Juan Carlos Valencia González, also known as “El 03,” “R3” and “El Pelón,” is a Mexican-American criminal figure identified by U.S. authorities as the successor to Nemesio Rubén Oseguera Cervantes, known as “El Mencho,” at the head of the Jalisco New Generation Cartel (CJNG).
Valencia González was born in Santa Ana, California, on September 12, 1984. His U.S. birthplace has made him an American citizen, while he also has Mexican nationality. He is the stepson of El Mencho and the biological son of Armando Valencia Cornelio, a founder of the former Milenio Cartel.
His rise to the top of the CJNG followed the death of El Mencho during a Mexican military operation in February 2026. In August 2026, the U.S. Department of Justice stated that, according to court filings, Valencia González assumed the role of CJNG’s top leader after Oseguera’s death. The National Counterterrorism Center had also identified him as the organization's new leader.
The CJNG has been designated by the United States as a Foreign Terrorist Organization. U.S. authorities accuse the organization of large-scale international drug trafficking and other criminal activities. These are allegations concerning the organization and its members and should be distinguished from individual convictions.
Valencia González himself faces federal charges in the United States. According to the U.S. Department of Justice, an indictment accuses him of conspiracy to manufacture and distribute cocaine and methamphetamine for unlawful importation into the United States, as well as firearms-related offenses. The department stated that, if convicted, he could face two consecutive life sentences.
The U.S. government significantly increased the financial incentive for information leading to his arrest or conviction in August 2026. The Department of State announced a reward of up to US$25 million, making Valencia González one of the most heavily rewarded fugitives in the U.S. government's narcotics-rewards program. The official reward poster identifies him as “Juan Carlos Valencia González, a/k/a ‘Pelón.’”
His American citizenship has also attracted unusual attention. Because Valencia González was born in California, U.S. authorities face additional legal and procedural considerations when dealing with him as an American citizen abroad. Reporting by The Wall Street Journal described his citizenship as a complicating factor for U.S. intelligence and law-enforcement efforts.
There is some uncertainty surrounding the exact structure of the CJNG after El Mencho's death. U.S. authorities have identified Valencia González as the organization's top leader, but organized-crime researchers have cautioned that the cartel may operate through several powerful factions rather than through a completely centralized hierarchy. InSight Crime, for example, reported that several senior figures retained significant influence after El Mencho's death.
This distinction is important when describing Valencia González's current position. The U.S. government officially identifies him as the CJNG's top leader, while independent analysis indicates that the organization's post-El Mencho structure may be more complex than a single-person chain of command.
As of October 2026, Valencia González remains wanted by U.S. authorities and faces federal allegations that have not resulted in a final conviction. His case represents a notable development in the evolution of the CJNG following the death of its longtime leader and demonstrates the increasingly international dimensions of investigations into Mexican organized crime.
