An autopsy found that Jeffrey Epstein sustained multiple breaks in his neck bones, deepening the mystery surrounding his death last week, the Washington Post reported, citing people familiar with the findings.

Among the bones broken in the late financier’s neck was the hyoid bone, located near the Adam’s apple for men, the newspaper said. While such fractures can occur in those who hang themselves, especially if they are older, they are more common in victims of homicide by strangulation, the Post reported, citing forensic experts and studies on the subject.
