Why do you feel the need to lie, Mach?
7th April 2011 – message from Stefano Conti to the Judges of the Court:
For the kind attention of the illustrious Mr. President Dr. Hellmann and the illustrious Mr. advisor Dr. Zanetti
We kindly request the illustrious Mr. President the authorization for the handing over of the following documentation that should be in the court records:
CD of the electropherograms
CD RAW DATA (data relating to the electrophoresis run generated by the automatic sequencer)
All the records, in all phases, of the depositions of Dr. Stefanoni and of the technical consultants for the parties (CTP), including the documentation deposited (considerations and notes, including any CDs that there may be).
CD of video, photo, sequester report, methods of collection, conservation and transport to the Scientific Police laboratories relating to the seizure of the knife in Sollecito’s home, including the transcripts of the depositions in all their phases.
If the data, even partially, is not found in the court records or not received and/or not submitted, kindly, taking into account the complexity of the evaluation, given that they are an integral part of the analysis carried out on the two exhibits and given their importance in being able to fully respond to the task required of us, we request that they are made available for collection at the laboratories of the Scientific Police, through an official communication.
Thank-you for your kind attention,
On behalf of the assessors,
(Professor Stefano Conti)
20th April 2011 – message from Dr. Stefanoni to Judge Hellmann:
On 7th April 2011 the expert assessors, as signed by Professor Stefano CONTI, you received a request to authorize the handing over of technical documents relating to the findings on the subject of forensic analysis performed by yours truly and documented in the report dated 12th June 2008.
The request that you received (which I attach for ease of reference), authorizes the expert assessors for this acquisition, even in the case of documents not produced at that time and so not available in the court records.
Among the documents requested, that which specifically interests the technical activities performed at the laboratories of this office, are found to be the following:
CD of the electropherograms;
CD RAW DATA (data relating to the electropherogram runs generated by the automatic sequencer).
In relation to the request to receive the CD containing a collection of DNA profiles (in the form of electropherograms), we wish to inform that a copy has already been submitted to the court records on 25th September 2008 to the preliminary trial of Dr. Paolo Micheli of the Tribunal of Perugia and all the electropherograms relating to the genetic profiles extrapolated from the technical analysis were collated in a separate attachment from the main body of report.
In relation to the request to receive the CD RAW DATA, we are obliged to report that the information in the form of files present in the sequencer are never an integral part of the technical report, in that the evaluation by the forensic scientist, and therefore the DNA profile, is already represented by the printed electropherogram, attached to the technical report on which all the usable data for an evaluation of a genetic profile.
In addition it should be remembered that the files contained in the sequencer named “Sample File.fsa” contain sub-folders named “Info”, “Raw Data” and “EPT Data”, that don’t permit any kind of human intervention to modify and/or add data, and therefore, their viewing, does not contribute in providing additional elements for the evaluation of the genetic data.
Finally, we would inform that the request made by the expert assessors relating to the handover of the CD RAW DATA is incomplete in that the name of the “sample file” requested has not been specified, without which it’s not possible to precisely identify the documentation being requested for handover.
Remaining at your disposal for any clarification on the matter, with best regards,
Technical Consultant,
Dr. Patrizia Stefanoni.
July 25, 2011, Vecchiotti Testimony p128
Prosecutor: So, do you think this is enough time to avoid the risk of contamination in the laboratory, the fact that for 12 days no sample had been analyzed, no sample containing Sollecito’s DNA had been analyzed?
Vecchiotti: It’s enough time
Prosecutor: Did you examine the negative controls relating to this sample?
Vecchiotti: They were not attached.
Prosecutor: To what?
Defense Ghirga: We continue to say, excuse me…
Vecchiotti: The negative controls were not attached.
Prosecutor: What were they not attached to?
Defense Ghirga: Your honour if you’ll let me speak…
Vecchiotti: To the electropherograms
Defense Ghirga: … if they are the negative controls from this morning, we still don’t find them eh.
Prosecutor: What do you mean from this morning?
Judge Hellmann: Yes we checked for them at the hearing on this matter…
Defense Ghirga: We didn’t find them there either your honour.
Judge Hellmann: Which was the 8th October if I’ve understood.
Vecchiotti: I have the electropherograms that were sent to me on the 8th October and they’re not there…
Prosecutor: In a moment let’s have a look at the delivery note. But even if you didn’t find them didn’t you feel the need to ask Stefanoni for them?\
Vecchiotti: I asked Dr. Stefanoni twice for the electropherograms taking for granted that she would have included them.
Prosecutor: That she would have included the electropherograms for the negative controls?
Vecchiotti: No that she would have… that in the electropherograms there would be the samples, there would be the negative controls, because why shouldn’t they be there?
Prosecutor: Yes but when did you notice that they weren’t there…
Conti S: We asked for them again.
Prosecutor: Because then you’d have noticed that they weren’t there, right?
Vecchiotti: It’s obvious but it’s her responsibility to attach them, because why do they need to be asked for? It shouldn’t be necessary to ask for them.
Prosecutor: You’re the expert Doctor.
Vecchiotti: Look they don’t need to be requested in that case, they should be produced by the those who have them.
Prosecutor: Is this also an international rule, universally recognized?
Vecchiotti: That the negative controls are included, yes.
Prosecutor: Whatever, they should be included, and one time they forget to include them but they exist…
Conti S: They were requested twice.
Prosecutor: …it’s good practice for the expert to ask for them…
Conti s: In fact we asked for them twice.
September 06, 2011, Stefanoni admits she didn’t provide the raw data to the independent experts. p253
Dalla Vedova: The raw data, several times our consultant asked us to request for them to be submitted and we did so, can you tell us in a few words what this raw data is and if this data is available today in the case files?
Stefanoni: So, the raw data is not available in the case files, because they were never, let’s say, handed over. I can explain what they are…
