Is Domenico Terrasi the current boss of Catolica Eraclea in the Sicilian Mafia hierachy?
Yes he is.
Thank you, carmela, for the corroboration.
One more thing...as a side note: with regard to Andrea Amodeo, I've seen it written on line sometimes that he was the one responsible for killing police officer Giuliano Guazzelli, when in fact it was Gerlandino Messina that killed that officer.
