It has been almost two years since 22-year-old Amanda Knox was imprisoned in Italy, accused with her ex-boyfriend of murdering her British roommate, Meredith Kercher, in a sex game accident.

Knox's mother, Edda Mellas, told CBS News Correspondent Maggie Rodriguez this morning that she is confident that her daughter's attorneys have handled the case well.

"The question is, were they able to overcome all the negative perceptions, you know, a year's worth of really bad press that was filled with lies," Mellas told CBS' "The Early Show".

The court is considering having an independent third party examine the evidence against Knox, a move that Mellas says would benefit her daughter's case. Several experts in the United States have already looked at the DNA, according to Mellas.

"It's terrible, it wouldn't be allowed in U.S. courts and it doesn't stand up to any standards," she said.

Though Mellas is confident that the trial is going well, she is also prepared for defeat. She told Rodriguez that she had been warned by several people that justice isn't always served in Italy right away.

"That's just how it works, just because you're innocent, you're not found innocent, at least at this first level."

A man from the Ivory Coast, Rudy Hermann Guede, was convicted in the crime and sentenced to 30 years in prison last year.
