Luis Alberto Guerrero Reyes

Luis Alberto Guerrero Reyes (died 10 May 2004) was a Mexican suspected drug lord and high-ranking member of Los Zetas, a criminal group based in Tamaulipas, Mexico. He joined the Mexican Army in 1987, specializing in explosives, martial arts and grenade launchers. In 1999, he deserted the military and joined the Gulf Cartel under kingpin Osiel Cárdenas Guillén, becoming one of the first members of its newly formed paramilitary wing, Los Zetas. Like Guerrero Reyes, most of the first members of Los Zetas were ex-military. Los Zetas was responsible for providing security services to Cárdenas Guillén and carrying out executions on the cartel's behalf.

Known for his arrogance and violent behavior, Guerrero Reyes was a suspect in multiple murders, including those of his girlfriend and wife. Investigators suspect he was part of the commando group that assassinated kingpin Edelio López Falcón. Guerrero Reyes was also an instructor to new Zetas members, training them in combat and counter-insurgency. In 2004, he was killed in a drive-by shooting by unknown assailants along with four other people after he left a discotheque in Matamoros. His murder remains unsolved; it is not known if he was killed by his own cartel or by rival gangsters.

Early life and career Guerrero Reyes joined the Mexican Army on 1 March 1987, as an infantry soldier in the 70th Infantry Battalion.
