A prosecutor has urged an Italian court to take steps to make sure that Amanda Knox and Raffaele Sollecito would serve their sentences, if they are convicted of murdering British student Meredith Kercher.

An Italian prosecutor has demanded that an appeal court find Amanda Knox guilty of the 2007 murder of her British roommate, Meredith Kercher, a killing he argued may have been rooted in arguments about cleanliness and triggered by a toilet left unflushed by the only man now in jail for the murder.

An Italian appeals court has been urged to re-convict Amanda Knox for the murder of British student Meredith Kercher and undo the alleged mistakes of the hearing that freed her.
