The world lost a beautiful and talented soul on Sunday. We know that. We don't know why or how Brittany Murphy was taken from us. Autopsy results won't be released for 4-6 weeks, and even then we may have only a vague idea of what killed the 32-year-old. We do know when Murphy was last seen in public. We know when she was found by her mother. And we know that her friends, family and fans are beyond sad to see her gone.
