After all previous murder convictions against Amanda Knox and her ex-boyfriend Raffaele Sollecito were overturned by Italy's highest court, the former American exchange student now fears for her life. According to The Sun, Knox's camp has asked the FBI for help after she reportedly received a number of death threats from someone they know.  

"We've been given reason to believe they have the ability to carry out their threats," said a source close to the family. "We know who it is and their address. The FBI is investigating. The vast majority of internet trolls harassing Amanda are British." 

The decision of Italy's highest court to overturn the murder conviction against Knox and Sollecito ended the high-profile case that has been followed all over the world, particularly in the U.S. and Europe. It began when Knox's British roommate Meredith Kercher was brutally murdered in their four-bedroom apartment at Via della Pergola 7 in Perugia, Italy. Both Knox and Sollecito were found guilty by the Corte d'Assise back in 2009 of committing sexual assault, murder, and simulating a burglary. Knox was given a 26-year sentence, while Sollecito got 25 years. 

Knox's legal team filed an appeal in 2011 at the Corte d'Assise d'Appello, which said that both she and her former boyfriend are not guilty. However, a retrial was filed on March 2013 at the Supreme Court of Cassation, which is the highest court in Italy. Again, the two were found guilty when the verdict was read on January 2014. 

But the Supreme Court of Cassation overturned all guilty verdicts on March 27 this year, saying that there are no substantial evidences tying both Knox and Sollecito to the crime scene.
