A fierce power struggle grips the Jalisco New Generation Cartel (CJNG) following the death of its leader, Nemesio Rubén Oseguera Cervantes, known as El Mencho. Mexican security forces killed him during an operation in Jalisco over the weekend, unleashing chaos across the country.01

Cartel Leadership Vacuum Emerges

El Mencho’s demise leaves the CJNG without a clear successor. His son, Rubén Oseguera González, alias El Menchito, remains imprisoned in the United States. The cartel’s other son and stepson lack the necessary experience to lead the organization.27

La Jefa Steps into the Spotlight

Rosalinda González Valencia, 63, known as La Jefa or “the boss,” stands as a potential contender. El Mencho’s ex-wife, with whom he shares three children, separated from him in 2018. She brings decades of expertise in money laundering operations, channeling cartel funds through shell companies and hospitality businesses.63

González Valencia hails from a criminal lineage as the niece of El Maradona, founder of the Milenio Cartel, which splintered to form the CJNG. Authorities currently do not know her whereabouts.

La Negra’s Role in the Mix

Jessica Johanna Oseguera González, El Mencho’s daughter nicknamed La Negra, has also faced legal troubles for money laundering tied to the cartel. Both mother and daughter maintained low profiles after brief incarcerations.45

Speculation grows that a mother-daughter alliance between La Jefa and La Negra could position them as Mexico’s most influential narco queens, leveraging their financial acumen to steer the cartel.

Challenges to Female Leadership

However, experts question whether women can command the militarized CJNG. Mexico City-based security consultant David Saucedo states, “It’s likely that one of four or five top commanders will emerge as the next leader.”43

Founded in 2009, the CJNG gained notoriety for brutal tactics, including drone strikes with explosives and roadside mines during turf battles against rivals and security forces.
