Although originally a part of The Sinaloa Cartel, the four Beltrán Leyva brothers broke ties with the organization in 2008 after Alfredo Beltrán Leyva was arrested by Mexican military special forces, and the Beltrán Leyva brothers assumed their boss Joaquin Guzman Loera (a.k.a. El Chapo) had betryaed them. In response to the supposed betrayal, the Beltrán Leyva brothers ordered the murder of 22 year-old Édgar Guzmán López, a son of Joaquín Guzmán, who was killed in a shopping center parking lot by at least 15 gunmen using assault rifles and grenade launchers.
The remaining four Beltrán Leyva brothers established The Beltrán-Leyva Cartel and forged a collaboration pact with their former rivals: The Gulf Cartel and The Los Zetas Organization. Today, the Beltrán Leyva Cartel is responsible for the procurement of fire arms and ammunitions from the United States in furtherance of their criminal enterprise and is responsible for the trafficking of multi-ton amounts of illicit drugs, including cocaine, marijuana, heroin, and methamphetamine. Héctor Beltrán Leyva is also credited with rising rates of violence within Mexico, as his organization is reportedly responsible for kidnapping, torture, murder, and various other acts of violence against numerous men, women, and children in Mexico. The cartel is considered one of the most ruthless and brutal in the way they dispose of their enemies. The organization is connected with the assassinations of numerous Mexican law enforcement officials, including Édgar Eusebio Millán Gómez, the former acting commissioner of the Mexican Federal Preventive Police.
The U.S. Department of State is currently offering a reward of USD $5 million for information leading to the arrest and/or conviction of Héctor Beltrán Leyva, while the Mexican government is offering a USD $2.1 million reward.
