Beltrán-Leyva Organization
Mexican drug cartel and organized crime syndicate

The Beltrán Leyva Organization (BLO), also known as the Beltrán Leyva Cartel (Spanish: Cártel de los Beltrán Leyva, pronounced [ˈkaɾtel ðe los βelˈtɾan ˈlejβa], CBL), was a Mexican drug cartel and organized crime syndicate, formerly headed by the five Beltrán Leyva brothers: Marcos Arturo, Carlos, Alfredo, Mario Alberto, and Héctor. Founded as a Sinaloa Cartel, the Beltrán Leyva cartel was responsible for transportation and wholesaling of cocaine, heroin and marijuana (and the production of the last two). It controlled numerous drug trafficking corridors, and engaged in human smuggling, money laundering, extortion, kidnapping, murder and gun-running.
The BLO was one of Mexico's most powerful drug cartels, which had effectively infiltrated the ranks of various Mexican government agencies and Mexico's Interpol. Its last known leader, Héctor Beltrán Leyva, was arrested in October 2014, having had a multimillion-dollar bounty placed on him by the governments of both the United States and Mexico. On August 11, 2011 the capture of one of the cartel's former top lieutenants, called "the last Beltran-Leyva link of any importance", prompted Mexican authorities to declare the cartel disbanded and extinct.
History
Born in the Sinaloan countryside in the 1960s, the Beltrán Leyva brothers—Arturo, Carlos, Alfredo, Mario Alberto and Héctor—worked closely with their cousin, Joaquín "El Chapo" Guzmán, the leader of the Cartel, during decades of smuggling. Sensing a void in the rival Gulf Cartel after Osiel Cárdenas' arrest on March 14, 2003, the organization began to move into Gulf Cartel territory. The gangs fought each other in northern Mexican cities, resulting in the deaths of hundreds of people, including some civilians, police and journalists.
In 2004 and 2005, Arturo Beltrán Leyva led powerful groups of assassins to fight for trade routes in northeastern Mexico for the Cartel.

Why this record matters
The phrase “mexican drug cartel and organized crime syndicate” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q816215. VIAF identifies the subject as 235743062. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2014, 2011, 2003 and 2004.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
