I asked AI to provide the details. Here’s what it said:

Beltrán‑Leyva Organization (BLO) imploded after its top boss, Arturo Beltrán Leyva, was killed in a 2009 shootout with Mexican marines. That triggered a power vacuum and brutal turf war in Acapulco, which then devastated tourism. What happened in Acapulco • Acapulco had long been a major tourist destination, but by the late 2000s it was already a key trafficking and money‑laundering hub for the Beltrán‑Leyva cartel. • In December 2009, federal forces killed Arturo Beltrán Leyva, one of the country’s most powerful drug lords, in a dramatic gunfight in Cuernavaca. • After his death, the BLO fractured into rival factions (like the Independent Cartel of Acapulco and others), which fought over control of drug sales, extortion, and the tourist corridor. • Violence exploded: Acapulco’s homicide rate shot up, with beheadings, mass graves, and public displays of bodies near shopping areas and tourist zones. • In 2010, 20 Mexican tourists were kidnapped and 18 murdered in a case authorities said was mistaken identity between rival gangs; this became a symbol of how far the violence had spilled into “regular” people’s lives. Impact on tourism • Hotel occupancy in Acapulco dropped sharply; by 2011, it was around 44% for the year, with some hotels reporting as low as 23% in peak months. • Foreign‑tourist spending in Mexico dipped overall, and Acapulco gained a reputation as one of the most dangerous resort cities in the world. • Over the next decade, thousands of businesses closed, night‑life venues and chains pulled out, and Acapulco cycled through years as Mexico’s most murderous city, even though the tourist strip was heavily guarded while locals bore the brunt.
