Amanda Knox will not return to Italy for a new appeals trial concerning the 2007 murder of her Meredith Kercher, her British roommate, the Associated Press reported. Knox received unfortunate news in March when Italy's supreme court ordered a retrial in a Florence appeals court, citing "numerous examples of shortcomings, contradictions and incoherences" with the original appeal ruling.

The court contended that the jury that acquitted Knox had not considered all the evidence, the AP reported.

In 2011, she was acquitted after overturning a conviction by a lower court. The new appeals trial is set to begin in Florence on September 30.

The 26-year-old Knox, now based at home in Seattle, served for years of a 26-year sentence in an Italian prison.

Rudy Guede, an Ivory Coast drifter, remains the only person in prison for Kercher's murder, and is serving a 16-year sentence after being tried separately and convicted of murder and sexual assault.

Prosecutors have contended that the murder could not have been carried out by a single person. Kercher's half-naked body was found in a pool of blood in the house she shared with Knox. Prosecutors have said the murder had been part of a sex game gone terribly awry.

Knox told CNN's Chris Cuomo that "I'm afraid to go back there. I don't want to go back to prison. I don't want them to, all of a sudden, do a court order just because I'm there... and the prosecution would ask the court that I'd be put in preventative detention again. I was there for 4 years."
