Victoria Siegel, the 18-year-old daughter of billionaire time share mogul David Siegel and former beauty queen Jackie Siegel, has died after being found unresponsive at their home near Orlando.

Orange County Sheriff’s spokesman Jeff Williamson said Victoria Siegel was found by deputies at the family’s home in Windermere on June 6. She was declared dead at a nearby hospital.

A medical examiner will determine the cause of death.

David and Jackie Siegel were featured in Lauren Greenfield’s 2012 documentary Queen of Versailles, which followed them as they built a second, 90,000-square-foot mansion during the height of the recession. David Siegel later sued Lauren Greenfield for “false and defamatory statements,” but lost the lawsuit in March 2014.

David Siegel is the founder of Orlando-based time-share company Westgate Resorts.

Jackie Siegel is a former Mrs. Florida America.
