Information about Nemesio Oseguera Cervantes' family life is scarce due to the secretive nature of his operations and the high-profile status he holds. He is known to be married, though details about his spouse or children are not widely published, likely for safety reasons.

After three years he was released from prison on parole and deported to Mexico at the age of 30. In Mexico, he joined the local police forces of Cabo Corrientes and Tomatlán in the state of Jalisco. After some time he left the police and joined organized crime as a full-time member of the Milenio Cartel.
To strengthen his relationship with the Milenio Cartel, El Mencho married one of the clan leader's sisters, Rosalinda González Valencia. It was in this criminal group where El Mencho would become a leading figure in organized crime.
Net Worth and Salary

His wealth is largely derived from drug trafficking, money laundering, and other criminal enterprises linked to the CJNG. Reports suggest that the cartel has profit margins that place it among the most lucrative in the world, making Oseguera one of the wealthiest figures in organized crime. However, due to the constant threat of law enforcement action, estimating an exact salary is challenging, as income can fluctuate based on operational status and law enforcement pressures.
In 2019 Kyle Mori, the head of the DEA team tasked with locating El Mencho, stated in an interview with Univision that he believed El Mencho had a net worth of at least $500 million and he could also be worth over $1 billion.
Career, Business and Investments
Nemesio Oseguera Cervantes' career began in the world of drug trafficking, where he quickly rose through the ranks due to his strategic mindset and ruthless nature. The Jalisco New Generation Cartel, under his leadership, has expanded its operations beyond traditional drug trafficking to include extortion, kidnapping, and illegal mining among other criminal activities. Oseguera has been credited with diversifying the cartel’s revenue streams and increasing its influence both domestically and internationally.
With substantial resources at his disposal, he has reportedly invested in various legitimate businesses to help launder money. Although specific details about these businesses are deliberately obfuscated due to their illegal nature, it is widely believed that he has interests in several industries, including agriculture and real estate.
In 1989, El Mencho was arrested again in San Francisco for selling narcotics. He was deported to Mexico several months later, but re-entered the U.S. and resettled in San Francisco. In September 1992, he was arrested again, this time on federal drug charges in Sacramento, California.
According to court records, El Mencho and his brother Abraham were at a San Francisco bar known as Imperial to carry out a heroin deal: five ounces for US$9,500. Abraham was in charge of the transaction, while El Mencho acted as a lookout.
El Mencho was 26 years old at that time, much younger than Abraham, but was savvy enough to recognize that the transaction was a set-up by the police. He told his brother that the men to whom they gave the heroin handed over perfectly stacked dollar bills instead of loose ones.
Through a wiretap conversation, the police overheard El Mencho warning his brother to never do business with them again since they were undercover cops.
Social Network
Nemesio Oseguera Cervantes avoids traditional social media and public engagement platforms due to the risk of exposure and capture. While he does not maintain a presence on popular social networks like Instagram or Twitter, his cartel utilizes various channels to communicate and promote its agenda. Information about him is often circulated through underground forums and channels among those affected by or involved in cartel activities.
His first name is cited as "Rubén" and/or "Nemesio". He has alternative aliases like "Nemecio", "Rubén Acerguera Cervantes", "Lorenzo Mendoza", and "Nemesio Oseguera Ramos". Some sources state that his birth-given name was Rubén but that he changed it to Nemesio in memory of his godfather.
He is widely known by his alias "El Mencho", a nickname that derives from the phonetic derivation of Nemesio. Another nickname is "The Lord of the Roosters", said to be derived from his love for cockfighting.
Education
Little is known about Nemesio Oseguera Cervantes' educational background. It is speculated that he has minimal formal education, which is often the case with many individuals involved in the drug trade. His skills appear to be a combination of street smarts and knowledge acquired through experience in the criminal underworld. The lack of records or public knowledge regarding his education reflects the general secrecy surrounding his life, further complicating the accuracy of any biographical details.
Born into poverty in Mexico, El Mencho grew avocados and dropped out of primary school before immigrating illegally to the U.S. in the 1980s. After being arrested several times, he was deported to Mexico in the early 1990s and worked for the Milenio Cartel. He eventually climbed to the top of the criminal organization and founded the CJNG after several of his bosses were arrested or killed.
