Actress Brittany Murphy died Sunday morning after going into full cardiac arrest, TMZ reports, and the coroner's officer has said her death appears to be from natural causes, though a toxicology report won't be available for some time. Murphy's mother reportedly found her unconscious in the shower of her Los Angeles home, and told paramedics that she had a history of diabetes. The paramedics tried to resuscitate her, but she was declared dead on arrival at Cedars-Sinai Medical Center. Murphy's husband, Simon Monjack, does not want an autopsy performed on his wife, TMZ reports, although The Los Angeles County Coroner will reportedly perform an autopsy on Monday. Murphy was known for her roles in Clueless, 8 Mile, and Don’t Say a Word. Earlier this month, there were rumors she was fired from the set of a film shooting in Puerto Rico.
