*WARNING: THE CONTENT OF THIS STORY AND THE CRIME ARE GRAPHIC AND DISTURBING* Student's sex party that ended in murder http://www.telegraph.co.uk/news/main.jhtml;jsessionid=HAOWUADE0E1PRQFIQMGCFFWAVCBQUIV0?xml=/news/2007/11/08/wkercher108.xml By Malcolm Moore in Perugia, Nick Allen and Richard Alleyne Last Updated: 3:20am GMT 09/11/2007 The American girl accused of murdering the British student Meredith Kercher, who allegedly died in a violent orgy, made a tearful confession saying they just wanted to "have some fun," it has emerged. Extracts from Knox's police interview Amanda Knox admitted hearing Meredith Kercher screaming but did nothing to help her Amanda Knox, 20, broke down in her police cell as she told Italian detectives that she invited Miss Kercher to join an impromptu drunken party in the house they shared in Perugia. Knox, a student, said she and her Italian boyfriend Raffaele Sollecito, 23, ended up in one bedroom while Miss Kercher and a Congolese bar owner, Patrick Diya Lumumba, 37, went into another. "We were drunk and we wanted to have some fun, we invited Meredith to join us," Knox said. She admitted hearing Miss Kercher screaming but stuck her fingers in her ears and did nothing to help her. "I can't remember how long they were in there together," Knox said, according to extracts of the interview published in an Italian newspaper. "I can only say that at one point, I heard Meredith scream and I was frightened so I blocked my ears. I don't remember anything after that. My head's all confused. The incident has left me very disturbed and I am very afraid of Patrick." Today Lumumba, Knox and Sollecito are expected to be charged with murder and "participation in an act of sexual violence". Police believe Miss Kercher's throat was cut after she refused to have sex with one of the men. Italian media said that a pathologist's report suggested one person held Miss Kercher down while a second "sexually violated" her. Knox, a teacher's daughter, reportedly burst into tears when it was suggested she held her flatmate down. Police said that a footprint found in a pool of blood in the bedroom was "compatible" with Sollecito. Forensic scientists are also examining a three-inch flick knife found at his house. Knox originally told police that she and Sollecito spent the night at his house and returned the next day to find Miss Kercher's body. Detectives say they broke a window and ransacked the flat to give the impression she was killed by a burglar. The police bugged Knox's mobile phone and she was overheard telling Sollecito on Monday night: "I cannot do it any more, I cannot bear it." Orders were issued for a series of dawn raids on Tuesday and Knox broke down under interrogation. She burst into tears and made her confession at 5.45am after the interrogator said: "You did it, you held her down." Meredith's parents, John and Arline Kercher, and sister Stephanie [centre] pay tribute in Perugia Records showing the location of the phone also helped disprove her claim to have been elsewhere at the time of the murder. The police chief, Arturo De Felice, said Knox had "crumbled and confessed" under intense questioning. "There were holes in her alibi and her mobile phone records were crucial," he said. Police also found text messages from Lumumba, fixing a meeting between them at 8.35pm on November 1, the night Miss Kercher died. After admitting her alibi was false Knox told police: "We met at around 9pm at a basketball match in Piazza Grimana and we went to my house. "I don't remember if my friend Meredith was already at home or if she came in later. What I can say is that they went off together." Knox, who is on an exchange from the University of Washington, claimed she had played a "marginal role" in the crime. The Italian news agency Ansa said last night that it had seen court documents claiming she "has shown a tendency to lie repeatedly to investigators, implicating the young Sollecito in such a serious affair". One story on her MySpace internet page includes two brothers discussing drugging and raping a girl. She also posted a photograph of herself laughing as she plays with a machine gun. Sollecito, the son of a wealthy doctor, has apparently admitted telling police a "sack of lies" but denied any involvement in the killing. Miss Kercher, a Leeds University student from Coulsdon, Surrey, was on an exchange in Perugia.
