A source told the Mirror that Jeffrey Epstein kept a detailed, secret diary for 'insurance' purposes, detailing his relationships with rich and famous people

Jeffrey Epstein allegedly had a secret diary that contained information about his friendships with powerful people which he kept as an 'insurance policy.'

Pedophile Epstein - who palled around with notables including Prince Andrew, Bill Clinton and Donald Trump - was said to have kept a 'meticulously detailed' diary of his many friendships with the rich and famous, according to the Mirror.

Sources told the newspaper that Epstein, a convicted sex offender who faced federal charges for the sex trafficking of minors in Florida and New York, kept the diary as a form of insurance.

It's existence supposedly became known when Epstein's alleged victims' lawyers obtained a statement from Prince Andrew as part of US authorities' investigations.

The former financier, 66, was found hanging in his prison cell shortly before 7am and was rushed to nearby New York Presbyterian-Lower Manhattan hospital where he was pronounced dead.

His death came just hours after a US court unsealed a bombshell cache of documents pertaining to a 2015 lawsuit filed against Epstein's longtime girlfriend, Ghislaine Maxwell, were unsealed, revealing damning new details about Epstein's alleged crimes.

NYC's Chief Medical Examiner has completed Jeffrey Epstein's autopsy but said Sunday more information is needed before a cause of death can be determined.

But, now that he's dead, there's speculation that Epstein's secret diary surfacing could lead his powerful friends to panic about what he'd written.

'All Jeff ever had he bought, including his friends,' a source told the Mirror. 'He used his wealth to buy buddies and then bestow his money on those he courted.'

The sourced added that Epstein 'knew' that being friends with rich and famous people 'brought him protection' and that was why he kept the detailed diary - 'in case he ever needed it.'

Word of Epstein's secret diary broke as the alleged victims of his sex trafficking and federal authorities said they intend to keep pursuing their cases against him, despite his death.

Lawyer Jack Scarola, who represents many of Epstein's alleged victims, told the Mirror that his clients are 'hopeful that other victims may be relieved of some of the fear that has prevented them from coming forward while Epstein was still alive.'

Epstein's victims' lawyers and federal authorities said that they would continue to investigate the victims' claims and indicated that they would go after Epstein's (left) accomplices, including girlfriend Maxwell (pictured with Epstein at right in 2005)

In addition, Scarola noted, 'There is little doubt victims who have not yet come forward have information that will help bring Epstein’s co-conspirators, enablers, recruiters, and fellow traffickers to justice.'

He also said that his clients wouldn't 'rest easy until all of those who participated in Epstein’s crimes are brought to justice – no matter their past or current station in life.'

US Attorney Geoffrey Berman said in a statement Saturday: 'To those brave young women who have already come forward and to the many others who have yet to do so, let me reiterate that we remain committed to standing for you.

'And our investigation of the conduct charged in the Indictment — which included a conspiracy count — remains ongoing.'

Berman's reference to the conspiracy count suggests that accomplices to Epstein's crimes could soon face charges.

Among the alleged accomplices named in civil suits are Epstein's longtime girlfriend, Maxwell, and former employee Nadia Marcinkova.

Following Epstein's death, many of his alleged victims spoke out.

Jennifer Araoz, who accused Epstein of raping her in his Manhattan mansion when she was 15 years old, said: 'We have to live with the scars of his actions for the rest of our lives, while he will never face the consequences of the crimes he committed the pain and trauma he caused so many people.'

'Epstein is gone, but justice must still be served. I hope the authorities will pursue and prosecute his accomplices and enablers, and ensure redress for his victims.'

Araoz's attorney, Kimberly Lerner, said: 'There's a whole network that enabled him and allowed this to happen. It's time that everyone who was a part of this be held accountable.'

Virginia Roberts Giuffre alleged in a 2016 deposition that she was a teenager when she was forced to have sex with George Mitchell, a former Senate Majority leader who represented Maine from 1980-95, former New Mexico Governor Bill Richardson and Prince Andrew, Duke of York.

Prince Andrew has strenuously denied all allegations against him.

Giuffre's attorney, Sigrid McCawley, said in a statement that 'the reckoning of accountability begun by the voices of brave and truthful victims should not end' with Epstein's death.

Jena-Lisa Jones claims she was 14 when she became a victim of Epstein in Florida. The now-30-year-old said in a statement: 'God will have his judgement now.'
