American student Amanda Knox, cleared last week of the 2007 murder of her roommate, British exchange student Meredith Kercher, is finally getting back on track.

Knox, 24, who is back in Seattle, Wash., ventured out for a shopping trip to grab a bar of chocolate and toothpaste, probably for the first time in four years, putting the four years of Italian prison ordeal behind her.

Knox's first attempt to get over her secluded existence comes along with new details of sexual harassment that she was subjected to while in prison in Perugia.

Knox Was Tricked into Believing She Had HIV to Extract Lovers List

Knox's younger sister Deanna told ABC News that she saw the remnants of the harassment firsthand while visiting her sister in prison.

There was something right in front of me and so I put my arm over it, Deanna Knox said.

Deanna Knox said she covered up scribbled words that read Amanda is a whore.

Soon after her arrest, the jail officials tricked Amanda into believing that she was HIV positive and coerced her into providing a full list of all the lovers she had slept with.

Please oh please, distraught Amanda wrote in her prison diary at the time. Let it not be true. I don't want to die.

The lovers list was leaked to Italian tabloids which made it to the headlines.

Harassed by Guards and High Ranking Jail Officials

On one occasion, a male guard allegedly entered Knox's cell alone, despite a policy against it, and made sexual remarks, ABC News reported.

Earlier, Knox alleged that she was sexually harassed by a high-ranking male prison administrator, who ordered her into his cabin at night to discuss sex.

We learn about sexual harassment inside prison where an administrator would take her up to his office alone at night and say a number of inappropriate things to her, and that left Amanda terrified, a CBS correspondent who interviewed Knox reported on The Early Show.

The official was stuck on the topic of sex, with whom I'd done it, how I liked it, if I would like to do it with him, said Knox, in a letter about sexual harassment in prison.

But when I realized that the official is obsessed with me to talk about sex I tried changing the topic several times, Knox added, I realize that he was just testing me to see my reaction and to understand me personally. He wanted to get some information from me regarding the case, but I did not get the seriousness of the situation.

Fighting Off Lesbian Inmates

Knox was reportedly approached by several women during her incarceration, who developed a special liking for her, according to a report by the Daily Star, which quoted a friend of Knox.

Someone came on to her and took a liking to Amanda, the friend, unnamed on request, said. Amanda isn't interested in that. She is not into girls.

Dislike to Anything Reminiscent of Italy

Amanda has reportedly developed a dislike for pasta, which was regular on the prison menu.

She is sick of pasta, put it that way. There was a lot of it in prison, her friend was quoted in the Daily Star.

Knox could sue the Italian court if she wanted, but it will require her returning to Italy, ABC News legal analyst Dan Abrams said.
