.
(I posted this already and then deleted it, because I had typed it out first in word and was copying and pasting it here, but the spacing was all wrong - instead of repositioning the various bits and pieces, I accidentally posted too soon.)
