Day 37: O3 Collective Council Structure Hardens; Operativo Enjambre Institutionalizes Anti-Corruption Framework

We will deploy up to 100,000 security personnel across Guadalajara, Mexico City, and Monterrey for the 2026 FIFA World Cup. Guadalajara is a world-class city and Mexico will demonstrate that security and hospitality go hand in hand. The cartel succession crisis in Jalisco will not define our country on the world stage — we have the operational capacity and the political will to ensure a safe tournament.

El Mencho built the most powerful criminal organization in the Western Hemisphere from a rural Michoacán village. His February 2026 death leaves a power vacuum with no clear successor.

As El Mencho's stepson and commander of CJNG's paramilitary Grupo Élite, O3 commands the cartel's most militarized unit and has U.S. citizenship — creating both an organizational advantage and unique legal exposure.

Arrested March 11, 2026 in Mexicali, Baja California — charged with homicide, terrorist acts, and armed robbery. El Doble R was widely considered the top succession candidate after El Mencho. His capture eliminates the most formidable internal consolidator from the succession race, narrowing the field to O3 and El Jardinero. (Sources: La Silla Rota, El Financiero)

Treasury-designated CJNG commander with a $5 million U.S. bounty. El Jardinero manages significant CJNG territorial operations and is among the senior figures who will determine the cartel's post-Mencho direction.

Released early from a five-year money laundering sentence in early 2025 for 'good conduct,' sparking controversy. Rosalinda's González Valencia family connections to Los Cuinis made her CJNG's key financial architect. She remains free and under scrutiny.

The man CJNG tried to kill in June 2020 ended up overseeing the operation that killed El Mencho in February 2026. As Security Secretary and former intelligence director, García Harfuch personifies Mexico's decade-long escalation against CJNG.

Led the institutional military planning behind the Tapalpa operation. SEDENA under Trevilla has deepened intelligence-sharing with U.S. NORTHCOM and DEA while maintaining operational command authority over cartel interdiction missions on Mexican soil.

Sheinbaum inherited Mexico's cartel crisis from AMLO and has navigated between maintaining her predecessor's social-investment approach and cooperating more closely with U.S. security demands following CJNG's FTO designation and the February 2026 El Mencho operation.

DEA has designated CJNG as one of the highest-priority Consolidated Priority Organization Targets (CPOTs). Operation Python (2020) and the sustained intelligence campaign against El Mencho represent the DEA's most intensive sustained targeting effort against a single cartel.

Secretary Rubio officially designated CJNG as a Foreign Terrorist Organization on February 20, 2025, implementing the Trump executive order and marking a major escalation in U.S. legal treatment of Mexican cartels. The designation enabled new prosecution tools against material supporters.

El Mencho's son and former heir apparent was extradited to the U.S. in 2020 and sentenced to life plus 30 years in March 2025, with a $6 billion forfeiture order. His imprisonment sealed CJNG's succession crisis before his father's death.

CSRL leader whose August 2020 arrest handed CJNG a decisive advantage in Guanajuato. El Marro became a social-media-savvy cartel boss who posted videos defending his gang's role in defending communities from CJNG, but ultimately could not sustain military resistance without state protection.

Originally a community self-defense group, Los Viagras evolved into a criminal enterprise competing with CJNG over Michoacán's avocado and lime extortion rackets. Their knowledge of local terrain gives them a 'profound advantage' in Tierra Caliente despite CJNG's superior firepower.

Journalists and rights defenders documenting CJNG violence face severe retaliation. Mexico has remained one of the world's most dangerous countries for journalists for over a decade, with CJNG-linked threats and killings documented across Jalisco, Colima, Michoacán, and Veracruz.

Identified by U.S. intelligence agencies alongside O3, El Jardinero, and El Sapo as a fourth potential CJNG succession candidate. Tío Lako has managed logistics and corridor operations in northern and central Mexico for CJNG and has emerged as a figure of elevated interest as other succession candidates have been arrested or killed. His profile rose sharply following El Doble R's March 11 arrest and El Tuli's February 22 killing. No active U.S. reward announced as of March 29, 2026.

InSight Crime and the International Crisis Group have provided the most sustained independent analysis of CJNG's structure, tactics, and succession dynamics. Their assessments consistently warn that decapitation strategies risk fragmentation that produces more violence, not less.

Killed by Mexican special forces in El Grullo, Jalisco, in a parallel operation on Feb 22 — the same day as El Mencho. El Tuli served as CJNG's top financial/logistics architect. He had offered 20,000-peso bounties per soldier killed in retaliation. $965,000 USD and 7.2M pesos seized at time of death.

U.S. Treasury-designated CJNG boss of the Puerto Vallarta Plaza and key Chinese precursor chemical acquisition coordinator. Former CJNG operative testimony pointed to El Sapo as a possible successor. Some Mexican media reports suggest he may have been killed in the Feb 22 operation — status officially unconfirmed. (Source: Latin Times)

O3 has reportedly been named the new CJNG leader following El Mencho's death, per an anonymous cartel source and consistent with U.S. NCTC assessment of him as 'de facto second-in-command.' Born in Santa Ana, California (September 12, 1984), O3 is an American citizen — creating legal complications for U.S. targeting operations. As commander of Grupo Élite, CJNG's most militarized paramilitary unit, he commands the cartel's greatest concentrated firepower. His path to consolidation is clearer with El Doble R arrested and El Tuli dead — but El Jardinero's regional power remains a rival center. Mexican authorities have not officially confirmed the succession. [Sources: InSight Crime, IBTimes UK, U.S. State Department assessment]

The arrest of 'El Pepe' in Tlajomulco de Zúñiga represents the closure of a critical intelligence gap. This individual transported El Mencho's companion to the Tapalpa hideout — the link in the chain that ultimately led to the elimination of the most wanted criminal in Mexico's history. Mexico's security forces are systematically dismantling the entire network that protected El Mencho for decades.

El CJNG es una organización criminal que opera en todo el país. Despite the historic elimination of El Mencho and the sustained post-Tapalpa pressure campaign, the cartel's national operational footprint remains intact. Mexico's security forces will continue systematic dismantlement of CJNG's network — but citizens and businesses across all 27 affected states should remain vigilant.

No había condiciones para resguardar los inmuebles donde hallaron la narconómina de 'El Mencho.' The properties where El Mencho's financial ledgers and payroll records were discovered could not be adequately secured immediately after the February 22 operation. The FGR is working to preserve the evidentiary value of all materials found. Critics and opposition lawmakers have demanded a formal investigation into potential evidence tampering at the sites.
