The United States will have little legal argument for turning down an extradition request should Italy seek the return of Amanda Knox for the 2007 murder of her British housemate.
In the latest dramatic twist in the high-profile case, a court in Florence on Thursday sentenced Knox to 28 years and six months in prison for killing Meredith Kercher in the university town of Perugia.
Knox was following the proceedings from her hometown of Seattle in the United States, where she has lived since a previous acquittal in 2011, which Italian prosecutors appealed.
Her lawyers now plan to appeal this latest conviction in turn to the Italian Supreme Court, but if they fail Knox could find herself flying back to a country where she has already spent four years in jail.
"As popular as she is here and as pretty as she is here -- because that's what this is all about, if she was not an attractive woman we wouldn't have the group love-in -- she will be extradited if it's upheld," said Harvard law professor Alan Dershowitz.
While Knox has won a great deal of support in the United States where she is seen as the innocent victim of a miscarriage of justice, Dershowitz said there are no legal grounds for preventing extradition.
