The suspect of the investigators is that whoever physically killed him is only a hit man and that the principal (or principals) has a "high caliber" criminal: someone to whom Diabolik may have "stamped his feet" in the division of the territory, someone who he was not afraid to kill an icon of the Lazio cheer, putting himself against a large chunk of Rome. Someone who was not afraid to shoot in the light of day, in a public place, perhaps to give a "signal" to all those who gravitated around Piscitelli, considered by many as a charismatic leader (not only among those who frequent the northern curve ).
"He had drug debs. Since seized him all the assets in 2016, including the villa where he lived, he never got up again ". To say this is Vincenzo, a former ultra of Lazio, and a great friend of Diabolik.
