Gustavo was born in the town of San Juan del Rio, but lived on the countryside. His father was in a Mariachi band, and would often be gone for some of the week. His mother was a farmer, and so he'd farm with his mother and sell their fruits at the farmers market. At the age of 24, his mother would die to heart complications, and his father would soon follow, dying of old age. He would see his farming skills as a sort of tool, and saw how much more money his farming peers would make selling weed. He would move his way to the state of Sinaloa, where he would begin to go under a wing of farmers in the Marijuana drug trade. After a couple of years, and a thinning of his farming peers, he would begin to foresee his own farm, so long as he grew for a notorious cartel, and would do so for about 6 years, where he would be asked to pioneer the drug growing in the South Zagoria region of Chernarus. He would do so, as saying no would mean death, and flew out to Chernaurus to start a new life. 2 months into his new job, and now an official citizen of Chernarus, would begin to flee to Northern South Zagoria due to a incoming battle between the Chedaki and Chernarussian government. On his way to his new job-site, he would pull up to a mob of people tearing into 7 armed men, beating them mercilessly to death. He would take the car onto a offroad trail, arriving at his location and turning on his radio. Upon hearing that the mass amounts of rioters were actually infected individuals, he would realize that he'd be stuck there for a unseen amount of time, and decided his new job would be to just survive.
