(CNN) - The family of American student Amanda Knox is happy that new DNA analysis has called into question her murder conviction, but won't celebrate "until she walks out of that prison," her mother said Thursday.
In an interview with CNN's "Newsroom," Edda Mellas said her daughter is "not taking anything for granted." But a priest who was visiting Knox reported the results were met with "jumping and hugging" on Wednesday.
"There are many people that support her," Mellas said. "He said he could finally see the light back in her eyes, and she looked like she could finally breathe after three and a half years."
Knox and her ex-boyfriend, Raffaele Sollecito, were found guilty in the 2007 killing of Knox's roommate, Meredith Kercher. Kercher was found dead in the villa she rented with Knox in the central Italian university town of Perugia, semi-naked and with her throat slashed.
In December, Knox was sentenced to 26 years in prison. But Wednesday, forensic experts told an Italian court that the DNA evidence police used to link Knox to the murder weapon may have been tainted.
The next hearing in her appeal is scheduled for July 25, with further hearings on July 30 and August 1. Mellas said a decision on the appeal could come in late September.FULL STORY
