"This is not a surprise," said another member of the Knox legal team Carlo Dalla Vedova. "For us, it's confirmation of what we have known all along, that the DNA results were not reliable, they were uncertain."
Dalla Vedova said the report's conclusion on the knife was that it was impossible to "relate the DNA said to be Meredith's to her with certainty" and that there is the possibility of contamination with knife too.
"We have asked all along for an independent review of DNA which we were denied during the trial. Finally, after three and a half years, independent experts confirmed that the DNA results were not reliable and they were inconclusive."
The 144 page report filed in court today will be discussed in court in Perugia on July 25.
A third person was also convicted of the murder. Ivory Coast drifter Rudy Guede is serving a 16 year prison sentence. Earlier this week, Guede appeared before the appeals court and prosecutors read a letter that Guede wrote to his lawyer in which he stated that Knox and Sollecito were present during the murder.
"I was hoping that Rudy would actually own up to his responsibility and essentially tell the court that Amanda and Raffaele had nothing to do with it," Curt Knox said. "It was very disappointing that he wouldn't fess up to that."
Guede was rebutting testimony from a former cellmate that he had confided to him that Knox and Sollecito were not present during Kercher's murder.
Knox's seemingly bizarre behavior after the murder has been cited by prosecutors. Police told the court in 2009 that she had a "strange attitude" after discovering her roommate had been killed and did a cartwheel in the police station, among other things.
"[The report] should glean a very shining light on that fact and while she may not have reacted the way people would expect, it really does not mean she's a murderer," her father said.
