Perugia, Italy (CNN) -- Prosecutors fighting to keep American student Amanda Knox behind bars for murder in Italy defended on Monday the DNA tests that linked her to the killing of British student Meredith Kercher. Knox is appealing her conviction and 26-year sentence for the murder of her housemate in 2007, with her defense team arguing that DNA evidence used in her original trial is not conclusive. This summer two new forensic experts, professors Carla Vecchiotti and Stefano Conti, cast doubt on the DNA evidence that played a role in the convictions of Knox and ex-boyfriend Raffaele Sollecito. "I think the prosecution is trying to take the independent experts' testimony away and frankly, I don't see that happening," Knox's father, Curt, told reporters after court adjourned Monday. "I mean, I think the independent experts have done a very good job in evaluating the information ... and I don't see it breaking down at this point. I see that it has been good for Amanda."
