Final arguments for Knox appeal

Posted: Updated:

PERUGIA, ITALY- Tomorrow we'll be watching a courtroom in Italy.

That's where a University of Washington student hopes to get her murder conviction overturned.

The Italian court convicted Amanda Knox, her boyfriend at the time, and a third man nearly two years ago for the murder of Knox's roommate.

Knox has reason to be optimistic because this past summer independent forensic experts appointed by the court concluded the DNA evidence used to convict her was unreliable.

The experts also say police scientists made several errors. 

With experts shooting holes in the DNA evidence, Knox's family believes the Italian prosecutors no longer have a case, and they're optimistic that after four years in jail, Knox will be coming home soon.

A Legal expert in Perugia says if acquitted, Knox could be released immediately.
