Evidence against American student Amanda Knox and her ex-boyfriend in the murder of her college roommate in Italy will be presented tomorrow amid a daunting web of questions, the Guardian reports. For starters, jurors need to determine whether more than one person killed British student Meredith Kercher—a particularly vital issue, since one man has already been convicted of her gruesome murder.
The court must also weigh whether Knox and her boyfriend's behavior was suspicious, and whether the forensic evidence is as solid as police claim. The motive for the killing also remains a mystery. Prosecutors suggest that the pair plotted with the convicted man to kill Kercher after she refused to join them in a drug-fueled orgy—a pact between virtual strangers that even the judge who sent Knox to trial acknowledged was highly implausible.
