A woman believed to be Amanda Knox, center, is escorted from her mother's home to a car by family members.

SEATTLE — Though more than 5,000 miles from the Italian court, Amanda Knox said she was “frightened and saddened” when the judges reinstated a guilty verdict against her and an ex-boyfriend in the 2007 slaying of a British roommate.

Knox had remained in Seattle during the trial. David Marriott, a family spokesman, said Knox awaited the ruling Thursday at her mother's home. After the decision was announced, a person believed to be Knox emerged from the house. That person, surrounded by others and covered by a coat, got into a vehicle and was driven away.

When asked how Knox was doing, her mother, Edda Mellas, said: “She's upset. How would you be?”

Knox said in a written statement that she was “frightened and saddened,” she “expected better from the Italian justice system,” and “this has gotten out of hand.”

The University of Washington student was sentenced to 28½ years in prison, raising the specter of a long legal battle over her extradition.

Knox, 26, said she and her family “have suffered greatly from this wrongful persecution.”
