Jung was a part of the Medellín Cartel, which was responsible for up to 89 percent of the cocaine smuggled into the United States. He specialized in the smuggling of cocaine from Colombia on a large scale. His life story was portrayed in the biopic Blow (2001), starring Johnny Depp. Jung was released from prison on June 2, 2014, after serving nearly 20 years for drug-smuggling.
