Amanda Knox to Speak to ABC's Diane Sawyer in Exclusive Interview

Amanda Knox, the college junior who was at the center of a murder trial that riveted the attention of millions around the world, has never told her story. Now, after the dramatic Italian trial, conviction and the court appeal that finally acquitted and freed her, she will speak to ABC News.

The exclusive interview will air during a primetime special on TUESDAY, APRIL 30 at 10:00 p.m., ET on the ABC Television Network. It will also be featured across all ABC News broadcasts and platforms, including "World News with Diane Sawyer," "Good Morning America" and "Nightline," as well as ABCNews.com, Yahoo!, ABC News Radio and ABC's local affiliates.

Knox was convicted in December 2009 and spent four years in prison on the charge of murdering her British roommate, but was then released and cleared in October 2011. Her first-hand account of her journey from being an American student studying abroad to a woman facing decades in a foreign prison will include details she has never shared.

The interview airs in conjunction with the publication of Knox's highly anticipated book, "Waiting to Be Heard," which will be published by HarperCollins on April 30, 2013.
