Alberto Suarez was a Search Bloc policeman from Colombia who was hired by DEA agents Javier Pena and Steve Murphy to track down the man who killed his cat. Suarez interrogated the customs officials that stalled Murphy and scanned his passport, discovering that the killer Roberto Ramos (better known as "Poison") killed the cat and had attempted to kill Murphy and his wife at their home. However, he was in Pablo Escobar's pocket, and he warned Ramos that Colonel Horacio Carrillo was going to ambush him, with Escobar paying him 5% of his money in gratitude for Suarez selling the police out. Ramos evaded the police, escaping successfully.
However, the DEA would continue contacting him, hoping to find out people who might know of Escobar's criminal record ahead of the 1982 congressional election. Suarez was paid to give them names, but he warned Escobar each time for more money; Escobar had these people killed. In 1989, Murphy met him for the last time, forcing him to give the name of Efram Gonzalez, an ETA bomb-maker who was recruited by Escobar. Suarez called Escobar to tell him that the DEA agent was Murphy, but Escobar was angry that he talked with the DEA. Poison headed to Suarez's house and shot him in the leg before shooting him in the chest, killing him.
