AMANDA Knox is preparing to fly home to the US after she and ex-boyfriend Raffaele Sollecito were cleared of the murder of Briton Meredith Kercher, BBC reports.
An Italian appeal court overturned their conviction for killing the 21-year-old Leeds University student, from south London, in Perugia in 2007.
Miss Knox, 24, and Mr Sollecito, 27, had spent nearly four years in jail.
Miss Kercher’s family said they did not understand how the original verdict could be so “radically overturned”.
However, the family – in Perugia for the decision – added in a statement: “We still trust the Italian justice system and hope that the truth will eventually emerge.”
They have previously spoken of their distress that Miss Kercher had been “nearly forgotten” in the publicity surrounding Miss Knox’s appeal and are expected to give a press conference later.
The prosecution is to appeal to Italy’s highest court, although it appears unlikely that Miss Knox would be extradited back to Italy from the US.
An eight-member jury cleared both defendants of Miss Kercher’s murder after doubts were raised over procedures used to gather DNA evidence.
The judge upheld Miss Knox’s conviction for slander for accusing bar owner Patrick Diya Lumumba of carrying out the killing. But he set the sentence at three years, time that Miss Knox has already served, meaning she was free to leave.
She was ordered to pay him 22,000 euros (£18,800) in compensation.
Her family said she had “suffered for four years for a crime she did not commit”.
Speaking on the steps of the court, Miss Knox’s sister Deanna said: “We are thankful to the court for having the courage to look for the truth and to overturn this conviction.”
She said Miss Knox’s “nightmare was over” and asked for privacy for her family to recover from “this horrible ordeal”.
Her lawyer, Carlo Della Vedova, said outside court that there was “no winner” in the case and the appeal court had “rectified a mistake”.
“Meredith was a friend of Amanda – we should never forget this and we have to respect the sorrow of all the families,” he told the BBC.
Mr Sollecito’s father Francesco said he had “allowed himself some tears” following the verdict and said the court had “given me back my son”.
Hundreds of people had gathered in the streets outside the court ahead of the verdict and some shouted “shame” when they heard about the decision, while others cheered.
During the appeal hearing Miss Knox, who was serving 26 years in jail for the killing, had told a packed courtroom: “I did not kill, I did not rape, I did not steal. I was not there.”
Tearful, and speaking in fluent Italian, she added: “I want to go back home. I want to go back to my life. I don’t want to be punished. I don’t want my life and my future to be taken away for something I didn’t do because I am innocent.”
Her ex-boyfriend Mr Sollecito, who had been given a 25-year term after the initial trial, told the court in his statement that he was in a “nightmare” and said the claims against him were “totally untrue”.
Miss Kercher had been sharing a cottage in Perugia with Miss Knox, who is originally from Seattle, during a year studying abroad when she was murdered.
Prosecutors said she was killed in a brutal sex game which went wrong. Her throat had been slit and she had been sexually assaulted.
They maintain that Miss Knox’s DNA was on the handle of a kitchen knife – found in Mr Sollecito’s flat and believed to be the murder weapon – with Miss Kercher’s DNA on the blade.
They also said Mr Sollecito’s DNA was on the clasp of Miss Kercher’s bra.
But an independent review disputed those findings, raising concerns over poor procedures in evidence collection and forensic testing, and possible contamination.
It put in doubt the attribution of the DNA traces – collected from the crime scene 46 days after the murder.
In a separate earlier trial, a third person – Rudy Guede, 24 – was convicted of Miss Kercher’s murder and was sentenced to 30 years in prison.
His conviction was upheld on appeal but his sentence reduced to 16 years.
