For more than a decade, the name Nemesio Oseguera Cervantes, better known as El Mencho, dominated headlines in Mexico and the United States. Authorities described him as one of the most powerful and dangerous drug traffickers in the world. As the alleged leader of the Jalisco New Generation Cartel (CJNG), he built a fast-growing criminal empire that challenged rival cartels and openly confronted security forces.
From his early days in rural Michoacán to becoming one of the most wanted men globally, El Mencho’s journey reflects the transformation of Mexico’s organised crime landscape. His leadership turned CJNG into a highly militarized and aggressive organisation. Here is a detailed look at his life, family, wealth, criminal record and how he rose to power.
Who was El Mencho?
El Mencho was a Mexican cartel leader born in Aguililla, Michoacán. Authorities accused him of leading CJNG’s global drug trafficking network, moving methamphetamine, cocaine, heroin and fentanyl into the United States and other markets.
US officials once placed a reward of up to $15 million for information leading to his capture. They described him as strategic, violent and highly secretive. Despite multiple operations targeting him, he managed to evade arrest for years. His ability to survive crackdowns helped build his myth and strengthened his reputation inside criminal circles.
El Mencho Net Worth
An exact estimate of the late drug lord’s net worth is not known. However, in 2019, the DEA had indicated that it might exceed $1 billion. An archived Univision report indicates DEA agent Kyle Mori, who was engaged in capturing the elusive crime boss say “I would say he has at least $500 million, and it could even exceed $1 billion.”
El Mencho Wife
El Mencho married Rosalinda González Valencia in 1996. Her family, known as Los Cuinis, allegedly managed the financial arm of CJNG. Authorities accused her of overseeing shell companies and businesses linked to cartel funds. Reports indicate the couple legally separated in 2018. She later faced financial crime charges in Mexico.

His children also drew law enforcement attention. El Menchito served as second-in-command before his arrest and conviction in the United States. Jessica Johana was jailed for managing business fronts tied to cartel operations. Laisha has faced allegations of involvement in cartel-linked violence.
El Mencho Siblings
Authorities identified Antonio Oseguera Cervantes as one of his key relatives with alleged operational links. Investigators claimed some siblings helped strengthen CJNG’s internal structure.
El Mencho Age
Born on July 17, 1966, in Aguililla, Michoacán, El Mencho was 57 years old at the time of his reported death.
El Mencho: How He Died?
According to Mexican security officials, armed forces targeted him during a coordinated operation in Tapalpa, Jalisco. Troops reportedly faced armed resistance before fatally wounding him. Authorities deployed air support and tactical units during the mission.
El Mencho Real Name
El Mencho’s real name was Nemesio Oseguera Cervantes. Authorities used this name in official indictments and international arrest warrants.
El Mencho History
El Mencho grew up in the Tierra Caliente region of Michoacán. In the 1990s, he entered drug trafficking. A US court sentenced him in 1994 for conspiracy to distribute heroin. After serving time, he returned to Mexico and briefly worked as a local police officer in Jalisco before rejoining organised crime.
He joined the Milenio Cartel and later aligned with figures connected to the Sinaloa Cartel. After internal splits in 2010, his faction evolved into CJNG. Under his command, CJNG expanded aggressively across Mexico, fighting groups like the Zetas and the Knights Templar.
Rise of CJNG & War With Rivals
After the fragmentation of the Milenio Cartel, El Mencho consolidated loyal factions and declared war on rival groups, including former allies in the Sinaloa Cartel to form CJNG around 2009-2011. This marked another turning point in Mexico’s criminal landscape. His leadership style combined business efficiency with ruthless violence.
The CJNG adopted paramilitary tactics rarely seen at such a scale in organised crime, deploying armoured vehicles, heavy weapons, rocket launchers, and uniformed gunmen. The cartel frequently released propaganda videos showing convoys of fighters to project power and intimidate opponents.
El Mencho: What Crimes Was He Involved in?
As head of CJNG, El Mencho allegedly directed the group’s criminal operations across Jalisco, Colima, Michoacán, Guanajuato, Veracruz and Chiapas, making the cartel a major force in trafficking cocaine, methamphetamine, heroin and fentanyl.
The cartel also engaged in oil theft, human trafficking, extortion and migrant smuggling. Officials believe El Mencho ordered the assassination of Mexican politicians, including the killing of Jalisco tourism secretary Jesus Gallegos Alvarez in 2013, and the murder of Congressman Gabriel Gomez Michel in 2014.
El Mencho Allies & Enemies
A crucial ally for CJNG was Los Cuinis, led by Abigael Gonzalez Valencia, the brother of El Mencho’s wife. Los Cuinis operated across Latin America to launder cartel profits. However, after US indictments in 2015, most family members were arrested, and their financial networks were absorbed by CJNG.
CJNG’s early enemies included the Zetas and the Knights Templar. As the cartel grew, its main rival became the Sinaloa Cartel, battling for control of trafficking routes, especially near the Guatemala border. Other conflicts include rivalries with the Northeast Cartel (CDN), Old School Zetas, and Santa Rosa de Lima Cartel. In Michoacán, CJNG clashes with Carteles Unidos have displaced thousands of residents and drawn federal intervention.
CJNG also made temporary alliances in regions such as Baja California and Ciudad Juárez, but failed to establish strongholds in some areas.
What Does El Mencho Mean?
“El Mencho” reportedly translates loosely to “the one with bad taste.” Criminal aliases often enhance identity and fear within cartel culture.
What Happened to El Mencho in Mexico?
Mexican authorities intensified operations against him over the years. Security forces frequently targeted CJNG strongholds. His reported death marks one of the biggest blows to the cartel’s leadership structure.
What is CJNG?
The Jalisco New Generation Cartel emerged around 2010. It became one of Mexico’s most powerful and violent criminal groups. Authorities described it as highly militarised, technologically advanced and globally connected in drug trafficking.

How Did He Became Mexican Drug Lord?
