Convicted killer Amanda Knox is pinning her hopes for freedom on two DNA experts. Knox was found guilty of murdering her roommate in 2007 while studying as an exchange student in Italy.
Amanda Knox smiled at her family as she returned to an Italian courtroom to fight her murder conviction.
The Seattle native is hoping an explosive new DNA report could set her free.
Mother of Amanda Knox, Edda Mellas, said, “I think she's feeling more hopeful. She feels like she can breathe. That's what she described to us. She feels like the chokehold is off her.”
24 year old Knox is serving 26 years for the brutal murder of British student Meredith Kercher.
Now court appointed DNA experts are picking apart police evidence used to help convict her, and her former boyfriend Rafaelle Sollecito.
At an appeal hearing Monday - the forensic scientists called the alleged murder weapon into question.
They told a judge and jury there is no proof Kercher's blood was on the knife Knox had touched.
Some experts say that alone could be enough to overturn Knox's conviction, “You throw out that evidence, the case is gone. She'll be coming home.”
Italian experts accused police scientists of a sloppy investigation full of glaring errors.
Prosecutors originally argued Kercher's bra clasp had Sollecito's DNA on it - which proved he and Knox were both at the killing.
But the new forensic report shows the clasp was left at the crime scene for six weeks - before police collected it using dirty gloves.
Italian police are accused of making more than 50 procedural slip-ups (or operational blunders) since the murder investigation began.
A final decision on Knox' appeal is expected at the end of September.
