What to know about cartel leader killing and violence in Mexico

What to know about cartel leader killing and violence in Mexico

El Mencho’s Fall: A Shifting Landscape for Mexican Cartels and US Security

The death of Nemesio Oseguera Cervantes, “El Mencho,” leader of the Jalisco New Generation Cartel (CJNG), marks a pivotal moment in Mexico’s ongoing struggle with drug trafficking. While hailed as a significant victory by the Mexican government and welcomed by the US, the long-term implications are complex and potentially volatile. The immediate aftermath has been characterized by widespread violence, with reports of roadblocks and arson across 20 Mexican states and a scramble for safety among tourists, including New Zealand citizens.

The Rise and Reign of ‘El Mencho’

For decades, Oseguera Cervantes, 59, steadily climbed the ranks of Mexico’s criminal underworld. His CJNG, founded around 2009, rapidly became Mexico’s fastest-growing cartel, specializing in trafficking cocaine, methamphetamines, fentanyl, and migrants to the United States. Unlike some predecessors, the CJNG embraced brazen tactics, including attacks on Mexican security forces – even downing a military helicopter in 2015 – and attempts on high-profile officials.

The cartel distinguished itself through aggressive recruitment, innovative online outreach, and diversification of revenue streams, including fuel theft, extortion, and timeshare fraud. “El Mencho” controlled the organization like a dictator, according to former DEA Chief of International Operations, Mike Vigil.

Immediate Fallout: Violence and Disruption

The operation to capture Oseguera Cervantes, conducted by the Mexican army and National Guard, resulted in the deaths of eight cartel members alongside “El Mencho” and two of his bodyguards. The seizure of rocket launchers capable of downing aircraft underscores the cartel’s firepower. The immediate response was a wave of violence intended to demonstrate the CJNG’s continued power and disrupt government control. Schools were cancelled in several states, and residents in Guadalajara locked themselves in their homes.

A Strategic Win for Mexico and the US

The timing of this operation is significant, given ongoing pressure from the US to address the flow of drugs into the country. The Trump administration had previously designated the CJNG as a foreign terrorist organization and threatened tariffs if Mexico didn’t demonstrate sufficient progress. The US State Department had offered a $15 million reward for information leading to Oseguera Cervantes’ arrest. Intelligence cooperation between the two countries played a key role in the successful operation.

US Deputy Secretary of State Christopher Landau applauded the operation, and Mike Vigil stated that Mexico had sent “a strong message to Donald Trump’s administration that they are fighting aggressively, and effectively.”

The Looming Power Vacuum and Potential Scenarios

The death of “El Mencho” creates a significant power vacuum within the CJNG. The cartel has a presence in at least 21 of Mexico’s 32 states and operates extensively in the US, making its leadership crucial. Several scenarios are possible:

  • Internal Struggle: Relatives of Oseguera Cervantes may attempt to seize control, potentially prolonging the violence seen in the immediate aftermath.
  • Fragmentation: The cartel could splinter into factions, weakening its overall power but potentially increasing localized conflicts.
  • Sinaloa Cartel Opportunity: The CJNG’s weakened state could allow the Sinaloa Cartel, currently navigating its own internal power struggles, to regain ground.

Security analyst David Saucedo warns of the potential for indiscriminate violence, even “narcoterrorism attacks” reminiscent of Colombia in the 1990s, if the cartel feels cornered.

The Fentanyl Factor: A Growing Threat

The CJNG has become a major player in the fentanyl trade, a highly potent synthetic opioid driving the overdose crisis in the United States. Disrupting the cartel’s leadership could impact the supply chain, but experts caution that other organizations are poised to fill the void. The fentanyl crisis remains a critical concern for both Mexico and the US, regardless of who controls the CJNG.
