Ismael Zambada García (born 1 January 1948), also known as El Mayo Zambada, is a Mexican drug lord who serves as the leader of the Sinaloa Cartel.
 Before assuming leadership of the entire cartel, he served as the logistical coordinator for the Zambada-García faction of the Sinaloa Cartel which has assisted in the exporting of cocaine and heroin into Chicago and other U.S. cities by train, ship, jet and submarine.
Javier Torres Félix (born 19 October 1960) is an imprisoned Mexican drug lord and former high-ranking leader of the Sinaloa Cartel, a drug trafficking organization.
 He is the brother of the deceased drug lord Manuel Torres Félix and the former right-hand man of Ismael "El Mayo" Zambada, a top cartel leader.
The Sinaloa Cartel (Spanish: "Cártel de Sinaloa" or "CDS" ) is an international drug trafficking, money laundering, and organized crime syndicate.
 Established during the mid-1980s, the Sinaloa Cartel is based primarily in the city of Culiacán, Sinaloa, with operations in the Mexican states of Baja California, Durango, Sonora, and Chihuahua.
 The cartel is also known as the Guzmán-Loera Organization and the Pacific Cartel, the latter due to the coast of Mexico from which it originated.
 The cartel has also been called the Federation and the Blood Alliance.
 The 'Federation' was partially splintered when the Beltrán-Leyva brothers broke apart from the Sinaloa Cartel.
The 2012 Nuevo Laredo massacres were a series of mass murder attacks between the allied Sinaloa Cartel and Gulf Cartel against Los Zetas in the border city of Nuevo Laredo, Tamaulipas, across the U.S.-Mexico border from Laredo, Texas.
 The drug-violence in Nuevo Laredo began back in 2003, when the city was controlled by the Gulf Cartel.
 Most media reports that write about the Mexican Drug War, however, point to 2006 as the start of the drug war.
 That year is a convenient historical marker because that's when Felipe Calderón took office and carried out an aggressive approach against the cartels.
 But authors like Ioan Grillo and Sylvia Longmire note that Mexico's drug war actually began at the end of Vicente Fox's administration in 2004, when the first major battle took place in Nuevo Laredo between the Sinaloa Cartel and Los Zetas, who at that time worked as the armed wing of the Gulf Cartel.
Inés Coronel Barreras (born 21 January 1968) is a convicted Mexican drug lord and former high-ranking leader of the Sinaloa Cartel, a drug trafficking organization.
 He is the father-in-law of Joaquín "El Chapo" Guzmán, the former leader of the cartel and once considered Mexico's most-wanted man.
 Coronel Barreras was arrested by Mexican security forces in Agua Prieta, Sonora on 30 April 2013.
 He was sentenced to 10 years in prison on April 28, 2017 for drug trafficking and illegal possession of firearms.
Los Mexicles is a Mexican street gang, who work as armed wings for two of Mexican drug cartels, Sinaloa Cartel and Gulf Cartel.
 For the Gulf Cartel, they work in South Texas and Rio Grande Valley as armed wing and drug traffickers and dealers.
 For the Sinaloa Cartel, they work in Ciudad Juárez as assassins for the cartel.
Los Ántrax is an enforcer gang of the Mexican drug trafficking organization known as the Sinaloa Cartel.
 The group was led by the drug lords Jesús Peña ("El 20") and Rodrigo Aréchiga Gamboa ("El Chino Ántrax"), and they are responsible for a number of homicides and for providing armed security services to Ismael "El Mayo" Zambada.
 The gang operates in the capital city of Culiacán, Sinaloa, where its members conduct homicides and violent attacks.
Juan José Esparragoza Moreno (born February 3, 1949), commonly referred to by his alias El Azul (English: "The Blue One"), is a Mexican drug lord and leader of the Sinaloa Cartel, a drug trafficking organization.
 Originally a member of the Dirección Federal de Seguridad (DFS) police agency, he founded the Guadalajara Cartel in the 1970s along with other drug kingpins in Mexico.
 Following its disintegration in the late 1980s, he went on to lead the Juárez Cartel, and eventually settled in the Sinaloa Cartel.
 He worked alongside Joaquín "El Chapo" Guzmán, once considered Mexico's most-wanted drug lord.
Serafín Zambada Ortiz (born 27 May 1990) is a United States-born Mexican drug trafficker and son of Ismael "El Mayo" Zambada, one of the top leaders of the Sinaloa Cartel.
 He is married to Karime Ellameli Torres Acosta, the daughter of the late Manuel Torres Félix ("The Crazy One"), another Sinaloa Cartel drug lord.
 Zambada Ortiz was active on social media, where he posted pictures of his extravagant lifestyle.
Gonzalo Inzunza Inzunza (17 August 1971 – 18 December 2013), commonly referred to by his alias El Macho Prieto, was a Mexican drug lord and high-ranking leader of the Sinaloa Cartel, a Mexican transnational criminal organization.
 He worked as the cartel's assassins chief under the tutelage of Ismael "El Mayo" Zambada and as the regional leader of the cartel in the states of Baja California and Sonora.
 His base of operations was in Mexicali, where he coordinated marijuana and cocaine shipments through the Calexico–Mexicali border region.
 On 18 December 2013, Inzunza Inzunza was killed in a shootout with Mexican authorities in the resort area of Puerto Peñasco, Sonora.
 Before the gunfight was over, several of his gunmen took the corpse of the drug lord with them.
