Jeffrey Epstein died of suicide by hanging, a medical examiner in New York has confirmed.
The disgraced financier, 66, was found dead in his prison cell on 10 August.
His death sparked outrage as he was facing a 45-year sentence if convicted of multiple counts of sexually abusing underage girls.
Epstein had been on suicide watch at the prison, having been found with marks around his neck on 23 July.
He was reportedly taken off suicide watch after a week and put back into the high-security housing unit where he was less closely monitored.
Attorney General William Barr, who ordered an investigation after the death, said officials had uncovered "serious irregularities" at the prison.
The FBI and the justice department are investigating.

Prison officials told The New York Times that Epstein had not been checked on for three hours before he was found.
One of two guards was no longer a correctional officer, having being moved to a non-guarding role in the prison, and had agreed to take on work as a guard as overtime, according to the newspaper.
Earlier this week the Washington Post reported that a post-mortem had revealed Epstein had broken several bones in his neck.
The Post said sources revealed he had broken the hyoid bone close to the Adam's apple, which is not commonly broken in death by hanging. However it is more commonly broken in older men.
US district judge Richard Berman, who is in charge of the criminal case against Epstein, wrote to the jail's warden on Monday seeking answers about the earlier episode saying it has "never been definitively explained".
The warden said the internal investigation into the first incident had been completed, but details could not be revealed because they would be incorporated into a new report.
Friday's ruling from the medical examiner came a day after two more women sued Epstein's estate, saying he sexually abused them in 2004.
The women, one who was 18 and one who was 20, were working as hostesses in a Manhattan restaurant when they were recruited to give him massages, they claim.
Epstein was already a registered sex offender after pleading guilty in 2008 to Florida state changes of unlawfully paying a teenage girl for sex.
However that conviction was also shrouded in controversy, as he pleaded guilty in exchange for the justice department's agreement not to prosecute him on similar charges.
He served 13 months in jail and agreed to register as a sex offender under the 2008 plea deal, which is now widely seen as too lenient. Federal prosecutors in New York had reopeRead More – Source
