Ernesto Fonseca
Ernesto Fonseca, also known as 'Don Neto,' was a prominent Mexican drug lord and one of the founding members of the Guadalajara Cartel in the early 1980s. He played a significant role in the marijuana and later cocaine trade, collaborating with other notorious figures like Rafael Caro Quintero and Miguel Ángel Félix Gallardo. Fonseca was implicated in various criminal activities, including the murder of DEA agent Enrique 'Kiki' Camarena, which brought intense scrutiny from U.S. law enforcement. He was arrested in 1985 and sentenced to prison, becoming a key figure in the history of Mexico's drug trafficking landscape.
