As many as 20 correctional officers who work at the federal detention center where Jeffrey Epstein died by suicide received grand jury subpoenas last week relating to an investigation into his death, according to a source with knowledge of the situation.
More subpoenas could be in the works as the investigation widens, CNN's source added.
A spokeswoman for the Justice Department declined to comment Thursday.
Both the FBI and the Justice Department's Inspector General are investigating the circumstances around Epstein's death.
It's possible that the criminal investigation was simply prompted by Epstein's death, but CNN's exact words are "an investigation into his death." I assume that DAG Rosen (who supervises the FBI) and Barr are being continually updated, but that the local DoJ (FBI and USA) are handling the investigation.
