Gio Amato is the brother of criminal Michael Amato.
History[]
Gio taunted Seamus O'Meara at Teddy Silas' bar, which angered Seamus and resulted in him punching Gio in the face. Angered by Gio's taunts towards Seamus, Eamon Murphy ordered a hit on Gio's brother Michael, which Slootmaekers reported to Stabler and Bell.
Despite the hit being made, Michael tried to murder Eamon during a boxing match at Teddy's bar by shooting him in an act of revenge for Gio but Eamon managed to dodge the bullet just in time. (OC: "Punch Drunk")
