Beginning in 1998, the Calvi affair was back in the news when the family of the late financier had his body exhumed. The new autopsy confirmed that Calvi was murdered elsewhere, and his corpse then hanged from beneath Blackfriar's Bridge. Investigators caught a major break in the case when in December, 2002, Mafia kingpin Antonio Giuffee told police that Calvi was murdered in part for absconding with mob money being laundered through Banco Ambrosiano.
It is known that as the bank collapsed, Calvi approached friends in the Vatican to cover losses. He allegedly told associates in the Holy See that unless Ambrosiano was protected, he would expose powerful men in Italian finance and politics. Calvi disappeared the day after those frantic phone calls to the Vatican, along with the briefcase packed with sensitive documents.
Leading the effort to solve the mystery of Roberto Calvi's murder has been Carlo Calvi, the banker's son who left Italy in 1977 and now lives in Montreal, Canada.
His father, says Carlo Calvi, "was a dynamic businessman but not a good judge of people."
Police and prosecutors have zeroed in on four suspects now on trial: Flavio Carboni; his former girlfriend Manuela Kleinzig; and Pippo Calo and Ernesto Diotallevi, two "fixers" with close ties to the Mafia.
There are concerns, though, that the four could be scapegoats for a wider conspiracy, and that significant aspects of the case implicating the Vatican, government agencies, other banks and special interests could be conveniently ignored. The judge in the current proceedings, Mario D'Andra, has been vehement in demanding a swift trial.
"Let's try to keep in mind that this is a trial about facts that happened almost 24 years ago," he declared. And Carboni's attorney, Renato Borzone has argued that there is no proof of his client's participation in any murder, charging Italian prosecutors with "relying on a phony testimony by turncoats" in order to make their case.
On the opening day of the proceedings, Borzone told the court, "Today, a new battle begins to find the truth about Calvi's death.
Carlo Calvi theorizes that while mobsters may have executed his father, "the murder was organized by politicians. The Mafia had simply the role of carrying out the murder."
Questions linger not only about who killed Roberto Calvi, but who ordered the murder.
