The death of one of the world's most wanted drug traffickers, Nemesio Oseguera Cervantes, known as "El Mencho", has shocked Mexico and left behind a power vacuum at the head of the infamous Jalisco Nueva Generacion (CJNG) cartel.
But while the 59-year-old leader was killed by federal forces in the state of Jalisco, his multi-billion dollar empire remains intact and eyes are now turning to his wife and family.
"La Jefa" at the center of the storm
In the violent, male-dominated world of Mexican cartels, she is known as “La Jefa” – The Boss. Rosalinda González Valencia, 63, married Oseguera in 1996 and is considered by authorities to be a key part of the cartel’s financial structure.
According to the Mexican government, her arrest in 2021 was “a significant blow to the financial structure of organized crime.” She was sentenced to five years in prison for money laundering and released last year for good behavior. Her whereabouts have remained unknown since then.
Former US drug war officials have described her as a "narco queen", noting that she had access to her husband's information and financial network.
Although in the world of cartels, inheritance usually passes to a male figure, some analysts do not rule out the possibility that she could try to take over, a scenario reminiscent of the series Griselda or the film Traffic.
Children involved in the murderous network
“El Mencho”’s family has long been a target of US authorities. His daughter, Jessica Johanna Oseguera González, known as “La Negra,” was arrested in the US in 2020 and sentenced to 30 months in prison for money laundering. According to the US Department of Justice, she managed several sanctioned businesses, including a sushi company and a tequila brand.
Meanwhile, his son, Rubén Oseguera González, known as “El Menchito,” was extradited to the US and sentenced to life in prison, as well as the confiscation of over $6 billion. He was considered the Cartel’s number two and responsible for trafficking tens of tons of cocaine.
A global cartel with a brutal reputation
Under the leadership of “El Mencho,” the CJNG became one of the most powerful and violent criminal organizations in Mexico. It became known for open attacks on security forces, including the downing of a military helicopter in 2015, and assassinations of high-ranking officials.
The cartel has extended its network across five continents, trafficking hundreds of tons of cocaine, methamphetamine and fentanyl to the US and other international markets.
Following the killing of its leader, Mexico was gripped by a wave of violence, with burning vehicles, blocked airports and armed clashes in several states. Mexican President Claudia Sheinbaum said the operation against the cartel was part of a broader strategy to restore state control over criminal organizations.
Who will take the lead?
Security experts believe that the succession of power in the cartel usually passes to a close family figure to avoid infighting. One of the most mentioned names is “El Mencho”’s stepfather, Juan Carlos Valencia González.
However, if the organization's senior leaders do not reach an agreement, there is a risk of an internal power struggle, which could further escalate the violence in the country.
The CJNG remains a pyramid-structured organization, with “El Mencho” exercising unquestioned command. With his departure, the future of one of the most powerful drug empires in the world remains uncertain, but one thing is clear: his dynasty has not yet fallen.
