"Amanda Knox could not stick with an alibi. On November 2, she told officials she had spent the night at her boyfriends house. Four days later, she changed her story, saying she was at home and Kercher was having sex. At some point she stated she had observed Kerchers former supervisor [Patrick] in the home and he had committed the crime; on November 30 she recanted this statement. In December of 2007 she claimed as she slept, her boyfriend raced over to her home, killed Kercher, snuck back to his place, and put Knoxs fingerprints on the murder weapon as she slept.
Perhaps she does not understand, because of her youth, or arrogance, or both, anything she writes can be seized as evidence. But it has, and her diary contains excerpts such as, "I have received letters from fellow inmates and admirers telling me that I am hot and they want to have sex with me." She also writes of, smoking a lot of pot.
