Knox appeal trial allows new DNA test on knife

Amanda Knox’s second appeal trial has agreed to additional DNA tests on the weapon presumed to have murdered her British housemate Meredith Kercher.

The Italian judge has agreed to test one DNA trace not previously examined because it had been deemed too small. A court-ordered review in the first appeal trial discredited DNA evidence on the kitchen knife linked to Ms Kercher.

Italy’s highest court in March ordered the new trial for American student Knox and her former Italian boyfriend, Raffaele Sollecito, overturning their acquittals in Ms Kercher’s 2007 murder.
