Mark Epstein is once again rejecting the official ruling that his brother, disgraced financier Jeffrey Epstein, died by suicide—this time claiming new forensic evidence will soon surface proving he was murdered.
Jeffrey Epstein, a convicted sex trafficker awaiting trial on federal charges, was found dead in his cell at the Metropolitan Correctional Center in New York on August 10, 2019. Authorities ultimately ruled his death a suicide by hanging, a conclusion that immediately sparked public outrage, conspiracy theories, and years of scrutiny.
Mark Epstein, Jeffrey’s younger brother, identified the body and has never accepted the official explanation. In the aftermath of his brother’s death, Mark hired former New York City chief medical examiner Dr. Michael Baden, who publicly stated that the evidence pointed more toward homicide than suicide.
Despite multiple investigations, the Department of Justice and the Federal Bureau of Investigation concluded in a June 2023 report that there was no credible evidence of foul play. Officials acknowledged serious failures at the jail but reaffirmed their position that Epstein took his own life.
Mark Epstein remains unconvinced.
In a July 2025 interview with NBC News, he flatly stated, “More and more, I believe he was murdered,” adding that anyone who examines the available facts reaches the same conclusion.
That claim escalated further during a January 9 appearance on NewsNation, where Mark alleged that new autopsy-related information would be released in February that he says will definitively prove homicide.
He also claimed that when he viewed his brother’s body, the injuries did not match a death by hanging.
“There are only three ways to die in prison,” Mark said. “Suicide, natural causes, or murder. And Jeff was murdered. I want to know who killed him and on whose behalf.”
Mark went on to accuse authorities of orchestrating a cover-up, questioning why officials would continue to defend the suicide ruling.
“Why the charade?” he asked. “Who are they trying to protect?”
He also dismissed recent remarks from Ghislaine Maxwell, who said in August 2025 that she didn’t see how Epstein could have been murdered—though she acknowledged it was technically possible. Maxwell suggested that if it were murder, it may have been an internal prison issue.
Mark rejected her comments outright, saying he wouldn’t trust anything Maxwell says and noting that she never saw Epstein’s body or spoke to him before his death.
In past interviews, Mark has also hinted at political interference. In a November phone interview with NewsNation, he claimed an unnamed source told him that names of conservative politicians were being removed from Epstein-related files. Days later, he went even further on CNN, accusing President Donald Trump of delaying the release of records tied to Epstein.
“He definitely had dirt on Trump,” Mark claimed, suggesting the information could have altered the outcome of an election.
More than five years after Jeffrey Epstein’s death, the case continues to ignite controversy, suspicion, and unanswered questions. If Mark Epstein’s promised evidence does emerge, it could reopen one of the most explosive and debated deaths in modern American history.
