George "Boston George" Jung belonged to the Medellin Cartel --the notorious collective of drug suppliers responsible for nearly 90 percent of the cocaine smuggled into the U.S. during the 1970s and '80s.
He was introduced to the Medellin Cartel by cellmate and Columbian-born drug dealer, Carlos Lehder. Together Jung and Lehder moved pounds upon pounds of cocaine between Columbia and the U.S. bringing in billions for the Medellin Cartel, but by 1987 Jung was sentenced to 60 years in prison.
Jung copped a plea for testifying against Lehder, and is now scheduled to be released this November. He's also the same guy Johnny Depp portrayed in the film Blow.
