Amanda Knox Trial: the Unanswered Questions

The verdict was swift, but the 11-month-long trial of Amanda Knox and Raffaele Sollecito, convicted of murdering British student Meredith Kercher, failed to answer these nagging questions, the Telegraph reports:

• What was the motive? Prosecutors said it was a four-way sex game, but the perpetrators barely knew each other. The notion of virtual strangers getting together for a brutal slaying still strains credulity.

• What about the 'she-devil' theory? After the orgy-gone wrong theory, prosecutors charged that Knox murdered Kercher in rage over criticism that she was a bad flat-mate. Does that really stack up against the alternative—that Rudy Guede, drug dealer and suspected thief, raped and murdered Kercher on his own?
• Wasn't the DNA evidence sketchy? The Sollecito DNA on the bra clasp was tiny, and it was found on the floor, 7 weeks after the murder, leading to a high risk of contamination.
• Did they have the wrong murder weapon? The knife didn't match the wounds, or a bloody smear on the bedclothes, and Knox's DNA on it could have come from paring an apple. Kercher's DNA was so iffy it wouldn't have been admissible in many courts.
• Why did Guede change his story? In a cell-phone call when he was on the run, he told a friend that Knox was not in the apartment the night of the murder. It was months after his arrest that he said she and Kercher had argued.
