Meredith Kercher's family voiced disappointment on Tuesday and said the truth was still to be established after Amanda Knox and her ex-boyfriend Raffaele Sollecito were cleared of the murder.

We still don't have the answers," Kercher's sister Stephanie told reporters in the university town of Perugia, a day after the convictions against Knox and Sollecito were overturned by an appeals jury.
