Three people are being held under suspicion of murdering British exchange student Meredith Kercher in Perugia. What makes this murder investigation different to others is that it comes with a Web 2.0 angle, as investigators trawl through Facebook and Myspace accounts in order to obtain clues.
The use of social networking as a tool for criminal investigation is a logical step, as most victims know their killers (in the United States for example, only 14% of murders are committed by strangers). That being the case, more and more police investigations will move online to try to get an idea of potential perpetrators from pictures, friends lists and mailing lists.
