Anna Nicole Smith is about to find out exactly what caused the death of her son. CNN is reporting that the results for Daniel Smith's autopsy rules out homicide, suicide and most natural causes. Reports are hinting that the death was due to the combination of multiple drugs that reacted negatively in Daniel's body.

Two autopsies -- one by the Bahamas coroner's office, another by celebrity pathologist Cyril Wecht -- have ruled out suicide, foul play and several potential natural causes. Both have sought further tests to detect drugs or chemicals.
Wecht, who was hired to perform a follow-up autopsy by Anna Nicole Smith, said Daniel had been taking a "quite low" dosage of prescription anti-depression medication.
"It is possible we might be dealing with one of those tragic and cumulative and drug-related deaths where somebody inadvertently takes two or three different kinds of drugs, each of which has a central nervous system effect," he said Monday night on CNN's "Larry King Live." (source)
