An Italian jury has overturned the murder conviction of Amanda Knox.  The young American is now free after nearly four years in prison for the death of her British roommate. 

Knox collapsed in tears after the verdict was read in court Monday afternoon.  She was sentenced to 26 years in prison two years ago for the murder of Meredith Kircher, with whom she shared an apartment.  She told the appellate jury she had nothing to do with the death of Kircher.  The jury upheld the defamation conviction after she blamed a club owner for Kircher’s death.
