The defence have not disputed that Meredith's DNA was found on the tip of the alleged murder weapon - they have only claimed that it was contaminated. Even if it wasn't AK's DNA on the handle, why was a knife with Meredth's DNA on the tip found in Sollecito's kitchen? And why did Sollecito implicitly confirm it was Meredith's DNA?
The footprint found was excluded as being one of Guede's, because it was size 37 or 38 - not 42 (Guede's size).
An abundant amount of Raffaele Sollecito?s DNA was found on Meredith?s bra clasp, and Dr. Stefanoni excluded the possibility of any contamination.
Sollecito?s lawyer Ms Buongiorno is perhaps not surprisingly claiming that this bra clasp was also contaminated in the laboratory. The problem for them is to explain precisely where such an abundant amount of Sollecito?s DNA could have come from, and how it was so firmly imprinted. The only other instance of Sollecito?s DNA at the cottage was found on a cigarette butt in the kitchen, seemingly an unlikely source at best.
It would seem unlikely that the judges and jury will conclude that the bra clasp was contaminated in a strictly controlled laboratory where Dr. Stefanoni follows rigorous laboratory procedures. She is an internationally renowned and very experienced forensic expert and was part of a Disaster Investigations Team which identified disaster victims via their DNA.
The prosecution demonstrated on the final full day of testimony that Meredith?s bra was actually removed with a knife some time after she had been killed.
Who had a reason to come back, cut off Meredith?s bra, and move her body some time later? Judge Micheli concluded that it would only have been done by someone who knew about Meredith?s death and had an interest in arranging the scene in Meredith?s room to point away from themselves. He discounted Rudy Guede, who apparently went home, cleaned himself up, and then was seen out on the town.
There were five instances of Amanda Knox?s blood or DNA mixed with Meredith?s blood in three different locations in the cottage: in three places in the bathroom (on the ledge of the basin, on the bidet, and on a box of Q Tips cotton swabs), in the hallway, and in Filomena?s bedroom.
Dr. Stefanoni testified that it would have been ?strange? that three traces of blood with both Meredith?s and Amanda Knox?s DNA would have been left at different times.
There were no DNA or other physical traces of Rudy Guede in the "bloody" bathroom.
