Mark Harrison certainly knew what he was talking about...and this is what he said...
Additionally I consider no inference can be drawn as to whether a human cadaver has previously been in any location without other supporting physical evidence.
perhaps you and others should take note
But take note also that LCN DNA profiling, as its techniques improve, could yet establish that Madeleine McCann WAS the source of the body fluids in Swab 3A.
It must not be assumed that we will not, one day, find confirmation that those WERE her body fluids.
Even D C I Redwood of Operation Grange said there was EVIDENCE that she might have died 'in the apartment' - that was in a statement he made in early 2013 IIRC. That means
'before her body was removed from the apartment'.
Think about it.
What evidence would that be, I wonder??? -------------------------------------

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 profiles of many of the scientists here in Birmingham, 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?
