Pablo Escobar
Los Pepes, a name derived from the Spanish phrase "Perseguidos por Pablo Escobar" ("Persecuted by Pablo Escobar"), was a vigilante group composed of enemies of Pablo Escobar. They waged a small-scale war against the Medellín Cartel in the early 1990s, which ended in 1993 following the death of Escobar. The group was financed by the Cali Cartel and was led by the Castaño brothers. An example of their acts could be seen on the streets of Medellín, such as hangings of Pablo's sicarios.
