Officials are reportedly investigating Ivana Trump’s cause of death.

The Daily Wire reports:

The Associated Press reported that law enforcement officials are looking into whether Ivana Trump fell down the stairs because she was found unconscious near the bottom of the staircase in her home. Officials believe that her death was an accident.

Local news stations reported that she was dead by the time paramedics had arrived on scene after they received a call about someone in cardiac arrest. City officials will still investigate and release a report on the official cause of death.

“It is with deep sadness that we announce the passing of our beloved mother, Ivana Trump,” Trump’s children said in a statement. “Our mother was an incredible woman — a force in business, a world-class athlete, a radiant beauty, and a caring mother and friend. Ivana Trump was a survivor. She fled from communism and embraced this country. She taught her children grit and toughness, compassion, and determination. She will be dearly missed by her mother, her three children and ten grandchildren.”

Donald Trump announced his ex-wife’s death on Thursday afternoon in a post on social media, writing: “I am very saddened to inform all of those that loved her, of which there are many, that Ivana Trump has passed away at her home in New York City.”
