Fernando Delgado honored his friend's wishes and sent Andrea to America to get an education. She returned to Chile in 2002, living at the Delgado villa for a few months before moving to Santiago where she met up with Rico Delgado and formed a friendship with him. Determined to honor her father's wish and her uncle's expectations, she got a job in the advertising industry and worked there for a couple of years as a marketing executive. But, tragedy struck as Fernando Delgado and his son were killed in an apparent accident in 2004. The effective dismantling of the cartel following their deaths, however, brought back the spectre of the past and Martinez realized that some hidden hand was behind the deaths. Worried for her life, she fled Chile and ended up in Colombia with Rico Delgado and his brother Hector.
Together, the trio started what would eventually become the reformed Delgado Cartel - quickly starting a new business and getting Martinez's hands dirty by creating a series of legal fronts for what would quickly grow into a substantial criminal empire.A vital part of Delgado's organization, Andrea Martinez travels the world under a range of assumed identities, expanding the business and making sure everything runs smoothly. Where Rico Delgado is responsible for the trafficking side of the business, Martinez is responsible for the business side of things. She engages in the bribing of officials, extortion and information gathering that ensures the other cartels are kept in check, and she keeps the public eye away from Rico Delgado, through her magnificent skilled at spinning stories and extorting people based on the information she gathers through networks like IAGO."

- Don Fernando Delgado was Andrea's uncle according to her in-game profile, which would make Hector and Andrea cousins (albeit possibly only step-cousins, if Andrea's father married into the Delgado family after Andrea was born).
