Escobar eventually became involved in many criminal activities with Oscar Benel Aguirre, with the duo running petty street scams, selling contraband cigarettes, fake lottery tickets, and stealing cars. In the early 1970s, prior to entering the drug trade, Escobar acted as a thief and bodyguard, allegedly earning US$100,000 by kidnapping and holding a Medellín executive for ransom. Escobar began working for Alvaro Prieto, a contraband smuggler who operated around Medellín, aiming to fulfill a childhood ambition to have COL $1 million by the time he was 22. He is known to have had a bank deposit of COL 100 million (more than US$3 million), when he turned 26.
