The Italian court that reconvicted Amanda Knox this year issued a report today outlining a new theory in the 2007 murder of Meredith Kercher.

The Florentine appeals court's new theory, outlined in a 337-page report, was issued to support the January retrial that again found Knox, her ex-boyfriend Rafaelle Sollecito and Rudy Guede guilty in the fatal stabbing.

The judge's new theory is that Knox, Sollecito and Guede were taking drugs together at the apartment when Kercher and Knox began fighting. Guede, who is now serving a 16-year sentence, told the court Kercher accused Knox of stealing €300 from her bedroom.

According to the report, the argument escalated until Knox began stabbing Kercher in a fit of rage. Pointing to forensic evidence indicating two knives were used, the court concludes Knox, Sollecito and Guede committed the murder together.

Meredith was immobilized and was unable to put up any useful resistance due to the fact that she was overpowered by a number of aggressors and simultaneously stabbed with the blades.

The report's release means the defense attorney can now appeal the case to Italy's Supreme Court. If Knox is again found guilty, she could have to face an extradition fight.

Knox issued a statement today denouncing the evidence in the case and vowing to fight "kicking and screaming" against any extradition charges.
