An autopsy released on Wednesday shows that the 18-year-old daughter of the stars of the Queen of Versailles documentary who had struggled with an addiction to a drug used to control her seizures died last month of an accidental overdose.

Victoria Siegel’s death was the result of methadone and sertraline toxicity, the report by the Orange County Medical Examiner’s Office concluded. The examination found significant concentration of both drugs.

Siegel was found unresponsive by a housekeeper at the family’s Windermere mansion on June 6 and pronounced dead at a hospital. Family attorney Michael Marder said last month that Siegel had previously undergone voluntary rehabilitation to shake her dependence on prescribed medication to control seizures.

According to the Centre for Disease Control and Prevention website, Methadone is a drug used to treat drug addiction. Sertraline, also sold as Zoloft, is prescribed to treat depression.

Before her death, Siegel had undergone voluntary rehabilitation to shake her dependence on a drug to control her seizures, Marder said in a statement last month. He said it could not be determined whether the drugs she took were prescribed medication.

Victoria Siegel was the daughter of David and Jackie Siegel, stars of the 2012 documentary, Queen of Versailles. The movie chronicled their extravagant lifestyle, including an effort to build a 8,360-sq metre mansion.

David Siegel is the founder of Westgate Resorts, an Orlando-based timeshare empire. The documentary also followed his company’s struggles during the economic downturn. Jackie Siegel is a former Mrs Florida America and has been a director of the pageant.
