ROME , Italy -LRB- CNN -RRB- -- 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 . Knox and Sollecito were both present at Monday 's court session , Kercher 's attorney Francesco Maresca said . Sollecito 's defense attorneys requested the annulment of DNA analysis , which investigators say shows Sollecito 's genetic material on the clasp of the victim 's bra . The judge rejected the request . The next hearing is scheduled on Friday , Maresca said . Knox , from Seattle , Washington , took the stand in June and testified that she was not at the girls ' villa the night her roommate died , which authorities think was the evening of November 1 . She said she was visiting her then-boyfriend , Sollecito , at his home , where the two watched a movie , smoked marijuana , had sex and went to bed . On her return to their villa the next morning , Knox said , she noticed `` strange things , '' such as the front door left open , dried blood in the bathroom sink and a locked door to Kercher 's room . When Knox returned to Sollecito 's house , he suggested they call police in case the house had been burgled , she said . Police found Kercher 's body in the house . Prosecutors say evidence places the defendants at the scene . They also said the suspects gave investigators confusing and contradictory statements about their whereabouts the night Kercher died . Knox said she gave conflicting answers at the interrogation on November 6 because of police pressure and her confused state . `` When I would say that I was with Raffaele , they would say , ` You are a liar , ' and they repeated this , '' she said in June , speaking about the police . '' ` You will go to prison for 30 years . ... You must remember . ' '' During the trial , she said police had slapped her on the head during questioning , a charge she had made before . The case has attracted worldwide media attention . During her testimony in June , cameras were barred from the courtroom because the prosecutor said he wanted to avoid sensationalism . A third person , Ivory Coast native Rudy Hermann Guede , was convicted of murder in the case in October and was sentenced to 30 years in prison . He is appealing his conviction .
