"I will never willingly go back" to Italy, Knox says

CNN  — 

Add one more uncertainty to the many questions that surround the Amanda Knox murder verdict: Will she wind up back in a cell in Italy?

“I will never go willingly back,” she told ABC’s “Good Morning America” on Friday. “I’m going to fight this until the very end, and it’s not right and it’s not fair and I’m going to do everything I can.”

Knox, who is American and living in the United States, said she watched the guilty verdict handed down Thursday by an Italian appeals court over the Internet, translating what was happening to family members who were with her. “This really has hit me like a train. I did not expect this to happen.”

“I really expected so much better from the Italian justice system,” she added. “They found me innocent before, how can they say it’s guilty beyond a reasonable doubt?”
