(FILES)Amanda Knox waves to supporters as she makes

(FILES)Amanda Knox waves to supporters as she makes her first appearance at SeaTac Airport after arriving in Seattle following her release from prison in Italy in this October 4, 2011 file photo. Amanda Knox, a US student who spent four years in jail in Italy on charges of murdering her British roommate, Meredith Kercher before she was acquitted, is to give her first television interview, ABC news said February 11, 2013. "Now, after the dramatic Italian trial, conviction, and the court appeal that finally acquitted and freed her she will speak to ABC News," the network said, announcing that the interview will be broadcast on April 30. The interview comes just as Knox, who was a college junior at the time of the incident, launches a press tour promoting her memoir "Waiting to Be Heard," which will be published by HarperCollins on April 30. HarperCollins, a subsidiary of Rupert Murdoch's News Corp., did not reveal financial details, but The New York Times has said Knox sold the rights to her story for nearly $4 million.
