Brittany Murphy’s Husband Simon Monjack: How Did This Happen?

In an all-new interview, Brittany Murphy's husband Simon Monjack is speaking out just two days after his wife's untimely death.

"How did it happen? Her mum, myself and her family -- we want to know why we lost our baby," he tells People.com.

Monjack says he hasn't slept since his mother-in-law found Murphy in the bathroom early Sunday morning and that although he didn't initially like the idea of an autopsy, he knew it was necessary.
