The Nencini Papers

Day 3, 30 October 2013

Berti and Barni of the RIS have tested the LCN DNA sample 36-I and have filed their report.

The subject of the question, as formulated in the body of the assignment minutes of the assignment, recites the following:

“Examined the documents of the case and in particular the findings of the expert report submitted on 29 June 2011 by Prof.ssa Carla Vecchiotti and Prof. Stefano Conti, together with the statements formulated by the consultants of the parties Dr. Patrizia Stefanoni and Prof. Giuseppe Novelli in their papers filed at the hearing on September 6, 2011, and provided the analysis of the sample previously worked, the peritians say about the attribution of the track marked with the letter (I) found on the finding no. 36 and if DNA itself can be identified as referring to Meredith Kercher or the condemned Rudi Herman Guede.

In the event that the sample is not possible for failure to perform, poor conservation or any other cause, the pertinent experts will give the Court of Justice immediate notice by fax.”

The document is in the form of a laboratory report and is highly technical.  The key finding is the following:

The comparison between the genetic profiles of the trace I and the genetic profiles of the comparison subjects and the subsequent biostatistic analysis allowed to find:

  • a high degree of compatibility. statistically supported. between the genetic profile of Amanda Marie Knox and the genetic tracers of the I track;
  • a high degree of incompatibility. statistically supported, among the genetic profiles of the remaining subjects (Meredith Susanna Cara Kercher, Rudy Hermann Guede, Raffaele Sollecito) and the genetic profiles of the trace I.

In plain English, the Sample 36-I is neither starch nor rye bread and is compatible with Amanda Knox.  There is incompatibility with Meredith, Guede or Sollecito.  It also demonstrates that the sample was not ‘too low copy number’.

The court will convene on 6 November 2013 to have the report entered into evidence.

Predictably, the US press erupts with headlines about how ‘the DNA on the knife is not the victim’s’ as though the sample 36-I near the handle cancels out the one lower down on the blade, a completely different sample, 36-B, which shows a near full profile of Meredith Kercher (15 alleles).  New York Daily News is typical:


The knife was used for cooking, not killing.

Stunning testimony in the third Amanda Knox trial revealed Wednesday that new DNA found on the purported murder weapon belonged to the suspect — and not the victim.
