Epstein had been placed on suicide watch after he was found a little over two weeks ago with bruising on his neck, according to a person familiar with the matter who wasn't authorized to discuss it publicly.
According to the New York Times, Chief Medical Examiner Barbara Sampson is "confident the cause of death is suicide by hanging", but she has not yet released an official ruling on the manner or cause of Epstein's death.
A person familiar with the jail's operations told The Associated Press that a guard in Epstein's unit was working a fifth straight day of overtime and another guard was working mandatory overtime the day he was found.
"I was appalled - and indeed the whole department was - and frankly angry to learn of the MCC's failure to adequately secure this prisoner", Mr Barr said.
The Department of Justice and the FBI have both launched investigations into Epstein's death amid questions surrounding the circumstances.
The warden who was supervising the center has been reassigned to the Bureau of Prisons' Northeast Regional Office, according to the Justice Department.
The Justice Department says the warden of another facility in upstate NY has been named the acting warden at MCC. The Department says it will take additional personnel action as warranted.
One of Epstein's guards the night he took his life was not a regular correctional officer, one of those familiar with the case said. Epstein was being held at the Metropolitan Correctional Center awaiting trial for federal charges that he operated a sex trafficking ring with underage girls in the early 2000s.
Federal prosecutors in NY are pursuing a parallel investigation into whether any if his associates will face charges for assisting him in what authorities say was his rampant sexual abuse of girls as young as 14.
Police reports say Epstein's assistants worked like an advance team to facilitate his twice-daily massages, often from high school girls who were paid hundreds of dollars per "appointment".
Federal prosecutors in NY reopened the probe after investigative reporting by The Miami Herald stirred outrage over that plea bargain.
For more than a decade, the union that represents federal correctional officers has been warning of what it describes as "unsound" and "dangerous" staffing levels at prisons around the country.
An inmate in the same unit where Jeffrey Epstein hanged himself heard nothing the morning of his death - but "knows a heck of a lot about what went on", his lawyer said in a new report. "The victims deserve justice, and we will ensure they get it".

Guiffer, who said she was used as a "sex slave" for Epstein from 1999 to 2002, alleged that Maxwell was a "primary co-conspirator" in the scheme.
What happened here, Sasse said, was that wealth and connections "bought injustice".
