Mexican Cartel Strategic Note No. 30: “El Marro” – José Antonio Yépez Ortiz Leader of the Cártel Santa Rosa de Lima (CSRL) Arrested in Guanajuato
Nathan P. Jones, John P. Sullivan, and Robert J. Bunker
José Antonio Yépez Ortiz (aka “El Marro”) was arrested by elements of the Mexican Army (Sedena) in Guanajuato on Sunday, 2 August 2020. “El Marro,” which means the sledgehammer or mallet, is the leader of the Cártel Santa Rosa de Lima (CSRL). The CSRL are widely known for their role as ‘huachicoleros’ or participants in the illicit fuel trade. The CSRL has been embattled for the past year as government forces sought its leader’s arrest and it fought against its rival the Cártel Jalisco Nueva Generación (CJNG) for control of Guanajuato’s illicit economy.

“El Marro” (The Mallet), Yepez was arrested in the early hours of Sunday by soldiers and state officials during a raid on a house in Guanajuato, a central state that has become the main flashpoint of record gang violence, authorities said…
…Guanajuato’s government said security forces captured Yepez and five other suspected gang members in a village called Franco Tavera in the Santa Cruz de Juventino Rosas municipality, a few miles north of where the Santa Rosa de Lima Cartel was born.

Mexican authorities on Sunday arrested the leader of the Santa Rosa de Lima cartel, a gang known for stealing millions of dollars in fuel from government pipelines and for turning once-peaceful Guanajuato state into one of the most dangerous regions in the country…
…Yépez Ortiz, 40, first made headlines for reportedly stealing more than $1 million worth of fuel a day from the many pipelines radiating from a government-owned oil refinery in the city of Salamanca. His cartel became the most powerful of the country’s many fuel-theft gangs, known as huachicoleros, and later branched out into other illegal enterprises, including extortion and local drug sales.
In 2017, his group ran afoul of the Jalisco New Generation cartel, one of the most powerful criminal organizations in Mexico, led by Nemesio Oseguera Cervantes, known as “El Mencho.”

While the arrest of José Antonio Yépez delivers a major blow to a cartel, analysts say officials lack a cohesive strategy against debilitating crime…
…The Santa Rosa de Lima cartel began its reign in the state of Guanajuato, pilfering oil from pipelines that crisscross that area of central Mexico and siphoning off amounts estimated at one point to be valued at nearly $2 million a day.
As the head of a small start-up cartel, which analysts say was largely run as a family crime group, Mr. Yépez showed uncharacteristic pluck, challenging both the government and much larger and more diversified criminal groups.
In emotional videos, Mr. Yépez has often lashed out at his enemies and even threatened the president himself if federal troops were not withdrawn from his native state, where they had been sent to fight fuel theft.

Termina así una etapa negra en Guanajuato: la década del Marro.
Lamentablemente, queda un infierno por venir: la disgregación del Cártel de Santa Rosa en pequeñas y feroces células, o bien, la absorción de su estructura por un nuevo grupo dominante: el Cártel Jalisco Nueva Generación, que dirige Nemesio Oseguera, El Mencho, y que lleva años peleando por el control de los ductos.
Expertos en temas de seguridad creen que habrá en el estado un nuevo coletazo de sangre: ya sea por el reacomodo del Cártel de Santa Rosa, o por la “limpia” que el Cártel Jalisco emprenderá en los lugares que El Marro deja acéfalos.
Para evitar que el fuego se avive, debe llegar un nuevo golpe, esta vez del lado del Mencho. Pero sobre todo es preciso que se desnuden las redes de corrupción que desde Pemex y el sindicato hicieron posible a José Antonio Yepez, El Marro.

The capture of José Antonio Yépez Ortiz (“El Marro”) throws the balance of power in Guanajuato into turmoil. The situation in Guanajuato has been characterized by an intense paramilitary conflict between the Cártel Santa Rosa de Lima (CSRL) led by “El Marro” and the Cártel Jalisco Nueva Generación (CJNG) led by Nemesio Oseguera Cervantes (known as “El Mencho”). The situation in Guanajuato can be depicted as a three-way contest for local supremacy involving the CSRL, the CJNG, and elements of the state (including the government of Guanajuato state and its constituent municipalities, as well as the federal government).
At first glance, Guanajuato seems an implausible location for an organized crime hotspot, but its oil pipelines and refinery at Salamanca have made it a key battleground in a highly diversified organized crime landscape, which now includes huachicoleo (oil theft) as a core component. The arrest of El Marro may have significant implications for the levels of violence in the Guanajuato and the balance of power in Mexico’s criminal economy. If the CJNG gains control of Guanajuato, this could alter the nature of the illicit petroleum trade, drug trafficking, and the relationship between the CJNG and other criminal cartels with elements of the state. If the CSRL is able to survive El Marro’s capture and transition leadership, the contest between the CSRL and CJNG may continue.
Mexican organized crime groups such as Los Zetas diversified their drug portfolios into new activities like extortion and oil theft, as scholars have pointed out for some time now. Mexico had long derived high percentages of government revenue from the state oil monopoly Petróleos Mexicanos (Pemex), with that percentage peaking at 40% of government revenues in the 2000s under the Vicente Fox Sexenio (administration). With the rise of oil theft and declining production (due in part to reduced exploration), that percentage began to drop and Pemex suffered from significant internal theft and clandestine pipeline taps. Other Mexican organized crime groups moved into the oil theft business and the CSRL emerged. The CSRL was primarily involved in hydrocarbon theft and then diversified into other criminal enterprises. Since the 2010s, the number of clandestine taps has drastically increased as has violence related to the petroleum theft market in states such as Guanajuato, Puebla, and Veracruz.
Vanda Felbab-Brown, a senior research fellow at the Brookings Institution, pointed out in a recent interview for this note that the Andrés Manuel López Obrador (AMLO) administration has focused on economic nationalism, with Pemex playing a major role in the vision of the future of the country in lieu of a focus on new technologies such as solar and other energy alternatives. Thus, in 2019, the fight against oil theft appeared to be the sole focus of the new government. In April 2019, the government claimed oil theft was down by more than 90%. Unfortunately, as Felbab-Brown points out, the administration was forced to focus on a myriad of other activities—such as migration enforcement— due to pressure from the Trump administration. Further, the administration’s reliance on anticorruption measures has not generated the resources needed for serious state capacity or socio-economic redistribution reforms.
In roughly 2017—although earlier narcomantas from the CJNG in 2013 claim their arrival and intent to “cleanse” the state—the Cártel De Jalisco Nueva Generación (CJNG) began a coordinated campaign to wrest control of the state of Guanajuato, its pipelines, and major refinery at Salamanca from the CSRL. According to the Justice in Mexico Project, the CSRL had been a subsidiary of the CJNG and announced its independence under the leadership of El Marro in 2017. Guanajuato rapidly became one of the most violent states in Mexico as pitched battles between organized crime groups became common. For example, Table 1 below, is based on Armed Conflict Location & Event Data Project (ACLED) open source data collection, and demonstrates the high levels of violence in Guanajuato relative to other states in Mexico over the last year and half.
Table 1. Relative Violence in Guanajuato Compared to Other States. Source: Authors’ Elaboration using “Armed Conflict Location & Event Data Project (ACLED);” https://www.acleddata.com.
The leader of the CSRL, El Marro, proved adept at fighting the better resourced CJNG as he had with previous incursions of the Zetas and Caballeros Templarios. Both organizations proved tactically sophisticated, using Colombian papa bombs and improvised explosive devices (IEDs) primarily in the areas of major oil theft conflict.
While less discussed in Guanajuato, the Sinaloa Cartel has long operated there in low-profile fashion. Sinaloa operators were present in the state since the Ignacio “Nacho” Coronel era (pre-2010) when the CJNG was still part of the Sinaloa cartel operating as a paramilitary apparatus calling itself the Matazetas. The Sinaloa operators grew “lazy” and did not expand markets. Thus, they were unprepared when the battle-hardened CJNG entered the state in the 2010s. Once the CJNG scored victories across the country in new areas, the Sinaloa Cartel sponsored rivals to keep it weakened. El Marro sought support of theSinaloa faction led by Ismael “El Mayo” Zambada García after the extradition of Joaquín “El Chapo” Guzmán Loera in 2017 to the United States. That support did not materialize, as it didn’t meet Mayo Zambada’s strategic imperative, despite Sinaloa and the CSRL being mutual enemies of the CJNG and the CSRL’s violent business model.
Assessing the Aftermath of El Marro’s Capture
Interviews with security experts on Mexican organized crime point to multiple possibilities for the aftermath of the El Marro’s arrest in Guanajuato. Vanda Felbab-Brown suggested that the capture of El Marro is likely to lead to increased violence caused by both internal fighting between factions of the CSRL and attacks from the CJNG. Succession mechanisms can be built in she says but leaders are often reticent to do so due to the possibility of a “coup de group.” Other analysts agree with that assessment. Alejandro Hope, currently a columnist at El Universal, expects that, following the arrest of El Marro, there will be “significant fragmentation going forward. Extortion is likely to become democratized. Likewise for fuel theft.” Professor David Shirk agrees, stating “I think this is the beginning of the end for the CSRL, which will likely fragment, morph, or be obliterated by CJNG in El Marro’s absence.”
If the CJNG can establish a clear hegemony and “monopoly on violence” in Guanajuato, violence there may go down. For Felbab-Brown, “the best that can be hoped for is a quick CJNG victory” that might reduce violence but could embolden the CJNG vis-à-vis their proclivity to engage in violence against the state. That would trigger a stronger state reaction against the CJNG that could eventually lead to its fragmentation, though that is a medium to long term possibility.
It may also be possible that the CJNG victory or at least recognition of its dominance may establish a new more pacific equilibrium via agreements between organized crime groups. Falko Ernst, Senior Fellow of the International Crisis Group, sees reason to be optimistic in terms of short term violence reduction due to the ability of the CJNG to take advantage of El Marro’s arrest:
“The CJNG’s regional office has successfully gotten Marro’s lieutenants in line giving them the choice between lead or alignment. My sources say they accepted-for now. But this is no guarantee for long-term stability. The degree to which outside powers—national actors like the Sinaloans, or regional groups like the Nueva Familia and the Viagras—will attempt to strike deals with the lieutenants so as to throw a monkey wrench into the CJNG’s ambitions for regional hegemony.”
Thus, via agreements and a new criminal equilibrium, a tenuous short-term peace may be established in the wake of El Marro’s arrest.
None of the security experts interviewed for this Strategic Note thought that the El Marro arrest was due to or would be followed by a well-calibrated law enforcement and military response. Felbab-Brown sees little evidence of the AMLO Administration improving high value target (HVT) policy, including this particular arrest, by proactively mitigating the violence the HVT approach triggers in Mexico. She observed that no prepositioned troop or Guardia Nacional (GN) forces were moved into place before or immediately after the event. She argues such actions would give the state the capacity to control the criminal dynamic in the aftermath. The state is insufficiently resourced to address the narco-problem while “the AMLO administration has dropped the ball on police reform and the creation of the National Guard [NG] has damaged functional and well-performing federal police units, by tearing them apart to create NG units, often placing capable personnel into dysfunctional units.”
According to Hope, “Nothing has really changed on the institutional front: same police forces, same leadership, [and] same tactics. Case in point: in the week after the capture of El Marro, almost 70 people were killed in Guanajuato. Not much of [a] change.” According to Falko Ernst:
“There is no such thing as a sound strategy to reestablish state-based order in Guanajuato, or for that matter Mexico’s other high-conflict areas. So, for now it looks like a win for the CJNG – It’s come a step closer to building hegemony over Guanajuato. Lower violence in this context is however, already being sold as a win for the Lopez Obrador administration, which is desperate to sell good news vis-à-vis the 2021 elections, [whatever] they may be caused by and how shaky the ground upon which they’re built.”
All of the area specialists interviewed observed that federal and state cooperation in Guanajuato was particularly weak, with many citing political reasons or key individuals as having conflict with federal institutions.
For example, Alejandro Hope pointed out that Marro’s arrest was “mostly a federal job and they just threw a bone at the state government. As far as I know there is still a lot of mutual bad blood. In particular, the Army does not trust Attorney General Zamarripa at all.” Similarly, Shirk “doubt[s] that state forces in Guanajuato, the only state that voted against AMLO, are working particularly well with federal forces.”. Falko Ernst said that “whether or not a tentative, less violent order emerges depends to a far greater extent on whether the CJNG will be able to keep Marro’s lieutenants in line, and whether it will be able to effectively absorb ties to state actors built by Marro.” Ernst raises an important point here. The stability of CJNG takeover of the state of Guanajuato hinges not just on absorbing organized crime cells but on the ability to insert the CJNG into the same corruption networks to interface with the state.
In the short term, we assess that the CJNG will gain significantly from the arrest of El Marro which will likely lead to fragmentation of CSRL. The fragmentation could increase violence and encourage more rival encroachment. Over the long- term, the Sinaloa Cartel or regional players like Nueva Familia and Los Viagras are likely to play spoiler by contacting local lieutenants and attempting to weaken CJNG power in the state. We also see the possibility of Sinaloa coordinating rivals to counter the CJNG with an umbrella group of rivals to keep the CJNG occupied in its territories rather than potentially encroaching into Sinaloa territories. This type of “balancing” behavior was predicted by Small Wars Journal-El Centro Fellow Irina Chindea and has been borne out numerous times in the Mexican organized crime context with umbrella groups like the Carteles Unidos working to counter the CJNG.
Another long-term ramification of El Marro’s arrest is the potential for the AMLO administration to target the CJNG for its violent confrontations with the state and its more aggressive predatory business model. The perception that it is gaining hegemony in more areas of Mexico such as Guanajuato could speed up that process. With more rapid targeting, a critical tipping point could be achieved allowing the state to fragment the CJNG into smaller pieces so it cannot threaten the state. However, that in and of itself could increase violence, which politically would be detrimental to AMLO. Thus, the long-term story of Marro’s arrest could be part of the broader story of the rise and perceived strength of the CJNG. This also points to a potential future cycle of an ever-increasing prevalence of criminal violence. The only way to end that vicious cycle will be to increase Mexican state capacity. The AMLO administration will need to raise revenues, reform police and the judiciary, and establish a better national security and law enforcement strategy to address organized crime violence in Mexico. The need for better coordination between the Guardia Nacional (GN)and military forces, as well as local and state forces in Guanajuato to control the criminal dynamic is also amplified in the aftermath of the El Marro’s high value arrest.
The present reality on the streets in Mexico signifies that AMLO’s internal security policies are increasingly kneecapped. The effects of the COVID-19 pandemic along with a deepening recession amplify the ongoing criminal insurgencies. Guanajuato is at the epicenter of these conflicts. As a consequence, Mexico is further losing political capacity. Additional economic and personnel resources simply do not exist with the trade, oil, remittance, and tourism sectors now devastated. The government is losing the competitive extractive revenue battle with the cartels and street gangs. Cartel and gang taxes take precedence over public taxation for many of its citizens. The incremental ‘hollowing out’ of the Mexican state and its evident fragility suggest that federal authorities will likely remain reactive bystanders in the raging conflict between the CRSL, the CJNG, and the other criminal organizations that have been—or are now being—drawn into it.
