Mauro De Mauro (Italian pronunciation: ['mauro de 'mauro]; 6 September 1921 β disappeared 16 September 1970) was an Italian investigative journalist.
Originally a supporter of the Fascist regime of Benito Mussolini he eventually became a journalist with the left-leaning newspaper L'Ora in Palermo.
He disappeared in September 1970 and his body has never been found.
The disappearance and probable death of the "inconvenient journalist" (giornalista scomodo) β as he became known as a result of his investigative reporting β remains one of the greatest unsolved mysteries in modern Italian history.
Several explanations for his disappearance are current.
One is related to the death of the president of Italy's state-owned oil and gas conglomerate ENI, Enrico Mattei.
Another is that De Mauro had discovered drug trafficking between Sicily and the United States.
