That is what Mark Perlib claims; that he can seperate mixed samples and show how nany contributors there really were and which alletes belong to which person. So he could say how many people were represented in the mixed sample from the boot and which markers belonged to each person. I don't know if that would shed any light on the case, but it could answer the question of whether Madeleine's DNA was in the boot of the car.
Maybe the computer could work out how many people were in the mix, but how it could know the markers for each person is beyond me. How on earth would it know which markers belonged where? Ok they have Madeleine's DNA from which was found 19 markers I believe. Now if they were searching for the rest of the markers, how would the machine know which markers were hers, even if it was found to have the rest of the markers in her DNA they could also belong to other people who are in the mix, do you see what I mean? Madeleine would share markers with her family and also with the general public.
