Moreover it has been assumed that it could have took place an involuntary contamination. It is to be considered, at least in this phase, as proof lacking of value. In fact, it is not seriously contestable that the DNA extracted from the examined material is related to the victim, provided that also a compatibility judgment confers meaning of certainty, considered that the comparison should be carried out in the picture of the narrowest microcosm, due to the infinitesimal number of visitors of Raffaele's room. Neither the merely conjectural value of the envisioned contamination can be avoided, considered that the operations have been carried out with guaranteed procedures and according to the leges artis. From this, comes that that knife has to be related to that only moment when it would have been used against Meredith, which is to say during the murder.

14 - It has also to be observed, that the cause of the woman's death has been contested by the Amanda's defense, according to the results provided by an expert consultancy. In fact, it has been advanced on the base of some elements taken from the same assessments completed by the technical-legal consultant, to begin with from the not modest presence of blood in the corpse, from the type of observed postmortem lividity, from the petechiaes in the orbital zone and also from the numerous ecchymosis on the mandibular region and under the chin, from the nature and characteristics of the aforementioned and from the fracture of the hyoid bone, that the death of the women would have been caused by choking, associated [end p the 15] with the slitting of the throat by means of a bladed weapon, all carried out by a subject, presumably of male sex, endowed with the necessary force. But actually, none of the proposed elements is able to deprive of causal or co-causal relevance the deep neck wound on the left laterocervical region, such as to produce a path of eight centimeters and also the severing of the interested musculature and the thyroidal artery. Indeed Meredith has been found on the floor within a lake of blood, present only to the height of her head, indicating the spacial position of the point in which the young women died. It has also to be said that neither the ecchymosis nor the fracture of the hyoid bone are suitable to give a precise explanation of the event, even if worth to represent the violence exercised on the body, of which all the damages found on it constitute expression, included the oral cavity, the lips and the gum. It is wanted to be said that the poor Meredith fell victim to one or more executioners, whose without mercy won over her attempts of resistance also exercising pressure on her neck, therefore producing the aforementioned lesions, and finally striking the mortal blow carried out with a presumably single edge knife which produced the observed wound and the consequent hemorrhage. It is not considered that the death, presumably occurred around 10 PM, came much later, with regard to the circumstance and the cutting of an artery. On the other hand, it is unavoidable that an asphyxia phenomenon had occurred, considered the bleeding produced by the aforementioned wound. It has to be added, logically, that the reconstruction proposed by Amanda's defense advisers is completely incongruous, focused on the twofold violent action, without and understanding of the reason of the use of the second one during the development of the first. The pressure applied on the neck, attested by ecchymosis and fractures of the hyoid, had instead an instrumental nature, aimed to immobilize the victim.
