When Toto Riina (Calogero's brother in law) gets out of prison around 1856, he reconnects with Bernardo Provenzano, Luciano Leggio, and Calogero Bagarella, who had become powerful.
The assassins of the brothers Marco Marino and Giovanni Marino, and of Peter Maiuri, are said to be, though not formally, Bernardo Provenzano, Calogero Bagarella, and Giuseppe Ruffino, as well as Leggio. Carmelo lo Cascio reports being an eyewitness to Provenzano and Bagarella fleeing the scene of the killing of the three, on 6 September 1958.
Calogero's father, Salvatore, is sent to confinement in Northern Italy from 1963 to 1968 for Mafia-related crimes.
Calogero, his older brother Leoluca, and their father, are defendants in the 1969 Mafia trial in Bari, Italy. At the time, Calogero is on the run (latitante). All 64 defendants are acquitted in June, when the judge and juries lives, and those of their families, are anonymously threatened.
Calogero is killed later that year by Michele Cavataio, on December 10, 1969. A hit squad that includes Calogero, Bernardo Provenzano, and mafiosi from other towns, attacks Cavataio in Palermo, in retaliation for Cavataio's engineering of the first Mafia war in Palermo, in 1962. Calogero is killed in the attack.
