Shrewd operator El Mayo, El Chapo’s flashy heir Joaquin Lopez: Who are Mexican drug lords nabbed by US?

United States authorities have nabbed two key figures at the helm of the infamous Sinaloa cartel. The co-founder of the Mexican Sinaloa cartel, Ismael “El Mayo” Zambada, and one of El Chapo’s sons, Joaquin Guzman Lopez, were arrested on Thursday (July 25) in Texas.

This high-profile detention may not only reshape the Mexican criminal landscape but also lead to violence in case a potential power-grab war tussles ensue.

Here’s an in-depth look at who El Mayo and Joaquin Lopez are, and what their arrests might mean.

El Mayo: The shrewd trafficker

Ismael “El Mayo” Zambada, now believed to be in his seventies, is one of Mexico’s most consequential traffickers. A co-founder of the notorious Sinaloa Cartel alongside El Chapo, Zambada has been a key figure in the international drug trade for decades. Unlike many of his contemporaries, El Mayo has shunned the limelight, operating from the shadows with a blend of cunning and discretion that has enabled him to evade capture until now.

His reputation as an “old-school” narco is well-earned; he has avoided the ostentatious displays of wealth and power that often lead to the downfall of many in his line of work. He is understood to be a shrewd operator.

Zambada’s arrest marks a significant milestone for US authorities, who had placed a $15 million bounty on his head. His capture is expected to create a power vacuum within the Sinaloa Cartel, an organisation that has recently become the primary target for US law enforcement due to its significant role in the fentanyl drug trade.

Fentanyl, a synthetic opioid, has become the leading cause of death for Americans aged 18 to 45, intensifying the urgency to dismantle the cartel’s operations.

Joaquin Guzman Lopez: The flashy heir

In stark contrast to El Mayo’s low-profile persona, Joaquin Guzman Lopez, in his thirties, embodies the new generation of narcos. As one of the four sons of El Chapo— collectively known as Los Chapitos (Little Chapos)— Joaquin Guzman Lopez has inherited not just his father’s empire but also his penchant for flamboyance.

This younger cadre is notorious for their flashy lifestyles and propensity for violence, characteristics that have made them conspicuous targets for law enforcement.

Joaquin Guzman Lopez’s arrest follows the detention and extradition of his brother, Ovidio Guzman, to the US last year. The Guzman siblings have been at the helm of their father’s faction of the Sinaloa Cartel, continuing its operations with a blend of brutality and bravado that starkly contrasts with Zambada’s more calculated approach.

Joaquin Lopez had a $5 million bounty on his head.

A landmark operation

Zambada and Guzman Lopez were detained after landing in a private plane in the El Paso area, according to US officials.

US Attorney General Merrick Garland emphasised the significance of the arrests, stating that the two men face multiple charges for heading the cartel’s criminal operations, particularly its deadly fentanyl trafficking networks.

Implications for the Sinaloa Cartel

The arrests of Zambada and Guzman Lopez could trigger significant instability within the Sinaloa Cartel. Historically, the detention of key figures has led to violent power struggles as factions vie for control. The relationship between Zambada and Los Chapitos has been fractious since El Chapo’s extradition in 2017, and this recent development may exacerbate tensions.

The cartel’s operations, which span over 50 countries, are expected to face disruptions as a result of these high-profile arrests. US authorities, including the Federal Bureau of Investigation (FBI) and Homeland Security Investigations (HSI), who conducted the joint operation, have focused recent efforts on combating the flow of fentanyl and precursor chemicals that fuel the cartel’s illicit activities.

The future of the Sinaloa Cartel now hangs in the balance. The potential for infighting and the emergence of rival factions may lead to further violence. The possibility of violence is not only within the cartel, but also across the broader Mexican criminal landscape. Perceived weakness in the Sinaloan cartel may open it up to attacks from other groups.
