The actress' cause of death is listed on the document as "deferred"; as reported earlier, it may take four to six weeks for toxicology, histiological and neurological test results to become available.
Tayebe Pajooh, Murphy's cousin, is listed on the certificate as the informant; Pajooh provide the mortuary with information on her late cousin.
One surprise: the death certificate fails to name Murphy's estranged father, Angelo Bertolotti. Instead, the document lists Murphy's father as "Unknown."
Bertolotti divorced Sharon Murphy, Brittany's mom, when Brittany was two, and spent time in a federal prison on drug charges. He admitted to UsMagazine.com that he hadn't spoken to his daughter in "about three years."
"She had a beautiful smile," Bertolotti told Us. "I was so proud of her. She was loveable."
