(Covers information from the D.C. comics)
Jackie was an Umbrella security guard employed one of the company's storage warehouses. He was known to his friends as "Jackie the Joker" due to his sense of humor. He and Earl were on duty the night Dexter Whitlam sneaked in. Although they chased after Dexter, they decided that since he was only a teenager there was no point in pursuing him. Only afterward did the pair notice that a G-virus sample was missing. They decided not to report the incident to headquarters. When this was found out, Jackie was killed along with Earl by Mr. Venk.
