(Worthy News) – Major Mexican drug lord Nemesio Oseguera, known as “El Mencho,” was killed Sunday during a military operation in Jalisco state, Mexico’s Defense Department announced, delivering one of the most significant blows to organized crime in recent years.
Oseguera, 59, led the powerful Cártel de Jalisco Nueva Generación (CJNG), a global trafficking network and a major supplier of fentanyl to the United States. The U.S. government had placed a $15 million bounty on his capture.
Mexican authorities said troops targeted Oseguera in Tapalpa, Jalisco, as part of coordinated efforts with U.S. intelligence support. During the operation, he was wounded in a shootout and later died while being transported to Mexico City. Four additional suspects were killed at the scene, and two others were detained. Authorities reported seizing armored vehicles and heavy weaponry, including rocket launchers capable of downing aircraft.
Three members of Mexico’s armed forces were injured and are receiving medical treatment.
The operation sparked widespread cartel retaliation across Jalisco and other regions. Authorities reported burning vehicles, highway blockades, and attacks on infrastructure, including damage to approximately 20 branches of Banco del Bienestar. At least 21 highways were blocked, though some have since reopened.
Violence was also reported in the tourist city of Puerto Vallarta, where images showed thick smoke rising over the skyline.
U.S. Deputy Secretary of State Christopher Landau called the development “a great development for Mexico, the U.S., Latin America, and the world,” adding that cartel violence would not deter ongoing security cooperation.
The U.S. Embassy in Mexico issued shelter-in-place advisories for several states, including Jalisco, Tamaulipas, Michoacán, Guerrero, and Nuevo León, urging American citizens to remain indoors until further notice.
Jalisco Governor Pablo Lemus Navarro confirmed that the state remains under heightened security alert as National Guard and Army reinforcements deploy to restore order.
The operation comes amid sustained pressure from President Donald Trump’s administration on Mexican President Claudia Sheinbaum to intensify action against drug cartels and curb fentanyl trafficking into the United States. Officials described Sunday’s strike as a major step in bilateral efforts to dismantle cartel leadership and disrupt transnational criminal networks.
