El Mencho’s Successor: The Rise of Juan Carlos Valencia González

The death of Nemesio Rubén Oseguera Cervantes, known as “El Mencho,” leader of the Jalisco New Generation Cartel (CJNG), has triggered a wave of violence across Mexico and raised questions about the future of the powerful criminal organization. As authorities grapple with the aftermath, a key contender to take control of the $20 billion empire has emerged: Juan Carlos Valencia González, El Mencho’s stepson.

The Fall of El Mencho and the Cartel’s Response

El Mencho was killed on Sunday, February 23, 2026, during a military operation in western Mexico [CBS News]. The cartel responded with widespread chaos, blocking roads at over 250 points in 20 Mexican states, and turning Guadalajara into a “ghost town” [ABC7NY]. At least 14 people were killed, including seven National Guard troops [AP News].

Juan Carlos Valencia González: The Frontrunner?

Juan Carlos Valencia González, also known as El Pelon, Tricky Tres, and O3, is widely considered the “de-facto second in command” of the CJNG. He is a dual citizen of the United States and Mexico, born in Santa Ana, Orange County, California, in 1984 [CBS News]. His mother, Rosalinda “La Jefa” González Valencia, played a significant role in the cartel’s financial operations and may support her son’s bid for leadership.

A History of Criminal Activity

While details of Juan Carlos’ early life remain scarce, his involvement with the cartel came to light during a Drug Enforcement Administration (DEA) probe in 2020. He was identified as being responsible for the production and distribution of “tons of narcotics” and linked to violent crimes dating back to 2007 [CBS News]. He was also identified in footage showing the armed wing of the Jalisco Cartel in July 2020.

US Indictment and Bounty

In October 2020, the US government issued a federal indictment against Juan Carlos, charging him with conspiracy to distribute a controlled substance and using a firearm during a narcotics transaction. A $5 million reward was offered for information leading to his arrest or conviction [CBS News]. DEA Administrator Anne Milgram stated the reward underscored the US government’s commitment to pursuing those causing the most harm in American communities.

Challenges to Succession

Despite being a leading candidate, some security analysts question Juan Carlos’ influence within the cartel, particularly among other commanders [ABC7NY]. El Mencho’s older brother, Antonio Oseguera Cervantes, is in US custody, and his son, Ruben Oseguera-Gonzalez, is serving a life sentence plus 30 years for his crimes.

Impact on the FIFA World Cup

The violence following El Mencho’s death poses a threat to the FIFA World Cup, which is scheduled to be held in Mexico, the United States, and Canada later this year. Guadalajara is slated to host several matches, including Mexico’s game against Korea on June 18, and clashes between Colombia and Uruguay and Spain on June 23 and 26, respectively [ABC7NY].

Accusations and Retaliation

OnlyFans influencer María Julissa has been accused of providing information to authorities that led to El Mencho’s capture, though she denies these claims. She has since received threats from alleged cartel members, including a banner warning her for “biting the hand that feeds you” [ABC7NY].
