This Court also considers that the components of the mixed trace specimens were deposited simultaneously, and were deposited by Amanda.
Against this conclusion, the observations with respect to the shared use of the bathroom by the two young women, the resulting likelihood of their biological traces being present, and the way in which these specimens were gathered [by the police], are not valid, in the sense that they are not considered either convincing or plausible, neither in relation to the overall situation present in the bathroom, which has been described, nor with [regard to] the statements made by Gioia Brocci and by Dr. Stefanoni, who both stated that the trace specimens present in the bathroom and in the bidet were of the same colour, as of diluted blood, and appeared to constitute one single trace, one [part] in the bidet and one in the sink. The drop at the top [302] and the drop at the bottom had continuity and formed a continuous pattern.
The specimens were collected accordingly, just like any other specimen which necessarily occupies a certain space, and which the technician does not collect one little spot after another.
It should also be noted that the statements according to which the traces in the sink and in the bidet each constituted a single specimen correspond to the act of cleaning the victim’s blood, an action previously mentioned and during which it would have been easy to leave a mixed sample, constituted precisely of biological material from the victim (blood) and biological material from whoever was cleaning (cells lost during scrubbing/rubbing).
It should further be noted that such mixed trace specimens, with the morphology shown, were found both in the sink and in the bidet.
It should be considered that those in the sink occurred when Amanda, as has been said, washed her hands which were stained with Meredith’s blood; in the bidet it should be considered that they [the traces] originated from a similar activity, but in relation to the feet, which must also have been covered with blood as can be inferred from the print of a bare foot left on the sky-blue mat, stained with Meredith’s blood.
