Amanda Knox: Fearful of returning to Italy, says 'There's no evidence against me'

(CNN) -- Amanda Knox says she's scared to return to Italy to face a new trial nearly six years after her study-abroad roommate's slaying. But she's considering it.

"In Italy," she told CNN's Chris Cuomo, "people think it's arrogant of me to sit here in the United States and have a book come out and to defend myself."

"First of all, I find that incredibly unfair because I have the right to defend myself. And no one can ask me to just shut up because it's convenient," she said. "But at the same time, I want to prove to them that I care about what's going on."

For years, the twists and turns of the case against Knox have drawn international attention.

Knox and boyfriend Raffaele Sollecito were convicted in the 2007 rape and slashing death of 21-year-old Meredith Kercher at Knox and Kercher's apartment in Perugia, Italy. A jury overturned the conviction in 2011, and Knox flew home to Seattle.
