Documents disclosed in the midst of the trial reveal that the prosecution engaged in a massive suppression of DNA evidence relevant to the case. Indeed, the prosecution suppressed in excess of 100 out of 173 genetic profiles that the laboratory processed in just the first month of the investigation. The suppressed results are for batch controls and evidentiary samples, including rape kit evidence and evidence of an additional crime scene in the downstairs apartment. Most critically, there has been a suppression of almost all evidence relating to the time period and batch in which the controversial Rep. 36b (allegedly the murder weapon) was processed, with the available data (and missing data) strongly suggesting that there was a serious problem in the processing of this trace. The prosecution’s suppression of this data deprived the defendants of a full and fair opportunity to investigate laboratory contamination and to examine potentially exculpatory genetic evidence. The concealed records prove a pattern of contamination and improper laboratory practice that eviscerate the prosecution’s key evidence against the defendants.
The analysis shows:
The prosecution hid the results of early and decisive DNA tests excluding Raffaele Sollecito as the sexual assailant, securing on improper grounds the pre-trial incarceration of Sollecito and Knox (and Lumumba) to the severe prejudice of the defense;
The prosecution concealed the initial results for tests performed on the two key items of evidence, i.e., the kitchen knife (Rep. 36b) and the bra clasp (Rep. 165b), and instead, produced only the results of suspicious “do over” tests (re-runs), without disclosing the data from the initial tests or even the fact that the subsequent tests were “do overs”;
The prosecution concealed that the kitchen knife profile was generated within a set of tests for which 90% of the results have been suppressed, strongly suggesting the occurrence of a severe contamination event that the prosecution continues to hide;
The prosecution claimed that contamination of the bra clasp was impossible, even though the bra clasp profile was produced during a set of tests for which there is documented proof of contamination;
The prosecution falsely portrayed the DNA laboratory as pristine and perfectly maintained, even though the lab’s own documents demonstrate that it was plagued with repeated contamination events and machine malfunctions that were known to the lab;
The prosecution has withheld the results from a massive number of DNA tests (well over 100), including probably exculpatory profiles relating to the sexual assault and a secondary crime scene downstairs;
The prosecution has hidden all of the records of the DNA amplification process—the most likely place for laboratory contamination to have occurred—including all of the contamination-control tests for this process.
This is the "Sequestration Note" concerning only Lumumba's mobile phone and SIM Card.
