That this action of cleaning could have been carried out the same night, immediately after the murder, seems difficult to hypothesis e. To linger on in the house where Meredith’s body lay could have been risky. On the contrary, returning in the morning would have allowed [them] to do the cleaning under better conditions and with more time available; it is also possible that more cleaning products were needed, as the visit to Quintavalle’s shop leads us to believe. Furthermore, once the mobile phones had been taken, and the door had been locked, there would have been no compelling reason not to put off the cleaning until early the next morning. If anyone had arrived at the house (Silenzi, for example) the closed door would have convinced him or her that Meredith was not in her room, and the impossibility of hearing Meredith’s phones ring would not have given rise to any suspicion. Nor is it held that what was presented with reference to the cleaning activity and the
prints elimination is contradicted by the prints that were actually found and this with particular reference to the prints of shoes left in the corridor. In this regard, [416] it can in fact by hypothesised that the cleaning action was not particularly careful or else - and this second hypothesis is held to be more probable since the shoe prints, as has been recalled, were fairly evident - that such an omission was intentional, in the knowledge that, having been in Meredith’s room, when the latter was killed, with bare feet as has already been noted, the shoe prints in blood would have constituted an exonerating element in their defence.
