Yes! George Jung, better known as Boston George, is still alive and is 70 years old. The movie Blow chronicled his life story and was such a success that it made him a prison celebrity.
George Jung was a smuggler in the coke trade in the 1970's and early 1980's for the Medellin Cartel. He was responsible for up to 89% of coke that was smuggled into the U.S. during that time.
George was arrested on a number of occasions before he was finally convicted of conspiracy in 1994 and was sentenced to 15 years in prison. He is currently in Fort Dix Federal Correctional Institution in Fort Dix, New Jersey, with a scheduled release date of November 27, 2014.
