Nemesio Rubén Oseguera Cervantes, better known by his alias “El Mencho,” was one of the most notorious figures in the world of organized crime. As the founder and leader of the Cartel Jalisco Nueva Generación (CJNG), he transformed a regional drug trafficking group into a global powerhouse responsible for widespread violence, drug smuggling, and economic disruption. His death on February 22, 2026, during a Mexican military operation has sent shockwaves through Mexico and beyond, sparking immediate retaliatory violence and raising questions about the future of cartel dynamics. This comprehensive article explores his early life, ascent to power, criminal empire, impacts on Mexico and the United States, the circumstances of his death, and the current trends surrounding this pivotal event.
Early Life :- From Rural Poverty to U.S. Deportation
Born on July 17, 1966, in Aguililla, a small rural municipality in the western Mexican state of Michoacán, Nemesio Oseguera Cervantes grew up in extreme poverty. Raised in a family of agricultural workers, he labored in avocado fields from a young age and dropped out of primary school after the fifth grade to support his household. Aguililla, located in the Tierra Caliente region, was already a hotbed for drug cultivation, particularly marijuana and opium poppies, which influenced many locals to enter the narcotics trade.
In his late teens, Oseguera Cervantes illegally immigrated to the United States, settling in California where he had family ties. There, he became involved in small-scale drug dealing. His first confirmed brush with the law came in 1986 when he was arrested in San Francisco for possession of heroin. He served time in U.S. prisons and was deported back to Mexico in the early 1990s. Undeterred, he returned to the U.S. illegally and was arrested again in 1994 for methamphetamine distribution, leading to another prison stint and deportation in 1997.
Some reports suggest Oseguera Cervantes briefly served as a police officer in Mexico before fully entering the criminal world, but this remains unconfirmed and is often described as a rumor. (Disclaimer: This detail is based on unverified accounts and should be treated with caution; no official records substantiate it.) His experiences in the U.S. prison system likely forged connections with criminal networks that would prove instrumental in his later career.

Rise to Power :- From Milenio Cartel Enforcer to CJNG Founder
Upon his final deportation in 1997, Oseguera Cervantes returned to Michoacán and joined the Milenio Cartel, a mid-level organization involved in methamphetamine production and cocaine trafficking from South America. Starting as a low-level operator, he quickly rose through the ranks due to his ruthlessness and strategic acumen. By the early 2000s, he was a key enforcer, overseeing security and hit squads.
The turning point came in 2009-2010 when the Milenio Cartel fractured due to internal disputes and arrests of its leaders. Oseguera Cervantes, along with allies like Abigael González Valencia, seized the opportunity to form a new group: the Cartel Jalisco Nueva Generación (CJNG). Initially positioning itself as a “new generation” of traffickers fighting against rivals like Los Zetas, CJNG rapidly expanded through brutal tactics, including public executions and attacks on authorities.
Under El Mencho’s leadership, CJNG diversified beyond drugs. They pioneered large-scale fuel theft (known as “huachicoleo”) from Pemex pipelines, extortion rackets, and human smuggling. By 2015, CJNG had downed a military helicopter with a rocket-propelled grenade, killing nine soldiers, in a bold escalation that demonstrated their military-grade capabilities. Oseguera Cervantes evaded capture for years, reportedly using plastic surgery, body doubles, and a network of safe houses in remote areas.

Leadership and Criminal Activities of CJNG
As CJNG’s undisputed leader, El Mencho built an empire with thousands of members operating in at least 21 Mexican states and 36 countries worldwide. The cartel specialized in synthetic drugs like methamphetamine and fentanyl, sourcing precursors from China and smuggling finished products through Pacific ports like Manzanillo. CJNG’s violence was unprecedented: mass graves, beheadings, and attacks on civilians became hallmarks.
El Mencho’s family played key roles—his son, Rubén “El Menchito” Oseguera González, handled U.S. operations until his 2015 arrest and extradition, where he received a life sentence in 2025. His daughter, Jessica Johanna, was arrested in the U.S. in 2020 on money laundering charges. This familial structure helped maintain loyalty but also made CJNG vulnerable to targeted enforcement.

Impact on Mexico :- A Legacy of Violence and Economic Disruption
El Mencho’s CJNG profoundly destabilized Mexico. The cartel waged wars against rivals like the Sinaloa Cartel, leading to record homicide rates in states like Jalisco, Michoacán, and Guanajuato. Their control over ports and infrastructure fueled corruption, with bribes infiltrating police, military, and politicians. Fuel theft alone cost Mexico billions annually.
CJNG’s tactics included recruiting via social media, arming local cells with advanced weaponry, and terrorizing communities through extortion and forced displacement. In Guadalajara, a 2026 FIFA World Cup host city, the cartel’s presence raised security concerns, especially post-death violence that shut down the city. Experts warn his death could fragment CJNG, sparking internal power struggles and alliances with other groups, potentially increasing short-term violence.
Impact on the United States :- Fentanyl Crisis and Cross-Border Threats
CJNG under El Mencho became a primary driver of the U.S. opioid epidemic, flooding the market with fentanyl that killed tens of thousands annually. The DEA estimated CJNG’s presence in all 50 states, with hubs in cities like Los Angeles, Chicago, and Atlanta. U.S. authorities designated CJNG a foreign terrorist organization and offered a $15 million bounty on El Mencho.
His operations exacerbated border tensions, with potential migration surges from instability. The 2026 operation to kill him involved U.S. intelligence from a new FBI-ICE task force, signaling enhanced bilateral cooperation under Presidents Trump and Sheinbaum. While disrupting CJNG might reduce drug flows long-term, experts predict temporary chaos.
How He Was Killed :- The February 2026 Operation
On February 22, 2026, Mexican special forces, supported by U.S. intelligence, raided a safe house in Tapalpa, Jalisco, aiming to capture El Mencho. Tracked via a romantic partner’s “trusted man,” he was wounded in a firefight and died en route to Mexico City. The operation killed over 70 people, including 25 soldiers and cartel members.
Retaliation was swift: CJNG gunmen torched vehicles, blocked highways, and attacked infrastructure across 20 states, paralyzing cities like Guadalajara. Schools closed, flights canceled, and tourists were stranded. This violence, the most widespread since 2019’s Culiacán battle, highlighted CJNG’s reach.
