NEW YORK (AP) — Ivana Trump, the first wife of former President Donald Trump and mother to his eldest children, died accidentally from blunt impact injuries to her torso, the New York City medical examiner’s office has said.

Police had been looking into whether she fell down the stairs, two people familiar with the matter told The Associated Press on Thursday. They spoke on condition of anonymity because they could not discuss the matter publicly.

The medical examiner’s brief report did not specify when the accident took place. Donald Trump announced Thursday that Ivana died at her home near Central Park on Manhattan’s Upper East Side. She was 73.

Her son Eric Trump said it was “a very sad day, a very sad day,” as he left the home Thursday.

A Czech-born ski racer and businesswoman, Ivana Trump was born Ivana Zelnickova in 1949.

She was married to the former president from 1977 to 1992, and they had three children together: Donald Jr., Ivanka and Eric.

Her death came during a fraught time for the Trump family. Two of her children, Donald Jr. and Ivanka, as well as the former president were due to appear in the coming days for questioning in the New York attorney general’s civil investigation into the family’s business practices. But the attorney general’s office agreed to postpone the depositions — a term for out-of-court questioning under oath — because of Ivana Trump’s death.
