While the certificate says an official cause for death is still "pending chemical analysis" for 20-year-old Daniel Wayne Smith, two separate sources close to the official Bahamian investigation confirmed the existence of three separate drugs in Daniel's bloodstream -- the same drugs found last week by Anna Nicole's private pathologist Dr. Cyril Wecht.

Daniel Smith died in the Bahamas on September 10 while visiting his mother who had just given birth to a baby girl.
