Propaganda Due
A member of "Propaganda Due", Musumeci was convicted in 1985, along with other SISMI officers Francesco Pazienza and Giuseppe Belmonte, for embezzlement and criminal association. Musumeci and Belmonte were also convicted for possessing and transporting explosives. They tried to sidetrack the investigations on the 1980 Bologna train station bombing by simulating an attempt with explosives on a Taranto-Milan train, in January 1981 (the bombing was voluntarily thwarted by order of Musumeci).
