José Gonzalo Rodriguez Gacha (14 May 1947 – 15 December 1989), also known by the alias of El Mexicano (), was a Colombian drug lord who was one of the leaders of the Medellín Cartel along with the Ochoa brothers and Pablo Escobar. At the height of his criminal career, Rodriguez was acknowledged as one of the world's most successful drug dealers. In 1988, Forbes magazine included him in their annual list of the world's billionaires.U.S. Congress, Office of Technology AssessmentInformation Technologies for the Control of Money Laundering OTA-ITC-630, Washington, DC: U.S. Government Printing Office, September 1995

Early years José Gonzalo Rodríguez Gacha was born in May 1947 in the small town of Veraguas, near Pacho in the department of Cundinamarca. He came from a poor family of cheese vendors, and it is said that his formal education did not extend beyond grade school. He left school in the early 1970s and moved to Muzo, Boyacá, the center of the emerald exploitation in Colombia. There he began to work under Gilberto Molina Moreno, who at the time was called the "tsar" of emeralds in Boyacá, as part of his security, developing a fearsome reputation as a killer. As he started to go up in the ranks among Molina's men, he also became acquainted with drug traffickers. At some point, Rodríguez Gacha decided that the drug business was more profitable and became independent. He moved to Bogotá and became associated up with Verónica Rivera de Vargas, a pioneering drug trafficker who was known as the "queen of cocaine," by murdering the family of her main rival.'Drug Kingpin 'El Mexicano' Is Violent Empire-Builder : 40-Year-Old a Symbol of Cocaine Wealth'. The Washington Post, November 14, 1987 Rivera introduced him to Pablo Escobar and to Mexican drug lord, Miguel Ángel Félix Gallardo.

Rise of the Medellín Cartel As he started to prosper in the drug trafficking business, Rodríguez Gacha started to buy larger amounts of land in the Middle Magdalena region in the valley bordering the departments of Antioquia, Boyacá, and Santander. After moving to Medellín in 1976, Rodríguez Gacha associated with the Ochoa family, Pablo Escobar, and Carlos Lehder in establishing an alliance that eventually strengthened into what would become known as the Medellín Cartel. The traffickers cooperated in the manufacturing, distribution and marketing of cocaine. During the late 1970s, Rodríguez advanced in the organizational hierarchy, pioneering new trafficking routes through Mexico and into the United States, primarily Los Angeles, California and Houston, Texas. He is often said to have been the first to establish cooperation strategies with drug trafficking cartels in Mexico. This, coupled with his infatuation with Mexican popular culture, music, and horse culture, and his fondness for foul language, earned him the nicknames El Mexicano (the Mexican). He owned a string of farms in his hometown in the locality of Pacho with Mexican inspired names such as Cuernavaca, Chihuahua, Sonora and Mazatlán.

According to the US Justice Department, Rodríguez directed cocaine trafficking operations through Panama and the West Coast (California) of the United States. It is claimed that he helped design a Nicaraguan trafficking operation that employed pilot Barry Seal (who was murdered on February 19, 1986, after agreeing to testify against the Medellín Cartel).

Rodríguez Gacha based much of his operations from Bogotá and other areas in the Cundinamarca region, as well as in the Middle Magdalena region. It was Rodríguez who first set up Tranquilandia, one of the largest and best known of the jungle laboratories where more than two thousand people lived and worked making and packaging cocaine. ["The Accountant's Story", by Roberto Escobar].

As he became one of the main capos of the rising Cartel, Rodríguez Gacha started having problems with the FARC guerrilla, mostly derived from the fact that the insurgent army taxed some of his coca plantations, and that they sometimes robbed some of his men. When the M-19 guerrilla kidnapped Martha Nieves Ochoa, the sister of fellow drug lord Jorge Luis Ochoa, the cartel decided to create what would be one of the first far-right paramilitary groups to fight the guerrillas, the "Muerte a Secuestradores" (MAS) [Death to Kidnappers] movement. Rodríguez Gacha became one of the main economic supporters of the group. He soon became the de facto military leader of the cartel and thanks to his immense riches, he managed to form the largest paramilitary organization in the country, composed of around 1,000 men, all trained and armed, originally devoted to his security but soon becoming an anti-communist army directed particularly against the FARC, and then against the Unión Patriótica political party.

Lara assassination On March 7, 1984, the Colombian Police and the DEA destroyed Rodríguez Gacha's Tranquilandia complex. A few weeks later, on April 30, 1984, Colombian Minister of Justice Rodrigo Lara, who had crusaded against the Medellin Cartel, was assassinated by armed men on a motorcycle. In response, President Belisario Betancur, who had previously opposed extradition, made an announcement that "we will extradite Colombians." Carlos Lehder was the first to be put on the list. The crackdown forced the Ochoas, Escobar and Rodríguez to flee to Panama for several months. A few months later, Escobar was indicted for Lara's murder and Rodríguez was named as a material witness. In an attempt to handle the situation, Escobar, Rodríguez and the Ochoa brothers met with the former Colombian president Alfonso López in the Hotel Marriott in Panama City. The negotiation failed after news of it leaked to the press, provoking the open opposition of the United States to any immunity deal.Alonso Salazar J, La Parábola de Pablo: Auge y caída de un gran capo del narcotráfico (Santafé de Bogotá: Editorial Planeta, 2001), pp. 129-131.

Cartel-linked paramilitary groups

Paramilitary groups (or self-defense groups, autodefensas as they are frequently referred to in Colombia), were created with the support of landowners and cattle ranchers who had been under pressure from the guerrillas as well as from groups affiliated with narcotics traffickers such as the Muerte a Secuestradores movement (MAS – Death to Kidnappers). As made clear in a 2004 judgment of the Inter-American court of Human Rights,See the Judgement of the Court of July 5, 2004 in the Case of 19 Merchants, paragraphs, 84a-84d numerous independent reports and from what the paramilitaries themselves have said, in at least some cases they were given support by the state itself.In the speech, the Magdalena Medio commander present at the Congress of the Republic on July 28, 2004, he said: “we went to Base Calderón, now the Barbula battalion, we stated what we wished to do and they helped us with 8 shotguns and munitions…and then on February 18, 1978, the now Peasant Self Defence of the Magdalena Medio Antioqueno were both.” The top leaders of the Medellín Cartel created private armies to guarantee their own security and protect the property they had acquired. According to The Washington Post, in the mid-1980s, Rodríguez and Pablo Escobar bought huge tracts of land in the Magdalena Department (as well as Puerto Boyacá, Rionegro and the Llanos) which they used to transform their self-defense groups from poorly trained peasant militias into sophisticated fighting forces.Doug Farah, "Massacres Imperil U.S. Aid to Colombia Paramilitary Groups Linked to Army, The Washington Post, January 31, 1999, A01 By the late 1980s Medellin traffickers controlled 40% of the land in the Middle Magdalena, according to a Colombian military estimate, and also funded most of the paramilitary operations in the region.

Throughout the 1980s, Rodríguez helped catalyze the Medellín Cartel's explosive rise to power by financing the importation and implementation of expensive foreign technology and expertise. According to the report by the Departamento Administrativo de Seguridad (Colombia's Administrative Security Department), between December 1987 and May 1988, Rodríguez hired Israeli and British mercenaries to train teams of assassins at remote training camps in Colombia. Yair Klein, a retired Israeli lieutenant colonel, acknowledged having led a team of instructors in Puerto Boyacá in early 1988.Colombian Security Alleges Mercenary Aid to Cartels. August 29, 1989, Washington Post Foreign Service It is not clear whether Klein's mercenary activities in Colombia coincided with those of a group of British mercenaries who had allegedly trained paramilitary squads for the cocaine cartels.Tony Thompson, ‘High-tech Crime of the Future Will be all Mod Cons’, The Observer, October 3, 1999, The Omega Foundation (Manchester, UK) carried out a study of new security technologies for the Scientific and Technological Options Assessment Panel at the request of the Committee on Civil Liberties and Internal Affairs of European Parliament in January 1998

American fight against drugs By 1989, the Drug Enforcement Administration (DEA) estimated that 80 percent of cocaine consumed in the United States was imported from Colombia by the Medellín Cartel and its rival, the Cali Cartel. The newly elected administration of President George H. W. Bush was under considerable pressure to combat the increasing drug usage and drug-related violence plaguing scores of American cities. Much of the government strategy concentrated on restricting drug supply by extraditing Colombian cartel leaders to the United States for prosecution. On August 21, 1989, Attorney General Dick Thornburgh released a list of the twelve Colombian drug kingpins (commonly referred to as the "dirty dozen") most wanted by the United States and said the names would be shared with the Colombian government and Interpol. The list included Pablo Escobar, Jorge Luis Ochoa, and José Gonzalo Rodríguez, the leading members of the Medellín Cartel.

Financial crackdown President Bush declared money laundering a critical target in the war on drugs, allocating $15 million to launch a counteroffensive. Only hours after Bush unveiled his antidrug offensive in September 1989, a federal task force began taking shape. The Financial Crimes Enforcement Network (FINCEN) was designed to zero in on money launderers with computer programs capable of spotting suspicious movements of electronic money. On December 6, 1989, Attorney General Dick Thornburgh announced that authorities had frozen accounts in five countries holding $61.8 million belonging to Rodriguez Gacha. According to the Justice Department, the money represented long-term high-yield stocks and investments and was held in bank accounts in England, Switzerland, Austria, Luxembourg and the United States. An additional $20 million of Gacha's drug money was suddenly transferred to Panama, where it was protected from American authorities.Jonathan Beaty and Richard Hornik, "A Torrent of Dirty Dollars", Time magazine, Posted June 24, 2001

Rodríguez Gacha's final years The growth of Rodríguez Gacha's criminal empire had allowed him to increase his fortune but also made him a lot of enemies. By 1987, animosity started with the Cali Cartel, his previous partners in MAS, as he attempted to move in on the New York City market. The animosity turned into an open cartel war in 1988, moved mostly by the personal vendetta of Pablo Escobar against Pacho Herrera. As the military leader of the cartel, Rodríguez Gacha was instrumental in many assassinations and distribution violent actions against the Cali Cartel.
