Nemesio Rubén Oseguera Cervantes, better known as “El Mencho,” has been formally wanted by Mexican federal authorities since late 2011, so he had been a wanted man for about 14–15 years up to his death in February 2026.

Quick Scoop: How long has El Mencho been wanted?

  • Mexico’s Office of the Attorney General issued an arrest warrant for El Mencho on 27 September 2011 for organized crime and illegal firearms.
  • From that date until his killing by Mexican security forces in February 2026, he spent roughly a decade and a half as a top fugitive.
  • Over those years, he rose to become Mexico’s most-wanted cartel leader and one of the most-wanted criminals in the United States.

Key timeline

  1. 2011 – First major Mexican warrant
    • 27 September 2011: Mexican authorities issue an arrest warrant and offer a reward for information leading to his capture.
  1. 2014 – U.S. criminal charges
    • March 2014: A U.S. federal court in Washington, D.C., indicts him on drug‑trafficking and related charges, making him a high‑priority international target.
  1. 2015–2024 – Most‑wanted status solidifies
    • 2015: Mexico launches “Operation Jalisco,” a major campaign aimed in part at capturing El Mencho as head of the Jalisco New Generation Cartel (CJNG).
 * Over the following years, both Mexico and the U.S. sharply increase rewards; by the mid‑2020s, he is described as the country’s most‑wanted cartel boss, with U.S. and Mexican rewards totaling up to about 15 million dollars and 300 million pesos.
  1. 2026 – End of the manhunt
    • February 2026: Mexican forces locate and kill El Mencho in a high‑risk operation, formally ending a pursuit that had lasted since at least 2011.

Forum-style take

In online discussions, people often point out that El Mencho managed to evade capture for well over a decade, despite being at the very top of Mexico’s and the U.S.’s wanted lists, which fed a lot of speculation about protection networks, corruption, and his low‑profile lifestyle compared with flashier cartel bosses.

So, if you’re asking “how long has El Mencho been wanted,” the straightforward answer is: he was officially wanted by Mexican authorities from September 2011 until his death in February 2026 — about 14–15 years, and internationally since at least 2014.
