Was Whitney Houston Murdered?

Spoiler alert to the title, no she wasn't. Yet for some reason Nancy Grace was on CNN implying that Whitney Houston's death was more then the obvious drug involved/accidental death that it was. Sparking the controversy of "who pushed Whitney under water?"

Fox News
Grace likened Houston's death to those of Michael Jackson and Anna Nicole Smith, before asking if any of those in the hotel room with Houston when she died may have been complicit in her death.
"I'd like to know who was around her, who, if anyone gave her drugs, following alcohol and drugs, and who let her slip, or pushed her, underneath that water?" Grace responded. "Apparently no signs of force or trauma to the body. Who let Whitney Houston go under her water?"

Who let her go under water? What is Nancy Grace so fat the she thinks it's impossible for somebody to slip under the surface of water without "assistance"?

Grace is an idiot. They should've gotten Justin Bieber on CNN to ask what he think happened instead of Nancy Grace. Even he wouldn't have made some stupid comment like this. In fact, CNN themselves are now working to distance themselves from the comments made by this moron.
