(NewsNation) — Curt Knox, Amanda’s father, says he and his family are “very disappointed” with his daughter’s slander reconviction.

Amanda Knox was reconvicted in an Italian courtroom Wednesday even after she was exonerated in the 2007 killing of her British roommate while the two were exchange students in Italy.

The court found she wrongfully accused an innocent man of the killing. She will not serve any more jail time given a three-year sentence counts as time already served.

“The objective was to try to get Amanda’s name cleared of everything,” Curt Knox said Wednesday afternoon during an appearance on “Elizabeth Vargas Reports.” “The next step is going to be the appeals process to their Supreme Court.”

The slaying of 21-year-old Meredith Kercher in the idyllic hilltop town of Perugia fueled global headlines as suspicion fell on Knox, a 20-year-old exchange student from Seattle, and her new Italian boyfriend of just a week, Raffaele Sollecito.

At her first slander trial, Amanda Knox said police pressure had caused her to accuse an innocent man. The European Court of Human Rights ruled that the conditions of Knox’s interrogation violated her human rights.

Because of this, Italy’s highest court threw out the slander conviction, ruled the two police statements were not admissible and ordered a new trial. This time, the court was only able to examine Knox’s handwritten statements for elements to support slander.

Curt Knox said that because his daughter was only 20 years old and didn’t know the language, “she was brought up to try to help the police,” and “to have them turn on her was very unfortunate.”

“At this stage of the game, we have to look forward and keep the light on that she can be cleared of everything,” Curt Knox said. “(Amanda) tried to take what has happened to her to educate people on how to deal with situations and try to take something positive out of this.”
