Rafael Caro Quintero ran one of the largest drug smuggling operations in Mexico in the 1980s. The drug lord seemed virtually untouchable until he was arrested in 1985. 

Released from jail after serving 28 years, the US State Department is now seeking to arrest Quintero for crimes he committed in the US and are offering a $5 million reward for help finding and convicting him.
