What was the name of the Mafia faction headed by the person responsible for the assassination of Placido Rizzotto?
Placido Rizzotto Placido Rizzotto (Corleone, January 2, 1914 – March 10, 1948) was an Italian socialist peasant and trade union leader from Corleone, who was assassinated by Sicilian Mafia boss Luciano Leggio. Pieces of Rizzotto's mutilated body were discovered two years later at the bottom of a cliff with his limbs chained up, and a bullet hole in his head. When he was killed, Rizzotto was doing activist work with farm laborers, trying to help them take over unfarmed land on large estates in the area.
Pentito Italian term pentito (] ; "repentant"; plural: "pentiti") is used colloquially to designate people in Italy who were formerly part of criminal or terrorist organizations, and who, following their arrests, decided to "repent" and collaborate with the judiciary to help further investigations. The judicial category of "pentiti" was originally created in legislation passed by the Italian government in the 1970s to combat violence and terrorism during the so-called Years of Lead. The correct technical name used for them is "collaborators of justice" (Italian: "collaboratori di giustizia" ). In the wake of the Maxi Trial in Palermo in 1986–87, and after the testimony of Tommaso Buscetta, the term came into widespread use in Italy for all former members of the Sicilian Mafia who had abandoned their organization and started helping investigators.
