The Court of Cassation, Italy's highest court of appeal, overturned the acquittal of Amanda Knox. The comely Knox was a 20-year-old American exchange student in Perugia when her British flat-mate Meredith Kercher was murdered in 2007. Initially, she was convicted on the basis of demonstrably flawed DNA evidence but then acquitted after the appeal court found that the charges against her were "not corroborated by any objective element of evidence."
As I show in The Annals of Unsolved Crime, there was not a scintilla of evidence that placed her at the murder scene. Nor was there a witness.
