Raffaele Sollecito, the co-defendant in the Amanda Knox murder case, has claimed that he has proven his innocence by analyzing the social media networks, while the pretty UW student is mum on the issue.

London's The Telegraph gave Amanda Knox murder case update when it reported the completed thesis by Raffaele Sollecito, who analyzed social media patterns and found that people more often think he's innocent rather than guilty.

"On the day that we were convicted, my name was associated with the word 'innocent' twice as many times as with the word 'guilty,'" Amanda Knox's ex boyfriend Raffaele Sollecito said in an interview with Corriere della Sera newspaper.

He said that he studied his own case for his thesis called "Social Network Analysis and Semantic Proximity," which was written in English.

"What was interesting was that in the days after we were reconvicted, there was a complete inversion - for the justice system we were guilty, but on the web, or at least among those internet search engines that I studied, the interpretation was exactly the opposite," Amanda ex boyfriend Raffaele Sollecito claimed.

The Telegraph said that he received an 88 grade for his completed thesis.

But Amanda Knox is mum about the issue. The last time, she took to social media was on January 13, according to her Twitter account where she wrote: "I will not willingly submit myself to injustice #amandaknox."

Earlier, UK's Mirror offered Amanda Knox murder case trial update when it reported that Italian prosecutors have linked the student with cocaine dealers, as they claimed that one dealer has already been arrested based on the information they got from the UW student's phone.

The latest report was an attempt by Italian authorities to extradite the student back to Italy, the publication said.

Amanda Knox murder case trial lawyers asked Italy's Court of Last Resort to review conviction of the UW student on the murder of Meredith Kercher in 2007. The Court of Cassation might issue its ruling on the petition late this year.
