its possible calautti was murdered for his history of being a deadbeat who never paid his debts. his refusal to pay large debts goes back to 2004. i have also read that it could be connected to the 'ndrangheta gambling feud starting around that time. carmine verduci was initially lumped into the 'revenge of vito' with his 2014 murder, turned out was entirely not true and was related to gambling in GTA.
