Is Amanda Knox headed for another acquittal? DNA tests 'show no traces of victim's blood on kitchen knife touted by prosecutors as the murder weapon' Forensic experts found Amanda Knox's skin cells on knife seized from Rafaele Sollecito's apartment that she'd used for cooking Tests showed no traces of victim Meredith Kercher's DNA on the knife Knox's retrial began in Florence last month but she is in Seattle Miss Knox and her one-time lover Sollecito have already served four years in jail following the murder of Meredith Kercher By Hugo Gye and Snejana Farberov American student Amanda Knox, who is facing a retrial in Italy in the murder of her roommate, received some good news this week when forensic experts revealed that there were no traces of the victim's DNA on the alleged murder weapon. On Friday, experts began tests on a kitchen knife that the Italian prosecutors claimed was used to murder British student Meredith Kercher in Perugia in 2007. Two years ago, Knox and her former boyfriend, Raffaele Sollecito, were cleared of all charges in connection to Kercher's murder after they had served four years in prison for the crime. Amanda Knox, 26, could be heading for another acquittal in Italy after forensic experts have failed to find any trace of Meredith Kercher's DNA on a knife that was alleged to be the murder weapon Perugia police seized this large kitchen knife from her lover Raffaele Sollecito's apartment, where Knox allegedly had used it for cooking In March, Italy's highest court ordered the new trial for the pair, overturning their acquittals. The 26-year-old Knox, who has been attending college in Seattle since her return to the U.S., announced that she will not go to Italy to face another trial. This latest revelation that skin cells found on the knife are not those of Kercher could refute the prosecution's claim that Knox used the large piece of cutlery to kill the British national. Following Kercher's slaying in 2007, Perugia police seized the sizable kitchen knife from Sollecito's apartment, where Knox allegedly had used it for cooking, according to the Seattle Post-Intelligencer. DNA testing performed this week have shown that skin cells found between the handle and the blade are those of Knox, not Kercher. The fact that Kercher's blood was not found on the blade could possibly spell a second acquittal for Knox when the retrial comes to a close November 26. Knox's attorney Ted Simon told ABC News Friday that he was satisfied with this turn of events in Italy. Amanda Knox was all smiles in the rain in Seattle, Washington, last month as she chatted on the phone while picking up supplies at a pet store ahead of the re-trial in Italy Meanwhile, Sollecito's attorney, Luca Maori, said that all evidence points to the fact that contrary to the prosecutors" version of events, the knife that has become the centerpiece of the case against his client and Knox was not the murder weapon after all. The forensic experts will officially unveil the results of the DNA tests during a court hearing November 6. The appellate court hearing the new case could declare Knox's in contempt of court for failing to return to Italy for the trial, but that carries no additional penalties.
