But in this phase it can be concretely observed a full compatibility between the imprint and the sole of Sollecito's shoe, which actually induces to exclude the possibility that that imprint could have been left by the analogous shoe size 45 used by Guede. It is a fact that, given the non-distinctiveness in the sphere of that type of shoes, nevertheless in the microcosm object of observation, the found compatibility constitutes an element that it is worth to confer concreteness and therefore to assert the accusatory hypothesis related to the presence of Sollecito on the crime scene. The fact that during the analysis of some samples of the sole has not been retrieved any biological material related to the victim, does not seem decisive in a contrary sense. It constitutes a fact to be considered and indeed to be taken for granted, that the evening of the happening had been carried out a frenetic washing, that also interested the shoes of the suspects.

It has been subsequently carried out at first a search among the files present in the hard drive and then through the non-allocated clusters, that is the part containing information relative to files not available for the operating system, because previously cancelled but still recoverable. In such perspective it has been carried out a research to find human interactions in period of time around 6 PM of the first November and 8 PM of the 2nd of November. Such analysis has produced a negative outcome regarding modified or cancelled files The search of created files has allowed to verify that in the considered period had been created nine files, of which two at 3:15: 07 from the automatic system and the others automatically generated by the navigation browser Mozilla Firefox in its cache, all files are characterized by the fact that they have been created at intervals of 60-120 minutes from one another. The search for written files has allowed to assess that during the examined period had been produced 17 files of which one inside of a damaged cluster, 8 related to files automatically written by [end p the 27] the Mozilla Firefox browser, 2 automatically generated by file sharing programs at the completion of the download from the net, 3 related automatically generated system logs and 3 related computer crashes of audio/video reproduction programs. These last ones turn out to have been written by the VLC software at 5:32 AM in three subsequent moments.
