He is the owner and proprietor of Parnell's Soup Co.. During the second World War, his business boomed, thanks to his contract with the United States government. Parnell claimed to have produced and shipped out five million of cans of soup to the U.S. military, as rations and for mess halls. However, once the war was over, Parnell's sales began to decline and he had difficulty employing a sufficient workforce at the factory. Becoming increasingly desperate, Parnell resorted to hiring illegal immigrants such as Jorge Garcia Cruz and Sergio Rojas. However, Parnell didn't realize that the two of them were involved in a massive reefer operation and were using the factory as part of distribution.

Parnell was visited by Detectives Cole Phelps and Roy Earle. Both of them revealed that reefer was being distributed in soup cans, implicating his factory. Parnell gave Phelps his employee list, reluctantly revealing he was employing illegal immigrants. Parnell gave background information on Sergio and Jorge, and provided Phelps and Earle a brief tour of the factory. Phelps promised to ignore Parnell's immigrant misdemeanor, as long as they would keep out of trouble. The factory was later raided during the bust of the reefer ring.
- Earle insults Parnell, calling him "fatso" and "fat boy" (although the second insult is only heard if Phelps interviews Parnell poorly).
