He is an associate of New York crime boss Tom Stratford.
Rosetti drives to Atlantic City for New Year's Eve 1923, planning to attend a party thrown by his liquor supplier Nucky Thompson. He brings an entourage of five guards. His car breaks down in Tabor Heights and he murders a Good Samaritan for a perceived slight to his intelligence. His guards watch as he beats the man to death.
They arrive in time for the party but Nucky tells him that he will no longer supply him because he wants to limit his exposure. Gyp flies into a rage and storms out of the party. ("Resolution")
Gyp returns to Tabor Heights, planning to use the town's strategic location as the last gas station in New Jersey on the drive from Atlantic City to New York as a roadblock to bootlegger Nucky transporting shipments. Gyp has Tonino and at least ten others accompany him in setting up the road block. They stop a convoy led by Nucky's lieutenants Owen Sleater and Mickey Doyle. Rosetti thug 4 stands behind Gyp with a Thompson submachine gun as the rest of the gang reveal themselves. Gyp intimidates them into turning back with the show of force. ("Spaghetti and Coffee")
Nucky drives out to Tabor Heights to meet Gyp and negotiate an end to the blockade. Nucky has the local Sheriff Victor Sickles accompany him to the meeting. Nucky criticizes Gyp's tendency to take offence so easily but offers a compromise; a final shipment of liquor as a goodwill gesture and a fully paid night in Atlantic City.
Gyp is disappointed when Nucky sends Owen with his excuses at the pickup. Rosetti thug 4 stands behind Eli Thompson during the exchange. Owen delivers a good luck message from Nucky, garbling the pronunciation of the Italian phrase "Buona Fortuna" (meaning good luck) as "Bone for Tuna". As Gyp leaves town he lets the perceived insult fester, convinced that Nucky is being sarcastic and intends him to fail. He stops in Tabor Heights to refuel and Sheriff Sickles drives out to meet him. Rosetti thug 4 leans against a car chewing tobacco during the stop. Sickles wishes Gyp good luck. Gyp believes he is being insulted again. He douses the lawman in gasoline and then sets him alight, burning him to death as his gang watch. ("Bone for Tuna")
