PERUGIA, Italy — Italian lawyers described Amanda Knox, the former University of Washington student convicted of killing her British roommate, as a “she-devil” and a “witch” in an appeals court Monday.

Knox and her former boyfriend were convicted of sexually assaulting and murdering Meredith Kercher. Seattle resident Knox, 24, was sentenced to 26 years. She has appealed her conviction, issued by a lower court in 2009.

Attorney Carlo Pacelli represents Diya “Patrick” Lumumba, owner of a Perugia bar who, after the 2007 murder, was unjustly accused by Knox of being the killer. He was briefly jailed and then cleared. Lumumba is a civil plaintiff in the case; in Italy civil portions of cases are heard at the same time as criminal content.

Pacelli maintained Knox has a double soul.

“Both a (saint) and a demonic, satanic, diabolical she-devil, which leads her toward borderline behavior. This was the Amanda of Nov. 1, 2007,” the night of Kercher’s slaying, Pacelli said.

“… She is a spell-casting witch, a virtuoso of deceit.”

Knox maintains police pressure led her to accuse Lumumba.
