There was reportedly shouting and shrieking coming from billionaire sex offender Jeffrey Epstein’s prison cell the morning that he was found dead of an apparent suicide.

CBS News reported Tuesday that the noises were heard from the cell located in Manhattan’s Metropolitan Correctional Center, a variable-security lockup dubbed the “Guantanamo of New York.” It is unclear who was making the noises or when they were heard.

The 66-year-old Epstein was found unresponsive Saturday around 6:30 a.m. He had reportedly used a bedsheet to fashion a noose and hang himself from the top of a bunk bed. When guards found the financier, they attempted to resuscitate him, while saying “breathe, Epstein, breathe.”

Epstein was awaiting trial on sex trafficking charges at the time of his death. He was in the special housing unit of the prison after being moved from suicide watch just days before. He had been placed on the watch after he was found in July nearly unconscious on his cell floor with marks on his neck.

Attorney General William Barr announced Saturday that the Justice Department would be further investigating the circumstances of Epstein’s death.
