Accused pedophile and wealthy Manhattan financier Jeffrey Epstein was found injured and in a fetal position inside his cell at a New York City jail, according to sources close to the investigation.

Epstein, who is being held in Metropolitan Correctional Center during his trial for conspiracy and sex trafficking, was found semi-conscious with marks on his neck, two sources told News 4. Investigators are trying to piece together exactly what happened, saying details remain murky.

Two sources tell News 4 that Epstein may have tried to hang himself, while a third source cautioned that the injuries were not serious and questioned if Epstein might be using it as a way to get a transfer.

A fourth source said an assault has not been ruled out, and that another inmate was questioned. The inmate who investigators have talked to in Lower Manhattan facility has been identified as Nicholas Tartaglione, according to two sources. Tartaglione is a former police officer in Westchester County who was arrested in December 2016 and accused of killing four men in an alleged cocaine distribution conspiracy, then burying their bodies in his yard in Otisville in Orange County, according to court records.
