The world of Mexican cartels is full of mystery, power, and high-stakes drama. Few figures have captured as much attention as Nemesio Oseguera Cervantes, better known as El Mencho, the elusive leader of the Jalisco New Generation Cartel (CJNG). Recently, shocking details emerged about how authorities finally tracked him down — through a romantic partner. As of February 2026, reports indicate El Mencho met a violent end in a military operation on February 22, 2026, in Tapalpa, Jalisco, after surveillance of his girlfriend helped pinpoint his location.
This post dives into the intriguing yet shadowy story of El Mencho girlfriend, his past relationships, and what it all means in the cartel world. Let’s break it down.

Who Was El Mencho? A Quick Background
El Mencho rose from humble beginnings in rural Michoacán to become one of Mexico’s most feared drug lords. Leading the CJNG, he oversaw massive operations in fentanyl, methamphetamine, and other drugs, making the cartel a global powerhouse. For years, he evaded capture with a $15 million U.S. bounty on his head.
His personal life stayed extremely private — until recent events pulled back the curtain. Authorities long suspected he had separated from his long-time wife around 2018, opening the door to new relationships.
The Long-Time Wife: Rosalinda González Valencia
Before any talk of a girlfriend, El Mencho’s most known partner was Rosalinda González Valencia, often called “La Jefa” (The Boss). They married in 1996, a union that blended his operational muscle with her family’s financial networks from the Los Cuinis group.
- Key facts about their relationship:
- Married in 1996
- Three children: Rubén (“El Menchito”), Jessica Johana (“La Negra”), and Laisha
- Rosalinda allegedly handled money laundering and finances for CJNG
- Arrested multiple times (notably in 2018 and 2021) on charges like organized crime and money laundering
- Released after serving time, with the couple reportedly separated since around 2018
Rosalinda came from a powerful Michoacán family tied to early cartel structures. Their marriage was strategic, strengthening alliances. Even after separation, she remained a key figure in discussions about the cartel’s future.
The Reported Girlfriend: Who Is She?
Recent reports from Mexican authorities point to a woman linked to El Mencho in his final days. Defense officials revealed that tracking a romantic partner — and a trusted associate who escorted her — led forces to a secret meeting in Tapalpa, Jalisco, on February 20, 2026.
- Some leaks and reports name Guadalupe Moreno Carrillo as the likely partner:
- Mentioned in 2022 Guacamaya Leaks documents as part of his inner circle post-Rosalinda’s arrests
- Relationship reportedly began after 2021
- Authorities followed her movements to locate the hideout
- U.S. intelligence reportedly helped confirm details
Officials didn’t always name her publicly during briefings, referring to “one of his romantic partners.” The rendezvous reportedly involved her visiting a compound, after which forces moved in. This “love nest” detail added a dramatic, almost cinematic twist to the operation that ended El Mencho’s run.
Note: Details remain murky due to the secretive nature of these circles — confirmations come from official statements and leaks, but full verification is tough.
