It´s possible I guess that Coco served in the administration on acting basis while the bosses were on trial. But according to a government report I just read, Macaluso was the acting consiglere around 1987 til 1988, when he was demoted. He also served, according to this same report, as the acting underboss during this time. Could be that Coco served in this role, before Macaluso. But I can´t say for sure.
