Comandante Méndez was an officer in the Mexican Federal Judicial Police. Despite having connections to the Guadalajara Cartel, Méndez frequently accompanied the DEA in hunting the members of the cartel.
Méndez was highly reluctant to make any major moves, and could only be bothered to bust a small weight of marijuana, usually "gifted" to the police by the cartels. At numerous times, Méndez leaks DEA intelligence to the cartel, and once to the boss Miguel Ángel Félix Gallardo himself.
