ORLANDO, Fla. (AP) — An autopsy 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 drug overdose. A report released Wednesday by the Orange County Medical Examiner's Office concluded that Victoria Siegel's death was the result of methadone and sertraline toxicity.
