The teacher referred Ross to his supplier, Ivan Arguellas, who offered to keep Ross supplied. Arguellas was able to provide larger quantities at a better price, and Ross quickly went from dealing in grams of cocaine to dealing in ounces. About eight months after becoming Ross's supplier, Arguellas was shot in the spine, resulting in months of hospitalization that forced him out of the cocaine business. His brother-in-law Henry Corrales took over the business, but was not enthusiastic about the trade and had failed to make any connections of his own to suppliers.
