Jerry was Tony Montana's banker, who did heavy business with Tony, laundering the profits from his drug trade. He was one of the guests at the wedding of Elvira Hancock and Tony Montana. However, as Tony's empire grew and henchmen were literally delivering duffel bags full of cash to the bank, Jerry became worried about all the attention this was attracting. He warned Tony there was only so much dirty money he could launder and said he would need to raise rates to keep this going. Tony accused Jerry of being grabby and threatened that he was not the only game in town, considering offshore banking. Jerry warned Tony that most Caribbean nations have unreliable banking and firmly said he should keep his business with him, but Tony refused to heed that advice, Manny Ribera, Tony's second-in-command, suggested that they should go to another banker, named Seidelbaum, which set disastrous events in motion that would ultimately lead to Tony's downfall.
Scarface - The World Is YoursEdit
In the game, set 3 months after the events of the movie, Tony turns to Jerry again and asks him to be his accountant once more. It is unknown if Jerry knew of Tony going to Seidelbaum behind his back. More likely, it seems that Jerry was aware of the gun battle between Sosa's men and the seizure of Tony's assets by the law, as Jerry is uneasy of doing business with Tony again. However, Jerry ultimately agrees to resume business with Tony as he has faith in him.
