The autopsy report for Victoria Siegel -- the late daughter of Queen of Versailles stars David and Jackie Siegel -- was obtained by ET on Wednesday, and shows the 18-year-old died of "acute methadone and Sertaline toxicity."
The Office of the Medical Examiner in Orlando, Florida, found a significant concentration of both methadone (a drug used for pain treatment, and also to reduce withdrawal symptoms in people addicted to certain narcotics like heroin) and the antidepressant Sertraline in Victoria's system. The department also found linear scars of up to 5 cm. on the inside of her left wrist. The death has been ruled an accident.
Victoria died on June 6, when she was found unresponsive at the family's Windermere, Florida home, and then later pronounced dead at the hospital. Her family said that the teenager was battling an addiction to prescription medication prior to her death.
"Victoria had a history of seizures and was prescribed medication for this condition. Unfortunately she became dependent and struggled with this condition," the Siegel family said in a statement. "She voluntarily underwent rehabilitation and was working hard to address this problem."
Victoria's funeral took place on June 9 at St. Luke's United Methodist Church in Orlando, Florida, with a private burial service at Woodlawn Cemetery. In lieu of flowers, the Siegels asked that mourners honor their late daughter’s memory with contributions to the Victoria Siegel Memorial Fund, which will "help troubled teens get the guidance and assistance they need to live a healthy and positive life."
"Victoria was a beautiful spirit with a wonderful smile who was greatly loved, and will be deeply missed," the family said in a statement last month.
David and Jackie, owners of Westgate Resorts, first rose to fame as the subjects of the 2012 documentary The Queen of Versailles. They were also featured in an episode of ABC's Wife Swap.
