Mexico City: Nemesio Oseguera Cervantes, widely known as El Mencho and leader of the powerful Jalisco New Generation Cartel, was killed during a Mexican military operation in the western state of Jalisco, according to government and security sources. His death marks one of the most significant blows to organized crime in Mexico in recent years.
The operation took place near the town of Tapalpa on Saturday. Security forces moved in to capture the cartel boss, who had long been one of the most wanted drug traffickers in the world. Reports indicate that he died from injuries sustained during the raid after cartel gunmen engaged troops.
Mexican authorities were supported by United States intelligence, which helped locate the target. Washington had placed a reward of 15 million dollars for information leading to his capture and had been pressing Mexico to curb fentanyl trafficking and other drug flows linked to the cartel.
In the hours following news of his death, violence erupted in several areas believed to be under cartel influence. Armed groups set vehicles and businesses on fire, blocked highways and clashed with security forces.
Authorities deployed additional troops and police to restore order and remove roadblocks. Some airports suspended flights and schools were temporarily closed as a precaution.
El Mencho, a former police officer, built the Jalisco New Generation Cartel into one of the most powerful criminal organizations in the world. The group has been linked to trafficking fentanyl, methamphetamine and cocaine to international markets, as well as widespread violence inside Mexico.
President Claudia Sheinbaum praised the operation and said it demonstrated strong cooperation between Mexico and the United States in combating organized crime. United States officials also welcomed the development, describing it as a major step against drug trafficking networks.
Security analysts warn that the killing could trigger a struggle for control within the cartel and lead to further violence in the short term. While the death of its leader weakens the organization, experts say criminal networks often adapt quickly, making continued vigilance essential.
Authorities remain on high alert as they work to prevent retaliation and stabilize affected regions.
