Victoria Siegel, the teenage daughter of David and Jackie Siegel and one of the stars of the 2012 documentary “The Queen of Versailles,” was found dead at her family’s home in Windermere, Florida, on Saturday. The 18-year-old was discovered by the Siegels’ housekeeper.

Police were called to the home at approximately 2 p.m. CPR was performed on Siegel, who was then rushed to Health Central Hospital in Ocoee, where she was pronounced dead, according to WKMG-TV Orlando 6. Her cause of death is still under investigation.

“It is with great sadness that we ask you to respect our privacy during this tragic time and the loss of our beloved daughter, Victoria. Thank you all for your prayers and for your support,” Jackie Siegel wrote on her Facebook page Sunday. “As more information comes out, the family will share it; until that time, there is no comment.”

“The Queen of Versailles” followed Siegel’s parents, Jackie and David, owners of the Florida timeshare company Westgate Resorts, as they created their private residence. Dubbed Versailles, the house is one of the largest and most expensive single-family homes in the U.S. The film, which also featured Victoria, who according to her Facebook page, went by the nickname Rikki, featured the struggles the family faced after the 2008 recession.

Jackie, a former Miss Florida contestant, is 30 years younger than David. The couple filed a civil action suit against director Lauren Greenfield, claiming she had not obtained proper releases from the subjects of the film, particularly David and Westgate Resorts. The suit, which attempted to collect $5 million in damages, was dismissed in March of 2014, according to RealScreen.
