Transcript for The New Amanda Knox
Now picking up with Amanda's triumphant return to American soil and that fresh air of Seattle. She was free, for now. But the traumatic memories for Italy and her time in jail were never far away and nor was the wait of wondering if she could be sent back to serve a new sentence. With this week's verdict, those fears are now front and center. "I'm really overwhelmed right now. When Amanda Knox set foot on U.S. Soil for the first time following the reversal of her Italian murder conviction, she was fighting back tears. I was looking down from the airplane, and it seemed like everything wasn't real." As we spoke with her last year -- Knox was back with her family trying to resume a life interrupted by the murder of her college roommate. Thick prison walls, suddenly replaced by the lush green of Seattle. And the company of her sister, dean Deanna. After being surrounded by the concrete for years, the same dirtiness and gray and hardness, it was incredible to be surrounded by these huge trees and the softness of the ground. Wanting to slip back into the once quiet life she had there, Amanda enjoyed simple pleasures like playing video games. She was even able to talk about her life behind bars. Did I tell you about different ways that we learned how to remove hair in prison because we weren't allowed to have raiders -- Different way -- Like shave your legs? You can use rubber bands. But kidding aside those days in prison haunted her. I had panic attacks. There were times when I couldn't breathe. How do you deal with did when it was too much for even you. The body was free. The mind was not. The emotional psychological prison is worse than the physical one. My mom recommended once that I just go and talk to a therapist and see what they thought. And I was amazed that I completely broke down. I thought I was fine. I thought I was okay, I was home. And, and I wasn't. I was so angry and so sad. But that fragile coping process was disrupted last spring when she learned her ordeal was not over. When the Italian courts ordered another trial. I'm not ever going to accept the idea that anyone can say that I did something that I didn't. And with that tough news -- the paparazzi once more came out of the woodwork. Amanda, how are you doing? How are you coping Amanda? "How are you coping Amanda?" There was paparazzi lined up outside of the house, and Amanda, again, doesn't want to have anything to do with that. It's just weird and disturbing for her. Amanda has taken control of what she can, agreeing to that multi-million dollar book deal about her trial and prison time in Italy. But putting that pain on the page did not come easily. I was at times so angry and so sad, I just lad to step away. I had to get away from my computer, I had to get away from the memory, I had to go on my bed and cry, I had to go and walk around the block five, ten times to just breathe. Knox, who is scheduled to earn a degree in creative writing at the university of Washington this June, realizes her life is effectively "On hold. Meanwhile, she has offered her support for those wrongly convicted -- like Ryan Ferguson, recently exonerated for murder after ten years in prison and he is now a trusted friend. Having somebody else to talk to that has experienced the same circumstances, I think, you know, they can share their emotions with each other and how to try to deal with them. There was also the decision to cut her long brown her that helped define the foxy knoxy person persona. But the H but her primary focus remains on the one case she can't escape. There have been three verdicts rendered on Amanda Knox in the murder of Meredith Kercher. Two of them guilty, one of them innocent. Is it possible the jury that found her innocent is the one that's wrong? No country has a monopoly on justice. And this is not a question of nationality or location. This is simply a question of a wrongful conviction. Her family said they will fight this wrongful convection at every step, every stage, and every place they can possibly can. I expect that will happen. Needless to say the family's opinion of Italy changed since that first semester abroad. I wish it wasn't about saving face in Italy. I'm going to keep fighting this. I'm going to keep fighting this and I'm not going to stop fighting this. ♪
