 At least one high ranking investigator believed most of those who carried out murders for Cosa Nostra answered solely to Bagarella, and that consequently Bagarella actually wielded more power than Bernardo Provenzano who was Riina's formal successor.Provenzano protested about the terrorist attacks, but Bagarella responded sarcastically, telling him to wear a sign saying "I don't have anything to do with the massacres".Bagarella stopped ordering murders some time before his own capture, apparently due to the suicide of Vincenzina.
