Convicted Cosa Nostra treasurer Pippo Calo (R) and a lawyer appear video-linked with Rebibbia prison's courtroom in Rome, during the opening of the trial for the 1982 killing of Italian banker Roberto Calvi, October 6, 2005. More than two decades after Roberto Calvi was found hanging under London's Blackfriars Bridge, five people stood trial in Italy on Thursday accused of murdering the man known as "God's banker" for his close Vatican ties. A Sicilian mobster, a Sardinian financier and three others are accused of murdering Calvi, whose death in June 1982 was initially ruled a suicide. Rome prosecutors now say the Mafia killed him for stealing from them and from Italian financier Lucio Gelli, who was the head of the shadowy P2 masonic organisation. REUTERS/Max Rossi
