Billings residents seeking a warm escape in Mexico have encountered unexpected turmoil as cartel violence disrupts travel plans, particularly in Puerto Vallarta.

The unrest ignited after Mexican military forces killed Nemesio Rubén Oseguera Cervantes, known as "El Mencho," the leader of the Jalisco New Generation Cartel (CJNG), during an operation in Tapalpa, Jalisco. In retaliation, cartel members launched widespread violence, including burning vehicles and blocking highways, affecting multiple states, notably Jalisco.

In response, the U.S. Embassy in Mexico issued a security alert advising American citizens in affected areas, including Puerto Vallarta, to shelter in place. Travelers were urged to avoid crowds, stay alert, and keep family informed of their whereabouts.
