On this day‬ in 1979 the Italian lawyer, Giorgio Ambrosoli was gunned down by three Mafia hitmen while he was investigating Michele Sindona (a banker known as ‘The Shark’). Worried that Ambrosoli would expose everything to the Police, Sindona commissioned the hit.

Hours prior to Ambrosoli’s death, he was also talking to the Police Chief, Boris Giuliano, about documents he had discovered which connected Sindona to the Mafia. 10 days later the Mafia gunned down the Police Chief.

Sindona was eventually sent to prison in 1984, two years later he was poisoned with cyanide while drinking coffee in his cell.

Ambrosoli was 45 at the time of his death.

On this day in 1979, Italian lawyer Giorgio Ambrosoli was gunned down outside his Milan apartment by three Mafia hitmen, becoming one of the most prominent victims of the deadly intersection between organised crime, corrupt banking, and political power that defined Italy's turbulent postwar decades. He was just 45 years old.

Ambrosoli had been appointed by the Italian government as the official liquidator tasked with unravelling the financial empire of Michele Sindona, a Sicilian banker of extraordinary cunning who had become known throughout Europe and America as "The Shark." Sindona was no ordinary financier. His network of banks and shell companies stretched from Palermo to New York, and his connections ran deep into the Sicilian Mafia, the Vatican Bank, and the shadowy Italian masonic lodge known as Propaganda Due, or P2. In the United States, he had cultivated relationships with the American Cosa Nostra, serving as a money laundering conduit that helped funnel narcotics profits through legitimate financial institutions — a pipeline that connected Old World organised crime to the same networks that figures like Lucky Luciano had helped establish decades earlier when building the transatlantic heroin trade after the Second World War.

For years, Ambrosoli painstakingly pieced together Sindona's labyrinthine frauds, fully aware of the danger his work attracted. In letters to his wife, he wrote with remarkable composure that he understood the price he might pay. On the evening of 11th July 1979, hours before his murder, he met with Boris Giuliano, the highly respected Chief of Palermo's flying squad, sharing documents that directly tied Sindona to Mafia money flows. The killers were waiting when Ambrosoli returned home that night. Ten days later, on 21st July, Giuliano himself was shot dead outside a Palermo bar — the Mafia erasing both threads simultaneously with brutal efficiency.

Sindona eventually faced justice, though it arrived slowly. He was convicted in the United States in 1980 for bank fraud and later extradited to Italy, where in 1984 he received a life sentence for ordering Ambrosoli's murder. In March 1986, he was found dead in his prison cell at Voghera, poisoned with cyanide that had been stirred into his morning coffee — whether by his own hand or another's remains a matter of considerable debate.

Giorgio Ambrosoli is remembered in Italy as a symbol of civic courage and institutional integrity, a man who knowingly sacrificed his life rather than abandon his duty. His story stands as a stark reminder of how deeply organised crime had embedded itself within the legitimate structures of power during one of Italy's darkest chapters.
