What the Past 2 Years Have Done to Amanda Knox

The Amanda Knox of 2011 bears little resemblance to the confident-bordering-on-cocky Amanda Knox of 2009. In a look at how the last two years have changed the American, the AP talks to her family and friends, and paints a picture of a more mature but more wary and anxious 24-year-old. Gone is the Beatles T-shirt, replaced by conservative satin blouses hung on a thinner frame. During the first trial, she smiled frequently; now she looks down, and has taken to clasping her hands in front of her face, as if in prayer. Critics argue it's all an act, one that's a result of careful coaching.

A friend says her days are spent reading, studying German, and working with fellow inmates. They're also spent working on a statement she plans to give the appeals court on Monday. Her father told the Today show that Amanda has spent three months working on it. "It's going to be truly heartfelt," says Curt Knox. "You've got a 24-year-old kid that's essentially fighting for her life and this is her last chance to actually tell the judge and jury that she truly had nothing to do with this horrific crime."
