Ivana Trump, Donald Trump's first wife and mother of his three eldest children, passed away

from blunt force trauma to her chest as a result of an unintentional fall,

according to the chief medical examiner of New York City on Friday.

Ivana Trump passed away at the age of 73 a day earlier at her residence in Manhattan,

but the former president made no mention of the reason or manner of her passing. 

Ivana Trump was discovered at the foot of her home's steps on Friday, according to a

representative for the chief medical examiner's office in New York City.
