too many assumptions
You are making a number of assumptions. I think that the laboratory in which the work was done, was not yet accredited, so your premise is already open to question. Second, whether the blade or the handle was sampled is not yet entirely clear, if I follow the discussion here and elsewhere correctly. Third, even if it were the blade that was sampled, how can anyone be certain where it was sampled? Perhaps the independent scientists chose to sample it elsewhere, a perfectly reasonable thing to do. Fourth, let us assume for the sake of argument that Meredith’s DNA arose from contamination on the first knife profile. In that case the DNA giving the present signal could belong to anyone. Fifth, true LCN DNA profiling, not just DNA profiling that happens to fall into the low template range, is always done at least twice, because of alleles dropping in and out. Why make the assumption that alleles dropping in/out will not be observed here?
Finally, there is one thing that has always bothered me about the knife. As one travels from left to right along the x-axis the peaks are at least as tall on the right hand side as on the left. This strikes me as odd if the knife were cleaned with bleach. What does your common sense tell you?

The procedure that Stefanoni used to amplify the DNA was most certainly not "commonly accepted." Whether or not Stefanoni used commonly accepted procedures subsequent to this portion of the work was disputed by Tagliabracci.
pilot padron,Again, admittedly from one with limited experience with the complexities of vertical gardening, may I proffer a common sense question as a reply.
If a professional accredited technician removes *most* of the only batch of dna that existed,
and this small batch was *all on one small particular area* of a knife,
and then using commonly accepted scientific procedures identifies *one* person from that sample.... .
Why would a usually very knowledgeable poster
who in the past has endowed the writings of the vertical gardener with the credibility and authority comparable to the stone tablets delivered by the Almighty to Moses,
express the above suggested bewilderment as to whom *the remainder* of that small (untestable) batch belonged ?
