Amanda Knox dad: No talk about prison yet

Amanda Knox comes homeAmanda Knox's father, Curt Knox, said on "The Early Show on Saturday Morning," that his daughter hasn't spoken with his family about her four years in an Italian prison since she returned to the U.S. this week.

However, in a letter CBS News obtained, Amanda Knox has claimed that she was sexually harassed by a high-ranking Italian prison administrator.

Amanda Knox returned to Seattle this week after her conviction in the murder of her British roommate Meredith Kercher in 2007 was overturned.

Amanda Knox: I was sexually harassed in prison

Curt Knox said, "When she has been home, we haven't really talked about, you know, what happened, and we really are looking forward, and, you know, so those types of conversations haven't taken place, but I'm sure they will over time."

Amanda is beginning her first weekend at home with her family in four years.

Curt Knox said after years with a short 10-minute Saturday conversation with his daughter in prison, he's looking forward to actually spending time with her in person.

"It's going to be so nice to actually be with her when that phone call would normally take place, so that makes a really big difference, and we are really looking forward to it," he said. "It's kind of a little bit of a milestone."

For Amanda Knox, freedom comes at a hefty cost

As for Amanda Knox and her family, she "hasn't missed a step," according to her father.

He said, "You know, when she left, she has some twin cousins that were 1-year-old and now they are 5, and to watch them play together, it is as if she was never gone and that is great to see."

"48 Hours Mystery" correspondent Peter Van Sant, who has covered the case since it began in Italy four years ago, reported Knox's family is keeping her whereabouts a secret.

Tom Wright, founder of "Friends of Amanda Knox" told CBS News, "We want her to be able to have space and have a re-entry and adjust and have the transition be a peaceful one and a restful one. She's got some healing to do from the trauma of all this. But I think she can get through it."

Amanda Knox said when she arrived in Seattle, "My family is the most important thing to me right now and I just want to go and be with them."

Curt Knox told "The Early Show on Saturday Morning" that his daughter is doing very well. "She's a lot happier and you can see just a huge weight off her shoulders now that, you know, she was found completely innocent of all the charges," he said. "It's kind of like people finally believed her, and that is a huge weight off your shoulders in this circumstance."

Though the jury overturned her murder conviction, the judge upheld Knox's conviction on a charge of slander for accusing bar owner Diya "Patrick" Lumumba of carrying out the killing of Meredith Kercher in 2007. He set the sentence at three years - meaning for time served - and a fine of 22,000 euros (about $29,000).

"48 Hours Mystery" airs Saturday night at 10 p.m ET/9 p.m. CT, with a special look back on the Amanda Knox case. Check out a preview of "Amanda Knox: The untold story.
