Nemesio “El Mencho” Oseguera Cervantes, leader of the notorious Jalisco New Generation Cartel (CJNG), died Sunday following a targeted military strike in Mexico’s Jalisco state.
The cartel boss ranked among the most sought-after fugitives in both Mexican and American law enforcement circles. Washington had placed a $15 million bounty on information that would lead to his apprehension.
Defence Secretary Ricardo Trevilla revealed that military forces located El Mencho by surveilling one of his romantic companions to a hideout in Tapalpa. Intelligence provided by someone close to one of the kingpin’s partners enabled authorities to execute a swift tactical response.
The raid triggered an immediate armed response from cartel enforcers. The confrontation eventually centered on a cabin facility situated in a forested region, where El Mencho sustained critical injuries along with two security personnel.
Military helicopters evacuated all three individuals toward the capital. General Trevilla verified that none survived the transport.
The assault claimed eight cartel operatives. Authorities confiscated grenades, munitions, armored trucks, and multiple rocket launching systems from the location.
The CJNG represents one of Mexico’s most dangerous criminal enterprises. The organization specializes in smuggling massive volumes of fentanyl, methamphetamine, and cocaine across the U.S. border and received foreign terrorist organization designation from the Trump administration in February 2025.
News of El Mencho’s demise triggered widespread cartel reprisals throughout a minimum of 20 states. Operatives established roadblocks using spikes and nails, hijacked public buses and civilian vehicles, then torched them on major thoroughfares.
Jalisco state witnessed the deaths of at least 25 National Guard personnel in six distinct cartel assaults. Additional casualties included a corrections officer, an investigator from the state prosecutor’s office, and 30 cartel members during the ensuing chaos.
Military Deployment Across the Nation
Authorities mobilized roughly 9,500 military personnel total, with an extra 2,500 soldiers arriving in western regions Monday. Officials reported at least 70 arrests across seven states.
Security Minister Omar Garcia Harfuch stated that authorities remained “closely monitoring for any kind of reaction or restructuring within the cartel that could lead to violence.”
Tourist Zones Affected by Violence
Footage verified by BBC Verify captured tourists observing from resort pools as military helicopters circled overhead and smoke billowed from structures in Puerto Vallarta. Multiple carriers canceled flights to the destination.
The U.S. State Department advised American citizens in impacted regions to remain indoors. Its round-the-clock emergency line fielded hundreds of inquiries.
By Monday, President Claudia Sheinbaum announced that authorities had dismantled all 250-plus barricades spanning 20 states. She commended the military forces and characterized Mexico as “at peace” and “calm.”
The White House acknowledged providing intelligence assistance for the mission and commended Mexican armed forces for neutralizing El Mencho.
The operation and subsequent violence produced a combined death toll of at least 73 individuals, encompassing security personnel, suspected cartel operatives, and civilians.
