– Brittany Murphy's autopsy is complete, but the LA county coroner's office won't determine an official cause of death until after the completion of toxicology tests, which could take as long as 2 months. The 32-year-old actress, who died yesterday after suffering cardiac arrest, was bleeding internally before her death, a source tells the Los Angeles Times. The body appeared "normal" and not unusually thin, another source tells TMZ.
