Source-derived summary

Los Ántrax is a large enforcer unit and hit squad for the Sinaloa Cartel, a major crime syndicate based in the Mexican state of Sinaloa. The group was led by the drug lords Jesús Victoriano (alias "El 20"), José Rodrigo Aréchiga Gamboa (alias "El Chino Ántrax"), René Velázquez Valenzuela (alias "El Sargento Phoenix"), among others, and they are responsible for a number of homicides and for providing armed security services to Ismael El Mayo Zambada. The gang operates in the capital city of Culiacán, Sinaloa, where its members conduct homicides and violent attacks. Los Antrax is the Sinaloa Cartel's largest and deadliest enforcer unit.

Etymology

The name of the group is inspired from the bacterium spores anthrax, although the Sinaloa state authorities have never officially recognized the group's existence.

History

Los Ántrax worked as the security force of the drug lord Ismael El Mayo Zambada (now arrested), who leads the Sinaloa Cartel along with Joaquín El Chapo Guzmán (now also arrested). Several homicides have been attributed to the gang, which was led by a drug trafficker named Rodrigo Arechiga Gamboa (El Chino Antrax), who died on May 15, 2020, and his right-hand man Jesus Peña (El 20). Peña escaped from a prison in Sinaloa on March 16, 2017, with four other suspects, including alleged Ántrax member Rafael Guadalupe Félix Núñez (alias "Changuito Ántrax") and Juan José Esparragoza Monzón, son of Juan José Esparragoza Moreno.

Tubutama, Sonora shooting

A fierce gunfight between members of the Sinaloa Cartel (with the backing of Los Ántrax) and the Beltrán Leyva Cartel (with the support of Los Zetas) left about 30 dead in the town of Tubutama, Sonora in northern Mexico on 1 July 2010. The drug gangs clashed just a few miles across the international border from the U.S. state of Arizona – an area notorious for being a smuggling route for narcotics and human trafficking.

Editorial analysis

Why this record matters

The phrase “enforcer gang of the Sinaloa Cartel” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q6683472. The first chronological checks are 2020, 2017 and 2010.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
