Johnson & Johnson heiress Casey Johnson’s cause of death was determined as natural, a result of diabetic ketoacidosis, which is a severe state of insulin deficiency. The 30 year-old socialite’s body was found several days after she passed away at her apartment on January 4, 2010.

Sources tell TMZ, Casey was not talking her insulin shots. She also didn’t exercise, follow her diet or take other meds she needed. Casey had been hospitalized twice before for diabetic coma.
