Casey Johnson Autopsy Results Reveal Possible Nyquil Addiction, No Illegal Drug Use

Earlier this month, a Los Angeles coroner confirmed that Casey Johnson died of diabetes-related complications. He specifically cited an issue known as "diabetic ketoacidosis," which is caused by a lack of insulin.

Yesterday afternoon, meanwhile, the L.A. County Coroner's Office released the official autopsy report for Johnson's death and it revealed a few details related to the tragedy:

• Casey's body was free from injury of any kind.
• Multiple medications found at the scene included Motrin, insulin and clonazepam.
• The report cites a "possible excess use of Nyquil."
• No illegal drugs were found in Johnson's system.

Two sad notes related to the Johnson & Johnson family heiress: her death was preventable if she had taken better care of herself; and her body may have been found on January 4, but it lay in her home, undiscovered, for days.
