Was Anna Nicole Murdered?

Let me just first start off by saying, that this is not a conspiracy theory. I hate conspiracy theories. I remember I while back watching Nancy Grace interview the mother of Anna Nicole, Virgie Mae Tabers Hogan, and Nancy asked Virgie what she would say to her daughter (they are not speaking). Ms. Hogan who was a law enforcement officer for 28 years replied, (I'm paraphrasing here), Anna, you better watch your step, because Danny did not die of an overdose and you might be next.
And here we are.

I'm probably wrong, who knows?

Here's a corroborating story that I just found with some actual quotes.
