If both of those pieces of evidence are ruled out, then the question is what the judge thinks about the contested shoe print in the room and the contested bare foot print in the bathroom. The Messai report seemed to concede the footprint in the bedroom was up for grabs, but it states that the footprint in the bathroom was not.
Also if the court is requiring you believe there are multiple people (because of the nature of the attack) and requiring you to believe that there is a cover-up then you would note that only Amanda's bare prints are flourescing in the house and no other. Therefore the evidence tilts that the other person is Amanda. I believe the Messai report stated it was up for grabs if the murder could have been committed by one person or multiple people, it was the DNA on the knife that required multiple people, multiple knives.
I disagree with others that "false confessions" and even a tendency to lie to police and in the courts, means one is connected to the crime. Actually if that were true, then Kokamani is the likely accessory as there is evidence he was near the cottage, saw the broken down car out front, and lied when he said Amanda was there throwing olives at him. Ergo, he is lying as part of a cover up that he was there.
