New York, NY. -- Jailed multimillionaire financier and accused sex trafficker Jeffrey Epstein has died by suicide, two law enforcement sources said Saturday, a day after a court unsealed new details of the claims against him.
The Federal Bureau of Prisons confirmed Epstein's death, saying he was found unresponsive in his cell at New York's Metropolitan Correctional Center around 6:30 a.m. ET.
Staff started life-saving measures, and Epstein was taken to a hospital, where he was pronounced dead, the bureau said in a news release.
No foul play is suspected in his death, a federal official told CNN. The bureau's release called it "an apparent suicide," and said the FBI is investigating. Authorities believe Epstein hanged himself, one of the law enforcement sources said.
The New York City medical examiner's office hasn't determined his manner of death.
Epstein had been jailed since early July, when he pleaded not guilty to charges by New York federal prosecutors after an indictment accused him of sex trafficking dozens of underage girls, some as young as 14 years old.
News of Epstein's death comes a day after hundreds of pages of court documents were unsealed in New York federal court, alleging new details of sexual abuse claims against Epstein and several associates.
US Attorney General William Barr said Saturday that he was "appalled" to learn Epstein died of an apparent suicide in federal custody. The Justice Department's inspector general will investigate the circumstances of his death, Barr said.
"Mr. Epstein's death raises serious questions that must be answered," Barr said in a news release. Separately, a source familiar with the situation said Barr was livid at the events surrounding Epstein's apparent suicide and is determined to get to the bottom of what happened.
A spokeswoman for the US Attorney's office in Manhattan, which was prosecuting Epstein, declined to comment on Saturday.
An attorney for Epstein, Reid Weingarten, didn't immediately respond to a request for comment.
