The new appeal trial of Amanda Knox and her former boyfriend Raffaele Sollecito, whose Italian convictions for the 2007 murder of Meredith Kercher were overturned, began in Italy on Sept. 30, 2013. The country’s high court may hinge its final decision on their guilt on a piece of untested evidence found on the butcher knife officials argue killed Meredith, according to CBS News.
Knox, who returned to the United States after being released from prison, has publicly stated she will not return to Italy for the trial. Sollecito will be in the courtroom near the end of the trial, according to CBS.
The tiny piece of evidence, labeled “36-I,” is a small trace of material found on a 12-inch kitchen knife blade, which prosecutor’s argue was used to murder Meredith. It was found in the kitchen drawer of Sollecito’s apartment in Perugia.
In 2010, an appellate court called into question the initial DNA testing in the case and eventually reevaluated another piece of trace evidence labeled “36-B,” which was found to be unreliable, leading to Knox and Sollecito’s aquittals.
According to CBS, if 36-I contains Meredith’s DNA, Knox and Sollecito will be determined guilty in the murder. However, if Meredith’s DNA is not on the knife, the two will be considered not guilty of the crime once and for all.
