The CJNG After El Mencho: Succession, Fragmentation, and What Comes Next
The possible removal of Nemesio Oseguera Cervantes, widely known as El Mencho, has raised a question that reaches far beyond the fate of one criminal leader: what happens to the Jalisco New Generation Cartel when the person who built and coordinated its modern power is no longer at the center?
There is no simple answer. A leadership change could produce fragmentation, internal conflict, adaptation, or a combination of all three. The consequences would likely be felt not only inside the organization, but also across Mexico’s security landscape and international drug-trafficking routes.
How El Mencho Built the CJNG
El Mencho’s rise was not based on inherited power. His early life was marked by limited opportunities in Michoacán, followed by time in the United States, contact with criminal activity, and deportation. After returning to Mexico, he spent time in local policing—an experience that gave him insight into how authorities worked, where their weaknesses lay, and how criminal groups could avoid detection.
He later joined the Milenio Cartel. When that organization fractured, he recognized an opportunity in the resulting chaos. From that break emerged the CJNG, which expanded from a stronghold in Jalisco into a national and international criminal network.
The organization’s growth was rapid and unusually aggressive. It challenged established rivals, pursued territory and trafficking routes, and developed a reputation for disciplined operations and calculated brutality. Unlike more publicity-seeking criminal figures, El Mencho generally maintained a lower public profile. His influence came less from celebrity than from control, organization, and fear.
A Criminal Network Larger Than One Man
The CJNG is often described as a single cartel, but its structure is better understood as a network of cells operating across different regions. These groups may have local autonomy while remaining connected to a broader chain of command.
That structure has helped the organization expand and survive pressure. Its activities have been associated with the trafficking of synthetic drugs, including methamphetamine and fentanyl, as well as extortion, kidnapping, fuel theft, money laundering, and other illicit enterprises. Diversification provides multiple revenue streams, making the organization less vulnerable when one operation or route is disrupted.
The network also has an international dimension. Its trafficking relationships and financial systems extend beyond Mexico, linking regional operations to markets and logistics networks in North America and other parts of the world. That reach means a leadership crisis could affect more than local territorial disputes; it could disrupt routes, alliances, finances, and supply chains.
Why a Leadership Crisis Could Become Dangerous
The question surrounding El Mencho’s status has circulated amid contradictory reports and a lack of definitive public clarity. In criminal environments, uncertainty itself can become a weapon. Rumors may be used to test reactions, conceal movements, weaken rivals, or create confusion among members and authorities.
Whether the reports ultimately prove accurate or not, a perceived threat to the leader’s position can create pressure inside the organization. Members begin watching for signs of weakness. Regional commanders may reassess their loyalties. Rivals may test boundaries. Authorities may intensify efforts to exploit the disruption.
If a leader were captured or otherwise removed, the immediate result would not necessarily be the collapse of the cartel. In many cases, the removal of a dominant figure creates a period of instability in which competing factions fight to inherit the organization’s assets and influence.
The Succession Problem
A successor would need more than a family connection or a reputation for violence. The next leader would have to manage regional commanders, protect trafficking and financial systems, maintain internal discipline, and deter outside rivals at the same time.
Several types of figures could compete for influence. Close relatives might offer continuity and symbolic legitimacy. Trusted lieutenants could claim that their operational experience makes them the safest choice. Regional commanders might rely on their control of territory, personnel, and local alliances. Security and financial chiefs could also become important power brokers because they control information, weapons, money, and communications.
These interests do not automatically align. A family-based succession could preserve loyalty but lack operational authority. A regional commander might control the ground but face resistance from other territories. A military-oriented faction could impose order quickly while increasing the risk of internal coercion and conflict.
For that reason, the first phase after a leadership change might involve a temporary power-sharing arrangement rather than a single undisputed replacement. Such an arrangement could preserve the organization for a time, but it would also be vulnerable to betrayal and competing ambitions.
Three Possible Futures for the CJNG
Fragmentation
The most volatile outcome would be a split into competing factions. Regional groups could keep their own territories, routes, and revenue while claiming to represent the broader organization. Fragmentation would not necessarily make the threat disappear. Smaller factions can be more difficult to track and may fight more aggressively to secure their positions.
Centralized Succession
A trusted successor could consolidate power and preserve much of the existing structure. This would require rapid control over communications, finances, security, and the loyalty of regional leaders. If successful, the cartel could emerge weakened but still coherent.
Quiet Decentralization
The organization might also become less visibly centralized. Rather than replacing one famous leader with another, regional operators could gain more autonomy while maintaining business relationships and shared interests. This could reduce the cartel’s public profile without ending its operations, potentially making it more difficult for authorities to identify a single center of gravity.
What Rivals and Authorities Would Watch
Any sign of weakness could invite challenges from rival cartels and local armed groups. Competitors may seek to seize territory, redirect trafficking routes, recruit defectors, or take control of profitable local economies. The most contested areas could see increased violence as factions try to demonstrate that the organization remains capable of retaliation.
Authorities would likely focus on communication networks, financial movements, regional alliances, and changes in the behavior of commanders. A transition can create vulnerabilities, but it can also make the criminal landscape more complicated. A fragmented network may be less predictable and harder to dismantle than a hierarchy with a clearly identifiable leader.
Consequences for Mexico and Beyond
The effects of a CJNG succession crisis would likely vary by region. Some communities could experience open conflict between factions, while others might see a quieter redistribution of influence. Either way, civilians could face extortion, displacement, disrupted commerce, and heightened insecurity.
Internationally, changes in the organization could affect drug-trafficking routes, border pressure, financial flows, and relationships with criminal partners. The removal of a central coordinator might temporarily interrupt some operations, but decentralized groups could also adapt by using new routes and more discreet financial methods.
The most important point is that the arrest or removal of a leader does not by itself dismantle the system that supports organized crime. Networks of money, personnel, weapons, logistics, corruption, and local influence can survive a change at the top.
A Turning Point, Not an Automatic Ending
The future of the CJNG would depend on whether its internal structure is strong enough to absorb the loss of its central figure. El Mencho’s importance lies not only in his public identity, but also in the authority and coordination attributed to his leadership.
If that authority cannot be transferred, the organization could fracture and enter a prolonged period of conflict. If it can be transferred, the cartel may adapt into a quieter or more decentralized network. In either case, the consequences would extend beyond one person.
The central lesson is that organized crime is sustained by systems, not just personalities. Removing a leader can create a meaningful disruption, but it does not guarantee the end of the organization. The decisive period would come afterward, as successors, rivals, authorities, and communities respond to the new balance of power.
