Pedro Oliverio Guerrero Bloque in the Guaviare department. As such, he got involved in drug trafficking and soon got involved in many violent vendettas over the control of territory and drug trafficking routes. He survived the war for the control of the department of Casanare between the Bloque Centauros and the paramilitary group of Héctor Germán Buitrago ("aka" Martín Llanos), and then was blamed as the author of the death of his own boss, Miguel Arroyave by Salvatore Mancuso, who declared Guerrero a military target. Following the death of Arroyave, Guerrero became one of the leaders of the divided factions of Bloque Centauros.
