New York (CNN) -- If she had been at the scene of the crime, forensic evidence would prove her guilt, but Amanda Knox says there is nothing -- no DNA, no hair, no footprints, no handprints -- to show she was there. Knox spoke in an exclusive interview with CNN on Thursday, two days after an Italian court released an explanation of her conviction. In a retrial, Knox and Raffaele Sollecito, her then-boyfriend, were found guilty in the 2007 death of Meredith Kercher, Knox's onetime roommate. "I did not kill my friend. I did not wield a knife. I had no reason to," Knox said.
