Khun Sa aka "Prince Prosperous" was a flashy character who switched up his name from Chang Chi-fu and stepped foot into the heroine game in the mid-70s. The Burmese drug lord was leader of the nonconformist group the Shan State Army, and ruler of the Golden Triangle -- comprised of three opium-producing countries Thailand, Laos and Myanmar (Burma).
Sa escaped an assassination attempt in 1981 (39 men tried to take him out), eluded U.S. prosecution for smuggling 1,000 pounds of heroin, and lived the rest of his life in Southeast Asia.
It is estimated that Sha's net worth was $5 billion. He passed away in 2007 of unknown causes.
