The Medellin Cartel was a ruthless, highly organized and much-feared Colombian drug cartel originating in the city of Medellin, Colombia. The drug cartel operated throughout the 1970s and 1980s in Bolivia, Colombia, Central America, Peru, and the United States, as well as in Canada and Europe. It was founded and run by Ochoa Vazquez brothers Jorge Luis, Juan David, and Fabio, together with Pablo Escobar, George Jung, Ishaq Velasco, Carlos Lehder and Jose Gonzalo Rodriguez Gacha. By 1993, the resistance group, Los Pepes (or PEPES), controlled by the Cali Cartel, and the Colombian government, in collaboration with the Cali Cartel, right-wing paramilitary groups, and the United States government, had dismantled the Medellin Cartel by imprisoning or assassinating its members.
