The leader of the Jalisco New Generation (CJNG) cartel, Nemesio Oseguera Cervantes, died in custody on February 22, shortly after he was captured by the Mexican authorities. The operation, which came amid renewed US demands for “tangible results” against fentanyl trafficking, appears to have relied on American intelligence support.
This is the most significant intervention against the cartels since the capture of former drug lord Joaquín “El Chapo” Guzmán in 2016. The CJNG is one of the strongest criminal organisations in Mexico and, alongside the Sinaloa cartel, sits at the centre of US claims about fentanyl production and trafficking.
The killing of Oseguera Cervantes, who is better known as “El Mencho”, may have enabled Mexico’s authorities to secure a political win with Washington. But the operation should not be seen as a victory. What often comes next when the Mexican state removes a high-profile cartel figure like El Mencho is an extended period of violence and instability inside the country.
