Jalisco New Generation Cartel

Rosalinda González Valencia is a Mexican businesswoman and convicted money launderer of the Jalisco New Generation Cartel (CJNG), a criminal group based in Jalisco. She has also been known by her alias "La Jefa". She was married to El Mencho, once one of Mexico's most-wanted criminals.

Nemesio Rubén Oseguera Cervantes, commonly referred to by his alias "El Mencho", was a Mexican drug lord and head of the Jalisco New Generation Cartel (CJNG), an organized crime group based in Jalisco. He was the most wanted person in Mexico and one of the most wanted in the United States at the time of his death. The U.S. government and the Mexican government were offering rewards of up to US$15 million and MXN$300 million, respectively, for information leading to his arrest.

The Jalisco New Generation Cartel, also known as CJNG, is a Mexican criminal syndicate based in Jalisco founded and headed by Nemesio Oseguera Cervantes, commonly known as El Mencho, until he was killed by the Mexican Army in 2026. The cartel has been characterized by extreme violence and public relations campaigns. Though the CJNG is known for diversifying into various criminal rackets, drug trafficking remains its most profitable activity. The cartel has been noted for cannibalizing some victims during the training of new sicarios or members, as well as using drones and rocket-propelled grenades to attack enemies.

On 22 February 2026, the Mexican Armed Forces conducted an operation which killed El Mencho, the leader of the Jalisco New Generation Cartel (CJNG), and six others in Tapalpa, Jalisco, Mexico. The operation sparked clashes in the area, resulting in shootouts, explosions and multiple vehicles and stores being set on fire throughout the state and much of the rest of the country. The clashes have resulted in dozens of casualties for both the National Guard and cartel members, as well as at least one civilian death.

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.
