Amanda Knox has written a eight page letter to judge, saying that she is innocent and did not commit the murder.
In the letter she also wrote that she's not a thief or a plotter or an instigator, saying that she did not kill Meredith Kercher or take part in her murder or have any prior knowledge of what occurred that night, the Daily Star reported.
Knox said that she was not there and had nothing to do with it.
She and her former boyfriend Raffaele Sollecito, 29, were last week re-convicted of murdering 21-year-old Kercher in Perugia in 2007.
Knox, who faces extradition to Italy after being sentenced to 28 years in jail, said that that there was no physical evidence that placed her in Kercher's bedroom where the student was found with her throat slashed.
She also said that her interrogation by police was illegal, asserting that she was lied to, yelled at, threatened, and slapped twice on the back of the head.

Knox also wrote that she was coerced into signing a false confession that implicated Patrick Lumumba, who was later found to have a solid alibi.
She added that she never had any contact with Rudy Guede, 26, the jobless drifter who was sentenced to 16 years in jail for the murder.
