Javier Barba-Hernández (d. 1986) was a Mexican lawyer turned enforcer, hired by the Guadalajara Cartel to combat the Mexican Federal Judicial Police (FJP) and the American Drug Enforcement Administration (DEA).
Hernandez acted as a warlord for Ernesto Fonseca Carrillo, Rafael Caro Quintero and Miguel Ángel Félix Gallardo.
Prior to his death he was wanted for questioning in the murder of DEA agent Enrique Camarena.
[1][2] Barba was killed on November 13, 1986[2] in a shoot-out with Mexican Federal Judicial Police in Mazatlán, Mexico.
The DEA believes this may be part of a cover-up as the FJP has refused to turn over his fingerprints for identification.
