Amanda Knox murder case update apparently confirmed her links with cocaine dealers, which authorities are trying to connect with Meredith Kercher's murder. Meanwhile, a biopic about the student's life is set to premiere at Toronto Film Festival.

The Italian newspaper Giallo reported updates on the Amanda Knox murder case when it unearthed a police report on January 19, 2008 which said that "during the course of the investigation into the Meredith Kercher, we have confirmed that a person whose initial is 'F' would occasionally supply drugs to Amanda Knox."

The report also alleged that Amanda Knox was sleeping with her dealer. Although the newspaper has not disclosed the name of the cocaine dealers, it confirmed that it "knows them."

The dealer, nicknamed "F," was described as a psychology student who met Amanda Knox during a train ride from Milan to Florence. They shared a joint together and continued their communication "before and after the murder."

Apparently, "F" was part of a major drug syndicate in Perugia and the investigation into the Amanda Knox murder case, particularly the convicted killer's mobile phone, allowed authorities to uncover the drug ring.

The Italian authorities might not be able to extradite her on the murder conviction, according to M. Cherif Bassiouni, Emeritus Professor of Law at DePaul University, who wrote in the Oxford University Press blog that Art. VI of the Treaty states that "extradition is not available in cases where the requested person has been acquitted or convicted of the "same acts" (in the English text) and the "same facts" (in the Italian text)."

However, the UK's Mirror said that she could be extradited if she's linked to a major drug ring under investigation.

Meanwhile, according to Variety, the Amanda Knox-inspired film "Face of an Angel" will debut at the Toronto Film Festival. The film stars Kate Berkinsale and Daniel Bruhl and will center upon the media circus surrounding the Amanda Knox murder case, according to the publication.
