The US financier was found dead in prison where he faced trial over a fresh raft of sex trafficking charges.
Epstein, 66, admitted prostituting minors in 2008 and spent 18 months in prison before being arrested again on July 6, this year.
Charges of sex trafficking and conspiracy were made against him and he was due to stand trial next year
A Daily Mail source now claims that Epstein told prison staff and other inmates that someone had tried to kill him weeks before he died.
“From what I saw he was finally starting to adjust to prison. I think he was comforted by the rigidity of his new life”
The person had seen him several times at the Metropolitan Correctional Center and claimed he appeared upbeat.
He reportedly said: “There was no indication that he might try to take his own life.
“From what I saw he was finally starting to adjust to prison. I think he was comforted by the rigidity of his new life.”
Epstein’s suicide comes just two weeks after he was hospitalised, Daily Mail reports.
On July 24, Epstein was rushed to hospital under police guard after he was discovered semi-conscious on the floor of his prison cell in the fetal position.
It is not clear whether he was attacked or had attempted to take his own life.
After being found at 7am on Saturday, Epstein was rushed to New York Presbyterian-Lower Manhattan hospital were he was pronounced dead.
The Metropolitan Correctional Center are reportedly launching an investigation into Epstein’s death.
Epstein had an array of high-profile friends including Prince Andrew and Donald Trump although the US president has said he has not had contact with him for over a decade.
He was arrested in July after being acused of arranging sex with underage girls at his New York and Florida homes between 2002 and 2005.
He is also said to have paid some girls to recruit others in a vast paedophile network.
He had pleaded not guilty to the charges.
His death comes two weeks after he was discovered semi-conscious in his prison cell in what appeared to be an initial attempt to take his own life.
The billionaire had been taken off suicide watch before being found dead on Saturday morning which has angered Attorney General William Barr who has vowed to look into the details behind Epstein’s death.
He said in a statement: “Epstein’s death raises serious questions that must be answered.
“In addition to the FBI’s investigation, I have consulted with the Inspector General who is opening an investigation into the circumstances of the death.”
Other Washington figures also want more information.
Congresswoman Alexandria Ocasio-Cortez tweeted: “We need answers. Lots of them.”
Attorney Lisa Bloom, who represents three of the alleged sex trafficking victims, shared a statement from one of her anonymous accusers.
It said: “I will never have a sense of closure now. I am angry as hell that the prison could have allowed this to happen and that I and other victims will never see him face the consequences for his horrendous actions.
“I hope that whoever allowed this to happen also faces some type of consequence. You stole from us, the huge piece of healing that we needed to move on with our lives.”
