The death certificates for the two Hollywood stars, Debbie Reynolds and Carrie Fisher, who died one day apart, were released Monday by the Los Angeles County Department of Public Health. The certificates show that Reynolds died from a stroke and her daughter Fisher, died from cardiac arrest -- although the precise cause of death of the "Star Wars" actress will require more investigation. Fisher, the 60-year-old actress was hospitalized on December 23 after a cardiac event on a flight from London to Los Angeles. Four days later, her death was confirmed in a statement issued by the publicist for Billie Lourd, Fisher's daughter. The day after Fisher's death, Reynolds -- one of Hollywood's biggest stars in the 1950s and 1960s -- was taken to a Los Angeles hospital where she later died. On her death certificate, her cause of death was listed as "intracerebral hemorrhage," which is a type of stroke.
