Simon Monjack with the beauteous Brittany.
According to TMZ Brittany Murphy's husband, Simon Monjack aka What The Fuck Is She Doing With Him? told Cedars-Sinai Medical Center that he didn't want an autopsy performed on his deceased wife. Uh, Earth to husband. That's not exactly your call to make. We have a heretofore healthy (as far as we know) 32 year old woman found dead in the shower. And we have the husband not wanting an autopsy? Red flag! Red flag!
Now, in fairness, he could be in total shock and just wanting to protect the integrity of his beautiful wife's body. But that's not how it works. If I had to bet, the autopsy will be inconclusive and the causes will be "pending toxicology". I've seen it a hundred times. It's possible, but as a rule, 32 year olds don't just collapse and die in the shower.
