An autopsy found that financier Jeffrey Epstein sustained multiple breaks in his neck bones, according to two people familiar with the findings, deepening the mystery about the circumstances around his death.

Among the bones broken in Epstein’s neck was the hyoid bone, which in men is near the Adam’s apple. Such breaks can occur in those who hang themselves, particularly if they are older, according to forensics experts and studies on the subject. But they are more common in victims of homicide by strangulation, the experts said…

People familiar with the autopsy, who spoke on the condition of anonymity due to the sensitive stage of the investigation, said Sampson’s office is seeking additional information on Epstein’s condition in the hours before his death. That could include video evidence of the jail hallways, which may establish whether anyone entered Epstein’s cell during the night he died; results of a toxicology screening to determine if there was any unusual substance in his body; and interviews with guards and inmates who were near his cell.
