Anna Nicole Smith was determined to emulate Marilyn Monroe. She certainly achieved that in life; also in her death.
With Smith dying in such mysterious circumstances, and with so much death and dysfunction around her (not to mention all that power and money), conspiracy buffs will be postulating like crazy. Just like Marilyn, Smith is sure to spawn a plethora of theories about what really killed her.
You'll see in this summary of Monroe's death that most of the hypotheses are way too far-fetched. (Except the one about the commies doing it. Would be just their style, I reckon.)
I'm sure that one day Anna Nicole Smith will have a similar page on the same site. Anyone wanna have a stab at what it might contain?
