After the killing of Nemesio Oseguera Cervantes, the head of the Jalisco Cartel, his stepson Juan Carlos Valencia González has emerged as a key contender to take over the $20 billion criminal enterprise. The 41-year-old dual U.S. and Mexican citizen was born in Santa Ana, California and is known by aliases like 'El Pelon' and 'Tricky Tres'. He has been indicted by the U.S. government for drug trafficking and violent crimes since 2007, with a $5 million bounty on his head.

Why it matters

The Jalisco Cartel is one of Mexico's most powerful and violent criminal organizations, responsible for a wave of narco-terrorism and blockades across the country following the killing of 'El Mencho'. Whomever takes over the cartel will wield immense power and influence, potentially leading to further bloodshed and instability in the region.

The details

Juan Carlos Valencia González is the stepson of Nemesio Oseguera Cervantes, the former leader of the Jalisco Cartel who was killed in a raid by Mexican security forces. Valencia González, also known as 'El Pelon', 'Tricky Tres' and 'O3', is a dual U.S. and Mexican citizen born in 1984 in Santa Ana, California. He has been indicted by the U.S. government for drug trafficking and violent crimes since 2007, with a $5 million bounty on his head. Analysts suggest his mother, Rosalinda 'La Jefa' González Valencia, could also take over the cartel, but most expect her to back her son's bid for leadership.

  • On Sunday, February 23, 2026, Nemesio Oseguera Cervantes, also known as 'El Mencho', was killed in a raid by Mexican security forces.
  • In October 2020, the U.S. government returned a federal indictment charging Juan Carlos Valencia González with conspiracy to distribute a controlled substance and using a firearm during a narcotics transaction.

“This didn't seem to be just an operation to capture 'El Mencho,' but to exterminate him, to use lethal force to bring him down. In the criminal underworld, such actions are not simply overlooked. The reaction is what we're seeing now: narco-terrorism, blockades, and fires in grocery stores across Mexico.”
