Conclusions (1)

In conclusion, there is no evidence of cellular material in the samples analyzed with the cytocentrifugation technique and coloration with hematoxylin.

Some samples (A-E-F-H-I) and in particular sample “H”, show granules with a characteristic circular/hexagonal morphology and a radial central structure. A more detailed microscopic study, along with a review of the data present in the literature, allowed it to be determined that the structures in question are attributable to starch granules: therefore material of a vegetable nature.

Taking note that no DNA suitable for further laboratory investigations (amplification, electrophoresis) was present either on the swabs [tamponature] (A-B-C-D-E-F-G-H-I) taken from Exhibit 36 (knife) or on those (L-M) taken from Exhibit 165B (hooks of the bra), the experts verbally informed the consultants of the parties that they would proceed to a detailed examination of the Technical Report drawn up by the Scientific Police, as according to the task formulated during the assignment hearing.

Before tackling the second part of the assignment given to us, we consider it appropriate to give an outline [cenni] of the forensic methodology applied for investigative purposes, a methodology which can be summarized in the following steps: 1) define the crime scene; 2) reconstruct the way in which the crime happened; 3) collect elements used for the purposes of identification; 4) send the items to the laboratory for expert analysis.
