Ivana Trump was found at the bottom of the stairs in her apartment in what the New York City Office of Chief Medical Examiner is calling an accidental death. She had reportedly fallen and suffered blunt impact injuries to the torso.

Law enforcement was alerted after someone at her residence asked for a wellness check because they had not seen her in a while. Officers spotted her near the bottom of her stairs when they arrived.
