Epstein, who was in jail awaiting trial on sex-trafficking charges, had been found dead in his cell Saturday morning in what authorities had called an "apparent suicide."
The medical examiner announced Sunday evening that she had completed Epstein's autopsy but was seeking more information before making the results public.
The Washington Post reported Thursday, citing two people familiar with the situation, that an autopsy of Epstein revealed broken bones in his neck.
Forensic experts told the Post that one of the broken bones, the hyoid bone, can occur from hanging but is more frequently associated with homicide victims who died from strangulation.
Epstein's death sparked a slew of conspiracy theories over the weekend, with many questioning the circumstances surrounding the sudden death of the disgraced financier. Questions have been raised as to why Epstein, who had been placed on suicide watch in late July after reportedly being found with marks on his neck, was not more closely observed.

Epstein had been accused of sex trafficking activities involving underage girls between 2002 and 2005. He was convicted in 2008 on separate sexual misconduct charges and forced to join the sex offender registry. His 2008 plea agreement became the subject of much scrutiny following a Miami Herald report last year.
