Casey Johnson died of diabetes-related condition, L.A. County coroner says
The 30-year-old heiress to the Johnson & Johnson empire and daughter of New York Jets owner Woody Johnson died Jan. 4 at her Westside home.
Coroner's officials determined her "natural death" to be a result of diabetic ketoacidosis, a complication of diabetes that occurs when the body cannot use glucose because it has inadequate insulin and fat is used instead. As the fat is broken down, acids called ketones build up in the blood and urine to poisonous levels.
A preliminary investigation by police homicide investigators had found nothing to suggest that Johnson died of anything other than natural causes.
And sources with the Los Angeles Police Department had said they believed the cause was "medically related."
The personal life of Johnson, the girlfriend of reality TV star Tila Tequila, has long been a staple for celebrity gossip sites and tabloids including Page Six, which dubbed her the "baby-oil heiress."
Johnson, whose given name was Sale Trotter Case Johnson, was diagnosed with diabetes as a child.
