What killed Bruce Lee? Drug rumours add to the mystery surrounding the death of the Hong Kong martial arts actor
- When Bruce Lee died suddenly at the age of 32, conspiracy theories about his death started to circulate immediately
- Letters found recently, referring to the supply of various illegal drugs, have ignited new speculation about his death

These rumours took a darker turn in July this year when more than 40 letters were unearthed that implied the martial arts legend was a secret drug user.
British tabloids The Sun and Daily Mirror reported that the handwritten letters to Hollywood actor and Fist of Fury co-star Robert “Bob” Baker suggest he supplied Lee with an array of drugs over a five-year span. Drugs such as cocaine, LSD and cannabis were mentioned in the letters, which covered the period up until his death.
The letters were discovered at a flea market in the United States. After being verified by Professional Sports Authenticator, a leading authenticator of celebrity autographs, they were all sold in July for US$462,500 by American auction house Heritage Auctions. Bids on individual letters ranged from US$600 to more than US$10,000.
