Italian investigators who collected the genetic evidence used to convict Amanda Knox of the murder of British student Meredith Kercher made glaring errors, including using a dirty glove and not wearing caps, independent forensic experts have said.
The two experts were appointed by an Italian appeals court to review evidence used in Knox's trial, including DNA found on a kitchen knife believed to be the murder weapon and on the victim's bra.
That evidence played a crucial role in convicting Knox (24), an American student, and co-defendant Raffaele Sollecito (27), in the 2007 murder of Ms Kercher, with whom Knox shared an apartment in the city of Perugia.
Knox and Sollecito have denied the killing. The evidence review was granted at the request of their defence teams.
