Police said that members of Pacheco's gang, who were serving as his bodyguards, called the emergency number to reveal that they had murdered the drug boss, according to reports.
Pacheco is thought to have been killed by gang members known as "Muelas" and "El Negro." His body was found tied to a tree and bearing signs of torture, in the Bajo Cauca region of the central Colombian Antioquia department.
The deceased gang leader was a member of the paramilitary group United Self-Defense Forces of Colombia (Autodefensas Unidas de Colombia - AUC). He joined the Paisas drug gang after the AUC demobilized, and later left that group to join the Rastrojos, a descendent of the Norte del Valle drug trafficking cartel.
