El Mencho, aka Nemesio Rubén Oseguera Cervantes, was a notorious figure in Mexico’s criminal underworld. For decades, he led the Jalisco New Generation Cartel (CJNG), a group that grew into one of the most powerful drug cartels in the world. His story is not just about crime but also about how a man from a poor farming family rose to become a figure who shaped Mexico’s drug war.
Mencho’s life was full of contradictions. On one side, he was seen as a ruthless leader who ordered violent attacks against rivals and even government forces. On the other side, he lived a modest life compared to other drug lords, often staying away from flashy displays of wealth. His death in February 2026 marked the end of an era, but his influence continues to affect Mexico and beyond.

Early Life and Beginnings
El Mencho was born in Aguililla, Michoacán, Mexico, on July 17, 1966. His family worked as avocado farmers, and his childhood was marked by poverty. He left school after the fifth grade, which was common in rural areas where children often had to help their families earn a living.
At the age of 14, he began working as a guard in marijuana fields. This early exposure to the drug trade gave him a first look at the world that would later define his life. Unlike many who dream of escaping poverty through education or regular jobs, Mencho’s path was shaped by the environment around him—one where crime and survival often went hand in hand.
Migration to the United States
In the 1980s, Mencho crossed into the United States illegally, settling in California. He used several fake names to hide his identity. His time in America was marked by arrests and jail sentences. In 1986 and 1989, he was arrested in San Francisco for drug-related charges. Later, in 1992, he was caught in Sacramento for selling heroin.
He spent time in prison in Texas before being deported back to Mexico. These years in the U.S. showed his determination to stay in the drug trade despite repeated setbacks. They also gave him experience in dealing with law enforcement, something that would later help him avoid capture for decades in Mexico.
Entry into Organized Crime
After returning to Mexico, El first worked as a police officer. This gave him knowledge of law enforcement systems, which he later used to outsmart authorities. Soon, he joined the Milenio Cartel, a group that was active in drug trafficking.
His marriage to Rosalinda González Valencia, who came from a family deeply involved in cartel activities, strengthened his position. Through this marriage, he built strong ties with the González Valencia clan, also known as “Los Cuinis,” who were key players in organized crime.

Rise Through the Milenio Cartel
The Milenio Cartel faced internal problems after its leaders were arrested. El saw this as an opportunity. He formed a group called Los Mata Zetas (The Zeta Killers), which fought against the rival Zetas cartel. This group later became the foundation of the CJNG.
By using violence and smart strategies, Mencho managed to take control of territories in western Mexico. Under his leadership, CJNG grew rapidly, becoming one of the most feared cartels in the country. His rise was not just about power but also about building a network that could challenge older cartels like the Sinaloa Cartel.
Leadership of CJNG
When Mencho took full control of the Jalisco New Generation Cartel (CJNG), he turned it into one of the fastest-growing criminal groups in Mexico. Unlike older cartels that focused mainly on cocaine, CJNG expanded into methamphetamine and heroin. His cartel also spread its influence beyond Mexico, reaching into the United States, Europe, Asia, and even Africa.
El Mencho was known for using both violence and strategy. His men carried out attacks against rival cartels and even government forces. In one shocking incident, CJNG fighters shot down a military helicopter in 2015. This showed the cartel’s strength and willingness to fight openly against the state. Under his leadership, CJNG became known not only for drug trafficking but also for extortion, kidnapping, and arms smuggling.
Family and Personal Relationships
El Mencho’s personal life was closely tied to his cartel activities. He married Rosalinda González Valencia in 1996. Rosalinda came from the González Valencia family, also called “Los Cuinis,” who were deeply involved in organized crime. This marriage gave El strong family connections that helped him build CJNG.
He had three children: Jessica Johanna, Laisha Michelle, and Rubén Oseguera González, better known as “El Menchito.” His son was considered his second-in-command before being arrested and extradited to the United States. There were also rumours of a relationship with María Julissa, a social media personality, though these claims were never fully proven. Mencho’s brothers—Juan, Miguel, Antonio, Marín, and Abraham—were also linked to cartel activities.
Legal Troubles and Global Manhunt
Mencho was one of the world’s most wanted men. Both Mexico and the United States issued arrest warrants against him. The U.S. government placed him under the Kingpin Act, which froze his assets and banned American citizens from doing business with him. He was also listed as a Specially Designated Global Terrorist.
Authorities offered huge rewards for his capture. The U.S. government announced a $15 million bounty, while Mexico offered 300 million pesos. Despite this, El managed to avoid capture for years. He was known for living in remote areas, moving constantly, and using loyal followers to protect him. His ability to stay hidden made him a symbol of how difficult it was to fight cartels in Mexico.
Death and Final Operation
On 22 February 2026, Mencho’s story came to an end. Mexican special forces, with help from U.S. intelligence, carried out a raid in Tapalpa, Jalisco. During the operation, El Mencho was killed by gunshot wounds in a confrontation with soldiers.
