By Daily Mail Reporter PUBLISHED: 10:11 EST, 25 September 2013 | UPDATED: 11:16 EST, 25 September 2013 The evidence that sealed the convictions of Amanda Knox and Raffaele Sollecito for the murder of British student Meredith Kercher is far from conclusive, a new investigation claims. On the eve of the retrial of the former lovers in Florence, a documentary has asked five key questions about the case against them. Miss Kercher, 21, a European Studies student from south London, had her throat slashed on November 1, 2007, at her apartment in Perugia, Italy. She shared the flat with Knox, from Seattle, Washington.
