Crime / Amanda Knox Knox Pulled Knife on Him, Witness Says Homeless man puts suspect, boyfriend near murder scene By Harry Kimball, Newser Staff Posted Mar 28, 2009 3:02 PM CDT Copied US murder suspect Amanda Knox smiles at her lawyer Luciano Ghirga during a hearing in the Meredith Kercher murder trial, in Perugia, Italy, Friday, March 27, 2009. (AP Photo/Stefano Medici) A witness in the Amanda Knox murder trial testified that she waved a knife at him outside the house where Meredith Kercher was killed, the AP reports. The Albanian witness, at times mumbling and interrupted by the judge, said he “bumped into a big black trash bag” that turned out to be Knox and boyfriend Raffaele Sollecito. The witness said he “threw olives and a cell phone” at Knox when she brandished the knife. Knox’s attorney called the Albanian’s testimony “unreliable," but prosecutors said it was key. In other testimony at the Italian trial, a homeless man said he saw the couple together “chatting, at times animatedly,” on a basketball court near the scene of the crime on the night Kercher was killed. Knox claims she was at Sollecito's house at the time. (More Amanda Knox stories.) Report an error
