AI-Generated Disinformation Amplifies Violence and Fear After Cartel Leader's Death in Mexico
After Mexican armed forces killed Cártel de Jalisco Nueva Generación leader Nemesio Oseguera on February 22, 2026, cartel members reportedly used AI-generated images and videos to amplify disinformation about the scale of resulting violence, according to news reports. The synthetic media claimed buildings were burning and the Guadalajara airport was under cartel control, and spread thousands of times on social media, while Mexican security officials opened an investigation into the campaign.
What happened
On February 22, 2026, Mexican armed forces killed Nemesio Oseguera, leader of the Cártel de Jalisco Nueva Generación. In the following hours, social media filled with news, images and videos documenting disturbances caused by members of organized crime aligned with the cartel, including roadblocks, burned buses and attacks on businesses.
Circulating alongside these reports were exaggerated versions and AI-generated images and videos showing buildings and planes in flames and the Guadalajara airport under cartel control. These synthetic media were reportedly spread by cartel members themselves.
Reported impact
The Observatorio de Medios Digitales del Tec de Monterrey estimated that between 200 and 500 pieces of misinformation or unverified information were shared in the first 48 hours after the operation, with approximately 20 to 40 reaching 50,000 reactions, 100,000 views and at least 10,000 shares.
Jane Esberg of the University of Pennsylvania stated the objective was to make cartel actions appear more frightening than they actually were and to demonstrate that the Mexican government has no control over the country. The disinformation also made it difficult for authorities to establish the scale of violence and determine what they faced.
Index analysis
Cárteles have long used social media for multiple purposes, including attacking rival groups and promoting community efforts. However, the rapid spread of AI-generated synthetic media after Oseguera's death represented a new capability in this strategy.
Governance controls
Omar García Harfuch, Mexico's Secretary of Security, stated on the Monday following the operation that many disinformation accounts had already been identified. He said further investigation would determine which accounts had direct relations with organized crime groups and which only spread falsehoods.
