Crime | Amanda Knox Prosecutors Unveil DNA Evidence Against Knox American student's DNA found on weapon allegedly used to kill British student in Italy By Rob Quinn Posted May 23, 2009 3:17 AM CDT Copied Amanda Knox, right, is escorted by penitentiary police officers as she arrives for a hearing in the Meredith Kercher murder trial, in Perugia, Italy yesterday. (AP Photo/Stefano Medici) Italian prosecutors began presenting forensic evidence in Amanda Knox's murder trial yesterday, the Seattle Post-Intelligencer reports. Experts testified that the American's DNA was identified on the knife allegedly used to kill British student Meredith Kercher—who was found with her throat cut in the flat the two shared—and that DNA from Knox's co-defendant ex-boyfriend was found on Kercher's bra clasp. The evidence focused on mixed genetic traces from Knox and Kercher found in the apartment. Knox's lawyers said this was normal since the two lived together, although bloodstains containing DNA from both women were found in several places in the bathroom. The trial is now in its fifth month, and Knox is expected to take the stand after the prosecution finishes its case early next month. Read These Next A former NFL Pro Bowler has died at age 36.
