Nemesio Oseguera Cervantes, better known as El Mencho, was one of Mexico’s most notorious drug lords until his death in a military raid on February 22, 2026, at the age of 59. As the founder and leader of the Jalisco New Generation Cartel (CJNG), he built a criminal empire marked by extreme violence, drug trafficking, and corruption that spanned continents. His personal life, however, remained shrouded in secrecy, with his family often entangled in the web of his operations. El Mencho’s marriage to Rosalinda González Valencia, a key figure from a criminal dynasty herself, produced three children who have variously been drawn into the spotlight through arrests, allegations, and the shadow of their father’s legacy.
The kids—two daughters and one son—were born in different eras of El Mencho’s life, reflecting his journey from a small-town avocado farmer to a fugitive kingpin. Raised amid wealth and danger, they have faced scrutiny from U.S. and Mexican authorities, with some accused of aiding the CJNG’s financial and operational arms. While El Mencho evaded capture for years, his offspring have not been as fortunate, highlighting the generational toll of cartel involvement.

The Daughters: Jessica and Laisha
Jessica Johanna Oseguera González, known by the alias La Negra, is the eldest child, born on July 23, 1986, in San Francisco, California, making her 39 years old as of early 2026. She spent part of her childhood in the U.S. before her father’s deportation separated the family.
Jessica has maintained she distanced herself from El Mencho since she was 11, but U.S. authorities charged her with financial crimes linked to the CJNG, including dealings with blacklisted businesses. Arrested in Washington, D.C., in February 2020 while attending her brother’s court hearing, she pleaded guilty in March 2021 and served a 2.5-year sentence, being released in April 2022. As a mother of two, Jessica expressed remorse during her trial, emphasizing her desire to reunite with her children in Guadalajara.

The youngest daughter, Laisha Michelle Oseguera González, was born on April 4, 2001, in Mexico, and is currently 24 years old. Less publicized than her siblings, Laisha has nonetheless been implicated in cartel activities. Mexican authorities have accused her of orchestrating a high-profile kidnapping in 2018 as retaliation for her mother’s arrest, showcasing the family’s use of violence to protect their interests.
Born during a period when El Mencho was consolidating power in the CJNG, Laisha represents the next generation potentially inheriting the burdens of her parents’ criminal world, though details of her current whereabouts remain sparse amid ongoing investigations.

The Son: Rubén ‘El Menchito’ Oseguera González
Rubén Oseguera González, commonly called El Menchito—a diminutive of his father’s moniker—is the only son, born on February 14, 1990, in San Francisco, and now 36 years old. Dual U.S.-Mexican citizen, he was seen as the heir apparent to the CJNG, allegedly serving as its second-in-command before his capture. Arrested in Mexico in 2015 after multiple failed attempts, Rubén was extradited to the U.S. in 2020, where he faced charges of drug trafficking, conspiracy, and firearms offenses. His 2024 trial in Washington, D.C., featured testimony from former cartel members, including relatives, underscoring the fractures within these organizations.

Convicted in September 2024, Rubén faces a potential life sentence, with sentencing scheduled for January 2025, though delays have occurred due to his father’s recent death. His case exemplifies the challenges for “narco juniors”—the millennial offspring of boomer-era cartel bosses—who often lack the street-hardened loyalty of their parents’ generation. With El Mencho gone, Rubén’s imprisonment leaves a void in the family dynamic, potentially shifting power within the CJNG to other factions.
