It is through the statements of the collaborators that the criminal depth of Francesco Messina Denaro is finally outlined. Balduccio Di Maggio is the first of all to indicate him as head of the province of Trapani. Di Maggio said that father and son were the perpetrators of the murder of four people in the countryside of Partinico in 1989. For this crime they were sentenced to life imprisonment. This is the only murder, among those known, in which father and son participate together and it is a sort of handover. In a few months Francesco Messina Denaro died.
