[1][2] According to the investigators, the boss, even during his detention, had maintained the regency of the mafia family, directly managing the extortion to companies from the prison and receiving the proceeds to be poured into the "cash" of the association, and this through collaboration of his wife Antonella Di Graziano.

Released from prison in 2016, Francesco Domingo was subjected to the preventive measure of the special public security surveillance with the obligation to stay in the Municipality of Castellammare.

It is precisely because of these characteristics and the extremely dangerous criminal profile of the boss that, at the time of his release, the investigative activity against him was started, appearing highly likely that Domingo, returned to freedom, would again acquire control of the mafia family.

The Castellammare family was dedicated to the control of economic activities through intimidation and extortion against building and agricultural entrepreneurs.

[3][4] According to various investigations, the boss has maintained close relations with the branches of the Cosa Nostra in the United States, in particular with the Bonannos, in fact, the affiliates of the New York family made numerous visits to Domingo's villa, in the Gagliardetta district.
