Even in the visible bloody shoe print trail of Guede there are prints missing. The print where he stepped in blood is missing, no prints where he walked through the door, and a print in front of Knox's room is missing. Where did these prints go?Thank you. Guede would have made four trips between Meredith's bedroom and the bathroom if we believe that he got towels and he washed his clothes. If he only got towels, there would be fewer prints. If he didn't get towels, there would be no prints. There are no prints. If Knox boogied down the hall on the bath mat, there would be blood on the bottom of the bathmat, but this would not remove luminol evidence of prints.
However, it doesn't end there. After having her boogie on the bathmat to her bedroom, we have her standing barefoot in front of Meredith's bedroom door, but now she has fruit pulp, iron rich water, or bleach on the bottoms of her feet.
IMO. This is all explained by the cleaning evidence, the bloody female shoe print on the pillow, and the lamp on the floor. They were not cleaning 'DNA' but prints. In the process of cleaning these prints a few of Guede's prints had to be cleaned as well.
