WASHINGTON — A Santa Clara man who co-founded one of Mexico’s most powerful and violent drug cartels pleaded guilty on Tuesday in the U.S. to a federal narcotics conspiracy charge. Erick Valencia Salazar formed the Jalisco New Generation Cartel with Nemesio Oseguera Cervantes, the drug lord known as “El Mencho” who was killed by the Mexican army in February.

Valencia Salazar 49, faces a mandatory-minimum prison sentence of 10 years and a maximum of life in prison after pleading guilty in Washington, D.C., to one count of conspiring to distribute cocaine for U.S. importation. Chief Judge James Boasberg is scheduled to sentence Salazar on July 31.

Valencia Salazar was a member of the Milenio Cartel before he and Oseguera Cervantes founded the Jalisco cartel, which is known by its Spanish-language acronym CJNG. Hundreds of CJNG members reported to Valencia Salazar, whose duties included recruitment and obtaining information about the cartel’s rivals, prosecutors said. Valencia Salazar, also known as “El 85,” formed his own cartel, La Nueva Plaza, after parting ways with “El Mencho,” who led the CJNG until his death.

A. Tysen Duva, the assistant attorney general in charge of the Justice Department’s criminal division, said the CJNG has inflicted “immeasurable damage” on the U.S.

A grand jury indicted Valencia Salazar on the conspiracy charge in 2018. In February 2025, Mexican authorities sent him to the U.S. as part of an initial group of 29 drug lords.
