Rubén Oseguera González, commonly referred to by his alias El Menchito, is an American convicted drug lord and former high-ranking member of the Jalisco New Generation Cartel (CJNG), a criminal group based in Jalisco. He is the son of Nemesio Oseguera Cervantes, Mexico's formerly most-wanted man at the time of his death in 2026. Under his father, he allegedly worked as the CJNG's second-in-command and managed international drug trafficking operations. Oseguera González was first arrested in January 2014 in Jalisco, but was released in October for lack of evidence and re-arrested immediately as he walked out of prison. He was then released again in December after a judge considered the evidence against him as insufficient. In June 2015, Oseguera González was arrested again, released a month later, and re-arrested as his release order was made official. His legal case has highlighted the growing tensions and deficiencies between prosecutors and judges in Mexico.
