CBS News: "Shrieking" heard from Jeffrey Epstein's cell the morning he died

From an unbylined, slapdash item at CBS News:

CBS News has learned that the morning of Jeffrey Epstein's death there was shouting and shrieking from his jail cell. Guards attempted to revive him while saying "breathe, Epstein, breathe."

The rest of the story is all recap, offering no clarification at all about who was shrieking or even to make clear that it was after Epstein died. The only other new detail in it is that his brother was summoned to identify his body.

This is obviously going to be everywhere today. Is the suggestion that it was a guard or other jail staffer upon discovering his body? That CBS News chose such an ambiguous headline, allowing that it might have been Epstein shrieking, is the stuff institutional regrets are made of.
