Amanda Knox’s defence lawyer urged Italy’s highest court today to overturn the American’s conviction in the 2007 murder of her British roommate, calling it a “grave judicial error”.

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.

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 acquittal of accused murderer Amanda Knox was full of “deficiencies, contradictions and illogical” conclusions Italy’s high court has ruled, ordering a fresh look at all the evidence to determine whether she did kill her flatmate Meredith Kercher.
