For more than 30 years, the unemployed ex-wife and ambitious son of Italian drug trafficker Giacomo Tamburello relied on an international network of bankers, lawyers and brokers to amass a $230 million fortune and shield it from authorities, according to Italian prosecutors.

Their recent investigation — which has made international headlines because of Tamburellos’ alleged links to one of Italy’s most powerful mafia clans — led to the trio’s arrest in May and the seizure of assets spread across nine jurisdictions.

Prosecutors found that Tamburello earned millions primarily through the illicit trade of hashish from Morocco and shared 10% of the revenues with Matteo Messina Denaro, a notorious mafia boss until his capture and death in 2023. Starting in the 1980s, Tamburello allegedly laundered the funds with the help of his then-wife Maria Antonina Bruno and, later, their son Luca Tamburello, who studied banking and international finance at elite European business schools.
