About Miguel Ángel Félix Gallardo
Miguel Ángel Félix Gallardo (born January 8, 1946), is a Mexican convicted drug lord who was one of the founders of the Guadalajara Cartel, which controlled much of the drug trafficking in Mexico and the corridors along the Mexico–United States border in the 1980s. Félix Gallardo was arrested in 1989 on charges of ordering the murder of Drug Enforcement Administration (DEA) agent Enrique "Kiki" Camarena. He was serving his 40-year sentence at the Altiplano maximum-security prison but was transferred to a medium-security facility in 2014 due to his declining health. This proved to be extremely profitable for them, with some estimating that the trafficking network, then operated by Félix Gallardo, Ernesto Carrillo and Rafael Quintero, was pulling in approximately $5 billion annually. Working through informants, Camarena discovered cartel marijuana plantations in Zacatecas state. Thousands of farmers worked the fields at Rancho Búfalo, and the annual production was later valued at US$8 billion.
