PERUGIA, Italy -- Amanda Knox sought comfort from visiting family members Saturday on her first day in prison since being convicted of murdering her British roommate.

The family of victim Meredith Kercher said the verdict brought a measure of justice. However, they said, it was not a time to celebrate.

Knox, a college student from Seattle, was tired and upset following the midnight verdict and sentence of 26 years in prison, according to family members and a lawyer who saw her.

"Amanda like the rest is extremely disappointed, upset about the decision," Knox's mother, Edda Mellas, said after the visit to the prison just outside Perugia. "We told her that she's gonna get out of here. It's gonna take a little longer."

Knox and Kercher's families came to this central Italian town for the verdict, which was announced at around midnight after 13 hours of deliberations. The court also convicted Knox's co-defendant and former boyfriend, Italian Raffaele Sollecito, and gave him a 25-year jail term for the murder.

Knox and Sollecito are appealing the verdicts.

"She couldn't sleep all night," said lawyer Luciano Ghirga, who spent an hour with Knox at her jail just outside Perugia on Saturday morning. "She's worried for her parents, too, but she is keeping the faith needed for the next steps."

Ghirga said Knox was kept under strict surveillance. He denied reports that she had been put under suicide watch, which is the standard practice in such cases.

Kercher, 21, was Knox's roommate while they studied in Perugia.

Her body was found in a pool of blood with her throat slit on Nov. 2, 2007, at the apartment they shared. Prosecutors said the Leeds University student was murdered the previous night.
