An autopsy has been completed on Jeffrey Epstein under the observation of a federal prosecutor, but further investigation is needed to determine the final cause of his death, New York’s chief medical examiner Barbara Sampson said.

In a statement on Sunday, Aug. 11, Dr. Sampson said a medical examiner performed the autopsy of Epstein on the day, but “the ME’s determination is pending further information at this time.”

She added the performance was made “at the request of those representing the decedent, and with the awareness of the federal prosecutor (Dr. Michael Baden) to observe the autopsy examination. This is routine practice,” The Wrap reported.

According to The Associated Press, Baden is a private pathologist. He was New York’s chief medical examiner in the late 1970s and has been called as an expert witness in high-profile cases.

The death of Epstein in federal custody “raises serious questions that must be answered” as said by Attorney General William Barr, who called for an investigation by the FBI and the Justice Department’s inspector general’s office.

Epstein was reported dead by hanging in his cell at the Metropolitan Correctional Center on Saturday. The billionaire financier, arrested on July 6, awaited trial on sex-trafficking charges by federal prosecutors.

There are some reports that the prison guards, due to staffing shortages and having to work “extreme overnight shifts,” did not follow protocols leading up to Epstein’s suicide.

However, a former prisoner, who spent several months at the correctional facility, claimed there is ‘no way’ Epstein could have killed himself.

Speaking to the New York Post on Aug. 11, the prisoner, who was not named, described that the special cells for inmates like Epstein are 8 or 9 feet high, the sheets provided to them are like paper and not strong enough to make a makeshift noose (Epstein weighed around 180 pounds), while prison officials do not give inmates something that they could kill themselves.

Such claims continue to support a conspiracy theory that some powerful forces could have sought to silence Epstein to avoid being involved in his felony charges.
