On Sunday, Nemesio Ruben Oseguera Cervantes, also known as "El Mencho," was killed in a shootout in Jalisco, Mexico, as the military attempted to apprehend him. "El Mencho" was the leader of the Jalisco New Generation Cartel, a prominent criminal network involved in trafficking fentanyl, methamphetamine, and cocaine to the United States.
Following the incident, cartel members instigated violence across Mexico, including road blockages and the burning of vehicles. President Claudia Sheinbaum has called for calm, and authorities have since cleared most of the over 250 cartel roadblocks across 20 states.
The United States government provided intelligence support to the operation targeting "El Mencho." The U.S. Department of State had previously offered a $15 million reward for information leading to his capture.

The Jalisco New Generation Cartel, operational since around 2009, is recognized as one of Mexico's most powerful criminal organizations. It was designated a "Foreign Terrorist Organization" by the U.S. administration in February 2025. The cartel is known for its aggressive tactics, including attacks on military forces and the use of drones to launch explosives.
In 2020, the cartel attempted an assassination using grenades and high-powered rifles against the then head of the Mexico City police force, who is now the federal security secretary.
President Sheinbaum has expressed criticism of the strategy of targeting cartel leaders, noting that such actions can lead to increased violence as cartels fragment. Despite her popularity, security remains a significant concern, and she faces pressure to demonstrate effective measures against drug trafficking.
