Here is the quote:
At a meeting in our office, with the Portuguese and the English investigation team, Stuart expresses his disappointment over the test results. This is where the saga of the FSS reports begins. We read the part of the report dealing with the traces of blood lifted from the floor of apartment 5A, from behind the sofa and in the boot of the McCanns' car
and we don’t agree with Stuart’s disappointment We talk about blood traces because the CSI dog is trained to find only that bodily fluid. The reports that support that decision are clear: the CSI dog was used to detect human blood. Low Copy Number, the technique used to determine the DNA of the samples, does not identify the nature of the bodily fluid they are derived from. But we know it's definitely traces of blood and not other bodily fluids since the CSI dog is trained to detect only human blood.
In the first case, the laboratory considers that the result of the analysis is inconclusive because the samples gathered provide very little information when the DNA comes from more than one person. But all the confirmed DNA components match with the corresponding components in Madeleine’s DNA profile!.
As for the second case, after an explanation about the DNA components in Madeleine's genetic profile, it concludes that 15 out of 19 markers in Madeleine's profile are present in the sample examined. Only 4 short of 100% reliability. The FSS specialists qualify the results as, "complex," and state that these 15 markers are not enough to conclude with certainty that it's definitely Madeleine's DNA profile, especially as Low Copy Number picked out a total of 37 in the sample. That means that at least three individuals contributed to this result.
But there was more in this first preliminary report. In the same report, the scientist went further and explained that in the profiles of many of the lab experts, elements from the DNA profile of Madeleine are present. This means that a major part of the DNA profile of any given person can be built by three donors. That is understandable. Two questions arose immediately. The first one: what good is a DNA profile in terms of criminal evidence, if it can be the combination of three or more donors? Another question was simple: why did the DNA profile from those three donors contribute to Madeleine’s DNA profile and not to that of any other person, like the scientist who carried out the test? But the surprises from the preliminary reports were not to end there.
On the very day that interrogation of the McCann couple starts, a second preliminary report reaches us. Contrary to the first report, it accords more importance to the DNA profile of the blood lifted from the floor of the apartment. In that sample, the DNA came from more than one donor, but the confirmed DNA components match the corresponding components of Madeleine's DNA profile.
As for the samples lifted from the boot of the car, there is no further mention of the 15 markers, as if they had never existed.
Suddenly, light was starting to be cast on the issue:either this LCN technique is not reliable or it's simply much easier to explain the presence of Madeleine's DNA in the apartment than in the boot of a car hired 24 days after her disappearance.
At our insistence, Stuart contacts the FSS and asks them if they think the Portuguese are idiots. We hear him saying: "With a lot less than that, we would have already arrested someone in England." I look at my colleagues and see that they are as stupified as I am. In fact, in Portugal, it's not so easy to arrest someone. We explain to Stuart that the McCanns interrogations would not result in detention. According to Portuguese law, the crimes of concealment of a corpse and simulating an abduction are not liable to remanding in custody.
