ROME, Italy (CNN)  -- The murder trial of American student Amanda Knox in the death of her housemate two years ago resumed Monday in Italy after a summer break. The trial of American college student Amanda Knox, 22, resumes Monday, September 14. Knox, 22, and her Italian ex-boyfriend Raffaele Sollecito also face charges of sexual assault. They are accused of killing British student Meredith Kercher, Knox's housemate in Perugia, a scenic university town north of Rome. Kercher, 20, died in what prosecutors called a "drug-fueled sex game." She was found half-undressed in bed, with a stab wound to her neck on November 2, 2007.
