Amanda Knox

Amanda Knox, whose murder conviction was overturned in 2011, will not travel to Italy for a new trial in the death of fellow student Meredith Kercher. A spokesman for the Knox family tells CNN that Knox's presence isn't required at next month's trial.

Less than two months into her study abroad program in Italy, Amanda Knox was accused and eventually convicted of murdering her roommate, Meredith Kercher. After her conviction was overturned, Knox returned home to Seattle — and now faces a potential retrial. Knox tells her story in a new memoir.

In a surprise ruling, Italy's highest court ordered a retrial of American student Amanda Knox and her former boyfriend for the murder of British student Meredith Kercher. The ruling overturned the 2011 acquittal of the two defendants after they had spent four years in jail.

The young American was convicted in the brutal 2007 murder of an English exchange student. Later, an appeals court overturned that verdict. But now, Italy's highest court has ordered a retrial. Knox is in the U.S. If she is convicted again, Italy might seek her extradition.

Amanda Knox, the U.S. college exchange student who won an appeal to overturn her murder conviction in Italy last October, has signed a deal to write a memoir — for which she'll earn nearly $4 million, according to reports.

Meredith Kercher's brother says her family feels as if it's now "back to square one." Knox is expected to be home in Seattle later today.

An Italian panel has granted Amanda Knox's appeal of her murder conviction, for which the American had been serving a 26-year prison sentence. Knox, who came to Perugia, Italy, as an exchange student, had been found guilty in the November 2007 murder of British student Meredith Kercher.
