The parents of Amanda Knox, the American girl charged for murdering her British roommate, went on Oprah today to discuss what life has been like after her daughter was imprisoned.

Amanda Knox was found guilty of murder charges and was sentenced to 26 years in jail. She was studying in Italy with her boyfriend who was also convicted in December of Knox’s roommate’s murder in the Umbrain University town of Perugia.

While on the show, Knox's father, Curt Knox, walked away from Oprah Winfrey's cameras because his own emotions overwhelmed him.

There are days where the visits are really, really nice, and then there are days when it's extremely tough, and you do the best you can, Curt Knox told Winfrey.

She asks, 'Why is this happening to me? I haven't done anything, I've told the truth.' How do you explain that to her? said Mellas. How do you explain that mistakes happen and she's in the middle of a massive mistake?

The case received a lot of media attention, both nationally and internationally.
