The mother and daughter passed away within a day of each other.
The death certificates of Carrie Fisher and Debbie Reynolds have confirmed the Star Wars actress and Singin' in the Rain star died of cardiac arrest and a stroke, respectively.
In Fisher's case, however, the Los Angeles Coroner's Office is conducting more tests to determine what exactly caused her heart attack aboard a December 23 flight to LAX from London.
According to reports, the tests on Fisher will also include a toxicology report to determine if there were drugs in her system.
The 60-year-old Star Wars actress passed away on December 27. The day after her passing, her 84-year-old mother, Debbie Reynolds passed away of a intracerebral hemorrhage — commonly known as a stroke.
The mother and daughter were laid to rest in Los Angeles Friday. Fisher was cremated and her ashes were placed in an urn that resembled a massive Prozac pill.
