Coroner challenges DNA evidence in Kercher murder trial

News agencies are reporting that a coroner has challenged DNA evidence linking an Italian to the 2007 killing of a British student in the central Italian town of Perugia.

The ANSA news agency said Dr Adriano Tagliabracci, a defence witness, testified today in the trial of American Amanda Knox and her Italian former boyfriend, Raffaele Sollecito, for the murder of Meredith Kercher. Both deny wrongdoing.
