Nemesio Oseguera, also known as 'El Mencho', the leader of the Jalisco New Generation Cartel (CJNG), was killed in a firefight with soldiers in Tapalpa, Jalisco, after being injured and later dying while on his way to Mexico City. His death triggered widespread violence across 20 states, with cartel members blocking roads and setting vehicles and business establishments ablaze. The government's response to this surge in violence was swift, deploying 10,000 soldiers to restore order.

The violence escalated during the raid to capture Oseguera, resulting in the deaths of at least 27 security personnel, 46 suspected criminals, and one civilian. In addition, the assault on a prison during this chaos prompted the escape of at least 23 inmates, highlighting the pervasive reach of cartel influence in the region. The U.S. had previously placed a $15 million bounty on Oseguera's head, reflecting the seriousness of his criminal activities and the threat posed by CJNG.

While peace has somewhat returned, with calm reported in the aftermath of the violence, many businesses remained closed due to safety concerns. Residents had initially sought refuge, and tourists were advised to stay in their hotels during the chaos. The Mexican government's decision to mobilize soldiers indicates the severity of the situation and the ongoing struggle against cartel violence in the country, illustrating the deep-rooted challenges faced by law enforcement in combating organized crime.
