Firstly, here are the last three results you are expecting
An incomplete DNA result was obtained from cellular material on the swab 3a. The swab contained very little information and showed low level indications of DNA from more than one person. However, all of the confirmed DNA components within this result match the corresponding components in the DNA profile of Madeline McCann. LCN DNA profiling is highly sensitive, it is not possible to attribute this DNA profile to a particular body fluid.
There is no evidence to support the view that Madeline McCann contributed DNA to the swab 3B.
A complex LCN DNA result which appeared to have originated from at least three people was obtained from cellular material recovered from the luggage compartment section 286C 2007 CRL10 (2) area 2. Within the DNA profile of Madeline McCann there are 20 DNA components represented by 19 peaks on a chart. At one of the areas of DNA we routinely examine Madeleine has inherited the same DNA component from both parents; this appears therefore as 1 peak rather than 2, hence 19 rather than 20. Of these 19 components 15 are present within the result from this item; there are 37 components in total. There are 37 components because there are at least 3 contributors; but there could be up to five contributors. In my opinion therefore this result is too complex for meaningful interpretation/inclusion.
Why?...
Well, lets look at the question that is being asked
"Is there DNA from Madeline on the swab?"
It would be very simple to say "yes" simply because of the number of components within the result that are also in her reference sample.
What we need to consider, as scientists, is whether the match is genuine and legitimate; because Madeline has deposited DNA as a result of being in the car or whether Madeline merely appears to match the result by chance. The individual components in Madeline's profile are not unique to her, it is the specific combination of 19 components that makes her profile unique above all others. Elements of Madeline's profile are also present within the the profiles of many of the scientists here in Bimiingham, myself included. lt's important to stress that 50% of Madeline's profile will be shared with each parent. It is not possible in a mixture of more than two people, to determine or evaluate which specific DNA components pair with each other. Namely, we cannot separate the components out into 3 individual DNA profiles.
Therefore, we cannot answer the question: Is the match genuine or is it a chance match.
The same applies to any result that is quoted as being too complex for meaningful inclusion/interpretation
What questions will we never be able to answer with LCN DNA profiling?
When was the DNA deposited?
How was the DNA deposited?
What body fluid(s) does the DIVA originate from?
Was a crime committed?
These, along with all other results, will be formalised in a final report

Re: Abduction of Madeleine McCann on 3rd May 2007
A DNA profile has been obtained from the reference samples of Kate HEALY 51162896) and Gerald McCANN (51162897).
A DNA profile has also been obtained from a pillowcase (SJM/1).
DNA profiling reveals a series of bands, half of which a child inherits from their natural mother (maternal) and half of which ït ïnherits from their natural father
(paternal)
In this case, all of the bands present in the profïle of abtained from the pillowcase are represented in the combined profiles of Kate HEALY and Gerald McCANN. This is what I would expect to find if the profile obtained from the pillowcase originated from a natural child of theirs.
The results of the DNA profife obtaïned from the pïllowcase is approximately 29 million times more likely if the profïle originates form a natural child of theirs rather than someone unrelated to them.
In my opinion, the results detailed above provide extremely strong support for the view that the profile obtained from the pillowcase originated from a natural child of Kate HEALY and Gerald McCANN.
Please note: I understand that the McCANN's have a second female child. It therefore remains a formal possibility that the DNA on the pillowcase could have originated from her as the genetics would be in keeping with those described above.
If I can be of further assitance or you require a CJA statement please do not hesitate to contact me at the laboratory on 01XXX XXXXXX.

Re: Abduction of Madeleine McCann on 3rd May 2007
A DNA profile has been obtained from the reference samples of Amelie Eve McCANN (SBM/2) and Sean Michael McCANN (SBM/3).
In this case, all of the bands present in the profiles of both Amelie McCANN and Sean McCANN are represented in the combined profiles of Kate HEALY and Gerald McCANN. This is what I would expect to find if Amelie McCANN and Sean Michael McCANN were their natural children.
Neither the DNA profile of Amelie McCANN nor Sean McCANN matches that from the pillowcase (SJM/1) and therefore in my opinion, neither Amelie McCANN nor Sean McCANN can be the source of this profile.
