Amanda Knox retrial extradition won’t happen unless she is found guilty. Lawyers said Amanda Knox will not return to Italy for the new appeals trial in the 2007 killing of her roommate., Meredith Kercher.

Amanda Knox's attorney Luciano Ghirga told La Nazione that after meeting with Amanda Knox and her legal team that the former Seattle college student said she will not go back to Italy for the new trial. The Amanda Knox murder trial is scheduled to start on Sept. 30 in Florence, Italy.

Amanda Knox, 25, was convicted of the murder of her British roommate, Meredith Kercher in Perugia, Italy. Amanda Knox spent four years in prison before the conviction was thrown out by an Italian appeals court in 2011. The Italian Supreme Court rejected the Appeals Court ruling in March. Amanda Knox and her ex-boyfriend Raffaele Sollecito, 29, have been ordered a sit for a new trial. The Supreme Court filed its papers on June 18 that said the Supreme Court judges supported the prosecutors' original theory. Prosecutors claimed that Amanda Knox and Sollecito caused Kercher’s death during a forced "erotic game" that turned violent. The Supreme Court judges ruled on the Appeals Court process, not the testimony or evidence in the case.

The Supreme Court judges said the appeal should be annulled "due to the multiple shortcomings, contradictory events and manifest lack of logical reasoning."

The sex game theory evolved into a growing enmity between the roommates because Kercher accused Amanda Knox of stealing money and bringing home boys late at night. The prosecution told the jury that people sometimes commit violence without a motive.

The court documents show that the judges looked at a "wide range of possible hypothetical options" that included "the change in a program which at first only included the involvement of the English young woman in a sex game which she didn't share, to exclusively forcing her into a group kinky erotic game, which exploded, getting out of control."

When the ruling was announced Carlo Dalla Vedova, Amanda Knox's lawyer, said he disagreed. He told ABC news, "We respect the Supreme Court's decision, but we do not agree with it. All the facts were analyzed already. So now we simply re-start and re-do the case. We are ready to start again in Florence, and we are looking forward to defending Amanda. She is completely innocent."

Amanda Knox told Diane Sawyer on an April ABC News special that the third trial ordered by the Supreme Court was "incredibly painful." She said "I felt like after crawling through a field of barbed wire and finally reaching what I thought was the end, it just turned out that it was the horizon. And I had another field of barbed wire that I had ahead of me to crawl through."

Amanda Knox will not be extradited back to Italy. If she is convicted again, her case will go back for an appeal in the Italian Supreme Court. Extradition would only begin if the Supreme Court upholds the guilty verdict.
