From the first investigations it would seem that Paolo Salvaggio was linked to the Papalia clan or a family of 'Ndrangheta which has long been present in the territory of Buccinasco and Corsico. But there is more: the victim, nicknamed "Dum Dum", was among the suspects of the 2013 South Park anti-mafia operation. The investigations then revealed that he was doing business with Colombian narcos to get drugs. Once in possession of drugs, his contacts were mainly with the bosses of the clan of 'Ndrangheta Barbaro-Papalia di Platì and with the members of the Magrini clan of the Sacra Corona Unita .
