Colonel Juan Garcia Cortez is a colonel from an unknown war. He and Tommy meets at a party on his yacht. Colonel Cortez discvers that his main henchman, Gonzalez, has given the information to someone (revealing in Vice City Stories to be Ricardo Diaz, as Gonzalez was forced by Diaz to reveal all the information about the Colonel's drug dealing). Cortez then tells Tommy to kill him using a chainsaw. Colonel Cortez seems to have a dislike for the French Secret Service when he steals chips containing information on weapons. The French secret Service invade the area Cortez was docked with his yacht. Tommy recognises Cortez as an honourable man and helps him escape.
