The FBI is investigating the death of pedophile Jeffrey Epstein, which occurred in jail while he was awaiting trial, and the possible ‘criminal enterprise’ involved, according to the director of the U.S. Federal Bureau of Prisons.

Kathleen Hawk Sawyer revealed the procedure followed by the investigative agency before the Senate Judiciary Committee when questioned by Republican Sen. Lindsey Graham on Nov. 19, according to Fox News.

The death of such a high profile prisoner became the “black eye on the entire Bureau of Prisons.”

“With a case this high profile, there has got to be either a major malfunction of the system or criminal enterprise at foot to allow this to happen. So are you looking at both? Is the FBI looking at both?” the South Carolina senator asked, according to Fox News.

Sawyer replied, “The FBI is involved and they are looking at criminal enterprise, yes.”

Sawyer then explained the procedure followed in the correctional facility when a prisoner at risk of committing suicide is detected, as was said to be the case with Epstein, at which the senator noted that the system had failed in this instance.

“Well, clearly it didn’t work here so we await the report because all the victims of Mr. Epstein have to have their heart ripped out as they will never see justice,” argued Sen. Graham, according to Fox News.

On the other hand, the two guards of the federal prison where Jeffrey Epstein died were arrested and face charges related to the irregular monitoring of the cell where the magnate allegedly committed suicide.

Epstein, arrested in July for child trafficking, was awaiting trial at the Metropolitan Correctional Center. He was found lifeless after an apparent suicide in his Manhattan cell on Aug. 10. He took many dark secrets to his grave since he had deep connections with politicians, royalty, scientists and many others.
