Amanda Knox told CNN Thursday that she "never fought" with Meredith Kercher before the young woman's slaying.
"In the month that we were living together, we were becoming friends. A week before the murder occurred, we went out to a classical music concert together... we had never fought," Knox told CNN.
Knox's interview follows the Tuesday release of a 337-page conviction explanation document by the Italian court that reconvicted Knox and her former Italian boyfriend, Raffaele Sollecito, in the 2007 murder of Knox's 21-year-old British roommate.
Presiding Judge Alessandro Nencini concluded in the document that the evidence "inevitably leads to the upholding of the criminal responsibility" against Knox and Sollecito for the murder of Kercher.
Concerning motive, Nencini said relations between Knox and Kercher were strained for a number of reasons, including the alleged theft of money from Kercher's room -- a supposed crime none of the defendants were ever convicted of.
"I did not kill my friend," Knox told CNN. "I did not wield a knife. I had no reason to. If I were there, I would have traces of Meredith's broken body on me. And I would have left traces of myself around -- around Meredith's corpse... I am not there. And that proves my innocence."
Knox and Sollecito were first convicted of killing Kercher in 2009, but in 2011 those verdicts were overturned by the Italian Supreme Court at a second-level trial.
However, in Italy, a defendant who has been acquitted can be re-tried. Prosecutors appealed, and the Italian Supreme Court ultimately set aside the judgment of the appellate court in March 2013, granting another trial.
In January, the Florence court again found Knox and Sollecito guilty in the death of Meredith Kercher. Knox, who was not in Italy for the four-month trial, was sentenced in absentia to 28 1/2 years in prison. Sollecito's sentence was 25 years.
Knox has one last appeal pending before Italy's highest court. If she loses, Italy could ask U.S. authorities to extradite her.
"I truly believe that it is possible to win this, and to bring an end to all of the speculation and the nonsensical theories, and really bring peace to everyone who has suffered," Knox told CNN.
Sollecito appeared briefly on the Today show Friday to address the Italian court's newly released documents.
"They invented real fiction inside their report... It is out of reality," he said.
