Italian police have found DNA traces of a slain British student and of her American roommate -- jailed as a suspect in the case -- on a knife that may have been the murder weapon, lawyers said. Police seized the kitchen knife in the house of Raffaele Sollecito, 24, the Italian boyfriend of American Amanda Marie Knox. Both have been arrested, along with Congolese musician and bar owner Diya "Patrick" Lumumba, 38, on suspicion of killing 21-year-old Meredith Kercher.Sollecito's lawyers and family said in a written statement Thursday evening that traces of the DNA of both Knox and Kercher were found on the knife in Sollecito's house. Sollecito's DNA was not found on the knife, the statement said.
Italian newspaper Corriere della Sera said that Kercher's DNA was found on the tip of the knife, while Knox's was on the handle. Corriere della Sera and other reports said the knife had a 6.7-inch blade, and that investigators believed it to be the murder weapon.
Knox's lawyer was not available for comment Friday.
